Eating disorders are complex mental health conditions characterized by disturbances in eating behaviors, body image, and emotions related to food and weight. These disorders often involve an unhealthy preoccupation with food, weight, and shape, leading to severe disturbances in an individual’s eating habits and overall well-being. There are several types of eating disorders, including anorexia nervosa, bulimia nervosa, and binge eating disorder. Anorexia nervosa involves extreme restriction of food intake, resulting in significant weight loss and a distorted perception of body image. Bulimia nervosa involves recurrent episodes of binge eating followed by compensatory behaviors, such as self-induced vomiting or excessive exercise, to prevent weight gain. Binge eating disorder is characterized by recurrent episodes of uncontrollable overeating without compensatory behaviors.

Thanks to EPA's National Estuary Program (NEP), more than 1 million acres of critical habitat has been sustained or restored—that's a figure that is just shy of the total area of the state of Rhode Island. The NEP, which includes 28 estuaries across the country, was developed 20 years ago to protect and restore these national resources. Stories of success and on-the-ground environmental results are evident from coast-to-coast. These examples help tell the story: • Indian River Lagoon Estuary in Palm Bay, Fla., has rehabilitated 34,943 acres of wetlands; • The Charlotte Harbor NEP restored 700 acres of Florida habitat by eliminating exotic plant species. It also founded the Babcock Preservation Partnership to save 91,361 acres from development; • 81,000 students have learned about stormwater management through the Lower Columbia River Estuary Partnership's Schoolyard Stormwater Project; • The Massachusetts Bays program has restored 13 shellfish beds; • The Barnegat Bay Program in New Jersey has saved more than 32,000 acres of critical habitat; • Coastal Bend Bays Estuary in Corpus Christi, Texas, secured $6 million to protect more than 1,000 acres of wetlands; and • The Narragansett Bay Estuary Program's dissolved oxygen surveys which documented hypoxia and anoxia in that estuary were a catalyst for Rhode Island to legislate a 50 percent reduction in nutrients from treatment plants discharging to the Narragansett Bay. The NEP was authorized under the 1987 Amendments to the Clean Water Act to improve estuarine waters, habitats and living resources by working with partners and the public.

How light or dark a colour appears is called Value. A lighter colour has a higher value than a dark colour. In order to see lines, shapes, different colours or textures, there needs to be value contrast. A highly contrasting art piece tends to create excitement and be more dramatic and attracts our eye to it. A low value contrast is more subtle and understated. A variation in value can create a focal point and can be used to emphasize something in particular. To create the illusion of depth, use a gradation of value. Thus, changes in value create three dimensions in a work, such as shading the sides of a square to give it depth and appear to be a cube. Some colours have a generally low value, such as violet. By adding white to violet, you can create a range of values. Yellow always has a high value as adding black to it soon changes it from yellow to a different colour. Mixing white to a colour is called a tint and mixing black to a colour is called a shade. The value of a colour depends on the the colours around it. Using a red coloured piece of plastic will help you to see the value of the colours you are using, without the colour interfering. (In the quilting world they have a tool called a Ruby Beholder for this purpose.) The FIVE Design Elements are: Colour, Line, Texture, Shape and Value.

THE impact from the release of foxes in this country by early European settlers has been profound. The canine pests have decimated or even made extinct numerous populations of small animal and bird species. Now it seems foxes are on the run in Tasmania and could pose a threat to the island's abundant native wildlife, according to a new study which said DNA tests on animal droppings have proved foxes exist in small numbers on the island. Various issues bombard us from the pages and screens of different media outlets: global warming, carbon taxes, and coal seam gas for example, with in varying degrees of crisis calls. A report published in the British Ecological Society's Journal of Applied Ecology said foxes could be a serious threat to a pristine Tasmanian environment as the previous extinction wave was to Australia's mainland fauna. Yet few if any people want to face up to this issue. Farmers are encouraged to bait as part of strategies to increase numbers of lambs and small programs are run by Livestock Health and Pest Authorities in state forests and reserves. Anyone driving around the region early in the morning or late in the evening will see large numbers of foxes - cubs and adults along roadsides scrounging for a feed on roadkill. Increasing populations of rabbits will help sustain the population of foxes. Something needs to be done, but alas, it seems few people seem to be engaged in this important conservation issue.

Robert Sanders, University of California at Berkeley This article describes a permafrost subglacial lake discovered beneath Antarctica. The lake offers scientists a chance to test their sterile drilling techniques before exploring elsewhere in search of exotic microbes. Techniques that avoid contaminating a drill site with microbes, suggests the author, would prove useful for future drilling into Mars' polar caps in search of life.

Hyperkalemia Topic Guide Hyperkalemia (High Blood Potassium): Hyperkalemia is high potassium in the blood. Causes of hyperkalemia include diseases of the kidneys or adrenal glands, or some medications. Symptoms including muscle weakness, fatigue, tingling, or nausea may not appear until levels of potassium are extremely high. Treatment depends on the severity of symptoms. Kidney Disease Twenty percent of people over the age of 20 years will develop chronic kidney disease in their lifetime. Chronic kidney disease causes are diseases of the kidney(s), diabetes, uncontrolled high blood pressure, Glomerulonephritis, polycystic disease, medications, and other conditions. Symptoms include: fatigue, nausea and vomiting, edema, itching, easy bruising, anemia, headaches, insomnia, restless leg syndrome, chest pain, and more. Treatment generally involves dialysis, or kidney transplantation depending on the condition of the patient and kidney(s).

This video segment adapted from NOVA scienceNOW examines a developing theory that might explain a 250-million-year-old "murder mystery." While several possible causes have been considered for the mass extinction that occurred at the end of the Permian period, the scientists featured in the video think a chain of events, beginning with massive volcanic eruptions, might have made Earth uninhabitable for a significant number of terrestrial and marine organisms. According to their theory, these eruptions released gases that warmed both the atmosphere and the oceans. This warming in turn created ideal conditions for killer bacteria to poison the environment.

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2011 August 19 Explanation: In this remarkable infrared skyscape of interstellar clouds adrift in the high flying constellation Cygnus, the eye is drawn to the Cocoon Nebula. Also known as IC5146, the dusty star forming region is shown in blue hues in the Herschel Space Observatory false color image, at wavelengths more than 100 times longer than visible red light. And while visible light images show the Cocoon nebula at the end of long dark nebula Barnard 168, Hershel's infrared view finds the cosmic Cocoon punctuating a trail of filamentary clouds of glowing dust. The filaments have widths that suggest they are formed as shockwaves from exploding stars travel through the medium, sweeping up and compressing the interstellar dust and gas. Herschel data also indicate stars are forming along the dusty filaments. The Cocoon Nebula itself is about 15 light-years wide and 4,000 light-years away.

Hematopathology is the study of diseases of the cells that make up our blood. These cells originate in the bone marrow and become: - White blood cells - Red blood cells White blood cells are present in many important structures of the body, like lymph nodes, and are major components of the immune system. When disease invades, the body sends these cells to fight bacteria and viruses by producing antibodies against the infection. Blood cells can occasionally become abnormal; in some cases, abnormal blood cells give rise to cancers such as leukemia. The Role of the Hematopathologist Hematopathologists are specially trained to diagnose diseases of the blood cells. They use specialized tests such as flow cytometry studies and immunohistochemistry. The hematopathologist uses the results of these tests to diagnose infections and diseases of the blood, lymph nodes and bone marrow. Learn more about hematopathology from the Department of Pathology.

New Zealand - Topography Less than one-fourth of the land surface of New Zealand lies below the 200-m (656-ft) contour. The mountain ranges in the North Island do not exceed 1,800 m (6,000 ft) in height, with the exception of the volcanic peaks of Egmont, or Taranaki (2,518 m/8,261 ft), Ruapehu (2,797 m/9,176 ft), Ngauruhoe (2,290 m/7,513 ft), and Tongariro (1,968 m/6,457 ft), the last three of which are still active. This volcanic system gives rise to many hot springs and geysers. The South Island is significantly more mountainous than the North Island, but is without recent volcanic activity. The Southern Alps, running almost the entire length of the South Island from north to south, contain 19 peaks of 3,000 m (9,800 ft) or above, of which the highest is Mt. Cook or Aorangi, 3,764 m (12,349 ft). There are also several glaciers in the Southern Alps, the largest being the Tasman Glacier, 29 km (18 mi) long and 1 km (0.6 mi) wide. The rivers are mostly swift-flowing and shallow, few of them navigable. There are many lakes, those in the South Island being particularly noted for their magnificent mountain scenery.

Generally, black soil is found in the central, western and southern states of India. According Britannica, black soil is found 28 Indian states including: isolated parts of Ghat, the Malabar Coastal plains, Ratnagiri of Maharashtra and certain regions of Andhra Pradesh, Tamil Nadu, Karnataka, Meghalaya and West Bengal. Black soil also is found in some non-traditional areas throughout India.Continue Reading Black soil, also referred to as black cotton soil or regur, covers about one-third of the Deccan peninsula. Approximately 76 million hectares of the central, western and southern states of India are covered with the soil. However, Maharashtra, Madhya Prades and Gujarat have the largest share of the soil. Black soil is dark, as its name suggests, and fertile with a clay-like consistency. It holds moisture well, becoming hard in dry conditions and sticky in wet conditions. The soil is composed of less than 30 percent clay, slickensides or wedge-shaped peds and cracks that open and close periodically. In places with consistent rain, black soil is commonly used for growing millet, cotton, soybean, sorghum and pigeon pea. When the soil is irrigated, black soil is used to cultivate other crops such as sugar cane, wheat, tobacco and citrus crops. The soil can also be used as a building material.Learn more about South Asia

Battle of Maipú, painted in 1837 The Battle of Maipú defined Chilean independence of Spanish subjugation. The battle was fought in the Valley of Maipú, near Santiago, Chile, on April 5 1818, between South American rebels and "Realistic Spanish" during the Chilean War of Independence. The battle of Maipu, April 5th 1818 Chilean independence were supported by Jose de San Martin to destroy the Spanish forces led by General Mariano Osorio and complete the heart of Chilean independence. Portrait of Bernardo O'Higgins by José Gil de Castro In 1817, the Argentine General José de San Martín crossed the Andes and defeated the Spanish troops in the battles of Chacabuco, Chalchuapa and then invaded the city of Santiago de Chile. The success of both generals led to continue the liberation of South American territories up to release his Spanish Peru dependence. "The Maipú Hug" by painter Pedro Subercaseaux, in which they appear on their horses and Chile and Argentina flags, José de San Martín and Bernardo O'Higgins.

As would be expected at this northern latitude, herpetofauna (reptiles and amphibians) are not numerous. Only five reptile species are confirmed to exist within Pictured Rocks National Lakeshore. Encounters with snakes are rare, and a hiker might be lucky enough to get only a quick glimpse of an eastern garter or northern red-bellied snake before it slips off the trail into dense vegetation. These two species, along with the smooth green snake, are the only snakes confirmed at the lakeshore, although western fox snake, northern water snake, and northern ringneck snake are likely to live here as well. There are no poisonous snakes in the park. Eastern garters are the largest snakes at Pictured Rocks, occasionally growing to a length of three feet or more. They are also the first snakes to come out of hiberation in spring and have been seen moving over snow patches in April searching for early spring insects and worms. Garter snakes are generally non-aggressive but they often emit a foul, musky smell from glands near the tail when threatened. Only two species of turtles have been found in the park: western painted turtle and eastern snapping turtle. Painted turtles may be visible sunning themselves on logs in inland lakes or near the shore. As their name implies, painted turtles are colorful, with their lower shell (plastron) displaying red and yellow patterns. They also have red, orange, and yellow stripes on their neck and legs. Snapping turtles can become quite large, weighing up to 30 pounds. Their upper shell (carapace) can be more than 15 inches long. Snappers rarely bask in the sun on land as most other turtles do, but may bask on the water surface. They are almost entirely aquatic, preferring lakes, ponds, slow-moving rivers, and marshes with muddy bottoms and lots of vegetation. On a rare occasion one may venture into Lake Superior. Only the females come on land during breeding season in search of suitable nesting habitat. They dig shallow nests in well-drained sandy soils where they deposit as many as 100 eggs (20 to 40 average). Snapping turtles commonly nest along Sand Point Road from May through July. After hatching, the young turtles head for the ponds and marshes east of the road. Keep an eye out when driving for snapping turtles crossing the road. Do not disturb nesting turtles or nest sites, and observe all designated closure zones.

NASA is in full swing preparing for the colonization of the red planet. The idea is to colonize Mars, humanity has for a long time. A lot has been done in this way. Working in this direction, not only NASA, but private companies such as SpaceX, headed by Elon Musk. For successful colonization, NASA has studied the radiation level with the help of Curiosity Rover. This will help to protect future astronauts. Also in 2020, scientists plan to send another unit for a more detailed study of the Martian resources, including the possibility of obtaining oxygen. The problem of the lack of oxygen is one of the most important on the path to a successful project. As an alternative solution to consider the use of bio-domes with microorganisms inside that will remove from the soil the nitrogen and remove the oxygen. Thus, on the tiny microbes will bear the great responsibility. At issue is also the availability of building materials on Mars. Scientists from Bradley University organized a special prize of $ 2 million, to which can whoever figure out how to convert Martian soil into a durable building material. As variant is also considered printing the necessary parts of dwellings on a 3D printer. Do not forget the scientists and the need of settlers to the colony in food. They are conducting experiments with potatoes in search of the most hardy varieties for complex Martian soil.

Third graders just learned completed a project that combined Math and Art! We began by looking at the art of Pop artist, Romero Britto, and his Pyramid Project in London. Students sketched four sides (faces) for their own pyramids, incorporating Egyptian symbols into each side as Britto did in his art. They also combined patterns and either warm or cool colors with black outlines. Finally, we cut out our pyramid patterns and assembled them. We were able to count and discuss vertices, edges, and faces in our 3D shapes-a concept third grade teachers asked me to incorporate!

Did I mention that these cards grew from the fact that I was pretty sure that many of my high-achieving students could solve the equations for multiplying fractions, but I was not sure that they truly understood what they were doing or why you would multiply a fraction by a fraction or a fraction by a whole number. With these cards, students were exposed to examples, had to represent what it meant on a picture, and had to create their own situations/word problems. I included 16 task cards each for multiplying fractions times a whole number and fractions times a fraction. 8 of the cards in each set focus on modeling a word problem and 8 of the cards focus on writing a word problem and equation to represent a model. I also made a version of the task cards that are one to a page so that you can show them on the smart board. This is actually how I used the problems to launch the lesson (students had their recording sheets and I displayed the cards on the board so that we could "math talk" about what we were thinking and share our representations.) After day 1, students worked on the task cards independently. These task cards fit 4th and 5th grade Common Core standards for fractions. Have you checked out my other recent math posts? Here's a run-down: Fractions Fractions Fractions (differentiation strategies and subtracting fractions with regrouping)Division with Fractional Parts (Multistep and CHALLENGING!)

After today's discussion in class, I realized that teachers should not overwhelm their students with technology nor should they be too dependent on technology within the classroom. However, I believe that technology can be an extremely useful learning tool. It provides new ways for students to visualize the subject matter, especially when dealing with different dimensions, graphs, and shapes. By using technology, the teacher can reach out to more of his/her students with the incorporation of different learning styles. For example, when finding the volume of a cylinder, some students may be able to memorize the equation without ever visualizing the actual object. However, for the spatial learners, they may need to see that you first find the area of one of the bases and then multiply it by the height. These forms of technology will allow teachers to gear their instruction more accurately towards the specific learning goal by acknowledging each student's learning style. When reading Pete Rubba's thoughts about online courses vs. face-to-face teaching, I found it hard to believe that face-to-face teaching would dwindle away so quickly. I feel that face-to-face interaction is something that cannot be replaced. I understand that Rubba was trying to stress how important technology is in education, but I feel he was to extreme on his assumption. I agree best with Bob McCollum and Kyle Peck's beliefs on the matter. When it comes to teaching a math courses, I believe that one of the most important aspects is relating the methods/concepts to the each student's learning style. It is important to go into further instruction with an individual student if they are having a specific issue. Unfortunately, students do not have the luxury of being explained in a different way when taking an online course. I found it interesting to read about how technology has progressed over time and how it affects our limitations as learners. Technology provides simplified ways to approach complex material. Since technology has helped math progress tremendously over the years, I find it very important to use it within the classroom, but I know not to rely on it. When making those lessons using technology, it is important to know the capability of your students so it is not too simple or too complicated. Therefore, you can maximize each student's learning experience.

The twin paradox in physics is a thought experiment in special relativity. It involves identical twins, one of whom makes a journey into space in a high-speed rocket and returns home to find that the twin who remained on Earth has aged more. The paradox depends upon the unspoken idea that the passage of time is the same in all circumstances. But this is not correct. Time is relative and the speed of light through a vacuum is the only constant. And the universe is relativistic, not Newtonian. Every single test which has been made has shown this.

Yes, writing more does lead to better reading comprehension. Research proves it. But why? The authors of The Reading – Writing Connection (2010) suggest many reasons: - Both reading and writing are forms of communication. When writers create a text, little light bulbs go off as they think about their audience and what that audience needs in order to understand and want to continue reading their texts. Students write, but at the same time they act as readers, their own first audience. - Writers think about composing skills when they read the texts of other writers. Why does the author use that vocabulary word? Why does the author have a first person narrator? How does the author identify characters through their dialog? Does an autobiography have to start with a birth? Does a story need to go in chronological order.? If not, how can ideas be arranged? How do other authors do this? They read to find out. - How do other writers connect sentence ideas or paragraphs? How do they explain things—with figures of speech or with examples? How do other authors make a difficult idea clear? Do they depend on charts, graphs or maps? When writers read, they are not merely enjoying or gaining information. They are also aware that what they are reading was written by someone who had to make writing decisions, the same kind of writing decisions they have to make. By thinking about those decisions, student writers understand better what they are reading.

开始时间: 待定 持续时间: Unknown We all have to breathe to live. But the air we breathe is polluted both outdoors and indoors. Each year, this pollution costs 7 million lives across the globe – and a lot of suffering. 1 in 8 deaths is due to air pollution. This course will provide you with an introduction to the most recent research in the field of health effects of air pollution as well as a broader understanding of sources and spread of air pollution and what we should do about it. What is air pollution? What are the sources? How and where are we exposed outdoors and indoors? What happens in the body? Which diseases are the result? Who are the most vulnerable? How can we assess the effects of air pollution? And what should we do to reach the Sustainable Development Goal to “substantially reduce the number of deaths and illnesses from hazardous chemicals and air, water and soil pollution”? These are some of the important questions we will address in the course. During the course you will meet researchers and experts from the University of Copenhagen and the Technical University of Denmark. They work with different aspects of air pollution and health: toxicology, exposure assessment, epidemiology, engineering and health impact assessment. It is a global responsibility to combat the health impacts of air pollution, and this fight can only be won through new knowledge and global collaboration. We hope you will join us in the course and equip yourself to take part in this global and individual health challenge.

First page Back Continue Last page Overview Text We have mentioned that a microcomputer includes three fundamental components, Central Processing Unit (CPU), Main Memory (MM), and Input/Output (I/O). These three components are connected by sets of parallel electric conductors (wires), called buses. A bus is a set of parallel connections between components. There are three types of buses in a microcomputer: address, data, and control. The address bus is used mainly by the microprocessor to indicate which particular address in main memory or which I/O port needs to be accessed. The data bus is used for retrieving information from main memory or I/O for the microprocessor, or for storing the information from the microprocessor to memory or I/O. The control bus is responsible for transmitting task commands such as “read” and “write” to the memory and I/O components and for receiving corresponding responses from them.

insights from Open Data or your own There is a treasure trove of insights out there just waiting to be discovered. These nuggets of knowledge are scattered across Open Data portals and buried in files. After digging them up, they can be processed, polished and displayed. Learn data science skills and techniques to understand how insights are discovered While the approach to each project will vary case by case, the data science process will typically involve most (if not all) of the following stages: Raw data can come in a variety of tabular, layered and geographical formats. It can be collected from a wide range of sources including Open Data portals, webpages and live streams. Like the real world, real data can be messy. For example, it can contain gaps, typos and duplication. Cleaning produces a dataset that is consistent, complete and representative. All datasets are different. By gaining familiarity with each one, relevant variables can be identified. Relationships and trends can be flagged for further investigation or candidates for modelling. The data must be in the right format for the next stages. Achieving this may involve selecting and combining relevant variables, filtering values and ordering them. Datasets can also be joined for a broader analysis. Algorithms can process the refined data, quantifying trends and patterns to generate insights or make predictions. Cloud computing offers the scalability to churn through virtually limitless data. A picture can be worth a thousand words or a million data points. Clear and, where appropriate, interactive visualizations allow complexity to be communicated in ways that audiences can understand. To be notified when new tools and case studies are released: Do you have data but don't know what to do with it? Do you have questions but are unsure how to answer them?

“Nutrient pollution” is caused by excess nitrogen and phosphorus entering our waterways. The excess nutrients can cause algae blooms, clouding the water, which decrease the sunlight water plants need to grow and produce oxygen. As a result oxygen in the water decreases, impacting the fish and other creatures which need the oxygen to survive. As the algae dies and sinks to the bottom it decays in a process which also consumes oxygen. Over the last 50 years the amount of nitrogen and phosphorus entering our waterways in the U.S. has increased dramatically. It has the potential to become one of America’s costliest and most challenging environmental problem. Nutrient pollution threatens our waters used for drinking, fishing, swimming and other recreation. It can cause health issues for people and wildlife. Recreation, tourism, jobs and our economy depend on clean water.

Usually Ships in 1-5 Days (This item cannot be returned.) WHY THIS EDITION IS SPECIAL? Inside you can find a J.A. Hammerton work about Mary Shelley's life and her process of writing Frankenstein. J.A. Hammerton was "the most successful creator of large-scale works of reference that Britain has known" Mary Shelley began writing Frankenstein when she was only eighteen. At once a Gothic thriller, a passionate romance, and a cautionary tale about the dangers of science, Frankenstein tells the story of committed science student Victor Frankenstein. Obsessed with discovering the cause of generation and life and bestowing animation upon lifeless matter, Frankenstein assembles a human being from stolen body parts but; upon bringing it to life, he recoils in horror at the creature's hideousness. Tormented by isolation and loneliness, the once-innocent creature turns to evil and unleashes a campaign of murderous revenge against his creator, Frankenstein.

Tularemia, also known as “Rabbit Fever”, is a potentially fatal bacterial disease caused by Francisella tularensis. People and many animals, including rodents, pets, and livestock, can get tularemia. You or your pet may get tularemia from: Bites from infected ticks or deer flies Ingesting contaminated meat or water Touching sick animals Inhaling the bacteria Infected animals may be depressed, have a fever, or refuse to eat. Infected rabbits and rodents may have a rough hair coat and huddle together strangely. Tularemia is not uncommon on the Western Slope, and there was a case of a cat with tularemia in Delta County in 2011. Symptoms in humans depend on the route of infection. If infected through the skin, a non-healing wound and swollen lymph nodes may appear. If ingested, people may experience generalized gastrointestinal illness. If inhaled, pneumonia-like symptoms may appear. If detected early, tularemia can be treated with antibiotics. To keep yourself safe, remember to avoid contact with all wild animals, wear insect repellant, and check yourself for ticks.

The Simplest Macrophage consists of only 1 cell, which is a Phagocyte. As its name says, it's the simplest macrophage that doesn't need any special settings. Simplest Macrophage can also be modified by radiation. Because it is a Macrophage, it lives in a medium-rich nutrient rate substrate.It lives in medium-low viscosity, because it needs much space and speed to move in order to search for food. Genome and Variations The basic version doesn't need any change of settings. The small variations that this organism can have that actually change something on the behavior are the Split Mass which can be lowered down to aproximately 1.53mg in a standard substrate while still being viable, which will cause the cell to split more times, which will make the variation generally weaker to harsh enviroments but larger in population. Another variation is to change the Split and Child Angles, which can improve the position of the childs, to ensure that the substrate is covered faster and more effectively. - It is the simplest organism that doesn't need any settings to configurate.

Nematodes or roundworms are almost microscopic worms – the majority of them can be beneficial as they help break down organic matter and control pests such as insects. However there is one group of nematodes which are real troublemakers – they attack and feed on the roots of plants, and if their numbers explode, the damage to a plant’s roots can kill young plants and stress older plants so they become prone to diseases. So how can we control these damaging nematodes? There are chemical solutions to fumigate your soil – unfortunately many of these are very toxic and will kill other soil inhabitants. The other method which can be effective is solarisation – in essence you dig over the soil and cover it in black plastic and then let the heat of the sun cook the soil. Again you kill nearly everything else in the soil, and it only works in hot conditions in the middle of summer. There is a biological solution however, and that is with nematode-eating fungi. There are about 300 different fungi that essentially feast on nematodes. Some destroy the nematode eggs, and others grow into the mouth of nematodes and digest them from the inside out, but the most interesting fungi are those that trap nematodes using sticky pads or lassos. Once the nematodes are stuck, they are digested by the fungi. So why do the fungi do this, and how do you encourage them in your soil? For the fungi, the nematode represent a meal of protein in the form of nitrogen. So when you use very high nitrogen-based fertilisers (especially some of the chemical fertilisers), the fungi actually switch off the nematode-killing system, because they are getting all the nitrogen they need for free. So using these types of fertilisers can actually make your nematode problem worse. It has been discovered that low levels of slower-released nitrogen provided by products such as Seamungus, Whoflungdung and even Gyganic actually stimulates the fungi to produce these nematode traps, and therefore helps to control them. Obviously adding organic matter to your soil and encouraging a diversity of microbes ensures that these nematode-eating fungi are present in the first place. So not only can these products help control nematodes in an environmentally friendly way, they also feed your soil and plants at the same time.

As the planet confronts global warming, hydrogen will become an increasingly important energy source, affecting many sectors in which Broadleaf works. Hydrogen is important because it can be environmentally friendly: - It can be produced from renewables - Energy can be extracted from hydrogen in an environmentally friendly manner: whether used for combustion or in fuel cells, its primary by-product is water, rather than the carbon dioxide that is generated by burning hydrocarbons such as natural gas, coal, crude oil, other hydrocarbon liquids or biomass. Hydrogen is described in different ways, according to the energy sources and feedstocks used to produce it and the kinds of by-products that are generated. To assist those interested in this matter of growing importance, this tutorial summarises the colour descriptions attributed to specific forms of hydrogen production and outlines some of the associated technologies. A selection of source references is provided. You can read the full tutorial here.

APRIL IS EARTH MONTH April is a month to raise environmental awareness. Did you know many researchers agree that children who play outside are happier, better at paying attention and less anxious than kids that spend more time indoors? Spending time outdoors has also been proven to help build confidence for kiddos. 5 WAYS TO TEACH KIDS ABOUT THE ENVIRONMENT - 1. Do a scavenger hunt – find different trees, plants or insects. - 2. Make art projects with things you find in nature such as leaves, twigs, flowers or pebbles. - 3. Teach children about animals – what animals can they find outside? Squirrels, rabbits, birds, dogs? - 4. Take kids to a park to pick up trash and talk about why littering hurts the environment. - 5. Simply get them in the fresh air!

Also known as “praejuramentum” or “juramentum calumniae”, this was an oath taken by both accuser and accused ahead of a trial by compurgation, such as by combat or other judicially sanctioned duels. If the accuser failed the trial, the accused went free. According to Merriam-Webster dictionary, the word, derived from Latin, was first used in this sense sometime around 1763.

Statistics is the study and manipulation of data, including gathering, reviewing, analyzing, and drawing conclusions from data. It is also a collection of quantitative (of, relating to, or involving the measurement of quantity or amount) data that can be used as evidence within research. When either writing or speaking, using appropriate statistics can help prove or disprove your point. Statistics can help provide concrete examples of a larger trend, give the basis for an important chart or graph, or make theoretical arguments tangible. This works best with statistics from reliable resources. Logically weaving statistics into your essays, papers, or speeches will strengthen your work. What can statistics do? Things You Need to Consider: The largest collector of statistics is the (US) federal government, and much of the data is available on government websites, often on the site of the agency or office (Department of Education, Office of Environmental Management, etc.) that is responsible for collecting the data. You can find statistics in many of our library databases. Search Words - try these keywords or subject terms with your topic searches to focus on statistics: Statistics - Data - Numbers - Trends - Polling - Figures - Tables - Charts - Graphs (part of above courtesy of Modesto Junior College)

An exciting new research programme lead by Scottish researchers will try to determine whether cooling the bodies of patients who have suffered brain injuries could increase their recovery and decrease long term disability. Hypothermia is something, which generally is thought to be dangerous and in some cases life threatening but work is being done to determine if inducing hypothermia in patients could actually protect their brain from further damage. A two million pound study is being carried out to investigate this. Evidence from past studies suggests that inducing hypothermia puts the body into hibernation and allows the brain to function with a reduced blood supply. Accidents at work, road traffic accidents, trips and falls frequently lead to head injuries which can result in swelling of the brain and reduced blood flow to the brain. The consequences of traumatic brain injuries can be devastating and life changing for the patient and their families and loved ones. It is estimated that in Europe each year there are around one million admissions to hospital due to a traumatic brain injury. Here’s hoping the study is a success and the outcome equates to better care and better chances for those who have suffered a brain injury and their families and loved ones.

This article needs additional citations for verification. (September 2014) Polishing is the process of creating a smooth and shiny surface by rubbing it or by applying a chemical treatment, leaving a clean surface with a significant specular reflection (still limited by the index of refraction of the material according to the Fresnel equations). In some materials (such as metals, glasses, black or transparent stones), polishing is also able to reduce diffuse reflection to minimal values. When an unpolished surface is magnified thousands of times, it usually looks like a succession of mountains and valleys. By repeated abrasion, those "mountains" are worn down until they are flat or just small "hills." The process of polishing with abrasives starts with a coarse grain size and gradually proceeds to the finer ones to efficiently flatten the surface imperfections and to obtain optimal results. The strength of polished products can be higher than their unpolished counterparts owing to the removal of stress concentrations present in the rough surface during the polishing process. These concentrations take the form of corners and other defects, which magnify the local stress beyond the inherent strength of the material.

When frost has been predicted, growers should take note of their vineyard’s growth stage so a strategy can be developed. Vineyards that have not yet begun to break may not require special attention. When green shoots are longer than six inches, soils may need to be prepped in advance of cold weather. Table 1 shows the relative susceptibility of grapevine tissue at different growth stages and critical temperatures. Table 1. Frost damage to various growth stages of grape. |Growth Stage||Critical Temperature*| |Buds with wool (eraser stage)||< 26˚F| |Shoots < 6” in length||< 31˚F| |Shoots > 6” in length||< 32˚F| *Critical temperatures are based on research under controlled environments. Vineyard characteristics (location, cultivar, etc.) may increase or decrease susceptibility to frost damage. These values should only be used as a point of reference when developing a frost protection program. In order to minimize damage caused by frost, vineyard soils should be prepared for maximum heat absorption during the day and release at night. Optimal conditions include soils that are free of vegetation, firm in texture, and moist. Moist dark soils improve their ability to absorb heat during the day and radiate it at night as ambient temperatures drop. Soil texture will also have an impact on heat absorption. Vineyards planted to sandy soils are more prone to frost damage because they lack the ability to retain water. Additional water may be needed if winter precipitation has not been adequate to maintain soil moisture. Prior to a predicted frost, the goal should be a uniformly distribute irrigation, that allows for maximum heat absorption.

It is difficult to characterize the hazard posed by meteoroids and debris to the ISS because most of the meteoroids and debris that could harm the space station are small, dark, and fast moving and thus difficult to detect from the Earth. Moreover, the meteoroid and debris environment in the ISS orbit can vary greatly, depending on the state of the solar cycle and the number and severity of recent breakups of orbiting objects. Adequately protecting the ISS from this environment is also challenging because of the uncertainty of the threat and the difficulty of accurately simulating the effects of high-speed meteoroid and debris impacts. The team building the ISS has developed a strategy to manage the hazard posed by meteoroids and debris to the ISS. To support this strategy, the team has developed models that predict the flux of meteoroids and debris in the ISS orbit. The ISS program uses these models to determine the chances that the station will collide with meteoroids and debris of various sizes. The program plans to reduce the hazard by: (1) shielding elements of the ISS to protect them from impacts with the smallest meteoroids and debris, (2) moving the ISS out of the path of the rare pieces of debris large enough to be tracked by ground-based sensors, and (3) implementing design features and operational procedures to minimize the

Graphs give students a great tool for visualizing criteria. Earlier we explored how to analyzing characters using graphs on a coordinate plane. In this article, we’ll be building on graphs as a character analysis tool. The line graph is perfect for showing a character’s change over time. Here’s Katniss’ confidence as it changed across The Hunger Games. And here’s the ethics of Han Solo’s actions across Star Wars, ranked from selfishness to selflessness. Imagine looking at historical figures across time or comparing multiple characters on the same graph. The criteria could include: In another article, we helped students form strong opinions of the “best” life cycle amongst frogs, butterflies, and mice. A bar graph can help students visualize the categories they’re using to form an opinion. We used the following categories: - Safety of young - Competition for food with adults - Parental involvement In each category, students rank the life cycles on a scale of 1 – 4. Here are my results: We could use the bar graph to form opinions in social studies, as well. If students are choosing Sparta or Athens as the best, they can compare strength, freedom, and government: And bar graphs could also apply to characters’ traits, as seen here with three members of The Avengers: Of course, if you change the criteria, the graph might change drastically, emphasizing how different criteria strongly affects the final decision: Naturally, you’d expect an explanation along with these visual representations: Sparta ranks the highest in strength because of their legendary army. Athens, although not as strong, is no slouch thanks to their powerful navy. Sparta and Athens both rank in the middle in terms of freedom. Athens held elections, but denied women and slaves rights. Spartan women had more rights, but did not hold elections. Finally, Athens’ democratic government beats Sparta’s kings. Have more ideas for graphing beyond math?

An invention is something that is made by human beings and that did not exist in the world before. Inventions include items, devices, processes, materials, machines, and toys from AstroTurf® to zippers. A discovery is something that existed before, but was not yet known or “discovered”; for example, the concept of black holes in outer space. Inventions and discoveries usually come about by bringing together existing technologies in a new way, and they may take centuries to take shape. They usually are created in response to a specific human need, such as a medicine to heal sickness; as a result of the creator’s desire to complete a task more efficiently or effectively, such as a tool or machine; or even by accident, such as the Slinky. Sometimes just one person makes the discovery or invention; other times the end result is the product of a team effort. Sometimes different people have made the same invention independently at the same time. In very rare cases different people have made the same invention on the same day.

Drawn to sports by her recovery from childhood illness, Senda Berenson became known as the “Mother of Women’s Basketball.” Senda Berenson’s ill health meant she had to be tutored at home and later drop out of the Boston Conservatory of Music. In an attempt to regain her strength, she enrolled in the Boston Normal School of Gymnastics, training to become a gymnastics coach. She began teaching at Smith College at twenty-three, and a year later discovered a new game called “Basket Ball” that she decided to adapt for women players, despite the fact that, at the time, women only played individual sports because team sports were thought too dangerous. She refereed the first official game of women’s basketball in 1893, with Smith freshmen battling against the sophomores. Within two years, there were hundreds of women’s basketball teams, and the success of the game opened the door for other women’s sports. Berenson developed the official rulebook for women’s college basketball, and many of the rules she created remained in force for the next seventy years. How to cite this page Jewish Women's Archive.

Objective: Before the German occupation, Alicia and other Jews were able to practice their religious beliefs in peace. This allowed closely knit Jewish communities to develop in Poland and much of Eastern Europe. In many countries, people are not always allowed to practice their religious beliefs. There beliefs are repressed and this may cause oppression and unrest. 1) 1.Choose another time in history where a group of people were forced to quit their religious beliefs. How did these people overcome their oppressors or were they never able to? 2.Part I: The Jews have been oppressed many times throughout history. Create a timeline that explains the oppression that faced the Jews. Part II: Go back through your timeline and pick one event that stood out to you. Write a three page historical summary that describes the event. 3.Journal Entry: What does it mean to be close to your community...

Confederate Military History of Missouri:As a border state, Missouri was coveted by both the Union and the Confederacy at the beginning of the Civil War. Missourians took sides, with politicians trying to either keep Missouri in the Union or trying to secede and join the ranks of the Confederate States. In the end, the Show Me State remained with the Union but was given an honorary status in the Confederacy, even being represented with a star on the Confederate flag. Fighting soon erupted in the state, causing Missourian to fight Missourian-a sort of civil war within a civil war. The largest battle fought in Missouri was the Battle of Wilson's Creek, August 10, 1861, where Union forces under Nathaniel Lyon and Franz Sigel attacked Confederate forces under Ben McCulloch in the early-morning hours. While Wilson's Creek allowed the Confederates to retain control of the southwestern portion of the state, they soon retreated to Arkansas. While in Arkansas, Confederate forces made forays and raids into Missouri. Missouri troops were brigaded together and fought in both the Trans-Mississippi and Western theaters. Battles included Pea Ridge, Arkansas; Corinth, Iuka, Big Black River, and Vicksburg, Mississippi; Pleasant Hill and Jenkins' Ferry, Arkansas; New Hope Church and Allatoona, Georgia; and Franklin and Nashville, Tennessee. Major battles in Missouri during the war include Belmont, Carthage, Independence, Lexington, Little Blue River, Newtonia, Springfield, and Wilson's Creek. The following men from Missouri became generals in the Confederate Army: John S. Bowen, John B. Clark, Jr., Francis Marion Cockrell, Daniel, M. Frost, Martin E. Green, John Sappington Marmaduke, Mosby Monroe Parson, Sterling Price, Joseph O. Shelby, andJohn G. Walker. The end of the war found most of the Missourians in Alabama, where they were surrendered and paroled, eventually making their way home.

Plot. A plot is a series of events related to a central conflict, or struggle. A plot includes the introduction of a conflict, its development, and its resolution. In a short story, the events in the plot usually lead from one to the next. Review the parts of a plot on page 512. Try to identify the climax as you read All Summer in a Day. Science Fiction. Science fiction is imaginative literature based on scientific principles, discoveries, or laws. Science fiction writers often suspend or alter elements of reality to teach the reader something about our planet or ourselves. As you read, compare Bradburys picture of Venus with what scientists actually know about that planet (as shown in Readers Resource). Science Connection. Venus is the second planet from the Sun and the second brightest object in our nighttime sky. (The moon is the brightest.) Often called Earths sister planet, Venus is similar to Earth in size and mass. Venus is covered by a nine-mile-thick layer of clouds, is much too hot for water to form, and has an atmosphere made up mostly of carbon dioxide. Life as we know it cannot exist under such conditions. Venuss heavy clouds trap great amounts of solar heat as the result of what is known as the greenhouse effect. In fact, Venus is so hot that its rocks glow red with heat. Biology Connection. You may have heard about the wintertime blues or noticed that some people seem happier and more energetic in spring, summer, and early fall than they do in winter. All people react to seasonal changes to some degree. For some people, however, winter and its decreased sunlight can cause serious emotional problems. People affected by Seasonal Affective Disorder, or SAD, feel very depressed and tired in winter. They often retreat from family and friends and have trouble concentrating. Doctors have found that controlled exposure to bright light can make people with SAD happier and more productive. Similes and Metaphors. A simile is a comparison using like or as. A metaphor is a figure of speech in which one thing is spoken or written about as if it were another. Look for similes and metaphors as you read All Summer in a Day. Imagine that you are describing the sun to someone who has never seen or felt it before. In what way would you describe the sun? To what could you compare it?

What is a sinus infection? How is it different from the common cold? Let’s look at answering these two questions. A sinus infection can be defined as inflammation, or swelling, of the tissues lining the sinuses. Normally, the sinuses are filled with air. However, when they become blocked they can fill with fluid allowing germs to grow resulting in an infection. Blockage of sinus cavities can occur due to swelling from allergies or the common cold, nasal polyps or a deviated septum. About 37 million Americans suffer from at least one episode of sinusitis each year. In children, some common environmental factors which can contribute to the incidence of sinusitis include exposure to other sick children at day care or school, the use of pacifiers, bottle drinking while lying on one’s back, and second hand smoke. In adults, smoking and allergies are the main contributors to developing a sinus infection. Some of the primary symptoms of acute sinusitis include: - Facial pain/pressure - Nasal stuffiness - Nasal discharge - Loss of smell - Bad breath - Dental pain Acute sinusitis may be diagnosed when a person has two or more symptoms and/or the presence of thick, green, or yellow nasal discharge. Treatment for sinusitis depends on the severity. Usually antibiotics are given for 10 to 14 days. In addition, warm moist air may alleviate sinus congestion such as from a vaporizer or inhaling steam from a pan of boiling water (removed from heat). Warm compresses can be used to relieve pain in the nose and sinuses. Saline nose drops are also safe for home use. Use of nonprescription decongestants or nasal sprays might be effective in controlling symptoms; however, they should not be used beyond their recommended use. Injectable or oral steroids may also be prescribed. If you think you may have a sinus infection, give us a call. At Poinsett Family Practice it is our desire to provide you with the best possible care.

Researchers at The Scripps Research Institute have found a temperature-sensing protein within immune cells that, when tripped, allows calcium to pour in and activate an immune response. This process can occur as temperature rises, such as during a fever, or when it falls—such as when immune cells are “called” from the body’s warm interior to a site of injury on cooler skin. The study, recently published online ahead of print by Nature Chemical Biology, is the first to find such a sensor in immune cells—specifically, in the T lymphocytes that play a central role in activation of killer immune cells. The protein, STIM1, previously known as an endoplasmic reticulum (ER) calcium sensor, had been thought to be important in immune function, and now the scientists show it is also a temperature sensor. “Temperature has a profound effect on all biological processes including immune responses, but surprisingly little is known about molecules in immune cells that sense temperature sifts,” said the study’s principal investigator, Scripps Research Professor Ardem Patapoutian. “Here we show that STIM1 senses temperature and has a profound impact on immune cells.”

1800 - 1900 A.D.| Invention of the punch card Invented by Joseph Marie Jacquard, an engineer and architect in Lyon, France, punch cards laid the ground for automatic information processing. For the first time information was stored in binary format on perforated cardboard cards. In 1890 Hermann Hollerith used Joseph-Marie Jacquard's punch card technology to process statistical data collected during the US census in 1890, thus speeding up US census data analysis from eight to three years. Hollerith's application of Jacquard's invention was used for programming computers and data processing until electronic data processing was introduced in the 1960's. - As with writing and calculating, administrative applications account for the beginning of modern automatic data processing. Paper tapes are a medium similar to Jacquard's punch cards. In 1857 Sir Charles Wheatstone used them for the preparation, storage, and transmission of data for the first time. Through paper tapes telegraph messages could be stored, prepared off-line and sent ten times quicker (up to 400 words per minute). Later similar paper tapes were used for programming computers. Invention of the electrical telegraph With Samuel Thomas Soemmering's invention of the electrical telegraph the telegraphic transmission of messages was no longer tied to visibility, as it was the case with smoke and light signals networks. Economical and reliable, the electric telegraph became the state-of-the-art communication system for fast data transmissions, even over long distances. Click here for an image of Soemmering's electric telegraph. Invention of the telephone The telephone was not invented by Alexander Graham Bell, as is widely held, but by Philipp Reiss, a German teacher. When he demonstrated his invention to important German professors in 1861, it was not enthusiastically greeted. Because of this dismissal, he was not given any financial support for further development. And here Bell comes in: In 1876 he successfully filed a patent for the telephone. Soon afterwards he established the first telephone company.

Evidence of song learning among bellbirds is bolstered by data from a captive-reared Bare-throated Bellbird in Brazil. By December 2000 through February 2002, when this bellbird was at least 6-8 years old, he no longer sang the blackbird whistles or prrrrs, only the Quoks of bellbirds. The behavioral evidence for song learning among these suboscine bellbirds is extensive. Second, many young Three-wattled Bellbirds, as well as a few adults, are completely bilingual, singing the entire set of both Monteverde and Talamanca songs. A fourth line of evidence consistent with song learning is that young male bellbirds "babble," taking 6 years or more to perfect their songs, just as they take 6 years or more to acquire their adult plumage. Our study extends the field observations of Barbara Snow (1970, 1973, 1977), who first suggested that suboscine bellbirds may learn their songs. The most parsimonious conclusion is that vocal learning has arisen independently in bellbirds, rather than their having retained this trait from some shared, common ancestor among the song-learning oscines. The origin of vocal learning in bellbirds is either the third or fourth well-documented, evolutionarily independent origin of vocal learning in birds. We cannot be sure how vocal learning evolved among Procnias suboscine bellbirds in general, or why Three-wattled Bellbirds continually relearn their songs to track population changes, but we suspect that strong sexual selection has played a role, as suggested by Aoki (1989). Habitat linkages and the conservation of tropical biodiversity as indicated by seasonal migrations of Three-wattled Bellbirds. A possible fourth dialect of the Three-wattled Bellbird may occur on the Azuero Peninsula of Panama (Hamilton et al.

Connecticut has six trash-to-energy plants. Each year, they process more than two million tons of municipal solid waste – that’s 82 percent of the state’s post-recycled trash. They turn that trash into 194 megawatts of clean, renewable power – enough electricity to power almost 300,000 homes. Electricity generated at trash-to-energy plants is a Class II renewable power source in Connecticut. The state’s Renewable Portfolio Standard mandates that 6 percent of all electricity sold in Connecticut be generated by renewable sources. We may run out of fossil fuels such as oil, gas and coal, but humans never stop producing trash. Trash-to-energy plants are equipped with emissions controls that are superior to other waste combustion and coal-fired power plants. An analysis using U.S. Environmental Protection Agency models determined that trash-to-energy also avoids 36 million tons of greenhouse gas emissions each year. The U.S. EPA praised the outstanding performance of the nation’s trash-to-energy facilities by stating that “these plants produce 2,800 megawatts of electricity with less environmental impact than almost any other source of electricity.” In fact, trash-to-energy offers an additional environmental benefit – preservation of precious landfill space. Trash-to-energy reduces by about 90 percent the volume of waste that must go into a landfill, and the residue is tested and meets strict EPA standards for landfilling. The Connecticut Resources Recovery Authority oversees operation of trash-to-energy plants in Hartford,and Preston. About three of every five Connecticut municipalities send their trash to a CRRA plant. In 2004 CRRA’s trash-to-energy plants generated 1.1 billion kilowatt hours of Class II green power. That’s enough to supply 119,000 homes. The Connecticut Department of Environmental Protection reports that the state has very few out-of-state disposal options and stiff competition from neighboring states that also need places to dispose of their trash. Connecticut’s trash-to-energy plants operate at full capacity, and the state sends more than 200,000 tons of waste to out-of-state landfills each year. Protecting existing disposal capacity and planning for more disposal capacity will become an increasingly important issue for local and state officials. Trash-to-energy makes sense for Connecticut.

A spider’s web is an efficient passive trap used to catch insects. The insects unwittingly blunder into the trap and remain stuck in the silk threads until the spider comes to paralyze and eat them. Most webs are spun by species in the Araneidae family. Not all of the threads in a web are sticky. The threads that form its rays are not. Only the silk that forms the spiral is sticky. The vibrations created by the insect as it tries to escape from the web alert the spider to its presence. The spider has special anti-adhesive hairs on its legs and travels only along the non-sticky threads so that it doesn’t get caught in its own trap. Some spiders produce silk threads that are made of the most resistant material known on the planet. These threads are stronger than steel of the same thickness! Their elasticity is also remarkable – they can be stretched to two times their length without breaking.

F Scott Fitzgerald, a novelist, coined the phrase “The Jazz Age” to closely describe the exciting and flamboyant culture of the 1920’s. The age takes its name from jazz music, which saw a tremendous surge in popularity among many segments of society. This exciting culture centred on the media, music, arts, literature and fashion. During the 1920’s the media was able to develop so steadily and substantially because of the growing motion picture industry, and media such as films and magazines emerged as a primary area of graphic design. The arts of the 1920’s influenced the culture drastically and the jazz lifestyle appealed to many. New art forms were affecting the fashion and the architecture of the United States during this time. The styles most associated with the jazz age are striking, bold, geometric and abstract. Many artists drew inspiration from avant-garde art movements such as Cubism, Futurism and Vorticism. The use of such styles in a growing commercial arts industry introduced elements of modern art to a much wider public than would be possible for a contemporary gallery. In the 1920s, jazz became more than just a musical style. Jazz was style.

John Cabot's father's name is Giulio Caboto, but there are no records stating his mother's name. His father was a respected spice merchant. The family moved to Venice from Genoa when John Cabot was only 11 years old, where John learnt navigation and sailing from Italian merchants and seamen.Continue Reading John Cabot was the second European explorer to reach North America, specifically Canada, after Christopher Columbus. He was granted permission by King Henry VII in 1497 to sail north of Europe. Although he was searching for Asia, he actually landed in Canada 50 days into his voyage. When he returned, he was granted a pension of 20 pounds, in addition to a 10 pound reward from King Henry VII. A year later, in 1498, he again set sail to North America. John Cabot is known for paving the way for England's entry into North America and claiming the land for the Crown.Learn more about Renaissance & Reformation

An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction that can produce free radicals, leading to chain reactions that may damage cells. Antioxidants such as thiols or ascorbic acid (vitamin C) terminate these chain reactions. To balance the oxidative state, plants and animals maintain complex systems of overlapping antioxidants, such as glutathione and enzymes (e.g., catalase and superoxide dismutase) produced internally or the dietary antioxidants, vitamin A, vitamin C and vitamin E. Diets containing foods rich in antioxidant vitamins or antioxidant dietary supplements do not improve health nor are they effective in preventing diseases. Randomized clinical trials including supplements of beta-carotene, vitamin A and vitamin E singly or in different combinations found no effect on mortality rate and cancer risk, or may even increase cancer risk. Supplementation with selenium or vitamin E does not reduce the risk of cardiovascular disease. Oxidative stress can be considered as either a cause or consequence of some diseases, an area of research stimulating drug development for antioxidant compounds for use as potential therapies Adapted from Wikipedia, the free encyclopedia.

'''Asa Gray''' (November 18, 1810 – January 30, 1888) is considered the most important American botany|botanist of the 19thcentury. His ''Darwiniana '' was considered an important explanation of how religion and science were not necessarily mutually exclusive. Gray was adamant that a genetic connection must exist between all members of a species. He was also strongly opposed to the ideas of hybridization within one generation and special creation in the sense of its not allowing for evolution, as he felt theistic evolution|evolution was guided by a Creator. As a professor of botany at Harvard University for several decades, Gray regularly visited, and corresponded with, many of the leading natural scientists of the era, including Charles Darwin , who held great regard for him. Gray made several trips to Europe to collaborate with leading European scientists of the era, as well as trips to the southern and western United States. He also...

Adiaphorism, (from Greek adiaphora, “indifferent”), in Christian theology, the opinion that certain doctrines or practices in morals or religion are matters of indifference because they are neither commanded nor forbidden in the Bible. Two adiaphorist controversies occurred in Germany after the Reformation. The first controversy arose over the religious compromise between the Lutheran theologians of Wittenberg, primarily Philipp Melanchthon, and Saxony’s civil and ecclesiastical leaders. The elector Maurice of Saxony succeeded in making the Wittenberg theologians accept, for political reasons, the Leipzig Interim (December 1548), which sanctioned the jurisdiction of Roman Catholic bishops and observance of certain rites (such as extreme unction and confirmation), while all were to accept the doctrine of justification by faith, the added word “alone” being treated as one of the adiaphora. Matthias Flacius Illyricus, a Lutheran Reformer, passionately opposed this policy on the grounds that under political pressure no adiaphora could be accepted, and, therefore, no concession could be allowed. In practice the controversy was ended in September 1555 by the Peace of Augsburg, when Lutheranism was acknowledged as a legitimate religion in the empire. The theoretical question of adiaphora, however, continued to be debated by Protestants. The Formula of Concord (1577), a Lutheran confession, attempted to settle the matter by stating that rites and ceremonies that were matters of religious indifference could not be imposed during times of controversy. Another adiaphorist controversy took place in the field of morality in 1681, when Pietists opposed the construction of a theatre in Hamburg. The Pietists denounced worldly amusements as anti-Christian, whereas Lutherans generally defended Christian freedom in such matters. Although the term “adiaphorism” was not explicitly applied in other disputes, analogous controversies occurred elsewhere. In England the Vestiarian controversy in the 1560s and ’70s dealt with the question of whether clerical vestments—declared to be “popish” by some—were theologically important.

Mars seen from Earth with the naked eye looks like a bright reddish pinpoint of light. Throw in a strong telescope and the details start to pop. Now reverse the perspective and you get NASA's Image of the Day from Friday: a view of the Earth and its moon from all the way over at Mars. NASA used two separate exposures snapped by the Mars Reconnaissance Orbiter to create the image; otherwise the moon would have been too dark to see. NASA describes the orbiter as "the most powerful telescope orbiting Mars." What's extra-cool about this far-off view is the amount of detail visible on Earth. That brownish splotch in the center is Australia. You might think the moon looks a bit cozy with our Blue Marble, but there's a reason for that: "Earth and the moon appear closer than they actually are in this image because the observation was planned for a time at which the moon was almost directly behind Earth, from Mars' point of view, to see the Earth-facing side of the moon," NASA explains. The Mars Reconnaissance Orbiter launched back in 2005, reached Mars in 2006 and has been sending back fascinating images and data from the Red Planet ever since.

INTERNAL COMBUSTION ENGINE An engine in which the combustion of fuel takes place inside the engine itself is called IC engine. The purpose of Internal Combustion (IC) engines is the conversion of mechanical energy from heat energy produced by oxidation of fuel. In 1860 JJE Lenoir developed the first internal combustion engine having an efficiency of about 5%. Otto developed another model having efficiency 11%. Then modified this engine with an engine cycle with four piston strokes, an intake, compression, expansion and an exhaust stroke. His proto type engine first ran in 1876 with better thermal efficiencies. Any machine which derives heat energy from the combustion of fuel and converts the part of this energy into mechanical work is known as heat engine. Heat engines are mainly divided as i) External combustion engine and ii) Internal combustion engine. The internal combustion engine (I.C.) engine offer some special advantages over external combustion engine (steam engine) as listed below: The thermal efficiency of IC engine(30-35%) is much higher than steam engine(15-25%). IC engine is lighter and occupies less space. It can be started quickly. It offers greater mechanical simplicity. 2. CLASSIFICATION OF I.C. ENGINES I.C. engines may be classified as follows 1) According to the type of fuel used: a) Petrol engine b) Diesel engine c) Gas engine 2) According to the number of strokes required to complete the cycle. a) 4-stroke engine b) 2-stroke engine 3) According to the cycle of operation a) Otto cycle b) Diesel cycle 4) According to the method of ignition a) Spark ignition (SI) b) Combustion ignition (CI) 5) According to method of cooling a) Air cooled b) Water cooled 6) According to the method of governing a) Quality governing b) Quantity governing 7) According to the speed of the engine a) Low speed b) Medium speed c) High speed 8) According to the arrangement of cylinder c) In line e) Radial engine

Sappho is no ordinary Ancient Greek lyric poet. Her legendary fame is disproportionate to the few fragments of poetry saved from the clutches of the early Christian church, offended by her intimate exploration of erotic passion. As a result, scattered texts believed to have been written over sketchy dates from 630-612BC onwards – mere trickles – are all that have survived. One thing we do know for certain, however, is the exact date of her “Midnight Poem”, written some time between January 15 to March 31, 570 BC, thanks to the work of astronomers of the University of Texas in Arlington. The scientists were able to calculate the date when Sappho gazed at the night sky over Lesvos based on her succinct description. The 2,500-year-old Sapphic stanza gave important clues regarding when it was written. Details from the poem, using several translations, were fed into an astronomical software program called Starry Night, taking into account the map co-ordinates for Lesvos in the northern Aegean, and other data points such as the way in which time was measured in Sappho’s time. Drawn by the reference to the Pleiades, an open star cluster that can be seen at certain times, the astronomers examined her yearning portrait of loneliness pinned to celestial bodies using a number of translations. The poem, according to a translation by J. A. Symonds in 1883 shows a meditative Sappho: “The sinking moon has left the sky, The Pleiades have also gone. Midnight comes – and goes, the hours fly And solitary still, I lie.” Astronomers describe the stanza as a “prime example of where ancient poetry and astronomy merge”. Their conclusions, published in the Journal of Astronomical History and Heritage, add another dimension to a simple poem. Astronomers describe the stanza as a “prime example of where ancient poetry and astronomy merge”.

Nursing began as a helping profession, often undertaken by nuns and military personnel during wartime. Until recent history, nursing was considered a woman’s profession. In some areas, men still receive criticism for pursuing careers in nursing. However, modern nursing is a very different field than it was before the world wars, and even before the Crimean War. Major changes began to take place in the field of nursing with the work of Florence Nightingale. The observations she made of the conditions of military hospitals led her to develop the Environment Theory, which addressed sanitation for patients, and detailed in her book Notes on Nursing. Her theory became the norm for nursing practice, and resulted in a great improvement in sanitary conditions for patients. The improvement in sanitary conditions led to a higher recovery rate in patients and decrease in complications. In 1860, Nightingale also opened the first nursing school, called the Nightingale School for Nurses, which began to regulate how nurses learned and practiced. Not only did this ensure nurses had an educational foundation of knowledge and techniques, but it helped ensure a standard of care for patients, as well. Because of the work Nightingale did for modern nursing, the oath taken by nurses when they graduate is called the “Nightingale Pledge.” Today, nursing is a much more diverse field of health care practice. Nurses are found in nearly every health care facility, and their responsibilities range from assisting patients with basic hygiene needs to giving medications and teaching them to care for themselves. In fact, some nurses become midwives and assume all the responsibilities for the care of pregnant women and delivery of their babies. The field of health care is also more diversified, so nurses can choose what area they would like to practice, and tailor their education to that field. A nurse may choose pediatrics, emergency, hospice, cardiology, or a number of other areas, and focus his or her efforts on the care of patients in that area. Each area requires a different skill set, and nurses may take continuing education courses to strengthen that skill set.

Normally the color blindness is a genetic condition. The green, blue and red color blindness is usually passed down from the parents. The gene which is in charge for the state is carried on the X chromosome and this is the grounds why many more men are affected from this problem as compare to women. There are many reasons of this problem. There are some interesting facts from which the people are not completely familiar, these are as follows: Normally the effects of color vision deficiency can be soft, moderate or ruthless depending upon the deficiency. If someone is suffering from inherited color blindness then their condition will stay the same all through their life, it won’t get any healthier or worse. Generally, there are three types of cone cells and each kind has a different sensitivity and compassion to beam wavelengths. One kind of cone perceives blue light, while another perceives green and the third one perceives red shade. When someone looks at an object, the light enters into their eye and arouses the cone cells. The brain in this state interprets the signals from the cones cells so that one can easily see the color of the item. The green, blue and red cones all work together allowing people to see the whole variety of shades. For example, in a case when the blue and red cones are simulated in a certain manner then one will see the purple color. We can understand that you are tired being a colorblind and you want to see the colors just like the normal individuals. That is why we have for you the Vision. Use the software to see colors just like any normal individual. The accurate physical causes of color blindness are still being investigated but it is assumed that color blindness is by and large caused by flawed cones or sometimes by a mistake in the pathway from the cone to the brain. The people with usual color vision have all the three types of cone or pathways working properly but color blindness takes place when one or more than one cone types are out of order. For example, in case if the red cone is damaged then you won’t be able to see the colors containing red shades noticeably. Most of the people with color blindness can’t differentiate the definite shades of green and red color. Try Vision colorblind test. You can find out whether you are colorblind or not.

What is Cognitive Behavioural Therapy (CBT)? When we think about cognitive behavioural therapy we think about those with behavioural problems. Cognitive behavioural therapy, also known as CBT is reviewing an individual’s mood, emotions, behaviour and reactions. This is analysed in line with how an individual reacts around other people, environments and objects. With all types of therapy you will find pros and cons, however cognitive behavioural therapy has proven to be a great asset for children and young people, as it allows more opportunity to explore their emotions and discuss reasoning behind behaviour changes. Through CBT, we can identify other avenues leading to behavioural problems such as stress and anxiety. Cognitive behavioural therapy was by Albert Ellis relating to his work of Rational Emotive Behavioural Therapy. From this, he broke down his techniques and processes and created CBT. Through his study, it was proved that emotions had a huge impact on how a person perceives themself. The studies were very intense and have shown how irrationality, negativity, positivism and goal setting all link with cognitive approaches. Usually, the use of CBT is more effective when there is a group, this will give more benefits to the individuals who can share feelings and emotions as well as experiences which support others. While in therapy groups, direct observations are carried out looking at elements of behaviour and possible links to psychological disorders. Like to learn more about Cognitive Behavioural Therapy?

About this lecture The mosaic of the Transfiguration covers a surface of 46 square meters in the basilica of the Monastery of St. Catherine, in Sinai. Made in the 6th century at the behest of Emperor Justinian, it has a rich chromatic range of glass paste, gold and silver tesserae and stone tesserae. The mosaic is a jewel of early Byzantine art. Over the centuries, it has suffered extensive damage due to earthquakes and water infiltrations. Some of the signs of deterioration were the detachment of the preparatory layers from the wall, bulges in the mosaic surface, and lacunae (gaps) in the tesselatum. The area of the large figure of Christ was so badly decayed that the mosaic was close to collapse, as repoted by Kurt Weitzman on the National Geographic in an article published in 1964. These problems led the monastic community to undertake a delicate program of consolidation and conservation of the mosaic. The CCA, Centro di Conservazione Archeologica, was asked to carry out the restoration work. Works began in 2005, thanks to funding made available by the Emir of Qatar, Sheik Hamad bin Khalifa al Thani, following a conservation project developed by the CCA in 2001 for the Getty Conservation Institute (GCI).

Although a stroke is the fifth leading cause of death in the US, very few people understand how to recognize the signs and symptoms. Some risk factors such as such as age, race, and heredity can’t be changed. However, with the right knowledge, risk factors can be addressed and 80% of strokes can be prevented. Types of stroke A stroke occurs when the brain’s blood supply is severely reduced or completely stopped. This causes brain cells to become damaged or die due to lack of oxygen. Because the brain becomes severely damaged without oxygen, it is important to act quickly. A stroke can cause long-term damage, disability, and even death. Here are the different types of strokes: Ischemic Stroke – This type of stroke occurs when a fatty plaque clot or mass clogs a blood vessel and stops blood flow to brain cells. Hemorrhagic Stroke – This type of stroke occurs when a damaged or weakened vessel ruptures and bleeds out into the surrounding brain tissue. The blood gathers and forms a bruise which compresses the brain cells and causes them to die. TIA (Transient Ischemic Attack) – A TIA is a medical emergency. It is referred to as a “mini stroke” and mimics the symptoms of a stroke. It is caused by a temporary clot and does not cause permanent damage to the brain. However, about 15% of all strokes happen after a TIA occurs. How to spot a stroke Symptoms of a stroke are reflected in the areas of the body controlled by the damaged brain cells. Remember to act F.A.S.T to reduce the damage caused by a stroke. Learn to manage the risk factors Although not all risk factors are preventable, there are many that can be addressed to minimize the possibility of experiencing a stroke. Along with monitoring your overall health, visit a physician to do a yearly health exam. - Manage high blood pressure – HBP is the leading cause of strokes and is highly controllable. - Control cholesterol - Eat a healthy diet - Be active and maintain a healthy weight - Manage diabetes and control blood sugar - Do not smoke

Angola Table of Contents Displaced persons walk to a camp in Cuanza Sul Province. Courtesy Richard J. Hough Although Portuguese was Angola's official language, the great majority of Angolans (more than 95 percent of the total population) used languages of the Bantu family--some closely related, others remotely so--that were spoken by most Africans living south of the equator and by substantial numbers north of it. Angola's remaining indigenous peoples fell into two disparate categories. A small number, all in southern Angola, spoke so-called Click languages (after a variety of sounds characteristic of them) and differed physically from local African populations. These Click speakers shared characteristics, such as small stature and lighter skin color, linking them to the hunting and gathering bands of southern Africa sometimes referred to by Europeans as Bushmen. The second category consisted of mestišos, largely urban and living in western Angola. Most spoke Portuguese, although some were also acquainted with African languages, and a few may have used such a language exclusively. Data as of February 1989

The dental arch is the length and width of the line in which a person's teeth are set into their upper and lower jaws. The depth and diameter of this arch are vital to the long-term health of the teeth in particular and the mouth in general. If the arch does not conform to satisfactory standards, it may result in dental and health problems. Since there are a standard number of teeth in humans, the size of the dental arch is of vital importance in determining how the teeth are positioned when they appear. While the arch can expand as a child grows, a small arch will force the teeth to grow close together. This can result in overlapping and improperly positioned teeth. Teeth may tilt at an awkward angle, putting pressure on gums when food is being chewed. This can ultimately lead to compromised gums or infections. If the dental arch is too narrow, some teeth may be selected for extraction. This will allow more room for the other teeth; in young patients with teeth that are still in the process of growing, teeth may to some degree correct themselves with the new space. At other times, braces or other corrective measures, such as the insertion of spacers, can be taken. Many individuals have their wisdom teeth removed to prevent crowding in the back of the mouth, at the very ends of the dental arch. Failure to remove them can result in impaction and considerable pain for many. Alternately, if the dental arch is too long or too wide, teeth may come in with large spaces between them. This is fairly common, and can easily be seen in individuals with gaps between their front teeth; in these cases, the front portion of the dental arch may be too wide. Braces can often be applied in order to shift the teeth forward into the proper position. The dental arch also determines the proper placement of the teeth around the tongue; improperly formed arches can force teeth to interfere with speech. Consequently, some speech problems can be solved by adapting teeth to better fit the space available in the individual's mouth. A narrow arch can also present an individual with difficulties chewing and make thorough brushing difficult. Problems with the arch are most common in very young or older individuals. The proper fitting of dentures requires that plates be molded to the exact specifications of an individual's mouth. A shortened arch may result in difficulties fitting dentures, and can cause abnormal pain in the face, jaw, or gums.

What a shock! You get up in the morning to tour your vegetable garden, in perfect condition the day before, only to find some of the young plants mowed down, cut off at the base. What could have done it? The answer is “a cutworm”, the larva of a moth (one of many species of Euxoa). The moth lays its eggs in the soil in the fall or early spring, often in weeds or grasses near the garden. The worm itself (actually a caterpillar) is often greyish and rolls up into a C when it is disturbed. Cutworms can cause considerable damage to young plants, especially vegetables, but also seedlings of annuals, perennials and others. After it hatches in late spring, the cutworm crawls out of the soil at night and chomps away the base of the plant until it crashes to the ground. To stop the disaster, you’ll have to do a bit of prospecting. With a flashlight, go out into the garden the next night and look for the culprit (it starts to move to the surface of the soil at dusk): cutworms never go very far and should be in the same area where the plants were cut down the day before. Or, if you prefer working in daylight, dig around in the soil near the fallen plant with a trowel, about 2 inches (5 cm) deep: a cutworm is not hard to find. Or be proactive and protect the base of your plants and your transplanted seedlings before cutworms attack. Cut the bottom off a few cans, plastic pots or plastic, styrofoam or cardboard cups, thus forming a tube. You can even use the tube from a roll of toilet paper! Place a tube barrier around each seedling, pressing the lower part of the barrier into the soil to a depth of 1 inch (2 cm). With a barrier around the base of the plants’ stem, cutworms, which always act right at soil level, will find nothing to eat and will either die or move elsewhere.

Corals have long been popular as souvenirs, for home decor, and in jewelry, but many consumers are unaware that these beautiful structures are made by living creatures. Fewer still realize that corals are dying off at alarming rates around the world. Coral reefs are some of the most biologically rich and economically valuable ecosystems on Earth, but they are threatened by an increasing array of impacts—primarily from global climate change, unsustainable fishing, and pollution. Strong consumer demand for coral, heightened over the holiday season, is another factor that is contributing to the decline of coral reefs. Each year, the U.S. imports tons of dead coral for home decorations and curios. Most of these corals are shallow-water species. The U.S. is also the world's largest documented consumer of Corallium, red and pink corals often used to create jewelry. Finished pieces of jewelry and art crafted from this type of coral can fetch anywhere between $20 and $20,000 in the marketplace. Continued consumer demand is contributing to the decline of these delicate corals around the world. Commercial harvesting to satisfy the demand for coral jewelry has reduced colony size, density, and age structure of Corallium over time. Harvesting is also lowering the reproduction capability of this species and is decreasing its genetic diversity. Research indicates that removal of red and pink corals for the global jewelry and art trade is also leading to smaller and smaller Corallium in the wild. Corals grow very slowly, are extremely long-lived, and take years to reach maturity. It takes corals decades or longer to create reef structures. Once coral is harvested—especially when it's extracted at a young age—surrounding coral beds often do not recover. That's why it's best to leave corals and other marine life on the reef. Remember: corals are already a gift. Don't give them as presents. Did you know? When it comes to coral jewelry, there is one exception to the rule. Black coral from Hawaii is the only coral that is legally harvested in the U.S. This fishery is carefully managed by the state of Hawaii and the federal government to ensure that this species of coral is not overexploited. State certified divers use sustainable harvest techniques to harvest black corals—the official gemstone of Hawaii—to produce precious coral jewelry. Last updated: 01/20/23 How to cite this article

Croatian Translation Services Croatian belongs to the South Slavic group of the Slavic branch of the Indo-European language family. Its history roots back to the breakup of Yugoslavia when the language, Serbo-Croatian (spoken among Serbs, Croats, Bosniaks, and Montenegrins) split into three mutually intelligible languages — Serbian, Croatian and Bosnian. These languages were formed on the basis of political reasons, rather than linguistic reasons. Serbia became part of the Ottoman empire, while Croatia was under Austro-Hungarian rule, and eventually their languages evolved into different dialects and alphabets. In the 19th century, however, Serbian and Croatian became one language when there were efforts to create an independent South Slavic state. After gaining independence in 1991, Croatia reformed Croatian to separate it from Serbian. According to Ethnologue, Croatian is spoken by around 5.5 million people worldwide. Where is Croatian Spoken? Did you Know? “Croatian is a phonetic language. If you learn to pronounce the letters, you can sound out any word.” (adventuresinfluency.com) 4 Easy Phrases in Croatian! Population vs. Internet Penetration As of 2020. Source: Croatian Translation Tips • There are three genders in the Croatian language – masculine, feminine and neuter. • The number forms include singular, plural, with some vestiges of dual. • Verbs in Croatian have three persons – first, second, third. • Croatian is a pro-drop language – personal pronouns can be dropped as the verb ending makes the person clear. • The neutral word order in Croatian is Subject-Verb-Object but other orders are possible.

Some common and dangerous air pollutants found in cities can be absorbed by plants at far greater rates than ever suspected. The discovery has big implications for modeling how vegetation affects pollutants, as well as how particles in the atmosphere affect human health and global warming. The finding comes from a fruitful and unusual collaboration of plant geneticists and atmospheric scientists. The plant scientists found the genes used by plants and the conditions under which they are activated to allow more volatile organic compounds (VOCs) to be absorbed, while the atmospheric scientists lugged equipment around the globe to verify that the plants were indeed sucking up pollutants in the real world. “It’s been hard to measure this in the real world,” said Thomas Karl of the National Center for Atmospheric Research. “That’s why we hauled this instrument all around the world.” Karl led the field work which involved gathering and immediately analyzing air samples in remote forests using a 200-pound, washing machine-sized mass spectrometer. He is also the lead author on a paper reporting the discovery in the Oct. 21 issue of Science Express. Read the entire article in Discovery News by clicking here.

It can also refer to the chart or map made by analysing a region from the air. This is typically done using aeroplanes , and in history with balloons . Aerial survey should be distinguished by satellite imagery technologies because of its better resolution, quality and atmospheric conditions. Today, aerial survey is often recognized as a synonym for aerophotogrammetry, part of photogrammetry where the camera is placed in the air. Measurements on aerial images are provided by photogrammetric technologies and methods. Aerial surveys can provide information on many things not visible from the ground.

NASA Research to Help Aircraft Avoid Ocean Storms, Turbulence A prototype system could provide commercial airline pilots with key weather and turbulence forecasts when flying over remote regions of the ocean where little real- or near-real-time data is available now. The NASA-funded system, being developed by the National Center for Atmospheric Research (NCAR), combines computer models and data from five operating NASA satellites with an artificial intelligence system to predict turbulence. The system is on track for testing next year, with the goal of ultimately giving pilots a regularly updated picture of potential storms over the ocean so that they can fly away from or around danger. This photograph, acquired in February 1984 by an astronaut aboard the space shuttle, shows a series of mature thunderstorms in southern Brazil. Deep Convective Clouds A 2009 astronaut photo from the International Space Station (ISS) of deep convective clouds, seen from above, over the Atlantic Ocean. Free standing and embedded towering convective clouds are particularly dangerous to aircraft flying over the open ocean. Turbulence Waves and Deep Convection NASA and NCAR are working to develop a near-real-time forecast that identifies turbulence from breaking gravity waves that are generated by rapidly rising deep convection. This image from NASA's MODIS instrument (Moderate Resolution Imaging Spectroradiometer) shows gravity waves over the ocean. Atmospheric gravity waves (also called atmospheric internal waves) occur either when a uniform layer of air blows over a large obstacle, like a mountain or island or when rapidly rising, deep convection perturbs a stable layer from below, as in the oceanic case we have illustrated. When the air hits the obstacle or is disturbed by rising convection from below, the horizontal ribbons of uniform air are disturbed, which forms a wave pattern. This wave pattern in the air impresses itself onto sea waves when it touches the surface of the ocean. In addition to the surface mimicking the wave pattern, wave clouds can form as well, creating potential turbulence for aircraft. Slicing through the Atmosphere NASA uses advanced satellite instruments to study the atmosphere. One instrument, CALIPSO, uses a lidar system to make a 3-D view of clouds. CALIPSO data will be used as a source of precise validation and tuning for these NASA/NCAR applications under development.

Photo with 87 notes More than 3,200 years ago, life was abuzz in and around what is now this modern-day Israeli metropolis on the shimmering Mediterranean shore. Yet within 150 years, according to experts, the old world lay in ruins. Experts have long pondered the cause of the crisis that led to the collapse of civilization in the Late Bronze Age, and now believe that by studying grains of fossilized pollen they have uncovered the cause. In a study published Monday in Tel Aviv: Journal of the Institute of Archaeology of Tel Aviv University, researchers say it was drought that led to the collapse in the ancient southern Levant.

Slovak preserves the Common Slavic contrast between short and long vowels (referring to the length of the vowel's sound), with the long vowels represented in writing by an acute accent mark. Slovak also has developed a set of diphthongs (ia, ie, iu, ou, and uo�"the latter written as ) that function as long vowels. The sounds r and l function as either consonants or vowels; as vowels, they can be either long or short. Slovak shares with the Czech language the spelling of the consonants c, š, and ", pronounced ch, sh, and zh, respectively. The Slovak language has gained the soft dental consonants t', d', l', and , but it lacks a soft r. Compared with Czech, Slovak word structure has been simplified. Stress falls on the first syllable of a word. Slovak nouns have one of three genders (masculine, feminine, neuter) and six cases (nominative, genitive, dative, accusative, instrumental, locative). The vocative case has been virtually lost. Adjectives agree with nouns in gender, number (singular and plural), and case. Verbs have two tenses (past and present) and two aspects (perfective and imperfective), the latter indicating the duration of the verb's activity. Many verbs have an iterative form, which expresses repeated action. Slovak has a complex numeral system and a well-developed system of indefinite pronouns and adverbs. Slovak word order generally places the most informative elements at the end of a sentence, often violating the language's basic subject-verb-object sentence structure. Food and Drink Popular drinks include Slovak beer, wine and mineral waters. Borovicka (strong gin) and slivovica (plum brandy) are particular specialties with wine from the Tokaj region and sparkling wine from the Bratislava region.

- Galactic Star Formation and the ISM - Astrochemistry and the Birth of Massive Stars - The Dust Grain Ice Formation Inverse Problem Extragalactic Star Formation The study of how stars form under various chemical and physical conditions in the Universe is crucial in order to get better insights on how larger structures such as galaxies form and evolve in time. Stars form in dense condensations of gas. It is thus important to determine as precisely as possible the properties of this gas (e.g. gas temperatures and pressures), and especially how they vary from one galaxy to another. Galaxies vary in type and characteristics: some experience a burst of star formation activity in their nucleus, some are are quiescent, some are merging (see Figure 1), some host black holes in their central region. All these different environments directly influence the properties of the gas and thus the way stars are forming within it.

Researchers at Aalto University in Finland have developed a new and significantly cheaper method of manufacturing fuel cells. A noble metal nanoparticle catalyst for fuel cells is prepared using atomic layer deposition (ALD). This ALD method for manufacturing fuel cells requires 60 per cent less of the costly catalyst than current methods. Fuel cells could replace polluting combustion engines that are presently in use. However, in a fuel cell, chemical processes must be sped up by using a catalyst. The high price of catalysts is one of the biggest hurdles to the wide adoption of fuel cells at the moment. The most commonly used fuel cells cover anode with expensive noble metal powder which reacts well with the fuel. By using the Aalto University researchers’ ALD method, this cover can be much thinner and more even than before which lowers costs and increases quality.

The actual James Webb Space Telescope, now being built, is to be launched in 2013. The life-sized model was built by the Northrop Grumman Corp. to give people a better understanding of its size, scale and complexity. NASA said the German museum has an extensive telescope collection, including the Fraunhofer Refractor, which was used to discover Neptune. The model is to be displayed at the museum Oct. 13-28, in conjunction with a nearby meeting of Webb telescope scientists and engineers. NASA said the display will allow people working on the project to see the life-sized model. The space agency said the model was designed for an environment subject to gravity and weather. It weighs 12,000 lbs. and is approximately 80 feet long, 40 feet wide and 40 feet tall. It requires 2 trucks to ship it and assembly takes a crew of 12 approximately four days. The James Webb Space Telescope is a joint project of NASA and the European and Canadian space agencies.

“Since the start of the industrial revolution, mankind has been burning fossil fuel (coal, oil, etc.) and adding its carbon to the atmosphere as carbon dioxide. In 50 years or so this process, says Director Roger Revelle of the Scripps Institution of Oceanography, may have a violent effect on the earth’s climate… Dr. Revelle has not reached the stage of warning against this catastrophe, but he and other geophysicists intend to keep watching and recording. During the International Geophysical Year (1957-58), teams of scientists will take inventory of the earth’s CO2 and observe how it shifts between air and sea. They will try to find out whether the CO2 blanket has been growing thicker, and what the effect has been. When all their data have been studied, they may be able to predict whether man’s factory chimneys and auto exhausts will eventually cause salt water to flow in the streets of New York and London.” - “One Big Greenhouse“, Time Magazine, May 28, 1956 As part of the International Geophysical year, Revelle’s post-doctoral associate David Keeling established the CO2 monitoring station atop Mauna Loa in Hawaii (photos taken by an embarrassingly excited S. Donner). The now famous Keeling Curve is the longest continuous record of atmospheric CO2 measurements.

6 Practical Cooperative Learning Strategies for Organizing Student Inquiry Cooperative learning is an integral part of a teacher’s tool kit, and it is the central pedagogical tool of Science As Inquiry. Every activity in Science as Inquiry shows how cooperative learning can be used as a way to organize students to do inquiry. In Chapter 1 of Science as Inquiry, six cooperative learning structures or strategies are presented in detail. Each cooperative learning strategy is illustrated by a science activity, which you can use to help your students learn how to learn in teams, and for you to become familiar with the diversity of cooperative learning approaches. The chart below outlines the cooperative learning structures. Collaborative inquiry, one of the cooperative learning strategies in which the distribution of roles leads to interdependent as well as individual responsibility with a team. Students work in teams of four with each student taking on one of four roles: communicator, materials manager, tracker or checker. With teams of five, one student takes on the role of coach. Each of the cooperative learning structures developed in the text is illustrated with a science activity. In the case of collaborative inquiry, the example science activity is The Footprint Puzzle. In this cooperative learning activity, teams are asked to investigate the footprints of dinosaurs that are based on prints found in rocks during the Cretaceous Period of geological time. In the context of geological science, students are asked to collaborate on what they observe in the tracks before them, and what interpretations they can make about the dinosaurs based on the tracks. Students use the Data Recording sheet shown below. Each student takes on a different inquiry role, as identified here, and work together as a team to investigate the puzzles. Note that there are two sets of tracks. Students should work on the first set for a few minutes. Then you can inform the students that additional tracks have been located, and the second set of tracks shows how the new tracks are related to the first set that the students observed. How does the second set of tracks affect the students' hypotheses and interpretations?

Does children's literature portray the authentic perspectives of children, or does it present the views of the adults who write, sell, and review the books? How does it demonstrate the ways in which perceptions of childhood have developed over the centuries? How are issues of censorship and freedom of speech brought to light in children's books? Addressing these and many other issues, Crosscurrents of Children's Literature: An Anthology of Texts and Criticism is the only anthology of classic and contemporary readings in children's literature to combine primary works with related critical essays. Organized thematically around modern critical debates, the selections explore how children's literature integrates instruction and entertainment, oral and written traditions, realism and fantasy, words and pictures, classics and adaptations, and perspectives on childhood and adult life. Illuminating the rich diversity of children's literature studies, the book incorporates approaches from several different fields including psychology, education, history, cultural studies, and literary criticism. It spans a wide range of literary periods and genres, balancing contemporary and historical texts, excerpts and longer selections, traditional and nontraditional materials, and English and translated works. The volume includes Native American and African American writings and offers insights into a variety of cultural and ethnic traditions. It is enhanced by introductory essays, illustrations, an alternate table of contents organized by genre, a timeline, and a bibliography of critical works. An Instructor's Manual and a Website (http://crosscurrentsoup.org) provide additional helpful resources. Examining how literary forms and genres, diverse influences, and evolving attitudes toward childhood have shaped the field of children's literature, Crosscurrents of Children's Literature: An Anthology of Texts and Criticism encourages students and other readers to challenge common assumptions about children, childhood, and children's books.

Wales has become the first country in the world to formally monitor and report on changes to its Ecological Footprint. In May it “weighed in” with a report, Wales’ Ecological Footprint – Scenarios to 2020, which shows how the country’s Footprint has grown in recent years, and identifies policies that could halt and even reverse the trend. Wales’ Ecological Footprint grew at a rate of about 1.5 percent a year between 1990 and 2003, according to the report, produced by Stockholm Environmental Institute – York and published by Wales’ Environment Minister Jane Davidson. If everyone on Earth used as much material resources and generated as much carbon emissions as the average person in Wales, it states, humanity would need another two planets. Policies to encourage efficiency in areas of housing and use of energy; personal travel; and food consumption could enable Wales to curb its growing appetite for resources, reducing its Ecological Footprint by as much as 10 percent in the next 12 years. The report calls upon the government to work toward goals established in the ambitious One Planet Wales Campaign, by Global Footprint Network partner WWF Cymru, which sets a target of achieving a one-planet Footprint by 2050. Wales has chosen the Ecological Footprint as one of five headline measures of progress towards sustainable development. It is currently engaged in a number of plans to limit its environmental impact, such as working to have all new buildings be carbon neutral by 2011 and striving to get all its energy from renewables from 2020. It has also set a recycling target of 70 percent of municipal waste by 2025. Read the report (3,982 KB) Learn more about how Wales is using the Footprint Post Comments • Read Comments (0)

Roadway panels from Solar Roadways consist of a high-strength surface layer with embedded solar cells, a middle layer containing a microprocessor board and related circuitry, and a base plate that distributes power. Shown above is what an actual roadway created with this technology could look like. “There’s 25,000 square miles of road surfaces, parking lots and driveways in the lower 48 states. If we covered that with solar panels with just 15 percent efficiency, we’d produce three times more electricity than this country uses on an annual basis, and it’s almost enough to power the entire world,” said Scott Brusaw, co-founder of Solar Roadways, in a segment of Your Environmental Road Trip, a new film that explores cutting-edge energy solutions.

Classes are shown with their simple attributes and methods listed. Some attributes are depicted using associations (relationships) rather than actually being listed in the class block. These associated attributes refer to complex objects which should also be shown in the diagram. The collaboration diagram indicates methods to be contained in a class with methods posted as relationships. For instance the Schedule class has a findSeat(route, preference) method. Temporary visibility between classes is depicted using dashed lines. Methods to be included in the class will include: The following optional characters in front of class attributes or methods depict meaning as shown below: If the method or attribute is listed in italics text, it is abstract. If text is underlined, the method or attribute is static. Multiplicity is shown the same as in the Domain Model. The diagram below illustrates that the * next to the menuItem indicates multiplicity of the menuItem object.

In regard to free blacks during that period, Berlin writes: "A considerable portion of these new arrivals — fully one-fifth in New Amsterdam, St. Augustine, and Virginia's eastern shore — eventually gained their freedom. Some attained modest privilege and authority in mainland society." Of free blacks in the 17th-century Chesapeake region, he explains: "When they found the weak points, they burst the constraints of servitude, race, and impoverishment. The fluidity of colonial society, the ill-defined meaning of slavery, and the ambiguous notions of race allowed Atlantic creoles to carve a place for themselves in the Chesapeake and occasionally achieve a modest prosperity, despite the growing weight of discriminatory legislation." A fascinating aspect of this history involves the legal circumstances in the Chesapeake:Like their white neighbors, free people of color were a litigious people. Throughout the 17th century, they sued and were sued with great frequency, testifying and petitioning as to their rights. Though many black men and women fell prey to the snares of Anglo-American jurisprudence — bastardy acts, tax forfeitures, and debt penalties — their failure was rarely one of ignorance, as members of the charter generation proved adept at challenging the law on its own terms and rarely abandoned a losing cause without appeal.The rise of plantation slavery brought wide-ranging change. Berlin writes: "The touchstones of the charter generations — linguistic fluency, familiarity with the commercial practices of the Atlantic, knowledge of European conventions and institutions, and (occasionally) their partial European ancestry — vanished in the age of the plantation." 15 February 2005 The "Charter Generation" of American Slavery Geitner Simmons of Regions of Mind has a fascinating post in response to the new PBS series on Slavery and the Making of America. He quotes from Ira Berlin's Many Thousands Gone: The First Two Centuries of Slavery in North America (Harvard Belknap, 1998): Posted by Joel at 2/15/2005 08:11:00 PM

“Miriam died... and was buried. And the community was without water to drink” Numbers 20:1-2 Follow The JC on Twitter This odd juxtaposition of these verses suggests a connection between Miriam’s death and the people’s thirst for water. The Midrash explains that as long as Miriam was alive, a well accompanied her, bringing water to the people in the desert. When Miriam died, the well dried up and disappeared. Like many things in life, as long as the well was there, no one paid attention to it. Only after it dried up did they realise how dependent they were on it. Until then, no one realised that it was Miriam who sustained the people during their long journey. Miriam’s well, as a source of nourishment and healing, remained a powerful image throughout Jewish history. It was part of Jewish life in the 11th–12th centuries in France. At that time, the custom among French Jews was to refrain from eating or drinking between the afternoon meal and nightfall. This was a particularly hard burden on long Shabbat afternoons in the summer. Some communities believed that on Shabbat the water of Miriam’s well miraculously mingled in the water of their wells, and anyone who drank of these waters would be cured of any disease or ailment. At the end of Shabbat, the Jews would run out to their wells to draw water, while the healing waters of Miriam’s well were still available. Thus, the long “fast” on Shabbat afternoon finished with the cool waters of Miriam’s well.This custom continued until the advent of the Black Death in Europe. With Jews being blamed for poisoning the wells, it became too dangerous to gather around the wells at the end of Shabbat — and so the custom disappeared.

“Joe” was a Parasaurolophus, a duck-billed (hadrosaurid) dinosaur that lived throughout western North America around 75 million years ago. A fully adult Parasaurolophus is notable for having a long and hollow bony tube on the top of its skull, which scientists speculate was used like a trumpet to blast sound for communication, as well as a billboard for visual display. Although partial skulls and skeletons of full-grown Parasaurolophus have been known for over 90 years, scientists previously knew little about how Parasaurolophus grew up. Adult Parasaurolophus measured about 25 feet in total body length and weighed an estimated 2.5 tons. They were primarily quadrupeds, but may have walked on just their hind legs at times. Parasaurolophus were herbivores, using their sharp beaks to chop off plants, which were then ground up on their tightly packed teeth. How do we know that “Joe” is a Parasaurolophus? “Joe” looks very different from adult Parasaurolophus, especially because it lacks the prominent crest that adults have. However, many other features in the skull of “Joe” match up with adults, such as the shape of certain openings in the bone and the shape of the bony beak margin. As an additional, circumstantial, piece of evidence, Parasaurolophus is the only type of crested dinosaur known from the 75 million year old rocks in Utah where “Joe” was found. Thus, it is simplest to assume that “Joe” is a Parasaurolophus. How do you say the name? The name “Parasaurolophus” is quite a mouthful! It is pronounced “PAIR-uh-SORE-AH-luf-us”.

Sherman's March to the Sea 1864:The March to the Sea was the culmination of Union General William T. Sherman's 1864 campaign during the American Civil War (1861-1865) and was a devastating example of "total war." Confederate hopes in 1864 hinged on frustrating Union forces in the field and forcing Abraham Lincoln out of office in the November elections. However, this optimism was dampened by Sherman's success in the battle of Atlanta that same year. Riding on the wave of this victory, Sherman hoped to push his forces into Confederate territory, but his plan was hindered by a Confederate threat to the army's supply lines. After much delay, he boldly chose to abandon these, forcing the army to live off the land for the entirety of the 285-mile march to Savannah, destroying all war-making capabilities of the enemy en route, and inflicting suffering not only on Confederate troops, but also on the civilian population. Despite the vilification that this brutal tactic earned him, the march was a success. Supported by contemporary photographs, detailed maps, bird's eye views, and battlescene artwork, this title explores the key personalities, strategies, and significant engagements of the march, including the battles of Franklin and Nashville, and the ultimate fall of Savannah to the Union, to provide a detailed analysis of the campaign that marked the "beginning of the end" of the American Civil War.

Introduction to Plate Tectonics : The Earth's upper, rigid layer is broken into several plates which are in constant motion to one another. Most earthquakes and volcanoes occur as result of these plate boundaries. Volcanoes of the WorldEvery volcano in the world that has erupted within the past 10,000 years or is considered potentially active and many extinct volcanoes are listed. If you have interesting material about a volcano (or a region), in particular images, news, eye-witness accounts, etc. you like to share, please get in touch with us or send us the material for review. Quick links: Volcano News | Volcanoes Today | Active Volcano Map | Volcanic glossary | Volcano Photos Tuesday, Sep 30, 2014 Following several days of increased pressure at Kilauea's summit, lava activity is picking up on the June 27th flow with new flows continuing to move to the north, on a pathway leading slightly away from the town of Pāhoa for now. ... Sunday, Sep 28, 2014 Eruptive activity at the Holuhraun fissure remains stable. The lava flows continue to expand towards the north and particularly to the east, now over a snow-covered landscape as winter conditions set in. ... Yesterday's eruption might have caused more than 30 fatalities, Japanese press reports. Most of them were apparently killed by heart and respiratory failure after inhaling ash when caught in the outer areas of a pyroclastic flow or ash cloud descending the mountain. ... Saturday, Sep 27, 2014 A large explosive eruption occurred at Japan's second highest volcano today at 11:56 local time. An explosion produced an ash plume that rose approx. 4 km and a large pyroclastic flow that swept down the southwestern flank. ... Thursday, Sep 25, 2014 Strombolian explosions have returned to the summit vents, although so far, these have been rare and small. At the same time, the effusive eruption with lava flow emission from the vent at 650 m a.s.l. at the northern base of the crater terrace complex continues with little changes. ... More on VolcanoDiscovery: World-wide volcanic activity reports, updated almost daily. The term for all fine-grained volcanic products fragmented during explosive eruptions.

From the New Latin Prussia, a Latinization used by Peter of Dusburg of a Baltic (Old Prussian, or perhaps Lithuanian or Latvian) autonym. The Middle English designation for the region, Pruce, derives from the same Latinization and is the source of the terms pruce and spruce. - (chiefly historical) A geographical area on the Baltic coast of northeastern Europe. - (historical) A Baltic country located in this area, conquered by the Teutonic Order and ultimately absorbed into Germany. - (historical) A German province which was originally located in this area but later greatly expanded, and which was the predecessor to and a member of the German Empire; abolished as an administrative unit at the end of the Second World War. In the Baltic languages the 'u' is long; it was also long in Middle English, but it has become short in modern English.
