A spring bloom of phytoplankton lingered in the Atlantic Ocean off the coast of Iceland in early June, 2014. The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Aqua satellite captured this true-color image on June 5. At that time, swirling jewel tones of a vast bloom were visible between banks of white clouds.
According to the Icelandic Ministry of Fisheries and Agriculture, phytoplankton blooms around Iceland usually occur in early spring and fall. The spring bloom is driven by longer daylight and the warming of surface layers. This leads to stratification of the waters, and allows the phytoplankton to stay in the surface layer and reproduce. By summer the huge numbers of phytoplankton in the blooms decreases nutrients, and the numbers of the organisms begins to plummet.


Burgoyne Diller: The Third Dimension features important sculpture and wall reliefs as well as drawings for three-dimensional works spanning Diller’s entire creative career. Burgoyne Diller is recognized as among the most significant and influential twentieth-century artists devoted to geometric abstraction. As early as the 1930s, he was regarded as a leader of the avant-garde in American art and a forefather of the 1960s minimalist movement.
Upon exploring Burgoyne Diller’s oeuvre, it is apparent that the third dimension was a lifelong obsession which played a significant role in his creative process. Surprisingly, though, the sculptural aspect of Diller’s art has not been sufficiently examined and, as a result, there are misconceptions of Diller as a principally two dimensional artist following in the tradition of Piet Mondrian. This exhibition illustrates Diller’s ongoing preoccupation and extraordinary accomplishments in the realm of sculpture.
During the early 1930s, Burgoyne Diller studied at the Art Students League. In 1934, he was employed as an easel painter by the Public Works of Arts Project (PWAP). In 1935, he was appointed Director of the New York City WPA/FAP Mural Division and in 1937, was a founding member of the American

Serinus Canaria Domestica
The Domestic Canary, often simply known as the canary, (Serinus canaria forma domestica) is a domesticated form of the wild Canary, a small songbird in the finch family originating from the Macaronesian Islands (Azores, Madeira and Canary Islands).
Canaries were first bred in captivity in the 17th century. They were brought over by Spanish sailors to Europe. This bird became expensive and fashionable to breeding in courts of Spanish and English kings. Monks started breeding them and only sold the males (which sing). This kept the birds in short supply and drove the price up. Eventually Italians obtained hens and were able to breed the birds themselves. This made them very popular and resulted in many breeds arising and the birds being bred all over Europe.
Habitat & Food:
Greens are a staple, such as chickweed, seedy (lawn type) grass heads, dandelion, carrot, broccoli, Brussels sprouts, and apple. There are many recipes for soft food that include ingredients such as hard boiled egg, gelatin, bread crumbs, or biscuit crumbs. A protein-rich soft food, together with sprouted seed, is the fundamental diet of canary chicks.


LORI DUNN SCRATCHBOARD ART
promoting conservation through artistic efforts
What is Scratchboard?
Scratchboard art is a form of direct engraving on a specially prepared board. The boards consists of three layers of material. The base is hardboard that has a layer of white kaolin clay applied to it. The clay is then sanded smooth and a layer of black ink is applied over top. The image is etched one “scratch” at a time using an extremely fine tool such as a scalpel or exacto blade. The black is removed to reveal the white clay beneath.
These clayboard engravings are considered by many artists to be one of the most difficult of mediums to master. It takes a very steady hand to maintain the correct pressure required to etch each fine line to a particular depth. Mistakes are not easily corrected – they cannot be erased or painted over! It is one of the only forms of two dimensional media that is subtractive as material is removed rather than added. Artists must work in reverse of classical artistic training in that they are rendering highlighted areas only. Tonal variations are acheived by the depth of etching as well as how much surface area is removed.
Many hours are spent on each scratchboard artwork and they may take months to complete. Lori Dunn uses professional grade clayboards that are completely archival, of museum quality and highly resistant to fading from sunlight. Finished works are sprayed with a UV resistant varnish to further protect the image.
Scratchboard produces unique works of art with a level of realism and detail that is unsurpassed by many other media. The absorbent clay can be coloured afterwards using specialized inks or paints but many people, like myself, prefer the simplicity and beauty of the black and white image.

“Adaptation is critical for Belize. Global warming has increased the number and intensity of coral bleaching episodes resulting in irreparable harm to our reefs. The marine resources that rely on the ecosystem provided by the largest barrier reef in the western hemisphere are feeling these effects and are either declining or migrating to more hospitable environments. Sea level rise is increasing erosion on the mainland and many of our offshore islands, “ Belize’s Minister of Forestry, Fisheries and Sustainable Development, Lisel Alamilla said Thursday.
Speaking at the high-level session, she said during the annual spring tides, the municipal airport in Belize City is inundated twice a day rendering the airport inoperable and disrupting domestic air transport.
“This is a new phenomenon for us. Droughts and heat waves are adversely affecting agriculture and poultry production and threatening our food security. Intense rainfall episodes which are now occurring annually are disrupting transportation, washing away bridges and undermining roads,” she said adding that adaptation comes at a great cost to her country.
If the international community fails to undertake ambitious actions to limit global warming to below 1.5 degrees Celsius, the impacts of climate change to Belize will be significantly greater and more extensive, she told delegates attending the conference.
Belize is also prepared to reduce its greenhouse gas emissions which at last inventory shows that over 95% of emissions came from the land use and forestry sectors. Belize has the highest percent of natural forest cover in the Mesoamerican region.
Over a 30 year period from 1998 to 2010, historic baseline of forest cover loss was estimated at an annual rate of 0.6 percent but the past two years has seen a significant increase in deforestation rate.
To mitigate this threat, Alamilla said the government is adopting policy measures for responsible land-use and development.

What is Thread Group in Java?
ThreadGroup is a class that provides information about a thread group. It helps to get the list of active threads in a thread group and to set the uncaught exception handler for the thread.
Ever since setUncaughtExceptionHandler (UncaughtExceptionHandler e) was added in Java 1.5, it serves the purpose to set exception handler and ThreadGroup becomes obsolete and no longer used.

Is Sustainability Our Mission?
Pope Francis released his encyclical, Laudato Si’: On Care for Our Common Home, during the spring of 2015, calling people of the world together to enact “swift and unified global action” to counter environmental degradation. Sustainability, in its most basic definition, means the ability to continue on indefinitely. For humans, it typically means to live in a manner that is cognizant of the interconnectedness of economy, society and environment.
Sustainability is an urgent institutional focus for Niagara University. In 2012, NU signed the American College & University Presidents’ Climate Commitment, which formalizes the university’s plan to eliminate the campus’ net emissions of greenhouse gases. The sustainability effort is also about education, and NU has integrates sustainability into its freshman seminar, “Niagara University Beginnings.” During this course, students are assigned to read and evaluate selections from this important papal document, Laudato Si’.
On Nov. 18, 2015, faculty and staff from several Niagara University departments joined the Rev. James J. Maher, C.M., NU's president, to discuss sustainability from a number of perspectives. Nearly 100 students attended the forum in order to learn more about how global sustainability initiatives impact the Niagara campus and what steps the university is taking to address sustainability.
Niagara University, which offers a major in environmental studies, has been lauded numerous times for its dedication to sustainability. It is annually featured in The Princeton Review’s Guide to Green Colleges and its B.

NASA launches rockets from Virginia to study upper level jet stream
Published 12:00 am, Tuesday, March 27, 2012
ATLANTIC, Va. -- After several delays, NASA has launched five rockets from Virginia that are part of a study of the upper level jet stream.
The rockets began blasting off just before 5 a.m. Tuesday from NASA's space center on Wallops Island. Bad weather had postponed other planned launches last week.
The Anomalous Transport Rocket Experiment (ATREX) will help scientists understand the jet stream, which is located 60 to 65 miles above Earth's surface.
After launching, the rockets released a chemical tracer to form white clouds that allowed scientists and the public to visualize the winds.
A NASA news release says the launches and clouds were reportedly seen from as far south as Wilmington, N.C.; west to Charlestown, W.Va.; and north to Buffalo, N.Y.


Coues’ Rice Rat or Oryzomys couesi is a semi-aquatic rat that occurs between north-western Colombia, Central America, Mexico, and southern-most Texas. This rat was first scientifically described in 1977 by Edward Alston.
Coues' Rice Rat amongst vegetation
Coues’ Rice Rat is a large – medium sized rat that can have a head to body length of about 98 – 142 mm. It weighs about 43 – 82 grams. It has coarse fur that is reddish to buff, but the colour of the fur becomes paler towards its sides. Its underparts are buff to white. Compared to the marsh rice rat, it has shorter and brighter fur. Coues’ Rice Rat also has a long tail that is brown above and white or light brown below. Its feet are stout and long, and there are ungual tufts present on its digits.
This rodent is usually found in wet habitats. These habitats include shrubland, drier forests, and marshes. At night time, it builds nests constructed of vegetation which are suspended amongst reeds that are about a metre above the ground. As it can be found in wet habitats, it comes as no surprise that Coues’ Rice Rat is a good diver and swimmer. However, it can also climb in vegetation. It is an omnivore which eats insects and seeds.
Two Central American rodents - Coues' Rice Rat is at the top
According to the IUCN, the Coues’ Rice Rat is categorised as being of “Least Concern” because it is a common species that can be found in many protected areas. However, drainage of wetlands and the destruction of its habitat may threaten some of the Coues’ Rice Rat’s population. However, in many areas it is so common that it is considered a plague.

Pakistan was declared an independent state through the "Independence Act" of August 14, 1947 by which the India of the Muslims has been seperated from the India of the Hindus. Pakistan's West is bordering on Iran und Afghanistan, its North on Afghanistan and India (Kashmir), its East on India and its South on the Arabische Sea. In 712 Islam came into the area of Pakistan. In the 11th century Lahore became a significant Islamic center. Under the Moguls Akbar, his grandson Jahangir and Jahangir's art-loving wife Nur-Jahan (meaning "Light of the World) Lahore gained further cultural and economic importance. Nur-Jahan was mainly responsible for the accruement and the development of the carpet culture and production. Inspired by the Indo-Persian carpet culture an independent style has emerged: the "Mogul-Rugs". Also in the South of the country, in Karachi and Peshavar, high quality rugs have been made. Despite Pakistan's introduction of the decimal system in 1976 it is still common to measure the fineness of Pakistani rugs in knots per inch. Pakistani rugs are mostly made with the Persian Senneh knot. Altogether one can say about Pakistani rugs that they are often being underrated in their quality and that the value for money is often better than with Persian rugs.


How is a beach built up? Of course we know that the Ogunquit River helps feed the sand off shore as the tide goes out.
With the sand offshore, what happens next? This diagram shows how the sand moves in the water, on the beach and behind the beach.
Large waves occasionally move sand towards the beach and when they do, they move large quantities.
Closer to the beach the sand movement is an every day affair and in the breaker zone huge quantities are moved almost every hour. As waves move sand towards the beach, gravity and back-wash move some of it back again.
Gradually, more sand is deposited on the beach, although in big storms, the large waves and rain can take a lot of beach sand back out in the ocean where the process can begin slowly begin again.
Next time you walk on the beach, think about this process that has given us one of the finest beaches in Maine.


The first ever trial of self-driving cars on Britain’s busy roads will take place later this year.
Researchers from the Oxford University have been working with Japanese multinational automaker Nissan on the technology and have already tested a car on a private road in a science park.
Trials will soon take place on lightly used rural and suburban roads, The Telegraph reported.
Scientists have adapted a robot car, which is capable of running on a predetermined familiar route, although the driver can reassert control by tapping on the brakes. The trials of the driver-less cars and a pledge to pump another 500 million pounds into electric vehicles are the cornerstone of the U.K. government’s strategy. Internet search giant Google has already tested driver-less cars on 1,60,934 kilometres of roads in San Francisco, the report said.
These cars have been left to drive themselves using cameras, radar and laser sensors.


President Donald Trump signed two proclamations Monday, Dec. 4, dividing the Bears Ears and Grand Staircase Escalante national monuments and reducing them in size.
The move was expected, after Interior Secretary Ryan Zinke conducted a review of all presidential monument designations dating to the Clinton Administration.
Bears Ears National Monument
Zinke did not recommend any monuments be rescinded. Instead, he recommended some be reduced in size to more closely align with the American Antiquities Act of 1906, which grants presidents designation authority.
The Antiquities Act limits the area of new monuments to "to the smallest area compatible with proper care and management of the objects to be protected."
The AMA believes that previous presidents overstepped their authority under the act and designated much larger swathes of land as monuments, sometimes encompassing millions of acres. Such sweeping designations may jeopardize opportunities for responsible motorized recreation.
Under the president's plan, Bears Ears National Monument will be modified to two units named Shash Jáa, Navajo for Bears Ears, and Indian Creek, encompassing a total of 228,784 acres of land.
Bears Ears was originally designated by President Barack Obama in 2016 to encompass nearly 1.5 million acres, including a patchwork of federal, state and private land.
Grand Staircase Escalante National Monument will be modified to three units encompassing a little more than 1 million acres. Grand Staircase was originally designated in 1996 by President Bill Clinton.
Presidents have modified the boundaries to remove lands from monuments 18 times in the past. The most significant reduction occurred in 1915 when President Woodrow Wilson halved Mount Olympus National Monument, which is now a national park.

Data theft is when someone takes data that is stored on another’s computer or data storage unit. A large part of company business communications and property is stored as data, so data theft is on the rise.
Employers must keep a vigilant eye on the decisions of the state and federal courts in regard to the monitoring of their employees. Otherwise they risk violating privacy rights and this can be a costly mistake.
For the purpose of this web site, data storage is the saving of any data that may be made and stored electronically.

|Target Audience:||Perl programmers from all disciplines who are familiar with the basics of Perl's control flow, string handling, and simple data structures (scalars, arrays, hashes).|
This full-day tutorial will introduce beginner and intermediate Perl programmers to the full functionality of Perl's regular expressions.
The morning sessions explore the principles and mechanisms underlying all Perl regular expressions. You'll see how the highly compact syntax of Perl patterns controls a built-in pattern-matching "engine", and learn how to design and construct Perl regexes to drive that engine efficiently. We'll also look at the four principal uses of regexes in Perl, discussing a number of uniquely Perlish regex "idioms". By lunch time, Perl's regexes will no longer seem like a mystery wrapped in an enigma wrapped in line-noise.
In the afternoon we will look at the more advanced and powerful features of Perl regular expressions such as code embedding, user- defined assertions, regex recursion, and backtracking control. These high-end features are not covered in most Perl textbooks or classes, yet understanding and being able to apply them is essential when dealing with large, real world data sets. During the class we will work through several everyday, yet challenging, problems in information processing and see how the Perl's regular expression mechanism can be tamed and harnessed to solve them. By the end of the day, the full (and surprising) power of Perl's regular expression will be at your command.

What Are Pack Rats? Commonly referred to as pack rats, woodrats are small rodents with hairy tails, fine fur, and large ears. They are named for their strange habit of gathering glass, jewelry, and ot her shiny objects to hoard in their nests. Do Pack Rats Hibernate? Woodrats are also known for their building skills. Their complex nests are created from sticks, bark, rocks, bones, leaves, and urine. These elaborate structures are needed because a pack rat doesn’t hibernate. The pests are active year-round, which is why they must insulate themselves when temperatures drop and keep food caches nearby. Pack Rat Damage Pack rat nests can become massive, foul-smelling homes for other pests like cockroaches, rats, and spiders. Additionally, pack rats may gnaw on wires and rip open furniture or pull apart carpets in search of nesting material. Exclusion & Prevention Rodent-proofing houses will generally keep these pests out. Homeowners should seal cracks and plug any gaps in screens, paying special attention to favorite spots like crawl spaces, basements, and attics. In order to safely remove a pack rat infestation, contact the professionals at Critter Control.

The increasing importance of a knowledge of dielectric constants of substances is shown by the large number of measurements that have appeared in recent literature- Several methods have been used in making these measurements, but probably the most precise ate the methods based on the heterodyne beat principle. This apparatus is designed to measure substances that are non-conducting. The condition of constant capacitance in the measuring circuit is the principle of the apparatus and is detected by the beat note between a fixed crystal radio frequency oscillator and oscillations generated by a variable oscillator. Otto and Wenzke (6) have used this principle with extremely precision results. ~e condition of maintaining constant capacitance in the measuring circuit is the most commonly used method in such measurements.

Reexaming the silver screen detective Charlie Chan. A new book looks at the caricature and the real-life man he was based on.
Hollywood’s Chinese caricature detective Charlie Chan was a big hit in the 1930s – with his “ah-so” aphorisms – and reviled a generation later as Exhibit A of anti-Asian racism on the big screen. A kind Stepin Fetchit in yellowface.
Now, a mainland China-born, Chinese scholar immigrant to the USA is looking back at Charlie Chan and saying hold on, this guy’s kind of cool. And giving us the whole history of the Charlie Chan story.
Some big Chinese Americans are not buying it. We’ll hear that, too. We’re looking again at the “honorable detective,” Charlie Chan.
Yunte Huang, professor of English at the University of California, Santa Barbara. His new book is “Charlie Chan: The Untold Story of the Honorable Detective and His Rendezvous with American History.” You can read an excerpt.
Frank Chin, Chinese-American author and playwright. He is considered one of the pioneers in Asian American theatre. His play “The Chickencoop Chinaman” was the first by an Asian-American to be produced on a major New York stage. He’s author of “Gunga Din Highway” and “Donald Duk.”


The object of legal education is to equip the law student with virtues and skills necessary for a good lawyer such as Honesty, Courage, Industry, Wit, Eloquence, Judgement, and Fellowship. Thus the skills of Lawyers were used to help the poor and needy to pro9ve their lawful and truthful claims before courts of Law. Due to globalization today the Scope of Legal Education became a multi-faceted one. Therefore, a lawyer today cannot stop his work within the Court Hall. He has to perform his role both at the municipal as well as international levels. The growth of Science and technology widened the ambit of Legal education to new arenas such as Cyber Laws, Corporate Laws, Intellectual Property Rights, etc.


"The water supply of more than 2 million Californians has been exposed to harmful levels of nitrates over the past 15 years -- a time marked by lax regulatory efforts to contain the colorless and odorless contaminant, a California Watch investigation has found.
Nitrates are now the most common groundwater contaminant in California and across the country.
A byproduct of nitrogen-based farm fertilizer, animal manure, wastewater treatment plants and leaky septic tanks, nitrates leach into the ground and can be expensive to extract.
The problem affects both rural Californians and wealthier big-city water systems. State law requires public water systems to remove nitrates. Many rural communities, however, don't have access to the kind of treatment systems available in metropolitan areas.
Nitrates have been linked to 'blue baby syndrome,' which cuts off an infant's oxygen supply. Some studies have found connections to certain cancers in lab animals."

This is a common skin disease in children.
It is so common that people have given it a few names:
- Eczema (name most people use)
- Atopic (a-top-ic) eczema
- Atopic dermatitis
To avoid confusion, we’ll use the medical term atopic dermatitis.
Children often get atopic dermatitis (AD) during their first year of life. If a child gets AD during this time, dry and scaly patches appear on the skin. These patches often appear on the scalp, forehead, and face. These patches are very common on the cheeks.
No matter where it appears, AD is often very itchy. Infants may rub their skin against bedding or carpeting to relieve the itch.
In children of all ages, the itch can be so intense that a child cannot sleep. Scratching can lead to skin infection.
Because atopic dermatitis can be long-lasting, it is important to learn how to take care of the skin. Treatment and good skin care can alleviate much of the discomfort.

Professor Jane Harding
Professor Jane Harding's research investigates how events and interventions during pregnancy, birth and the newborn period affect the health of mothers and babies.
Professor Jane Harding, is a neonatologist (Paediatrician who specialises in the care of newborn babies) and undertakes research with a multidisciplinary team of students, clinicians, scientists and support staff.
They are investigating how events and interventions during pregnancy, birth and the newborn period affect mothers’ health and babies’ growth, development, and long term health. Currently, one of her main areas of research is about blood sugar levels in newborn babies.
Her team have conducted a world-first trial where they showed that dextrose gel massaged into the inside of a baby’s cheek can be used to treat hypoglycemia (low blood sugar levels), reducing the need for admission to intensive care for treatment on a drip. This has led to studying whether dextrose gel can be used to prevent hypoglycaemia in babies who are at risk, as well as studying the later outcomes of these babies, to determine at what levels hypoglycaemia should be treated to avoid brain injury, and if these interventions provide any significant benefits for later in childhood growth, development and educational achievement.

FAIRBANKS, Alaska - It's time once again for our Garden Report with Julie Riley from the Cooperative Extension Service. Tonight Julie will give you tips on how to plant beets for the upcoming summer.
It's time to finish up planting and this year I'd like you to give beets a chance. If you think that beets taste like Earth, you're right! Beets produce a substance called geosmin. Geosmin is also produced by a cell living bacteria that gives that characteristic earthy smell when you first turn over the soil in the spring.
So if this earthiness is something that you like, there are a couple of varieties that have more geosmin than others.
The candy striped giada and the other variety "Bulls Blood". You get these locally at the seed racks.
Now, there's one critical piece of information that gardeners tend to overlook, and that is each beet seed is actually a cluster of more than one seed.
Sometimes it is difficult to tell that more than one plant has come up. So, one of these you are gently going to pull them apart, and one of these has got to go.
So this summer give beets a chance. You've got until the first part of July to put beets in the ground. Fill in any of those bare spots where you have harvested your arugula or radishes.
I'm Julie Riley, join me next week for Garden Report when we talk about lilacs.

- It is caused by viruses known as rhinoviruses
- The rhinovirus is a microscopic organism which invades the mucus cells of the nose.
- As viruses are essentially genetic, this entails that they can also mutate.
- There are now about 250 known rhinoviruses in the community, which means that there are about 250 colds flying around out there for you to catch.
What are the current treatments?
- From the early warning of the wet runny nose phase, immediate isolation must be sought.
All you can do is stock up on medicines that will only alleviate the symptoms caused by the irrevocable army of viral invasion.
Frequent hand washing is also an essential part of combating the contracting of cold viruses.

Avaz FreeSpeech is a visually appealing and interactive app that guides its users to create grammatically correct sentences. FreeSpeech helps anyone with a language impairment practice and develop grammar skills. Drag and rearrange picture tiles, and FreeSpeech will convert them into a perfectly grammatical English sentence. Explore how tenses, sentence forms, parts of speech, and other grammatical properties change the structure of English — and it’s all visual!
FreeSpeech is the perfect app for introducing a child to the complexities of English grammar, working with kids with language/speech/hearing impairments or individuals learning English from a second language.
FreeSpeech is unique because it’s the only app in the world that predicts grammar. You can throw a bunch of picture tiles at it, and the app will automatically figure out a grammatically correct sentence from them.
It is possible to manipulate words, tenses and structure as if you were manipulating building blocks. You can even use a Spanish interface, so you throw Spanish words at it and it creates perfect English sentences.
The app lets teachers and learners model/recast/contrast various grammar rules pictorially, all the while speaking out correct English.
While working with kids who have trouble speaking, App Developer Ajit Narayanan sketched out a way to think about language in pictures, to relate words and concepts in “maps.” The idea now powers the FreeSpeech app, which can help nonverbal people communicate. Check out Ajit’s TED Talk.

Microsoft Research showed off some fascinating new technology concepts with three demo videos, two of which heavily integrate Kinect sensors. The projects include a 3D desktop concept, the IllumiShare remote sharing system, and the Holoflector augmented reality mirror, all of which can find diverse applications in gaming, education, and business.
The Kinect-integated 3D desktop involves a transparent display that folds up so that your hands lie on a keyboard behind the screen. Objects and graphics on the screen appear in a virtual 3-dimensional space in which your hands can virtually manipulate them from behind the screen. The system also tracks eye movement so that 3D objects appear correctly on the screen.
The IllumiShare is a virtual workspace system that looks like a simple desk lamp. It actually consists of both a camera and projector to simultaneously capture and project video. The challenge is for it to be able to differentiate between that which it has projected versus that which is physically present so that it does not re-project visuals in an infinite loop. The IllumiShare has many educational applications and it's best to see it in action for yourself in the video below.
The Holoflector features a transparent mirror that sits in front of an LCD screen so that users can see both their reflections as well as any virtual elements displayed on the screen behind the mirror. Using Kinect's sensors and motion capture capabilities, virtual reality elements can be combined with physical reality for a blended visual on the mirror.

HONOLULU — Before Apollo astronauts went to the moon, they went to Hawaii to train on the Big Island’s lunar landscapes.
Now, decades-old photos are surfacing of astronauts scooping up Hawaii’s soil and riding across volcanic fields in a “moon buggy” vehicle.
The Pacific International Space Center for Exploration Systems, a Hawaii state agency, is displaying the photos at its Hilo headquarters. Rob Kelso, the agency’s executive director, found the images at the Johnson Space Center in Houston.
Astronauts from Apollo missions 13 through 17 trained in Hawaii as did some back up crews, Kelso said.
Some training was on Mauna Kea volcano, where glacial runoff crushed and refined rock into power. Astronauts also trained on recent lava flows.
Today, robots are tested on the Big Island for moon and Mars missions.
In recent years, engineers have tested technology to pull oxygen out of the island’s dirt, which is volcanic basalt like the Martian and lunar soil. Future missions could use this technology to extract oxygen from the land instead of taking it along. The oxygen could be used for breathing, to make fuel or for other purposes.
Kelso said scientists are also interested in testing robots at the Big Island’s lava tubes and lava tube skylight holes, which resemble similar formations recently spotted in high-definition images taken by satellites orbiting the moon, Mercury, Venus and Mars.
Lava tubes are tunnels made when lava forms a solid roof after flowing steadily in a confined area for hours. Skylight holes are formed when part of the tube breaks.


LEAD EXPOSURE, CRIME SEEM TO CORRELATE
October 30, 2007
For decades, researchers have known that lead poisoning lowers children's IQs and puts them at risk for severe learning disabilities and more impulsive, sometimes violent behavior. New research increasingly suggests that lead also affects long-term juvenile and adult crime rates, says USA Today.
Among the most startling findings:
- A pair of studies by economist Rick Nevin suggests the nation's violent-crime rate in the second half of the 20th century is closely tied to the widespread consumption of leaded gasoline.
- According to Nevin, the trend lines match almost perfectly -- Leaded-gas use climbed in the 1940s and fell in the early 1970s; 23 years later, rates for violent crime followed in near unison.
- Its gradual demise in the 1970s, he says, did more to stop violent crime among people who came of age in its wake than any social policy.
But Richard Rosenfeld, a criminologist at the University of Missouri-St. Louis, says there are many more factors to consider -- economic trends, incarceration policies and policing strategies, among others -- before researchers can tie long-term violence levels and lead so closely.
"There is probably a real correlation, but we simply don't know if there is a real causal connection," says Rosenfeld.

March 28 : Otago University scientists say that eating two Brazil nuts everyday may help reduce the risk of a wide range of conditions, including cancer and heart disease.
Professor Christine Thomson says that Brazil nuts may provide such beneficial health effects by helping maintain the levels of selenium, a trace mineral essential for producing antioxidant enzymes and other proteins that protect cells from damage.
The researcher, who led the first ever research into how much of the essential micronutrient people can obtain from Brazil nuts, pointed out that people in New Zealand generally had “marginal” selenium levels because the soil was deficient in selenium.
“There is mounting evidence that a marginal selenium status can lead to an increased risk for a range of conditions, including cancer and cardiovascular disease,” stuff.co.nz quoted her as saying.
During the study, described in the American Clinical Journal of Nutrition, 60 volunteers were divided into three groups â€” one ate two Brazil nuts a day, one received a 100 microgram selenium supplement, and one was given a placebo.
After 12 weeks, the researchers observed a 64.2 per cent increase in the blood selenium concentrations among participants who ate Brazil nuts, compared with 61 per cent in the selenium supplement group.
Upon measuring the activity levels of a key antioxidant, the researchers noted that the Brazil nut eaters’ levels went up by 13.2 per cent, compared with 5.3 per cent in the supplement group.
The study report says that research is underway to investigate the link between low selenium levels and higher rates of cancer and heart disease.
“Kiwi farmers have been feeding selenium supplements to their cattle for years … but it’s only in the past few years that people have cottoned on to the fact it might be good for them too,” Wellington Nut Store co-owner David Upchurch said. (ANI)

Globular cluster NGC 362. Globular clusters are spherical groups of very old stars that are tightly bound by gravity and orbit a dense central core. They can contain over a million stars within a volume only a few hundred light years across. They formed billions of years ago, and are distributed in halos around many galaxies, including the Milky Way. NGC 288 is around 27,700 light years from Earth, in the constellation of Tucana.

The world’s oldest petroglyphs have been found in Nevada, and scientists say the discovery has changed much of what we believed about early humans.
The oldest petroglyphs range between 10,000 and 15,000 years old, and we don’t know exactly how old the etchings discovered on limestone boulders near Pyramid Lake in northern Nevada are precisely.
Previously discovered petroglyphs were discovered in a similar dry lake bed in Oregon, and dated to be 7,600 years old. But Eugene Hattori, the curator of anthropology at the Nevada State Museum in Carson City, co-authored a paper on the oldest petroglyphs and says that the Nevada set is older — and illuminating:
“We initially thought people 12,000 or 10,000 years ago were primitive, but their artistic expressions and technological expertise associated with these paints a much different picture.”
Radiocarbon testing was used to date the oldest petroglyphs, and lead author Larry Benson says:
“Whether they turn out to be as old as 14,800 years ago or as recent as 10,500 years ago, they are still the oldest petroglyphs that have been dated in North America.”
Dennis Jenkins, a University of Oregon Museum of Natural and Cultural History archaeologist, said the oldest petroglyphs haven’t conclusively been linked to any ancient peoples:
“When you get back into this time period, if you speak with Native Americans they will tell you they were made there and that is obviously their people and their artwork. But approaching it from a scientific point of view — what we can prove — at this point, it is impossible to connect these to any tribal group.”
The oldest petroglyphs are described as less pictorial, and more geometric patterns.

As mentioned previously, a barrel of crude oil has a mixture of all sorts of hydrocarbons in it. Oil refining separates everything into useful substances. Chemists use the following steps:
- The oldest and most common way to separate things into various components (called fractions), is to do it using the differences in boiling temperature. This process is called fractional distillation. You basically heat crude oil up, let it vaporize and then condense the vapor.
- Newer techniques use Chemical processing on some of the fractions to make others, in a process called conversion. Chemical processing, for example, can break longer chains into shorter ones. This allows a refinery to turn diesel fuel into gasoline depending on the demand for gasoline.
- Refineries must treat the fractions to remove impurities.
- Refineries combine the various fractions (processed, unprocessed) into mixtures to make desired products. For example, different mixtures of chains can create gasolines with different octane ratings.
The products are stored on-site until they can be delivered to various markets such as gas stations, airports and chemical plants. In addition to making the oil-based products, refineries must also treat the wastes involved in the processes to minimize air and water pollution.


The Basilica of Maxentius or the Basilica of Constantine (begun by Maxentius, but finished by Constantine; hence, the two names) was the last non-Christian basilica built on the Roman forum. It was built for commercial and administrative purposes. Parts of the Velia ridge between the Esquiline and the Palatine hills had to be leveled for the basilica.
The Basilica of Maxentius was built with arches of both the barrel and groined variety, but only three of the barrel vaults remain standing. The rectangle that formed the basilica was 100×65 m, which was divided into a central nave (80×25 m) and aisles to either side. Three groined vaults (=where 2 barrel vaults intersect at right angles) covered the nave, with a maximum height of 35 m. Eight Corinthian columns 14.5 m high supported them. There may have been large windows on the upper walls of the nave (referred to as the "clerestory" or "clearstory"). Floors were marble, like the Pantheon, and the roof was covered with gilded bronze tiles.

Raoult’s law gives a method of estimating the composition and pressure of the vapour above a liquid mixture. This article describes the basis of Raoult’s law and provides an example of how to apply it.
Due to their large capital expense, pipelines are often utilized for the transfer of multiple products. During operation of these multi-product pipelines, the interface between two adjacent products extends (referred to as interface mixing), resulting in the contamination of each product. This interface is typically sent to slops collection for reprocessing or disposal at additional cost to the operator. Therefore the economics of a pipeline can often be improved through a study of product interfaces under various operational conditions to aide in the minimization of interface mixing. This article presents several empirical methods by which interface mixing can be quantified.
For some engineering calculations, particularly in hydrocarbon processing, it is necessary to estimate the viscosity of a mixture (blend) of two or more components. This article presents the Gambill and Refutas methods, which are commonly used in petroleum refining for predicting the viscosity of oil blends.


Schools lose things all the time. Textbooks. Laptops. Students.
Now — thanks to Secure RF, a Westport company — administrators can track anything they want. Gone are the days when valuable resources walk out the door — including kids and teachers.
According to BrickhouseSecurity.com, a blog covering all things surveillance, Secure RF will use a $100,000 National Science Foundation grant to test radio frequency identification (RFID) tags — aka chips.
Embedded in a laptop — or student ID or backpack — RFID scans a room “to figure out what’s there and what’s missing.”
The technology allows school administrators to “take a quick count of who is in class and who’s not, who walked out the front door, or who walked into the library.”
And guess which school system is thinking of testing the concept?
Gotcha! Not Westport.
Currently, the program is limited to volunteer students and parents.
As expected, not everyone is leaping onto the RFID bandwagon.
A school board member said: “I can perceive parents would have an issue with tracking kids through the school and through town.”
BrickhouseSecurity.com noted, “if the chip is in an ID card or backpack, high school students could easily ditch these items, rendering the system somewhat ineffective… It seems like this program is primarily targeting younger children and assets.”
High-tech efficiency — or Big Brother run wild? Whatever the answer, Fairfield County is involved in both the problem and its solution.


The Papua New Guinea banking system is made up of the Central Bank of Papua New Guinea (BPNG), four commercial banks and several licensed financial institutions and credit unions (or savings and loan societies).
The key financial institutions are supported by overseas-related companies and associates.
The merger of the former Papua New Guinea Banking Corporation with the Bank South Pacific Limited in 2002 makes the Bank South Pacific Limited the largest bank in PNG.
The National Development Bank is another locally owned bank which was enacted by Parliament on 25 April 2007.
These are the only locally owned banks while the other three commercial banks, namely Westpac (PNG) Limited, ANZ (PNG) Limited and Maybank (PNG) Limited, are subsidiaries of international banks.
While most financial services are available, their supply is limited. Overseas investors may not be able to secure substantial funds locally. New operations would normally need to bring funds from overseas to establish projects.


Spain in the Middle Ages was home to scholars of great renown such as Abraham ibn Ezra (1089 - c. 1164), Judah ha-Levi (1086-1145), Rabbi Moses ben Maimon (Maimonides/Rambam 1135-1204) and Rabbi Moshe ben Nachman (Nachmanides/Ramban - 1194-1270). By the middle of the 13th century, however, the welcoming attitude of the Spanish kingdoms that had allowed Jewish life to thrive, had vanished.
Rabbi Jacob ben Asher was born in Germany in 1269 C.E. When he was still a child, however, his family was forced to leave Germany, and they settled in Toledo, Spain. Rabbi Jacob’s father, Rabbi Asher ben Jehiel (aka the ROSH), was asked to become the Chief Rabbi, even though he followed Ashkenazi, not Sephardi, customs. This unique blend of Ashkenazi heritage and style of Talmud study in combination with living in a Sephardi community led to Rabbi Jacob ben Asher’s incredible contribution to Jewish scholarship, Arba'ah Turim (Four Rows).
The Arba'ah Turim, like the Rambam’s Mishna Torah*, was a codification of Jewish law intended to make it easier for Jews to fully observe the law. Rabbi Jacob divided all of Jewish law into four sections: Orach Chaim (Way of Life) covers basic Jewish life and ritual, Yoreh Deah (Teacher of Knowledge) deals with dietary laws, mourning and a number of other aspects of Jewish life, Even Ha’ezer (Stone of Help) contains laws relating to marriage and family, and Choshen Mishpat (Breastplate of Judgment) discusses civil and criminal law.
What was most unique about the Arbaah Turim was that Rabbi Jacob (who was also known as Ba’al Ha’turim - Master of the Rows) cited the legal traditions of both Sephardi and Askenazi rabbis. His work became the basis for the ultimate codification of Jewish law, the *Shulchan Arukh (Composed by Rabbi Joseph Caro in the 1560s).
Rabbi Jacob died on 12 Tammuz, 1340.

Messier 69 (also known as M69 or NGC 6637) is a w:globular cluster in the w:constellation Sagittarius. It was discovered by w:Charles Messier in August 31, w:1780, the same night he discovered M70. At the time, he was searching for an object described by LaCaille in 1751-2 and thought he had rediscovered it, but it is unclear if LaCaille actually described M69.
M69 is at a distance of about 29,700 w:light-years away from w:Earth and has a spatial radius of 42 light-years. It is a close neighbor of w:Globular Cluster M70, 1,800 light-years separating the two objects, and both these clusters lie close to the Galactic Center. It is one of the most metal-rich globular cluster known.


I elaborate on the idea of using man-made climate change to fight climate change, whether man-made or not.
Climate engineering, or what I call Operation Sunscreen, would mean trying to alter the heat absorption properties of the atmosphere. The goal might be to reduce average temperatures by, say, 2 degrees centigrade.
I have no idea how to reduce heat absorption, but one can imagine a number of possible approaches to climate engineering: putting reflectors out into space; using some physical or chemical process to "wash" carbon out of the atmosphere; or coming up with a way to reduce concentrations of water vapor (the most abundant greenhouse gas) in the atmosphere.
... it would be rather a shame to toss away $400 billion dollars a year using the de-industrialization strategy and then discover "Oops, the cause of global warming wasn't carbon-dioxide emissions after all. It must have been something else, because temperatures are still rising, even though we reduced emissions to levels that we thought would stabilize global temperature." Instead, climate engineering could reduce global average temperature regardless of whether global warming is caused by carbon-dioxide emissions or not.
UPDATE: Astronomer Roger Angel thinks that the reflector idea could work.
"The concept builds on existing technologies," Angel said. "It seems feasible that it could be developed and deployed in about 25 years at a cost of a few trillion dollars. With care, the solar shade should last about 50 years. So the average cost is about $100 billion a year, or about two-tenths of one percent of the global domestic product."

ESA - Mars Express Mission patch.
Jan. 23, 2017
Frost build-up near Mars north pole
This animated gif shows the build up of frosts in a 73 x 41 km section of the north polar ice cap of Mars between November and December 2004.
The images were taken by the High Resolution Stereo Camera on ESA’s Mars Express during its first year at the Red Planet. It has been orbiting Mars for over 13 years.
The first image was taken on 23 November 2004 during orbit 1087, and the second of the same area on 30 December 2004, during orbit 1219. The images are centred at 79.94ºN / 44.11ºE. The interleaving frames in the gif are interpolated to give a smooth appearance.
The north polar icecap comprises layers of water-ice that extend to a depth of around 2 km. The layers result from seasonal melting and deposition of ice mixed with dust.
During winter the water-ice is covered by a thin layer of carbon dioxide ice that is a few centimetres to around a metre thick.
During the warmer summer months, most of the carbon dioxide ice turns directly into vapour and escapes into the atmosphere, leaving behind the water-ice layers.
But when the seasons start to change again, a thin veneer of solid carbon dioxide begins to encroach, as seen in these images, which captures subtle changes between summer and autumn.
The original images are available in the Mars Express archive, and are shown at 50 m/pixel.

The carotid arteries, located on either side of the neck, provide important blood flow to the brain. As people age, plaque can build up on the walls of the body’s arteries, causing the arteries to narrow and stiffen (known as atherosclerosis). When this process can occur in the carotid arteries (termed carotid stenosis) and is a significant risk factor for stroke. Carotid stenosis due to atherosclerosis is one of the most common causes of strokes and stroke-like symptoms.
Carotid stenosis can be treated by carotid endarterectomy – a procedure to remove plaque build-up from a carotid artery and help prevent stroke – is considered the standard treatment for people with carotid stenosis. Carotid endarterectomy is performed through a small incision in the neck, and most patients return home from the hospital the day after the procedure.


1. LEGO perimeter and area
Elijah needs more practice with perimeter and area. I saw this idea on Pinterest, and I knew it would be perfect for him.
I grabbed various building plates.
And gave them each a number ~
Then I gave Elijah some printable pages to work through.
I love when LEGO makes all the difference.
2. Bird Nesting Materials
We talked about spring and birds and nests. We cut up a bunch of yarn (my stash was getting kind of CRAZY), and stuffed it in a suet feeder. Now the birds can come pluck a piece. We have lots of nests on our property, and we are hopeful that we'll see some of our colored yarn in some new nests!
Yet another idea from Pinterest!

Niektoré aspekty pomenovania etnických a národnostných menšín
Some aspects of the term of ethnic and national minorities
The ethnic and the nation frontiers usually are not identical with the state borders. There is misgiving quite often, that the request for the change of borders based on ethnic principle be presented. Because of that, the state politics puts stress on differences between minority and the root nation and leads to different minority denomination. As an example of this situation can serve the efforts to separate the Ugrian Ruthenians from the rest of Ruthenians and to give them different denomination such as Ugrorussians, Carpathorussians etc. That caused dividing one minority group into several ones with different conciouseness. The effort to unite the ethnic leads its members also to searching for uniting denomination, which would be acceptable for the majority involved even though it would not truly describe objective reality. The question of ethnical or national minorities is very complicated. Those who should govern and decide answering the question should be primarily minority members. But it is necessary to provide suitable conditions for their activities, which would guarantee a free and democratic decision-making based on objective information available. This information is needed not only for the members of minority, but also for majority nation so that it can understand minority's needs or requirements and support their fulfilling.
Ethnic minoritues. National minorities. Ugrian Ruthenians. Carpathorussians.

Corruption is one of the greast problems problems facing developing the countries all over the world. From a human rights
perspective, corruption is one of the greatest obstacles in fulfilling a state's obligation to protect and promote human
rights. Corrupt political systems deny the fundamental right to democratic participation. Corrupt judicial systems not only
violate the basic right to equality before the law but deny procedural rights guaranteed by international hr
conventions. Corruption in public administration endangers the right to life, as when it causes funds to be diverted from
medical care to private pockets or when it allows for the manufacture of defective and dangerous products or buildings.
Generalized corruption, specially at the higher levels, rob a people of their wealth and leads to grave violations to
economic rights, it destroyes economies and condemns peoples to unemployment and hunger. It also leads to social unrest,
which can sometimes turn violent.


The Great Tom Fuller
A great historian and public intellectual, Thomas Fuller championed moderation and responsibility in a time of war, polarisation and misinformation.
Samuel Taylor Coleridge once said that two writers above all others excited in him ‘the sense and emotion of the marvellous’. One was William Shakespeare and the other was a 17th-century historian called Thomas Fuller. ‘The Great Tom Fuller’, as Samuel Pepys called him, blazed like a comet in his lifetime and glowed for a good while afterwards, but then seemed to drop almost entirely out of the firmament. He is worth remembering today not only for the warmth of his voice and the strength of his intellect, but as a reminder of the power of history in times of extreme violence.


Effects of social rearing conditions on conditioned suppression in rats
Languages of publication
Twenty-two rats were reared in standard conditions during the first two months of their life. Then the animals were divided into two groups exposed to different rearing conditions. Twelve animals (Group SO) were housed socially, six animals per cage, and for three weeks they were subjected to sensory stimulation in an enriched environment. The other ten subjects were kept individually (Group IN); one rat per mesh cage, in conditions of relatively impoverished sensory stimulation. In both groups the training of the conditioned emotional response (CER) was performed when animals were three months old. In contrast to IN subjects, the rats subjected to permanent social contacts and reared in the enriched environment (Group SO) revealed almost equally low instrumental response rates in trials with the conditioned stimulus (CS) paired with nociceptive foot-shock (US), and in periods when no CS and/or US were applied. The results suggested that early exposure to an enriched environment caused a later decrease of the animals? capability to differentiate between the aversive CS and cues of the experimental context. This cognitive impairment was probably a secondary effect of fear generalized to the entire experimental situation.

Ohio County is south of Dearborn County, just across the north-to-south flowing Ohio River from Kentucky.
It is Indiana’s smallest county in population (6,128) and size (86 square miles).
It was named for the Ohio River, and is one of three Ohio counties; the others are in Kentucky and West Virginia.

The recent discovery of contaminating porcine circovirus 1 DNA in Rotarix underscores the power of deep sequencing to ensure the purity of viral vaccines. The price of deep sequencing is now low enough that it is possible to use this technology to examine not just viral vaccines, but any biological product produced in mammalian cells for the presence of adventitious agents.
Some individuals have told me they do not want to know what is in their vaccines. Their logic is that even if we do identify a contaminating virus, we might not know if it is of any consequence to human health. But we would nonetheless worry about its presence and unnecessarily spend millions of dollars to remove it. The contrary view is that, although infection with porcine circovirus 1 might be benign, who can be confident that in 20 years the infection will not lead to dire consequences?
I am interested in what readers of virology blog think about this issue. Let your view be known by taking the poll below.

William Bradford (1590–1656) religious leader and colonizer
Bradford was born in Austerfield, Yorkshire, into a yeoman farming family. He joined a separatist congregation as a young man and in 1608 followed John Robinson to Leyden, Holland, to avoid religious persecution by King James I. Though granted complete freedom of conscience there, the separatists feared that their families were losing their English identity and began searching for a new home. In 1617, Bradford served on a committee to arrange migration to America and in 1620 was one of 102 Pilgrims to set sail for the New World aboard the Mayflower, an expedition funded by an English joint-stock company with only nominal interest in the Pilgrims’ religious cause. Bound with a royal patent to settle in Virginia, the Pilgrims had no legal standing in New England, where they landed as the result of a navigational error. This led Bradford and the other men in the group to sign the Mayflower Compact (November 11), establishing “a civil body politick” to protect the colony from anarchy.
After the 1621 death of John Carver, the colony’s first governor, Bradford was elected to the position. As leader of a small band of poor settlers, he faced many difficulties. In 1623, he abandoned Pilgrim communalism as detrimental to initiative; in 1636, he encouraged the codification of local laws and a basic statement of rights. Bradford led the Pilgrims to honor their financial commitments, though it took more than 20 years to repay their English investors. Much of Plymouth’s success owed to Bradford’s religious tolerance and good relations with the native peoples of the region. His historical masterpiece, Of Plimmoth Plantation, is one of the most vivid accounts of early settlement in America. It was written between 1630 and 1650, but not published in full until 1856.


I went looking through the chemicals the other day, and I decided that it had been too long since I recorded a good chemical demonstration video.
So I pulled out some sodium peroxide, Na2O2. The MSDS sheet looks interesting:
DANGER! CORROSIVE. STRONG OXIDIZER. CONTACT WITH OTHER MATERIAL MAY CAUSE FIRE. CAUSES SEVERE BURNS TO EVERY AREA OF CONTACT. HARMFUL IF SWALLOWED OR INHALED.
Contact with combustible, organic, or oxidizable substances may cause extremely violent combustion. May react explosively in contact with large amounts of water.
it’s a strong oxidizer, plus it reacts with water? If there were ever a substance tailor-made for a cool reaction demonstration, sodium peroxide would have to be it. So let’s see … what would happen if you took some sodium peroxide, sprinkled it on top of a few combustible cotton balls, and then added water?
No, really. I’ve found this demonstration mentioned in several of my chemistry books. (Ever notice how the more impressive chemical demonstrations involve doing things the MSDS specifically warns against?)
The idea behind this particular demonstration is that the reaction of sodium peroxide with water will release hydrogen peroxide and quite a bit of heat.
Na2O2 + 2H2O –> 2NaOH + H2O2 … and lots of heat.
Under these conditions hydrogen peroxide also decomposes, releasing oxygen – which will speed up any combustion that happens to be occurring.
2H2O2 -> 2H2O+O2
In short, we get oxygen and a lot of heat. This usually makes for a fun demonstration. Take a look.
Looking a little more closely, you can see that after only a few seconds, the cotton catches fire.
And after several seconds more, the evaporating dish just can’t handle any more.
… and this is why we always wear safety glasses when doing chemical demonstrations. But perhaps I should have given the camera some safety glasses, too?


A bird’s-eye view of the Geopark project
GAIA · The Big Mother is a 48′ documentary about the origin, evolution and future of the Earth, focusing on the geological concepts and the role of life and humans. Facts and ideas are shown through illustrations and animations together with films made on places like museums and relevant landscapes.

La Gran Aventura Canadenca: A hundred years ago, the creation of the company Barcelona Traction, Light and Power, better known as “La Canadenca”, was the beginning of big changes in Catalonia. A North American engineer , Fred Stark Pearson, set up the company in Toronto and built the first hydroelectric plants in the Pyrenees, the biggest plants that had ever been built in Europe. In a few years, electric power arrived at the main cities and factories.
“La gran aventura de La Canadenca” ( The great Adventure of La Canadenca) collects the story of people that lived at first hand the adventure that brought electricity from the mountains until factories and cities. Through the experience of four people, the documentary explains in a realistic and epic way the two decades, from the first steps of la Canadenca until the International Exhibition in Barcelona in 1929.

Serrapeptase is a is a proteolytic enzyme, meaning it breaks down proteins into smaller components called amino acids. It’s produced by bacteria in the digestive tract of silkworms and allows the emerging moth to digest and dissolve its cocoon; and it helps the whole body breakdown protein, acting like a scavenger.
Preliminary evidence suggests is active systemically and may support a healthy inflammation response. Preliminary evidence also suggests that when taken orally, this enzyme may reduce the viscosity of mucus in the respiratory tract. Serrapeptase is provided as a delayed release vegetarian capsule, designed to provide the most benefit.

Forensic experts describe finding human remains with “knotted loops of rope binding their wrists together behind their backs”
Somalilandsun – When heavy rains in 1997 exposed bones, ropes, broken skulls and torn pieces of clothing in shallow graves in Hargeysa, capital of the Republic of Somaliland, northwestern Somalia, it set in motion the rudimentary beginnings of an international investigation into alleged war crimes.
At the request of an independent expert of the UN Commission on Human Rights, an international forensic team, provided by Physicians for Human Rights (PHR), came to Somaliland in December 1997. Two North American forensic experts were shown more than 100 alleged mass-grave sites. After preliminary investigations, the team reported that some of the sites did indeed exhibit characteristics of mass graves and contained evidence of gross human rights abuses. It recommended that the sites be preserved, and an international team of forensic specialists be authorised by the UN to carry out further investigations.


A cataract is a cloudy or opaque area in the lens of the eye. Cataracts usually develop as a person gets older and may run in families. Other environmental factors such as smoking or exposure to toxic substances can also accelerate the development of a cataract. Cataracts can cause visual problems such as difficulty seeing at night, seeing halos around lights, and sensitivity to glare.

Measuring Contraceptive Failure
One of the most vexing problems for practitioners and policymakers concerned with family planning, not to mention for women and men trying to make the best choices for their reproductive lives, is contraceptive failure—the occurrence of pregnancy among couples who are trying not to conceive. Decades of research, employing increasingly sophisticated statistical techniques, have documented the incidence of contraceptive failure, with the aim of learning how to bring down levels of unintended pregnancy. Back in 1973, an analysis of data from the 1970 National Fertility Study was one of the first efforts to examine failure and how it differed by contraceptive method and among subgroups of ever-married women. In 1982, the National Survey of Family Growth (NSFG) had become the go-to data source, and researchers applied new multivariate techniques to more fully understand disparities, but only among married women. Fast-forward to 2017: The NSFG is still the go-to source, data are adjusted for abortion underreporting, women are included regardless of their marital status, and failure is measured not only by method, but also by duration of use.
The good news in the most recent report, reflecting the experiences of 2006–2010 survey respondents, is that failure rates associated with most reversible methods have been declining; some are at all-time lows for the U.S. Not only that, but the overall failure rate for reversible methods is approaching the goal set in the federal government’s Healthy People initiative. Still, differences by method and among demographic subgroups suggest the continuing importance of efforts to ensure that U.S. women and men have access to a full range of contraceptives and receive the information they need to use them effectively.


Few public policy issues generate more heated debate than the issue of affirmative action. While a 2021 Gallup poll showed a growing trend of Americans supporting affirmative action for racial minorities, a 2022 Pew Research Center report found evidence that public support for affirmative action is ailing across all racial groups. These discrepant poll results underscore the complexity of attitudes about affirmative action and begs the question: Has affirmative action outlived its usefulness?
This question is being addressed as the Supreme Court deliberates over the arguments from two lawsuits against the University of North Carolina and Harvard University.
Based on questioning from the court’s conservative majority during the oral arguments, the Supreme Court is skeptical about race-conscious college admissions and is likely to ban affirmative action. For example, Supreme Court Justice Clarence Thomas pressed the university's lawyers to explain the educational benefits of diversity.
In addition to moral and legal arguments against affirmative action, Thomas’s concerns are essentially psychological in nature. Thomas has argued that affirmative action is benign discrimination that teaches racial minorities they cannot compete without help and stamps racial minorities with a badge of inferiority.
. . .
If affirmative action was so psychologically damaging to racial minorities, one would expect the trauma and stress of constantly feeling inferior to be so debilitating that it would result in a majority of these students dropping out of school. This is not supported by data.

An early to middle Bronze Age barrow excavated in South Wales.
Excavation of the barrow revealed two phases of use with the ditch being cleaned out. A number of cremation burials were discovered within the central area of the barrow, two of which were contained in urns.
The barrow was located within an area of other ceremonial monuments and features.


That the Hopi Indians are the most primitive people and their almost inaccessible homes the most primitive to be found in the United States is conceded by all travelers. The snake dance, which takes place in August, is a pagan ceremony giving thanks for rain and bounteous harvests. The Venomous snakes, even rattlers, are in no way treated to make them harmless. the Indians have an antidote for snake poison which no white man may know. the dancers are often bitten by rattlesnakes without fatal results.


When George Washington was a young man, he copied out a list of 110 “Rules of Civility and Decent Behavior in Company and Conversation.” Some of the rules in his list dealt with the niceties of going to a dinner party or meeting somebody on the street.Read the rest here.
“Lean not upon anyone,” was one of the rules. “Read no letter, books or papers in company,” was another. “If any one come to speak to you while you are sitting, stand up,” was a third.
But, as the biographer Richard Brookhiser has noted, these rules, which Washington derived from a 16th-century guidebook, were not just etiquette tips. They were designed to improve inner morals by shaping the outward man. Washington took them very seriously. He worked hard to follow them. Throughout his life, he remained acutely conscious of his own rectitude.
In so doing, he turned himself into a new kind of hero. He wasn’t primarily a military hero or a political hero. As the historian Gordon Wood has written, “Washington became a great man and was acclaimed as a classical hero because of the way he conducted himself during times of temptation. It was his moral character that set him off from other men.”
Washington absorbed, and later came to personify what you might call the dignity code. The code was based on the same premise as the nation’s Constitution — that human beings are flawed creatures who live in constant peril of falling into disasters caused by their own passions. Artificial systems have to be created to balance and restrain their desires.
The dignity code commanded its followers to be disinterested — to endeavor to put national interests above personal interests. It commanded its followers to be reticent — to never degrade intimate emotions by parading them in public. It also commanded its followers to be dispassionate — to distrust rashness, zealotry, fury and political enthusiasm.


The Sound Of Music..
The Sound Of Music..1 min 111 1 min 111
It's the sense and our feeling,
Which always lets us speak something.
The sense is active but silent,
But its actions are very vibrant.
The sense sometimes seems to fail due to emotion,
It can be visualized through our actions.
Sometimes we speak and others say it nonsense,
Because their sensitive mind remains absent.
The sense drives us to act and react,
It understands and realize the real fact.
This develops our feelings,
Which make us alert while watching.
These sense and feelings get us influenced,
When The Sound Of Music we heard.
The Sound Of Music controls many things,
Which include the emotions out of sense and our feelings.
The sense got attracted to The Sound Of Music,
It just works like magic.
The Sound Of Music touches our feelings,
It develops different emotions of human beings.
The feeling to dance with The Sound Of Music,
Activate our senses and it's automatic.
Sometimes The Sound Of Music makes us sing,
It brings our emotions with sense like anything.
The Sound Of Music differ as we hear,
Because it's a creation and rare.
We sometimes get attached to The Sound Of Music,
Because it controls our sense and feeling like magic.
The Sound Of Music matches the rhythm of nature,
Which gives us utmost pleasure, when we hear.
Let us restore the rhythm of this unique creation,
The Sound Of Music always plays with our emotion.


Winter is coming to an end, at least in astronomical terms. Officially we are halfway to spring, which means you should start to notice a little more daylight as we gain minutes each day. Also, imagine a planet orbiting two stars, also known as a binary star system. There are three such systems identified in our galaxy where a planet is orbiting two stars and treating those two stars as a single gravitational body. A well known binary star is Algol, also known as the Demon star, which can be seen with the naked eye in the right conditions. There are many other binary stars not too far away like Alpha Centauri at four light years away. And don’t miss what’s in the night sky this week including a full moon. All this and more on this week’s Sky Talk.

Helping to develop your student's phonological awareness is an important skill required to be a reader. When our students sound out words, they slowly say each sound in a word (c-a-t), and then say the sounds quickly together to "read" the word (cat). This ability to blend ( combine the sounds), and segment (isolate sounds) are skills that are so important when learning to read. This video offers an opportunity for children do both. You can use the video with or without sound. The best part you can have the children use this in a whole group or individually at a center.

Batteries can be classified under two major categories:
- Primary Batteries
Primary Batteries are non-rechargeable batteries. Once these batteries are completely discharged, they can not be recharged. The electrochemical reaction within these batteries cannot be reversed. They need to be recycled. The devices that use primary batteries generally consume lesser energy so that the battery lasts longer, for example, wristwatches, toys, remote controllers, pacemakers etc. Alkaline batteries are the best example for primary batteries. The best part of alkaline batteries is that they are harmless to the environment, they are less expensive and they do not leak while being fully discharged. However, since alkaline batteries have low power load, they can support only those devices that require low power like remote controllers, flashlights, etc.
- Secondary Batteries
Secondary batteries are rechargeable batteries that can be recharged once the energy drains out. The electrochemical reaction in these batteries can be reversed by applying a certain voltage in the reverse direction. These batteries are used in devices that require higher amounts of energy. Secondary batteries come in a small capacity, as well as heavy capacity. The small capacity batteries are used to power portable devices like mobile phones etc., and heavy capacity secondary batteries are used in high power draining devices like electric vehicles, etc. They are also used in inverters. There are four major types of secondary batteries: Lithium-ion(Li-ion), Nickel Cadmium(Ni-Cd), Nickel-Metal Hydride(Ni-MH) and Lead-Acid.


Natural Acid Rain
One big issue these days is acid rain falling in industrialized areas of the world. Much of the acid in rain comes from nitric acid and sulfuric acid, which are released as a result of automobile exhaust and factory smokestacks. While rainwater needs to be somewhat acidic to dissolve minerals so they can be taken up by plant roots, too much acid is damaging buildings, automobiles, forests and lakes in some areas of the world.
Since acids tend to wash out of the atmosphere in rain fairly close to where they are created, scientists were amazed to find acid rain contamination in remote areas of the Amazon River basin, far from any cities. They identified the acid as formic acid, a byproduct of formaldehyde, a common industrial exhaust pollutant.
After more research, scientists discovered that the Amazon acid rain problem was being caused by ants! There is a huge population of formicine ants in the Amazon basin. These ants produce formic acid, which they store in a pouch and use both to defend themselves and to communicate with each other. Each ant might carry enough formic acid to make up five percent of its weight, which doesn't seem like very much. But when you multiply that by 100 trillion ants, you have enough formic acid to create an industrial sized pollution problem!
There are indeed problems on this Earth. The Bible warns us that the Earth is wearing out like a garment. Our Creator will soon come for us, and then there will be a new heaven and a new Earth!


Fly fishing and water plants
Judging your waters in fly fishing also involves observing aquatic plant life. Check out the kinds of underwater plants present, rather than surface ones like lilies or border plants. A good sign of a water being alkaline is an abundance of underwater plants with large leaves. But if you observe only small slender plants, the water is more likely to be acidic.
Large underwater plants – for example Potamogeton praelongus – mean plenty of food and cover for fish. Not only that, but these plants produce oxygen as well. In clear waters you will see streams of bubbles rising from thick mats of plants on a lake bed. An anchor may pull up mats of plants which will contain plenty of insect life. Exceedingly clear lakes allow oxygen at greater depths, so because plants will be found at bottom in deep water, you can expect trout to range down there as well.
To recap what we said before, there are many factors you should take into account before you even start fishing. There is an art to judging waters. If you take a look at previous blogs on the subject take note of the few basic tips we offer on considerations such as water depth and clarity, acidity or alkalinity, and plant life. Developing your observational skills in this matter alone can only help improve your fly fishing skills.


Canada’s CBC News is reporting on a study showing a way to possibly prevent one type of skin cancer. A Stanford dermatologist found that a commonly used anti-inflammatory can reduce the risk of basal cell carcinoma:
In a small, double-blinded, randomized, three-year clinical trial of 60 people genetically predisposed to basal cell carcinoma, a type of skin cancer, researchers found that those who took 200 milligrams of celecoxib (Celebrex and Onsenal) orally reduced the number of tumours by 50 per cent.
From lead researcher Jean Tang, MD, PhD: “Basal cell carcinomas are the most common human cancer in the United States, and their incidence is increasing steadily. This work identifies a possible way to prevent them.”
Tang’s work appears in the Jan. 5 issue of Cancer Prevention Research. More on the study can be found in this release.
