Tuberculosis TB is a disease that can cause a serious illness and can damage a person\'s organs. Every year more than 25,000 people in the U.S. are diagnosed with TB disease. That\'s only a fraction of the amount of people who carry the Mycobacterium tuberculosis. Mycobacterium tuberculosis is a rod-shaped bacterium. TB is spread through the air by carriers of the germ. People who breathe the same air can become infected with the TB germ. People who do work around or with people with the TB dise
U.S. Scourge Spreads South of The Border ____________________ A Written Final Project Presented to Professor Larry Herzog San Diego State University ____________________ MAS 355 The U.S. Mexico International Border ____________________ by Leo P. Dano Jr. December 02, 1996 In a recent newspaper article written in the San Diego Union Tribune called “U.S. Scourge Spreads South.” A very disturbing fact was opening drug doors just south of our own community, which is why I chose to do an in depth stu
Values MATT HEALTH OCT. 21, 1996 Three important values that I hold, are hard work, family, and friendship. These are values that I think will make life better and easier for a person. They make me feel secure and prepared for the future. Without these things I probably wouldn\'t care about anything at all. My values were all influenced by my parents. The only one that I had to figure out mostly by myself, was to work as hard as I could. Hard work is something that I had to do in order to prove
Vinegar Chris Nacey Writing 101 Final draft 2-19-1997 When I was a child, I spent a lot of time in the kitchen with my mother. She liked to cook and so did I. Because of this, I learned my way around the kitchen. I knew the place for everything, and I knew the uses of most everything. There was only one paradox, in my knowledge of the kitchen: vinegar. My mother had one bottle of vinegar for as long as I can remember. She never used it in cooking, or taught me how to for that matter. Our bottle
Vitamins In the early 20th century the discovery of vitamins began. Today there is a chance that there are some vitamins that are still undiscovered. The definition of vitamin is: one of several substances necessary for animal nutrition, and occurring in minute quantities in natural foods; numerous types have been distinguished, and designated by the letters of the alphabet. Each and every living animal needs vitamins to grow and be healthy. Since the human body can t produce vitamins naturally
Why Do Parents Abduct? According to the U.S. Department of Justice, over 354,000 children are kidnapped by a parent each year in divorce custody disputes. Some of the children are recovered or returned quickly while others may be on the run for years. Unfortunately many of these children are never found. Generally, people are concerned with the traumatic effects of these events on the child involved. However, both the searching parent and the abductor have many pending issues with which to deal.
Why Sex Education Should Be Taught In Schools Most America teenagers are sexually active and think nothing could ever happen to them. But, many of them are misinformed about the risks that are involved in sex. Teens also don\'t always know the best ways to protect themselves and their partners from becoming pregnant or getting STD\'s. Alan Harris said, the more educated someone is the more likely they are to make responsible and informed choice for their behaviors. Sex education given by teacher
Work Stress 1.0 Introduction Throughout the eighties and into the nineties, work stress have continued to rise dramatically in organizations across North America. The eighties saw employees stressing out from working in a rapidly growing economy. During the nineties, beginning from the recession of 1992 till present day, employees are stressed by their own job insecurities in the face of massive downsizing and restructuring of organizations in order to be competitive on the global stage. Work st
The Future Of The Internet In Today\'s world of computers, the internet has become part of ones regular vocabulary. The internet is everywhere, in the news, the newspaper, magazines, and entire books are written on it regularly. Its growth rate is incredible, increasing by about 10% every month (Dunkin 180). This rapid growth rate could either help the system or destroy it. The possibilities are endless on what can be done on the internet. People can tap into libraries, tap into weather satellit
Acid Rain THOUGHTS ON ACID RAIN Acid rain is a serious problem with disastrous effects. Each day this serious problem increases, many people believe that this issue is too small to deal with right now this issue should be met head on and solved before it is too late. In the following paragraphs I will be discussing the impact has on the wildlife and how our atmosphere is being destroyed by acid rain. CAUSES Acid rain is a cancer eating into the face of Eastern Canada and the North Eastern United
Acquired Immune Difficiency Syndrome AIDS is a life and death issue. To have the AIDS diseas is at present a sentence of slow but inevitable death. I\'ve already lost one friend to AIDS. I may soon lose others. My own sexual behavior and that of many of my friends has been profoundly altered by it. In my part of the country, one man in10 may already be carrying the AIDS virus. While the figures may currently be less in much of the rest of the country, this is changing rapidly. There currently is
Adaptation of the Bison This is a project about adaptation. If living things did not adapt to their environment they would become extinct. The bison is a very large animal. The bull grows to be ten feet long, six feet high, and weighs almost two thousand pounds. The bison has a large head, hump behinde the neck, long cured horns and a short tail. The long horns of the bison are used for protection againt predetors. Another adaptation of the bison is it\'s long curved horns, which are udes for de
Attention Deficit Disorder Chris Brown English 102: section 6 May 3, 1996 Approximately 3-5% of all American children have an Attention Deficit Disorder (ADD). ADD is a leading cause of school failure and under-achievement. ADD characteristics often arise in early childhood. As many as 50% of children with ADD are never diagnosed. Boys significantly outnumber girls, though girls are more likely to be undiagnosed with ADD. ADD is not an attention disorder, but a disorder of impulse control ( Sem
AIDS: Aquired Immune Deficiency Syndrome I am doing a report on AIDS, I don\'t know much about AIDS but I will tell you what I know. I know that it is transmitted by sexual contact,blood,needles,children during/before birth. I also know it affects the immune system directly, It is caused by the virus HIV which they have no cure for either AIDS or HIV at the current moment, but they are doing serious research on them. I call it the Generation X Disease because it mostly affects my sex- oriented
AIDS and HIV Introduction Being one of the most fatal viruses in the nation, AIDS (Acquired Immunodeficiency Syndrome) is now a serious public health concern in most major U.S. cities and in countries worldwide. Since 1986 there have been impressive advances in understanding of the AIDS virus, its mechanisms, and its routes of transmission. Even though researchers have put in countless hours, and millions of dollars it has not led to a drug that can cure infection with the virus or to a vaccine
AIDS and You Introduction: AIDS is a life and death issue. To have the AIDS disease is at present a sentence of slow but inevitable death. I\'ve already lost one friend to AIDS. I may soon lose others. My own sexual behavior and that of many of my friends has been profoundly altered by it. In my part of the country, one man in 10 may already be carrying the AIDS virus.

Air Pollution CFish Mr. Nollen Biology 2B 8 May, 1996 The Problem Contamination of the atmosphere by gaseous, liquid, or solid wastes or by-products that can endanger human health and the health and welfare of plants and animals, or can attack materials, reduce visibility, or produce undesirable odors. Among air pollutants emitted by natural sources, only the radioactive gas radon is recognized as a major health threat. A byproduct of the radioactive decay of uranium minerals in certain kinds of
Albinism The word albinism refers to a group of inherited conditions. People with albinism have little or no pigment in their eyes, skin, or hair. They have inherited genes that do not make the usual amounts of a pigment called melanin. One person in 17,000 has some type of albinism. Albinism affects people from all races. Most children with albinism are born to parents who have normal hair and eye color for their ethnic backgrounds. Albinism is found on the eleventh chromosome, section q, loc

A Massive Project for the Benefit of Mankind: A Look at the Human Genome Project Scientists are taking medical technology to new heights as they race to map all of the genes, nearly 100,000, in the 23 chromosomes of the human body. Along the way, they hope to understand the basis of, and maybe even develop methods of treating certain genetic diseases, such as Alzheimer’s and Muscular Dystrophy. They plan to do this by identifying the DNA sequence of an abnormal gene in which a disease originates
Alzheimer\'s Disease Alzheimer\'s Disease is a progressive and irreversible brain disease that destroys mental and physical functioning in human beings, and invariably leads to death. It is the fourth leading cause of adult death in the United States. Alzheimer\'s creates emotional and financial catastrophe for many American families every year, but fortunately, a large amount of progress is being made to combat Alzheimer\'s disease every year. To fully be able to comprehend and combat Alzheimer
America\'s Zoos: Entertainment to Conservation The children run ahead, squealing with delight. Their parents lag behind holding the children\'s brightly colored balloons and carrying the remnants of the half-eaten cotton candy. The family stops to let the children ride the minitrain and take pictures together under the tree. They walk hand- in-hand toward the exit, stopping first at the gift shop where they each splurge on a treat to remind them of the day\'s adventure. Although this may sound l
Amyotrophic Lateral Sclerosis (Lou Gherig\'s Disease) Amyotrophic Lateral Sclerosis is a deadly disease of the nervous system. Also known as Lou Gehrig’s disease, ALS at this time affects 25,000 people in the U.S. today. One in 50,000 people will be affected in any one year. The average age for diagnosis of ALS is between 30 and 70, although there have been cases of teenagers contracting it.The average life span after diagnosis are three to 10 years, although 20 percent of those affected will ou
Anabolic Steroids Anabolic steroids are synthetic coumpounds formulated to be like the male sex hormone testosterone. Many athletes use anabolic steroids male and female alike, such as body builders , weightlifters, baseball players, football players, swimmers, and runners. They do so because they mistakenly believe that they will gain strength and size. In a male testosterone is released by the leydig cells in the testes. The testosterone has two main functions androgenic and anabolic. Androgen
AIDS and Its Causes 1.INTRODUCTION In June 1981, the centers for The Disease Control of the United States reported that five young homosexual men in the Los Angels area had contracted Pneumocystis Carinii pneumonia( a kind of pneumonia that is particularly found in AIDS patient). 2 of the patients had died. This report signalled the begninning of an epidemic of a viral disease characterized by immunosuppression associated with opportunistic infection( an infection caused by a microrganism that d
Animal Cruelty The topic of animal cruelty is one of great importance to the wold today. Why we humans have the right reserved to treat animals as lesser individuals is beyond me. Animals are fulfilling their part in the ecosystems and communities of the earth, and to the best extent that they are able. For example, a spider is being the best possible spider that it can be, spinning webs and working diligently at what it knows best, not bothering any creatures of the earth besides the ones which
An Argument For Animal Research English 103 Paper #1 Animal Rights Medicine has come a very long way since the days when men used to puncture holes into the skull to release tension or evil spirits. In the last one hundred years, for the sake of humanity, numerous vaccinations have been developed, disease and disorders of all types have been prevented, surgical techniques have been advanced, drugs have been developed to cure ailments and the list continues endlessly. The progress that has been a
Animal Rights Ever since The Society for the Prevention of Cruelty to Animals in England in 1824 was formed there has been long running debates on the topic of animal rights. The first societies were formed to protect and maintain human treatment of work animals, such as cattle, horses and house hold pets. Towards the end of the 19th century more organizations were formed, this time to protest the use of animals in scientific experimentation. In today’s society groups such as People for the Ethi
Animals In The Research Lab The use of living animals is an important way to solve a medical problem. Researchers continually seek other models to understand the human organism, study disease processes, and test new therapies. In seeking quicker and not so expensive ways to look for biological information that can be applied to human disease, scientists sometimes study simpler things such as bacteria, fruit flies and a few other things. Researchers have spent many years learning how to sustain c
Solar Oven Why it will work: It will work because the cold air under the box will be separated by four (4) wood pegs. The black, non-glossy paint will attract heat, rather than reflect it. The glass, double panel, will allow heat to pass through, but not allow it to escape. The charcoal cubes and shavings will absorb the heat in the box and store the excess heat allowing the flow to continuously warm the oven. The tin foil will reflect heat and subsequently heat up the oven. The polyurethane mat
All About Ants (almost) Among the many hundreds of thousands of astonishing organisms with which we must share this earth, there is one seemingly ordinary group of specimens which fascinates many people beyond all others. There is nothing too extraordinary in the proportions or appearance of ants, but it is their history and culture that induces a second look. These insects are about as different from us mammals as two organisms can be, yet it appears that of all the known animals their way of l
Army Ants Anthony Palmieri November 20, 1996 Contemporary Science Topics A quote made by Lewis Thomas, Ants are so much like human beings as to be an embarrassment. They farm fungus, raise aphids as livestock, launch armies into war, use chemical sprays to alarm and confuse enemies, and exchange information ceaselessly. They do everything but watch television. I am going to focus this report on the part of the quote, ..launch armies into war.., which sets a metaphor of ants and our armies in
A Study Of Inheritable Traits in Fruit Flies INTRODUCTION The Drosophila melanogaster, more commonly known as the fruit fly, is a popular species used in genetic experiments. In fact, Thomas Hunt Morgan began using Drosophila in the early 1900’s to study genes and their relation to certain chromosomes(Biology 263). Scientists have located over 500 genes on the four chromosomes in the fly. There are many advantages in using Drosophila for these types of studies. Drosophila melanogaster can lay hu
Australopithecus By: Chris Stewart Date: December 15th 1996 Biology There are many types of the hominid called australopithecus, which means southern apes. These were small ape-like creatures(with a height between 107cm and 152cm) that showed evidence of walking upright. It is difficult to tell whether these begins are humans or apes. Many of their characteristics are split between humans and apes. The many species of australopithecus include A.(australopithecus) ramidus, A. anamenesis, A. a
Antibiotic Resistance in Bacteria For about 50 years, antibiotics have been the answer to many bacterial infections. Antibiotics are chemical substances that are secreted by living things. Doctors prescribed these medicines to cure many diseases. During World War II, it treated one of the biggest killers during wartime - infected wounds. It was the beginning of the antibiotic era. But just when antibiotics were being mass produced, bacteria started to evolve and became resistant to these medicin
The Effects of Antibiotics on Bacterial Growth Biology II 1996 Bacteria are the most common and ancient microorganisms on earth. Most bacteria are microscopic, measuring 1 micron in length. However, colonies of bacteria grown in a laboratory petri dish can be seen with the unaided eye. There are many divisions and classifications of bacteria that assist in identifying them. The first two types of bacteria are archaebacteria and eubacteria. Both groups have common ancestors dating to more than 3
Albert Einstein Einstein was born on March 14, 1879, in Ulm Germany. He lived there with his parents, Herman and Pauline. Einstein attended a Catholic School near his home. But, at age 10, Einstein was transferred to the Luitpold Gymnasium, where he learned Latin, Greek, History, and Geography. Einstein\'s father wanted him to attend a university but he could not because he did not have a diploma from the Gymnasium. But there was a solution to this problem over the Alps, in Zurich. There was T
Ancient Advances in Mathematics Ancient knowledge of the sciences was often wrong and wholly unsatisfactory by modern standards. However not all of the knowledge of the more learned peoples of the past was false. In fact without people like Euclid or Plato we may not have been as advanced in this age as we are. Mathematics is an adventure in ideas. Within the history of mathematics, one finds the ideas and lives of some of the most brilliant people in the history of mankind\'s\' populace upon Ea
Apollonius of Perga Apollonius was a great mathematician, known by his contempories as The Great Geometer, whose treatise Conics is one of the greatest scientific works from the ancient world. Most of his other treatise were lost, although their titles and a general indication of their contents were passed on by later writers, especially Pappus of Alexandria. As a youth Apollonius studied in Alexandria ( under the pupils of Euclid, according to Pappus ) and subsequently taught at the univers
Blaise Pascal Blaise Pascal was born at Clermont, Auvergne, France on June 19, 1628. He was the son of Étienne Pascal, his father, and Antoinette Bégone, his mother who died when Blaise was only four years old. After her death, his only family was his father and his two sisters, Gilberte, and Jacqueline, both of whom played key roles in Pascal\'s life. When Blaise was seven he moved from Clermont with his father and sisters to Paris. It was at this time that his father began to school his son. T
Blaise Pascal Blaise Pascal was born in Clermont France on June 19, 1623, and died in Paris on Aug. 19, 1662. His father, a local judge at Clermont, and also a man with a scientific reputation, moved the family to Paris in 1631, partly to presue his own scientific studies, partly to carry on the education of his only son, who had already displayed exceptional ability. Blaise was kept at home in order to ensure his not being overworked, and it was directed that his education should be at first co
Calculus One of the greatest contributions to modern mathematics, science, and engineering was the invention of calculus near the end of the 17th century, says The New Book of Popular Science. Without the invention of calculus, many technological accomplishments, such as the landing on the moon, would have been difficult. The word calculus originated from the Latin word meaning pebble. This is probably because people many years ago used pebbles to count and do arithmetic problems. The two pe
Carl Friedrich Gauss Carl Friedrich Gauss was a German mathematician and scientist who dominated the mathematical community during and after his lifetime. His outstanding work includes the discovery of the method of least squares, the discovery of non-Euclidean geometry, and important contributions to the theory of numbers. Born in Brunswick, Germany, on April 30, 1777, Johann Friedrich Carl Gauss showed early and unmistakable signs of being an extraordinary youth. As a child prodigy, he was sel
Karl Gauss: Biography Karl Gauss lived from 1777 to 1855. He was a German mathematician, physician, and astronomer. He was born in Braunschweig, Germany, on April 30th, 1777. His family was poor and uneducated. His father was a gardener and a merchant\'s assistant. At a young age, Gauss taught himself how to read and count, and it is said that he spotted a mistake in his father\'s calculations when he was only three. Throughout the rest of his early schooling, he stood out remarkably from the re
Eddie Vedder Is A Vampire Although at first he may seem to be just your average angst ridden lead man for a popular rock and roll band, Eddie Vedder, the vocalist and lyricist for Pearl Jam, may very well be a vampire. Although it is impossible to tell, everything points to his being an immortal. An in depth analysis of his lyrics shows that Pearl Jam\'s second album, “Versus”, has been used by Vedder as sounding boards for the complex emotions and change of perspective that come with one\'s tra
Bacteria Classification By Gram Staining THE AMERICAN UNIVERSITY IN CAIRO BIOLOGY DEPARTMENT SCIENCE 453 : BIOLOGY FOR ENGINEERS REPORT No.1 24/2/96 Objective: To test a sample of laboratory prepared bacteria and categorise it according to Christian’s gram positive and gram negative classes and also by viewing it under a high powered microscope and oil immersions; classify its shape and note any special characteristics. Introduction: Bacteria was categorised into two groups in 1884 by the Danish
Euclidean Geometry Geometry was thoroughly organized in about 300 BC, when the Greek mathematician Euclid gathered what was known at the time, added original work of his own, and arranged 465 propositions into 13 books, called \'Elements\'. The books covered not only plane and solid geometry but also much of what is now known as algebra, trigonometry, and advanced arithmetic. Through the ages, the propositions have been rearranged, and many of the proofs are different, but the basic idea present
Fibonacci Numbers The Fibonacci numbers were first discovered by a man named Leonardo Pisano. He was known by his nickname, Fibonacci. The Fibonacci sequence is a sequence in which each term is the sum of the 2 numbers preceding it. The first 10 Fibonacci numbers are: (1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89). These numbers are obviously recursive. Fibonacci was born around 1170 in Italy, and he died around 1240 in Italy. He played an important role in reviving ancient mathematics and made signific
The History of the Internet and the WWW 1. The History of the World Wide Web- The internet started out as an information resource for the government so that they could talk to each other. They called it The Industrucable Network because it was so many computers linked to gether that if one server went down, no-one would know. This report will mainly focus on the history of the World Wide Web (WWW) because it is the fastest growing resource on the internet. The internet consists of diferent pro
Fractal Geometry Fractal Geometry is not just a chapter of mathematics, but one that helps Everyman to see the same old world differently. - Benoit Mandelbrot The world of mathematics usually tends to be thought of as abstract. Complex and imaginary numbers, real numbers, logarithms, functions, some tangible and others imperceivable. But these abstract numbers, simply symbols that conjure an image, a quantity, in our mind, and complex equations, take on a new meaning with fractals - a concrete
