Family: Gadidae, Cods view all from this family
Description The Atlantic cod, Gadus morhua, is a well-known demersal food fish belonging to the family Gadidae. It is also commercially known as cod, codling or haberdine.
In the western Atlantic Ocean cod has a distribution north of Cape Hatteras, North Carolina, and round both coasts of Greenland; in the eastern Atlantic it is found from the Bay of Biscay north to the Arctic Ocean, including the Baltic Sea, the North Sea, Sea of the Hebrides, areas around Iceland and the Barents Sea.
It can grow to 2 meters in length and weigh up to 96 kilograms (210 lb). It can live for 25 years and sexual maturity is generally attained between ages 2 to 4, but can be as late as 8 years in the northeast Arctic. Colouring is brown to green with spots on the dorsal side, shading to silver ventrally. A lateral line is clearly visible. Its habitat ranges from the shoreline down to the continental shelf.
Several cod stocks collapsed in the 1990s (declined by >95% of maximum historical biomass) and have failed to recover even with the cessation of fishing. This absence of the apex predator has led to a trophic cascade in many areas. Many other cod stocks remain at risk. The "Atlantic Cod" is labelled VU (vulnerable) on the IUCN Red List of Threatened Species.
Dimensions Up to 6' (1.8 m); 98 3/4 lbs (44.8 kg).
Habitat Ocean or bay shallows, Open ocean.
Range New England, Mid-Atlantic, Southeast, Eastern Canada.


Make marmalade this winter
Citrus is the star of winter. When not a lot else is in season it is sweet, colourful and cheap.
Many people who grow citrus are faced with the problem of how to eat it all.
If you have a citrus tree, it is best to leave the fruit on the tree and pick as needed. Citrus can stay good for months on the tree. The longer they stay on the tree, the sweeter they get.
If you have bought or been given citrus, keep them in the fridge until you want to eat them - they will last for a couple of weeks at least.
Should you have more fruit than you can handle, contact Community Fruit Harvesting. They collect excess fruit and turn it into preserves and cordials which are donated to foodbanks.
Making marmalade is a great way to preserve citrus for the coming year. The beauty of this recipe is that you can use any sort of citrus – limes, grapefruit, oranges, tangelos etc - or mix them up for a wonderfully tangy spread. Keep the skin on the fruit so that nothing goes to waste!
- About 1.6kg citrus fruits
- 1.5 litres (6 cups) water
- 2 lemons
- 1.25kg (5 cups) sugar
- Cut fruit into quarters and slice finely. Put into a large bowl and cover with the water. Allow to stand overnight.
- Tip the fruit and water into a large pan, bring to the boil and simmer covered until the rind is very tender (40-60 minutes depending on how finely you have cut the rind).
- Add the sugar and stir until it has dissolved. Increase heat and boil uncovered until it gels when tested on a cold saucer. This will probably take at least 45 minutes. Pour into hot, sterilized jars and seal. The unopened jars will keep for up to a year.

The son of Solomon during whose reign the kingdom divided into north and south.
Rehoboam succeeded his father Solomon as king of the united monarchy. He ignored the counsel of the elder advisors and continued the heavy taxation that Solomon had levied to maintain the administrative structure of the united kingdom. The northern kingdom therefore revolted and instituted their own monarchy, crowning Jeroboam I king of the northern tribes, which became known as Israel. Rehoboam continued to reign over the southern kingdom, Judah, for 17 years.

“We stand, in most places on earth, only 6 inches from desolation, for that is the thickness of the topsoil layer upon which the entire life of the planet depends.” (R Neil Sampson)
Usually the only magazines I buy are The Big Issue and a TV guide but recently I bought an issue of Country Life because HRH The Prince of Wales was guest editor. He has run Duchy Home Farm organically for 30 years and he understands farming.
One topic Prince Charles wrote about was soil. Research by University of Sheffield suggested that the nutrients in the soil will run out in 100 seasons if we carry on as we are. Other researchers think 60 years unless we start to reintroduce more sustainable practices now. Forty percent of the world’s agricultural soil is now classified as either degraded or seriously degraded (meaning that 70% of the topsoil is gone). Our soil is being lost at 10 to 40 times the rate it can be replenished. In some parts of the world over-intensive farming has created desert.
Growing plants use 60 minerals and trace minerals which they draw from the soil. Artificial fertilisers do not replace all these trace elements; they focus on three that make plants grow quickly and give high yield: nitrogen, phosphorous and potassium. Sadly this means that the mineral content of our food is reducing. Animals and people need diverse minerals. As the soil becomes depleted, we can suffer from deficiencies that affect our health.
We often see farmers muck-spreading in Cumbria; it gives the land ‘heart’. Don’t moan about the smell, rejoice in the goodness going back into the soil!
Top tips – support our good local farmers.


The kelvin (abbreviation K), less commonly called the degree Kelvin (symbol, o K), is the Standard International ( SI ) unit of thermodynamic temperature. One kelvin is formally defined as 1/273.16 (3.6609 x 10 -3 ) of the thermodynamic temperature of the triple point of pure water (H 2 O).
The kelvin scale differs from the more familiar Celsius or centigrade ( o C) temperature scale; there is no such thing as a below-zero Kelvin figure. A temperature of 0 K represents absolute zero, the absence of all heat. However, the size of the kelvin "degree" is the same as the size of the Celsius "degree." A change of plus-or-minus 1 o C is the same as a change of plus-or-minus 1 K.
At standard Earth-atmospheric sea-level pressure, water freezes at 0 o C or +273.15 K, and boils at +100 o C or +373.15 K. A temperature of 0 K thus corresponds to -273.15 o C. A temperature of 273.15 K corresponds to 0 o C. To convert a kelvin temperature figure to Celsius, subtract 273.15. To convert a Celsius temperature figure to kelvin, add 273.15.

Fall Prevention Programs North Adelaide
Preventing falls – maintaining safety
Falls: a significant issue can be prevented.
Falls are a significant concern, especially as we age. 1 in 4 people in Australia aged over 60, and 1 in 3 people aged over 65, suffer from falls each year. These falls can result in significant mortality and morbidity, as well as affecting confidence and quality of life.
Falls are not simply a normal part of ageing, but rather something that can occur due to a number of different factors. These can include changes in health, muscle weakness, reduced balance, medications, reduced vision and hearing, and external environmental hazards.
Body Fit Physiotherapy’s experienced team can help you understand the factors contributing to your falls and put strategies in place to address these, helping you reduce your risk of falls – and maximise your safety and quality of life.
What to expect in our fall prevention programs:
Detailed assessment and history taken to understand contributing factors to your falls
Education on these contributing factors, and things you can be doing to help minimise your risk
Individualised falls and balance training, working on your balance in a safe and supervised environment


Hesitation Markers in English, German, and Dutch
de Leeuw, Esther
MetadataShow full item record
de Leeuw, E. (2007) Hesitation Markers in English, German, and Dutch, Journal of Germanic Linguistics, vol. 19, , pp. 85-114,
This study reports on a number of highly significant differences found between English, German, and Dutch hesitation markers. English and German native speakers used significantly more vocalic-nasal hesitation markers than Dutch native speakers, who used predominantly vocalic hesitation markers. English hesitation markers occurred most frequently when preceded by silence and followed by a lexical item, or when surrounded by silence. German and Dutch hesitation markers occurred most frequently surrounded by lexical items. In Dutch, vocalic-nasal hesitation markers dominated only when surrounded by silence. Vocalic-nasal hesitation markers dominated in all positions in English and German, although in the former language this was more salient than in the latter. Nasal hesitation markers were used significantly more frequently in German than in English or Dutch. In addition to overall language trends, speaker-specific differences, especially within German and Dutch, were observed. These results raise questions in terms of the symptom versus signal hypotheses regarding the function of hesitation markers.* 1. The Function of Hesitation Markers.


Allergies – More Information
llergies, Eczema and Asthma are the most common conditions I see as chronic disease that are referred in my office.
I see patients come in with these conditions from 4 months old to our soon to be college students.
Most of the time, the patients are on Benadryl, Claritin or Zyrtec.
When that fails, they are on a nasal or inhaled steroid.
They have their albuterol puffer of course.
And that is it….
Some have allergy tests. Others have not been tested.
Most patients are pretty much stuck there and feel like they have few other choices.
It is amazing, as we investigate and start different types of therapies, how much they individual improve.
Most will come off all their medications.
Some need support from time to time.
Most families become empowered in what caused their condition as well as extensive knowledge and many modalities on what to do if things flare up.
Below are some statistics from the American Lung Association.

If nature won't cooperate then why not take control. If for example through genetic manipulation you still don't succeed in creating the perfect crop or animal then why just not create one. Currently Australia is the leader in the enhancement of life through genetic modification techniques. In Australia they happily practice techniques that are forbidden everywhere else. But what consequences does that have on the process of evolution by natural selection?
Some say that genetics is nothing more than normal farming techniques with added ingenuity. For ten thousand years farmers have been giving the process of evolution by natural selection a helping hand, as Darwin called it "the process of evolution by domestic selection." In other words they've selected the traits they wanted in their plants and animals by allowing only the choice breeds to mate.
Gregor Mendel discovered that the units of genetics are not fluids but particles. He focused on one plant, the ordinary garden pea, and he remorselessly tracked down the productions of generations when he interbred them. In Australia living on a farm has become a lot easier because of Darwin and Mendel and this has nothing to do with natural selection.
But what are the rights and the wrongs of all this? Philosopher Daniel Dennett thinks that there is no reason we shouldn't tamper with nature. Everything you eat, every bit of clothing you wear is tampered. You could not survive on non-genetically modified diet, you couldn't live without it. The only difference is that now we can do the modifications lot faster, more effectively and much safer. So Europeans have been unnecessary difficult, according to Dennett.

A familiar sight in the woodlands of eastern North America, Jack in the Pulpit (Arisaema triphyllum) arrives on the scene in May, in Wisconsin. The intriguing bloom consists of a green and brown striped hood that conceals a spadix - or jack - covered in numerous tiny green to purple flowers. The unusual flower gives way to a cluster of bright red berries in late summer, which may be eaten by birds and mammals.
Unique and easy to grow, Jack in the Pulpit can be grown in any rich soil in the shade and requires very little care, other than keeping the plants covered with a thick layer of leaves over the winter.
Arisaema triphyllum plants can be either male or female and they can change sex from year to year, depending upon the success of reproduction the previous year. Males plants - usually smaller than female plants - have a small hole at the bottom of the spathe which allows pollinators to escape more easily. Female plants lack the hole and pollinators are more likely to become trapped, leading to more successful pollination.


Our heads are designed to sit neutrally on top of the spinal column so that our ears are aligned with our shoulders. Most of us in this society, however, hold our heads in an unnaturally forward position that creates strain on our necks (often causing headaches), rounding of our shoulders (reducing mobility), misalignment of the spine from its natural curves, and even reduced breathing capacity.
This often happens because of the time we spend on computers and other sedentary tasks that are performed with poor posture. The challenge is that most of us are entirely unaware that we are not holding our heads in alignment. How often do we even stop to think about where our heads are relative to the rest of our bodies? Given the amount of time that most of us spend “in our heads,” it’s ironic that we so seldom know where they are!
Yoga practice can be very helpful in teaching us to become aware of where our heads are and in learning to hold them in a more neutral position. Many postures, like tadasana (Mountain Pose), include a focus on holding our heads in alignment. However, it is also easy to create additional strain to an already challenged neck with other yoga postures are performed without taking stock of our head placement.
Yoga Journal has a wonderful article by well-known yoga teacher Richard Rosen called Get to the Root of Neck Problems that is full of suggestions for ways to use assistance from a partner to discover what it feels like hold your head in a neutral position. Given the many negative effects of holding your head too far forward, it’s well worth the time it takes to find out where your head should be so you can begin to retrain yourself to be aware of the location of your head relative to the rest of your body.
Do you know where your head is?

What is Judo?
Judo (gentle way) has its roots in ju-jitsu, an ancient and brutal Japanese self-defence system used by the samurai. In 1882 Jigoro Kano created Judo from Jujitsu as a modern martial art and combat sport. In competition the object is to either throw or takedown the opponent to the ground, immobilize or subdue them with a grappling technique or force them to submit by joint locking or applying a strangle hold or choke. The art of judo (but not the sport) also contains hand and foot strikes as well as weapon defences. These are demonstrated and practiced through kata (pre-arranged forms).
Judo is suitable for all age groups, abilities and genders. It is a very popular martial art and the British Judo Association has over 1000 clubs registered with it, including the Washington Judo Club…

Hi everyone, wondering if anyone can help me with this little problem... An object with mass m1 , resting on a frictionless horizontal table, is connected to a cable that passes over a pulley and then is fastened to a hanging object with mass m2. Find the acceleration of each object and the tension in the cable. For this coordinate system, where the x-axis is pointing to the right, which is the positive, and the y-axis is pointing downwards, which is positive: http://www.imagehosting.com/show.php/1011793_Coordinate.bmp.html Given that T is the tension, the equations should be: m1*(a) = T; m2*(a) = -T + m2*(g); However, if i switch the x-axis from pointing rightwards to pointing leftwards, i will get this: http://www.imagehosting.com/show.php/1011808_Coordinate1.bmp.html The equations become: m1*(a) = -T; m2*(a) = -T + m2*(g); I am confused as to how to solve this using the 2nd coordinate system, as i feel that coordinates should not affect the answer. My question is that what is it that is wrong in my equations that i cannot get the answer? Or is it possible that this assumption is flawed? I feel that maybe the tension have to opposite each other (having opposite signs) regardless of coordinates, but i am not very sure. Thanks to all for your time.


Regiomontanus and Calendar Reform
Image by kind permission of the Master and Fellows of Trinity College Cambridge.
According to the Liber Chronicarum (Nuremberg, 1493) of Hartmann Schedel, Regiomontanus' fatal trip to Rome in 1476 was prompted by the summons of Pope Sixtus IV, who wished to engage the astronomer in a reform of the calendar. This story is rendered plausible by the fact that Cardinal Bessarion, Regiomontanus' former patron, had raised the matter of errors in the calculation of the date of Easter with the former pontiff, Paul II, in 1470, in all probability relying upon a tract which Regiomontanus had written on the topic during his time in Rome. It was most likely this work which Regiomontanus proposed (in his 1474 tradelist) to publish in Nuremberg.
The issue of calendar reform was also raised in Regiomontanus' calendars for 1475-1531. Here he pointed out that errors resulted from incorrect assumptions about the length of the year and the changing lunar phases, and named 30 instances between 1477 and 1532 when the ecclesiastical calculation of the date of Easter and the correct date would differ. Perhaps in recognition of the sensitivity of the topic, this section was only included in the Latin version of the calendars and omitted from the German edition issued at the same time.


Module 3: Gender in Teaching and Learning
Gender and power relations are intrinsic to all social institutions, and this is especially relevant for academic institutions. Gender constructions and relations begin at home, but stereotypes are also reinforced through teachers‘ behaviour, social interactions at university and the curriculum there. This workshop seeks to expand the gender perspective and skills of teachers at university. The methodology is participatory and includes discussions, brainstorming and group work. It intends to increase gender responsiveness and sensitivity to teachers.

The current political and cultural polarization in the United States and other countries has significant implications for all educational institutions and for libraries and librarians. The interrelated issues of trust, credibility, and authority now present major challenges because of the uncertainty of the social media environment, competing information “bubbles,” and enduring cognitive biases. The accelerating fragmentation of the media and information ecosystems undermines communal understanding of large and complex issues that citizens must face. To address this profound societal challenge, academic librarians should collaborate with faculty members to create communities of inquiry for students—sustained “high impact practices” that address the complexity of the current information environment. This article shows one model for using the Framework for Information Literacy for Higher Education to create learning goals for a range of in-depth learning experiences that cultivate habits of mind essential to discernment in the current political and cultural climate.

William Jennings Bryan, 1896
Bryan's oratorical gifts easily won him the Democratic nomination over rival Richard, "Silver Dick," Bland. 1 Again, the most pressing issue was whether America should stay on the Gold Standard. Really. People got het up about that in those days. Republican candidate William McKinley was for the Gold Standard, and Democrat Bryan was against it. What was at stake was how much currency would be in circulation. Bimetalism meant more currency - ie, easier access to dough - which would benefit farmers. Sticking to gold meant lower inflation and a sounder dollar which was good for the Big-Money Interests. In this go-round, the Big Money Interests won out. Thank goodness. Bryan had grown up Baptist, Methodist, and Presbyterian, so he'd swallowed three times the recommended dosage of religion. Historians agree Bryan was an upright, deeply moral man of profound ethical convictions, which is the sort of thing that's bound to get you in trouble sooner or later. He swore he would not allow America to be "crucified on a cross of gold." As far as I know, we never were, so he ultimately won that go-round even though he didn't win the election.
William McKinley: 271
William Jennings Bryan: 176
1. He got his nickname because of his support for silver coinage, at least I hope that was the reason.

The aim of this reconnaissance was to establish any Turkish presence around Hod el Gedaidia. After the Turkish raid at Romani, it was essential to discover the Turkish presence, the numbers of Turkish forces deployed and so establish their intent. In addition, with an eye on future operations, the location of water sources and potential volumes were to be discovered by this reconnaissance.


Did you know that our bodies are really made of stardust? Since the first grade, Ken Croswell, an astronomer and Ph.D. from Harvard, has been totally fascinated by our solar system. Get caught up in his extraordinary enthusiasm as he discusses everything from Black Holes, brown dwarfs, the Milky Way, the red giant, quasars and collisions with floating matter. Croswell relates how vast our universe really is. “The observable universe does have an edge but the actual universe has no edge whatsoever. What is beyond our horizon, we don’t know,” exclaims Croswell. “The universe’s expansion is not decelerating, it is actually accelerating.” He addresses how pollution is a devastating occurrence with our planet. “Today it is very hard to see some of the stars. There is so much light pollution. Most people have never seen our own galaxy, the Milky Way, which is sad.” Croswell discusses a two-year odyssey, from inception to publication, of his incredibly awesome book comprised of photographs of space from six different continents.
Ken Croswell is a frequent contributor to Astronomy Magazine, Sky & Telescope, New Scientist, and The New York Times. He is the author of the book, The Alchemy of the Heavens (Doubleday/Anchor, 1995) and the large format book, Magnificent Universe (Simon and Schuster, 1999).

The NOSs are a family of complex enzymes that catalyze the five-electron oxidation of L-arginine to form NO and L-citrulline. They are best characterized as cytochrome P-450-like hemeproteins that depend on molecular oxygen, NADPH, flavins, and tetrahydrobiopterin. The three human NOS isoforms identified to date, ecNOS, nNOS, and iNOS, are found on human chromosomes 7, 12, and 17, respectively. Regulation of NO synthesis and release occurs at the levels of enzyme activity and mRNA synthesis. The nNOS mRNA is structurally diverse as a consequence of alternative promoters and alternate splicing. The iNOS gene is predominantly regulated at the level of transcription by synergistic combinations of proinflammatory cytokines and bacterial wall products. Changes in mRNA levels of the ecNOS following endothelium activation are mediated by altered rates of transcription as well as by the intriguing process of changes in mRNA stability. Given the essential role of the NO pathway in a wide variety of physiological and pathophysiological process, it is possible that the three isoforms of NOS contribute to polygenic genetic diversity in neurological, immune, and cardiovascular biology. Further studies are needed to determine the mechanisms of gene regulation of NOS in health and disease.


Unique to Oskāyak High School is the opportunity for students to learn with either a laptop, tablet and by utilizing the many media resources.
On any given day, students can be seen working in the media lab on video editing, creating digital music or images, working with DSLR cameras, P2 Video cameras and green screens, midi keyboards, 3D printing or scanning, or producing works on the laser engraver. Students also have access to a large format printer capable of printing on such media as photo paper, canvas, vinyl or high gloss paper. Teachers take full advantage of the smart board, digital projector and sound field in each classroom in instructing students.
The approach to technology at Osāyak is one of permeation. Rather than designating one room as a traditional "computer lab", technology is placed and accessible throughout the building where ever and whenever it is needed. Students have access to over 150 Dell and Mac laptops or 120 iPads which they can sign out and use throughout the day with existing WiFi internet.
Below are video demonstrations and product demos of some of the technology available to Osāyak students.

However, the problem is the amount of time evolution takes.
What exactly do you mean by "amount of time evolution takes"? Evolution, in the simplest terms, is just a change in a gene pool from one generation to the next. Any
statistically significant change in gene frequency is evolution. In this way evolution can occur between two generations which, depending on the reproduction time and rate of the organism, can be extremely quick if there is a drastic change in environmental conditions.
That change, though possibly imperceptible to us, is evolution.
Life on this planet has seen changes far faster than micro evolution can explain.
How so? Small, even tiny, changes can lead to massive overall change with enough time. It takes a statistical mindset to see what evolution can build with enough time. An example would be the "Would you take $1,000,000 now or a penny doubled for 31 days" thought project. Evolution builds upon previous change to create more change. And then that change is compounded by more change. And on and on.

The lessons on Fossils were targeted to the Science and Technology for Children (STC) unit Rocks & Minerals and the Full Option Science System (FOSS) unit Earth Materials. These lessons, developed and piloted by classroom teachers, were designed to take advantage of the opportunity to integrate reading and writing into science.
The Fossils lessons will help your students understand that fossils provide evidence of plants, animals, and environments that existed long ago as well as understanding that plant and animal species change over time. We suggest these lessons fit just after Lesson 3 in the Rocks & Minerals (STC) unit and at the end of the Earth Materials (FOSS) unit.
If you are an individual teacher, check with your Materials Science Resource Center (if your school district has one) to see if the Fossils Lessons are already in the kit. If you do not have a Materials Science Resource Center, here are the resources you will need:
- Fossils Lessons
- Fossils PowerPoint
- Geologic Cross Section Image

These worms truly are gigantic, and can grow to lengths of roughly eight feet. They are characterized by their bright red "plume" which is actually a hemoglobin-rich organ that siphons chemicals to the bacteria. The outer tube of the worm is comprised of chitin, the same material that makes up the exoskeletons of crustaceans. When threatened, the plume will retract in to the tube.
Giant Tube Worms reproduce through spawning; eggs are released into the water and are then fertilized. Young worms then eventually hatch and attach themselves within a worm community. No one is really sure how the young worms obtain their symbiotic bacteria, or how they find vents to attach themselves near. We do know, however, that Giant Tube Worms have remarkable growth rate, as they are able to reach a length of about five feet in roughly two years.

Fire is a daunting human ecological challenge and a major subject in science and policy debates about global trends in land conversion, climate change, and human health. Persistent environmental orthodoxies reduce complex burning traditions to overly simplistic representations of environmental destruction, degradation, and loss while reinforcing existing social inequities involving smallholders. Fire Otherwise: Ethnobiology of Burning for a Changing World advocates for a more inclusive and pluralistic fire ecology, a shift from the paradigmatic globalized version of fire science and management towards approaches that embrace anthropogenic fire regimes and broader understandings of the ways humans interact with fire. The authors present new evaluations of human interactions with fires in contexts of changing environmental conditions. Through deep description and analysis of knowledge and practices enacted by local communities who ignite, manage, and extinguish fires, this collection of case studies supports proactive local and regional efforts to adapt amidst continually changing social and ecological circumstances. The book includes chapters addressing fire use and management by Indigenous peoples in the Brazilian cerrado and Gran Sabana of Venezuela, quilombolas in the Jalapão region of Tocantins, and swidden farmers in Central Amazonia.

War Is The Enemy Of Breastfeeding
The babies arrive small and skinny. To a health worker's eye, it's clear they're not growing well, though it's often only a health crisis like a fever or severe diarrhea that leads their mothers to make what is almost always a long trek to the Al Salam Hospital in Khamir, Yemen.
"By then, the babies are too weak to breastfeed," says Fiona Bay, a nurse with Medecins Sans Frontieres (Doctors Without Borders) at the hospital.
The neonatal unit of Al Salam in the war-torn country is seeing an increasing number of malnourished infants, and providers say that mothers are reporting that they cannot breastfeed their babies. Studies on breastfeeding in a conflict zone are scarce, but a few suggest that war and violence are tremendous obstacles to a mother's ability to breastfeed her baby.

Don’t look now, but your face might be home to a group of tiny creatures!
These organisms, called demodicids, or eyelash mites, live on the bodies of even the cleanest of people. Demodicids are tiny parasites that live in pores and hair follicles around the eyelashes. They feast on dead skin cells and oils that accumulate there. The parasites resemble semi-transparent worms, and have four pairs of short legs they can use to get around.
You might not have heard of them, but demodicids are extremely common in humans. Researchers estimate that a small number of mites live on the faces of most adults, and the infestation becomes more and more common with age. In fact, as many as 96% of elderly people are thought to carry these microscopic mites.
Although the presence of parasites on so many people might sound alarming, demodicids are harmless and don’t transmit diseases. In some people, usually those with extremely oily skin, or those who use cosmetics heavily, large numbers of mites can develop. This large population can cause an itchy skin condition called demodicosis. However this condition is quite rare, and most people will never even know about the tiny creatures sharing their personal space.
If you’re curious, you can easily discover if any demodicids reside on your face by looking at one of your eyelashes through a microscope. However, be forewarned–you just might find mites there!


Pedopmorphy refers to an evolutionary process in which adult animals maintain the traits of juveniles. One fairly easy way for genetic mutations to produce physical changes in the animal is to adjust the timing of maturation. No new physical structures or behaviors need to be introduced; the animal simply maintains its youthful traits instead of shedding them when it reaches maturity. There is evidence that many advances in human evolution involve pedomorphy. For example, we are one of the few mammals that retain a high level of playfulness throughout adulthood. Secondly, the shape of our skull mirrors that of juvenile apes. The skulls of juvenile chimpanzees look more like the skulls of adult humans than the skulls of adult chimpanzees. Adult chimpanzees have small sloping foreheads, prominent jaws, and more horizontally-aligned faces. Adult humans, on the other hand, have high foreheads, small jaws, and flat, vertically-aligned faces, similar to juveniles of both species. Of note, juvenile chimpanzees have a larger brain to skull ratio than do adult chimpanzees. In humans, this favorable ratio is retained into adulthood.


SAN JUAN CAPISTRANO, Calif. (KABC) -- As researchers learn more about the dangers of concussions, one Southern California high school is taking extra steps to care for its football players.
JSerra Catholic High School in San Juan Capistrano will begin using a new brain scanning technology to test for concussions.
Measuring the speed, voltage and reaction time of the brain, the baseline scan may be able to help JSerra protect student-athletes from future head injuries.
It's the first time any high school in Southern California has conducted these types of brain scans.
For the athletes, it offers some peace of mind. But parents may appreciate it even more.
"Making us aware now and taking precaution is the best thing we can do for our children," Susan Angel said.
JSerra admits head injuries are a big concern among its athletes and their parents.
"We just really want to have the safest environment for our athletes, not just when they're participating in their sports or their future sports in the collegiate or professional levels, but also just for life," JSerra Athletic Training Director Kayla Gradillas said.
JSerra will be administering testing starting with football players, but the school plans to expand the testing to all of its athletes soon.

Spring has sprung, and while it is usually a time of year associated with new life and the pitter patter of tiny animal feet, there is a new place where breeding is taking place and it’s not the lush green fields or flowering meadows that you might expect. In fact, it’s not even on land. Playing environmental matchmakers, scientists have successfully begun breeding baby coral on the Great Barrier Reef.
It’s a move that may have worldwide significance, and certainly a unique way to strengthen and restore one of Australia’s most famous natural wonders. Southern Cross University professor and lead project researched Peter Harrison discovered mass coral spawning in the 1980s and says it provides a glimmer of hope for the future of the reef.
“The results are very promising. The success of this new research not only applies to the Great Barrier Reef, but has potential global significance. It may (also) be one of the answers to some of the problems in the Great Barrier Reef “Prof Harrison said.
So, let’s talk about the birds and the bees. Sperm and coral eggs were collected during coral spawning last November from Heron Island reef. These were used to produce over a million larvae which were returned to reef patches in mesh tents to protect them. 100 of these larvae managed to survive and are now growing successfully.
The project aimed to restore damaged coral populations and has already seen success in parts of the Philippines where coral has been destroyed by blast fishing. Great Barrier Reef Foundation managing director Anna Marsden says it’s an important step, but one that shouldn’t solely be relied upon to lessen the impact of climate change.
"There is much more to be done, but this is definitely a great leap forward for the reef, and for the restoration and repair of reefs world-wide. It's time to be bold and take some calculated risks because that's the way we'll make a change in how we can help restore our coral reefs," she said.


Voyage Update 2: Salp Cycle 1 is going well…
30 October 2018. By Voyage Leader Dr Moira Decima.
The cold-water salp Salpa thompsoni has dominated the catch, and we have done multiple tows to know their abundance (how many), and are carrying out experiments to investigate what they eat, how many faecal pellets (poop) they produce, and how fast these sink. These pellets both help transport carbon from CO2 at the surface to depth, and are food for the animals that leave in the deep sea.
We also want to know the population of S. thompsoni, so we look at the different stages and sizes of zooids in the water. We count and measure the oozooid (solitary, asexual) and blastozooid (aggregate, sexual) animals are in our nets.
We are finding that the oozooids (solitary) S. thompsoni have really been cranking out their zooid clones! If you look closely, you can even count the blastozooids (clones) in the stolon that will soon be released by the oozooid. There is a double row of them, and the tiny white areas are the guts of the newly produced female blastozooids. These will then go on to be fertilised, produce an embryo, and later turn into males to fertilise more females!
With their complex life style, using both asexual (clones) and sexual reproduction, salps can bloom very quickly and dominate the plankton community.


Last year marked 100 years since the end of The First World War. Given that communications were far less effective and much slower than what we know today, advertisements became an essential means of boosting morale and letting everyone know how they could contribute their help.
There’s still plenty to be learned from the World War I posters – from their mistakes through to their triumphs. Promotional print company, Where The Trade Buys, has compiled a collection of some of the most creative and iconic posters of World War I. See if you recognise any?
A female recruitment poster: The Women’s Land Army
Women’s Land Army (WLA) recruitment posters are some of the most remembered wartime memorabilia from World War I and II. By the end of the first year of World War I, more than one million men had been recruited to the British Army — a number that hit around five million by the end of the conflict. As a result, the country was suffering from a significant workforce shortage and needed to employ the help of women to feed the people left at home.
A message of equality
The aim of this ad — launched in World War I — was to encourage young women to take over jobs in agriculture. Often referred to as ‘Land Girls’, some farmers were hesitant or even completely against using female workers, despite the dire situation. Others even felt that the choice of WLA uniform was too masculine.
So, why did this work? To someone who was deemed unsuitable to participate in front-line combat for her country and who perhaps wanted to break free of the domesticated lifestyle and dress code that she was compelled to follow, this image of a woman dressed in loose dungarees and working in a … Read the rest


(Knowledge Science) The benefits of chocolate
The benefits of eating chocolate:
1. Chocolate can ease the mood and make people excited.
2. Chocolate has a role in concentration, memory and intelligence. Some drivers use chocolate as a spiritual booster to improve their driving ability. Students who take the test can also be used to brain.
3. Eating chocolate is beneficial to control the content of cholesterol, maintain the elasticity of capillaries, and have the effect of preventing and treating cardiovascular diseases.
4. The amount of catechins contained in chocolate is as much as that in tea. Catechin can enhance immunity, prevent cancer, and interfere with blood supply to tumors.
5. Chocolate is an antioxidant food that has a certain effect on delaying aging.
6. Chocolate is rich in carbohydrates, fats, proteins and various minerals. The body absorbs and digests it quickly. Therefore, it is called “a midwifery” by experts. If the mother eats properly before giving birth, Some chocolates can get enough strength to make the mouth of the uterus open as soon as possible, and the delivery is smooth, which is very beneficial to both mother and baby.


WHAT IS EXACTLY A BERYL?
Beryls are Gemstones that come in a variety of colors.
The most popular varieties being; Emerald, Aquamarine, Yellow Heliodor and Morganite.
Beryl is found in Europe in Norway, Austria, Germany, Sweden (especially morganite), Ireland and Russia, as well as Brazil, Colombia,
Madagascar, Mozambique, Pakistan, Afghanistan, South Africa, the United States, and Zambia.
A more unique Beryl we would like to focus on is the Golden Beryl, what is it exactly?
With its sun-kissed hues and fine transparency, Golden Beryl is a cheerful addition to any jewelry wardrobe.It is perhaps the least-known member of the Beryl gemstone family, which includes Emerald and Aquamarine.
It was first discovered in Namibia in 1913 in a pegmatite that also produced Aquamarine.
Today, it is sourced primarily from Brazil and Madagascar.
Golden Beryl should not be confused with Heliodor, another variety of Beryl gemstone.
The two stones can be distinguished by their coloring: Golden Beryl is a warm, bright yellow, while Heliodor is a pale yellow-green.


Welcome to HIPAA Guidelines 101
HIPAA, which stands for the American Health Insurance Portability and Accountability Act of 1996, is a set of rules to be followed by doctors, hospitals and other health care providers. HIPAA helps ensure that all medical records, medical billing, and patient accounts meet certain consistent standards with regard to documentation, handling and privacy.
Is Your Facility HIPAA Compliant for 2012?
Any healthcare provider that electronically stores, processes or transmits medical records, medical claims, remittances, or certifications must comply with HIPAA regulations. HIPAA does not require a practice to purchase a computer-based system as it applies only to electronic medical transactions.
HIPAA requires that all patients be able access their own medical records, correct errors or omissions, and be informed how personal information is shared used. Other provisions involve notification of privacy procedures to the patient. HIPAA provisions that have led in many cases to extensive overhauling with regard to medical records and billing systems.

|Latin Name:||Apium graveolens|
|English Name:||Celery, Celery seeds|
|French Name:||Céleri, graines de céleri|
History and Origin
Celery used to be called “ache”, from Latin term apia, meaning “growing in water” which refers to the natural environment of the plant. Originally, it designated a group of plants (including parsley and lovage), it acquired only after the restrictive meaning of “celery”. First documented in 1651, the word “celery” comes from the Lombard seleri, derived from Latin selenon. This name refers to the belief that the plant was under the influence of the moon (sele), possibly because of the aphrodisiac properties then associated to it. The term “celery” definitely replaced “ache” in the common language, although this term is sometimes still used in botany and herbalism.


Flowering cover crops can suppress weeds while providing floral resources for beneficial insects
Incorporating cover crops into crop rotations is known to have many benefits to soil health and ultimately crop yield. However, they are often prevented from flowering--which would support pollinators--because of fear that the cover crops will set seed and later become weeds. A recent study published in the journal Environmental Entomology shows that when some cover crops are allowed to flower, they not only provide important resources for pollinators, but they can also help suppress weeds in future crop rotations. The study compared floral resources, weed diversity, and economic weed abundance in crop fields across five cover-cropping treatments: one without cover crops (fallow), three with different combinations of flowering over crops, and one with non-flowering wheat. The flowering cover-crops provided the most food resources for pollinators, as expected. However, weed diversity was surprisingly highest in the field without cover crops. Weed diversity was lowest in the field with wheat as a cover crop, but wheat did not provide resources for pollinators. Weed diversity was measured at intermediate levels in the flowering cover-crop treatments, and interestingly, there were no differences in weeds of economic concern across the treatments. This indicates that allowing cover crops to flower and provide food for pollinators may not significantly impact crop yield in later rotations, creating a win-win situation for the farmer and biodiversity.

Hydrates – solid, ice-like crystals that form from water in natural gas pipelines and processing facilities can inflict serious consequences. To combat hydrate formation, operators inject methanol, which lowers the freezing point of water and eliminates freeze-ups. For a network system that consists of hundreds of miles of pipelines across varying terrains, predicting how much methanol to inject and where to inject it is a particularly complex task.
By leveraging simulation data from PIPESIM, a steady-state multiphase flow simulator, Geminus developed a surrogate of an example pipeline network to capture system hydraulics with high accuracy. Download the full case study to learn more.

The History of Nail Polish – Babylonia
We have been researching the history of nail polish, which is more complicated than it sounds. There are several theories about where colouring nails originally came from, however we think that it comes from the henna decorations of India during the Bronze Age.
Although are pretty sure we can credit India with the creation of nail polish itself, the Babylonians definitely invented the manicure.
Not Much Colour Choice
The Babylonians took nail colouring to an entirely different level, using it to signify social status. Black was the colour of choice as it signified a high social status, while green was only used on the nails of lower classes. Instead of henna that the Indians used, the Babylonians used kohl to decorate their fingernails.
These days there are a number of nail techs to choose from, but back in ancient Babylonia they were clearly in high demand and making good money. Excavated royal tombs (that date back to 3200 B.C.) have unearthed well-preserved solid gold manicure tools along with the original kohls.
Oh, the Irony
In an ironic twist, the girly ritual of the manicure was originally reserved for men… warriors in fact. Although it’s likely women of high classes & royalty may have had their nails done as well, painted nails & their indication of class status was largely male-dominated.
Babylonian warriors didn’t jog or do calisthenics before going into battle, they prepared by having their hair & nails done!

If you haven’t yet seen were it all began, be sure to check out how the Indians invented nail polish and stay tuned to see how the Chinese adapted this fabulous trend.


Color-coded topography map of Juventae Chasma. White and red show the highest terrains, while blue and purple show the deepest.
The floor of Juventae Chasma sits some 5.8 km below the surrounding plateau. It is filled with sand in the southern part (left), which takes on a smooth appearance, in contrast to the northern (right) part of this image where many blocky rock fragments have slumped down from the chasma walls. Two large mounds of layered material sit inside Juventae Chasma and comprise minerals altered by water.
This region was imaged by the high-resolution stereo camera on ESA’s Mars Express on 4 November 2013 (orbit 12,508), with a ground resolution of 16 ms per pixel. The image center is at about 4°S / 298°E.

Test of open/short
Ground all pins of the IC (including Vdd/GND).
Set the voltage limit to 3V.
Use PMU force +100μA onto the pin to be tested and measure the voltage.
If the measured voltage value is greater than a specific value (such as 1.2V), it is judged as Open, if it is less than a specific value (such as 0.1V), it is Short.
Test of leakage
Test of pattern
Take "AND gate" as an example, input a set of signals, measure the output pin, and compare it with the expected value.
The row of the truth table is called vector or pattern, and the number of rows in the truth table is called vector/pattern depth.
Program the Pattern using the IDE environment, compile and generate a truth table, and load it into the business board.
The test machine automatically executes the corresponding input of the pattern, judges the output result, and notifies the sorter to classify.


Earthquake In Pakistan Creates New Island In Arabian Sea
A massive earthquake in Pakistan has resulted in the birth of a new island:
A major earthquake struck southwestern Pakistan earlier today killing over 100 people; injuring thousands more; collapsing building and houses; and, incredibly, causing a small island to form in the sea off Pakistan’s coastline.
The U.S. Geological Survey said the quake that hit Pakistan’s Baluchistan province early Tuesday morningwas a 7.8 magnitude. Officials recently said that at least 150 people died during the quake, with that number expected to rise as the Pakistani military continues the clean up. Many one-level houses in the impoverished area where the quake hit collapsed on the people inside.
In addition to the physical damage, the power and force of the quake was underscored by the small, visible island that rose off the coast of Gwadar in the Arabian Sea. Reuters reports ”a crowd of bewildered people [gathered] on the shore to witness the rare phenomenon.” Pakistan’s Geo News reports ”the island’s altitude is 20 to 40 feet and width around 100 feet,” and that the island is roughly 350 feet off shore, citing deputy inspector general Moazzam Jah. Arif Mahmood, the head of Pakistan’s meteorological department, says they’re planning to investigate further.
The new island is certainly interesting because most earthquakes rarely have such a drastic effect on the world surface. The last time an earthquake caused such a drastic change, according to i09′s Annalee Newitz, was when an 8.8-magnitude quake in Chile altered the country’s coastline.
While this is fascinating, it’s worth noting, as the linked article goes on to note, that there is a good possibility that the death toll from today’s quake, currently around 100, could rise substantially as the extent of the damage becomes clearer.


Monolithos. Monolithos is a traditional mountain village in the central west part of the Greek island of Rhodes. It is located 70 kilometers (43 mi) southwest of Rhodes town. You’ll travel about an hour and a half by car to get there from Rhodes town.
Monolithos is a village located in a green natural site. The village has narrow alleys and lots of stairs. Accessible via a dirt road is the medieval castle of Monolithos, which is just outside the village, on top of large rocky mountain. The village of Monolithos owes its name to the rock, because “Mono Lithos” means single or only rock.
This castle was originally built by the Byzantines and later, around the year of 1476, the Knights of St. John expanded the castle. This castle was built to protect the whole southwestern part of Rhodes against pirate attacks. The castle of Monolithos was among the four strongest fortresses of Rhodes and has never been occupied.


Excerpted from introduction
Lockdown in the UK has presented challenges for families whose day-to-day lives were transformed virtually overnight.
At the start of the lockdown (23 March 2020), many people had to rapidly adjust to a ‘new normal’, with school closures, parents furloughed or working from home, and support from outside the home no longer available.
For millions of parents (or those in a parenting role), this included having to care for their children, including homeschooling them, while continuing to work.
A separate bulletin on homeschooling in Great Britain, offers insight into the challenges faced by those school closures.
Parents fitted in work commitments around childcare
Analysis of time use data has shown that many parents in Great Britain who were able to work, changed their routines to accommodate their new childcare commitments, prompted by the coronavirus (COVID-19) lockdown.
For working parents with school-aged children that said their work had been affected by the coronavirus, 20% said this disruption was at least in part because of having to work around childcare responsibilities.
During the lockdown, parents were nearly twice as likely to be furloughed (13.6%) as those without children (7.2%). This is one example of the added complications for families of the restrictions.
Those parents who worked outside of the home contributed childcare outside the usual ‘nine to five’ hours, which suggests that they were more likely to be working unsociable hours.


Six fluids that require periodic replenishment or replacement in most vehicles are the engine oil, transmission fluid, anti-freeze/coolant, windshield washer solvent and fuel. Number six, the one most often neglected, is brake fluid. You’ve known about topping off brake fluid, you may say, but changing it?
According to the Car Care Council, brake fluid in the typical vehicle can become contaminated in two years or less. This is because the fluid absorbs moisture, which works its way through the hydraulic system. Under heavy braking conditions, such as encountered in mountainous or hilly driving or when towing a trailer, moisture in the overheated fluid vaporizes (boiling point of water is lower than that of brake fluid) and braking efficiency is reduced.


Charles Prentice's father, James, studied optometry in London as an apprentice and moved to New York in 1847 to open his own optical shop. He became renowned for his manufacturing of optical instruments and creating the anatomical eye glass. As there were no adequate schools in the United States, James Prentice sent Charles to Europe to be educated in physics, engineering, mathematics and optometry.
Charles Prentice surpassed his father with acclaim and recognition throughout the world. He wrote what is now a classic essay entitled Ophthalmic Lenses. This book, however, was just the beginning of his writings and scientific discoveries. In 1910, Prentice assisted Columbia University in beginning a two-year optometry course. Now American students would not have to travel to Europe, as he had, to study optometry.
Charles Prentice helped standardize the optical field for the sake of patients' care, as well as, revamping the way the general public viewed eyeglasses. Prentice was the first optometrist to charge patients for his services. This act lead to the recognition of optometry as a profession and numerous government laws guiding and shaping the field. Prentice was one of the founding members and president of the Optical Society of the State of New York.


Manuscript vellum DS, signed “B. Franklin,” one page, 15.5 x 13.5, March 15, 1788. Franklin, as President of the Supreme Executive Council of Pennsylvania, grants “William Chambers a certain tract of land called ‘Chambersburg’ Situate in Middleton Township Cumberland County…containing Two hundred and thirty one acres and one hundred and fifty five perches.” Signed in the left border by Franklin under the large embossed eight-point seal. Intersecting folds, light show-through from a red wax seal on reverse, and expected light wrinkling, otherwise fine condition. The seal is toned and missing three of its points, yet still impressive. The Executive Council comprised the executive branch of the Pennsylvania state government between 1777 and 1790. It was headed by a president and vice president (similar to a governor and lieutenant governor), with Franklin, its sixth president, being the most well-known. His presidency was one of his last acts of public service, as he died less than two years after leaving office. At the time of this land grant, the Constitution had just been ratified, and the first US presidential election was only four months away. Pre-certified John Reznikoff/PSA/DNA and RR Auction COA.

The discovery of gravitational waves, announced in February by the Laser Interferometer Gravitational-wave Observatory (LIGO), was a groundbreaking moment for the world of physics research. It was a pretty lucky break that we happened to have a pair of ultra-sensitive instruments measuring gravitational waves pointed at a merging pair of black holes 1.3 billion years ago.
Now that scientists have had some time to noodle on the findings, they’ve begun to digest the rest of the LIGO data, and they’ve found some big implications on how the levels of cosmic background noise produced by gravitational waves is much greater that we previously thought.
For years, most scientists believed a constant stream of background gravitational noise, produced by black holes and neutron star events, was permeating the universe. Unfortunately, there was no way to actually measure and verify this theory.
In a new study published in Physical Review Letters, researchers from both LIGO and the Virgo Collaboration (essentially the European counterpart) describe how they used the binary black hole merger to estimate the gravitational radiation that would result from black hole mergers.
As a result, the researchers think there are 20 times more black hole binaries than previously estimated, and probably 10 times as much gravitational noise than we thought. Together, that means we could find more gravitational waves in just five years’ time when the LIGO and Virgo detectors are running at 100 percent.
The results are based on just a single cosmic event, so everyone keep their heads screwed on. But if that’s true, it would be great news for the physics community. Other researchers are already on the lookout for other cosmic events that could produce gravitational waves. To think we could measure more of these signals so soon was unthinkable just six months ago.


What are bow shocks, anyway?
Bow shocks form the boundary between a magnetosphere and an ambient magnetized medium. This occurs when the magnetic field of an astrophysical object interacts with the nearby flowing ambient plasma. For example, when the solar wind, flowing with a relative speed of order 400 km/s, encounters the magnetic field of Earth, a bow shape boundary forms.

Student's Difficulties with Proof
Library Home || Full Table of Contents || Library Help
|Keith Weber; Mathematical Association of America|
|"Proof is a notoriously difficult mathematical concept for students. Empirical studies have shown that many students emerge from proof-oriented courses ... unable to construct anything beyond very trivial proofs. Furthermore, most university students do not know what constitutes a proof ... and cannot determine whether a purported proof is valid." This essay addresses three questions: What is proof and what is its role in mathematics? What difficulties do students have with proofs? How can the concept of proof be taught effectively?

THE Black Country Living Museum announced this week that it will be launching 15 new characters in the autumn to help students with the revised 2014 national curriculum.
In addition to the Museum’s already strong stable of period demonstrators, the new characters will paint an in-depth picture of life in the 1900s and form the backbone of a Key Stage 2 learning engagement for schools, encouraging children to relate to people who lived in the past.
Real lives and real stories are depicted and history education takes one step closer to the present day as parallels are drawn between now and then.
These colourful personalities, in authentic period costume, encompass a wide variety of regional life.
They include a doctor, an undertaker, a chimney sweep, a flower seller, a pie man, a post woman, a Salvation Army character, a canal boatwoman, a widower, a midwife, street sellers, a working man and a pit bonk wench.
Each character has a fascinating tale to tell of life in the early 1900s and each brings Black Country memories and voices flooding back.
Mel Weatherley, Head of Learning, said: “This exciting new learning resource encourages independent thinking and query, and the development of listening and oral skills.
“Each character represents a real life and a real story and each provides opportunities for students to ask, and find answers to, valid historical questions,” added Mel.
Visitors and school groups will be able to catch more regular sightings of the new characters from September onwards.
Bookings can be made through the Museum’s ticket office on 0121 520 8054 or via the Museum’s website at HYPERLINK "http://www.bclm.com"www.bclm .com


The spotlight is shining once again on the deepest ecosystems in the ocean—Challenger Deep in the Mariana Trench (map) and the New Britain Trench near Papua New Guinea. At a presentation today at the American Geophysical Union's conference in San Francisco, attendees got a glimpse into these mysterious ecosystems nearly 7 miles (11 kilometers) down, the former visited by filmmaker and National Geographic explorer-in-residence James Cameron during a historic dive earlier this year.
Watch a video interview with Cameron on exploring deep-sea trenches.
Microbiologist Douglas Bartlett with the University of California, San Diego described crustaceans called amphipods—oceanic cousins to pill bugs—that were collected from the New Britain Trench and grow to enormous sizes five miles (eight kilometers) down. Normally less than an inch (one to two centimeters) long in other deep-sea areas, the amphipods collected on the expedition measured 7 inches (17 centimeters). (Related: "Deep-Sea, Shrimp-like Creatures Survive by Eating Wood.")
Bartlett also noted that sea cucumbers, some of which may be new species, dominated many of the areas the team sampled in the New Britain Trench. The expedition visited this area before the dive to Challenger Deep.
Marine geologist Patricia Fryer with the University of Hawaii described some of the deepest seeps yet discovered. These seeps, where water heated by chemical reactions in the rocks percolates up through the seafloor and into the ocean, could offer hints of how life originated on Earth.
And Emerging Explorer Kevin Hand, and astrobiologist with the Jet Propulsion Laboratory in Pasadena, California, spoke about how life in these stygian ecosystems, powered by chemical reactions, could parallel the evolution of life on other planets.


New data from the Home Office has shown a worrying increase in the number of fire deaths in England.
The data shows that the number of people dying in fire-related incidents in England has shown the biggest percentage increase in 20 years.
303 people lost their lives in fires in 2015-16, representing a 15% increase on the previous 12 months.
During the period 2015-16, fire services across England responded to 162,000 fires, an increase of 7,000 from the previous year.
Statistics show that of the primary fires attended
- 31,333 were dwelling fires with 229 fire-related fatalities.
- 15,984 were fires in other buildings with 21 fire-related fatalities.
Within other buildings the highest number of fires occurred in the following building types:
- Private non-residential buildings including private garages and garden sheds.
- Industrial premises including manufacturing, processing plants, warehouses and bulk storage units.
- Public buildings including car parks, public toilets, religious buildings and transport buildings.
- Retail premises.
- Food and drink premises.
The Home Office has attributed the increased death total to a rise in the number of accidental fires within people’s homes, in addition to fatalities from fires involving aircraft, mainly as a result of the Shoreham air disaster.
Data compiled by the Department of Communities and Local Government in 2015 highlighted a 14.7% decline in the number of fire fighters in the last decade. The time taken to respond to incidents has also risen over the last 6 years. The Home Office however strongly refute the claim that the rise in fire-related deaths is attributable to cuts in funding.


NSS PAN Alert June 7, 2022
Near Earth Object Surveyor Mission (NEOSM)
Some years ago an asteroid streaked through the sky above the Russian city of Chelyabinsk. An intense pulse of light drew people to their windows just in time for the blast wave to pepper them with broken glass. There was no chance to detect this asteroid before it was about to hit. NEOSM (Near Earth Object Surveyor Mission), a half meter infrared telescope under development by NASA may well have detected it in time to warn the people of Chelyabinsk but NEOSM’s budget has been slashed by tens of millions of dollars which will postpone launch by many years. About one-million asteroids bigger than the Chelyabinsk objects cross Earth’s orbit and we don’t know where they are.
If we do nothing, about 20,000 of these objects will eventually hit us. Some of those objects are big enough to destroy whole countries. We don’t have to be sitting ducks. Contact your Congressional representatives today and tell them that this is a disaster we can avoid and it is monumentally stupid to not to. Tell them to restore full funding for NEOSM.
This image of a vapor trail was captured about 125 miles (200 kilometers) from the Chelyabinsk meteor event, about one minute after the house-sized asteroid entered Earth’s atmosphere. Caption: NASA. Image credit: Alex Alishevskikh.

Summary…..being unvaccinated is far better. TOLD YOU SO.
The immune system is influenced by the history of infection or vaccination (imprinting) and vaccine response to infection is influenced by such imprinting in how immune response to infection is mounted. This imprinting influence is powerful enough that the previous history of SARS-CoV-2 infection prior to re-infection by the Omicron can influence response to the Omicron.

Microhistory is a historical research method that looks at the history of small--micro--things: specific communities; people or families; and even objects as a way to explore larger historical questions, such as "Why did so many people immigrate to the US at the end of the 19th century?" and "What were working conditions like in early 20th century copper mines?"
Individual life experiences--say, those of a 14 year old girl leaving Croatia in 1888 to work in her aunt's boardinghouse in Calumet, or those of a 21 year old Finnish trammer working 10-12 hour shifts in the Quincy mine in 1904--can help provide specific, relatable answers to those big questions about how people responded to political and economic turbulence, and changing expectations of workplace safety.
The Keweenaw microhistories presented here explore immigrant and migrant stories through primary sources from the 1500s through the early 20th century. These individuals’ life experiences can provide rich, diverse, and specific detail about the history of places, events, and communities. Pieced together, these details reveal a bigger, more complex picture of the Keweenaw’s past.

In this module, students are involved in a deep study of mythology, its purposes, and elements. Students will read Rick Riordan's The Lightning Thief (780L), a high-interest novel about a sixth-grade boy on a hero's journey. Some students may be familiar with this popular fantasy book; in this module, students will read with a focus on the archetypal journey and close reading of the many mythical allusions. As they begin the novel, students also will read a complex informational text that explains the archetypal storyline of the hero's journey which has been repeated in literature throughout the centuries. Through the close reading of literary and informational texts, students will learn multiple strategies for acquiring and using academic vocabulary. Students will also build routines and expectations of discussion as they work in small groups. At the end of Unit 1, having read half of the novel, students will explain, with text-based evidence, how Percy is an archetypal hero.
In Unit 2, students will continue reading The Lightning Thief (more independently): in class, they will focus on the novel's many allusions to classic myths; those allusions will serve as an entry point into a deeper study of Greek mythology. They also will continue to build their informational reading skills through the close reading of texts about the close reading of texts about the elements of myths. This will create a conceptual framework to support students' reading of mythology. As a whole class, students will closely read several complex Greek myths. They then will work in small groups to build expertise on one of those myths.
In Unit 3, students shift their focus to narrative writing skills. This series of writing lessons will scaffold students to their final performance task in which they will apply their knowledge about the hero's journey and the elements of mythology to create their own hero's journey stories. This task centers on ELA standards RL.6.3, W.6.3, W.6.4, W.6.5, W.6.6, W.6.1c, L.6.2, and L.6.3.


When you think of the ancient world, you probably picture towering buildings of white marble, adorned with statues also made of white marble. You’re not alone — most people picture the same thing. But we’re all wrong. Ancient buildings and sculptures were actually really colorful. The Greeks and Romans painted their statues to resemble real bodies, and often gilded them so they shone like gods. So why is seemingly every museum on planet earth full of white marble sculptures?


The Group of Eight, often nicknamed G-8, is an organization composed of eight of the most powerful and influential countries in the world. Composed of the United States, France, the United Kingdom, Canada, Germany, Russia, Italy, and Japan, this gathering of nations is of both a political and economic nature.
Their annual meetings therefore touch on a variety of pressing issues encompassed by these two major areas of concern. Since there is no set office for this organization, the role of host for the year is to provide the venue for talks, as well as take care of all other concerns related to the meetings. Logistics and security are two of the most important considerations on this list of requirements, especially since participants are high-profile officials. Furthermore, the annual G-8 talks are often controversial because of the nature of the issues they tackle.
One of the reasons why the G-8 talks are seen to be very important is that these meetings serve as a venue for discussions on international economic policies, international peacekeeping efforts, and similar areas of concern. In recent years, more attention has been given to the issue of climate change. Although this may initially be seen as an environmental issue only, the extent of change and its effects on the international economy and basic survival has made it a particularly pressing concern.
The composition of the G-8 as well as its power to influence international economic policies make it an easy target for criticism, especially from groups who are against the effects of globalization, particularly on developing nations.


The Independence Monument (Khmer: វិមានឯករាជ្យ, "Vimean Ekareach") in Phnom Penh, capital of Cambodia, was built in 1958 to memorialize Cambodia's independence from France in 1953. It stands on the intersection of Norodom Boulevard and Sihanouk Boulevard in the centre of the city. It is in the form of a lotus-shaped stupa, of the style seen at the Khmer temple at Banteay Srei and other Khmer historical sites. The Independence Monument was designed by the Cambodian architect Vann Molyvann.During national celebrations, The Independence Monument is the center of activity. A ceremonial flame on the interior pedestal is often lit by a royal or high official on these occasions, and floral tributes line the stairs. Every year, The Independence Monument is visited by foreigners and locals alike. Behind the monument is the Norodom Sihanouk Memorial, constructed in 2013.


This nonfiction picture book about the parrots of Puerto Rico and and scientists’ observations of them is a perfect STEM/STEAM titles. It is full of excellent factual information but told in a narrative that is both engaging and moves along.
The outside cover leads you to believe the book has a horizontal orientation, but upon opening it, the illustrations and text are not laid out from left to right, but from top to bottom. Each spread is colorful and dynamic collage covers three-quarters of each two-page spread.
This book is a visual delight and would serve as a great addition to studies on ecosystems, rain forests or just as a feast for the eyes.
