...Potomac Horse Fever is said to be transmitted by horses accidentally ingesting infected small aquatic flies, primarily May flies and Caddis flies that are infected with Neorickettsia risticii by consuming the larvae of infected snails. Other cases have shown that any aquatic life that carries the larvae and is ingested by the horse can transmit the illness. When the bacteria has been ingested, it starts to infect the cells lining the horses gastrointestinal tract and the mucosal cells of the large colon. This is what causes the inflammation, “colitis”, impaired absorption by the colon, and diarrhea. The fever in most cases are due to the body’s immune response to the infection. The incubation period which means, the time during which a disease establishes itself in the body. During this time the animal is infected with Potomac Horse Fever, but does not show clinical signs yet. The incubation period for Potomac Horse Fever is typically 3-9 days. Horses may start to show a fever, depression and possibly laminitis on day 5 and diarrhea about day 14 post...

...Charlinne Rivera Professor Clark ENC 1101 Research Paper 7 August 2012 Work Count: 1,227 The Unexposed Dangers of Blood Transfusions Blood is not considered the “fluid of life” without valid reason. This essential liquid is circulated throughout the human body within veins, capillaries and arteries to our heart, where it is cleaned from contaminants and waste products, then replenished with nutrients and oxygen needed to maintain life. That is the way the human body system nourishes its cells. Blood provides the necessary nutrients to our cells to keep them alive. When this process is compromised by chronic blood loss, trauma, clotting abnormalities (hemophilia, anemia, etc.), the most common treatment is the use of blood transfusions. How wise would it be to consider all of the risk factors involved with blood transfusions before making a decision to utilize one? “There is increasing evidence that blood transfusions are dangerous and often unnecessary” (Hupston, “Quality Blood Transfusion Alternatives” 1). According to the article “Blood Transfusions- Risks”, published by the Mayo Foundation Medical Education and Research (MFMER), several risks are associated with blood transfusions. Included are the possibilities of getting an allergic reaction, even when the two blood types are compatible. Such reaction can cause from hives and itching to greater problems pertaining to breathing problems and blood pressure, tachycardia, vomiting, anxiety and fever. If a reaction of...

...Climate Change: Global Warming In April 9th of 2010, Marisa Marcavillaca—a farmer and indigenous women’s organizer from Peru— went to The Capitol Hill to tell her powerful story. Her words were quoted by Al Gore in one of his speeches. She said through a translator: “We are very concerned, in my community, [and] in my country, about global climate change. Nature is disrupted. We are seeing the impacts on a daily basis. We are losing our lands, water is disappearing, it rains when it shouldn’t rain, and we have freezing temperatures, when we shouldn’t have freezing temperatures. Also, warmer temperatures in our farming area have spurred plant diseases, and the quality of agricultural seeds has degenerated cutting into local women’s ability to earn a living. Because our yields are down, it is difficult to feed our children.” (Jaime Baily 14). Climate change has become a very contested and debated matter. Some scientists say that the earth is warming; skeptics contend that it is cooling. Glaciologists say that the polar ice on earth is melting, and skeptics say that Antarctic ice is growing. Skeptics-that have also concluded that the earth is warming-point out that the earth has gone through many such warming periods (interglacials or periods of desertification) in between cooling periods and that these are natural cycles. But the long-running debate over whether or not global warming is anthropogenic is arriving to its end. Not only it is caused by man,...

Natural History Habitat and Range Range Gray wolves were common in North America, until the in the 1930's when rewards for hunting these animals were handed out because they attacked farmers' herds, and almost became exterminated. But since the reintroduction of wolves in 1995, their range has been reduced to Canada, Alaska, the Great Lakes, northern Rockies and Pacific Northwest. Habitat Gray wolves require large areas of contiguous habitat that can include forests and mountainous terrain, and must have sufficient access to prey, protection from excessive persecution, and areas for denning and taking shelter.

...Bacteria |I | |INTRODUCTION | Bacteria, one-celled organisms visible only through a microscope. Bacteria live all around us and within us. The air is filled with bacteria, and they have even entered outer space in spacecraft. Bacteria live in the deepest parts of the ocean and deep within Earth. They are in the soil, in our food, and on plants and animals. Even our bodies are home to many different kinds of bacteria. Our lives are closely intertwined with theirs, and the health of our planet depends very much on their activities. Bacterial cells are so small that scientists measure them in units called micrometers (µm). One micrometer equals a millionth of a meter (0.0000001 m or about 0.000039 in), and an average bacterium is about one micrometer long. Hundreds of thousands of bacteria would fit on a rounded dot made by a pencil. Bacteria lack a true nucleus, a feature that distinguishes them from plant and animal cells. In plants and animals the saclike nucleus carries genetic material in the form of deoxyribonucleic acid (DNA). Bacteria also have DNA but it floats within the cell, usually in a loop or coil. A tough but resilient protective shell surrounds the bacterial cell. Biologists classify all life forms as either prokaryotes or eukaryotes. Prokaryotes are simple, single-celled organisms like bacteria. They lack a defined nucleus of the sort found in plant and animal cells. More complex organisms, including all plants and animals, whose cells have a...

...Dorie Love-Ashby P. Elmore Composition II 1302-7420 5/25/11 FAULKNER Faulkner was born in 1897, to a genteel southern family. His father, Murry Cuthbert Falkner, was a railroad worker, owner of a cottonseed oil and ice plant, livery stable operator, hardware store employee, and secretary and business manager at University of Mississippi. His mother was Maud Butler Falkner. Falkner grew up and spent most of his life, off and on, in Oxford, Mississippi. He trained for the Royal Air Force in Canada, and later the British Royal Air Force during World War I, but the war was over before he saw action. After the war he briefly attended the University of Mississippi. He married Lida Estelle Oldham Franklin, June 20, 1929. The Faulkner works were greatly influenced by his family history. The area in which he lived had a great deal to do with his sense of the doleful position of Black and WhiteAmericans. This also influenced his sense of humor and is said to be the legacy of earlier writers like Mark Twain. Faulkner was best known for his novels, but he also wrote short stories, poetry and occasional screenplays.. Film versions have been made of several of his works: Sanctuary (1961), Intruder in the Dust (1949), The Sound and the Fury(1959), The Reivers (1969), and Pylon (1957; or Tarnished Angels). Others (Requiem for a Nun, 1951, and "Barn Burning") have been filmed for television. (Pierce, Constance, and Heller) Faulkner received the 1949 Nobel Prize for Literature for "his...

...insect repellents for domestic use. This is a very important investment for families as insects and various arthropod pests spread dangerous diseases, killing or sickening millions of people each year. In fact, the health of a family may sometimes depend even on the choice of insect repellent being used at home. Insects and other disease spreading pests can threaten the health and lives of families and individuals in a community, many lethal diseases such as Lyme disease, bubonic plague, dengue fever and malaria, for example, are spread by biting or stinging pests. The pests include all insects, example, the mosquito is responsible for spreading malaria, as well as ticks which spread Lyme disease. The citizens of first world countries typically tend to become infected through the bite or sting of insects and bugs while they are abroad. Indeed, travelers to exotic locales are often affected by nasty diseases transmitted by insects or bugs and bring such disease home with them. The greatest dangers lurk closer home and one need not travel across the world to face tiny pests. Many local insects and bugs in North America can cause serious diseases. Therefore, protecting the entire family through the prudent use of good quality insect and bug repellents is a necessity. Insects and bugs as vectors Each year, millions of people die from diseases transmitted by insects and other pests acting as vectors - an organism that acts as a host or carrier of some minute pathogenic organism that...

...Version 2 General Certificate of Education (A-level) June 2011 Geography GEOG1 (Specification 2030) Unit 1: Physical and Human Geography Post-Standardisation Mark Scheme Mark schemes are prepared by the Principal Examiner and considered, together with the relevant questions, by a panel of subject teachers. This mark scheme includes any amendments made at the standardisation events which all examiners participate in and is the scheme which was used by them in this examination. The standardisation process ensures that the mark scheme covers the candidates’ responses to questions and that every examiner understands and applies it in the same correct way. As preparation for standardisation each examiner analyses a number of candidates’ scripts: alternative answers not already covered by the mark scheme are discussed and legislated for. If, after the standardisation process, examiners encounter unusual answers which have not been raised they are required to refer these to the Principal Examiner. It must be stressed that a mark scheme is a working document, in many cases further developed and expanded on the basis of candidates’ reactions to a particular paper. Assumptions about future mark schemes on the basis of one year’s document should be avoided; whilst the guiding principles of assessment remain constant, details will change, depending on the content of a particular examination paper. Further copies of this Mark Scheme are available from:...

...geriatric medicine. As a physician you will be faced daily with the concepts of microbial disease and antimicrobial therapy. Microbiology is one of the few courses where much of the "minutia" is regularly used by the practicing physician. This book attempts to facilitate the learning of microbiology by presenting the information in a clear and entertaining manner brimming with memory aids. Our approach has been to: 4) Create a conceptual, organized approach to the organisms studied so the student relies less on memory and more on logical pathophysiology. The text has been updated to include current information on rapidly developing topics, such as HIV and AIDS (vaccine efforts and all the new anti-HIV medications), Ebola virus, Hantavirus, E. coli outbreaks, Mad Cow Disease, and brand-new antimicrobial antibiotics. The mnemonics and cartoons in this book do not intend disrespect for any particular patient population or racial or ethnic group but are solely presented as memory devices to assist in the learning of a complex and important medical subject. We welcome suggestions for future editions. 1) Write in a conversational style for rapid assimilation. 2) Include numerous figures serving as "visual memory tools" and summary charts at the end of each chapter. These can be used for "cram sessions" after the concepts have been studied in the text. 3) Concentrate more on clinical and infectious disease issues that are both interesting and vital to the actual practice of medicine.

...GLOBAL WARMING Introduction Global warming begins when sunlight reaches Earth. The clouds, atmospheric particles, reflective ground surfaces and ocean surface then reflected about 30 percent of it back into space, while the remaining is absorbed by oceans, lands and air. This in turn heats the planet’s surface and atmosphere, making life possible. As Earth warmed up, this solar energy is radiated by thermal radiation or infrared heat, traveling directly out to space, thus cooling the Earth. However, some of the outgoing radiation is re-absorbed by carbon dioxide, water vapor and other gases in the atmosphere and is radiated back to Earth’s surface; these gases are known as greenhouse gases due to their heat-trapping capacity. This re-absorption process is naturally good; the Earth’s average surface temperature would be very cold if not for the greenhouse gases. The problem begins when the concentration of greenhouse gases in the atmosphere were artificially raised by humankind at an ever-increasing rate since the past 250 years. As of 2004, over 8 billion tons of carbon dioxide was pumped out per year; natural carbon sinks such as forests and the ocean absorbed some of this, while the rest accumulated in the atmosphere. Millions of pounds of methane are produced in landfills and agricultural decomposition of biomass and animal manure. Nitrous oxide is released into the atmosphere by nitrogen-based fertilizers and other soil management practices. Once released, these greenhouse...

...Drug and Alcohol Review, (July 2005), 24, 369 – 385 Family interventions in the treatment of alcohol and drug problems ALEX G. COPELLO1, RICHARD D. B. VELLEMAN2 & LORNA J. TEMPLETON2 1 Birmingham and Solihull Substance Misuse Services and School of Psychology, University of Birmingham, UK and 2Mental Health Research and Development Unit, University of Bath, UK and Avon Witshire Mental Health Partnership NHS Trust Abstract Alcohol and drug problems affect not only those using these substances but also family members of the substance user. In this review evidence of the negative impacts substance misuse may have upon families are examined, following which family-focused interventions are reviewed. Several family-focused interventions have been developed. They can be broadly grouped into three types: (1) working with family members to promote the entry and engagement of substance misusers into treatment; (2) joint involvement of family members and substance misusing relatives in the treatment of the latter; and (3) interventions responding to the needs of the family members in their own right. The evidence base for each of the three types is reviewed. Despite methodological weaknesses in this area, a number of conclusions can be advanced that support wider use of family focused interventions in routine practice. Future research needs to focus on (1) pragmatic trials that are more representative of routine clinical settings; (2) cost-effectiveness analyses, in terms of...

Acquire skills for writing an effective argumentative essay rom August 1987 until January 2007, Alan Greenspan was chairman of the Federal Reserve Board (“the Fed”). Because any remark he made about U.S. monetary policy could cause markets all over the world to fluctuate wildly, he developed a complicated way of speaking that came to be known as “Fedspeak.” Here’s an example: It is a tricky problem to find the particular calibration in timing that would be appropriate to 2/9/2016 12:17 PM 3 of 56 stem the acceleration in risk premiums created by falling incomes without prematurely aborting the decline in the inflation-generated risk premiums.* Greenspan has admitted that such remarks were not really intended to be understood. Asked to give an example by commenting on the weather, Greenspan replied, I would generally expect that today in Washington, D.C., the probability of changes in the weather is highly uncertain. But we are monitoring the data in such a manner that we will be able to update people on changes that are important.* Page 70 2/9/2016 12:17 PM This tells us nothing about the weather...
