.... workers. is one of the main computer professions in the world today. Computer programmer write, test, and maintain computer programs or software. Programmers are often categorized as technicians because of the work they do. Many programmers are involved in updating, repairing, modifying and expanding existing programs. They are often grouped into two types. These two types are Applications programmers and Systems programmers. Applications programmers usually are oriented towards business, engineering, or science. They write software to handle specific jobs within an organization such as a program used in a place of business .....

.... carry is also alarming. They are able to lie dormant for years before attacking their next victim. It is for this reason that the number of cases increases on a yearly basis. This is why individuals should take further precautions in preventing these diseases as well as preventing the spread of them on a global scale. Many people in today's society must take a more serious look at the implications that an infectious disease can have on one's life. What are STDS? Sexually transmitted diseases (STDS), also known as venereal diseases, is a broad term that refers to more than fifty diseases and syndromes, which may be transmitted through the .....

.... fuels, nuclear power, and hydroelectricity instead of coal has greatly reduced the occurrence of industrial smog. However, the burning of fossil fuels like gasoline can create another atmospheric pollution problem known as photochemical smog. Photochemical smog is a condition that develops when primary pollutants (oxides of nitrogen and volatile organic compounds created from fossil fuel combustion) interact under the influence of sunlight to produce a mixture of hundreds of different and hazardous chemicals known as secondary pollutants. Development of photochemical smog is typically associated with specific climatic conditions and ce .....

.... precise mechanisms of toxicity remain an enigma. The U.S. produces over a billion pounds of phosgene (CG) per year for industrial uses; however, we do not stockpile this agent for military use. Perfluoroisobutylene (PFIB) is a toxic pyrolysis product of tetrafluoroethylene polymers encountered in military materiel (e.g., Teflon7, found in the interior of many military vehicles). The oxides of nitrogen (NOxs) are components of blast weapons or may be toxic decomposition products. Smokes, e.g., HC, contain toxic compounds that cause the same effects as phosgene does. The remainder of this chapter will deal solely with phosgene because it i .....

.... Product Inhalation Program� which has been paid for by the U.S. Atomic Energy Commission. In this experiment 26 dogs died. One of the deaths occurred during an epileptic seizure; another from brain hemorrhage. Other dogs, before death, became feverish and anemic, lost their appetites, and had hemorrhages. The experimenters compared their results to those experiments conducted at the University of Utah and the Argonne National Laboratory in which beagles were injected with Strontium 90. They concluded that the dose needed to produce “early death� in fifty percent of the sample group differed from test to test because the dogs .....

.... (Md), and Nobelium (No). Plutonium was Seaborg’s first discovery. Its name came from Pluto, the planet after Neptune for which Neptunium was named. In 1940, at the University of California at Berkeley, he bombarded a sample of Uranium with deuterons, the nuclei in atoms of deuterium, transmuting it into plutonium. Shortly after, Seaborg was able to isolate plutonium 239, an isotope used in atomic bombs. Plutonium is a highly dangerous and poisonous element because it rapidly gives off radiation in the form of alpha particles. Alpha particles, which are identical to the nucleus of a helium atom, consist of two protons and two neutrons ti .....

.... B.C.) It is still true that approximately 70% of all deaths in the United States are from heart disease, strokes, and cancer. Other diseases, accidents, and violence account for the rest--but not age. These same diseases and Alzheimer's disease account for much of the disability attributed to aging. As these diseases are conquered, far more people will live to their full potential life span and remain active and healthy for life. A lot is known about the diseases that affect people and cause death. Much less is known about real aging because it involves fundamental cell processes that are quite complex. However, this mystery of li .....

.... born with no father. The father leaves the mother after they are through mating. When they are born, the cubs are blind and weigh from 25-32 ozs. At two weeks, once their eyes open, They can begin to explore outside of the den. At one month the cubs go go outside the den and follow their mother around. When six months comes and the cubs have learned how to do things the way their mother does, they begin to hunt with their mother. At one year the cubs can now hunt for their own food. Even though they can hunt for their own food they still stay with their mother for a few years before finding their own hunting territory. By three yea .....

.... are growing tremendously. The risks to the Earth¡¦s natural systems are becoming significantly concerning. The world¡¦s population, currently 5.2 billion has grown from about 3 billion in 1960, and around 2 billion in 1925. Today it increased by almost 90 million each year, and is likely to reach 10 billion by 2025(Corson 4). The reason we currently have an atmosphere crisis is because of human impact on the gases which make up our atmosphere. Our atmosphere, which is made up of four distinct layers blankets our planet and protects up in many way. One way it protects us if from the harmful rays the sun radiates on our planet. Each .....

.... was identified in 1989 and is known as transmembrane conductance regulator (CFTR) (Hopkin, 1998). is the most common genetic disorder in the white population (Hopkin, 1998). Almost every article or book about begins with a statement similar to the one above. People who have genetic disorders are born with them. The inherited genetic defect causes a chemical error in all the cells in their body (Silverstein, 1994; Wagner, Reynolds, Moran, Moss, Wine, Flotte, Gardner, 998; Shapiro, 1991; Drake, 1995). In children and adults with CF, a mistake in a single gene disables a type of protein that functions as an ion channel. This molecule re .....
