Today’s Wonder of the Day was inspired by Ryan. Ryan Wonders, “how long would it take to reach the oort cloud, the barrier of our galaxy” Thanks for WONDERing with us, Ryan!
Have you ever gotten the chance to peek through a telescope pointed at the night sky? If so, you may have had the chance to see a curious object that looked a bit like a star with a long tail. What could it be? It's probably a comet!
Comets are huge chunks of rock and ice that come from the farthest reaches of our solar system and even interstellar space. In fact, some scientists believe they're leftovers from the birth of the solar system.
As a comet gets closer to the Sun, heat causes it to leave a debris trail of dust and gas. This is the signature tail we see through a telescope. Observations of comets long ago led scientists to theorize the existence of a spherical cloud of rocky, icy objects that form a shell around the Sun and our solar system.
This theoretical cloud is known as the Oort Cloud, named after Dutch astronomer Jan Oort who theorized its existence. An Estonian astronomer named Ernst Öpik also developed similar theories, so sometimes the cloud is called the Öpik-Oort Cloud.
So exactly where is the Oort Cloud? To reach it, you would have to travel to the outer edges of our solar system, way past Neptune and Pluto. Astronomers believe it begins somewhere between 2,000-5,000 Astronomical Units (AU) from the Sun. An AU is defined as the average distance between Earth and the Sun, or about 93 million miles.
The size of the Oort Cloud is hard for the human mind to imagine, because astronomers believe it could stretch out as far as 50,000 AU from the Sun. Some astronomers theorize it could extend as far as 100,000 AU or even 200,000 AU from the Sun. That puts its outer boundary at anywhere from 4 trillion miles away to over 17 trillion miles away!
How many icy objects could fit into that enormous space? Some scientists estimate there could be two trillion or more such objects in the Oort Cloud. Most of these objects are believed to be made up of ammonia, methane, and water (ice).
Since the Oort Cloud is so far away from the Sun, the objects within it are susceptible to the gravitational pulls from other stars and the Milky Way galaxy itself. Occasionally, objects will be knocked out of their orbits by these gravitational effects, sending them either out into deep space or into the solar system toward the Sun.
Objects that are knocked toward the Sun often become long-period comets (comets with orbits longer than 200 years). The observation of comets is what led Oort and Öpik long ago to theorize the existence of the Oort Cloud to explain their origin.
For example, Voyager 1, the fastest and farthest space probe that's currently exiting the solar system would still need about 300 years to reach the Oort Cloud. Unfortunately, the generators that power its scientific instruments will have run out of fuel hundreds of years before it would reach the Oort Cloud. | <urn:uuid:74412888-053f-483f-863d-e85ff1a3be9a> | CC-MAIN-2018-05 | https://wonderopolis.org/wonder/where-is-the-oort-cloud | s3://commoncrawl/crawl-data/CC-MAIN-2018-05/segments/1516084890582.77/warc/CC-MAIN-20180121120038-20180121140038-00533.warc.gz | en | 0.946156 | 660 | 4.5 | 4 |
Generation is one of those words that have a lot of different meanings. The two most common involve groups of people and some things they have in common.
One type of generation involves members of your own family. You and any of your brothers and sisters, your first cousins (your aunts’ and uncles’ children,) second cousins your great-aunts’ and great-uncles’ grandchildren,) and anyone else on your level of the family tree is part of the same generation. Your parents and their first, second, and third (and so on) cousins are part of a generation too. If someday you have your own children, your children and your cousins’ children will be part of the same generation. Generations might be able to be traced back hundreds of years, depending on if good records were kept of family histories.
Another type of generation goes beyond your family. It involves anyone who is about your same age. This type of generation does not have defined rules, but it involves people who are alive at the same time and who experience the same events. People who were kids when the Harry Potter movies first came out are part of the same generation. People who were old enough to join the army during the Iraq war are part of the same generation. The shared experiences can be anything. Every one who is a kid right now is part of your generation. Think about the experiences you share that today’s grown-ups did not experience when they were kids. | <urn:uuid:dadbfbed-ef83-4c0f-baf4-97ab0632f4ed> | CC-MAIN-2015-48 | http://whyzz.com/what-is-a-generation | s3://commoncrawl/crawl-data/CC-MAIN-2015-48/segments/1448398466178.24/warc/CC-MAIN-20151124205426-00127-ip-10-71-132-137.ec2.internal.warc.gz | en | 0.976943 | 302 | 3.328125 | 3 |

ATLANTA – The U.S. needs a more holistic approach to control the spread of sexually transmitted infections, a leading expert in the field says.
Health officials should search social networking websites and use more-comprehensive screening tests to trace the spread and treat of such infections, Dr. Peter Leone, professor of medicine and epidemiology at University of North Carolina, said.
"We really need to prioritize. Given the at-risk population, we really need to ask what the primary drivers are" for STIs, Leone said in a conference presentation here. "Otherwise, we're continuing to treat the pathogen when the problem is not the pathogen, it’s the environment" where the pathogen spreads.
Leone, who is also medical director of the North Carolina HIV/STD Prevention and Control Branch, addressed other experts March 14, the last day of the four-day International Conference on Emerging Infectious Diseases here.
Social networks and STIs
Leone emphasized the use of social networks when an infection is found. By working with a patient to identify the people he or she had sexual contact with, efforts can be focused on higher-risk individuals, he said.
Currently doctors inform patients about laws requiring patients to notify their past partners, but it would be more effective if health care workers reached out through social networks to people who know someone who is infected. This could lead to the screening of people who, based on their behavior, are at high risk, instead of just the people along a single path of infection.
This is important, Leone said, because STIs are often asymptomatic and can spread without the person's knowledge. Furthermore, many men are not accessing the health care system regularly for physicals and therefore may have infections that are being missed.
Leone noted that some public health officials have expanded their screening efforts by creating a system for people to mail in samples for testing.
A broader view
Another needed step, Leone said, is to begin considering how to best curb the spread of all STIs together, rather than as individual diseases.
The narrower focus has created some problems in the past, he said. As an example, Leone cited public health messages that informed people that the risk of contracting HIV is lower for oral sex than for vaginal intercourse. When those efforts were put in place, he said, health care providers should have been made aware that they needed to be more vigilant in oral screening tests for other STIs.
As it is, screening tests are often conducted only on the genitals. That approach "misses the overwhelming majority of STIs that are out there," Leone said.
One 2005 study of nearly 600 HIV patients in San Francisco, for example, found that nearly all chlamydia and gonorrhea infections were in body parts other than the genitals. Over 10 percent of patients had an infection, but researchers concluded that without throat and rectal testing, they would have missed 79 percent of chlamydia infections and 100 percent of gonorrhea infections.
Leone added that the inflammation caused by one STD can make a person more susceptible to another, even when the symptoms aren’t enough to send the person in for testing.
The conference was sponsored by the Centers for Disease Control and Prevention and managed by the American Society for Microbiology.
Pass it on: A different approach to screening is needed to better control sexually transmitted infections, an expert says. | <urn:uuid:4403f359-2e71-4bed-83d8-132ebc24d0a6> | CC-MAIN-2015-40 | http://www.livescience.com/19111-sexually-transmitted-infections-social-networks.html | s3://commoncrawl/crawl-data/CC-MAIN-2015-40/segments/1443736682773.27/warc/CC-MAIN-20151001215802-00057-ip-10-137-6-227.ec2.internal.warc.gz | en | 0.965223 | 708 | 2.6875 | 3 |
How much of your DNA comes from ancient humans? Where do you think humans originated and how did we spread across the globe? The Department of Biochemistry at the University of Wisconsin–Madison invites you to a campus-only talk on Thursday, Dec. 8 and a public talk Friday, Dec. 9 by esteemed researcher Svante Pääbo to explore his answers to these questions.
Pääbo, of the Max Planck Institute for Evolutionary Anthropology in Germany, is known as one of the founders of paleogenetics, which is the study of ancient DNA and genetics to understand the past. He specializes in retrieving genetic material from ancient humans, like Neanderthals, who became extinct about 40,000 years ago.
The Thursday, Dec. 8 campus-only talk titled “An Ancient DNA View of Human Origins” will be from 3:30-4:30 p.m. in Room 1125 of the Hector F. DeLuca Biochemistry Building at 420 Henry Mall. The public talk on Friday, Dec. 9 will be from 4-5 p.m. in the Headquarters Auditorium at the Wisconsin Historical Society. That talk is titled “Of Neandertals, Denisovans, and Modern Humans.” Both talks are free but require an easy RSVP. To RSVP for the campus-only talk click here, and to register for the public talk click here. Each talk will be followed by a short reception with hors d’oeuvres. Live audio streaming of the public talk is available here for those unable to attend. Please note that the link supports a maximum of 100 listeners.
“We are very excited to have this world-renowned scientist coming to UW–Madison to share his research with us,” says Aseem Ansari, a professor in the Department of Biochemistry who invited Pääbo to speak. “His work recovering ancient DNA and analyzing it in the lab to illuminate our past is so fascinating to me, my fellow scientists, and the public. I can’t wait for him to share it with everyone.”
Through his work, Pääbo has drafted the genome sequence of Neanderthals and discovered a new group of ancient humans by analyzing DNA found in the Altai Mountains in Asia. By examining these two genomes and the genomes of today’s humans, he discovered people living outside of Africa today share 2% of their genomes with Neanderthals.
He has also developed a theory for how modern humans emerged from Africa less than 100,000 years ago and genetically mixed with Neanderthals and other archaic human populations. His findings also tell the tale of how some genes that humans have obtained from Neanderthals are advantageous, while others influence susceptibility to diseases still today.
“Pääbo’s work has so much relevance to us today, using modern technologies to fill in the blanks of our past as humans,” Ansari says. “It is a great example of how laboratory research becomes applicable by helping us understand our past and think about our future. We hope you’ll join us for a talk.”
Pääbo’s talks are part of the Biochemistry Colloquium’s International Steenbock Lectureship, funded by the Harry Steenbock Lectureship in Biochemistry and Life Sciences. Harry Steenbock was a highly regarded biochemistry professor who discovered the irradiation process for producing vitamin D.

Look further into the capitalize meaning… If a company capitalizes its costs, then it means that the charges do not show up on the income statement. However, the expense will show up as a depreciation expense. The total amount can also be seen on the balance sheet accounts. This means that a company has the ability to spread the amount of its expenses over time. This means that the net income for that company will have a smoothing effect over the life of the investment or asset, and in the first year artificially inflates the net income.
For further explanation, look at the following capitalize example.
For example, Beat Box Co. manufactures and assembles stereo systems. Recently, Beat Box has just leased a new piece of equipment for its operations. Instead of the company incurring the cost all at once it has decided to capitalize the cost over time. Thus, if the entire cost of the equipment was $1,000, and it depreciates over ten years then the entire amount of expense incurred each year on the balance sheet would be $100. Note that if the amount of income was $600 for the next ten years then the amount in the first year would be a loss of $400. However, because this amount was capitalized the company will show a profit of $500 each year for the next ten years.

At the very beginning of April, I’d like to share with you a few ideas about a plant which had much more significance for our ancestors than ever it has for us.
Mark you, in this sophisticated age we don’t rate one of our ancestors’ delicacies at all, regarding the plant as a pest rather than as a blessing. For the plant that they so welcomed was the Stinging Nettle, Urtica dioica, formerly called ‘heg-beg’ in some parts of Scotland. Most commonly found growing on waste land, nettles are rich in minerals such as iron, calcium, manganese and potassium and in vitamins A and C. Their leaves are the natural equivalent of the vitamin tablets so commonly taken today; and they served the same purpose as these tablets, replenishing bodies run down by long Winter months of cold, dull weather.
But though most of us wouldn’t dream of including nettles as any part of our diet nowadays, recipes for nettle soup are still frequently found in contemporary Scottish recipe books; and Claire Macdonald, the Scots hotelier and exponent of traditional cookery, has written: “Nettles are traditionally eaten in the Spring as a means of cleansing the body. I don’t think you need an excuse to eat nettles - they are fresh-tasting and make a very good soup and they are delicious if they are picked when they are very tiny - about 5-6 inches, or 10-12 centimetres tall. If you wait until they are quite tall, they have a bitter taste. As with all soups, nettle soup will be as good as the stock used in the making. Wear gloves to pick the nettles.” I particularly like that last point and recall a childhood trick I used to play on my more naïve friends. “Nettles don’t sting this month,” I’d say, tempting them to touch one. And as I ran off, I’d call, “They don’t sting this month but they do sting you!”
But our ancestors did more with nettles than simply turn them into soup. They also brewed nettle ale; ate boiled nettle leaves as a vegetable rather like cabbage; and made nettle tea, which has made something of a comeback in recent years with herbalists. You can actually buy nettle tea-bags from some herbalists’ shops, tea-bags which yield a tea which is thought to relieve asthma, to lower blood pressure and to be a good laxative.
But the nettle, which thrives in poor soil and is native to most parts of Scotland, has fallen from favour with most of us. Because it is a native plant, it springs up readily whenever the opportunity occurs; and we describe it as a weed precisely because it thrives where we don’t want it to grow. So today’s gardening books are more likely to include tips on how to get rid of nettles rather than suggest some of the many uses they have. Maybe the happy medium is to tolerate nettles in some less-easily accessible parts of the garden, perhaps by allowing them to grow among taller plants at the back of borders. The internet will yield many tips on making use of the plants’ leaves and you might just derive some of the benefits our ancestors enjoyed.

This is the story of how the Aztecs began as a small band of wild Chichimec nomads and left their original home under the guidance of Huitzilopochtli, searching for their own promised land. In the epic saga focusing specifically on the rise of the Mexica and Huitzilopochtli, this legend comes after the Battle of Coatepec and before the rebellion of Malinalxochitl.
First Steps From Aztlan
As told by Cehualli
Long ago, after the seven tribes had parted ways at Chicomoztoc, the Place of Seven Caves, the Mexica lived as simple nomads in their homeland of Aztlan. They were a wild and hardy clan, not yet educated in the sophisticated ways of the Toltecs, but brave and adventurous. They lived by hunting the wilderness, always on the move in search of new game. In short, they were Chichimecs, barbarian nomads.
One day, in a year of the Flint Knife, one of the teomama, or priests who carried the sacred bundles, received a vision. It was the priest who carried Huitzilopochtli’s bundle (tlaquimilloli), the Teotl who was the special protector of the tribe. Huitzilopochtli told him that He had big plans for them. “Be bold! You will travel south to the unknown lands of Anahuac, to a place where your people will found a great empire. You will be numerous and powerful, feared in war. You will gather rich tribute, land, slaves, and sacrifices in My name.”
“How can this be?” replied the priest in awe. “We’re just a small clan of simple nomads, nothing like the mighty Toltecs of wondrous Tollan where Quetzalcoatl once ruled.”
Huitzilopochtli scoffed at his fear with all the bravado of a daring young warrior eager to test his skills. “Now you are small and weak, but if you follow Me, I will guard and guide you, destroying those who would harm you and leading you to victory. I promise you a sign when you have reached the right place — you will see an eagle perched on a nopal cactus, eating a heart. When you find this spot, build My temple there. Now, take heart and tell My wishes to the chieftains! I am impatient and long to start the journey!”
As the vision faded and the presence of the god left him, the priest went to tell His charge to the chiefs. They consulted among themselves and decided to trust Huitzilopochtli, the Protector of Men. “He’s never led us wrong before,” they said. “Even though these things seem impossible, we will trust Him and migrate south. Perhaps we will die, perhaps we will be a glorious empire after all. We will see!”
They gathered their poor possessions and set out from Aztlan, the White Place, a land to the northwest of the place they would eventually call home, Tenochtitlan. They were the seventh and youngest tribe to leave, but they would one day become the greatest of all, the Mexica-Tenochca, Aztecs. | <urn:uuid:253b7cbe-19e0-498f-9584-0a0f83d04f2c> | CC-MAIN-2020-05 | https://tlacatecco.com/tag/white-land/ | s3://commoncrawl/crawl-data/CC-MAIN-2020-05/segments/1579251799918.97/warc/CC-MAIN-20200129133601-20200129163601-00022.warc.gz | en | 0.961226 | 705 | 2.578125 | 3 |
“The Workshop on Aging Population and Health: The Longitudinal Study and the Role of Population Collaborators in Community Based Care for Older People” was held by the General Department for Population and Family Planning (GOPFP) under the Ministry
Health in partnership with the United Nations Population Fund (UNFPA), the Economic Research Institute for ASEAN and East Asia (ERIA) of Japan and the Institute of Population, Health and Development (PHAD).
aging is one of the most significant social transformations globally with one in 11 people in the world over age 65 this year, said GOPFP Deputy General Director Nguyen Thi Ngoc Lan in her opening remarks.
Vietnam officially entered an “aging phase” in 2011 with 7 percent of the population above age 65, she said. This year, the figure grew to 8.3 percent, equivalent to over 8 million people.
Such rapid pace of aging has placed great burden on Vietnam’s health care for the elderly but the country has yet to prepare for that, she said.
In 2018, the ERIA teamed up with the PHAD to conduct a longitudinal study on the older people and health of the elderly on about 6,050 older people in 10 cities and provinces in Vietnam from December 1, 2018 to May 31, 2019.
The findings show that over 57 percent of old people asked were women, over 82 percent of them got married, and about 70 percent lived in rural areas. The percentage of the older people who live alone is relatively low, around 11 percent for women and 4 percent for men.
It also reveals the elderly’s health status. Accordingly, more than 62 percent of the respondents said they were suffering from high blood pressure, 86 percent of whom were receiving treatment. About 40 percent did not know they have high blood pressure.
About 56 percent were satisfied with sleep, over 6 percent showed signs of depression and 4.4 percent showed signs of dementia. About 91 percent owned a health insurance card.
Speaking at the event, Dr. Nguyen Ngoc Quynh, a programme official from the UNFPA, said that the population aging in Vietnam is partly due to falling birth rates in all six socio-economic regions and ethnic minority groups.
Vietnam needs to have a health care strategy and ensure good health for the elderly during their life circle, he said, stressing the importance of initial health care, preventive care, medical and non-medical care, health care services at home and in the community. | <urn:uuid:fe5b3512-c82e-4357-9f1b-0b238c03ab6e> | CC-MAIN-2020-40 | https://english.vov.vn/society/vietnam-to-become-superaging-country-by-2050-407507.vov | s3://commoncrawl/crawl-data/CC-MAIN-2020-40/segments/1600400244231.61/warc/CC-MAIN-20200926134026-20200926164026-00649.warc.gz | en | 0.962721 | 512 | 2.546875 | 3 |
Golden Weeping Willow – Salix alba ‘Tristis’
Golden weeping willow is a fast-growing, massive tree reaching up to 80 feet in height. Although main branches grow upward, the secondary ones grow straight down, creating the graceful weeping effect for which it is renowned. The trunk is brown with a distinctly corky bark. The pendant stems are yellow green. The narrow, deciduous leaves are pointed and green to yellow-green above, pale below.
Often found growing wild along streams and watercourses, the golden weeping willow has characteristics that might have one regretting a decision to use them in home landscapes. Although willows in general grow easily in most moist soils, they require watering during periods of drought, lest they lose their leaves in copious quantities. The brittle wood is shed regularly, creating a never-ending litter problem.
The weeping habit creates dense shade and if left untrimmed, the drooping branches will grow to the ground, effectively blocking all sunlight. Only plants that can tolerate deep shade will grow under these trees. Locate weeping willow only where there is adequate space for its large, imposing form. Not for residential lots, it is best located near water where soil will be undisturbed. It is often planted near retention ponds and lakes for a dramatic softening effect.
Care should be taken not to locate weeping willows near underground water or sewer lines or close to septic tank drain fields where the roots could cause significant damage. Roots are aggressive and will spread about three times the distance from the trunk to the edge of the canopy and often grow on the soil surface.
Willow bark was steeped as tea by native Americans, and the young twigs and bark chewed to relieve headaches. It was later found the active ingredient was salicylic acid, the basis of today’s aspirin. “Salicylic” derives from the willow genus Salix, as does the family name Salicaceae.
Weeping Willows should be grown in full sun or very light shade and will tolerate a wide range of soil conditions, including alkaline pH. All willows will need initial pruning and training when young to develop a strong, central trunk with branch crotches as wide as possible. This will increase the longevity of the tree and help overcome the problem with brittle wood, but the trees are usually still short-lived, rarely reaching 60 years old.
Family Salicaceae — Willow, Cottonwood, Aspen
There are only two genera in this family, Salix (willows), with about 300 species, andPopulus (poplars), with barely 40 species. Salicaceae are found throughout the temperate parts of the world, with the majority of species occurring in the north; both willows and poplars have a strong affinity for water. | <urn:uuid:dc861f4b-cade-4200-a276-c4811268dc24> | CC-MAIN-2020-34 | https://www.cirrusimage.com/golden-weeping-willow.htm | s3://commoncrawl/crawl-data/CC-MAIN-2020-34/segments/1596439740423.36/warc/CC-MAIN-20200815005453-20200815035453-00489.warc.gz | en | 0.946546 | 587 | 3.5 | 4 |

Novel Presents a Better Way for Kids to Learn
FITHIAN, Ill. – In the novel “Conspiracy” (published by Trafford Publishing) Dr. Edwin M. Swengel presents Plainston, a Midwestern city that is literally walled off from the outside world—a place where there are no cars, no hunger, no religious strife. Karl Kornhauer, a national political writer, has been asked to investigate the conspiracy talked about both inside and outside the walls. As he explores Plainston, he tries to discover what makes the city and its residents so wonderfully different. The quest finally leads him to the year-round schools which are like no other schools he has ever seen. Kornhauer spends months in the schools, observing what has replaced the traditional system so familiar to most Americans.
Jane Swengel Creason finished the novel after her father’s death. She says, “Our educational system is constantly under attack—and rightfully so. Yet we continue to hold to age-related classrooms, grade-level achievement standards, testing and more testing, teacher-led classrooms, and grades which reward success or identify mediocrity and failure. Characters of all ages make Dad’s unique schools come alive and illustrate his concept of Mutual Instruction, which means simply kids being trained to help each other.” Creason also explains that even though her father’s purpose was to present his ideas for change, “Conspiracy” is an engaging story.

California’s heat waves are going to be getting longer and hotter in the coming decades, according to a new climate modeling study commissioned by the California Air Resources Board (CARB) and the EPA. The authors predict that heat-related deaths among California’s 65-and-over population could spike more than nine-fold by 2090. According to the study, currently more than 500 elderly people die annually from heat-related causes.
Using IPCC climate projections, the study models how climate change will impact California up and down the coast, including coastal cities like San Francisco and inland cities such as Riverside and Fresno.
Lead author Scott Sheridan, a geographer at Kent State University, says that the projected increase in heat-related deaths among those 65 and over are due in part to physiological reasons, but also to growing population size of this age group. By the end of the century, he says, the state’s population of people in this age bracket will increase from 4 million to 15.7 million. Sheridan says California communities that are already used to dealing with hotter temperatures, like the inland city of Fresno, may be better prepared to deal with the heat than relatively cooler coastal cities.

While most of the nation bakes, California keeps its cool–and not just along the coast
Climate scientist Phil Duffy and meteorologist Jan Null joined Michael Krasny on KQED’s Forum to discuss California’s cooler-than-usual summer and what it might reveal about climate change in the region. The upshot? We don’t really know.
“I think we’re seeing plain old climate variability,” said Duffy, who is a visiting scholar at Stanford and the Carnegie Institution for Science and chief scientist for Climate Central, a Climate Watch content partner.
Null agreed with Duffy, saying that in any given year, “stuff happens,” which can’t necessarily be attributed to a larger trend.
“It’s hard to take an individual year and say ‘This is the result of climate change’,” said Null. “It could be just the roll of the dice. If we see a lot of stuff happening over the next decades, then we’re talking about climate change.”
Null said this summer’s cool weather is due to a persistent trough of low pressure along the west coast.
“Anytime you have that for an extended period of time, you get what people call ‘unusual’ or ‘freakish’ weather,” he said. Continue reading
Hotter temps could set the stage for more — but the science is complex
On July 5, a massive dust cloud, or haboob, swept across Phoenix, Arizona, brought by the North American monsoon. (Photo: Greg Gorman/Flickr)
By Alyson Kenward
On Tuesday night, a massive dust storm rolled into Phoenix, Arizona knocking out power in much of the city, reducing visibility to nearly zero, and grounding flights overnight. Photos of the 100-mile wide dust cloud swallowing the city circulated yesterday, and the event looked practically apocalyptic. In fact, if the photos weren’t in color, and there weren’t YouTube videos of the dust storm, I would have thought I was looking at old-timey images from the 1930’s dust bowl. Now, a couple days later, lingering dust in the air has triggered allergy-like symptoms for many people. Continue reading

It’s not so much the planet we need to worry about, it’s each other. And ourselves.
That’s the message of the documentary Climate Refugees, which aims to portray “the human face of climate change.” The film takes viewers to flooded disaster zones in Bangladesh and China, to tiny island nations like Tuvalu under threat from sea level rise, and to the desert wastelands of Sudan, where, according to the UN, the devastating war in Darfur has been driven partly by climate change.
Extreme weather events are expected to become more common as the climate continues to change, raising the odds for disastrous floods like the ones Pakistan last year, which displaced more than 20 million people, and major droughts which will likely increase desertification in vulnerable areas of Africa and Asia, threatening food and water supplies for millions of people.
And all of those people will need someplace to go.
Pacific storm makes for some high tides and scary waves on the Bay
Waves slosh on to San Francisco's Embarcadero during Thursday's "king tide" (Photo: Gretchen Weber)
Take naturally-occurring extremely high tides, and add to them high winds and torrential rain, and you get some pretty big seas.
At least, that’s what I got out on the San Francisco Bay today. How big exactly, is hard to say (our uneducated guessed ran the gamut), but they were big enough to wash over the bow of our 26-foot boat on more than one occasion and to keep most of us aboard holding on for dear life for much of the three-hour voyage. What I can say for sure is that as I type this blog post, four hours later, my body still feels like I’m rolling up and down and back and forth on some stormy seas.
We braved the weather today to check out the latest round of “king tides” and see how they affect low-lying shorelines in places like Crissy Field, Treasure Island, and SFO. The seas were so rough that we didn’t make it all the way to the airport, but we did see waves crashing over the sea wall along the Embarcadero just south of the Ferry Building (see video below). At Crissy Field, the beach was nearly submerged and a small footbridge near the mouth of the estuary was almost awash. Continue reading
High tide at Pier 14 in San Francisco on January 19, 2011 (Photo: Jack Gregg)
This week another round of extremely high tides will hit the California coast, providing a glimpse of what the state can expect as sea levels continue to rise. These “king tides” will roll in from February 16th through the 18th, with the highest swells expected on the morning of the 17th, between 7:30 and 9 a.m.
A consortium of environmental groups is again calling for help documenting these high tides. The San Francisco Bay National Estuarine Reserve (NERR), which is spearheading the local effort, has set up a Flickr site where members of public can share their photos. Organizers launched the site last month, in time for the king tides in January, and since then more than 80 photos have been uploaded by dozens of contributors. Continue reading
Imagine 45 days of rain brought by a series of winter storms so strong and wet that they turned the Sacramento Valley into an inland sea, making the state capital virtually inaccessible.
Well, that happened in California in the winter of 1861-1862, and scientists say it will happen again, bringing massive flooding, landslides and property damage across the state.
To help emergency agencies plan for such an event, the US Geological Survey released the “ARkStorm Scenario” in Sacramento this week, detailing the repercussions of a storm that produces up to ten feet of rain and forces the evacuations of more than a million people.
“Vast floods would basically take out all the farm land,” said Marcia McNutt, director of the USGS. “They would destroy homes, animals would die, roads would be impassable, infrastructure would be rendered unusable, dikes would fail, levees, would fail.”
Scientists created this hypothetical storm by combining two actual storms, one from 1969 and one from 1986, and putting them back to back. Together, they rival the 1860’s storm in magnitude, which was the last time California saw a storm this size.
Pacific ocean conditions that often portend a dry winter sure haven’t so far.
Scientists like to joke that “climate is what you expect, weather is what you get.” The relatively soggy winter so far is a classic example of that.

A closely-watched oscillation in the Pacific is in the La Niña phase this winter, creating colder-than-normal surface temperatures and distorting weather patterns. Usually a La Niña means drier-than-normal conditions for Southern California in particular and often for northern parts of the state as well. Not this year–at least not so far. The rain set multiple records over the weekend. Los Angeles has had a third of its average annual rainfall in a week. So what’s going on? Continue reading
A chilly summer suddenly switches to record-breaking heat in much of California. Is this climate change?
Photo: Craig Miller
It reached 113 degrees in Los Angeles on Monday, a record. And while a string of hot days in California doesn’t signify climate change any more than do record snowstorms in Washington D.C., the summer of 2010 did set quite a few records for high temperatures and heat waves. Although for us here in California, this week notwithstanding, we’ve had a pretty cool summer.
But this week’s heat — especially in Southern California — is a reminder of the ripple effects that could become commonplace if predictions of more frequent and severe heat waves come to pass, with a changing climate. Utilities pleaded with customers to conserve power as temperatures triggered record spikes in the electricity load and subsequent strain on the electrical grid. Continue reading

The heat wave in Russia has captured international media attention, breaking temperature records left and right (see figure below). It has also captured the attention of commodity traders. In a typical year Russia produces about as much wheat as the United States, and is among the top exporters of wheat flour in the world. But this year, wheat has been decimated in the areas around Moscow, with yield expected to be 30 percent or so below normal. This week Russia announced they are banning all exports of wheat from August 15 through the end of the year. Since late June, wheat prices on the Chicago Board of Trade have risen by 50 percent, to more than $7 a bushel.

Preventing injuries is one of the easiest (and most obvious) ways to protect your health and ensure successful aging. Let's look at some of the major physical factors that can help you prevent injury.
Poor vision increases the risk of injury. Our eyesight changes as we get older, often resulting in a weakened ability to see things clearly. Poor night vision, sensitivity to glare, and a diminished sense of depth perception are all part of normal aging. So get your vision checked regularly. Make sure you don't have conditions such as glaucoma and cataracts; if you do, get them treated. If you wear glasses, get them checked for effectiveness.
Hearing is another ability that can diminish with age. Because hearing loss can also make you less aware of dangers (for example, sirens, cars honking, smoke alarms), it's important to have your hearing checked regularly and to properly maintain and use hearing aids if you need them.
The ability to understand and relate clearly to our environment is key to personal safety. If a senior displays signs of dementia, family members and caregivers need to help prevent accidents by ensuring that the person lives in a safe place. Modern dementia care facilities are designed to allow freedom and safety for seniors at risk. Seniors living at home require the same safety precautions.
Health and Medication
Some medications can cause drowsiness, blurred vision, dizziness, and muscle relaxation, all conditions that can lead to injury. Always consult with the doctor about possible side effects and interactions with over-the-counter medications. It's safer for seniors to be awake and aware.
Exercises suitable for seniors, even the frail elderly, can help develop better muscle tone to improve balance and gait. | <urn:uuid:a2fbce0e-95a3-4656-b2ac-07191b0667b0> | CC-MAIN-2019-30 | https://www.urmc.rochester.edu/senior-health/aging/preventing-injury.aspx | s3://commoncrawl/crawl-data/CC-MAIN-2019-30/segments/1563195525046.5/warc/CC-MAIN-20190717041500-20190717063500-00545.warc.gz | en | 0.940673 | 355 | 3.15625 | 3 |

Chinese Tallowtree - Triadica sebifera
Common Name: Chinese Tallowtree
Scientific Name: Triadica sebifera
Chinese tallowtree is a small to medium sized deciduous tree in the Euphorbiaceae (Spurge) family. It is monoecious, producing male and female flowers on the same plant. As with many species in the Euphorbia family, tallowtree is toxic to animals and humans. The white sap may be a skin irritant. It is native to China and Japan where the waxy outer covering of the seed it is used for machine oil, soap making, fuel oil, and many other uses.
Height: Chinese tallowtree can reach a height of 15 meters at maturity.
Leaves: The leaves are rhombic ovate, 4 to 7 cm long and 3.5 to 6 cm wide. The tip of the leaf is acuminate (pointed) with a rounded to truncate (flattened) base. The leaf surface is glabrous with smooth margins and prominent venation. The leaf stalks are 2-5 cm long with two prominent glands just below the leaf. Leaves are placed alternately on the stem.
Flowers: The terminal flowers are in greenish-yellow spike-like bundles. The staminate (male) flowers occur in fascicles of 3-15 on the upper portion of the flower. The solitary pistillate (female) flowers are on pedicels at the base of the spike.
Fruit: The 1 to 1.3 cm capsule has three locules (compartments) turning from green to black upon maturity. The capsule walls are eventually shed exposing the seeds.
Seeds: The three seeds per capsule are round, white, and 7 to 8 mm in size.
Growth initiates in early spring and flowers are produced from March through May. Flowering can begin when the trees are one meter tall, which may be as early as three years of age depending on growing conditions. The male and female seed clusters mature at different times. Variation is seen between sub-populations as to which type matures first. This contributes to the high genetic diversity of this species. The seeds mature in late summer to fall. Seeds are produced annually and each tree has the potential of bearing 100,000 seeds. Trees remain productive throughout their lives, which is commonly up to 25 years, although trees of 100 years of age have been recorded. Distribution of seed is primarily due to birds and water. Trees readily resprout from stumps and rootstocks.
Origin and Distribution
Chinese tallowtree is native to China and Japan. It was introduced into the United States in the 1700’s in South Carolina. It was distributed in the Gulf Coast in the 1900’s by the U.S. Department of Agriculture in an attempt to establish a soap making industry. Current distribution includes all of the Southeastern United States from Texas to Florida, North Carolina to Arkansas, and it was recently discovered in California.
Chinese tallowtree resembles several species of poplar (Populus sp,) trees. The main distinguishing feature is that tallowtree has smooth margins on the leaves while poplars are serrated.
Tallowtree prefers mesic to hydric soils but it can tolerate a wide range of soil conditions. It is commonly found in bottomlands, old fields, coastal prairies, and riparian areas. It can become established in shaded areas and is capable of spreading into undisturbed, as well as, disturbed areas. It is tolerant of periodic flooding and exposure to saltwater.
Cutting: Cut trees at ground level with power or manual saws. Cutting is most effective when trees have begun to flower to prevent seed production. Because tallowtree spreads by suckering, resprouts are common after treatment. Cutting is an initial control measure and will require either an herbicidal control or repeated cutting for resprouts.
Girdling: Use this method on large trees where the use of herbicides is impractical. Using a hatchet, make a cut through the bark encircling the base of the tree, approximately 15 cm (6 in) above the ground. Be sure that the cut goes well into or below the cambium layer. This method will kill the top of the tree but resprouts are common. Follow-up treatments for many years may be required until roots are exhausted, so this method is not recommended for large populations.
Hand Pulling: Chinese tallowtree is effectively controlled by manual removal of young seedlings. Plants should be pulled as soon as they are large enough to grasp, but before they produce seeds. Seedlings are best pulled after a rain when the soil is loose. The entire root must be removed since broken fragments may resprout.
Foliar Spray Method: This method should be considered for large thickets of tallowtree seedlings where risk to non-target species is minimal. Air temperature should be above 65°F to ensure absorption of herbicides.
Glyphosate: Apply a 2% solution of glyphosate and water plus a 0.5% non-ionic surfactant to thoroughly wet all leaves. Use a low pressure and coarse spray pattern to reduce spray drift damage to non-target species. Glyphosate is a non-selective systemic herbicide that may kill non-target partially sprayed plants.
Triclopyr: Apply a 2% solution of triclopyr and water plus a 0.5% non-ionic surfactant to thoroughly wet all leaves. Use a low-pressure coarse spray pattern to reduce spray drift damage to non-target species. Triclopyr is a selective herbicide for broadleaf species. In areas where desirable grasses are growing under or around tallowtree, triclopyr can be used without non-target damage.
Cut Stump Method: This control method should be considered when treating individual trees or where the presence of desirable species precludes foliar application. Stump treatments can be used as long as the ground is not frozen.
Glyphosate: Horizontally cut stems at or near ground level. Immediately apply a 50% solution of glyphosate and water to the cut stump, covering the outer 20% of the stump.
Triclopyr: Horizontally cut stems at or near ground level. Immediately apply a 50% solution of triclopyr and water to the cut stump, covering the outer 20% of the stump.
Basal Bark Method: This method is effective throughout the year as long as the ground is not frozen. Apply a mixture of 25% triclopyr ester and 75% horticultural oil to the basal parts of the tree to a height of 30-38 cm (12-15 in) from the ground. Thorough wetting is necessary for good control; spray until run-off is noticeable at the ground line.
Although no biological controls are currently available, in 2000 the U. S. Department of Agriculture reported that the potential for biological control for tallowtree is promising. This was concluded after several species of insects were observed feeding on the leaves, flowers and seeds in natural stands of tallowtree in China.

The Sutter Buttes of Northern California’s Sacramento Valley are where life began and where life ends. Playing a role in the traditional creation and afterlife stories of the Maidu and Wintun peoples, this small mountain range was a place of ritual for their ancestors, who once lived within view of the Buttes. In the 19th century, European settlement and the imposition of private property rights severed the Native American way of life — but it is the concept of private property rights that today both preserves the Buttes and leaves them precariously open to development. Presently the Buttes are mostly in private hands, and the grasslands and oak-studded hills are kept primarily as cattle and sheep ranches with strictly limited public access. However, in recent years land in the Sutter Buttes has been subdivided into residential lots, and conservation advocates and Native American leaders fear that the future of the Buttes could include more development. Arlene Ward, a member of the Mechoopda Maidu tribal council, says: “The Gold Rush and the events of the 1800s stripped us of our cultural identity and our resources. We lost who we were. Now in the 21st century, many people are taking up their identity as native peoples. The Sutter Buttes are significant to who we are and it may be that there are practices we want to revive and we will want to go to that power place — but it has to be there for us.”
The Land and Its People
The Maidu Indians who lived east of the Buttes called them Histum Yani, and the Wintun Indians, who lived to the west, knew them as Onolai-tol. Both names translate to “Middle Mountain.” Rising like an island in the center of the Sacramento Valley, the Sutter Buttes figure prominently in the creation stories of these two Native American tribes. The origin stories differ: sometimes the Sutter Buttes arose out of water or darkness or chaos, created by the falcon spirit animal. In other stories, the Buttes were where Earth Maker dwelled after having made the world.
But just as the Sutter Buttes have a place at the beginning of creation, they also play a vital role at the end of life. In many native traditions, the Buttes are a mysterious, powerful portal to the spirit world, a stopping point for the dead on their journey to the afterlife. In some traditions, the Buttes are so powerful and holy that stepping foot in them is forbidden except to healers and spiritual leaders.
Northern California native peoples, such as those belonging to the Maidu and Wintun nations, did not live within the Sutter Buttes but seasonally traveled to the foothills to gather acorns, hunt and perform rituals and ceremonies. Their home villages were along the Sacramento and Feather rivers, where the Buttes’ prominent peaks dominated the people’s spiritual and visual landscape.
Oak trees dot the grassy slopes of these ancient, eroded volcanic domes, which culminate in a rough circle of steep, craggy spires — the highest peak tops 2,100 feet. The Sutter Buttes are approximately 10 miles across, with a total footprint of 75 square miles, about 1.5 times the size of San Francisco.
The mountain’s plant and animal community is similar to those found in the foothills of the Coast Range to the west and in the Sierra Nevada to the east. But for thousands of years, the Sutter Buttes have been separated from these regions by 40 miles of grasslands, a separation that has created an “island effect.” Although there are no plants or animals endemic to the Sutter Buttes, over millennia this separation created a unique biological community. The Buttes are where some plants and animals have their most northerly extension of their range, while others their most southerly.
In the 1830s a malaria epidemic brought by European fur trappers killed an estimated two thirds of the area’s native population; later diseases such as smallpox and cholera killed even more. The California Gold Rush displaced ancestral villages when the establishment of towns pushed the few remaining Indians onto remote village sites. When California joined the United States in 1850, the state passed legislation allowing for Native Americas to be forced into “apprenticeships.” These events devastated what was once the densest population of native people in America. Finally, in 1862, many Sacramento Valley Indians were forcibly relocated to a reservation. Today, the closest Native American settlement is a Wintun “Rancheria,” or tribal land, about 10 miles west of the Buttes.
Despite the devastation and displacement, the Sutter Buttes continued to be an important part of Native American mythology. The Sacramento Valley native peoples had long performed sacred dances, some of which are traced back to visions of dancing animals and spirits in the Sutter Buttes. In the 1870s, the California Ghost Dance synthesized with the Wintun’s Hesi ceremonies into the Big Head dance, in which participants danced for restoration of their Indian way of life. The Big Head dance is still performed today as a dance of renewal.
By the late 19th century, the Central Valley’s rich agricultural land was primarily cultivated in wheat. Today the once vast grasslands have been converted to rice fields, while the oak woodlands are now orchards for walnuts, prunes and peaches. Sheep primarily grazed the upland of the Sutter Buttes until cattle production took hold about 50 years ago.
Current Challenges and Preservation Efforts
Future development and land-use strategies in the Sutter Buttes are the main concern of conservationists and Native American communities, who want to see the Buttes preserved and not sold for housing development or resorts.
About a dozen families own the majority of land in the Sutter Buttes, much of which is still used as ranchland. Most of the private landowners in the Sutter Buttes have a family relationship with the land that spans more than 100 years. They are proud of their ranching heritage and their private stewardship of the land and want to see it remain undeveloped. The California Parks Department owns a 1,785-acre parcel of land on the mountain’s northern flank; this undeveloped park is currently closed to the public due to state budget shortfalls.
While land in the Sutter Buttes is zoned as agricultural, the current Sutter County land-use plan allows for the land to be divided into lots as small as 20 acres. Critics of the current zoning contend that this opens the door for luxury residential construction that could gradually erase the natural landscape and spiritual nature of the Buttes. That’s what happened in 1999, when 1,100 acres in the foothills of the Sutter Buttes were sold and subdivided into 11 large lots. Five luxury homes have been built on those lots since then. In total, there are around 30 subdivided lots that cover approximately 2,500 acres.
In 2007, Sutter County approved the division of 900 acres of Sutter Buttes foothills into 13 lots. A local organization, the Yuba Historical Society, sued the county and the developer on the basis that there was no environmental impact report completed and that an illegal road variance was granted that could open up development anywhere within the Buttes. The lawsuit was settled in January 2010, with Sutter County setting aside its 2007 approval of the land’s division.
Sutter County is currently revamping its General Plan, including zoning designations in the Sutter Buttes. The plan will not be adopted until late 2010, but draft proposals point toward zoning restrictions that will keep any subdivided lots to 80 acres or greater. Such changes would prevent development of dense subdivisions, but would still allow for construction of luxury homes on large lots, such as those built in 1999. Even with changes to zoning, those who advocate preserving agricultural and undeveloped land in the Buttes worry that zoning designations could become vulnerable with each election cycle as local government leadership changes.
One strategy for land preservation is to protect land through conservation easements. The Middle Mountain Foundation is a land trust that actively purchases development rights from willing landowners through conservation easements in the Sutter Buttes; it then holds these easements in perpetuity as a protection against development. The foundation currently owns about 200 acres in the Sutter Buttes and plans to purchase 1,800 more acres through conservation easements.
For the time being, however, the current downturn in California’s economy and real estate market has eased development pressure. Depressed housing sales, stricter housing loan guidelines, and cautious investors all combine to protect the Buttes, at least for now, from aggressive real estate development.
When the housing market recovers, however, the Buttes may attract new real estate development because of revised Federal Emergency Management Agency flood maps. These maps, which go into effect at the end of 2011, place most of Sutter County in a flood zone, a designation that is projected to quadruple home insurance premiums. The Sutter Buttes are not part of the new flood zone, which may lure homebuyers and developers seeking to avoid the sharply increased insurance premiums.
Though members of the Maidu and Wintun communities now mostly live far away from the Sutter Buttes, they are nevertheless involved in the issues there. In 2005, members of the Mechoopda Maidu Indian tribe testified before the state’s park commission, asking that the parkland in the Sutter Buttes be granted a name that reflected the Native American heritage. (To date, the park has been temporarily designated as Sutter Buttes State Park.) They also requested that it be designated as a cultural reserve, a request that has not been realized.
Within the native community, however, there are differing opinions on the Sutter Buttes. Some feel strongly that there should be little to no human presence there, while others hike into the interior Buttes as guides on hiking trips that directly support conservation efforts. Since 1976 close to 40,000 adults and school children have visited the Buttes on such guide-led public tours.
What You Can Do
The only way the public can gain access into the Sutter Buttes is to join several guided hiking tours that are offered in cooperation with landowners and the state park system on a limited, for-fee basis by the Yuba Historical Society and the Middle Mountain Foundation. Monies collected support their land preservation activities. You can also support the work of these organizations by becoming a member.

November 1, 2018. The article discusses the low level of Latinx and Hispanic political representation, despite the growth of this population. The article highlights that although small, there has been a slight increase in Hispanic/Latinx representation to 10 percent of both state legislative and congressional seats from less than 5 percent of state representatives and 6 percent of federal elected officials in 1996. The author argues that there should be almost double as many Hispanic/Latinx elected officials based on their share of the population.
Given that there has also been an increase this year in deportation raidsagainst immigrants and a policy of separating thousandsof migrant children from their families, Latino New Yorkers may feel politically marginalized.
New York has never had a governor, lieutenant governor, U.S. senator, attorney general or comptroller who is Latino. Likewise, New York City has never had a Latino mayor, comptroller or public advocate. “We still have a long way to go,” said Assemblyman Marcos Crespo, chairman of the Assembly’s Puerto Rican/Hispanic Task Force.
“Hispanics are underrepresented at basically every level of government,” said David Kallick, director of the Immigration Research Initiative at the Fiscal Policy Institute. While any immigrant or ethnic group gains a greater political presence as its population grows, Kallick said, Latinos and other communities of color face additional racial discrimination that has made it harder for them to gain full representation compared to previous newcomers, such as the Irish or Italians.

Diagnosing Plant Diseases of Floricultural Crops
An accurate diagnosis of disease is important for successful implementation of an IPM program. Different pathogens are controlled by different fungicide chemistries. Bacterial diseases are not controlled with fungicides, and some bacterial diseases are easily mistaken for fungal diseases. Some fungicides have a narrow spectrum of activity. Abiotic factors such as high soluble salts, nutrient imbalances, or chemcial injury can mimic the symptoms of plant pathogens. In addition, if you know the disease, you can usually find information regarding the environmental conditions necessary for disease development. You could also find out if the pathogen is seed-borne, soil-borne, and whether other crops in the greenhouse are susceptible.
The ability to make an accurate diagnosis on-site is dependent on a disease that has unique symptoms. Also, the grower needs to have previously identified the problem, or have a good illustration or written description. There are a number of diseases that can be easily identified on-site, and there are many that can only be diagnosed in a lab. If you are a Massachusetts commercial flower grower and are unsure of the cause of symptoms, you can send a specimen to the UMass Extension Plant Diagnostic Lab.
Damping-off and Root Rots. Of all of the diseases, damping-off and root rot are the most difficult to identify on-site. Pythium and Rhizoctonia are the two most common causes, but they usually do not leave any clues as to their identity. Also, they have a wide host range, so the plant they occur on does not supply a clue. When Rhizoctonia is causing web blight, you can see the brown strands of mycelium on the diseased plants. Webbing occurs when temperature and humidity are high. There are test kits available that can allow you to make an accurate on-site identification of Pythium, Phytophthora and Rhizoctonia.
Soft-Rots. Cuttings have a large wound on the base and can be very susceptible to Erwinia soft rot, especially when temperatures are in the 90's and there is plenty of water. When Erwinia is the cause, the base of the cuttings become soft and slimy. If the cuttings are diseased but remain firm, there is another cause.
Poinsettias are subject to a rapidly developing soft rot by the fungi Rhizopus, Choenephora, and the bacterium Erwinia. These can be difficult or impossible to identify on-site; however there are no effective fungicides or bactericides. Simply discard the plants.

Bacterial Blight of Geranium. Bacterial blight of geranium is caused by Xanthomonas campestris pv. pelargoni. Wilted plants will not have root rot or stem canker (unless there are several diseases occurring). At first, one or two leaves will become soft and droop. Root rot or high soluble salts can also cause wilt but usually the whole plant wilts. Another good indication of X. c pv. pelargoni is leaf spots, but they do not always occur. Ralstonia (Pseudomonas) solanacearum can also cause a systemic wilt of geranium but does not cause leaf spots. We rarely see Ralstonia in geranium in New England but we had several cases in 1999, 2002 and 2004. Ralstonia solanacearum Race 3, Biovar 2 is a federally quarantined pest (USDA-APHIS) and Massachusetts Department of Agricultural Resources (MDAR) must be contacted and a rigorous eradication program undertaken. X. c pv. pelargoni only infects geranium but Ralstonia infects a variety of ornamentals and vegetables including potato and tomato (as well as tobacco and banana).
Bacterial Leaf Spots. Bacterial leaf spots can look very similar to fungal leaf spots but when you hold them up to the light (as if to see the light through the leaf), bacterial spots may have a translucent look to them. On geraniums, you may see a yellow halo around the spots. Bacterial spots on impatiens can be distinguished from Alternaria leaf spot because Alternaria causes the leaf to become yellow. Pseudomonas syringae and P. cichorii cause leaf spots on geranium, chrysanthemum, and many other ornamental plants. Affected leaves do not wilt.
Photos, UMass and UConn Photo Library
Fungal Leaf Spots and Blights. There are many fungi that cause leaf spotting of floricultural crops. With experience, some can be recognized but most cannot be identified on-site. Alternaria on zinnia (photo), impatiens and Gomphrena is relatively easy to identify. Botrytis (photo) is easy to identify when it is producing its gray crop of spores. On Fuchsia (photo), Botrytis causes cankers which usually do not develop spores, but cankers on Fuchsia are almost always caused by Botrytis.
Powdery Mildew. (Photo) This disease is easy to identify because of the white to gray, powdery crop of spores it produces on the leaf surface. In most cases, powdery mildew develops on the top side of the leaf but on poinsettia and a few other plants, mildew will also grow on the bottom. African violet, Begonia, Dahlia, Gerbera, Hydrangea, Kalanchoe and pansy, commonly develop powdery mildew. On Kalanchoe, powdery mildew can be difficult to recognize because only a fine webbing will develop. Powdery mildews are host specific and spread only to closely related plant hosts.
Downy Mildews are becoming more prevalent in ornamental crops, particularly basil (photo), coleus, and snapdragon, and are difficult to identify without a microscope. Symptoms can be mistaken for nutrient imbalances or bacterial diseases. Symptoms occur on leaf undersides where the fungus sporulates as a fuzzy, white or gray to purplish growth. These fungi are relatives of Pythium and Phytophthora and are managed by different fungicides than other leaf-spotting fungi.
Rusts. Like powdery mildew, rust diseases are easy to identify. The rust fungi produce pustules of spores on the bottom side of the leaf. The pustules contain masses of rusty to orange colored spores. Snapdragon (photo), Fuchsia, carnation and geranium are susceptible to rust diseases.
Fusarium and Verticillium Wilt. Diseases caused by these fungi initially affect only one side of the plant. Foliage on the affected stems will wilt and usually become yellow. There may or may not be discoloration in the vascular tissue (cutting into the stem will reveal a dark stain). It is difficult to diagnose these diseases with much confidence in the field. With cyclamen, several leaves will turn yellow. When you cut through the corm (cut the top off) you will see a dark band of vascular tissue that corresponds to the location of the yellowed leaves. These two vascular wilt fungi are not commonly seen in greenhouses. When they do occur, it is usually on chrysanthemum (photo), cyclamen or basil.
Foliar Nematodes. These nematodes are likely to have been introduced into the greenhouse on cuttings. They produce different symptoms depending on the host. On Begonia, leaves can take on a reddish coloration before developing dry patches. On chrysanthemum, foliar nematodes produce distinct black lesions that are bordered by the leaf veins. African violets may form necrotic patches on the bottom of the leaves, and newly developing leaves can be distorted. The foliage of Easter lily becomes twisted.
Photo of foliar nematodes on Heuchera.
Viruses. Virus diseases can be very distinctive, or on the other hand, impossible to recognize. The most common virus in greenhouses is Impatiens Necrotic Spot Virus (INSV). While not all plants are hosts, the host list is at least 500 species long. The symptoms vary considerably from plant to plant but once you can recognize INSV on a specific plant you can usually identify it the next time it occurs on the same host. Very reliable test kits that are easy to use are available for testing INSV on-site.
Photo of INSV on New Guinea Impatiens
Other viruses can produce distinct symptoms but for the most part, cannot be reliably diagnosed outside of the lab. Viruses should be identified accurately because they are carried by different insect vectors, and have different host ranges.

operetta ŏpərĕt´ə [key], type of light opera with a frivolous, sentimental story, often employing parody and satire and containing both spoken dialogue and much light, pleasant music. In the early 19th-century opéras comiques of Boieldieu, Auber, and Adolphe Adam, there was a growing tendency toward sophistication, preparing the way for Offenbach, who during the French Second Empire created the operetta. The distinction between the operetta and the lighter examples of opéra comique that immediately preceded it is hard to draw; in general the opéra comique makes some appeal to the sentiments, while the French operetta attempts only to amuse. The Viennese operetta, dating from c.1870, did not have the excellent librettists that the French enjoyed; the operettas of Johann Strauss the younger suffered from this defect. Those of Suppé owe much of their virtue to Offenbach's influence. Less distinguished are the products of the early 20th cent., represented by the works of Franz Lehár and Oscar Straus. The immortal operettas of W. S. Gilbert and Sir Arthur Sullivan were to London of the 1880s what Offenbach's works had been to Paris 20 years earlier. The noteworthy composers in American operetta are Victor Herbert and Reginald de Koven. After World War I operettas gradually gave way to musical comedies (see musicals ).

- The words that express some sudden feelings or emotions are called interjection. It is not a part of speech because it does n`t enter into the structure of a sentence. It stands independently.
Interjection may express:
1. Joy: [Hurrah! Huzzah! Wao! ]
2. Grief: [Alas! Ah! Oh!]
3. Surprise: [Ha! What! Well!]
4. Approval: [Bravo! Great! Well done! ]
5. Order: [Hold! Quick! Ready!]
1. Hello! What are you doing here?
2. Alas! My friend has died.
3. Hurrah! We have won the match.
4. Oh! I got such a surprise.
5. Hush! Don`t say a word.
Certain groups of words are also used as interjections;
1. Ah me!
2. For shame!
3. Good heavens!
4. Good gracious!
Some adjectives are also used as interjections;
1. Great! You have done a good job.
2. Nice! You played well.
3. Good! We can use it.
4. Sweet! It looks so cute.
Some nouns are also used as interjections;
1. Congratulations! You have passed the exam.
2. Man! What have you done?
The following parts of speech are sometimes used as interjections;
Noun: A horse! A horse! My dukedom for a horse!
Verb: would it were eternal spring!
Adverb: How nice of you to come!
Conjunction: If only I were young again!
Infinitive: To think of him as a friend! | <urn:uuid:e869a13a-e241-4c39-88f3-3a9af6743eb2> | CC-MAIN-2023-14 | https://lessonplancoaches.com/lesson-no-19-interjection-subject-english-grade-10th/ | s3://commoncrawl/crawl-data/CC-MAIN-2023-14/segments/1679296949533.16/warc/CC-MAIN-20230331020535-20230331050535-00772.warc.gz | en | 0.940464 | 386 | 3.390625 | 3 |
More people than ever are living with HIV in the UK and each year new infections occur.
People living with HIV in the UK
- The number of people living with HIV in the UK has trebled in the last 10 years
- More than 90,000 people are living with HIV in the UK
- Over a quarter of people with HIV in the UK are undiagnosed
- About two thirds of people living with HIV are men and a third are women
- Over half of all people living with HIV are aged between 30 and 44, but there are significant numbers both of young people and older people now living with HIV
- One in 20 gay men in the UK is living with HIV
New HIV cases in 2008
- 7,298 new diagnoses
- The two groups most affected remain gay and bisexual men and black African heterosexuals. Three-quarters of people diagnosed were among these two groups.
- 2,760 new diagnoses among men who have sex with men
- 2,790 new diagnoses among people from black and minority ethnic communities
I have to admit there have been times that I have gone for my regular checks that I have been worried that I might have been at real risk of being infected. Indeed one of my recent tests I was anxious. I had experienced the primary HIV infection (or sero-conversion illness) symptoms, at about the right time scale when I could have been exposed. However, my tests did come back negative.
Knowing your status is important whether you are gay or straight especially if you are engaging in an active sex life with multiple partners, or if you are in an open relationship. Get into the habit of going regularly (every six months) to your local genitourinary medicine (GUM) clinic or with your local GP. The local GUM clinic for me now is up at the Royal Victoria Hospital, their staff there carried out my last test.
The message today is:
Be as Safe as you can be
Be Responsible for you own health
The term living with HIV often only refers to those who actually have HIV. But a friend of mine recently said that those of use who know a family member, friend or partner who has HIV are also in a sense living with HIV. We deal with some of the effects it has on the person that we love. If we carry on living with their HIV we do not love them any less, we may show our love for them even more through the practical things we do for them and the support we give them to help them carry on as normal.
In that sense I am someone who is living with another friend's HIV and I want them to know that I am thinking of them as ever today. | <urn:uuid:b91f2959-39a8-498f-8c7e-03d4d7a8119a> | CC-MAIN-2017-22 | http://stephensliberaljournal.blogspot.com/2010/12/world-aids-day-actaware.html | s3://commoncrawl/crawl-data/CC-MAIN-2017-22/segments/1495463615105.83/warc/CC-MAIN-20170530124450-20170530144450-00256.warc.gz | en | 0.978027 | 553 | 2.59375 | 3 |
Depression and bipolar disorders are mental disorders, real physical illnesses that affect a person’s moods, thoughts, body, energy and emotions. Both disorders, especially bipolar disorder, tend to follow a cyclical course, meaning they have ups and downs. Nearly one in five American adults, or 43.7 million people, experienced a diagnosable mental illness in 2012 according to the Substance Abuse and Mental Health Services Administration (SAMHSA).
Treatment for these illnesses can also have ups and downs. As much as we may want it to, wellness often does not happen overnight. It is normal to wish you could feel better faster or to worry that you will never feel better. However, know that you can feel better, and that ultimately you are in charge of your wellness. There are many things you can do to help yourself.
Talk to your health care provider (HCP) about what you need from treatment. Your HCP can provide the treatment(s) and/or medication(s) that work best for you. Along the way, you have a right to ask questions about the treatments you are getting and choose the treatments you want.

Three schools are expanding drone-related education programs thanks to grants from NASA’s Minority University Research and Education Program (MUREP) Aerospace Academy (MAA), which has selected seven minority-serving institutions (MSIs) for cooperative agreement awards.
The grants will be used to build the interest, skills and knowledge necessary for K-12 students to pursue science, technology, engineering, and mathematics (STEM) careers, explains NASA. These selections are designed to increase the participation and retention of historically underserved and underrepresented youth in grades K-12 through hands-on STEM activities. Awardees will receive up to $325,000 for a two-year period.
Elizabeth City State University (ECSU) will conduct a comprehensive outreach program for K-12 education in rural northeastern North Carolina. ECSU will adopt a grade-appropriate NASA curriculum to enhance authentic and experiential learning experiences through the integration of 3D printing technology, virtual reality simulation, unmanned aerial vehicle (UAV) design, mobile robotics, computer programming and sensor-based measurement systems. The project will extend learning to local school districts through the use of a mobile aerospace education lab. This collaborative project is expected to directly impact at least 1,450 students.
Tennessee State University (TSU) will create a STEM curriculum based on three thematic modules, each containing problem-based learning methods with hands-on instructional strategies. The program will capitalize on the NASA Aerospace Education Laboratory, which provides a flight simulator, inflatable planetarium, drones, robotics, Ozmo Coding, immersive virtual reality technology, and a computer lab with NASA software. The project will expand its reach by increasing capacity through a strategic partnership with elementary and middle schools from the Metropolitan Nashville Public School District.
Navajo Technical University (NTU) proposes to develop a robotics academy in partnership with the newly established Bond Wilson Center for Technologies in Kirtland, N.M. This new partnership provides high school students from tribal reservation communities with classes in aerospace manufacturing, unmanned aircraft systems (UAS), conceptual design and planning, and employee skills development. NTU will partner with Southwestern Indian Polytechnic Institute’s training faculty and interns at their year-round robotics center to leverage existing NASA projects. The university also will develop an experiential learning robotics syllabus that is respectful to traditional Navajo culture and transportable to other tribal-serving institutions. | <urn:uuid:2ac7c8f8-e39c-4959-bf53-003acac09bef> | CC-MAIN-2019-39 | https://unmanned-aerial.com/nasa-funding-expands-uas-programs-at-minority-serving-institutions | s3://commoncrawl/crawl-data/CC-MAIN-2019-39/segments/1568514575596.77/warc/CC-MAIN-20190922160018-20190922182018-00355.warc.gz | en | 0.904186 | 486 | 2.640625 | 3 |
The use of any animal species (including birds, reptiles, and domesticated species) in any entertainment, travelling or otherwise, should be submitted to scientific and ethological consideration.
The use of wild mammals, especially elephants, big cats (lions and tigers) in travelling circuses1 reflects a traditional, but outdated, view of wild animals. These animals have the same genetic makeup as their counterparts in the wild and retain their natural instinctive behavioural drives and needs. The needs of non-domesticated, wild mammals cannot be met within a travelling circus; especially in terms of housing and being able to express normal behaviours.
There is little or no educational, conservational, research or economic benefit derived from the use of wild mammals in travelling circuses that might justify their use. In addition to the welfare considerations, the use of wild mammals in circuses can represent serious animal health and public health and safety risks23 . These wild mammals can cause physical injury to the public and their keepers and zoonotic disease transmission4 . Public polls5 show that an overwhelming majority of the public backs a ban on wild animals performing in circuses. | <urn:uuid:827c5990-312b-484b-b11f-6d9209f24db3> | CC-MAIN-2023-50 | https://uevp.fve.org/working_documents/the-use-of-animals-in-travelling-circuses/ | s3://commoncrawl/crawl-data/CC-MAIN-2023-50/segments/1700679100518.73/warc/CC-MAIN-20231203225036-20231204015036-00310.warc.gz | en | 0.917402 | 230 | 3.03125 | 3 |

Archaeological finds from Cardiff University’s excavations at a south Wales site will be on show to members of the public during half term (26-30 October 2009).Visitors to Cosmeston Medieval Village in Penarth will be able to see some of the artefacts recovered during an excavation of the remains of a medieval manor house at the site.Earlier this year a team of archaeologists from the University worked alongside community volunteers to discover more about the manor house, known as Cosmeston Castle, and its relationship with the surrounding area.
Their excavations revealed substantial features of the manor house and an interesting range of artefacts. The finds will help inform the team about how people may have lived and worked at Cosmeston. It will also help shape future investigations at the site.Specific artefacts recovered during the dig include a fragment of a slate ‘Nine Men’s Morris’ board game, a bone gaming counter, medieval metal dress fastenings, a wide range of pottery dating from the 12th century onwards, including vessel fragments and cooking pots, glass fragments and artefacts, animal bone and sea shells.Jane Stewart, Community Archaeologist at the University and project officer for the Cosmeston excavations said: "Visitors to Cosmeston during half term will be able to see medieval pottery - some of it more than 700 years old - and other artefacts from the summer dig being washed and packed ready for transport to the University. It’s an opportunity for people find out about local history and to learn about the past through hands-on activities."The archaeology team will be on site at Cosmeston between 11am-3pm daily. The event is free and takes place in the Village museum. Tickets for tours of the Medieval Village are available from the park Visitor Centre.
1. Cardiff School of History and ArchaeologyThe School of History and Archaeology carries out teaching and research in four main areas: History and Welsh History; Ancient History; Archaeology; and Archaeology Conservation.History and Welsh History offers a broad survey of the main aspects from the medieval period to the twentieth century. Areas of expertise include: Medieval England, the Crusades, military religious orders; early modern England and Wales; early modern Spain; and modern Indian historiography and gender history. The broad area of Europe and the British Empire in the Twentieth Century encompasses such research themes as: modern Germany; biological racism and ethics; the Right in France; and the Wilson era in British politics. Areas of expertise in Welsh history include early modern Wales; the gentry; industrialisation; popular culture and Welsh emigration/dispersal (with particular reference to North America)Ancient History focuses on the social and economic history of the ancient world, with particular emphasis on: warrior elites; warfare and the formation; organisation and social effects of armies; violence and its control inside ancient societies; issues of identity, especially gender history and ethnicity; and slavery and other systems of labour and land exploitation.Archaeology offers expertise in two main areas: the archaeology of Britain, Europe and the Mediterranean 5000BC-1000AD; and studies in ancient technology and the analysis of materials and conservation science.The Archaeology Conservation degree scheme offered by the School is one of only two such undergraduate courses in Britain. It attracts conservation commissions from throughout the UK, giving students valuable hands-on experience. The teaching of Ancient History and Archaeology was assessed as "Excellent" in the recent national assessment of teaching quality in UK universities.2. Cardiff UniversityCardiff University is recognised in independent government assessments as one of Britain’s leading teaching and research universities and is a member of the Russell Group of the UK’s most research intensive universities. Among its academic staff are two Nobel Laureates, including the winner of the 2007 Nobel Prize for Medicine, Professor Sir Martin Evans. Founded by Royal Charter in 1883, today the University combines impressive modern facilities and a dynamic approach to teaching and research. The University’s breadth of expertise in research and research-led teaching encompasses: the humanities; the natural, physical, health, life and social sciences; engineering and technology; preparation for a wide range of professions; and a longstanding commitment to lifelong learning.Visit the University website at: www.cardiff.ac.uk

AbstractHabitat loss and fragmentation is a common conservation threat in the United States. Land in urban areas is at a premium for biodiversity preservation and historic landmarks and cemeteries are green spaces that undergo limited disturbance. Historic and sacred sites, such as those designated by historical markers and listed as cemeteries often contain remnant old growth trees, native species and potentially rare or endangered flora. Old growth trees are often considered a ‘keystone structure’, providing resources that are crucial for other species and/or a ‘foundational species’, essential in forest ecosystems providing food and shelter for wildlife. These mature trees are more prone to environmental factors such as competition with invasive plants, climatic extremes, air pollution, disease/pets and habitat fragmentation, therefore it is crucial to evaluate these historical places to assess their ecosystem service roles. A rapid decline of old foundational trees will have major impacts on the ecosystem services reported in this study. Using a citizen science survey approach and the iNaturalist smartphone app, as well as i-Tree Eco software, we surveyed trees at cemeteries and various historical places in Clinton County, NY. Tree species, diameter at breast height, tree height, percent crown dieback, as well as signs of disease, and woodpecker damage were recorded. The survey found that the most common tree species were Picea abies (Norway spruce), Robinia pseudoacacia (black locust), and Picea pungens (blue spruce). Black locust sequesters the most carbon ≈ (525 kg/yr), while Norway spruce reduces runoff (≈75 m3). Annually, mature foundational trees combined annually removed ≈ 57.03 kg ($870/yr) of pollution, stored ≈ 148.7 tons ($21,300) of carbon, ≈ sequestered 1.302 tons ($186.00/yr) of carbon, and produced ≈ 3.472 tons of oxygen. Locally, Riverside Cemetery annually sequestered the most carbon (0.4 tons), produced ≈ 1.2 tons of oxygen, and stored ≈ 1.5 tons of CO2, followed by Gilliland Cemetery. Interestingly, Gilliland Cemetery was found to be a monoculture of the invasive species black locust; more research could provide insight as to ecosystem functioning prior to the invasion. Further research is needed to help provide a stronger ecological value to these historical and sacred spaces. | <urn:uuid:a715aa74-59f6-4422-b9ac-06629f7fc55d> | CC-MAIN-2023-23 | https://soar.suny.edu/handle/20.500.12648/886 | s3://commoncrawl/crawl-data/CC-MAIN-2023-23/segments/1685224648465.70/warc/CC-MAIN-20230602072202-20230602102202-00789.warc.gz | en | 0.932925 | 627 | 2.84375 | 3 |

How to Learn Python in 2022?
There is no doubt that Python is one of the most popular programming languages today. With this programming language being preferred in emerging fields like artificial intelligence, data science, and machine learning, its popularity is unlikely to slow down any time soon. Python is loved by software engineers and tech enthusiasts for how versatile and customizable this programming language is. It not only is easy to learn but also offers clean syntax. Therefore, whether you are a beginner or someone with existing knowledge of programming, learning Python can be simple.
Python can be used to build any type of application that you may want as per your requirements. Operating Python is this simple and fun. In 2022, one cannot afford to miss out on something like this which has a plethora of benefits. In this article, we describe some easy ways to get started with learning Python and taking a small step into the world of programming.
1. Online courses
Unless you have been living under a rock, you would know that learning has had a major shift to an online mode. Now, you have several online websites offering online certification courses on any subject or topic of your choice and various educational tech tools at your disposal. For learning Python, you can select any of these apps and get started right away. Some of the popular platforms that offer online Python courses include Coursera, Udemy, edX, etc. Furthermore, one can also check out YouTube for resources and content on learning Python quickly.
2. Practice is the key
Learning Python does not only involve watching online videos and reading books - being consistent with practicing what you learn is the way to go about it. It is always advisable to cover the basics first and then get into the more complex part. The basic topics that you may consider while learning Python include loops, conditional statements, and variables among others. Additionally, you can get into the habit of participating in online coding challenges from time to time and taking topic-wise quizzes. This will help you learn the language better and faster and also make you see the shortcomings that you can work on.
However, we understand it may be a little overwhelming for students to learn Python as they are already burdened with academic tasks and deadlines. Students looking to manage their core subjects alongside learning Python can ask experts to "do my essay for money" and order essays online from a reliable service. This will help them keep up with their day-to-day assignments and also give them the time to learn a programming language.
3. Take up projects
When you are done learning the basics and practicing coding daily for some time, you may be ready to start working on projects to implement what you have learned. These projects will test your knowledge and also help you build a portfolio to show to potential recruiters when you wish to take up jobs in the field. A good portfolio may help you get a full-time or part-time job or an internship.
When the world is moving towards digital transformation at such a fast pace, one needs to know about the technology and programming languages. It not only increases your employability but also enhances your problem-solving ability. Python being one of the most popular languages for its versatility in today’s time, it is the most sought-after among students. Our tips can help you learn Python effortlessly and make the process seem less challenging.

Throughout central Africa, from south of the Sahara to north of the Kalahari deserts.
Bushbucks can be found throughout their broad distribution wherever there is adequate cover for concealment, nearly irrespective of altitude or aridity. They live in forest edges or brushy cover associated with rivers and streams. During the night they move out of their home thicket to somewhat more open areas to feed.
Male bushbucks are bigger than females, with weights ranging from 40 to 80 kg and shoulder heights from 70 to 100 cm. Females weigh about 25 to 60 kg and are 65 to 85 cm tall. Only males have horns, which usually spiral once and are fairly straight, parallel to one another, and up to a half meter long. Females are usually a lighter brown than males. Both sexes have white spots and stripes, the patterns of which vary geographically.
Young can be born at any time of year, but in arid regions there is a peak in birth rates during the rainy season. Gestation requires only 180 days, allowing a female to produce more than one calf per year. A single calf weighing about 4 kg is born. The calf does not follow its mother out into the open to forage until it is four months old. It remains hidden in the dense underbrush in the mean time, and its mother returns periodically to let it nurse. Sexual maturity is reached at one year, but males' horns do not reach full size until three years of age.
Bushbuck are the least social of the African antelopes. They are often seen singly, although sometimes small groups of females and their respective young are found. Bushbuck are not territorial, and except for disputes over females in estrus they are not aggressive toward one another, so in areas with good quality habitat there may be several animals in close proximity. Therefore the traditional designation of them as "solitary" is somewhat misleading. These antelope are mainly nocturnal, although they may also be active at dusk and/or dawn. The daytime is spent concealed from predators (which include virtually all carnivores their size or larger) in dense, bushy cover of the type that is usually found near rivers. They come out at night to feed in more open areas, but never venture far from some type of cover. Bushbuck are very capable swimmers.
Bushbucks are browsers. They eat herbs and the leaves, twigs, and flowers of a large number of plant species. Although they will eat a wide variety of plant species when hungry, they are somewhat selective when possible, prefering knobbly creeper and sausage tree. They will also occasionally eat fresh grass.
These antelopes have been hunted as a food source.
Bushbucks cause or are involved in a number of problems. Perhaps most seriously, their populations are controlled in areas near domestic cattle. Since bushbuck live among the trees and shrubs associated with rivers, they are frequently bitten by tsetse flies, which could then infect the cattle with nagana (sleeping sickness). Bushbuck cause damage in pine forestry areas by nibbling the tops of the young trees, resulting in excessive branching. Also, they frequently live on the outskirts of towns and cities, and in these areas they damage peoples' gardens.
There are no special conservation efforts for this species. They are able to coexist with human habitation to a greater extent than many other species, and in some areas they are considered a pest and their population is controlled.

Order: Blattoidae Family: Blattidae
Just to say that word makes one
shudder. Cockroaches multiply like crazy and quickly infest whole buildings traveling along networks of
pipes from place to place. Cockroaches are ancient insects that hail from the
Devonian period of the Paleozoic era that took place over 400 million years ago. They have
changed very little during their evolution. Worldwide there are more than 3,600 species
with around 60 residing in the USA. Of the 60 there are specifically 5 roaches that are
most troublesome in the USA which we will list for you here. Their preferred habitats are
human occupied dwellings, animal burrows, mines, caves, termite and ant nests. They
also like decaying organic matter such as we find on the floor of forests. A
little known and disgusting fact is that cockroaches can live minus their
head for 9 days before the body finally starves to death.
Oriental Roach: Body length to 1 1/4 inch being dark reddish brown to
black. Oriental cockroaches do not have the sticky pads on their feet
that other cockroaches do have. They are unable to climb smooth
surfaces. Egg cases hold up to 16 eggs. Cases are placed in sheltered
areas with garbage or food so it is often found in kitchen areas. Eggs
hatch in about 6-8 weeks. The adults live can live up to a year. Females
are wingless whereas the males have wings. Infestation areas
include: beneath washers, refrigerators and sinks. Also in sewers, drains, basements,
cracks and crevices of porches and
- American Roach: These are 1 /34 inch long with the main body being
reddish brown in color and a pale banded marking behind the head on the edge of the
thorax. They lay brown egg cases that will turn black with 14 eggs. The
eggs hatch in 38 to 49 days. Food storage and food preparation areas in
restaurants, grocery stores, bakeries, and houses, are often infested..
The males and females both have wings and are avid fliers compared to
- German Roach: To 9/16 an inch in length with a light brown body and 2
darker stripes on the thorax. The cases contain from 30 to 48 eggs and
take about 30 days to hatch.
Females carry cases until 12 days before hatching. At that time they are dropped just
about anywhere. The German cockroach produces more eggs and has more
generations per year (three to four) than other roaches. The German roach is the most common of the roach pests.
They have a high need for moisture, usually traveling 10 to 12 feet from
their abode for food and water in kitchens, bathrooms, laundry rooms,
etc. They prefer darkness.
- Smokybrown Roach: Big guys up to 1 1/2 inch in length with body being
solid black or dark brown. Egg cases have 20 eggs that mature into adults within 320-388
days. Egg case is dropped after 24 hours hatching in 24 to 70 days. Smokybrown is mainly
found in the southwestern states and the Gulf area. Lives outside in debris and woodpiles.
It can also get into garages.
Brownbanded Roach: 9/16 in length with body color being
and subtle light color v-shaped bands found on the wings. Egg cases contain 16 eggs. Adult
stage is reached in approximately 5 months. This roach will "glue" it's egg
cases in dark places like under furniture, closets and also on ceilings.
Roaches will eat just about anything when hungry
enough but their preferred diet consists of carbohydrate based substances including
pastes, glues, solid soaps and starch based paints and foods like pasta.
Using an Integrated Pest Management plan, cockroach activity can be
monitored using sticky traps or glue boards. These monitoring stations are
placed throughout a building where roaches are likely to be found such as in
dark places along cabinets, walls, under appliances, on pipes, etc., in
bathrooms and kitchens. Any tight cracks about 3/8 inch or smaller are good
cockroach habitats. Monitoring indicates whether roaches are present and if
control practices are working. The following
tips and methods may be tried on any of these roaches.
- Sugar and Baking Soda: This
excellent cockroach treatment comes from Christopher Moss who resides in Prescott,
Arizona. He says this worked on the smaller Oriental type of cockroaches that tend to
infest cabinets. Prior to coming up with this recipe Christopher had used the commercial
type sprays that you can find at supermarkets to no avail. Boric acid bates did not work
either. Our many thanks to Christopher for this!
- Here it is. Just mix 50/50 granulated sugar and baking soda (Arm & Hammer will do)
and place it in their path. Takes about 3 or 4 days to notice a reduction and 2 weeks
later, no roaches. The cure seems relatively permanent, although you may have to repeat
some months later.
Why might this work?
The roach has an acid stomach. They can't resist the sugar and the baking soda mixes with
the acid in their stomachs. Blamo! The best part is the roach is a cannibal and they eat
their dead, and the whole process cascades through the colony.
- Cook 'em with steam! Roaches also

Over 4 million people visited Independence Hall in 2004. Nearly 600,000 visited Martin Luther King Jr.'s childhood home. And about 350,000 visited the Little Bighorn Battlefield. They went not just to learn history, but to feel the power of place and experience the deeper understanding that comes from standing exactly where historical figures have stood, soaking in the sights, sounds, and scents of the environment.
To help teachers (and parents) expose children to the power of place, there is a beautiful new series of books, American Landmarks. Here, as a small taste of the series, we share the introduction by Editor James Oliver Horton, as well as excerpts from two of the books, Landmarks of the American Revolution and Landmarks of African-American History.
By James Oliver Horton
Few experiences can connect us with our past more completely than walking the ground where our history happened. The landmarks of American history have a vital role to play in helping us to understand our past because they are its physical evidence. The sensory experience of a place can help us reconstruct historical events, just as archaeologists reconstruct vanished civilizations. It can also inspire us to empathize with those who came before us. As philosophers of the Crow Indian nation have reminded us, "The ground on which we stand is sacred ground. It is the blood of our ancestors." It is the history owed to our children. They will remember that history only to the extent that we preserve the places where it was made.
Historical sites are some of history's best teachers. In the early 1970s, when I was a graduate student working on a study of the 19th-century black community in Boston, I walked the streets of Beacon Hill imagining the daily lives of those who lived there a century before. Although I had learned much about the people of that community from their newspapers, pamphlets, personal letters, and official records, nothing put me in touch with their lives like standing in the places where they had stood and exploring the neighborhood where they lived.
I remember walking along Myrtle Street just down Beacon Hill from the rear of the Massachusetts State House in the early morning and realizing that Leonard Grimes, the black minister of the Fugitive Slave Church, must have squinted into the sun just as I was doing as he emerged from his home at the rear of number 59 and turned left on his way to his church. Walking up Joy Street in December added new meaning to descriptions I had read about the sound of children sledding down its slope during the particularly snowy winter of 1850. And twisting my ankle on irregular cobblestone streets made clear the precarious footing for fugitive slaves fleeing at full run from slave catchers empowered by the Fugitive Slave Law of 1850.
Any historical event is much better understood within the context of its historical setting. It is one thing to read the details of the Battle of Gettysburg. It is quite another to stand on Little Round Top, with its commanding view of the battlefield to the north and west, and contemplate the assault of the 15th Alabama Confederates against the downhill charge of the 20th Maine Volunteer Infantry. Standing at the summit, taking the measure of the degree of slope and the open area that afforded little cover to advancing armies, is an unforgettable experience. It bears irrefutable testimony to the horror of that battle and to the sacrifice of the more than 50,000 men during four days in the summer of 1863.
The American Landmarks series has emerged from this belief in the power of place to move us and teach us. It was with this philosophy in mind that in 1966 Congress authorized the establishment of the National Register of Historic Places, "the nation's official list of cultural resources worthy of preservation." These enduring symbols of the American experience are as diverse as the immigration station on Angel Island in San Francisco Bay, which served as the U.S. entry point for thousands of Asian immigrants; or Sinclair Lewis's boyhood home in Sauk Centre, Minn., the place that inspired the novelist's Nobel Prize–winning descriptions of small-town America; or the Cape Canaveral Air Force Station in Florida, launch site of Neil Armstrong's historic trip to the moon. Together, such places define us as a nation.
The historic sites in this series are selected from the National Register and the books are written by some of our nation's finest historians—based at universities, historic museums, and historic sites. For them, historic sites are not just places to visit on a field trip, but primary sources that inform their scholarship. Not simply illustrations of history, they bring the reality of our past to life, making it meaningful to our present and useful for our future.
How to Use This Series
The American Landmarks series is designed to tell the story of American history from a unique perspective: the places where history was made. In every book, each chapter profiles a historic site listed on the National Register of Historic Places, and each site is used as the centerpiece for discussion of a particular aspect of history—for example, the Woolworth store in the Downtown Greensboro Historic District for Martin Luther King Jr.'s role in the civil rights movement. This series is not intended as an architectural history; it is an American history.
In each book, there is a regional map of the United States locating the main sites covered in the volume. Each chapter contains a main essay that explains the site's historical importance; a fact box (explained next); and one or two maps that locate the site in the region or show its main features. Each chapter also contains a box listing sites related to the main subject. For each related site, the box includes the official name, address, phone number, Web site, whether it is a National Historic Landmark or part of the National Parks Service, and a short description. As much as possible, the related sites are geographically diverse and open to the public.
Many of the chapters feature primary sources such as letters, journal entries, legal documents, and newspaper articles. Each primary source is introduced by an explanatory note or a caption.
In the back of each book is a timeline of important events mentioned in the text, along with a few other major events that help give a chronological context for the book's theme. A list of further reading includes site-specific reading, along with general reading pertinent to the book.
Each chapter has a fact box containing reference information for its main site. This box includes a picture of the site; the site's official name on the National Register; contact information; National Register Information System number (which you can you use to obtain more details about the site); whether the site is a National Historic Landmark or part of the National Park Service; and important dates, people, and events in the site's history.

Oxford University Press partnered with the National Park Service, the National Register of Historic Places, the National Park Foundation, and the Gilder Lehrman Institute of American History to develop the American Landmarks series. The complete series is listed below. Currently, four of the books—on the American Revolution, the Civil War, women's history, and African-American history—are available. The rest will be published over the next few years. The books are $30 each, but until December 31, 2005, AFT members can receive a 20 percent discount by calling Oxford University Press at (800) 451-7556 and mentioning the promotional code 24848.

Vincent van Gogh Mental Illness Creates Masterpieces
Van Gogh Self Portrait
Vincent van Gogh was born on March 30, 1853 in Zundert, Netherlands. He came from a
family of clergymen, art-dealers, and military officers. A servant who worked for the
Van Gogh family when Vincent was a child described him as odd, aloof, and having queer
manners. At the age 16, Vincent became an apprentice at an art dealer located at The
Hague, in Belgium. At the age 20, he was transferred to the London gallery.
In London van Gogh became a teacher. He fell in love with an English girl who rejected
him. Sometimes students at the school would taunt Vincent Van Gogh, calling him a queer
and a freak. He was unhappy as a teacher, so he decided to satisfy his father's wish
that he become a minister. He entered an evangelical school in Brussels and in 1879
he became a preacher southwestern Belgium.
In 1886, Van Gogh moved to Paris to live with his brother Theo who worked as an
art-dealer. Theo introduced him to several popular painters of the time, including
Camille Pissarro, Georges Seurat, and Paul Gaugin.
In 1888, Van Gogh persuaded Gaugin to come to Arles in southern France to live with
him in a house he had set up as an art studio. They spent the autumn painting together.
This is when Van Gogh painted his famous Sun Flowers series.
The relationship of Van Gogh and Gaugin was filled with conflict. On Christmas Eve
of 1888 Van Gogh and Gaugin had a violent argument. In letters to his brother, Theo,
Van Gogh hinted that in the argument Gaugin cut off part of Van Gogh's left ear. But
the official story is that Van Gogh cut off a part of his own ear.
Thought to be mentally ill, Van Gogh was committed to the asylum in St. Remy. He
continued to paint for the 12 months while he was under medical supervision in the
asylum. He was treated by the well-known doctor, Paul-Ferdinand Gachet. Dr. Gachet
dignosed Van Gogh was as having mental disorders, including schizophrenia, bipolar
disorder, neurosis, and alcohol poisoning.
In the 19th century digitalis, extracted from the purple foxglove plant, was the
main treatment for these disorders. The side effects of digitalis treatment is vision
problems similar to viewing the world through a yellow filter, along with glare and
colored halos. Dr. Gachet has been charged with mishandling van Gogh’s care by administering
excessive doses of digitalis.
After having failed at being a teacher, a minister, and an art dealer, at the age of 27,
Van Gogh's incredible artistic talent was beginning to show. Between November 1881 and
July 1890 he worked at a feverish pace, creating almost 900 paintings. Van Gogh's
most famous paintings are Starry Night, Sunflowers, Irises, Poppies, Blossoming Almond
Tree, The Mulberry Tree, and The Potato Eaters.
A study of Van Gogh's work shows that he expressed his internal state of mind in his
artwork. When he was in a happy optimistic mood, his work would be bright and bold,
one example being his painting Seascape at Saintes-Maries. When he was depressed his
work became dark and somber, one example being his painting The Potato Eaters. | <urn:uuid:20b55703-900d-449c-aab5-5298d1df8059> | CC-MAIN-2018-22 | http://bucarotechelp.com/howto/88041801.asp | s3://commoncrawl/crawl-data/CC-MAIN-2018-22/segments/1526794869272.81/warc/CC-MAIN-20180527151021-20180527171021-00104.warc.gz | en | 0.980607 | 765 | 3.296875 | 3 |
Cluj Infant Feeding Study – breastfeeding attitudes, knowledge and behaviors among mothers in Cluj county, Romania
With evidence suggesting that breastfeeding rates are dropping, there is an immediate need to collect empirical data at both national and local levels on breastfeeding initiation, duration, and exclusivity. Subjects were 18 years and older and were recruited into two cohorts: (1) third-trimester pregnant women (n=336) and (2) mothers within 24 hours of delivery capable of initiating breastfeeding (n=276). Fifty-two of the women in the second cohort who initiated breastfeeding in the hospital were followed at 6-10 weeks post-partum. Subjects completed questionnaires that included demographic information; previous, actual and intended infant feeding methods; attitudes about breastfeeding in public; and the IIFAS-R, a psychometrically validated Romanian version of the 17-item Iowa Infant Feeding Attitude Scale.

Deaf Awareness Week runs from the 21st to the 27th of September this year. Deaf Awareness Week has been running since 2004, and this year’s theme is ‘Tender Ears’, focusing on the risks that can lead to hearing loss in childhood and during life.
Hearing impairment affects 450,000 New Zealanders. According to the National Foundation for the Deaf, 48,000 hearing aids were fitted last year, and this year that number has gone up to 55,000 (this figure represents total fittings and may include replacements). Based on an Australian study, hearing loss is estimated to cost about 1.67% of the GDP which translates to $3 billion/per year in New Zealand. Hearing loss costs the ACC $90 million in claims to date, and that figure is increasing at about 20% per annum (you can read more about hearing loss in the workplace here). A survey from the National Foundation for the Deaf which examined 65 early childhood centres concluded that about 20% of children have been affected by high noise levels. (*Data provided by the National Foundation for the Deaf)
What is noise induced hearing loss?
Noise induces damage to the sensory hair cells in the inner ear (cochlea). These cells, which are responsible for translating sound into an electrical signal that is transmitted to the brain, have a bundle of ‘hairs’ which vibrate in response to sound. Loud noises damage these hairs, and render the cells unable to transmit information to the brain. In humans (as in other mammals), once these cells are damaged they cannot be repaired and ultimately die. This means that any damage to the hair cells may result in permanent hearing loss.

- In 1990 the University of Auckland established the first Audiology programme.
- Hair cells can regenerate in birds and other non-mammalian vertebrates.

Archeologists and historians have long debated how medieval artists could create patterns of such amazing complexity while providing a balanced work over large areas. Now, using computer technology and other modern tools, the two scientists may have cracked the secret.
Peter Lu, of Harvard University, first became fascinated with Islamic decorative motifs when he visited an old school in Bukhara, Uzbekistan.
Lu was struck by the beauty and technical complexity of a blue wall pattern featuring 10-pointed stars. Being a scientist -- a physics graduate student -- he sought a precise answer as to why this composition appealed to his aesthetic senses.
Mathematicians often talk about the "beauty" or "elegance" of complicated mathematical formulas, meaning their balance and symmetry. That is an idea most people have to accept on trust, as we know too little about higher mathematics to judge for ourselves.
But what if the artists of the Islamic world five centuries or more ago knew the secrets of advanced geometry and used this tool of logic to create designs of such elegance that they lead the spirit to tranquility?
Much of the development of traditional Islamic patterns is shrouded in mystery, as the artists of centuries ago rarely revealed their techniques to others. After his experience at the madrasah, however, Lu went out of his way to consult a rare 15th-century scroll that contained example patterns. He began to comprehend the basic puzzle pieces, made up of five geometrical shapes.
Lu eventually found decorations above an archway at the Darb-i Imam shrine at Isfahan, in central Iran, which fitted an advanced mathematical formula based on a crystalline structure. Turning his thoughts to the blue Uzbek pattern that had so impressed him, he was also reminded of a crystal.
Lu tells RFE/RL that his previous studies of crystalline forms predisposed him to be interested in patterns.
"Fortune favors the prepared mind," Lu says. "Mainly it just aroused some interesting suspicions more than anything else about the geometry that might have been used. I guess I would say that I was very much predisposed to thinking about those tilings in that particular way because of my undergraduate work with Professor Steinhardt."
Paul Steinhardt is the eminent physicist who invented the mathematical term "quasicrystal." He is the Albert Einstein Professor of Science at Princeton University. He is noted for his thoughts on big themes, having proposed among other things an alternative to the Big Bang theory on the creation of the universe.
Lu and Steinhardt worked together on the quasicrystalline properties of Islamic design, using computers to identify the elements of design.
Steinhardt tells RFE/RL there is evidence of a connection: "We have shown on the designs that they had discovered the elements needed to construct such designs, and they had a particularly spectacular example -- the one at the Darb-i Imam shrine."
Lu expresses amazement, saying Western mathematicians have only established the principles of quasicrystalline geometry in the last 20 or 30 years.
But both scientists caution that more research is necessary to establish whether the old artists were working intuitively or had a conscious grasp of the mathematical principles involved.
They have written a joint paper on their findings that appeared in the authoritative journal "Science" on February 27.
In part, it says that on the basis of their studies on medieval art and decorations, they "suggest that by 1200 [of the Christian era] there was an important breakthrough in Islamic mathematics and design." That was "the discovery of an entirely new way to conceptualize and construct girih line patterns."
Girih lines are the outlines creating a pattern -- originally limited to relatively simple geometric star and polygon patterns. But the use of tiles and advances in math between the 12th and 15th centuries allowed the creation of increasingly complex girih line patterns, which can continue infinitely without repeating themselves.
"The indications are that they somehow realized that," Steinhardt says. "And once they realized that, there began a series of more and more complex patterns, all based on putting together the same elements, but in more and more complex ways."
In the course of the research, Lu either visited or studied photographs of buildings in Iran, Afghanistan, Iraq, and Turkey, as well as Uzbekistan. His greatest enthusiasm is reserved for what he saw in Uzbekistan.
"The architecture is fantastic," Lu says. "That was of course the thing that struck me in Bukhara and Samarkand, because Samarkand in particular was the capital of the Timur dynasty; and the types of patterns that I had been working on, it turned out, had their pinnacle in terms of sophistication and complexity around that time and in those places."
The research done by the two scholars is arousing renewed interest in the fascinating world of Islamic pattern art forms.

As we celebrate Dr. Martin Luther King Jr’s Day, let’s honor the power of his rhetoric and his movement by focusing on the five reasons his “I Have a Dream Speech” became history-changing.
First: King’s life was consistent with his rhetoric. He did what he encouraged others to do. Surrounded by threats, bullied by hecklers and racist law officers, he endured arrest, followed Gandhi’s example of nonviolence, and ultimately gave his life in the advancement of civil rights.
Second: The speech still resonates because of King’s vivid illustrations. We “have come to our nation’s Capitol to cash a check,” he said. Yet the nation’s response to promises of justice was marked “insufficient funds.” Even so, he said “We refuse to believe that the bank of justice is bankrupt.”
Third: Dr. King used catchy, attention-riveting words. Grand example: noting that Negroes were stranded on “a lonely island of poverty in the midst of a vast ocean of material prosperity.”
Fourth: King spoke with stirring emotion. His pulsating emotion emerged naturally from his genuinely intense belief in his message. In the magic of the moment, he departed from his prepared text to speak directly from his heart.
Fifth: He sustained magnetism because his message was consistent. He allowed no room for partial, delayed solutions to segregation. Compromise was not in his vocabulary as a leader.
Yes, because Dr. Martin Luther King, Jr lived the message he spoke, used vivid illustrations, coined creative words and phrases, spoke with obviously genuine emotion, and stuck to a consistent, unwavering theme, commemorating his “I Have a Dream” speech is more than justifiable—it is morally imperative.

Changes in government spending and taxes can help bring the economy to full employment. When the government increases its spending or decreases taxes, its budget balance declines. These are referred to as transfer payments. They channelized these economics in four categories i.
If this is the case, then these imports do not represent demand for goods produced in this country. According to the Economic Report of the President, over the past 46 years, total government spending on goods and services, as well as federal spending by itself, has fallen as a percentage of GDP while state and local spending has increased as a percentage of GDP.
He also argued that the government could alleviate the unemployment by increasing demand through either increases in government spending or decreases in taxes.
At each round, income decreases because of decreases in both consumption expenditures and government expenditures.

Our Courage. Jews in Europe 1945-48
31 March - 30 September 2022
From Białystok via Frankfurt to Amsterdam, from Berlin via Budapest to Bari: The
exhibition “Our Courage” is the first project of its kind to present the diversity of Jewish experience in the early post-war period from a pan-European, transnational perspective. The exhibition was conceived at the Jewish Museum Frankfurt and can be seen as a second station at the Documentation Centre.
The Destruction of Jewish Europe
Before the Shoah, Europe was the most important continent for Jewish life, and the
beginning of the exhibition calls this to mind. By 1945, continental Jewish culture had been irrevocably destroyed. For many survivors, the end of the war meant continued flight and migration. Some tried to return to their Eastern European homeland and found not surviving relatives there, but hostile neighbours who had helped themselves to their belongings. Many fled further west to the Displaced Persons Camps of the US military. For the most part, their
goal was to make their way to British Mandatory Palestine or the US.
In the period immediately following the war, the situation Jews found themselves in
varied widely. It depended not only on where and how they’d survived World War II, or which unit or partisan group they’d fought in, or where they had fled to. It was also crucial how many relatives and friends were still alive, whom they happened to encounter, and what help they received. The location they tried to settle in temporarily or permanently also played a key role.
The exhibition conveys this range of different circumstances survivors lived in between Eastern and Western Europe; its title recalls a Yiddish partisan song from 1943 as well as the name of the newspaper of the DP camp in Zeilsheim near Frankfurt. The exhibition space features seven installations portraying cities and counties in Europe.
Frankfurt am Main or (East) Berlin can be found alongside cities lesser known here, such
as Białystok in Poland, where more than half of the population was Jewish before World War II, the transit city of Bari in southern Italy, and the region around the Lower Silesian municipality of Dzierżoniów, which became a focus of Jewish hope in Poland for a few years following 1945. Films, photographs, portraits, and personal objects convey a sensual impression of these locations, while autobiographical texts, read by actors of the Schauspiel Frankfurt ensemble, bring to life Jewish perspectives in these places shortly after surviving the war.
Europe as a Place of Escape
From this period of flight across Europe, various material testimonies from these
locations have been preserved in private and public collections. They speak of the search for relatives, the existential misery of the survivors and refugees, the first attempts at documenting and commemorating the mass extermination, as well as efforts to reconnect with pre-war culture and to revive Jewish traditions. And they tell of people’s efforts to leave the continent of Europe behind. Together, these testimonies confirm that Jewish survivors and refugees were not passive victims, but took their lives into their own hands and had an active part in shaping them.
Art and the Public
The years immediately following the war saw a noticeable number of graphic works and
artist books on the Shoah being published. Together with their number, the choice of these forms of publication, which by their very nature are aimed at a broader public, shows that the artists wanted to bear witness to a wider audience and contribute to the social discourse on the genocide of European Jews.
Theater and Literature
The numerous temporary theater ensembles, especially in the Displaced Persons Camps in the American-occupied zones, were for the most part aimed at the refugee community
itself. They sought to find images, sounds, language, and emotions for what had occurred. In addition, they addressed the present reality in the transit camps and shaped and discussed initial ideas for the future. The language used in these theatrical performances, like that of literature, was Yiddish. As a cultural expression and linguistic means of communication, it had become the only remaining homeland, which is also evidenced by the brisk pace of Yiddish
publication in Germany’s American sector, with more than one hundred different magazines and around thirty volumes of prose and poetry documented in the years following 1945.

The exhibition narrates up to the year 1948 and presents an opportunity for reflection on the new international order. In many respects, 1948 was a turning point in the post-war period as Europe became the playing field of the Cold War. The British mandate over Palestine ended in May. Resting on the decision of the newly established UN General Assembly to divide the region, David Ben-Gurion, Israel’s first prime minister, declared part of it to be the new independent State of Israel. In the years that followed, almost 400,000 Jewish refugees from Europe were admitted into the country. In December 1948, the UN General Assembly adopted the principles of a new, international definition of law: the Convention on the Prevention and Punishment of the Crime of Genocide and the Universal Declaration of Human Rights. Both were largely prepared by Jewish immigrants from Europe and drew lessons from the mass murder of European Jews. | <urn:uuid:39e68067-c389-4067-be9c-4cdd3da3c407> | CC-MAIN-2022-33 | https://www.flucht-vertreibung-versoehnung.de/en/visit/sonderausstellung | s3://commoncrawl/crawl-data/CC-MAIN-2022-33/segments/1659882571869.23/warc/CC-MAIN-20220813021048-20220813051048-00096.warc.gz | en | 0.966593 | 1,101 | 2.734375 | 3 |
Merry Christmas everyone! Hope this year you will have a Christmas filled with joy. This is the time of year when you decorate your house, buy gifts and invite your friends and family over for a Christmas dinner. The festival of Christmas is all about giving and sharing, no matter how little we have. The greatest gift you can give someone is the gift of happiness, and sustainability. You can really get creative and encourage others to become more environmentally conscious with green gifts. If we all could make this Christmas a Green Christmas, it would be the greatest gift we can give to the planet.
Every big effort starts with small steps, and although making our Christmas greener might seem like a small step, it could spiral into a big green movement if we all do our share of helping Mother Nature, by doing little things around the house that are eco-friendly. We could also influence others to walk on the eco-friendly path. Below are some ideas to make this Christmas a Green Christmas.
1. Buy Smart
Think eco-friendly when buying gifts. Buy items that are necessary, that fill practical needs. Buy smart and buy local. Gifts don’t have to be packaged with excessive wrapping paper to be a surprise. You will find several great green gift items that are useful, reduces wastage, and reduces environmental impact. A holiday trip, a reusable water bottle, or an energy saving appliance make excellent green gifts. Choose gifts made with recycled materials. Some companies will also make donations to conservation agencies or environmental funds if you purchase a gift from them. Find eco-friendly or organic alternatives to the gift items on your list.
2. Make your own gifts and decoration
Take some time and try to make some of your own Christmas decorations instead of buying them. Try reusing your old Christmas decoration materials, wrapping paper, calendars and gift bags. Making your own gifts makes it more personal and gives you a feeling of fulfillment. You are also able to use your imagination. Going green does not mean keeping the fun down. Use energy saving ideas such as LED lights to light up your house; they save up to 90% on energy consumption compared to conventional lights. Use natural, bio-degradable and eco-friendly items for decoration.
3. Recycle and reuse
The majority of all the Christmas trees bought during the Christmas holidays will end up in a landfill. Recycling trees instead of filling up landfill space would reduce a significant amount of environmental impact, and carbon emission associated with carrying and managing this waste. Buying a live Christmas tree in a planter will also allow you to plant it back after the holidays. Reuse packaging materials, cardboard boxes, wrapping paper, shopping bags and such as much as possible. Re-gifting or donating your old gifts to charities will also put your unwanted old items to good use. Find alternate ways to wrap gifts, such as using gift bags, instead of wrapping gifts with paper. Collect, separate and recycle all recyclable items from your house.
4. Connect with nature
Christmas is meant to be a family time and a wonderful time for giving back the gift of sustainability to Mother earth. This gives you an excellent opportunity to establish the ideas and values of sustainable living to your community, friends and family. Why not start a family tradition of an eco-friendly Christmas? Get out and connect with nature. Take your family on a trip in the wild. You can encourage outdoor activities with your children and in your community by engaging in activities such as nature hikes, planting trees, or other nature restoration activities.
The true holiday spirit is in giving and sharing. We have been using up resources from the planet for thousands of years. It’s time to give something back to Mother Nature. Be eco-friendly, reduce, reuse, and recycle and conserve in every way. Make this Christmas an opportunity for you to shift towards sustainability. Your Christmas can really be merry if you give the gift of sustainability to Mother Nature.
The green movement starts with you and we want all of you to join us on the green eco-friendly patch. We wish you all a Merry Christmas!
We would love to hear your own green ideas. Please share with us any ideas that you may have to make this planet greener.

Directions to the Nearest Alien Earth-like Planet: Walk from Here to Knight Library
Host: Jim Brau
Abstract: The landscape of exoplanet science has been dramatically reshaped since the launch of NASA’s Kepler mission in 2009. While the mission’s primary science driver was to uncover the frequency of Earth-like planets orbiting Sun-like stars, in fact the vast majority of rocky planets in their stellar habitable zones reside in very different environments. M dwarf stars, half the mass of the Sun and smaller, host most of the galaxy’s terrestrial worlds. The small stature of these stars, the most prolific type in the universe, render exoplanet detection and characterization easier for upcoming missions. However, they furnish very different conditions for life than have nourished it on Earth. I’ll summarize the key findings of what Kepler has revealed about planet occurrence, and how it informs our search for signatures of life on other planets. | <urn:uuid:1fdf82dd-74e4-43e7-870d-cd0e9dcf9d46> | CC-MAIN-2014-49 | http://physics.uoregon.edu/2014/05/01/may-8-colloquium/ | s3://commoncrawl/crawl-data/CC-MAIN-2014-49/segments/1416405337312.65/warc/CC-MAIN-20141119135537-00220-ip-10-235-23-156.ec2.internal.warc.gz | en | 0.911559 | 208 | 3.328125 | 3 |
Children living with violence in the home respond to their circumstances in many different ways. They may feel frightened, insecure and confused. Often, they learn to keep their feelings and fears to themselves – they may feel like the violence in their home life must be kept secret.
With support, children can begin to cope with and make sense of what has happened in their families. They can overcome the trauma or witnessing or experiencing violence and go on to live safe, happy lives.
We believe that no child should have to live with fear or abuse. We can signpost you onto the support you need to help rebuild your lives.
Effects of domestic violence on children
Many children do cope with and survive abuse, displaying extraordinary resilience. However, the physical, psychological and emotional effects of domestic violence on children can also be severe and long-lasting. Some children may become withdrawn and find it difficult to communicate. Others may blame themselves for the abuse. All children living with abuse are under stress. That stress may lead to any of the following:
- Aggression or bullying
- Problems in school, truancy, speech problems, difficulties with learning
- Attention seeking
- Nightmares or insomnia
- Anxiety, depression, fear of abandonment
- Feelings of inferiority
- Drug or alcohol abuse
- Eating disorders
- Constant colds, headaches, mouth ulcers, asthma, eczema
Many people think that a child who has experienced domestic violence will inevitably become a perpetrator or a victim of abuse later in life. This can happen, however there are a greater number of children who don’t perpetrate abuse than there is who do.
Growing up in a violent home is a risk factor and some children who experience abuse can go on to be abusive in future relationships. Most are repelled by the violence they received as they know only too well what damage it causes; therefore they are more prone to being passive rather than aggressive. | <urn:uuid:9d56637b-4e16-44fd-ab2a-c6458c6dacb8> | CC-MAIN-2020-16 | https://uberheroes.co.uk/parents-stuff/guides/domestic-violence/ | s3://commoncrawl/crawl-data/CC-MAIN-2020-16/segments/1585371807538.83/warc/CC-MAIN-20200408010207-20200408040707-00283.warc.gz | en | 0.96712 | 392 | 3.390625 | 3 |
Most people agree that presentation skills are important, but effective presentation skills are even more important. But how does one improve their presentation skills?
The first time I ever gave a presentation was my first week of university. It was in my college’s biggest lecture hall and in front of about 100 people. It was terrifying. There is no better way to describe it than that. My voice shook, my words stumbled and the palms of my hands greased.
It was a short, five minute presentation, though I have no idea how long I spoke for. It could have been a mere two minutes, or ten. I was just glad to get it over with and honestly didn’t care if I spoke well or not – as long as it was over.
It was times like then, and this is something I even still think about, that I wish I had the chance to practice my presentation skills at a younger age.
My first presentation was when I was 17 years old and my issues ultimately came down to a lack of experience which resulted in nerves and no confidence. Now, I see teachers from across the United States tweeting their students’ wonderful 30hands presentations, and these students are as young as kindergarteners.
I firmly believe that there is a direct correlation between effective presentation skills and confidence. How do you build confidence in a task? And how do you implement effective techniques to engage your audience longer?
It is a concept that has been put to design thinkers who agree that iterative prototyping positively affects self-efficacy towards a task (Dow and Klemmer, 2010). They say that for design thinkers, the “small wins” of iterative prototyping lead to greater confidence as the design process proceeds.
With 30hands Storyteller Web and 30hands Pro, it’s incredibly easy to be iterative thanks to easy edit features and narration tools. The narration tool in particular is a really cool feature for young learners to record their script, listen back, and make changes as they see fit. Actually listening to recordings of their own voices can help students spot mistakes, memorize information and develop their communication skills such as their intonation.
Communication skills and presentation skills also go hand-in-hand, with both traits having an impact on the other. Communication development is especially important in young learners.
Learning to communicate is key for children to interact with persons in their world and have their needs met (Gooden and Kearns, 2013). Communication skills for young learners include gaining the skills to understand and express thoughts, feelings and information.
By presenting with 30hands, learners of all ages and levels are developing their speech and writing skills as well as their vocabulary. It also helps them spread their ideas so to make a large impact.
This is not only done through words, but body language. For instance, Gihan Aboueleish of ICF International says that 90 percent of our personal communication calls for involvement.
Looking at people for five to ten seconds before looking away shows involvement.
Presentations can help students learn this type of engagement through practice, and these skills will benefit their school work too as well as provide them with valuable life skills.
A child who is good at communicating verbally will also find it easier to produce written communications, and thus will likely perform better in their school exams and written assignments (Kumon, 2016).
Students can also add 30hands presentations to their portfolios and share them with classmates, teachers and parents.
It’s incredibly easy to do this. All they have to do is publish their presentation as a video with either 30hands Web or 30hands Pro, and then share the link to whatever portfolio tool used by the school. The advantage of doing this is that the learners will be able to see their progress in one place, as will teachers and parents.
We don’t expect perfect presentations on first try. In fact, we don’t ever expect perfect presentations. But improvement through iteration is something we strongly believe in, and portfolios can act as strong evidence for this.
Learners will make mistakes, as does everyone.
It was Vincent Van Gogh that once said: “Even the knowledge of my own fallibility cannot keep me from making mistakes. Only when I fall do I get up again.”
Presentations can act as evidence of all those times students fell down and got right back up again, strengthening their confidence, communication and presentation skills in the process.
Happy presenting… and iterating!

Last month, amid escalating trade tensions, the World Trade Organization lowered its forecasts for global trade growth in 2019 to 1.2% (down from its April prediction of 2.6%) which would make it the slowest expansion in global trade since the financial crisis of 2008-09. Much of this slowdown can be attributed to heightened policy uncertainty, suggests new research.
In a study published by the World Bank, Cristina Constantinescu and others specifically find that a 1% increase in uncertainty can decrease goods and services trade growth by 0.02 percentage points. The increased uncertainty since 2018, they argue, could have reduced trade growth by a percentage point over last year.
To measure policy uncertainty, they used data from the Economic Policy Uncertainty indices of 18 countries over 24 years. In these indices, compiled by another group of researchers, uncertainty is measured by capturing the frequency of terms related to uncertainty and doubt that appear in each country's media outlets.
Economic policy uncertainty can lower trade growth in two ways, the study published by World Bank explains. First, in an uncertain environment, firms are likely to postpone investment decisions, consumers can cut back spending, and banks can increase the cost of finance. Second, policy uncertainty can affect trade volumes by influencing firms' decisions on whether to import inputs or invest in serving foreign markets.
The policy uncertainty also impacts global value chain (GVC)-related trade. This trade refers to the import or export of inputs as part of a production chain. As this requires larger upfront investments and is concentrated in capital-intensive sectors, policy uncertainty can affect these investment decisions. The authors find that, in the long run, GVC-related trade can be as sensitive to policy uncertainty as non-GVC related trade. | <urn:uuid:3e9a0bcd-a138-4c87-83f8-8c87ae882822> | CC-MAIN-2022-40 | https://www.tbsnews.net/economy/trade/whats-behind-slowdown-global-trade | s3://commoncrawl/crawl-data/CC-MAIN-2022-40/segments/1664030338001.99/warc/CC-MAIN-20221007080917-20221007110917-00154.warc.gz | en | 0.938056 | 354 | 2.640625 | 3 |
Data Analytics vs. Business Analytics
Data has transformed the world and is powering decision-making in industries. From higher institutions to tech firms, government agencies to non-profits, data has helped organisations to boost sales, launch new products and services, expand operations, and increase efficiency. This is the simple reason why organisations have embraced both data analytics and business analytics. While the two are often used interchangeably, there are significant differences. This article will make a comparison between data Analytics vs. business Analytics; relax and read further.
What is Data Analytics?
A data analyst focuses on collecting, analysing and processing data with the primary aim of getting insights that can help businesses and organisations grow. Data analytics can be carried out using:
- Machine Learning: This makes use of statistical probabilities to teach computers to process data more quickly.
- Predictive analytics: This helps aggregate and analyse historical data to help organisations make better-informed decisions.
- Data Mining: This involves examining and sorting large data sets to identify patterns, relationships and trends.
- Big data analytics: This brings everything together; it applies predictive analytics, machine learning, and data mining to transform data into business intelligence.
What is Business Analytics?
Business analytics is deeply about boosting efficiency and solving problems using managerial strategies, data-driven insights and effective communication. It’s all about utilising data to make practical, concrete decisions for an organisation.
There are three major types of business analytics. These include predictive analytics, prescriptive analytics and descriptive analytics. Descriptive analytics evaluates historical data for insights on a plan. Predictive analytics uses statistical techniques and machine learning to help businesses predict future events. Prescriptive analytics provides possible actions to take based on the outcomes of predictive and descriptive analytics.
Comparison between Business Analytics and Data Analytics
- Data source: For business analytics, the data sources are defined in advance based on the project goals. However, for data analytics, data sources are defined on the go as correlations are uncovered.
- Approach: Data analytics are typically more predictive and are majorly about answering questions to discover new insights to gain a competitive advantage. However, business analytics is more descriptive and retrospective. It largely involves defining goals and requirements for the project.
- Team members: Business analytics involves an analytics manager, data warehouse engineer, and business analyst. Data analytics simply requires a data analyst.
The reality is that every organisation, from new startups to already established global companies, needs to leverage data for business growth and innovation. Both data analytics and business analytics share the same goal of optimising data to solve problems and improve efficiency, but with a few fundamental differences.
Regardless of the path you choose as a company, you will need to collect relevant data from trusted sources fast and without stress. At Axual, we can help you speed up your analytics process to be able to make effective business decisions at the right time. You don’t need to go through any hassle as our team has several decades of experience with competence in data and business analytics. Let’s get started now!

Initial observations suggest that the terms “something” and “some thing” have only one significant difference: The first term is written as one word, while the latter is written as two words. While this is true, the more pertinent differences are how the two terms are properly used in writing.
How to Use "Something"
“Something” written as one word is an expansion of the pronoun “some.” “Something” is used as a pronoun to take the place of a noun, usually solidifying the relationship of the noun to the rest of the sentence. “Something” as an indefinite pronoun functions uniquely because this term can be modified by adjectives, or descriptive words, following the pronoun, whereas adjectives typically precede nouns and pronouns. For example, “Something sweet was left on the counter.” “Sweet” describes something in this sentence. Other nouns, clauses, verb phrases and prepositional phrases may also modify the pronoun “something.”
How to Use "Some Thing"
“Some thing” written as two words should be viewed as a noun phrase, in which “some” is an indefinite pronoun modifying the noun “thing.” This phrase typically appears in nominal -- or noun-like -- positions, such as the subject, direct object, indirect object and predicate nominative slots. For example, “Some thing is making noise in the closet.” “Some” is modifying the noun “thing,” which is positioned as the subject of the sentence. At times, “some thing” may be written in the plural form by adding an –s to “thing.” For example, “I’m still learning some things about this job.” | <urn:uuid:f0f34647-5042-4cc6-acc9-ec5a1abe369d> | CC-MAIN-2018-26 | https://penandthepad.com/use-thing-vs-something-8737159.html | s3://commoncrawl/crawl-data/CC-MAIN-2018-26/segments/1529267864795.68/warc/CC-MAIN-20180622201448-20180622221448-00537.warc.gz | en | 0.962274 | 380 | 3.8125 | 4 |
Recently I heard that a shortage of shrimp due to disease is causing prices to shoot up. I stopped to wonder how long shrimp had been on American restaurant menus. I could find no instances before the Civil War.
Americans have probably been eating shrimp at home for centuries but shrimp didn’t make a splash in American cookbooks until after the Civil War when they became available in cans. Shrimp salad, usually whole shrimp piled up on lettuce with a mayonnaise dressing, became something of a delicacy that was especially popular with women. It began to show up on hotel menus as well.
Shrimp cocktail, not really so different than shrimp salad, became a staple of banquets in the early 20th century. Instead of mayonnaise a cocktail sauce was used; it was similar or the same as oyster sauce and based on catsup with ingredients such as lemon or vinegar, tabasco or Worcestershire sauce, and horseradish added to give it zing.
Fried shrimp seems to have become a menu item in the early 20th century also, but breaded, deep fried shrimp did not make its big debut until after World War II when pre-cooked frozen shrimp, plain or breaded, came on the market. Then shrimp dinners, relatively cheap because the breading could cover less desirable specimens, became available everywhere, even in many drive-ins.
Until the advent of frozen shrimp, shrimp cocktail and fried shrimp were found most often on menus of restaurants in the Gulf states and California. In the late 19th and early 20th century locally caught shrimp were so plentiful in San Francisco that it was the custom for restaurants to present diners with a free plate of shrimp to nibble on before their meal was delivered.
Importation of shrimp from Mexico and India began in the early 1950s, but evidently it took some time before prices went down. Shrimp cocktail remained a minor luxury for many people through the 1960s. The cost of shrimp was high enough in the mid-1950s to make the theft of frozen shrimp a serious issue for New York’s Mamma Leone’s, which lost thousands of dollars worth of $1.12/lb shrimp to a ring of thieves. The thieves turned out to be a pantry man colluding with garbage collectors who resold the shrimp to other restaurants.
In today’s dollars Mamma Leone’s shrimp cost close to $10/lb, but in actuality prices are much lower than that now due to shrimp farms in Asia and Ecuador that supply most of what Americans eat in restaurants.
One last note, on the distinction among shrimp, scampi, and prawns. This could launch a long discussion about how many species of shrimp there are, what they are called in various parts of the world, etc. But for all practical purposes, in standard menu-ese scampi, often given as “shrimp scampi” on menus, refers to shrimp cooked in butter and garlic and prawns are very large or “jumbo” shrimp. Sometimes the terms are bizarrely combined on menus. The finest example of this I’ve seen was a 1977 Richmond VA menu partially shown above. For an International Seafood Festival it offered an Italian special called Scampi Portofino which was described as “Jumbo Shrimp Prawns.” I guess those were really, really big shrimp-style shrimp.

The assessment showed that 235,000 people are in need of emergency food assistance and an additional 95,000 are in need of complementary food assistance after Tropical Storm Agatha and the eruption of Pacaya Volcano last May.
GUATEMALA– According to an Emergency Food Security Assessment (EFSA) conducted last month, approximately 330,000 people will need food assistance in the coming months to survive.
The assessment --conducted by the World Food Programme, Action Against Hunger, the Mesoamerica Famine Early Warning System (MFEWS), FAO and UNICEF--aimed at determining where, how many and for how long those people affected by Tropical Storm Agatha and the eruption of Pacaya Volcano would need food assistance.
“The situation we are facing is a challenge for the country and the international community. The rainy season is not over yet and the consequences could worsen. This assessment highlights the critical situation and the need for more support”, said WFP Country Director, Willem Van Milink.
The assessment started in August and it showed that 235,000 people are in need of emergency food assistance and an additional 95,000 are in need of complementary food assistance.
Tropical Storm Agatha left behind torrential rains and severe damages all over the country, affecting communications, infrastructure, food security and livelihoods. In addition, Tropical Depression E-11 affected 60 municipalities of 12 departments with a final count of 276 incidents, 225 people dead and millions in damages.
The National Institute of Seismology, Vulcanology, Meteorology and Hydrology (INSIVUMEH) predicted that hurricane season will extend until November. | <urn:uuid:6ffcb461-f335-4b7e-b535-8be4b21cec7b> | CC-MAIN-2014-15 | http://www.wfp.org/node/3475/4320/28369 | s3://commoncrawl/crawl-data/CC-MAIN-2014-15/segments/1398223207046.13/warc/CC-MAIN-20140423032007-00289-ip-10-147-4-33.ec2.internal.warc.gz | en | 0.927854 | 338 | 2.640625 | 3 |
“Never forget.” These are the words that we see broadcast across television advertisements, billboards, and news programs across the American landscape whenever we approach today’s date, September 11. What exactly is it that they never want us to forget? That we responded to a violent act with greater violence and it made the world less safe for everyone? That we allowed ourselves to be misled into a hopeless state of war that few among us truly understood? Or do they mean, “never forget” as in “never forgive”? My sense is probably that it has to do with the latter; an invitation to a perpetual state of violence and insecurity. But then I hear Gandhiji whisper the same words, “Never forget.” What is he doing here, saying the same thing, you wonder?
Here’s a fun and extremely useful nonviolence fact: September 11 is the birthday of Satyagraha, soul-force, clinging to Truth, love in action, the method that Gandhi developed and made into a science over a long career spanning decades of direct practice and experimentation. It was September 11, 1906 and Gandhi and his colleagues had called a meeting to discuss resistance to the Indian Registration Act in South Africa, about which Gandhi said, “shocked him” and “expressed nothing in it but a hatred of Indians.” The ultimate aim of the act was to force Indians to either live as servants in South Africa or to return to India, and it was being watched as an example for other districts as to how they could “successfully” marginalize and discriminate against Indians. Something had to be done to strike such an example at its root, Gandhi was convinced.
At this historic meeting, Gandhi’s colleague Seth Haji Habib suggested that all of those present take a vow to resist the act with extreme dedication. Gandhi watched with interest as the entire room, packed to the brim, seemed to support this idea. But, he thought, if this resistance is really going to make an impact, this vow must be taken in all seriousness, in all consciousness of what it would entail. A vow, he told them, is not something that one simply gives up if it seems inconvenient, one takes on suffering for the sake of a vow, on principle.
While Sir Richard Attenborough’s 1982 film Gandhi dramatized this meeting and Gandhi’s momentous speech to the crowd on the meaning of their oath, here are his actual words, recalled by the Mahatma himself in his book, Satyagraha in South Africa. He describes in detail the consequences of taking the vow of nonviolence over violence, even if one is in a position to use violence:
“We might have to go to jail, where we might be insulted. We might have to go hungry and suffer extreme heat or cold. Hard labour might be imposed upon us. We might be flogged by rude warders. We might be fined heavily and our property might be attached and held up to auction if there are only a few resisters left. Opulent today we might be reduced to abject poverty tomorrow. We might be deported. Suffering from starvation and similar hardships in jail, some of us might fall ill and even die. In short, therefore, it is not at all impossible that we might have to endure every hardship that we can manage, and wisdom lies in pledging ourselves on the understanding that we shall have to suffer all that and worse. (…) But I can boldly declare, and with certainty, that so long as there is even a handful of men true to their pledge, there can only be one end to the struggle, and that is victory.”
With these words, nonviolent struggle took on a new life, a new force that would impact the world forever. He had issued a call to express and endure a love so great that it could end the threat of violence and terror. How about not forgetting that!? And if our media won’t do it, let us do the broadcasting ourselves: we have a choice to go beyond violence for good.

A highly sensitive radio telescope finds a signal source that emits radio waves for weeks and then disappears again within a very short time. Common explanations are excluded.
A previously undiscovered source of the radio signal not far from the galactic center baffles a team of astronomers led by Ziteng Wang of the University of Sydney, Australia. This phenomenon, christened ASKAP J173608.2-321635, cannot be assigned to any previously known cosmic body. Study director Wang believes it is possible to discover a new class of objects that can only be seen at all through radioimaging surveys.
ASKAP J173608.2-32163 was detected using the Australian Square Pathfinder (ASKAP) matrix. It is one of the most sensitive radio telescopes ever. The latest mystery that the telescope has brought to science is not the first, nor is it the only one of its kind that has not yet been resolved, nor is the phenomenon of strange radio circuits still waiting to be solved.
In the case of ASKAP J173608.2-32163, the researchers do not consider it improbable that the signal source eventually was a known type of cosmic object. But at least the definition of such an object should be expanded, according to astronomers in the journal Science Astrophysical Journal. Anyway, Wang could clearly say, “We’ve never seen anything like this.”
Deciphering the phenomenon has become more difficult due to the fact that it cannot be found constantly. Between April 2019 and August 2020, the signal appeared 13 times in the ASKAP data. Follow-up observations in April and July 2020 using the Moriang Radio Telescope in Parks, Australia showed nothing. In contrast, the Meerkat radio telescope in South Africa received success in February 2021. The Australia Telescope Integrated Array (ATCA) detected something in April 2021.
Previously, neither the meerkat nor the ATCA found any data on this signal. The researchers also examined the X-ray and near-infrared observations as well as archives with radio data collected by several instruments. Without success – this signal did not appear anywhere.
Polarization refers to scattering and magnetization. This may be at least in part due to dust and magnetic fields in the interstellar medium between Earth and the source. However, it also appears that it is possible that the source itself is strongly magnetized.
Ultimately, astronomers can’t tell what they’re dealing with. But what they can say is what they don’t deal with. They were able to rule out X-ray binary stars, gamma-ray bursts and supernovae.
Other than that, there are several types of stars that are known to change radio wavelengths. These include stars that flash frequently, or nearby binary stars with an active chromosphere, and stars that obscure each other. However, all of these types should be visible in the X-ray and near-infrared regions, because glowing stars usually have an X-ray emission corresponding to radio emission, and the vast majority of stars have a near-infrared emission ratio that should be discoverable. According to the researchers, a pulsar might also be an option, but that also seems unlikely. Because pulsars send out radio beams at regular intervals. This is exactly what ASKAP J173608.2-32163 doesn’t do – at least not consistently.
Australian astronomers are just as ignorant. Because they were able to prove that the radio object has some characteristics in common with another type of mysterious signal that was discovered in developing countries known as the Central Galactic Transit Radio (GCRT). The catch: its origin is still unclear.
Astronomers now hope to discover another GCRT, ASKAP J173608.2-32163, which may make it easier to find similar sources. The researchers now want to increase the “screening rate”, that is, to search for such phenomena on a larger scale and in a more targeted manner. Only in this way will it be possible one day to name the nature of these observations.

Jews as Nazi Scapegoats
During the 1800s, Germany was pulled into the modern world with the Industrial Revolution. The economy dropped and had many looking for reasons. In the midst of obtaining a German identity, many Germans looked for those that were not entirely “German” as the force behind all of Germany’s problems. One enemy had to be named. The Jew became the obvious scapegoat. Aiding this stance for Germany was Darwin’s published theories of biological evolution. The superior being is the one left standing. Darwin’s works gave the German people a chance to see current history through “a new and meaningful interpretation.” Germany was going to be one of them still standing as their latest military actions showed them to be of the strongest. Biological evolution had to be within the blood.
Despite coming into Germany and becoming “German”, many Jews still followed their religious and ethical traditions. They were German with a Hebrew twist. To many, including the Nazi party, this proved that they were not German and could not be fully assimilated. Only one man was needed to bring the Jewish-German relationship into the racial category. Wilhelm Marr gave the Nazis that weapon.
Unfortunately, most people have to blame someone for their problems. Marr blamed the Jew for his job loss and problems in life. He did not blame an industry, political movement, or even one individual. He blamed an entire group. The need to separate groups and label people was already there. Marr gave it a push in the “right” direction. The “traditional anti-Jewish attitude based on religious and economic stereotypes” was always there and just needed flaming. As more and more intermarriages occurred, the racist used it to prove how the Jew was trying to weaken German blood and destroy the superior race.
The racial categorization by Germans was not held by all Germans. During the boycotts held by the SA, many Germans were not turned away by the SA men standing guard. Public support for the boycotts was minimal. Most Germans continued about their days and even shopped at stores owned by Jews and boycotted by SA men. The Nazis were determined to prove that being German or Jewish was based upon something concrete within the blood. Research was conducted to find that proof and show the world how the Jew could stand out even from a biological perspective. The Nazis searched in vain.
The Nazi party, particularly Hitler, needed someone to focus the country’s attention on and to create a common enemy. If there was an enemy that all Germans could unite against, Hitler had more of a chance to strengthen his power and take Germany in the direction he saw that it needed to go. The common enemy became the Jews. They were different. They were not German. They would be the reason Germany would not survive or become the superior nation that all hoped for. The fact that they seemed to succeed under the Weimer Republic was a good reason to promote their intrigue and evil works. As Hitler painted the Weimer Republic as the reason Germany was held back, it was only logical to show the Jew as part of that dam. Seeing Jews succeeding in strong areas such as the media and entertainment was too much for many who desired power and a strong German presence.
The idea of race became important for the Nazis because they needed to be something that others could not become even if they wanted to. By making everything a racial issue, others could be easily excluded. Being German, according to the Nazi party, was based on what flowed through a person’s veins and not by assimilation into the culture. Blood could not be changed. Therefore, the blood had to be pure. The end result was focusing on the race of each individual. There was no excuse to avoid the purification of Germany.

The Hard Thing About Simple Words
January 23, 2020 • 6 min read
Today, there are a lot of big words used to explain things that could be understood by a larger group of people if instead simpler words were used.
When I write I often fall into this situation myself. It’s easier to use a single big hairy word rather than several smaller, but easier to understand words. These and the following words try to explain something using only the ten hundred most often used words.
Every day, hundreds of hundreds of people visit pages on computers all around the world. These people want these pages to work quickly. This usually means saving as few things as possible when they visit a page. However, if you are the person that writes the directions that computers use to make these pages, that’s probably not how you want to write those directions.
When writing and working on those computer directions, you probably would rather have many small groupings of directions. This way it’s easier to keep everything in your head when working on it. If every single direction was in one grouping, it would be very hard to keep it all in your head. If other people are also making changes at the same time it can be hard to put those together if it’s all in one spot. By having many different direction groupings, it easier to keep all the things you’re working on in your head and another person is probably not also making changes in the same spot.
For a computer place with many pages, it might be written with hundreds and hundreds of groups of direction. But if a person on the other side of the world wants to visit this page, it would take a long time to save all of these different groupings.
The people who write these direction want to work with many small groupings, but the people that view these pages want to save only a few large groupings. So how do we get from hundreds and hundreds of direction groupings into only one big grouping of directions?
The thing that puts different groupings of directions into a single grouping of directions. For short, we’ll call it the Direction Grouper.
How does it work?
To start, the thing itself needs a place to start. That’s the starting point.
It’s possible to have more than one starting point but that’s usually not needed. The Direction Grouper begins at the starting point and finds all of the other direction groupings that the starting point needs. Then it finds the direction groupings that those direction groups need and so on and so on.
As the Direction Grouper jumps around it can then build a huge map of which direction groupings need which direction groupings. This can be any number of layers deep and by the finish point, it may have found hundreds of hundreds of direction groupings.
Once the Direction Grouper finishes building a huge map of all the direction groupings it can then use the map to put all the different groupings into a single big grouping.
When it’s done figuring this out, it then saves this finishing point and this is what people all around the world will then save on their computer when they visit.
To quickly go over, it starts with one direction grouping, finds all the other direction groupings, figures out how to put those all together, and ends with a single huge grouping.
However, it’s doing a lot of other things between the starting point and finish point.
As the Direction Grouper jumps around between direction groupings, it might find different kinds of direction groupings. There can be any number of different kinds of direction groupings, but there are a few that show up often:
- Directions that run on the person’s computer.
- Directions that make things look pretty.
- Directions that show pictures.
- Directions that change the way the words appear when reading.
These are only a few, but there are many more kinds. How is the Direction Grouper supposed to understand so many different things?
The short answer: it doesn’t! Instead, it uses Direction Understanders.
Each different kind of direction grouping has a special Direction Understander that knows how to understand only that kind of direction grouping. When using the Direction Grouper, you can add as many Direction Understanders as you want!
If you need to make things look pretty, then a Pretty Direction Understander is added. If you need to show pictures, then a Picture Direction Understander is added.
Once the directions are understood, you sometimes want to change, add or remove directions.
Direction Changers can be used to change one direction for another, remove extra directions and make them smaller, move directions to another spot, or any number of other things.
There are different work sizes you can use to control how much work the Direction Grouper, Understander, and Changers do.
Changing the directions a lot usually takes a lot more time to run, but it usually means fewer directions for the person on the other side of the world to save so it’s faster for them. Changing the directions less means it runs faster but takes longer for the person to save.
This means when you’re working on the direction and making a lot of changes, you want to make fewer changes to the directions. It will run faster for you to make a lot of changes quickly.
Then, when you are ready to share it with the world, you make a lot of direction changes. You only have to do this once in a while and means the hundreds and hundreds of people that need to save the direction grouping will be able to do so quickly.
There are many single words that could have been used to remove whole parts of this. The next time you’re trying to explain something, consider if you may be ignoring a whole group of people that may be interested in what you’re writing about by using a “big” word where a few of the most used words might do as well. It doesn’t need to be taken this far but it can make you stop and think if you really understand the thing instead of repeating words.
Do you have other ideas for things that you would like to see explained?

Recipient Surgery - Kidney Transplantation
If you have advanced and permanent kidney failure, kidney transplantation may be the treatment option that allows you to live much like you lived before your kidneys failed. Since the 1950s, when the first kidney transplants were performed, much has been learned about preventing rejection and minimizing the side effects of medicines.
But transplantation is not a cure; it’s an ongoing treatment that requires you to take medicines for the rest of your life. A successful transplant takes a coordinated effort from your whole health care team, including your nephrologist, transplant surgeon, transplant coordinator, pharmacist, dietitian, and social worker. But the most important members of your health care team are you and your family. By learning about your treatment, you can work with your health care team to give yourself the best possible results, and you can lead a full, active life.
When Your Kidneys Fail
Healthy kidneys clean your blood by removing excess fluid, minerals, and wastes. They also make hormones that keep your bones strong and your blood healthy. When your kidneys fail, harmful wastes build up in your body, your blood pressure may rise, and your body may retain excess fluid and not make enough red blood cells. When this happens, you need treatment to replace the work of your failed kidneys.
How Transplantation Works
Kidney transplantation is a procedure that places a healthy kidney from another person into your body. This one new kidney takes over the work of your two failed kidneys.
A surgeon places the new kidney inside your lower abdomen and connects the artery and vein of the new kidney to your artery and vein. Your blood flows through the new kidney, making urine like your kidneys did when they were healthy. Unless they are causing infection or high blood pressure, your kidneys are left in place.
The Transplant Process
YOUR DOCTOR’S RECOMMENDATION
The transplantation process begins when you learn that your kidneys are failing, and you must start to consider your treatment options. Whether transplantation is among your options will depend on your specific situation. Transplantation isn’t for everyone. Your doctor may tell you that you have a condition that would make transplantation dangerous or unlikely to succeed.
MEDICAL EVALUATION AT A TRANSPLANT CENTER
If your doctor sees transplantation as an option, the next step is a thorough medical evaluation at a transplant hospital. The pretransplant evaluation may require several visits over several weeks or even months. You’ll need to have blood drawn and x rays taken, and you’ll be tested for blood type and other matching factors that determine whether your body will accept an available kidney.
The medical team will want to see whether you’re healthy enough for surgery. Cancer, a serious infection, or significant cardiovascular disease would make transplantation unlikely to succeed. In addition, the medical team will want to make sure that you can understand and follow the schedule for taking medicines.
HOW IS A KIDNEY TRANSPLANT PROCEDURE PERFORMED?
There are two major sources of potential kidney donors:
- Living related donors: Close relatives of the patient. E.g., parents, siblings, children, and grandparents are the most potential donors. A normal individual has two kidneys, and a person can easily live in good health with one kidney without any complications. Kidney donation does not harm the physical strength or the donor’s lifestyle.
- Cadaver donors: A cadaver kidney is available from the individual declared as brain-dead. For example, for a person who expired due to an accident or stroke, the reason must be non-kidney related. In several cases, the cadaver kidney may not be a feasible candidate for the transplantation, as, firstly, all the pre-screening criteria should match the patient. In an unsuccessful match, the patient would have to wait further.
Suitability is initially based on two factors:
- Blood type. Your blood type (A, B, AB, or O) must be compatible with the donor’s blood type.
- HLA factors. HLA stands for human leukocyte antigen, a genetic marker located on the surface of your white blood cells. You inherit a set of three antigens from your mother and three from your father. A higher number of matching antigens increases the chance that your kidney will last long.
If you’re selected based on the first two factors, a third is evaluated:
- Antibodies. Your immune system may produce antibodies that act specifically against something in the donor’s tissues. A small sample of your blood will be mixed with a small sample of the donor’s blood in a tube to see whether this is the case. If no reaction occurs, you should be able to accept the kidney. Your transplant team might use a negative cross-match to describe this lack of reaction.
If you have a living donor, you’ll schedule the operation in advance. You and your donor will be operated on simultaneously, usually in side-by-side rooms. One team of surgeons will perform the nephrectomy-that is, the removal of the kidney from the donor-while another prepares the recipient for placement of the donated kidney.
If you’re on a waiting list for a deceased donor kidney, you must be ready to hurry to the hospital as soon as a kidney becomes available. Once there, you’ll give a blood sample for the antibody cross-match test. If you have a negative cross-match, your antibodies don’t react, and the transplantation can proceed.
You’ll be given a general anesthetic to make you sleep during the operation, which usually takes 3 or 4 hours. The surgeon will make a small cut in your lower abdomen. The artery and vein from the new kidney will be attached to your artery and vein. The ureter from the new kidney will be connected to your bladder.
Often, the new kidney will start making urine as soon as your blood starts flowing through it, but sometimes a few weeks pass before it starts working.
RECOVERY FROM SURGERY
After any major surgery, you’ll probably feel sore and groggy when you wake up. However, many transplant recipients report feeling much better immediately after surgery. Even if you wake up feeling great, you’ll need to stay in the hospital for about a week to recover from surgery and longer if you have any complications.
Your body’s immune system is designed to keep you healthy by sensing “foreign invaders,” such as bacteria, and rejecting them. But your immune system will also sense that your new kidney is foreign. To keep your body from rejecting it, you’ll have to take drugs that turn off or suppress your immune response. You may have to take two or more of these immunosuppressant medicines and medications to treat other health problems. Your health care team will help you learn what each pill is for and when to take it. Be sure that you understand the instructions for taking your medicines before leaving the hospital.
If you’ve been on hemodialysis, you’ll find that your post-transplant diet is much less restrictive. You can drink more fluids and eat many fruits and vegetables you were previously told to avoid. You may even need to gain a little weight, but be careful not to gain weight too quickly and avoid salty foods that can lead to high blood pressure.
You can help prevent rejection by taking your medicines and following your diet, but watching for signs of rejection-like fever or soreness in the area of the new kidney or a change in the amount of urine you make, is important. Report any such changes to your health care team.
Even if you do everything you’re supposed to do, your body may still reject the new kidney, and you may need to go back on dialysis. Unless your health care team determines that you’re no longer a good candidate for transplantation, you can go back on the waiting list for another kidney.
SIDE EFFECTS OF IMMUNOSUPPRESSANTS
Immunosuppressants can weaken your immune system, which can lead to infections. Some drugs may also change your appearance. Your face may get fuller; you may gain weight or develop acne or facial hair. Not all patients have these problems, though, and diet and makeup can help.
Immunosuppressants work by diminishing the ability of immune cells to function. In some patients, this diminished immunity can increase the risk of developing cancer over long periods. Some immunosuppressants cause cataracts, diabetes, extra stomach acid, high blood pressure, and bone disease. These drugs may also cause liver or kidney damage in a few patients when used over time.
Treatment for kidney failure is expensive, and post-surgery, also you need to spend a good amount of money on your routine prescribed drugs.
Post Transplant Care:
Once the transplantation is performed, the patient needs to stay in the hospital for a regular diagnosis with regular follow-ups by the doctor. One would even need to get his blood regularly tested at least for 1-2 months. The average recovery period is about six months. The patient needs to get regular blood tests and x-rays done for the next few years, even after the recovery. | <urn:uuid:40ab5b12-c740-499e-bec1-8daa431d2725> | CC-MAIN-2023-50 | https://urocarechennai.com/treatments/recipient-surgery/ | s3://commoncrawl/crawl-data/CC-MAIN-2023-50/segments/1700679100518.73/warc/CC-MAIN-20231203225036-20231204015036-00163.warc.gz | en | 0.945843 | 1,957 | 3.015625 | 3 |
Parental Involvement vs. Parental Interference
College of Liberal Arts, English Major, Class of 2013
At some point during your student’s college career, your son or daughter will undoubtedly call you with a problem or concern. A parent’s role is to be there, listen, and decide whether to become involved or let students solve the problem on their own.
Whenever your student has questions about University policies, procedures, or resources, first give your student the responsibility to resolve the issue. When students take care of their own problems, they develop important problem-solving skills and gain confidence in themselves. If your student feels overwhelmed by a situation, you can provide guidance by determining the category that best fits the concern—then let your student take control.
For academic issues, students can talk to the instructor if the concern is related to a specific class; otherwise they can talk to their academic adviser. Academic advisers provide guidance on working effectively with instructors, planning an academic schedule, and finding tutoring. Students will find the name of their adviser on the student web portal.
If there are issues in the residence hall, students should first talk to their community adviser (CA), but if additional assistance is required, they may contact their hall director. For commuter issues, the Commuter Connection office provides guidance and direction on issues related to the commuter experience.
Though students should attempt to solve their problems on their own, there are certain situations in which parents should be involved. These situations include when a student is too ill to handle the situation, the student has mental health issues that prevent him or her from making informed decisions, a student’s finances are likely to affect family finances, or the parents cannot locate the student. These situations require advice or action as a parent. Before you become involved with your student’s issue, however, remember that growth and maturity comes from dealing with decisions, and a big part of college is making choices—even wrong ones—as well as from taking responsibility for both the good and the bad consequences of their decisions. | <urn:uuid:6744cf57-117b-4879-9e6a-db382e861891> | CC-MAIN-2015-14 | http://www1.umn.edu/parent/news-events/articles/fall-2012/parental-involvement-vs-parental-interference/index.html | s3://commoncrawl/crawl-data/CC-MAIN-2015-14/segments/1427131298464.94/warc/CC-MAIN-20150323172138-00249-ip-10-168-14-71.ec2.internal.warc.gz | en | 0.964546 | 420 | 2.703125 | 3 |
A national recycling competition by TerraCycle is encouraging students to go head-to-head as they collect oral care waste, diverting traditionally non-recyclable items from landfill and giving them a new lease of life.
A new online Learning Centre launched by Junior Landcare features curriculum-aligned activities that aim to encourage young students to be aware, empowered and active in caring for their local environment.
An urban farm incorporated into a Victorian primary school is on the way to producing over 1.5 tonnes of fresh produce a year, providing its students with access to a wide range of fruit and vegetables, and assisting in teaching the importance of growing food and healthy eating.
A new Australian recycling program by TerraCycle is encouraging schools, offices and communities to collect used pens, markers and other writing instruments; diverting them from landfill and transforming them into something entirely new.
FEAST, a new curriculum aligned education program from OzHarvest that inspires kids to eat healthy food, waste less and become change-makers in their local communities will be rolled out across Australia.
According to Senior Business Development Manager at Flow Power, Tricia Lorenzo, it’s crucial for schools to take a forward-thinking approach when it comes to sustainability. She discusses some tips on creating future-proofed school sustainability strategies.

Iberian lynx are generally nocturnal creatures, with peak activity occurring at twilight when individuals leave shelter in order to forage (5). Both sexes are solitary and territorial, with male territories overlapping those of several females (5). Females reach sexual maturity at one year of age but will only breed once they are in possession of their own territory (6). The mating season peaks at the beginning of the year in January and February and births occur two months later (5). The female cares for her litter of one to four kittens (5) within a lair that may be located under a thicket or in a hollow tree. Weaning occurs at around eight months but juveniles tend to stay in their natal territory until they are around 20 months old (6). European rabbits (Oryctolagus cuniculus) make up the mainstay of the diet of the Iberian lynx, unlike the larger Eurasian lynx that feeds mainly on ungulates such as roe deer (Capreolus capreolus) and chamois (Rupicapra rupicapra) (4). Small deer may be eaten on occasion, if rabbit numbers are low (6).

Electric Vehicles(EV) runs with the help of an electric motor and is taken as an environment-friendly alternative to the conventional internal combustion engine where the mix of gases and fuel is burnt to generate power.
Electric cars use what is called a ‘Large Traction Battery Pack’ for the electric motor to run and it needs to be charged by plugging into a charging station. As the technology gets more sophisticated the electric vehicles are getting smarter and effective with each day passing.
Like almost anything in the world, Electric cars comes with several pros and cons.
Table of Contents
Pros of Electric Cars
If you think about electric vehicles without any prejudice, its full of goodness and efficiency. I mean there is no negative impact of using an electric vehicle. 2018 was when the record number of electric vehicles were sold and the number always seems to grow.
Electric cars do not burn fuel or emit harmful gases. They do not produce sound like the fuel machines. With zero emissions, you’ll be doing your bit to save the environment from global warming and other environmental hazards.
Since the electric vehicles do not require any mechanical engine to operate, there is relatively lesser wear and tear in the body parts of the vehicles.
3. Ideal for Urban Driving
Urban cities are full of stoppages and frequent traffic congestion takes a toll while driving through cities. The fuel consumption cost is reduced and the same distance of urban commute can be accomplished at a much lesser cost.
If you’ve driven a fuel engine before, you’ll realize the costs associated with the maintenance of the engine and their parts, all those costs are eliminated with the electric motors.
5. Driving Dynamics
People experienced with the conventional fuel engine vehicles will immediately realize how easy and comfortable it is to dive an electric vehicle.
The instant torque helps the vehicle to shift gears easily and it has a smoother pickup and acceleration. Electric vehicles are designed in such a way its easier to handle as far as the center of gravity and the chassis volume is concerned.
The one-pedal driving helps decelerate faster and the brake pedal is hardly used.
6. Extra Storage
The electric cars are designed with much less volumetric mass and the space that conventional cars would occupy is used for storage of luggage and stuff.
Cons of Electric Cars
1. Requires charging stations
It’s self-explanatory that electric vehicles need to be charged once the battery power drains out. So the charging stations need to be installed in several locations as the gas stations for conventional vehicles.
2. Range Issue
The total distance an electric car covers once fully charged is very hard to know. The manufacturers claim is hard to achieve in the real world. The weather in the real world plays a vital role in draining out the battery power which is probably the number never match.
Since the production is still quite low, the price charged for an electric vehicle is often premium. However, the governments approach to waving tax for electric vehicles has been a lifesaver for those who are interested in electric cars.

When rescue teams arrived on the scene, they had to break out two windows in her still-running truck to get to Debra Hyde and her eight-month-old grandson. Hyde’s truck was still in “Drive” in front of a large wall of propane tanks, when rescue workers found her overdosed on heroin in the backseat of her truck.
This is at least the second time in the past month that Ohio authorities have found a grandparent or guardian overdose in a vehicle with a child. Earlier in the month, Ronda Pasek and her boyfriend were found overdosed with a child in the backseat, and she is now sentenced to a 180-day sentence for a misdemeanor charge of “child endangerment.” In both cases, the children involved were remanded to the care of child services.
1,424 people died in Ohio, in 2015, as a result of drug overdoses. This has forced first responders to reconsider not only how they prepare for their jobs – Naloxone kits are essentially a “must,” these days – but, how they respond to the burgeoning epidemic that plagues their state. In Marion, OH, and across the nation, heroin has fundamentally altered the work of police and emergency-service workers. Police and paramedics are now expected to play the roles of social workers, drug-treatment specialists, and experts at connecting with kids in drug-prevention programs (as those of us who remember D.A.R.E. can attest).
Marion Police Chief, Bill Collins, told his officers to stop charging those who overdosed, while at the same time, he was making connections with religious leaders, healthcare professionals, addition treatment providers, and teachers to find ways to help better address drug addiction within his community. He followed the evidence: many addiction surveys indicate that a large number of opioid addicts became addicted to prescription pain killers after gaining access to their parents’, grandparents’, or guardians’ properly (or improperly) prescribed opioid painkillers and began using them recreationally. In addition, he noticed that many of the people who were being found overdosed had kids in local schools, which further indicated that a great place to start would be within the educational paradigm.
With these things in mind, Collins and his allies helped create the “Too Good for Drugs” campaign, that teaches age-specific strategies that students can use to resist drugs. The program won a $25,000 Ohio Department of Education grant to fund the ten-week program for 6th-12th grade students. Teachers were so passionate about the project that they volunteer to teach it. Officials are still waiting to find out if another grand to extend the program to K-5th grade students is approved.
But, beyond the fact that these functions are becoming unlisted job requirements in these fields, should law enforcement officers and other first responders be expected to fill these roles? What few people contest is that “something” needs to be done; beyond that, there’s little agreement between healthcare professionals, law enforcement organizations, and advocacy groups on exactly what that “something” is.
Do we need more treatment centers for drug addiction, both in- and out-patient? Absolutely. Do we need more qualified social workers and staffing resources to adequately address opioid and other drug addiction? Yep. Do we need to do a better job of providing these recovery and addiction services to people in more rural parts of states – areas where opioid and heroin addiction are currently hitting states hardest? There’s no doubt of that.
But, the reality is that all of these approaches, while both the “right things to do” and the best ways we currently have to address the problem, are costly and require resources that, on the state and local levels, may simply not exist. Further complicating these efforts is the seeming inability of our elected leaders at the Federal level to work together toward accomplishing mutually beneficial goals. For states currently watching their cities turn into drug dens with a body count, it really does seem like the time for them to just get it together, and get to work.

The following two US Army intelligence reports provide a fascinating insight into the initial Allied reaction to the first appearances of the Tiger tank on the battlefields of North Africa.
US Army Intelligence Report Technical and Tactical Trends, February 1943
This is a heavy tank. No details other than the actual nomenclature are known, but it seems probable that this model is an entirely new departure in German tank design. It has been anticipated for some time that the Marks IIl and IV might be superseded by a new type incorporating the best features of each model and introducing features borrowed from British and possibly American designs. Having obtained a tank gun of first quality in the long-barrelled 75-mm tank gun (40), the weapon mounted in the new Mark IV tanks, it is probable that this weapon or an 88-mm weapon is the principal armament. The basic armor may be as thick as 80 or 100 mm, and spaced armor, at least in front, is probably incorporated. There may also be skirting armor. Face-hardened armor is probably used, and the speed is not expected to be under 25 mph.
Reports of a German heavy tank have been received over a considerable period of time. Apparently the most recent is the statement of a German captured in Tunisia. According to the prisoner, he belonged to an independent heavy tank battalion, which consisted of a headquarters company and two armored companies. Each armored company was equipped with nine 50-ton tanks. The tanks were armed with 88-mm guns and were capable of a speed of 50 kilometers (about 30 miles) an hour. Whether or not this is the Mark VI tank is not known.
US Army Intelligence Bulletin, June 1943
In Tunisia the German Army sent into combat, apparently for the first time, its new heavy tank, the Pz. Kw. 6, which it calls the “Tiger”. The new tank’s most notable features are its 88-mm gun, 4-inch frontal armor, great weight, and lack of spaced armor. Although the Pz. Kw. 6 has probably been adopted as a standard German tank, future modifications may be expected.
The “Tiger” tank, which is larger and more powerful than the Pz. Kw. 4,1 is about 20 feet long, 12 feet wide, and 9% feet high. The barrel of the 88-mm gun overhangs the nose by almost 7 feet. The tank weighs 56 tons in action (or, with certain alterations, as much as 62 tons), and is reported to have a maximum speed of about 20 miles per hour. It normally has a crew of five.
The armament of the Pz. Kw. 6 consists of the 88-mm tank gun (Kw. K. 36), which fires fixed ammunition similar to, or identical with, ammunition for the usual 88-mm antiaircraft-antitank gun; a 7.92-mm machine gun (MG 34) which is mounted coaxially on the left side of the 88-mm; and a second 7.92- mm machine gun (MG 34) which is hull-mounted and fires forward. In addition, a set of three smoke-generator dischargers is carried on each side of the turret.
The turret rotates through 360 degrees, and the mounting for the gun and coaxial machine gun appears to be of the customary German type.
The suspension system is unusually interesting,. The track is made of metal. There are no return rollers, since the track rides on top of the Christie-type wheels, which are rubber rimmed. It will be noted that there are eight axles, each with three wheels to a side, or each with one single and one double wheel to a side. There are thus 24 wheels—8 single wheels and 8 double wheels on each side of the tank. The system of overlapping is similar to the suspension system used on German half-tracks.
The armor plating of the Pz. Kw. 6 has the following thicknesses and angles:
Lower nose plate: 62 mm (2.4 in), 60° inwards.
Upper nose plate: 102 mm (4 in), 20° inwards.
Front plate: 62 mm (2.4 in), 80° outwards.
Driver plate: 102 mm (4 in), 10° outwards.
Turret front, and mantlet: Possibly as much as 200mm (8in), rounded.
Turret sides and rear: 82 mm (3.2 in), vertical.
Lower sides (behind bogies): 62 mm (2.4 in), vertical.
Upper sides: 82 mm (3.2 in), vertical.
Rear: 82 mm (3.2 in), 20° inwards.
Floor: 26 mm (1 in).
Top: 26 mm (1 in).
The angular (as opposed to rounded) arrangement of most of the armor is a bad design feature; reliance seems to be placed on the quality and thickness of the armor, with no effort having been made to present difficult angles of impact. In addition, none of the armor is face-hardened. The familiar German practice of increasing a tank’s frontal armor at the expense of the side armor is also apparent in the case of the Pz. Kw. 6.
Undoubtedly the Germans developed the “Tiger” tank to meet the need for a fully armored vehicle equipped with a heavy weapon capable of dealing with a variety of targets, including hostile tanks. Although the “Tiger” can perform these duties, its weight and size make it a logistical headache. It is entirely probable that the Germans, realizing this disadvantage, are continuing to develop tanks in the 30-ton class. Further, it is interesting to note that the Pz. Kw. 6 has proved vulnerable to the British 6-pounder (57-mm) antitank gun when fired at a range of about 500 yards. | <urn:uuid:6bc9f902-1865-439a-b2f2-f4271bf0951d> | CC-MAIN-2020-16 | https://germanwarmachine.com/despatches/wehrmacht-in-action/tiger-encounter | s3://commoncrawl/crawl-data/CC-MAIN-2020-16/segments/1585370504930.16/warc/CC-MAIN-20200331212647-20200401002647-00262.warc.gz | en | 0.959014 | 1,229 | 2.84375 | 3 |
Macroeconomics models are ways of predicting the behavior of the economy. Two models dominate modern thinking: the classical model and the Keynesian model.
The classical model was popular before the Great Depression, a time of serious economic downturn in the 1930s. In this model, the economy is self-adjusting: in good times, wages and prices rise, while in bad times, wages and prices fall. Prior to the Great Depression, this model seemed to hold true, because small fluctuations occurred in the business cycle, an interval of expansion and contraction in the economy. The business cycle is normal for a healthy economy and tends to follow the economy's overall economic growth.
The Great Depression, however, represented a major failure of the classical model. The economy did not self-adjust, and the effects were severe and widespread. In response, the Keynesian model was developed, which posits that the economy does not self-adjust. The Keynesian model relies on governments to implement fiscal policies in order to stabilize economic fluctuations.
The classical economic theory, based on the ideas of Adam Smith, focuses on a long-run approach to achieving economic growth. Adam smith was a Scottish philosopher and economist who lived in the 18th century. The classical theory holds the economy will fluctuate around full-employment gross domestic product (GDP) and a rate of natural unemployment. Gross domestic product (GDP) is a measurement of a country's total economic output. Two assertions are made by the classical theory. First, the main focus is on economic growth or producing more output, which is determined at the full-employment level of GDP. Second, advocates of the classical theory assert that wages and prices are flexible and will adjust back to full-employment GDP in the long run. Therefore, intervention by the government to assist in economic downturns is not supported by the classical theory. In addition, the government should focus less on short-term fluctuations in GDP or on the business cycle and focus more on growing full-employment GDP, because the economy rebounds and returns back to full-employment GDP. If this is the case, then policy should focus on long-term growth in national productivity, which will lead to an increase in full-employment GDP. To help foster growth in national productivity, tax rates should be kept low, and an emphasis should be put on allowing businesses to make optimal investment decisions by increasing competition and removing monopolies. The classical theory strongly favors supply-side policies that help to increase and shift the long-run aggregate supply curve, thus increasing real GDP and keeping price levels low. Other policies the classical theory supports to achieve long-run economic growth are savings and investment, education, technology, and research and development. This model essentially translates to letting markets take the lead, and having an emphasis on long-run aggregate supply.
A tangential point to this idea is Say's law, which is the theory that supply creates its own demand. According to Say's law, when an individual produces a product or service, they get paid for that work, and are then able to use that income to demand other goods and services. The classical theory also views the Phillips curve as vertical, which implies that there is no negative relationship between unemployment and inflation in the long run. The argument is that the natural rate of unemployment is also vertical, and fluctuations in unemployment vary around this natural rate. Per the classical theory, an economy without the assistance from government adjusts back to its long-run potential output. The policy implication is that the government should instead keep inflation rates low.
While in the long run there is an upward trend toward the full-employment level of of GDP, the reality is that certain phases of the business cycles (recessions, troughs, contractionary phases) have a negative impact on lives. Unemployment affects families—the Great Depression is an example of the despair that can be caused by downturns. The return to full-employment GDP may take a long period of time. The Keynesian theory, initially proposed by John Maynard Keynes, a British economist in the 19th and early 20th centuries, argues that something should be done to smooth out business cycles (maintain a constant and positive GDP growth rate) to keep employment levels consistent and close to a rate of full employment and to keep inflation at a low, consistent rate.
Keynesian models focus on short-run fluctuations in the business cycle instead of solely focusing on long-term growth. The Keynesian view argues two points. First, aggregate demand (the overall demand for goods and services) is a key aspect with respect to production, because it provides incentives to hire labor and bring production closer to full-employment GDP. Second, in the short run, wages and prices are sticky (or rigid) as opposed to flexible. If prices and wages are sticky, they do not respond to increases or decreases in aggregate demand, and an excess of supply is created. The evidence for these proposals came directly from analyzing the Great Depression. During this era, production capacity did not change and there were no major supply shocks, yet there was a large-scale contraction in the economy. This would be a contradiction to Say's law, which would suggest that supply should have created the demand. It did not. Under the Keynesian view, the government should implement an expansionary fiscal policy (increase spending and reduce taxes) in cases of recessionary gaps and should implement a contractionary fiscal policy (reduce spending and increase taxes) in times of inflationary gaps. These policies focus on shifting aggregate demand to hopefully smooth out short-run fluctuations in business cycles. | <urn:uuid:ddfaea3b-0bd0-4e7a-b5f3-c532b2ffb65a> | CC-MAIN-2023-23 | https://www.coursehero.com/sg/macroeconomics/macroeconomic-viewpoints/ | s3://commoncrawl/crawl-data/CC-MAIN-2023-23/segments/1685224657169.98/warc/CC-MAIN-20230610095459-20230610125459-00057.warc.gz | en | 0.95264 | 1,144 | 4.25 | 4 |
In Canada, geoscience is a regulated profession. To practice, a geoscientist must register as a P.Geo. and get a licence from the regulatory body – professional association – in each province or territory in which they practice. Geoscientists Canada is the national organization of 9 regulatory bodies that govern Canada’s more than 9,500 Professional Geoscientists (P.Geo.’s) and more than 2,000 Geoscientists-in-training.

"Providing the public with information about Earth and its mysteries is the way I share my passion for geology."- John Clague, P.Geo.
Every day, we use information geoscientists provide and don’t even realise it. When we use our mobile devices, ride a bicycle, get a glass of water, drive across a bridge or through a tunnel, turn on a light or look into a mirror, a geoscientist had something to do with it.

Careers in Geoscience
"P.Geo. is a badge I wear proudly. Our regulatory system in Canada is one of the most respected in the world, so having a P.Geo. designation speaks volumes about what I bring to the table."- James Moors, P. Geo.
BECOMING A P.GEO.
Geoscientists are professionals like architects, doctors, lawyers, foresters and engineers. You wouldn’t hire an unlicensed lawyer or accountant to be your advisor or allow an unlicensed surgeon to operate on you, so why would you hire an unlicensed geoscientist to work for you? Part of the drive to regulate the profession of geoscience came in the wake of the Bre-X gold mining fraud and the Walkerton groundwater contamination incident; two examples where better public governance of geoscientific practice in Canada could have provided greater protection of the public and prevented loss of reputation about the work of geoscientists.

PRACTICE IN CANADA
Being a P.Geo. places you under a code of ethics and makes you individually accountable for all the geoscience work you undertake. To practice geoscience in Canada, you must register with the regulatory body – professional association – in the province or territory in which you work. Those whose practice extends to more than one province or territory may have to carry multiple registrations. Becoming registered entitles you to practice in that jurisdiction and it allows you to use the designation Professional Geoscientist (P.Geo.).

Researchers say lab-based tests may be boon to both clinicians and researchers
In the current online issue of PLoS ONE, researchers at the University of California, San Diego School of Medicine say they have identified a set of laboratory-based biomarkers that can be useful for understanding brain-based abnormalities in schizophrenia. The measurements, known as endophenotypes, could ultimately be a boon to clinicians who sometimes struggle to recognize and treat the complex and confounding mental disorder.
“A major problem in psychiatry is that there are currently no laboratory tests that aid in diagnosis, guide treatment decisions or help predict treatment response or outcomes,” said Gregory A. Light, PhD, associate professor of psychiatry and the study’s first author. “Diagnoses are currently based on a clinician's ability to make inferences about patients' inner experiences.”
Diagnosing and treating schizophrenia is a particularly troubling challenge. The disorder, which affects about 1 percent of the U.S. population or roughly 3 million people, is characterized by a breakdown of normal thought processes and erratic, sometimes dangerous or harmful, behaviors.
“Schizophrenia is among the most severe and disabling conditions across all categories of medicine,” said Light, who also directs the Mental Illness, Research, Education and Clinical Center at the San Diego VA Healthcare System.
The precise cause or causes of schizophrenia are not known, though there is a clear genetic component, with the disorder more common in some families.
Clinicians typically diagnose schizophrenia based upon inferences drawn from the patient’s inner experiences. That is, their ability to describe what’s happening inside their minds.
“But even the best clinicians struggle with diagnostic complexities based on sometimes fuzzy clinical phenomenology,” said Light. The clinical challenge is compounded by the fact that “many schizophrenia patients have cognitive and functional impairments,” said Light. They may not be able to reasonably explain how or what they think.
Light and colleagues investigated whether a select battery of neurophysiological and neurocognitive biomarkers could provide clinicians with reliable, accurate, long-term indicators of brain dysfunction, even when overt symptoms of the disorder were not apparent. These markers ranged from tests of attention and memory to physiological assessments of basic perceptual processes using scalp sensors to measure brain responses to simple sounds.
The researchers measured the biomarkers in 550 schizophrenia patients, and then re-tested 200 of the patients one year later. They found that most of the markers were significantly abnormal in schizophrenia patients, were relatively stable between the assessments and were not affected by modest fluctuations in clinical status of the patient.
Light said further research is required, including whether the endophenotypes can differentiate other psychiatric disorders, be used to anticipate patient response to different kinds of drugs or non-pharmacological interventions or even be used to predict which subjects are at high risk of developing a psychotic illness.
“We believe this paper is an important step towards validating laboratory-based biomarkers for use in future genomic and clinical treatment studies of schizophrenia,” Light said.

Intel® Learn Program
Empowering youth around the world
The Intel® Learn Program is an informal and engaging educational program designed to develop the technology skills of young learners in developing countries. The program uses creative, technology-based projects to tap into children’s interest in their own communities, and helps them build the skills they need to create solutions.
Intel Learn is comprised of three units:
- Technology and Community
- Technology at Work
- Technology and Entrepreneurship
A trained community center staff member guides young learners through activities in a series of two-hour sessions. Each session is divided into action-oriented sections: “Plan It,” “Do It,” “Review It,” and “Share It,” each of which helps develop technical and critical-thinking skills.
Students then work together to collect information, analyze it, and present it to fellow learners, families, and community leaders.
Technology and Community
The Technology and Community curriculum uses activities and projects to show students how they can use technology to contribute to their communities. This curriculum teaches the following skills:
- Word processing
- Internet search
Technology at Work
Technology at Work demonstrates how computers are used in a variety of jobs and careers. As students work on their projects, their use of application software and the Internet becomes increasingly sophisticated. Projects range from healthcare survey designs to the kind of project management plan that a local engineer might create.
Technology and Entrepreneurship
Technology and Entrepreneurship introduces the basic concepts of entrepreneurship and shows how technology can be used to advance a business idea.

The famous Welch paper says Forty-eight of the 50 state health departments in the United States responded to a questionnaire about giardiasis in their jurisdictions. The agencies had reports of 34348 cases during 1991 and studied 80 outbreaks in the same period. Nineteen of these outbreaks were attributed to consumption of contaminated drinking water; only two outbreaks were reported among individuals identified as campers or backpackers. http://www.ncbi.nlm.nih.gov/pubmed/11995903
Following is my attempt to look at these numbers in a different, and what I think is a more telling, way.
The CDC estimates there are an upwards of 2.5 million cases of giardiasis annually in the U.S. http://www.giardiasis.org/
Using the 2-7% infection rate for developed countries would actually mean there are a minimum of 6,680,000 cases a year. But we'll take the lowest number of 2,500,000 cases, of which 34,348 were reported in 1991. 2,500,000 - 34,348 = 2,465,652 unreported cases. That means about 98.6% of cases go unreported. That figure supports what many physicians say, they usually don't report Giardia.
A disease outbreak is defined as "the occurrence of cases of disease in excess of what would normally be expected in a defined community, geographical area or season." Thus, in 1991 there were only 80 outbreaks reported, or at least studied, out of 34,348 reported cases.
Now by my reasoning there would be a lot more reported outbreaks around large numbers of people sharing the same food and water (swimming pools, day care centers, rest homes etc,) if so the ratio of outbreaks/vs individual cases would skew towards the under reporting of individual backpacker Giardia, regardless of source. But we'll go with the low numbers again. Out of 80 actual outbreaks total, 2 were reported from contaminated drinking water from campers and backpackers. That's 2.5%.
If 2.5% of national Giardia cases are caused by camper/backpacker drinking water (2.5% times 2.5 million) that's 62,500 cases a year, minimum, of campers/backpackers contracting Giardia from contaminated water, extrapolating from the official numbers.
Now I grant there are some fuzzy numbers in there, but I think they are a lot more representative of the truth than this quote, based on the same fuzzy base numbers and used over and over again in literature attempting to promote the "myth" of getting giardia from backcountry drinking water: Nineteen of these outbreaks were attributed to consumption of contaminated drinking water; only two outbreaks were reported among individuals identified as campers or backpackers. That number of 62,500+ sounds a lot different than 2.
Check my numbers. If I've made any errors point them out and I'll make the changes. | <urn:uuid:dca02812-7aa8-42c8-a6c0-d0480f0e09f0> | CC-MAIN-2015-18 | http://www.backpackinglight.com/cgi-bin/backpackinglight/forums/thread_display.html?forum_thread_id=43422&skip_to_post=370610 | s3://commoncrawl/crawl-data/CC-MAIN-2015-18/segments/1429246633512.41/warc/CC-MAIN-20150417045713-00304-ip-10-235-10-82.ec2.internal.warc.gz | en | 0.968994 | 614 | 3.234375 | 3 |

The Cognitive Benefits of Interactive Video
Learning and Instruction
Media, such as photos, audio explanations and video, is becoming increasingly common and valuable as a learning resource. In The Cognitive Benefits of Interactive Videos: Learning to Tie Nautical Knots, Stephan Schwann and Roland Riempp reveal that media is more than just a mediated presentation of information:
Iconic media, however, should not be thought of as merely a convenient means of storing and transmitting visual information that is otherwise more or less cognitively equivalent to its " natural " unmediated counterparts. Instead, it should also be realized that one of the main benefits of media-based information presentations is that contents can be customized according to the cognitive needs of users (294).
Media producers can focus on certain components to help the viewer understand the material in a way that would be more efficient than watching an entire process from start to finish from an unmediated perspective. For example, a producer can zoom on a certain part, can spend more time explaining a more complicated component of the process, and can make it easier for the viewer to process the information by cutting out any distractions.
Schwann and Riempp explain that interactive media is a step above non-interactive media for learning because non-interactive media is generally designed for the masses. While non-interactive media will have cognitive benefits for learners, interactive media provides even greater cognitive benefits because learners can control the information they receive. " Interactive media enable the user to adapt the presentation to her or his individual cognitive needs by actively deciding about the " what" and the " how" of a given presentation(296). "
They prove that interactive media improves the learning process for procedural tasks through an experiment in teaching nautical knots. Students were either shown the full length instruction or provided the ability to control what portion of the video was watched at a certain time. Students with access to the interactive versions took a little more than half as much time to learn the material as students who could not control the viewing experience. This improved learning time was attributed to the students ability to distribute their cognitive resources to the sections they needed to focus on more.
Businesses can certainly leverage the benefits of using interactive video for training materials as well. By simply adding chapter markers and menus to make it easier for learners to get to a section, or through immediate probing and follow-up questions to ensure the learners gleaned the important information from the media and keep viewers engaged, the interactivity may help reduce the amount of time it takes learners to learn how to use a software, apply a product, and follow a process.

The spring melt is on, and every hike lately means wet feet. We live along the Wisconsin River, so I’ve been thinking about where all that spring runoff goes. In Wisconsin, we have what are called “Best Management Practices for Water Quality”. These are voluntary practices for forestry that help us protect our riparian areas, or the interface between our land and water. The intent of these recommendations is to prevent polluted runoff (soil, chemicals, and nutrients) from getting in to lakes and streams, and also to prevent temperatures from rising too much in the water. Those of you that like to fish and boat in this state will especially appreciate these efforts. That said, there are some recommended practices that can help you in your own woodland management, such as securing your roads and trails for the long-term.
As I mentioned earlier, these practices are considered voluntary. They are suggested guidelines for a variety of forestry work. However, if you work with a DNR forester or a Cooperating forester, they are required to follow these practices. There are some other times these may be required as well, such as if you are in the American Tree Farm system. The BMPs apply when you are working within 35 feet of a small stream or 100 feet of a lake or river. If you are doing road/trail work, water crossings, timber sales, tree planting, or prescribed burns, there is a best management practice for you.
Most of the practices around roads/trails are generally intended for temporary logging roads or permanent forest roads. However, if you do trail work on your property, I would recommend taking a look at some of the recommended practices. There are some nice design elements that can make your trails last longer and be more resilient to long-term use with less maintenance. For example, they walk you through whether you will want your trail vegetated or graveled depending on type of use and traffic. You’ll also find ways to deal with drainage from your trail so you aren’t battling wash-outs or pooling water.
There are two things to consider when you undertake a planting project in a riparian area: exposing bare soil and use of chemicals. Preparation for planting and planting itself is usually most effective when space is cleared for young trees to flourish. This can be a problem if your site is susceptible to runoff. The recommendations here include waiting to plant until conditions are drier and running any equipment on the contour. In addition to protecting water quality, you are also protecting your investment in those trees from washing away during a heavy rain event. If you are using chemicals (herbicides or fertilizers), the number one recommendation is to follow the directions on rates. Take it a step further by using only chemicals that are labeled for use near lakes and streams.
If you are working with a contractor, forester, logger or other resource professional, you have a water body on your property, and you want to protect your woods, check out the other chapters in the Best Management Practices field guide. We have the field guide along with several other Forestry Facts for BMPs on our website: https://woodlandinfo.org/woodlandinfo/publications/forest-management#bmps One more thing, you can use these recommendations around vernal pools too (which will be popping up soon), and you can learn more about why vernal pools are so cool, in a previous blog post: Vernal Pools are Springing Up | <urn:uuid:4e15771e-b63c-4a8d-b375-7e70063e8167> | CC-MAIN-2023-06 | https://woodlandinfo.org/something-in-the-water/ | s3://commoncrawl/crawl-data/CC-MAIN-2023-06/segments/1674764500058.1/warc/CC-MAIN-20230203154140-20230203184140-00422.warc.gz | en | 0.957799 | 716 | 2.734375 | 3 |
Most of my students have trouble with the idea that a book — especially a textbook — can lie. That’s why I start my U.S. history class by stealing a student’s purse.
As the year opens, my students may not know when the Civil War was fought or what James Madison or Frederick Douglass did; but they know that a brave fellow named Christopher Columbus discovered America. Indeed, this bit of historical lore may be the only knowledge class members share in common.
What students don’t know is that their textbooks have, by omission or otherwise, lied to them.
This lesson was published by Rethinking Schools in Rethinking Columbus. For more lessons like “Discovering Columbus: Re-reading the Past,” order Rethinking Columbus with more than 80 essays, poems, interviews, historical vignettes, and lesson plans. See Table of Contents.
The Discovering Columbus lesson helps students contextualize perspective and point of view in a very real fashion, and provided an invaluable jumping off point for assessing perspective, context, and validity in history. —Jessica Pullen, middle school social studies teacher, Anacortes, WA
I teach 5th graders and we have been learning about mesoamerican cultures. We have been shifting into how these cultures were impacted and destroyed by European explorers. Comparing and contrasting history texts that are told from different perspectives has really helped my students to see both sides of the story and see the injustices that have occurred throughout history. I wish their were more resources available to teacher that help shed light on the non-white perspective of history. My fifth graders are fired up and engaged about their learning now! —Shannon Jaeger, elementary school teacher, Richfield, MN | <urn:uuid:9f05e001-12a2-4d76-87d5-e70e3b51b093> | CC-MAIN-2023-23 | https://www.zinnedproject.org/materials/discovering-columbus/ | s3://commoncrawl/crawl-data/CC-MAIN-2023-23/segments/1685224644683.18/warc/CC-MAIN-20230529042138-20230529072138-00731.warc.gz | en | 0.954989 | 363 | 3.609375 | 4 |

If you knew about breakthrough advances in science and technology, would you use — demand — them?`
What’s 300x stronger than steel, harder than diamond, conducts electricity and heat better than copper and is only one carbon atom thick?
Graphene — the “wonder material”
Graphene is a two-dimensional (2D) atomic crystal which consists of carbon atoms arranged in a hexagonal lattice. It’s been studied as far back as 1859. But the breakthrough discovery which catapulted graphene into a technological building-block-wonder is good old Scotch tape.
In 2004, Professor Andre Geim and Professor Kostya Novoselov, at The University of Manchester, discovered a simple way to produce large samples of graphene. They were awarded the Nobel Prize in Physics in 2010 for their discovery, which they called the “Scotch tape method”, also known as the micromechanical cleavage technique.
Ten years later, European nation’s “regional” approach to basic research graphene has created a bazillion applications in industries as diverse as: aerospace, automotive, electronics, energy storage, coatings and paints, communications, sensors, solar, oil and pharmaceuticals. Go here for more. And, here, too.
I’m excited about graphene’s use in solar because it has the potential to greatly increase solar cell efficiency as well as accelerate cost reduction.
A. “Despite its many desirable qualities and potential applications, graphene still isn't as widely used as it could be for one main reason – it's difficult to apply to surfaces, particularly large ones. Attempting to do so often causes damage to the graphene, or otherwise results in a non-uniform, flawed coating. Now, however, scientists have devised a method of simply spraying the stuff on, that actually improves the graphene in the process.” See: “Scientists create 'spray-on graphene'”, Ben Coxworth, 29 May 2014, Gizmag.
B. “For all the attention graphene gets thanks to its impressive list of properties, how many of us have actually encountered it in anything other than its raw graphite form? Show of hands. No-one? That's because it is still difficult to mass-produce without introducing defects. Now a team at the Korea Institute of Science and Technology (KIST) has developed a graphene substitute from plastic that offers the benefits of graphene for use in solar cells and semiconductor chips, but is easy to mass-produce.” See: “Polymer-based graphene substitute is easy to mass-produce”, Darren Quick, 4 July 2014, Science Daily. Source: KIST.
C.“A graphene coating has been used to boost thermal conductivity of the common plastic polyethylene terephthalate (PET) by up to 600 times. This new result from an international team of physicists and engineers could substantially increase the use of PET and other plastics in technologies such as solid-state lighting and electronic chips, where the ability to conduct heat is essential.” See: “Graphene boosts thermal conductivity of popular plastic”, 28 Oct 2014, at physicsworld.com.
D. “An international team of researchers has developed a drug delivery technique that utilizes graphene strips as 'flying carpets' to deliver two anticancer drugs sequentially to cancer cells, with each drug targeting the distinct part of the cell where it will be most effective. The technique was found to perform better than either drug in isolation when tested in a mouse model targeting a human lung cancer tumor.” See: “'Flying carpet' technique uses graphene to deliver one-two punch of anticancer drugs”, Matt Shipman, Phys.org, 6 Jan 2015.
E. “Graphene just might be the world's most incredible material. A honeycomb-like sheet of pure carbon only one atom thick, it's one million times thinner than a human hair and yet 200 times stronger than steel. It's also an excellent conductor of heat and electricity and is stretchable, flexible, transparent, and impermeable.”
“And now scientists at Caltech in Pasadena, Calif. say they have figured out how to make the stuff on an industrial scale--a breakthrough that could open the floodgates to a seemingly endless array of graphene-based products.” See: “Graphene Is The World's Most Amazing Material, And Now We Have A Simple Way To Make It”, David Freeman, 19 Mar 2015, The Huffington Post.
A. “Apply a layer of zwitterionic fullerenes...”
“For decades, polymer scientists and synthetic chemists working to improve the power conversion efficiency of organic solar cells were hampered by the inherent drawbacks of commonly used metal electrodes, including their instability and susceptibility to oxidation. Now for the first time, researchers at the University of Massachusetts Amherst have developed a more efficient, easily processable and lightweight solar cell that can use virtually any metal for the electrode, effectively breaking the "electrode barrier.” 'This barrier has been a big problem for a long time,' says UMass Amherst's Thomas Russell, professor of polymer science and engineering. 'The sun produces 7,000 times more energy per day than we can use, but we can't harness it well. One reason is the trade-off between oxidative stability and the work function of the metal cathode.' Work function relates to the level of difficulty electrons face as they transfer from the solar cell's photoactive layer to the electrode delivering power to a device.” See: “A more efficient, lightweight and low-cost organic solar cell”, University of Massachusetts Amherst, 18 Sept 2014, Phys.org.
B. “A multidisciplinary engineering team at the University of California, San Diego developed a new nanoparticle-based material for concentrating solar power plants designed to absorb and convert to heat more than 90 percent of the sunlight it captures. The new material can also withstand temperatures greater than 700 degrees Celsius and survive many years outdoors in spite of exposure to air and humidity. Their work, funded by the U.S. Department of Energy's SunShot program, was published recently in two separate articles in the journal Nano Energy.” See: “New solar power material converts 90 percent of captured light into heat”, 29 Oct 2014, University of California, San Diego.
C. “UNSW Australia's solar researchers have converted over 40% of the sunlight hitting a solar system into electricity, the highest efficiency ever reported.” See: “Researchers convert sunlight to electricity with over 40 percent efficiency”, 7 Dec 2014, University of New South Wales, Phys.org. | <urn:uuid:0a1ad124-cb8f-4634-acf1-4d8e6004358c> | CC-MAIN-2021-49 | https://brkthu.org/science_technology.html | s3://commoncrawl/crawl-data/CC-MAIN-2021-49/segments/1637964363510.40/warc/CC-MAIN-20211208114112-20211208144112-00303.warc.gz | en | 0.937967 | 1,420 | 3.71875 | 4 |

Shifting winds have helped drive West Antarctica’s ice sheet melting for millennia, according to a new analysis that could help scientists better anticipate sea-level rise.
The findings, published yesterday in the journal Nature, show that during the past 11,000 years, wind patterns have driven relatively warm waters from the deep ocean onto Antarctica’s continental shelf, leading to significant and sustained ice loss. That influx of warm water then halted for several millennia before beginning again around 1940.
More data are needed to explain those shifts, but atmospheric temperatures likely played a role, said Claus-Dieter Hillenbrand, the study’s lead author and a senior marine geologist with the British Antarctic Survey. Whatever the reason for shifts, the results demonstrate the importance of climate models accounting for the region’s winds.
“By understanding the mechanisms that caused the retreat of the [West Antarctic Ice Sheet] over the past several thousand years, we can begin to build a clearer picture of what is happening today,” Hillenbrand said.
Gerhard Kuhn, co-author of the study, said, “Our results provide evidence that in the past, [West Antarctic Ice Sheet} retreat was also predominantly caused by melting through warm ocean water.”
Kuhn, from Germany’s Alfred Wegener Institute, added, “This gives confidence in the predictions of the current generation of ice sheet models which are used to forecast future ice loss from Antarctica and resulting sea-level rise.”
The area studied two of the continent’s largest glaciers, Thwaites and Pine Island, which drain into the sea and contribute to rising sea levels. But scientists have struggled to pinpoint how much—and how quickly—that should affect climate change models, with researchers in the last two years suggesting a U.N. panel had underestimated its impact by half, according toThe New York Times.
The new research draws from sediment samples taken at Pine Island Bay—one of the continent’s most inhospitable areas and, consequently, one of its least understood. The first reliable measurements of the area weren’t taken until 1994, so it’s hard to come by data that are more than a few decades old, said Hillenbrand.
The international research team spent 10 years collecting and analyzing sediment samples in order to find microfossils. Analyzing the chemical composition of those shells “acts like a fingerprinting” for the water’s temperature, Hillenbrand said, enabling researchers to trace the intervals when relatively warm water welled up onto the continental shelf.
The scientists say more research is needed to fine-tune their understanding. For instance, these findings trace the relative difference in water temperature, but more study is needed to ascertain the absolute temperatures from those periods.
“It’s often a hit-or-miss” in that area around the Amundsen Sea, Hillenbrand said, adding that researchers were able to flag areas for sampling but occasionally had to depart. “The conditions were changing, the wind picked up and got stronger, so it was impossible to hold the ship on station, or an iceberg came along so that the ship had to move out of the way.”

Ivory Coast. At the end of May, Mali's Minister of
Justice announced that about 10,000 children from his home
country had been sold as slaves in neighboring Ivory Coast.
Countryaah, these were children aged 8–16 who were sold to coffee and
cocoa growers in Ivory Coast by their parents in the
drought-affected Mali. The countries signed an agreement to
fight illegal child trafficking.
In connection with the Ivory Coast celebrating its 38th
anniversary as an independent nation in August, President
Henri Konan Bédié issued an amnesty covering 3,600 of the
country's prisoners. The exceptions were those convicted of
violent crimes, drug offenses or misappropriation of public
funds. Amnesty, however, provided that the prisoner could
set up a bail sum or repay any theft.
UN diplomat Aliounie Blondin Beyes was killed when his
aircraft crashed on June 26 shortly before landing in the
Ivory Coast administrative seat Abidjan. Beyes was on his
way to the Ivory Coast during a tour he undertook among
African states to gain a hearing for his Angola peace plan. | <urn:uuid:9ecab4e5-5fb6-4778-abe3-12aa2198d93a> | CC-MAIN-2020-29 | https://constructmaterials.com/Ivory_Coast.html | s3://commoncrawl/crawl-data/CC-MAIN-2020-29/segments/1593655882634.5/warc/CC-MAIN-20200703153451-20200703183451-00064.warc.gz | en | 0.976827 | 241 | 2.8125 | 3 |
SAN FRANCISCO, Aug. 5 (UPI) -- U.S. researchers say a 10-year census of marine life has identified areas of the world's oceans with the highest species diversity -- and areas most at risk.
Scientists participating in the international Census of Marine Life have tallied an average of 10,000 known marine species in each of 25 important ocean zones, and discovered 1,200 new species, ScienceNews.org reported this week.
Researchers say Australian and Japanese ocean waters, each with about 33,000 species, top the list for highest diversity among the 25 regions surveyed, and the Gulf of Mexico, surveyed before the oil spill, ranked in the top five with 15,374 species.
The seas around China and the Mediterranean Sea were also high in biodiversity.
The census identified the biggest threats to sea life, with overfishing being the most serious, followed by habitat destruction from coastal development, pollution, trawling and other human activities.
The census gives "the first integrated look at the diversity and distribution of life in the oceans," marine ecologist Daria Siciliano of Sea Web in San Francisco said.
"In the wake of an oil spill in U.S. waters that is likely the worst environmental disaster in history, I hope the public is more likely to pay attention to what happens to the oceans," Siciliano said. | <urn:uuid:ad1d1e98-587e-406e-ab2a-9b454cc1654e> | CC-MAIN-2015-40 | http://www.upi.com/Science_News/2010/08/05/Historic-census-of-sea-life-completed/UPI-61401281043802/ | s3://commoncrawl/crawl-data/CC-MAIN-2015-40/segments/1443736680773.55/warc/CC-MAIN-20151001215800-00143-ip-10-137-6-227.ec2.internal.warc.gz | en | 0.940823 | 281 | 3.21875 | 3 |
Higher level math is a big part of any PhD program in economics -- to the extent that students with bachelors degrees in mathematics are more likely than students with bachelors degrees in economics to be admitted into economics PhD programs, according to the California State University website. Not all math is equally relevant to studying economics at the PhD level, though. The most important kinds of math for someone pursuing a PhD in economics are linear algebra, multivariable calculus, probability theory and real analysis.
Someone pursuing a PhD in economics should study linear algebra. Linear algebra uses linear equations in the study of multidimensional matrices. In economics, being able to create and manipulate matrices provides a means of analyzing how economic factors interact. For example, linear algebra techniques can be used to study how changing domestic production rates effect foreign trade, says Steve Levandusky of Bucknell University in Pennsylvania.
Multivariable calculus is also important to study early in preparation for an economics PhD. Multivariable calculus allows for non-linear rates of change and multiple variables, which, for economists, allows for very detailed analysis of how economic factors interact. According to professors from the School of International and Public Affairs at Columbia University, economists can use multivariable calculus to evaluate things like the factors consumers consider before making purchases, the tradeoffs between labor and capital and the potential value of increasing or decreasing the production rate of a product.
One of the more specialized kinds of math economists use is probability theory. Where algebra and calculus allow for the creation and analysis of known sets of data, probability theory allows analysis of the unknown. It considers known data along with elements of chance to predict outcomes. Economists might use this to help a company decide how much or whether to place a bid for a government contract, for example.
R analysis is often cited as the most important math course for economics PhD preparation, according the California State University website. The "real" refers to the discipline's focus on real numbers, which excludes imaginary numbers and infinity. Real analysis builds on calculus and provides a foundation for the kinds of applied mathematics that are useful in economic study. Real analysis is especially valued by economics PhD programs because of its emphasis on writing and understanding proofs. | <urn:uuid:03b0e434-cff5-4412-acf3-f1bc01b9663c> | CC-MAIN-2018-47 | https://www.theclassroom.com/important-math-phd-economics-6005.html | s3://commoncrawl/crawl-data/CC-MAIN-2018-47/segments/1542039743011.30/warc/CC-MAIN-20181116111645-20181116133645-00227.warc.gz | en | 0.914274 | 448 | 2.671875 | 3 |
Endangered Species Act Endangered?
August 15, 2008Rapid City, SD - Conservation groups say the Endangered Species Act will be endangered itself if a new set of rules proposed by the Bush administration goes into effect. Jim Margadant, regional conservation coordinator for the South Dakota Sierra Club, says the plan lets each federal agency decide if its own actions or projects might harm a species.
He warns they eliminate the requirement that federal agency plans be approved by the U.S. Fish and Wildlife Service or the National Marine Fisheries Service. The new rules, which came from Department of Interior Secretary Dirk Kempthorne, caught everyone by surprise, Margadant says.
"Kempthorne states flat out that this relates back to the polar bears' listing due to the effect of greenhouse gases and climate change. In his press releases, he's very up-front about that. He does not want to see the Endangered Species Act being used as a way to regulate greenhouse emissions or to address the effects of climate change."
The administration defends the rules change, saying it allows agencies to approve new pesticides and projects to reduce wildfire risks. But Margadant worries the action will allow every federal agency to do what it wants, free of oversight from scientists and wildlife professionals. He is especially concerned because it was an executive decision, which is not subject to Congressional review.
"That makes this an end run around the legislation. Congress would have to act specifically to stop this. They could change the law, but that's a rather harsh measure. Essentially what's going to happen is it's going to end up in the courts and litigation, and then we'll hear a bunch of people screaming about judges making law."
A 30-day public comment period on the rules begins when the proposed revisions appear in the Federal Register. | <urn:uuid:ccb52809-cee7-4c47-afe6-844cda53261d> | CC-MAIN-2019-35 | http://4x4wire.com/categories/accesslanduse?start=100 | s3://commoncrawl/crawl-data/CC-MAIN-2019-35/segments/1566027315809.69/warc/CC-MAIN-20190821043107-20190821065107-00068.warc.gz | en | 0.952689 | 369 | 2.875 | 3 |
NHS England has refused funding for a breakthrough drug that can help children with a life threatening disease live long and healthy lives. The drug, everolimus, treats tuberous sclerosis complex, or TSC, which can cause non-cancerous tumors to grow and cause seizures and infections. Life expectancy can be as little as 12 months, but everolimus has been demonstrated to shrink these tumors and stabilize patients. The drug is expensive, but treating the damage caused by TSC is even more expensive. NHS England will reevaluate funding for everolimus in 2017.

Slavery in America for Kids - Who was Harriet Tubman?
Harriet Tubman was an escaped slave herself. She was helped to freedom by the Underground Railroad. By then, it was no longer necessary to reach Canada. If a slave could reach Philadelphia, they would be free. After working for about a year in Philadelphia, saving money, Harriet Tubman managed to return to her former home in Maryland, where she had been a slave. She went there to help her husband escape and to bring him back with her to Philadelphia. But her husband had married someone else in her absence and did not wish to leave. She returned to Philadelphia, and decided to devote her life to helping other slaves escape.
She served as a conductor on the Underground Railroad for the next 10 years. Her route was moving fugitive slaves from Wilmington, Delaware to Philadelphia. It was the most dangerous route as it was the last leg on the Underground Railroad. By the time runaways reached Harriet, they were exhausted. They were easy prey for slave catchers. Harriet gave them hope. She shoved and pushed and carried them to freedom. Since slavers were out and about, seeking fugitive slaves between Wilmington and Philadelphia, Harriet knew she had to keep her runaways hidden from sight and sound. She carried opium with her to give to babies to keep them quiet. She carried a pistol and was not afraid to use it. Harriet Tubman helped more than 300 slaves to freedom along the Underground Railroad. Thanks to the abolitionist press, and their frequent stories about Harriet Tubman and the dangers she faced to help the plight of slaves, many people knew her name. By 1860, the South had put a bounty on her head of $40,000! Many slave catchers tried to earn that bounty, but no one ever caught her!
Harriet Tubman did more than lend her support to the Underground Railroad. In 1862, during the Civil War, she traveled to an island off the shore of South Carolina. The island and its residents were under the protection, by then, of the U.S. Army. The residents were slaves abandoned by their owner. They spoke their own language. They knew nothing about life on the mainland or in the rest of the country. They were very alarmed at all the Union soldiers who had descended on their island. Harriet had her hands full trying to gain their trust.
The first thing she did was build a wash house. She set up a business with the island women washing Army uniforms. She was paid by soldiers in both cash and goods. The island woman had no use for the cash, but they loved the goods. Harriet split up their earnings equally, taking only her share. She took her share in cash. She also went along with the Army on raids to the mainland, seeking slaves to rescue. One time, traveling with a gunboat, she brought back over 700 slaves and left several mainland plantations on fire. She was an amazing woman. No Union soldier ever tried to turn her in for the bounty, in part because Confederate money could not be used in the North and was losing value rapidly even in the South. But having someone wash their clothes until they were truly clean, free of lice and filth, that was worth buying!
By 1864, the year before the Civil War ended, Harriet Tubman decided to retire. She had saved enough money on the island, washing soldiers clothes, to pay for her needs for many years to come. She returned to her home in Auburn, New York. She lived there for the rest of her life. | <urn:uuid:091a087a-5753-4bb9-a894-04d0d10a10bf> | CC-MAIN-2023-40 | https://civilwar.mrdonn.org/harriet-tubman.html | s3://commoncrawl/crawl-data/CC-MAIN-2023-40/segments/1695233511000.99/warc/CC-MAIN-20231002132844-20231002162844-00470.warc.gz | en | 0.99307 | 723 | 4.15625 | 4 |
Tanzania’s growth is natural resources-intense. The country uses biomass to satisfy most of the population’s energy needs; around 30% of its gross domestic product (GDP) is provided for by agriculture and fishing; and wildlife-based tourism generates over 13% of the country’s GDP. Water resources, land, forests, are all critical to Tanzania’s economy, and they are under threat due to competing demands, over-exploitation, and climate change, amongst others. Climate change is one of the largest threats to development, and an issue that could push millions into poverty if action is not taken. Tanzania has a – rapidly shrinking – opportunity to harness its natural capital in a sustainable way. The good news is, multiple examples exist in-country and elsewhere on sustainable approaches to natural resources management. | <urn:uuid:4a184a7a-916a-4d3a-86a2-6de36c60a19f> | CC-MAIN-2020-50 | https://www.worldbank.org/en/news/video/2019/05/09/tanzania-and-the-important-role-of-its-rich-natural-resources | s3://commoncrawl/crawl-data/CC-MAIN-2020-50/segments/1606141176049.8/warc/CC-MAIN-20201124082900-20201124112900-00647.warc.gz | en | 0.925429 | 172 | 3.203125 | 3 |

Physical Education is “education through the physical”. It aims to develop students’ physical competence and knowledge of movement and safety, and their ability to use these to perform in a wide range of activities associated with the development of an active and healthy lifestyle. It also develops students’ confidence and generic skills, especially those of collaboration, communication, creativity, critical thinking and aesthetic appreciation. These, together with the nurturing of positive values and attitudes in PE, provide a good foundation for students’ lifelong and life-wide learning.

Last year as part of our Visible learning project, we spent a lot of time discussing with children, staff and parents the qualities that make a good learner. After making children aware of their learning process and planning dedicated lessons on being a good learner, we asked children in our parliament assemblies to define the key elements of what makes a good learner at our school. The views of the children across the school were compiled and we created a shared vocabulary of twelve features (shown below). These consist of things we use in lessons such as success criteria and the Rubrics grid which explain what needs to be included in a successful piece of work. This language has been shared with all children and used daily to ensure children are thinking about how they are approaching their work and how they could be better learners.
This will be discussed further, alongside some of our other exciting teaching and learning approaches in our parent workshop: Accelerating your child’s progress through Visible learning. This will be on November 23 rd at 9.00 am and 6.30 pm.
What constitutes ‘good’ teaching and ‘good’ learning is a complex and controversial issue. Educational agencies in New Zealand, like those in other western countries, have called for synthesis of research evidence (see Anthony & Walshaw, 2007; Stanley, 2008; Ingvarson, Beavis, Bishop, Peck, & Elsworth, 2004; National Mathematics Advisory Panel, 2008; Sullivan, 2011) to inform policy and professional development initiatives aimed at improving the quality of teaching and learning outcomes.

Abstract Knowledge of biomass properties and/or fuel characteristics is the basis for bioenergy or chemical conversion processes. Biomass properties are variable and associated with plant species and assortments, therefore, identifying the associations will be important for understanding mechanisms behind the variations and for improvements in predicting biofuel characteristics and management of sustainable feedstock production. A data synthesis was carried out based on data of energy properties including contents of carbon (C), hydrogen (H), oxygen (O), nitrogen (N), sulfur (S) and ash (A) (CHONSA) in variable biomass species and assortments. Data were collected from 260 peer-reviewed literatures and composed of 742 data objects of more than 144 species. Principal component analysis (PCA) was used to analyze the data. The analyses were carried out at five levels of plant classifications, respectively: levels 1–3 for life-forms, level 4 for assortments and level 5 for species. All the loading plots produced for the energy properties showed the following groupings: C, H and O; ash; N and S. The score plots showed a large natural variation between life-forms for herbaceous materials but more homogeneous for woody ones. Thus, an ordering of energy properties for variable biomass was achieved and correlations between biomass properties and species groups were shown. The general trend was: wood→herbaceous dicots+C4 graminoids→C3 graminoids along the PCA axis from CH rich to ash rich, which is consistent with the empirical knowledge that wood is a high quality but grass a low quality fuel during a combustion. A robust analysis confirmed the findings by PCA. The analyses in this study indicated that the C, H, and O contents are much less variable than those of N, S and total ash. The ash content had the largest role in differentiating biomass energy properties between species and between assortments. | <urn:uuid:a4c31fc6-f5e4-440b-b433-de4f9d6c6d8e> | CC-MAIN-2017-09 | https://www.mysciencework.com/publication/show/c5feb4bf9a658a42accfe2611edec90c | s3://commoncrawl/crawl-data/CC-MAIN-2017-09/segments/1487501174167.41/warc/CC-MAIN-20170219104614-00033-ip-10-171-10-108.ec2.internal.warc.gz | en | 0.945896 | 389 | 2.765625 | 3 |
A Data Scientist is a problem solver who solve complicated problems from business users.
They want to forecast something; they want to understand how data can improve their business. They figure out – how can we utilise that data to actually provide value to the business. They use different tools for different visualizations and then make sense out of that data. Being a data scientist is the challenge. It’s almost like being an investigative journalist, investigating a story; you never know what are you going to find when get your hands on this new set of data.
According to Harvard Business Review, a Data Scientist “is a high-ranking professional with the training and curiosity to make discoveries in the world of Big Data”. With experts predicting that 40 zettabytes of data will be in existence by 2020 , Data Science career opportunities will only shoot through the roof!
Shortage of skilled professionals in a world which is increasingly turning to data for decision making has also led to the huge demand for Data Scientists in start-ups as well as well-established organizations. Presently, there are only 10,000 - 15,000 analytics and data experts in India and there will be a shortage of 2 lakh data scientists in India over the next few years
A Data Scientist dons many hats in his/her workplace. Not only are Data Scientists responsible for business analytics, they are also involved in building data products and software platforms, along with developing visualizations and machine learning algorithms.
The opportunities in Data Science are huge.

Research is being done on the stories of families intimately affected by wars that generate brutality, sadness, and social crises.
These studies analyze the correspondence of the life stories of separated couples, of women enduring violence, absence, and death.
Researchers also address the history of “children of war” born during or shortly after the conflicts. For example, children conceived by love or from the rape of an enemy soldier (and “of women to boches”) or allied (sometimes of color).
There are also the stories of children of prisoners taken to Germany or of workers requisitioned by the Obligatory Work Service.
These “children of war” are victims of family secrets, heavy silences, abandonment, resentment, racist mockery, and sometimes even bullying and murder.
Many have embarked on a quest for identity, a problematic search conducted by discovering “a hidden letter, a forgotten photo, etc.”. They find themselves thanks to various sources, oral and written, more and more often digitized: civil status registers, matriculation registers, military files and death records, reports, and interviews of witnesses. But also thanks to international associations (BOW: an international network of children of war) or appeals launched on social networks.
In addition, multidisciplinary scientific studies (archaeological, anthropological, and genetic identification) have been conducted following the discovery of soldiers’ remains. This has made it possible to unravel the mysteries of the unknowns uncovered, whose history can be traced through associated objects (jacket buttons, identity plates, bracelets, and engraved watches) and through molecular analysis (ancient DNA) of bones, teeth, hair… or even the oral condition. | <urn:uuid:f6b8c2fc-4ded-418e-a99d-15c74b2e2da6> | CC-MAIN-2022-40 | https://www.landofmemory.eu/en/sujets-thematiques/children-of-war/ | s3://commoncrawl/crawl-data/CC-MAIN-2022-40/segments/1664030334644.42/warc/CC-MAIN-20220926020051-20220926050051-00184.warc.gz | en | 0.935745 | 354 | 3.265625 | 3 |

En excerpt from the book :
IN CANCER THERAPY"
by Ross, R.Ph. Pelton, Lee Overholser
AT HOSPITAL SANTA MONICA we have pioneered in the administration of hydrogen peroxide to treat cancer and other conditions. Our doctors have administered over 40,000 infusions of hydrogen peroxide
(H2O2) intravenously and have treated thousands of patients with oral doses. Other clinics offering alternative cancer treatment are now using hydrogen peroxide routinely, and some physicians in the U.S. are experimenting with it.
As far back as the early nineteenth century, hydrogen peroxide was widely used in medicine. Many bacterial diseases, including syphilis, responded to
H2O2 when no other treatment was effective. In the early twentieth century H2O2
was used to treat several common diseases, such as typhoid fever, cholera, ulcers, asthma, whooping cough, and tuberculosis. (11)
Hydrogen peroxide's ability to kill bacteria in the human body has been well documented (1, 13, 17), and a 1922 medical textbook describes the use of hydrogen peroxide orally, by intravenous injection, and for topical use. (14) However, as the pharmaceutical industry began to develop powerful new (and high-priced) drugs, hydrogen peroxide was increasingly ignored and finally discarded as a treatment.
Several fascinating personalities have been involved in the struggle to gain recognition in the U.S. of hydrogen peroxide as a therapeutic agent again. Dr. Edward Rosenow (1875-1966), a physician and research scientist associated with the Mayo Clinic for over forty years, discovered that hydrogen peroxide was the safe, effective antimicrobial, antiviral agent he had spent years looking for. Unfortunately, he died without seeing his discovery become widely accepted.
However, his friend Father Wilhelm, a Catholic priest and chemistry teacher, made a commitment to publicize the wonderful benefits of hydrogen peroxide. In the 1970s he presented Rosenow's research to several large pharmaceutical companies, only to get the same response every time: Rosenow's work on hydrogen peroxide was very interesting and potentially important, but hydrogen peroxide was an inexpensive substance that could not be patented and had no commercial value.
Walter Grotz was the next player in the hydrogen peroxide story. After a 1965 auto accident, Grotz developed arthritis that was so bad he could hardly walk. In the winter of 1982, after retiring as postmaster in Delano, Minnesota, his wife convinced him that a warm Caribbean cruise might lessen his arthritic pain. As fate would have it, the chaplain on their cruise ship was Father Wilhelm. When Father Wilhelm learned that Wally (as he is affectionately called) had arthritis, the good Father began preaching his "peroxide sermon."
Wally began taking small amounts of hydrogen peroxide orally, and within a few months his arthritis pain was totally gone. Walter became as committed as Father Wilhelm, and the two of them have now dedicated their lives to spreading the word about the potential health benefits of hydrogen peroxide.
Hydrogen Peroxide in Nature
When ozone mixes with moisture in the air, it forms hydrogen peroxide, which comes down in rain and snow. It occurs naturally in fresh fruits and vegetables, some coming from rain and some manufactured during photosynthesis. (6) Hydrogen peroxide is also found in mother's milk, with an especially high concentration in colostrum (the first milk secreted, right after birth).
One researcher states, "The generation of
H2O2 in cellular processes seems to be purposeful, and H2O2 cannot be dismissed as a mere undesirable by-product.... The capacity for generation of H202 is now found to be widespread in a variety of organisms and in the organelles of the cells." (12)
The Chemistry of Hydrogen Peroxide
Hydrogen peroxide is a very simple compound, with the chemical I formula
H2O2 Essentially it is a molecule of water with an extra atom of oxygen attached, occurring throughout nature and produced by almost every cell in the human body.
Most people are familiar with the common drugstore variety of 3-percent hydrogen peroxide, used for everything from sterilizing a cut to cleaning kitchen countertops. Hydrogen peroxide's sterilizing power comes from its extra oxygen atom. Hydrogen peroxide has a similar oxidizing, or cleansing, power in the body. However, the drugstore variety of
H2O2 should never be used internally, because of the chemicals it contains as stabilizers.
In the 1950s Dr. Denham Harman developed the free-radical theory of aging. Free radicals are molecules that have a chemically active oxygen atom attached to them. Free radicals can damage cells, causing aging and cancer. (15)
At first it seemed that extra oxygen was always damaging, and that the antioxidants were the good guys, responsible for anti-aging protection. Now it appears that not all free-radical reactions are bad. For instance, oxygen helps cleansing enzymes remove toxins, and it is used by the immune system to attack invading bacteria. (4) Also, hydrogen peroxide stimulates natural killer (NK) cells, which attack cancer cells as these attempt to spread throughout the body. (8)
Oxygen and Cancer
Otto Warburg won the Nobel Prize for his discovery that cancer cells have different metabolic properties than normal cells. (16) Healthy cells are aerobic; they use oxygen in most of their chemical reactions. Cancer cells have reverted to a more primitive metabolic process, called fermentation which is anaerobic, or without oxygen. This means that cancer cells thrive in a low-oxygen environment.
The main energy source for both normal and cancer cells is glucose. However, a cancer cell's anaerobic processing of glucose yields only one fifteenth the energy per glucose molecule, compared with normal cellular metabolism. This is why cancer cells have such a huge appetite for sugar (glucose).
Mechanism of Action
One possible way in which intravenous hydrogen peroxide can treat cancer is by releasing pure oxygen in the body. By saturating the cells and tissues with oxygen, hydrogen peroxide promotes healthy, oxygen-based metabolism.
Dr. Charles Farr discovered that intravenous hydrogen peroxide stimulates oxidative enzymes in the body, which help to clear out toxins. (5) He found that intravenous
H2O2 infusions almost doubled the metabolic rate. These changes may account in
part for the observed benefits from H2O2 infusions.
It is important to note that H2O2 apparently does not produce free-radical lipid peroxidation, but instead stimulates important detoxifying oxidative enzyme systems. This is the direct opposite of what might be expected.
Many people, including myself, initially reacted negatively to the idea of taking hydrogen peroxide internally. How could something that produces free radicals possibly have a therapeutic benefit? However, the damage from free radicals comes from chronic exposure to free-radical oxygen, which is part of more complex molecules. The processes of oxygenation and stimulation of the oxidative enzymes may account for the positive effects of hydrogen peroxide that have been observed.
In the 1950s Dr. Reginald Holman tested H2O2 on rats implanted with Walker 256 adenocarcinoma tumors. Their drinking water was replaced by a dilute solution of hydrogen peroxide. The optimal concentration was reported to be 0.45 percent, and complete disappearance of the tumors was reported to exist from fifteen to sixty days. (9)
In 1982 Winifred Wirth reported on the effective use of oral H2O2
in the treatment of laboratory mice infected with Ehrlich carcinoma.
Effectiveness was judged by the decrease in mortality and the delayed onset of
palpable tumor incidence. (18)
Hydrogen Peroxide and Radiation
It has been shown that there is a direct relationship between the oxygen content in tumor cells during radiation therapy and the effectiveness of the treatment. (10) Higher levels of oxygen produce better results. Hyperbaric oxygen chambers have been used to achieve better tumor oxygenation during radiation therapy. (2, 3) However, biological and physiological problems associated with the administration of oxygen at increased pressures plus the expense of the hyperbaric chambers themselves make this method of oxygenation somewhat impractical.
With the above difficulties in mind, a group of physicians decided to try using intra-arterial hydrogen peroxide as a source of oxygen along with radiation therapy in the treatment of 190 g individuals with advanced cancer. (1) The main criterion for the selection of cases for this study was that their tumors were either so very advanced or metastatic that they were considered poor candidates for any form of conventional therapy. Fewer than 10 percent of the subjects were expected to survive more than one year.
The individuals in this study showed the following overall survival for the five years of the study:
year one = 77 percent;
year two = 62 percent;
year three = 46 percent;
year four = 36 percent; and
year five =28 percent.
Patients with cancers of the head and neck, cervix, and bladder seemed to respond much better than would be expected under standard therapeutic
treatment. The authors of this study point out that their preliminary results suggest that the use of intra-arterial hydrogen peroxide can improve the effectiveness of standard radiation therapy for some types of malignancies.
Research and Information
The International Bio-Oxidative Medicine Foundation is an organization of physicians and scientists who are carrying out research on the effects of oxygen therapy or studying its clinical application. The foundation sponsors the annual International Conference on Bio-Oxidative Medicine and also produces the IBOM Newsletter. The studies presented at the IBOM conferences have done much to increase the credibility of such oxidative therapies as those using

In September 1984 Walter Grotz began publishing the ECHO Newsletter; this newsletter, written for the lay reader, presents information on hydrogen peroxide's many applications.
The following comments by Dr. Charles Farr are an appropriate summary for this section.
From the 2,500 or more references on hydrogen peroxide we have collected and reviewed, we have come to appreciate this physiological product as an extremely important molecule in metabolism. Hydrogen peroxide is produced by all cells of the body for many different physiological reasons. The granulocytes produce
H2O2 as a first line of defense against bacteria, yeast, virus, parasites, and most fungi. It is involved in any metabolic pathway which utilizes the many different types of oxidase enzymes. Hydrogen peroxide is involved in protein, carbohydrate and fat metabolism, immunity, vitamin and mineral metabolism or any other system you might wish to explore.
Our studies demonstrate a positive metabolic effect to
intravenous infusion of H2O2. Its ability to oxidize almost any physiological substance, in addition to producing increased tissue and cellular oxygen tensions, has proven it to have therapeutic value. (5)
Hydrogen peroxide is one of those substances that cries out for needed changes in FDA policy. Because it is a cheap, un-patentable chemical, no company is willing to invest the time and money needed to gain FDA approval.
H2O2 therapy is not illegal in the U.S., but it remains unapproved by the AMA and the FDA.
There is a growing number of physicians who are administering
hydrogen peroxide infusions in the United States. However, there are also many
cases where doctors have been confronted by medical boards and have been forced
to spend considerable time and money defending themselves. Some have had their
Hydrogen peroxide is one of the most widely researched and documented of all the alternative cancer therapies, with over five thousand studies published on its therapeutic effects. Yet it is still not approved by the FDA for use in treating cancer, arthritis, or other diseases.
Side Effects and Toxicity of H2O2
Hydrogen peroxide infusions are the foundation of all therapies offered at Hospital Santa Monica. In the past six years, the medical staff at HSM has administered over 30,000
H2O2 infusions,. without a single seriously negative reaction.
A review of the literature shows that to date over fifty papers have been published reporting the use of intra-arterial and intravenous infusions of hydrogen peroxide, representing hundreds of infusions, safely administered without serious side effects.
Occasionally a stinging or burning sensation occurs at the infusion site. Sometimes patients with smaller

In England, we’re big fans of tradition. Whenever that be putting on jubilant parties to celebrate Patron Saint’s days or stubbornly sticking to slightly more quirky practices, such as eating hot cross buns at Easter, we’re quick to remind ourselves of the quirks of British Culture even when we’re not sure how or why they’re in place. The Blue Plaques are a similar thing; we take them for granted, but how exactly did the whole of the country, and indeed the world, get into the habit of commemorating historical markers?
The Blue Plaque scheme first began in the 19th century in 1863 when it was proposed to the House of Commons by William Ewert PM and civil servant Henry Cole. As such, it is one of the oldest schemes of its kind in the world. The idea was later taken up by the now Royal Society of Arts (a body of notable fellows who find resolutions to the challenges of society) and erected its first plaque in 1867 to commemorate Napolean III. These early plaques were actually a chocolate brown, as making the colour blue was difficult to produce!
At the turn of the 20th century, the London County Council (which was the local government body for the County of London at the time) took charge and made the scheme much more focused. This phase of the schemes life was highlighted by some experimentation with plaque design, which ultimately led to the modern minimalist look that we now know, which was designed in 1938. The plaques produced an average of eight plaques each year, including a commemoration to Charles Dickens. The LCC was succeeded by the Greater London Council from 1965 to 1986. It began to incorporate not just individuals, but also buildings that held historical significance, such as the commemoration of the building where the Cato-street conspiracy was formed.
The early plaques were a dark brown as it was easier to produce. However, the very earliest plaques were blue, such as Napoleon III’s.
The scheme changed hands yet again, this time and currently, being run by English Heritage, a charity that is responsible for maintaining England’s historic buildings and places of interest. From this point, Blue Plaques began to have a broader reach and became more enshrined in English culture. The selection process also became broader and more regulated with a selected panel advising on who to elect. In order for a figure to qualify for a Blue Plaque, the said person must have been dead for at least twenty years, lived in London for a significant period, the building must still survive and not have been significantly altered, be seen as at the apex of their profession and their achievements must have made an impact on the public. Under English Heritage, the collection of plaques became more eclectic with some being made out to a wide range of people, such as Computer Scientist Alan Turing and guitarist and songwriter Jimi Hendrix.
Even when the scheme risked going under due to government cuts, it received a second wind thanks to many private donations and nominations. Nowadays there are plaques in all but three of Londons boroughs with some quirky recognised buildings such as the residence of famous clown Joseph Grimaldi. Competition for plaques continues to be exciting and with the new plaques for this year dedicated to classic comedian Charlie Chaplin and esteemed actor Sir John Gielgud. This thriving scheme has inspired many other countries to adopt a similar system, such as Australia and America to name a few.

Modern medicine is a beautiful thing. Until the last century, anything from the common cold to a scraped knee could be lethal for even the healthiest demographics. Today, we can go to a pharmacy for pills for all types of ailments. Since the breakthrough discovery of penicillin in 1928, the medical industry has developed exponentially. The question now is — where does it go in the future?
For a team of researchers, a study targeting blindness using a “bionic eye” is the next frontier. Phoenix 99 is the name given to the prototype in a recent animal study. Conducted by a team of researchers from the University of Sydney and the University of New South Wales, the trials involved sheep that underwent a surgical procedure to have a device implanted behind their retinas. The team connected the device to a wireless video feed via a small camera installed into a pair of sunglasses. The device relays the feed as electrical signals, which are processed by the optical nerve and transmitted to the brain.
Researchers were ecstatic to find that the sheep showed improved vision, paving the way for future human trials. “There were no unexpected reactions from the tissue around the device, and we expect it could remain in place for many years,” said Samuel Eggenberger, a biomedical engineer at the University of Sydney.
Devices like Phoenix 99 have the potential to change the world. Several companies, such as Second Sight and the Monash Vision Group, have similar retina implant technology either in development or already available in limited quantities. The impact would reach far and wide — more than 2 billion people worldwide have some vision impairment, leading to an estimated loss of $25 billion yearly in global productivity.
While the benefits are exciting, the technology is in its “infancy” and is very expensive. “I have no doubt that the technology has transformed the lives of patients who have been lucky enough to receive these implants,” said Dr. Diane Hilal-Campo, a New Jersey-based ophthalmologist. “Currently, however, the technology is limited, only allowing for the perception of light and shadows, and, to some extent, shapes.” | <urn:uuid:77e55f50-6853-46cb-bed6-f0ffe7d73b3d> | CC-MAIN-2023-06 | https://garden-and-health.com/bionic-eye-improves-sheep-vision-opens-path-to-human-trials/ | s3://commoncrawl/crawl-data/CC-MAIN-2023-06/segments/1674764500628.77/warc/CC-MAIN-20230207170138-20230207200138-00476.warc.gz | en | 0.964164 | 443 | 3.203125 | 3 |

The rock shrimp (Sicyonia brevirostris) is a deep-water cousin of pink, brown and white shrimps. But due to its hard exoskeleton or shell, it did not have the large market and popularity as its cousins until a machine was invented that would split the tough shell and devein the shrimp. Now rock shrimp are widely available fresh or frozen, whole, headless, shell-on, peeled, round, split or deveined.
Similar to deep-sea lobster, rock shrimp live, spawn and are harvested in 120 to 240 feet of water. Harvesting is done with reinforced trawl nets throughout the year.
Rock shrimp derives its name from the rock-like hardness of its shell and can easily be mistaken for a miniature lobster tail. Rock shrimp, which tastes like a lobster, is actually a member of the shrimp family. The texture of the rock shrimp leans toward the lobster, while the palate appeal is more like a shrimp.

Firm texture, similar to Spiny Lobster with sweet, distinct flavor. Low fat.
Shrimp, Spiny Lobster.
Two pounds of raw tails will yield one pound of cooked, peeled and deveined rock shrimp.
• Remember to purchase seafood last and keep it cold during the trip home.
• Rock Shrimp are sold by "count" (number of shrimp per pound) with the largest size about 21-25 per pound.
• Rock Shrimp should have a mild aroma (similar to the ocean), tightly adhering shells and firm flesh.
• Store them in the coldest part of your refrigerator at 32° F. and use within two days, or freeze at 0° F. for up to six months.
• To clean rock shrimp use one of these methods:
• For broiling in the shell: Place the rock shrimp on a cutting board, dorsal side down and the swimmerets up. With a sharp knife, cut from the base of the tail to the other end, but not through the shell. Gently spread the meat apart to expose the sand vein and wash under cold running water.
• To remove the shell: Use sharp kitchen scissors to snip through the back, down the middle and to the base of the tail. Gently separate shell from flesh and remove sand vein by rinsing under cold running water. This method is recommended for boiling or sauteing.
• Keep raw and cooked seafood separate to prevent bacterial cross-contamination.
• After handling raw seafood thoroughly wash knives, cutting surfaces, sponges and your hands with hot soapy water.
• Always marinate seafood in the refrigerator.
• Discard marinade; it contains raw juices which may harbor bacteria.
• When marinade is needed for basting reserve a portion before adding raw seafood.
• Rock shrimp cook more quickly than other shrimp.
• To boil: Drop in a pot of boiling salted water, stir, and after 35 seconds pour into a colander and rinse with cold water.
• To broil: Place 4 inches from the source of heat for 2 minutes or until the meat turns opaque.

Nearly half of the children can suffer from a tooth injury during their childhood. When a permanent tooth gets damaged, it hinders blood supply and root development of the tooth. This results in the formation of a dead tooth.
A technique is carried by dentists to encourage root development, known as apexification. This procedure does not replace the lost root tissue from the injury, but in rare cases it can lead to abnormal root development.
A Research Study
A clinical trial was conducted by the Songtao Shi from the University of Pennsylvania and Yan Jin, Kun Xuan and Bei Li of the Fourth Military Medicine University in Xi'an, China. They published their work in the journal of Science Translational Medicine. They suggested a new therapy to treat such injuries in children. Root re-development can occur by using stem cells extracted from the patient's baby teeth.
Professor Songtao Shi, a professor in the Department of Anatomy and Cell Biology in Penn's School of Dental Medicine states that this stem cell therapy will bring back sensation in the teeth of the children. If you provide them with a warm or cold stimulation, they can feel it. Studies also show that this therapy is safe for three years. A further analysis will be required to study its long-term safety and effectiveness.
Shi and his colleagues are working from a decade to study dental stem cells, also known as human deciduous pulp stem cells (hDPSC). They have studied their working and safety concerns when used to re-grow dental tissue or pulp of a tooth.
The Phase I trial was conducted in China where 40 children were enrolled in the study. Each child had injured one of his/her permanent incisors and still had baby teeth. Thirty of them were assigned to hDPSC treatment and 10 were undergone control treatment, i.e., apexification.
The group of children, who received hDPSC treatment, had their tissue extracted from their healthy baby tooth. The stem cells present in the pulp of the healthy baby tooth were initially allowed to reproduce in a laboratory culture, and then the grown mass of cells was implanted into the injured tooth.
Observations and Results
- Upon follow-up of the therapy, the researchers found that patients who received hDPSCs had higher signs of root development and presence of thicker dentin, than the control group of children. Blood flow had also increased after the human deciduous pulp stem cells treatment.
- Initially, patients felt little sensations in their tissues. A year after the procedure, those who received the hDPSC therapy had regained some sensations. Scientists also found some immune-system components in their tooth. They could not investigate any safety concerns. But in the control group, sensations were not improved.
The researchers had the opportunity to directly examine the tissue grown after the stem cell therapy. When a patient reinjured his tooth, scientist extracted it and studied the dental pulp. They found that the implanted stem cells had regenerated into different components of the dental pulp. They developed dentin, a hard mass of tissue present under the enamel and also contained connective tissue and blood vessels in their dental pulp.
This therapy was further adopted by clinicians to treat different tooth injuries in children. This technique is proven to be highly beneficial in children as there does not exist an immune rejection risk. They are hoping to get an FDA approval to conduct clinical trials using hDPSCs studies in the United States.
This therapy cannot be used for adults due to the absence of hDPSCs. Professor Shi and his colleagues have started to test the use of allogenic stem cells, or cells donated from another person, to regenerate dental tissue in adults. They believe that hDPSCs have a potential to treat certain systemic diseases such as systemic lupus erythematosus also.
This research was supported by the National Key Research and Development Program of China, the Natural Science Foundation of China and a pilot grant from Penn Dental Medicine. | <urn:uuid:a79b6f5b-a7ac-4672-8f21-d6674e0765f7> | CC-MAIN-2019-18 | https://www.diseasefix.com/page/regrowing-dental-tissue-with-stem-cells/5214/ | s3://commoncrawl/crawl-data/CC-MAIN-2019-18/segments/1555578733077.68/warc/CC-MAIN-20190425193912-20190425215912-00338.warc.gz | en | 0.977234 | 815 | 3.46875 | 3 |
As we covered on Part 1, bee colonies in Western countries have been declining at historically unprecedented levels, with massive hive die-offs in in the U.S. and Québec. Beekeepers have reported colonies collapsing accompanied by a “lack of dead bees”. The phenomenon in which disoriented honeybees die far from their hives has been coined “Colony collapse disorder” or (CCD).
Dr. Jennifer Sass, a senior scientist with the health group at the Natural Resources Defense Council (NRDC), says that the Bromenshenk/Army study fails to ask the underlying question “Why are colonies dying? Is it because they’re getting weak? People who have HIV don’t die of HIV. They die of other diseases they get because their immune systems are knocked off, making them more susceptible.”
Fortune notes that Bromenshenk’s study acknowledges that the research does not “clearly define” whether the concurrent virus and fungus, which were found in all the afflicted bee samples, is “a marker, a cause, or a consequence of CCD.” It also notes uncertainty as to how, exactly, the combination kills the bees.
“We’re even concerned that based on this [Bromenshenk's study], beekeepers will use more pesticides trying to treat these viruses,” says Dr. Sass at NRDC.
According to Fortune, the NRDC sued the Environmental Protection Agency two years ago after it failed to release Bayer’s underlying studies on the safety of its neonicotinoids — a class of neurotoxins that kills insects by attacking their nervous systems. Under pressure, the EPA finally relented and NRDC researchers are now allowed to research the Bayer studies.
“The EPA has based its approval of neonicotinoids on the fact that the amounts found in pollen and nectar were low enough to not be lethal to the bees — the only metric they have to measure whether to approve a pesticide or not. But studies have shown that at low doses, the neonicotinoids have sublethal effects that impair bees’ learning and memory.” The USDA’s chief researcher, Jeff Pettis, told Fortune in 2008 that pesticides were definitely “on the list” as a primary stressor that could make bees more vulnerable to other factors, like pests and bacteria.”
Dina Spector with Business Insider cites David Hackenberg, former president of the American Beekeeping Federation, as part of a leading team of beekeepers and experts who claim that neonicotinoids are the cause of CCD. “Imidacloprid, the most widely-used neonicotinoid, is different than other insecticides because it enters the pollen and nectar of the plant, not just the leaves. Hackenberg describes bees under the influence of neonicotinoids as ‘drunk’ and ‘disoriented’. And, if neonicotinoids affect the honey bees’ ability to remember how to get back to their hive, then it makes sense why the dead bodies are never found.”
A researcher in Canada has already exposed Bromenshenk’s theory as nonsense, claiming that the virus and fungus under suspicion have been around for more than 20 years. “If bees weren’t disappearing 20 years ago, why are they now?” says Jim Doan, a bee farmer.
Over a decade ago, Bayer again attempted to blame CCD on a non-man made cause, such as a virus, fungus, or parasite. In 1999, after millions of honey bees exhibiting the same CCD symptoms began to disappear, the French government implemented a nationwide ban an imidacloprid-based pesticide used to dress sunflowers. And Bayer denied the connection, claiming only sublethal doses of Imidacloprid make it into the nectar and pollen that bees consume and carry back their hives.
Business Insider mentions Dr. Diana Cox-Foster, professor of entomology and insect biochemistry researcher at Pennsylvania State University who is part of a research team that has done extensive toxicology sampling of bees, wax, and pollen taken from hives that experienced dead-outs associated with symptoms of CCD. Her team found that on average, anywhere from 6 to 35 different chemicals compounds were in a single hive.
“The pesticides bees are bringing in from pollinating represent all different chemicals that we use in agriculture, yards, even inside our homes,” said Cox-Foster. And as Spector notes, in combination, some of these mixtures of chemicals may cause increased toxicity to bees that are not apparent when found individually.
Apparently, scientists are not yet able to implicate any single chemical — or combination of chemicals — as the sole cause of CCD. Spector claims there is a general consensus that bees are suffering from an assault of many different factors that put together, weaken the bee’s immune system and make it susceptible to viruses.
More research and federal funding are needed. Considering that the honeybee pollinates a third of all the food we eat, you’d think society at large would not tolerate allowing lawmakers and federal regulators to put corporate interests before the health and safety of the public. | <urn:uuid:ee3d2b90-98d3-43a8-9fa4-778d151dd003> | CC-MAIN-2014-41 | http://blog.friendseat.com/colony-collapsed-disorder-bayer2/ | s3://commoncrawl/crawl-data/CC-MAIN-2014-41/segments/1410657124236.90/warc/CC-MAIN-20140914011204-00074-ip-10-196-40-205.us-west-1.compute.internal.warc.gz | en | 0.950031 | 1,096 | 3.03125 | 3 |

As is the case with many structures in post-war Germany, one church is realizing it still has a connection to the Nazi party.
The Jakobskirche village church in the small town of Herxheim am Berg holds a bell that created controversy after it was discovered to be emblazoned with Nazi insignia.
The church is 1,000 years old and thus was standing throughout the country’s dark period during World War II and the Holocaust. The bell was reportedly added to the church in 1934.
The bell was found to bear a swastika under the phrase “All for the Fatherland, Adolf Hitler.” | <urn:uuid:50a22efd-9071-436c-b448-5dd59721f2cd> | CC-MAIN-2019-47 | https://kelseybdriscoll.com/2017/06/29/village-grapples-with-church-bell-emblazoned-with-nazi-insignia/ | s3://commoncrawl/crawl-data/CC-MAIN-2019-47/segments/1573496669809.82/warc/CC-MAIN-20191118154801-20191118182801-00351.warc.gz | en | 0.981112 | 133 | 2.5625 | 3 |
Spheres of influence. The educational aspirations of favela youth in Rio de Janeiro
This is an ethnographic study about the factors that intervene in the Brazilian favelas’ youth’s decision to pursue post-secondary education. The fieldwork was performed over the course of years 2009 and 2013 in the Rocinha favela of Rio de Janeiro. Results indicate that there are three types of social factors that play an interactive role in such decision: the family, the community environment and the outside world. These three socialization spaces influence the individuals (young men and women) with different intensity. The extensive family constitutes the inner sphere and the most powerful determinant for the future educational aspirations of the youth. The views they have in the present reflect in good part what their family members taught them to believe. The second sphere, the community environment, covers the inner sphere and it is mainly formed by peers, family friends and community organizations, many of which include role models. The third and outer sphere is the outside world provides the youth with alternative models as well as with information about a wide variety of lifestyles. Educational opportunities that favela youth have in their lives depend on the availability, cost and quality of schools (secondary and post/secondary institutions), but also on their own motivations to seek opportunities to study for a better future. The outcome of the interaction of these factors in the individual is a set of typologies of attitudes toward social inequality and social mobility (varying from “pessimistic” to “optimistic”) and education (varying from “effective” to “undesired”). Such typologies contribute to the definition of future educational plans. | <urn:uuid:5ef04ea2-9626-4858-914c-f3bc38ba7a67> | CC-MAIN-2023-23 | https://digitallibrary.tulane.edu/islandora/object/tulane%3A121690 | s3://commoncrawl/crawl-data/CC-MAIN-2023-23/segments/1685224656963.83/warc/CC-MAIN-20230610030340-20230610060340-00024.warc.gz | en | 0.957159 | 350 | 2.546875 | 3 |
The state of the nation report detailed the conservation efforts put forth in conserving the natural environment.
With 72 percent forest cover Bhutan is the only country that is carbon neutral and Bhutan is beginning to be recognized as the only carbon negative.
“These are the reasons why Bhutan is being recognized internationally as a role model, which was clearly expressed during COP-21 when countries committed to the Paris Agreement,” the report said.
The PM in the report expressed gratitude to the parliament for ratifying the Paris Agreement and said Bhutan is looked up as a champion of the environment and climate change and it befits Bhutan to be a group that works for a global cause.
The report said the Paris agreement seeks to keep the rise in average global temperature well below 2 degree Celsius, compared with pre-industrial times, and individual countries made voluntary pledges to curb emission of green-house gases.
“Notorious emitters of greenhouses gases too committed to reduce their green houses gas emissions and are actually taking the lead in investing in renewable or clean energy,” the report said.
However, the report said that environment it is not just confined to trees, it is also about water and air and the National Environment Commission Secretariat has been gradually working to increase coverage of air quality being monitored.
Over the coming year, two new additional stations in Darla and Chelela will be established.
These stations will provide data and information on local air and also transboundary air pollution to gain deeper understanding on the pathways of the winter haze that affects large parts of the country, especially along the southern belt of the country.
A revised vehicle emission standard and ambient air quality standards will also be issued.
According to the state of the nation report Bhutan has over 5,400 species of plants, including 300 species of medicinal plant, some hardy species thriving even at 3,700 m above. While Bhutan has one also of the richest stocks of orchids in the world with 396 species, 82 are unique to the country. Bhutan also boasts of 48 of the 1,000 species of Rhododendrons found worldwide.
As part of His Majesty the fourth Druk Gyalpo’s birth anniversary celebration, the report said that His Majesty commended that a flower exhibition should be held where on April 1, 2015, Her Majesty the royal grandmother, Ashi Kesang Choden Wangchuck, cut the ribbon of the Himalayan Kingdom’s floral history. The nation had its first Flower Exhibition at the Ugyen Pelri palace in Paro.
The report stated that apart from the beauty that was exhibited His Majesty had other objectives that the exhibition was envisioned to inspire appreciation for beautiful spaces, foster community vitality and encourage the growth of a vibrant entrepreneurship in floriculture.
The third flower exhibition was held in Thimphu from June 5 to June 11 this year.
In an effort towards maintaining the forest and environment, the government has designated several areas as parks and biological corridors. Since this requires financial support and the government has established Bhutan for Life (BFL) of US$ 45 million which will be used to maintain the protected areas.
The fund raising is almost complete and the government will launch BFL on November 11 this year.
The government has also established Green Bhutan as Government owned corporation to look after the environment.
Drawing inspiration from His Majesty’s speech during the first flower exhibition in 2015, Green Bhutan Corporation Limited was established to promote clean and green environment.
As per the state of the nation report, GCBL is mandated for landscaping, urban greening, plantation and floriculture among others, which will promote tourism. It is expected that 500 people will receive jobs in this corporation.
Meanwhile the report also saw the PM congratulating the CSOs who work to keep the environment clean. | <urn:uuid:fe83bbc4-2e92-493d-b68e-f14c345d26af> | CC-MAIN-2017-39 | http://thebhutanese.bt/revised-vehicle-emission-standard-and-ambient-air-quality-standards-to-be-issued/ | s3://commoncrawl/crawl-data/CC-MAIN-2017-39/segments/1505818687837.85/warc/CC-MAIN-20170921191047-20170921211047-00153.warc.gz | en | 0.963015 | 793 | 2.59375 | 3 |
Space Debris Still a Growing Problem

Space debris has long been cause for concern. In the mid-1990s, the United Nations deemed it a significant enough risk to implement mitigation measures aimed at reining in the proliferation of space debris. (New updated measures were re-introduced in June 2007.) Mitigation held the density of space debris to constant levels throughout the 1990s, but in recent years, the number of fragments has begun to climb again. There are now more than 150 million pieces floating in space, most measuring less than 2 inches across.
Space debris mostly consists of a mix of discarded objects: spent rocket stages, defunct satellites, fragments from explosions of various space equipment, paint flakes, dust, even the occasional glove, camera, or jettisoned garbage bags. Most of these are at low enough altitudes that they drift through space for awhile between re-entering the atmosphere, often burning up in the process.
However, the greatest concern is debris that results from explosions, such as when rockets or spacecraft with unspent fuel collide with other objects, thereby producing a great number of fragments. According to Geoffrey Forden, an MIT physicist, the Chinese action produced more than 2300 pieces larger than a golf ball, and over 35,000 pieces larger than 1 centimeter. We are in danger of a runaway escalation of space debris, he said.
The density of debris is fast approaching supercriticality, according to David Wright of the Union of Concerned Scientists, which maintains a satellite database tracking all those bits of debris. This situation could result from the destruction of an orbiting object into many smaller fragments of debris, initiating a chain reaction as that debris collides with other satellites in nearby orbits, breaking them into fragments in turn and compounding the problem further.
At high altitudes, the debris can stay in orbit for decades, accumulating to the point where there is a much higher risk of collisions with satellites. In fact, it may already be too late: Wright cited a 2006 study by NASA’s Orbit Debris Program that found certain parts of space particularly the 900 to 1000 km band, or Lower Earth Orbit (LEO) have already reached supercritical debris densities. NASA estimates that an active satellite in LEO will collide with a piece of debris larger than 1 centimeter every five to six years.
With their high speed in orbit, even fairly small pieces of debris can damage or destroy satellites in a collision, said Wright. Orbital speeds in LEO are typically greater than 7 kilometers per second, 30 times faster than a jet aircraft, and the relative speed of a piece of debris approaching a satellite in an intersecting orbit may be 10 km per second or higher, said Wright.

Pemphigoid gestationis (PG), also known as gestational pemphigoid or herpes gestationis, is an autoimmune skin disorder associated with pregnancy. Signs and symptoms of the disorder typically present during the second or third trimester of pregnancy, but it may occur at any time during pregnancy or anywhere up to six weeks after giving birth. Although the signs and symptoms are variable, a red, itchy rash with blisters is common. The rash may occur in different parts of the body, but usually develops near the belly button and/or the arms and legs. The condition is caused by the production of antibodies that attack the person's body, leading to damage and consequently blister formation. Treatment generally involves systemic corticosteroids.
