BACKGROUND: Uveitis is a condition characterized by inflammation in the eye. Specifically, the part of the eye known as the uveal tract. The uveal tract is the middle layer of the eye that is considered the nutritional layer because it is rich in blood vessels. Uveitis has a number of subcategories depending on which part of the uveal tract is inflamed. Because of its rich blood supply, the uveal tract is a natural target for diseases that start in other parts of the body. It can also be caused by other problems within the eye, such as cataract or other changes in the lens or ulcer. Symptoms of uveitis can be as simple and vague as blinking, squinting or watery discharge from the eye, or it can be as severe as total vision loss in that eye. In uveitis, the cornea, which is normally clear, becomes blue and hazy or dull. The cornea can also become cloudy and the white of the eye can become red and swollen. The colored part of the eye can even become red in some cases. In up to 75 percent of uveitis cases, the c

The pulmonary valve is too tight so that the flow of blood from the right ventricle of the heart into the pulmonary artery is impeded. This means the right ventricle must pump harder than normal to overcome the obstruction. If the stenosis is severe, babies may become blue (cyanotic). Older children often have no symptoms. Treatment is needed if the pressure in the right ventricle is higher than normal. The obstruction can usually be relieved by a procedure called balloon valvuloplasty or by open heart surgery during which the stenotic valve is opened. The outlook after either procedure is favorable. Common Misspellings: pulmanary stenosis, pulmenary stenosis

Social Sciences and History The following sample questions do not appear on an actual CLEP examination. They are intended to give potential test-takers an indication of the format and difficulty level of the examination and provide content for practice and review. For more sample questions and information about the test, see the CLEP Official Study Guide. Question 2 of 9 Anti-Jewish pogroms in Russia in the late 19th century had which of the following effects? They accelerated intermarriage between Jews and non-Jews in Russian cities. Jewish emigration to Britain and the United States increased dramatically. The League of Nations issued an official condemnation of anti-Jewish policies. The Russian army rose up against the Tsar and attempted a coup in protest. They led Poland and Germany to resettle large numbers of refugees from Russia. Want to get a feel for the tests? Try out sample questions from actual CLEP exams in the subject of your choice.

What’s this thing called the glycemic index? Is it a meal- planning method? Does it work? The glycemic index is a hot topic these days, it seems. But it’s a controversial topic, too. This week, I thought I’d try and shed some light on the glycemic index and hopefully clear up any misconceptions you may have. The glycemic index (GI) has actually been around for about 20 years. Researchers at the University of Toronto came up with this tool back in the 1980’s. GI is really a ranking system of carbohydrate foods based on how they affect blood glucose levels. Carbohydrate foods are assigned a number between 0 and 100 based on that effect. Foods that have a GI of more than 70 are considered to be “high,” foods with a GI between 55 and 70 are “moderate,” and foods with a GI below 55 are “low.” Why do foods have different GIs? Much of the reason has to do with how quickly the food breaks down during digestion, and therefore, how quickly blood glucose levels go up after eating. Let’s take a look at some foods and see

Education for Sustainable Diversity (ESD), as defined by the Office for Inclusion, is the practice of acquiring knowledge about and becoming aware of ways in which our beliefs and biases impact the quality of relationships among people from different cultural groups around the world. The goal of the Office for Inclusion is to support a campus community that understands how to fully integrate the University’s core values of diversity and inclusion into campus work and learning environments. ESD serves to provide opportunities for people to better understand the complexities of and synergies between, the issues threatening our intercultural sustainability and assess their own values and those of the society in which they live in. ESD seeks to engage people in negotiating a sustainable future, making decisions and acting on them. To do this effectively, the following skills are essential to ESD: - Envisioning -- being able to imagine a better future. The premise is if we recognize and begin to understand the iss

Discrimination by Race and Color The Missouri Human Rights Act (the Act) protects individuals against discrimination on the bases of race and color. The Act applies to employers with six or more employees, including state and local governments. It also applies to employment agencies, “temp services,” labor organizations, landlords, housing providers, property managers, those selling houses, realtors and those providing loans for dwellings. The Act also covers all businesses that offer their goods and services to the general public, including state and local governments and therefore, those entities cannot refuse, withhold, or deny accommodations, advantages, facilities, or privileges to any person based on their race or color. Equal employment opportunity, fair housing opportunity, and public accommodations cannot be denied to any person because of his/her racial group or perceived racial group, his/her race-linked characteristics (e.g., hair texture, color, facial features), or because of his/her marriage to

Jan. 4, 2013 In many cases, obesity is caused by more than just overeating and a lack of exercise. Something in the body goes haywire, causing it to store more fat and burn less energy. But what is it? Sanford-Burnham researchers have a new theory -- a protein called p62. According to a study the team published December 21 in the Journal of Clinical Investigation, when p62 is missing in fat tissue, the body's metabolic balance shifts -- inhibiting "good" brown fat, while favoring "bad" white fat. These findings indicate that p62 might make a promising target for new therapies aimed at curbing obesity. "Without p62 you're making lots of fat but not burning energy, and the body thinks it needs to store energy," said Jorge Moscat, Ph.D., Sanford- Burnham professor. "It's a double whammy." Moscat led the study with collaborators at Helmholtz Zentrum München in Germany and the University of Cincinnati. p62 and obesity Moscat's team had previously produced mice that completely lack the p62 protein everywhere in thei

The Chaos Hypertextbook™ © 1995-2007 by Glenn Elert All Rights Reserved -- Fair Use Encouraged prev | index | next Bifurcation diagram rendered with 1-D Chaos Explorer The simple logistic equation is a formula for approximating the evolution of an animal population over time. Many animal species are fertile only for a brief period during the year and the young are born in a particular season so that by the time they are ready to eat solid food it will be plentiful. For this reason, the system might be better described by a discrete difference equation than a continuous differential equation. Since not every existing animal will reproduce (a portion of them are male after all), not every female will be fertile, not every conception will be successful, and not every pregnancy will be successfully carried to term; the population increase will be some fraction of the present population. Therefore, if "An" is the number of animals this year and "An+1" is the number next year, then An+1 = rAn where "r" is the growt

From Peace Corps Wiki |Peace Corps Welcome Book| Peace Corps was invited to work in Lesotho in 1967, one year after the country gained independence from Great Britain. Nearly 1,900 Volunteers have served in Lesotho over 37 years, most being assigned to education and agriculture projects. Current programming goals are based on community development projects that accommodate placements of Volunteers in education and community health and development. Peace Corps History Main article: History of the Peace Corps in Lesotho The Peace Corps was invited to work in Lesotho in 1967. Since that time, a relatively constant number of about 95 Volunteers have served at any given time in Lesotho, except for a brief time following a political uprising in 1998. Education, agriculture, and health have been the primary Peace Corps programs here. The focus of Volunteer placement has been rural development, which mirrors the country’s 85 percent rural population demography. Volunteers serve in all 10 districts of the country. The

"It is important to control this process carefully as too many defects can deteriorate the electrical conductivity, which is the reason for the use of CNTs in the first place. Good conductivity helps in efficient charge transport and increases the power density of these devices," Bandaru added. "At the very outset, it is interesting that CNTs, which are nominally considered perfect, could be useful with so many incorporated defects," he added. The researchers think that the energy density and power density obtained through their work could be practically higher than existing capacitor configurations which suffer from problems associated with poor reliability, cost, and poor electrical characteristics. Bandaru and Hoefer hope that their research could have major implications in the area of energy storage, a pertinent topic of today. "We hope that our research will spark future interest in utilizing CNTs as electrodes in charge storage devices with greater energy and power densities," Hoefer said. While more re

In 1971 America had a currency crisis. Other nations had stopped accepting our paper dollars as payment for our debts and were demanding gold instead. The problem was that America didn't have enough gold to cover the massive debts being run up because of the war in Vietnam. What did we do? We simply defaulted on our debt by repudiating the promise to back our currency with gold. The situation was epitomized by Nixon's Treasury Secretary John Connally, when he responded to the complaints of 29 trading and banking allies: “It may be our currency, but it's your problem.” 37 years of massive budget and trade deficits later it is still our currency and it is still someone else's problem. However, every game must someday end. Eventually the costs of playing the game become so great that the benefits of not playing become attractive. The world is now approaching a point where it is being forced to make a choice. The Prisoner's dilemma is a mathematical game theory developed in 1950 by Merrill Flood and Melvin Dreshe

Forests - threats Around the world, lush tropical forests are being logged for timber and pulp, cleared to grow food, and destroyed by the impacts of climate change. Four fifths of the forest that covered almost half of the Earth's land surface eight thousand years ago have already been irreplaceably degraded or destroyed. Cattle Paths in the Amazon Every two seconds, an area of forest the size of a football pitch is lost due to logging or destructive practices. Seventy two per cent of Indonesia's intact forest landscapes and 15 per cent of the Amazon's have already been lost forever. Now the Congo's forests face the same threat. While the causes vary from region to region, they all have one thing in common: human activity. Through agriculture and logging, mining and climate change, humankind is wiping out irreplaceable forests - and the life that depends on them - at a terrifying pace. View of the Amazon from above. This 1645 hectare area has been logged to plant soy. Agri-business is responsible for massive

The first Winter Olympic Games, Chamonix 1924, had six sports on the program and 16 events. Today the number of sports has only increased by one to seven with multiple disciplines in bobsleigh, skating and skiing. At the 2014 Games in Sochi Russia - alpine parrallel team skiing, snowboard and ski slopestyle have been added meaning 98 events will be contested. Since Athens 1896, there have been many changes to the sports on the summer Olympic program. There were 26 sports contested at London 2012 and at Rio 2016 golf and rugby-7s join the program to reach 28. Aquatics, canoe/kayak, cycling, gymnastics, equestrian, volleyball and wrestling have multiple disciplines. Learn more on each sports page. A number of sports previously on the Olympic program have been dropped throughout Games history. Golf and rugby union were discontinued but have been reinstated to the Olympic program for Rio 2016. Baseball and softball were dropped after the 2008 Games.

As much as it may seem like the bodies of famous world leaders such as Vladimir Ilyich Lenin and Mao Zedong have been preserved for all eternity, their enduring physical presence is simply an illusion aided by science. Only the Venezuelan officials who have promised to preserve Hugo Chavez and display his body "for eternity" inside a glass tomb know exactly how they're going to do it. But if they were to follow procedures that are used in the United States, the technique might be rather simple: repeat embalming. "The first thing to remember about embalming as we do it in the U.S. is that it is designed to delay the natural deterioration of the body; it's not forever," said Vernie Fountain, a licensed embalmer and owner and founder of the Fountain National Academy of Professional Embalming Skills in Springfield, Missouri. So what does that mean exactly? You might want to put down your sandwich before you read on. In the U.S., most embalmers use a machine that injects fluid laced with chemicals, principally for

Globalization, Human Rights & Security Women make up a majority of the world’s poor; more than half of immigrants, refugees and casualties of armed conflicts; and they are often the first to feel the brunt of economic, political, environmental and humanitarian crises. At the same time, women are essential partners for promoting conflict resolution, reducing extremism and promoting post-conflict reconstruction and sustainable development. However, governments and international organizations often overlook the significant contributions and vital perspectives of women and girls, thereby undermining effective security policies and peace-building initiatives. Human rights advocates and security experts are calling for more efforts to invest in women, implement gender-sensitive laws and policies and ensure that women are included at decision-making tables.

The First Month of the Nazi Occupation The Germans are Coming On Friday, the 4th of July, 1941, 13 days after the German army had begun its attack on the USSR, the Germans arrived at the gates of Pinsk, which then numbered, according to German sources, 80,000 inhabitants, 35-40,000 of whom were At eleven o'clock in the morning the first German airplanes appeared in the sky. The people outside ran in panic to their homes. The peasants who had come to town for market day hurriedly returned to their villages. The Russian N.K.V.D. (The Commissariat of the Interior), who were the last of the former authorities to remain, hastily packed their belongings and sped in their cars in the direction of the bridge over the Pina River. Suddenly there was the sound of a huge explosion: the retreating Russians blew up the bridge. Several buildings on the edge of the town went up in flames, set on fire by the Russians. Then all became quiet, the silence being shattered from time to time by bursts of cannonfire. Shells flew ove

How to Help a Sick or Injured Raptor - Please note that all wild birds, including raptors are protected under state and federal laws, it is illegal to harm, harass or possess any wild bird. You are allowed to rescue a wild bird but you must get it to a permitted facility as soon as possible. The quicker the bird is in qualified care the better its chances are for release. - Raptors can be very dangerous, even sick, injured and/or young birds. They have very sharp talons and beaks! BE CAREFUL! - Please note the location where the bird was found, this information will be necessary in order to return the bird to its home once it has recovered - For baby raptors, please note the exact location it was found, mark the spot if possible. Look up into the trees to see if the nest and/or adults are there. Every attempt should be made to reunite families. - Get a box that is slightly larger than the bird. Poke lots of air holes into the sides. Place the box over the bird. Carefully slide something flat under the box in

By Robert Lucke All winter recreationalists should be aware that weather factors play a big part in avalanche activity in most all mountains. The U.S. Forest Service has some weather related tips. Wind - Even during clear weather, sustained winds of over 15 mph may cause danger to increase rapidly when loose surface snow is available for transport. Snow plumes from ridges and peaks indicate that snow is being moved onto leeward slopes. This can create dangerous situations. Leeward slopes are dangerous because wind-deposited snows add depth and may create unstable wind slabs. Windward slopes generally have less snow and the snow is compacted and usually more stable toward the leeward slopes. Storms - A high percentage of all avalanches occur shortly before, during, and after storms. Be extra cautious during these periods. Rate of Snowfall - Snow falling at one inch per hour or more increases avalanche danger rapidly. Crystal Types - Observe snow-crystal types by letting them fall on a dark ski mitt or parka sl

Ben Chou, Water Policy Analyst, Washington, D.C. Growing up in the Upstate area of South Carolina, my family and I oftentimes made the short trip to the Great Smoky Mountains, the most visited of all the national parks. We would play in the cool streams, hike on the trails, and gawk at the wildlife we encountered. Nearly 20 years later, I still recall fondly much of my time spent there. However, climate change could render those childhood memories a relic of the past for future generations and imperil the way of life for many in the Volunteer State. The Sustainable Tennessee Organization, a group of researchers from Oak Ridge National Laboratory, state universities, and the state Department of Health, recently released a new report. It summarizes current research on the potential impacts of climate change on the people, communities, economy, and natural resources of Tennessee. Here are just a few of the group’s findings: - The state’s major cities have warmed approximately 2°F since 1950. - Extreme rainfall e

Myocardial Perfusion Scan, Stress (Exercise Thallium, Stress Thallium, Cardiac Nuclear Imaging, Adenosine Thallium Scan, Cardiolite Scan) What is a stress myocardial perfusion scan? A myocardial perfusion scan is a type of nuclear medicine procedure. This means that a tiny amount of a radioactive substance, called a radionuclide (radiopharmaceutical or radioactive tracer), is used during the procedure to assist in the examination of the tissue under study. Specifically, the myocardial perfusion scan evaluates the heart’s function and blood flow. A radionuclide is a radioactive substance used as a "tracer," which means it travels through the blood stream and is taken up (absorbed) by the healthy heart muscle tissue. On the scan, the areas where the radionuclide has been absorbed will show up differently than the areas that do not absorb it (due to possible damage to the tissue from decreased or blocked blood flow). A stress myocardial perfusion scan is used to assess the blood flow to the heart muscle (myocard

FDA Drug Safety Communication: Medication errors resulting from confusion between risperidone (Risperdal) and ropinirole (Requip) [06-13-2011] The U.S. Food and Drug Administration (FDA) is alerting the public to medication error reports in which patients were given risperidone (Risperdal) instead of ropinirole (Requip) and vice versa. In some cases, patients who took the wrong medication needed to be hospitalized. The FDA determined that the factors contributing to the confusion between the two products include: - Similarities of both the brand (proprietary) and generic (established) names - Similarities of the container labels and carton packaging - Illegible handwriting on prescriptions - Overlapping product characteristics, such as the drug strengths, dosage forms, and dosing intervals. Facts about Risperidone and Ropinirole Patients who take Requip, Risperdal, or their generic equivalents are reminded to take note of the name and appearance of their medication, know why they are taking it, and to ask que

Skip to content Skip to navigation menu 26 September 2008 Primary care plays a crucial role as the front-line service of the NHS, particularly in Wales, which has some of the most disadvantaged communities in Europe. Effective, comprehensive primary care improves not only health but also quality of life. However, the provision of primary care varies greatly across the country. Rural and post-industrial areas pose very different healthcare challenges. The review by Derek Wanless identified a need for primary care investment and development to ensure sustainability of both primary and secondary care services. Currently, a lot of health care is delivered in hospitals that could and should be provided in the community, close to where people live and more cost effectively. The Welsh Assembly Government’s vision is for locally accessible services offering patients integrated services from clinical, health and social care professionals, together with services for procedures where quality is enhanced by concentrating

Embargo expired: 2/4/2013 3:00 PM EST Source Newsroom: Columbia University School of Engineering and Applied Science Newswise — New York, NY—February 4, 2013—Researchers at Columbia Engineering and Georgia Institute of Technology have published a study in the online Early Edition of Proceedings of the National Academy of Sciences (PNAS) showing—for the first time—that certain volatile organic gases can promote cloud formation in a way never considered before by atmospheric scientists. The study will be published the week of February 4, 2013. “This is the first time gases have been shown to affect cloud formation in this way,” says V. Faye McNeill, Associate Professor in Chemical Engineering at Columbia University’s Fu Foundation School for Engineering and Applied Science, and co-leader of the research team. “This is a very exciting finding that will improve our ability to model cloud formation, an important component of climate.” The research team, co-led by Athanasios Nenes, Professor & Georgia Power Faculty

GENOVA - Italy is waging war on a group of American invaders that are threatening the existence of their European peers. American grey squirrels, which were first introduced into Europe in 1948, have thrived in the parks of the northeastern region of Liguria since the 1960s. With 10-inch-long bodies, equally long tails and a weight that can reach 21 oz., American grey squirrels are bigger than European red squirrels. These strong Americans invaders steal the Europeans food and carry diseases that are lethal to locals. To defend the indigenous squirrel population, Liguria, Piemonte and Lombardia regions, as well as the Italian Environment ministry, have launched a project aimed at uprooting the estimated 300 American grey squirrels living in the Levante Genovese Park. The cost of the war against American squirrels nearly 2 million euros is partially covered by the European Union. This squirrel war has its general, Andrea Balduzzi, a professor of natural sciences at the University of Genoa. At dawn, the profess

With the U.S. presidential debates in full swing and the election just around the corner, the world is watching, wondering which way the political winds will blow. Writer Gavin Au-Yeung asked Assistant Professor Ryan Hurl to give U of T News a quick review of the American electoral system, the major political issues at stake, and why the world can't get enough of U.S. election coverage. How does the U.S. political system differ from ours? The most important difference is the significance of the separation of power. This refers to the fact that the executive in the American system doesn't depend on the confidence of the legislature to maintain power. In a parliamentary system, parties need to maintain the vote of confidence – if you lose it there'll be another election. The American system doesn't work like that; and over time it creates more individualistic forms of party organization, where it's easier for party members to depart from their party line because the electoral incentives are different. The prima

The Northwest Power and Conservation Council says more electric cars on the roads will use more power in the future. The Northwest Power and Conservation Council is increasing its previous estimates of how much power plug-in cars will need by 2030. The Council says high gas prices and better technology could drive up electric car sales. That means drivers will need more power to plug in their vehicles. On the low end of the scale, the Council estimates electric cars could use the same amount of power as roughly 80,000 homes every year. On the other hand, it may be about the same as 350,000 homes. But the Council says more power plants will not need to be built. Electric car sales have steadily increased during the first three months of this year.

The Neuquén Basin in northern Patagonia, Argentina, has long been valued for its assorted treasures. The area has been tapped for its oil and gas reserves for years, but paleontologists have scoured the area looking for something else: fossils that would provide a window to this area’s past. In November 2005, a research team described a prehistoric creature whose fossil remains they found in the Basin. Unlike anything alive today, the 135 million-year-old, 13-foot-long crocodile had the head of a meat-eating dinosaur and the tail of a fish. Landsat 7’s Enhanced Thematic Mapper Plus (ETM+) sensor captured this image of the Neuquén Basin on October 27, 2000. The Neuquén Basin is now a semiarid environment, evidenced by its earth tones ranging from beige to rust to deep brown. In the center right portion of the image, an array of tiny beige dots shows evidence of human activity—exploration for oil and gas in the form of wells. The rocks themselves, however, document the vastly different environment that existed

Kerala is known the world over as God’s Own Country for its culture, people and abundance of natural beauty. A visitor’s true intake of the geographic beauty of the land is best obtained by taking a drive through the land. Road tourism is still at its dormant stage in Kerala, although the prospects are unbounded. The proposed Hill Highway connecting Nandarapadavu in Kasargod to Parassala in Trivandrum, winding through the hilly portions of the State, stretching to a length of 1332.16 kilometers, is one important project taken in the right direction tourism wise, which would also enable fast development of the generally backward hilly regions of the state. Due to its unique topography, most of the development within the state has been happening near the eastern shoreline, which has the two National Highways and the railway lines passing through it. But for the hill terrains, the only means of transport available is roads, which on the most part, are in a pathetic condition. NATPAC (National Transportation Plan

FOLIC ACID Overview Information Folic acid is a water-soluble B vitamin. Since 1998, it has been added to cold cereals, flour, breads, pasta, bakery items, cookies, and crackers, as required by federal law. Foods that are naturally high in folic acid include leafy vegetables (such as spinach, broccoli, and lettuce), okra, asparagus, fruits (such as bananas, melons, and lemons) beans, yeast, mushrooms, meat (such as beef liver and kidney), orange juice, and tomato juice. Folic acid is used for preventing and treating low blood levels of folic acid (folic acid deficiency), as well as its complications, including “tired blood” (anemia) and the inability of the bowel to absorb nutrients properly. Folic acid is also used for other conditions commonly associated with folic acid deficiency, including ulcerative colitis, liver disease, alcoholism, and kidney dialysis. Women who are pregnant or might become pregnant take folic acid to prevent miscarriage and “neural tube defects,” birth defects such as spina bifida th

Here’s a scary thought, especially if you owe back taxes: What if the Internal Revenue Service reported your payment history to the big national credit bureaus? Unlike many other debts owed to the federal government, unpaid taxes are not reported to credit bureaus. The IRS is not allowed to directly share this information because of federal privacy laws. Of course, Congress could always change the law to allow the IRS to directly report all delinquencies to the credit bureaus. No one has proposed making this change, but last year the Senate Finance Committee did ask the General Accounting Office to look at the issue. The GAO did not make any recommendations in its report released in October, but it did list arguments for and against the idea. It also provided some hard numbers about the staggering amount of money owed to the federal treasury in unpaid taxes. As of October 2011, about $343 billion was owed in unpaid federal tax debts. That’s more than the federal deficit of $207 billion for the 2012 budget yea

On the heels of a scientific report last month saying 63 percent of world fish stocks require rebuilding, scientists at MIT have unveiled a new robot fish that's cheap to make and ripe for mass production. Actually, MIT engineers Kamal Youcef-Toumi and Pablo Valdivia Y Alvarado aren't aiming to replenish fisheries. They want their robot swimmers to be used for underwater monitoring of pipelines, sunken ships, and pollution. Since the fish are less than a foot long, they can maneuver into spaces that are too tight for most underwater autonomous vehicles (UAVs). The fish--while not as pretty as these toxin-sniffing robot carp patrolling Spanish waters--are notable for their novel design. They have fewer than 10 parts, making them low-cost, and are housed in a continuous flexible polymer casing that prevents water damage. Lacking different segments, the fish can swim more naturally, according to MIT (watch the video after the jump). A single motor in the middle initiates a wave that moves along the body and prop

The solution: Gene painting. Researchers at MetroHealth Medical Center in Cleveland, led by cardiac electrophysiologist Kevin Donahue, have identified a gene that helps hearts beat normally. They've packaged that gene inside a virus and put that virus into a clear gel that's the consistency of toothpaste. When they paint the gel onto an animal heart -- they use paintbrushes from an art supply store -- the virus with the corrective gene works its way into the heart and, within hours, the heart begins to calm down. In about two days, it's beating normally again. MetroHealth researchers are performing the open-heart procedure on animal hearts now. But they've had such good results, they're talking to the FDA about trying it in humans during heart surgery, while they still have their chests open. A particular type of abnormal heartbeat called atrial fibrillation is very common after open-heart surgery; although often temporary, it can lead to complications including stroke, longer hospital stays and even death.

(ARA) –The Clean Water Act was established 40 years ago with the goal of protecting waterways and ensuring homes and offices receive clean drinking water. As the legislation marks its 40th anniversary, water officials and water consumers alike are looking back on the accomplishments and planning for new ways to continue water quality improvements. “The Clean Water Act touches every source of water and establishes a goal for protecting our waterways and systems in the cities and communities where we live and work,” says Mike Musgrave, director of program development for MWH Global, a water-focused engineering consulting firm that has helped organizations and municipalities meet demands of the Clean Water Act. While the effects of the Clean Water Act are far-reaching, do you realize its impact on your day-to-day water usage? Whether trolling your favorite fishing spot, taking a dip in your local swimming hole or enjoying a glass of tap water, the Environmental Protection Agency and cities around the country are

to the Spiritual Growth Study on Exodus: The Journey to Freedom. Christine Keels and the Rev. Bernard Keels have provided a deep river of content to draw us through the historical journey of African American Methodists in the United States. For these modern-day successors of the ancient Hebrews whom Moses led out of slavery in Egypt, there is a river between their desert wandering and the promised land; it is the river Jordan, and those traveling to the promised land have to go through it. can be read as an ancient history of the Hebrews, showing the power of our God, whom we worship in church each Sunday. This is important. But the United States has its own Exodus story to tell, and we have not crossed over Jordan yet. Many generations have passed since our Civil War, and many have forgotten the story of how freedom was won for an enslaved people in this country. There is no annual commemoration like that of the Jewish Passover. No bread is broken, no wine is spilled, and no story is told about why "this nig

Date: October 30, 2012 Department: SMAST / Administration The proposed research will employ a combination of models and observations from ships and satellites to examine linkages between land and ocean and how these interactions affect the ocean's ability to take up CO2 from the atmosphere. The project was one of 62 proposals considered by NASA as part of its Carbon Monitoring System Science Team, which includes members from across the country. SMAST Dean Dr. Steven E. Lohrenz will personally lead the research team, which includes partners from universities in Alabama, Georgia, Mississippi and North Carolina. "The oceans absorb about one third of all the fossil fuel CO2 emitted into the atmosphere, but the contribution of coastal waters to this is still very uncertain. Carbon dioxide in the atmosphere influences climate and can alter the chemistry of the oceans in ways that may negatively impact marine organisms, but we simply don't know enough about how CO2 is being absorbed by the oceans and particularly by

Jerome David "J. D." Salinger (pronounced /?sæl?nd??r/; born January 1, 1919) is an American author, best known for his 1951 novel The Catcher in the Rye, as well as his reclusive nature. He has not published an original work since 1965 and has not been interviewed since 1980. Raised in Manhattan, Salinger began writing short stories while in secondary school, and published several stories in the early 1940s before serving in World War II. In 1948 he published the critically acclaimed story "A Perfect Day for Bananafish" in The New Yorker magazine, which became home to much of his subsequent work. In 1951 Salinger released his novel The Catcher in the Rye, an immediate popular success. His depiction of adolescent alienation and loss of innocence in the protagonist Holden Caulfield was influential, especially among adolescent readers. The novel remains widely read and controversial, selling around 250,000 copies a year. The success of The Catcher in the Rye led to public attention and scrutiny: Salinger became

Findings in Music Cognition A growing body of research suggests that music is a specifically human, rather than natural phenomenon. Increasing access to brain imaging technology along with other recent advances in neuromusical research methods has fostered significant growth in the understanding of the cognitive and neurobiological foundations of music listening and performance. Rhythm and pitch are reviewed as core perceptual elements of music. The author then explores cognitive processes that integrate these elements into larger units of musical content and meaning. Studies of the differences in perception between musicians and non-musicians suggest the ways that musical training impacts musical perception. Finally, this evolving body of knowledge about how humans perceive music suggests insights that can enhance the teaching and learning of music. Dr. Douglas C. Orzolek

Mammography is an X-ray technique used to study the breast and is used to locate any signs of breast cancer. It’s important to catch breast cancer and begin treatment as soon as possible in order for the treatment to be completely successful. Research shows that about 1 in 8 women will get breast cancer during their lives. This is more common in women who are past menopause and the risk increases as you continue to age. By the time you reach forty, mammography should be a regular part of your health care. The mammography passes low doses of X-rays through the breasts. It helps detect any growths that are small or lie deep in the breast tissue. Sometimes these growths are benign (not cancer), but others may be malignant (cancer). Mammography is a good way to find cancerous growths before they are large enough to be felt. When cancer is found in this early stage, it is easier to treat. Caught early enough, breast cancer often can be cured. There are self-exams that can also be done at home and your gynecologist

Once a normal to the surface at the point of incidence is drawn, the angle of incidence can then be determined. The light ray will then reflect in such a manner that the angle of incidence is equal to the angle of reflection. This

Mar. 11, 2004 Using satellite and other data, scientists have discovered that sea surface temperatures and sea level pressure in the North Pacific have undergone unusual changes over the last five years. These changes to the North Pacific Ocean climate system are different from those that dominated for the past 50-80 years, which has led scientists to conclude that there is more than one key to the climate of that region than previously thought. According to a study by Nicholas Bond, J.E. Overland and P. Stabeno of the National Oceanic and Atmospheric Administration (NOAA) Pacific Marine Environmental Laboratory, and M. Spillane of the University of Washington, during the last four winters from 1999-2002 (ranging from November to March) sea surface temperatures were cooler than normal along the U.S. west coast and warmer than normal in the coastal Gulf of Alaska. These conditions differ from those of the Pacific Decadal Oscillation (PDO), thought to be the primary key that causes the climate of the North Paci

The Strangest Man: The Hidden Life of Paul Dirac, Mystic of the Atom by Graham Farmelo Basic Books, 539 pp., $29.95 Why should anyone who is not a physicist be interested in Paul Dirac? Dirac is interesting for the same reasons that Einstein is interesting. Both made profound discoveries that changed our way of thinking. And both were unique human beings with strong opinions and strong passions. Besides these two major similarities, many details of their lives were curiously alike. Both won the Nobel Prize for physics, Einstein in 1921 and Dirac in 1933. Both had two children of their own and two stepchildren from a wife’s previous marriage. Both were intensely involved in the community of professional scientists in Europe when they were young. Both of them emigrated to the United States and became isolated from the American scientific community when they were old. The main difference between them is the fact that Einstein was one of the most famous people in the world while Dirac remained obscure. There are

Pick from the Past THE UMIAK is nearly extinct. Fewer than 100 survive in the wild, and only about a dozen dull, dusty specimens can be found in the museums of the world. Once its range was immense: from eastern Siberia to East Greenland. The spacious, seaworthy skin boat of the Inuit and their arctic neighbors, the umiak was the perfect boat for whaling and walrus hunting in the ice-choked, storm-haunted seas of the north. The boats size permitted trade and migration, linking continents and cultures. After the umiak was invented, wrote anthropologist Dorothy Jean Ray, the [Bering] Strait became an intercontinental highway, its coastal fringes occupied by peoples who had more or less the same way of life. Today the umiak is used only in a few localities on the coasts of Alaska and Siberia. Capt. Frederick W. Beechey of Britains Royal Navy saw umiaks in 1826 on Little Diomede Island in the Bering Strait and took a sailors delight in these craft, which were both light and pliable and very safe and durable.

Nova Scotia is one of Canada’s three Maritime provinces and is the most populous province of the four in Atlantic Canada. Located almost exactly halfway between the Equator and the North Pole, its provincial capital is Halifax. Nova Scotia is the second-smallest province in Canada with an area of 55,284 square kilometres (21,300 sq mi), including Cape Breton and some 3,800 coastal islands. As of 2011, the population was 921,727, making Nova Scotia the second-most-densely populated province in Canada. Nova Scotia was already home to the Mi’kmaq people when French colonists established Port Royal, Nova Scotia, the first permanent European settlement in North America north of Florida in 1605. Almost one hundred and fifty years later, the first English and German settlers arrived with the founding of Halifax (1749). The first Scottish migration was on the Hector (1773) and then the first Black migration happened after the American Revolution (1783). Despite the diversity of the cultural heritage of Nova Scotia, m

Daycare May Benefit Moms Suffering from Depression -- and Their Kids Enrolling the children of depressed moms in daycare can have emotional, psychological, and social benefits -- even when the toddlers get just half a day of care each week, reports CNN. The study of Australian moms was relatively small -- only 400 families -- but it's the first of its kind to show that children who get even a few hours of daycare a week when their moms are suffering from depression had fewer behavioral problems at the age of five. Researchers theorize that giving the moms a short break helps them be better parents when they are with their kids, and that it can also help boost their energy levels -- "It's tiring parenting a child all day, and if you're depressed even more tiring," explains one professor -- and that the kids benefit from the socialization at day care, which they may not get if mom is too depressed to make playdates and Mommy and Me a priority. "Toddlerhood is a time when social interactions are very important d

UN Convention Against Torture – Article 10 - Each State Party shall ensure that education and information regarding the prohibition against torture are fully included in the training of law enforcement personnel, civil or military, medical personnel, public officials and other persons who may be involved in the custody, interrogation or treatment of any individual subjected to any form of arrest, detention or imprisonment. - Each State Party shall include this prohibition in the rules or instructions issued in regard to the duties and functions of any such persons. During the Troubles in Northern Ireland, the British Armed Forces and the Royal Ulster Constabulary were using the ‘five techniques’ (wall standing, hooding, subjection to noise, sleep deprivation and food and drink deprivation) as a precursor to interrogation of suspected terrorists. Following complaints and an inquiry, Lord Chief Justice Lord Parker’s report stated that such practices were illegal under both the Geneva Conventions and domestic la

Alright, so a full-blown, Google-sanctioned version of "Google Earth live" is still probably 10-20 years away. But at least one company (other than Google) is pushing to make live, HD video of Earth a reality much, much sooner than that. The company is called UrtheCast (pronounced "Earthcast"), and according to Google Creative Sandbox, their plan is to mount two cameras on the International Space Station that will not only stream live content at resolutions as low as one meter per pixel, but also "create a video version of Google Earth with the video playback and search functionality of YouTube." Granted, UrtheCast's two- cam setup has its limitations. Google Earth Blog runs through a few of them: 1) For any particular orbit, you may not be able to view the desired location (too far over the horizon, too much of an angle). You might a have to wait dozens of orbits to get over that spot. 2) Daylight - you have to be over the location at the right time of day. 3) Weather - too many variables to count a) clouds b

Slick gadgets and cool software? Or, paper and pen? What tools do you really need to develop effective training materials? What technologies are available and how should the technology be used? First, let's define. What is multimedia? It's the text, graphics, animations, audio and video that comprises your course or training content, integrated and presented in a way that will help learners better understand the material. Why multimedia? Research shows that students learn better if the content is presented in a variety of formats, stimulating multiple senses. Presenting content graphically or animating text material with audio and video not only helps to address the needs of students with different learning styles, it also creates a more engaging and interactive learning environment. Now, about the technology. We acknowledge that trying to keep up with all the new technology can be quite a challenge, especially when there is no free time in your schedule. That's where we can help. We can help you decide what

|Next: Creating the License Up: Freeing the Source Previous: Freeing the Source| The body of Communicator source code at Netscape was called ``Mozilla.'' Mozilla was a term initially created by Jamie Zawinsky and company during the development of Navigator. The team was working at a similarly frantic pace to create a beast vastly more powerful than Mosaic, and the word became the official code name for Navigator. Later the big green dinosaur became an inside joke, then a company mascot, and finally a public symbol. Now the name came into use as the generic term referring to the open-source web browsers derived from the source code of Netscape Navigator. The move was on to ``Free the Lizard.'' There was an amazing amount to be done to make the code ready for prime time. As issues surfaced, they separated themselves into categories and were claimed. The next three months were devoted to resolving issues at the fanatical pace that Netscapers knew well. One of the largest issues was the disposition of the third-p

|LCD TV, flat screen TV| |Friday, 19 January 2007| A liquid crystal display (LCD) is a flat screen display with property of low power consumption, and decreased significantly in either occupied space or weight in comparison with a conventional cathode ray tube (CRT) and without curve surface as a CRT display has. A liquid crystal display device is a display device that comprises a liquid crystal sealed between two opposing substrates and that uses electrical stimulus for optical switching by exploiting the electro-optical anisotropy of a liquid crystal. An LCD displays an image containing information by adjusting the arrangement of the liquid crystal. The liquid crystal changes a transmissivity of light passing through the liquid crystal according to an electric field applied to the liquid crystal. The liquid crystal display changes the optical properties of liquid crystal layers that pass light according to the molecular arrangement, and uses the modulation of the light of the liquid crystal cells.

DALLAS (AP) — Nearly two-thirds of the state's 254 counties have been declared federal primary natural disaster areas from drought and heat in a step toward providing help. The U.S. Department of Agriculture on Wednesday included 157 Texas counties in the 2013 designation. Qualified farm operators are eligible for low-interest emergency loans. National Climate Data Center numbers released Tuesday indicated 2011 and 2012 were the state's warmest two-year span in more than 100 years. Texas had its driest year ever in 2011. Agriculture Secretary Tom Vilsack overall designated 597 counties in 14 states as primary natural disaster areas due to lingering drought and hot weather.

Church of Nativity - Birth Place of Jesus Christ The Church of the Nativity in the heart of Bethlehem marks one of Christianity's most sacred sites - the birthplace of Christ. Situated on Manger Square 8 kilometres (5 miles) from Jerusalem, the church is built over a grotto where the Virgin Mary is said to have given birth to Jesus. The church's large fortress-like exterior stands as a testament to its turbulent history. For centuries, it was one of the most fought over holy places. It was seized and defended by a succession of armies - including Muslim and Crusader forces. It is controlled jointly by three Christian denominations - the Armenian Church, the Roman Catholic Church and the Greek Orthodox Church. - The Grotto of the Nativity contains the manger that is believed to be the place where the baby Jesus was laid after he was born. The grotto is encased in white marble. - The site of the birth is marked by a 14-point star on a marble stone. - The High Altar standing above the Grotto. The site has been v

FOR IMMEDIATE RELEASE HONORING OLD GLORY ON FLAG June 14 Marks the 230th Birthday of the MOUNT LAUREL, NJ, JUNE 11, 2007 – The Flag Manufacturers Association of America (FMAA) proudly celebrates the 230th birthday of the U.S. flag on Flag Day, June 14, and encourages all Americans to join in the celebration and honor our nation’s great symbol by flying their U.S. flag. The national flag we are familiar with today was adopted 4, 1960 following the inclusion of United States of . This flag was a descendant of an original flag – the flag that was born within a year of American Independence.

12.01.2013, ID: 24173 Grossmünster in Zurich is the largest cathedral in the most populous Swiss city. Grossmünster was built by order of Emperor Charlemagne. Regensburg Catedral of St. Peter is the religious symbol of the city. St. Peter's cathedral in Regensburg was completed in 1634. The church of St. Anton is located in the Romanian capital Bucharest. The beautiful tower of St. Anton’s Church was erected in the reign of Grigore Ghica. St. Peter's Basilica is located on the St. Peter Square in Rome. St. Peter's Basilica until recently was considered the largest church in the world. Berlin Cathedral, known as the Berliner Dom is among the spectacular symbols of Berlin. Berlin Cathedral is about 114 meters long and 73 meters wide. Sistine Chapel is part of the Catholic complex of the Vatican. Sistine Chapel was built between 1473 and 1484, by order of Pope Sistus IV. The foundations of St. Stephen cathedral were laid back in 1147. Stefansdom is named after St. Stephen, who is also the patron of the cathedral

Tiny parasitic worms that cause chronic illness in millions of sub-Saharan Africans may increase their chances of contracting HIV, according to a new report. This study comes just a week after another set of researchers announced a different theory regarding a factor that could increase Africans’ susceptibility to the HIV virus, hypothesizing that a genetic variant found in people of African descent raises the risk of HIV infection. In the latest study, researchers infected monkeys with the worms that cause schistosomiasis, and then injected them with a form of the HIV virus. They found that much lower amounts of the virus were necessary to give AIDS to the monkeys that had the parasitic worms, as compared to parasite-free monkeys. The phenomenon… needs to be verified in humans. But with primates a generally reliable model of AIDS pathology, it could help explain why sub-Saharan Africa, where 160 million people are infected with schistosomiasis, has 10% of the world’s population and 62% of its AIDS cases [Wir

The heliograph had some powerful advantages. It allowed long distance communication without a fixed infrastructure, though it could also be linked to make a fixed network extending over hundreds of miles, as in the fort-to-fort network used in the Geronimo campaign. It was highly portable, required no power source, and was relatively secure since it was invisible to those not near the axis of operation. However, anyone in the beam with the correct knowledge could intercept signals without being detected. In the Boer war, where both sides used heliographs, tubes were sometimes used to decrease the dispersion of the beam. The distance that heliograph signals could be seen depended on the clarity of the sky and the size of the mirrors used. A clear line of sight was required, and since the earth's surface is curved, the highest convenient points were used. Under ordinary conditions, a flash could be seen 30 miles (48 km) with the naked eye, and much farther with a telescope. The maximum range was considered to b

Public Domain The Chinese Algae Eater is a workhorse when it comes to its job... eating algae! The Chinese Algae Eater Gyrinocheilus aymonieri is a one of the best known aquarium fish. It is found in large areas of Southeast Asia and southern parts of China. It was first exported to Germany in 1956 for the aquarium trade, but In its native countries it is used as a food fish. This fish is very much desired by many aquarists. Though not the most beautiful of fishes, it is mainly appreciated for its ability to keep the aquarium free of algae. It does a great job at that when it's a youngster but as it matures its diet preferences begin to change. It will start looking for a meatier food source, like small crustaceans and even the slime coating of other fish, and it also starts enjoying the easier foods supplied by its keeper.

European Painting before 1900, Johnson Collection Ballet from an Opera Box Hilaire-Germain-Edgar Degas, French, 1834 - 1917 Pastel on paper Currently not on view Cat. 969John G. Johnson Collection, 1917 LabelThe setting for this pastel is the Palais Garnier Opéra House, where you can still attend performances today. The Palais Garnier is famous for its opulent and luxurious interior. However, instead of focusing on this richly ornamented space, Edgar Degas concentrates on the colorful dancers, the theatrical lighting, and the audience's overwhelming visual experience. A finely dressed woman rests her arm on a balcony railing and looks over her shoulder to watch the performance from a box seat above the stage. A dancer in a bright yellow and orange costume is taking a bow. Degas portrays the spectacle from a disorienting point of view, cutting off the central figures with other figures or with the edges of the picture frame. He loved using pastel because he could scribble lines but also use his fingers to smud

Thiamine (Vitamin B1) How does Thiamine (vitamin B1) work? Thiamine is required by our bodies to properly use carbohydrates. Are there safety concerns? Thiamine is safe for most adults. Rarely, side effects such as skin irritation or other allergic reactions can happen. Thiamine is likely safe for pregnant or breast-feeding women when taken in the recommended amount of 1.4 mg daily. Thiamine might not properly enter the body in some people who have liver problems, drink lots of alcohol, or have other conditions. Dosing considerations for Thiamine (vitamin B1). The following doses have been studied in scientific research: - For adults with somewhat low levels of thiamine in their body (mild thiamine deficiency): the usual dose of thiamine is 5-30 mg daily in either a single dose or divided doses for one month. The typical dose for severe deficiency can be up to 300 mg per day. - For reducing the risk of getting cataracts: a daily dietary intake of approximately 10 mg of thiamine. As a dietary supplement in adu

Check against delivery Nairobi, 5 August 1999 - The commemoration of the International Day of the World's Indigenous People every year is a day to focus our attention on the unique circumstances of indigenous societies throughout the world and the importance of indigenous cultures to the global community. It is a day to foster greater appreciation, understanding and respect for the cultural, political, social, religious and economic rights of the world's indigenous people. An estimated 300 million indigenous people inhabit more than 70 countries worldwide. They live in a wide range of ecosystems -from polar regions and deserts to the savannahs and tropical forests. There is a remarkable overlap between the global mappings of world's areas of biological megadiversity and areas of high cultural and linguistic diversity. Unfortunately, these areas of biological megadiversity are the ones in which biodiversity loss has been the most dramatic. These areas host the world's highest concentrations of linguistically a

Here a child paints, cooks, waters the plants, washes dishes and plays with materials that develop fine and gross motor coordination. Special activities have been designed to stimulate a child’s visual, auditory, tactile, smelling and tasting senses. Our program is distinguished by the way in which we approach each child with respect. We believe in assisting the child in her drive towards self-sufficiency. Our toddlers move toward increasing independence with activities that revolve around self-care and food preparation. Setting the table, baking bread, cutting fruit for snack and cleaning the dishes help our toddlers to feel a sense of pride. They feel like their contributions make a difference. Children who act upon the

|Updated: 1/31 6:39 pm ||Published: 1/31 3:46 pm More than 20 million Americans, both men and women, have some type of thyroid disorder. Doctors say one myth about the thyroid is that only women get thyroid disease. The thyroid is a butterfly-shaped gland in your neck. It may be small but plays a big role in major body functions like metabolism. The most common thyroid condition is underactive thyroid. This is where the gland is not producing enough thyroid hormone. Other thyroid problems include overactive thyroid, enlarged thyroid, thyroid nodules or cancer. Dr. Hatipoglu says some people fear that a thyroid nodule or growth always means cancer but that's not the case. Betul Hatipoglu, M.D says, "When you have a growth it doesn't mean you have a thyroid cancer, indeed 90-95% of those are benign but you could see what you have and if needed a biopsy can be done or you can even have it removed." If you suspect a problem with your thyroid or you're just not feeling 'right,' ask your doctor to screen for thyroi

The musée des impressionnismes in Giverny, a village in Normandy, is dedicated to the history of Impressionism and its continuation in the Giverny art colony and along the Valley of the River Seine. Giverny, land of artists Claude Monet moved to Giverny in 1883. Although he never encouraged other artists to follow him, the village soon attracted a circle of Americans eager to put the principles of Impressionism into practice at the heart of the Norman landscape. The musée des impressionnismes Founded by Daniel J. Terra in 1992, the musée d’art américain Giverny generated an unprecedented stream of exhibitions, publications, conferences, lectures, and residencies for art historians and artists on the theme of American art, during its sixteen years of existence. In 2009, a partnership was signed between the Terra Foundation for American Art, the Conseil général de l’Eure, the Conseil régional de Haute-Normandie, the Conseil général de la Seine-Maritime, the Communauté d’Agglomération des Portes de l’Eure, the M

Zookeepers across the United States and Canada are experimenting a new program with orangutans. It has been discovered that the apes are very fond of iPads. 12 zoos across the nation are currently involved with the program which give orangutans enrichment time with the tablet, twice a week. The time varies based on the attention span of the ape but it generally ranges from 15 minutes to a half an hour. Generally, orangutans enjoy interactive children apps based on painting, music and memory games. Zookeepers hope the iPads could help to break barriers of communication with orangutans, similar to how communication apps assist with the autistic. Orangutan Outreach, the New York City- based non-profit that runs the program was founded by Richard Zimmerman. Zimmerman told Reuters in an interview: "Let's say an orangutan has a toothache. He or she would be able to then tap on the iPad on a picture of a tooth and communicate it that way". The program is planning to expand to zoos of other nations like Japan and New

My nephew is preparing for a $4$-th grade state test. They need to learn topics like reflection about $x$ or $y$-axis of a point( say $(3,5)$ reflected about the $y$-axis). I tried to explain but he's not getting it. He's smart, but very distracted. How can I explain in an intuitive way?

|Intensive Vegetable Gardening for Profit and Self-Sufficiency (Peace Corps, 1978, 158 p.)| In this book we have presented the basic knowledge needed to do intensive vegetable growing. The most important part of intensive vegetable production is soil preparation. In intensive gardening the idea is to increase the number of plants that a given area of soil will support. There are two ways this can be accomplished: by increasing the depth of the root zone (double-digging) and by increasing the fertility of the soil. If the farmer or gardener follows the intensive planting chart and plants many plants very close together without giving due attention to the soil fertility the result will be poor yields. The intensive planting methods must be combined with intensive soil building. Again we emphasize the importance of the soil. To get the most from this book the farmer-gardener should spend the time it takes to really understand the chapters on soils; soil fertility, fertilizers, composting, and soil preparation. T

district salt bombay KOLABA, a district of the Bombay Presidency, India, lying between 17° 52' and 18° 50' N. lat., and between 73° 7' and 73° 42' E. long. It is bounded on the N. by Bombay harbour and Thana district, on the E. by Poona and Shthra, on the S. by Ratnhgiri and Janjira state, and on the W. by the Arabian Sea. Lying between the S diyadri range and the sea, Kolaba district abounds in hills, some being spurs of considerable regularity and height, running at right angles to the main range, whilst others are isolated peaks or lofty detached ridges. The sea frontage, of about 20 miles, is throughout the greater part of its length fringed by a belt of cocoa-nut and betel-nut palms. Behind this belt lies a stretch of flat country devoted to rice cultivation. In many places along the banks of the salt-water creeks there are extensive tracts of salt marsh land, some of them reclaimed, some still subject to tidal inundation, and others set apart for the manufacture of salt. The district is traversed by a f

What is lung cancer? - Small cell lung cancer (15-20%) are characterized by very rapid growth. In this disease, a surgical cure is rarely successful. - Non-small cell lung cancer to grow more slowly, with localized disease, the surgery has a very high priority. Worldwide, each year about one million people from lung cancer. 90% of sufferers die from this tumor. Thus, lung cancer is the most common fatal cancer among the men. For women, this cancer behind breast and colorectal cancer ranks third. In Austria, of which about 3500 patients / year are affected. 85% of the tumors are due to smoking, only 3-5% on secondhand smoke. With the number of cigarettes smoked directly increases the risk of developing lung cancer. At 20-40 cigarettes, the risk is already increased 15-fold. Worldwide there are approximately 1.1 billion smokers, representing a sixth of world population, it will be 5,500 billion cigarettes / year implemented. In Europe, continues to increase in the proportion of smokers has noted (1995: 34% of t

Do you feel that you don’t have as much energy as you would like? If so, you have company. Fatigue is one of the most common complaints that people bring to their physicians. It seems that almost everyone today feels low-energy, stressed, and worn out much of the time. The body was not designed for a sedentary life. While today most of us might consider one hour of exercise daily to be ideal, in the past, eight hours of daily exercise was not uncommon. Our ancestors lived much of their lives outdoors and walked many miles every day. Today, we live indoors, sit in chairs, and seldom walk more than a mile. Not only that, instead of peaceful outdoor surroundings, we live in a fast-paced, noisy world that interrupts us constantly with its demands and requires that we multitask our way through nerve- frazzling challenges. This way of life simply violates the body’s design principles. Furthermore, with the invention of the electric light, the body’s normal sleep habits were replaced by progressively longer periods o

The tragic events in Japan have evoked a large scale international relief effort as the nation continues to deal with the enormity of the disaster. World-wide, maritime nations have been quick to respond and ships of all types have been deployed off the coast of Japan, providing humanitarian assistance to victims of the devastating earthquake and tsunami. Australian- built ships are among this number, playing their own part in the relief effort. Both Aomori on Honshu and Hakodate on Hokkaido, the traditional home ports for Incat-built 367.5-ft catamaran Natchan World, have been hectic. The Hokkaido government has been sending supply and personnel to the region and scenes at the ferry terminal there revealed the scale of the operation to move freight across Tsugaru Strait for onward travel to the worst affected areas. The Natchan World has been operating for the Japanese Self-Defense Forces, making three round trips per day to transport soldiers and their vehicles. Her role is the latest humanitarian deployment

The amount of carbon dioxide in the earth's atmosphere is increasing, mainly because of the burning of fossil fuels and deforestation, according to the World Meteorological Organization. That means that the planet's oceans, natural carbon storage facilities, are absorbing more and more of the gas, which makes them more acidic. That in turn makes them increasingly hostile environments for the snails. "Although the upwelling sites are natural phenomena that occur throughout the Southern Ocean, instances where they bring the 'saturation horizon' above 200m will become more frequent as ocean acidification intensifies in the coming years," said Geraint Tarling, another of the study's authors. The corrosion of the sea butterflies shells doesn't necessarily kill them outright, according to Tarling, who works at the British Antarctic Survey, a polar scientific research body. "However it may increase their vulnerability to predation and infection consequently having an impact to other parts of the food web," he said.

Narrator: This is Science Today. Planets discovered outside our solar system were found to have an elliptical orbit, rather than the circular orbit of our own planets. Geoff Marcy, a professor of astronomy at the University of California, Berkeley, says this makes astronomers wonder if circular orbits are necessary for the evolution of advanced life. Marcy: If instead, the Earth were residing in an elliptical orbit, then of course the Earth would get carried close to the sun and far from the sun and close to sun, alternately heating up the water to steam and the other half of the time, freezing the water on the Earth into ice. And of course, that would not bode well for the quiescent evolution of microbiology and life in general. Narrator: Marcy says their results are a bit scary for researchers looking for extra-terrestrial Marcy: But I try to assure them they should not be scared - only five percent of the stars we've looked at have Jupiters. And although those Jupiters are in elliptical motion, the other n

Definition of Autism May Change Recently, the development of the "spectrum" of autism, specifically related disorders like Asperger syndrome and ADHD, has led to the expansion of health and educational services for millions of American children and their families. However, a new study by the American Psychiatric Association may cause that to change. The group of experts is working on the fifth edition of its Diagnostic and Statistical Manual of Mental Disorders, the main book used by psychologists and psychiatrists to diagnose psychological disorders in patients. One of the major changes being review by a panel is the definition of autism. From the New York Times: The definition is under review by an expert panel appointed by the American Psychiatric Association, which is completing work on the fifth edition of its Diagnostic and Statistical Manual of Mental Disorders. The D.S.M, as the manual is known, is the standard reference for mental disorders, driving research, treatment and insurance decisions. The st

Book Description: Talking about global environmental issues need not be an exercise in gloom, doom, and individual sacrifice—as Michael Carolan ably demonstrates in this introduction to environmental sociology.Society and the Environment examines today’s environmental controversies within a socio- organizational context. After outlining the contours of “pragmatic environmentalism,” Carolan explores the material world: air, water, biodiversity, and trash. He considers the pressures that exist where ecology and society collide, such as population growth and its associated increased demands for food and energy. Finally, he drills into the social/structural dynamics—including political economy and the international legal system—that create ongoing momentum for environmental ills.This interdisciplinary text features a three-part structure in each chapter that covers “fast facts” about the issue at hand, examines its wide-ranging implications, and offers pragmatic consideration of possible real-world solu

World Day of Remembrance for Road Traffic Victims The World Day of Remembrance for Road Traffic Victims was started by RoadPeace in 1993. Since then it has been observed and promoted worldwide by several NGOs, including the European Federation of Road Traffic Victims (FEVR) and its associated organizations. On 26 October 2005, the United Nations endorsed it as a global day to be observed every third Sunday in November each year, making it a major advocacy day for road traffic injury prevention. WHO and the United Nations Road Safety Collaboration encourage governments and NGOs around the world to commemorate this day.

According to trendspotter Springwise, the Life Box can be made to virtually any dimension and used by consumers and companies alike to package or ship goods. What sets the Life Box apart, however, is that within its corrugations are hundreds of tree seeds and thousands of spores of beneficial mycorrhizal fungi. How it works: Once a consumer removes whatever was shipped inside their box, they can tear it up, plant the pieces and water them. In about two months, tree seedlings will emerge, nurtured by the mycorrhizal fungi. In about two years, the young trees can be planted in the ground where they’ll ultimately reside. Birches, alders, pines, hemlocks and cedars are among the tree species represented, a quarter of which will survive in 90 percent of the continental United States. The Life Box company, which is based in Olympia, Wash., estimates that one tree from the hundreds of seeds in each box will survive for 30 years, allowing one ton of carbon to be sequestered. Those who planted them, meanwhile, can vis

Park Hill Meeting House National Register Nomination Information: The Park Hill Meeting House is a two-story rectangular wooden building with a gable roof, a square tower on the front (south) elevation, and a shallow entrance portico. The facade of the building is five bays wide, and the middle three bays are embraced by the portico. Supported on two pairs of attenuated and unfluted columns set at the right and left extremities of the entablature, this portico has a Doric frieze, a delicately moulded cornice, and a triangular pediment with a pitch equal to that of the roof of the main building. Each triglyph in the portico frieze has a row of drilled holes along its upper edge, just above the glyphs, in addition to the usual guttae along the bottom. The raking cornices of both the pediment and the main building have narrow friezes enriched with an applied guilloche. The flush-boarded tympanum has an elliptical window with radiating tracery, embellished with an enframement of applied window foliage. Beneath th

What Are Antioxidants? | Types of Antioxidants | The Link to Cancer, Heart Disease, and Aging | Other Conditions | What Does This Mean to You? In the 1990s, "antioxidants" became famous as the nutritional equivalent of the fountain of youth. Even doctors jumped on the bandwagon. Increasing your intake of vitamin E, beta-carotene, and was touted as an easy and painless way to prevent heart disease, vision problems, arthritis, and practically every other illness. Unfortunately, an accumulating body of research has tended to put the damper on this excitement. It now appears that antioxidant proponents had jumped the gun; in fact, these supplements may have little benefit for these purposes. Worse still, some may even risk of cancer and heart disease. What Are Antioxidants? Antioxidants are chemical substances naturally found in foods. They function as a protective "shield" against harmful, unstable molecules known as "free radicals." Free radicals are produced throughout the body as a result of normal body funct

WASHINGTON (AP) -- More bad news about Americans' waistlines: They're only going to get bigger. Already, about a third of people are obese. By 2030, it is estimated 42 percent of the population will be. The latest government data show that obesity is leveling off after big rises in earlier decades. But the new study finds even small continuing rises will add up. Duke University researchers predict that by 2030, 11 percent of people will be severely obese, roughly 100 pounds or more overweight. That's double today's rate. The obesity epidemic is fueling diabetes, heart disease and other ailments -- and adds significantly to the nation's rising health care bill.

Pick disease is a rare form of dementia that is similar to Alzheimer disease , except that it tends to affect only certain areas of the brain. Semantic dementia; Dementia - semantic; Frontotemporal dementia; Arnold Pick disease Causes, incidence, and risk factors People with Pick disease have abnormal substances (called Pick bodies and Pick cells) inside nerve cells in the damaged areas of the brain. Pick bodies and Pick cells contain an abnormal form of a protein called tau. This protein is found in all nerve cells. But some people with Pick disease have an abnormal amount or type of this protein. The exact cause of the abnormal form of the protein is unknown. Many different abnormal genes have been found that can cause Pick disease. Some cases of Pick disease are passed down in families. Pick disease is rare. It can occur in people as young as 20. But it usually begins between ages 40 and 60. The average age at which it begins is 54. The disease gets worse slowly. Tissues in the temporal and frontal lobes o

Very little reference has been made in this guide to the important aspects of if and when it is worth making an investment in a more energy-efficient technology. The great differences between countries and regions in the prices of engines, fuel and skilled labour make it meaningless to present quantitative financial guidelines. However, the following basic calculation should assist a vessel operator in investment decisions. It should be noted that the method is a quick approximation; if a large investment is being considered, a more detailed financial analysis is necessary. Total cash expenditure should be calculated by summing the purchase price, installation cost, any net lost earnings plus the additional annual maintenance cost incurred by the new investment. The net lost earnings should be estimated from the number of days the vessel will be out of service multiplied by the owner's normal net earnings (after the deduction of costs and crew share) from the vessel per day. The money to be invested could hav

Author: W. Patrick McCray Hardcover: 324 pages When the Soviets launched Sputnik in 1957, thousands of ordinary people across the globe seized the opportunity to participate in the start of the Space Age. Known as the "Moonwatchers," these largely forgotten citizen-scientists helped professional astronomers by providing critical and otherwise unavailable information about the first satellites. In Keep Watching the Skies!, Patrick McCray tells the story of this network of pioneers who, fueled by civic pride and exhilarated by space exploration, took part in the twentieth century's biggest scientific endeavor. Around the world, thousands of teenagers, homemakers, teachers, amateur astronomers, and other citizens joined Moonwatch teams. Despite their diverse backgrounds and nationalities, they shared a remarkable faith in the transformative power of science--a faith inspired by the Cold War culture in which they lived. Against the backdrop of the space race and technological advancement, ordinary people develope

On my road trip to Michigan, I visited Library Park in Elk Rapids. The Park is on the shores of Lake Michigan, with a beach, a harbor and a Jetty. At the end of the jetty were a few clumps of beach grass, bushes and a short willow. Such a harsh habitat does not teem with insect diversity, but an entomologist can intensively search the few available resources. On the willow, I found a single gypsy moth caterpillar. How did it arrive? The willow was hundreds of meters from the nearest tree. Gypsy moth females are flightless and lay eggs in clusters. It is unlikely that a female gypsy moth laid a single egg on the bush. The egg could have been part of a mass laid on a piece of wood that drifted to the jetty.Possibly the caterpillar traveled by air. Gypsy moth larvae can spin down from trees on silken thread and catch a ride on the wind. If this happened, this single larva was lucky enough to land on the only possible plant that could support it before it was blown into the miles of the watery death of nearby Lak

Intuitive Language Construction was developed after looking at current products on the market and listening to feedback from users. The one thing we heard over and over is that they wanted a program that was fun, easy, completely integrated, and that included the following components: In this post we are going to discuss the fourth component of Intuitive Language Construction…Culture. This is another big difference in the Intuitive Language Construction methodology. Mango integrates cultural notes and tips into every lesson, ensuring our students develop an understanding for the expectations, traditions, and etiquette of the people with whom they want to communicate. Most language learning systems simply ignore culture, but at Mango we think it really is critical to a student’s success in a foreign country. For example, imagine you didn’t understand the difference between formal and informal greetings. You wouldn’t want to walk into a meeting with your new boss and exclaim, “Hey Dude. What’s up?” It would be
