.... 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 exchange of body fluids such as semen, vaginal fluid, and blood. An STD is a particular destructive process in an organism; which is likely to spread to others. These diseases can be spread in either the form of a germ or a virus and are able to spread in any number of ways. Though mos .....

.... plants generate only about eleven percent of the world's electricity. There are around 316 plants in the world that create 213,000 megawatts of electricity. (INFOPEDIA) Radioactive, or nuclear, waste is the by-product of nuclear fission. Fission occurs when atoms' nucleus' split and cause a nuclear reaction. (General Information) When a free neutron splits a nucleus, energy is released along with free neutrons, fission fragments that give off beta rays, and gamma rays. A free neutron from the nucleus that just split splits another nucleus. This process continues on and is called a chain reaction. (World Book vol. 14, 588) Th .....

.... This model assumes the perfect cosmological principle. This principle says that the universe is the same everywhere on the large scale, at all times. It maintains the same average density of matter forever. There are observational evidences found that can prove the Big Bang model is more reasonable than the Steady State model. First, the redshifts of distant galaxies. Redshift is a Doppler effect which states that if a galaxy is moving away, the spectral line of that galaxy observed will have a shift to the red end. The faster the galaxy moves, the more shift it has. If the galaxy is moving closer, the spectral line w .....

.... reaction, which is a release of energy. The electrostatic energy between the two holds them together. Ionic bonds are useful because in a liquid state it can conduct electricity. This is possible because it contains ions. That doesn't conduct electricity in the solid state because there is not enough room within the molecule. The substance produced by this bond is table salt. Other salts, such as CaCl (rock salt) are formed in the same way and although they have a different crystalline structure they do possess the same physical properties. Covalent bonds, as stated earlier, are when the atoms share electrons with each o .....

.... analyse information that the company has gathered for a single purpose, to make more intelligent business decisions. Whether to increase customer value, identify new markets or improve the management of the firm's assets, the data warehouse promises to deliver the information necessary to accomplish these tasks quickly and efficiently. This report entails various aspects of Data Warehousing, ranging from a clear and concise definition of its working system through to its operational environment. It discusses its implications and effects on internal and external interaction. I have presented my finding with the backing of so .....

.... of greenhouse gases increases. Since the beginning of the industrial revolution, great amounts of carbon dioxide have increased nearly 30%, methane concentrations have almost doubled, and nitrous oxide concentrations have risen about 15%. These increases have made the heat-trapping worse in the earth's atmosphere. Sulfate aerosols, a common air pollutant, cool the atmosphere by reflecting light back into space, but, sulfates do not live long in the atmosphere. Why are greenhouse gas concentrations increasing? Most scientists believe that the burning of fossil fuels and other human's doings is the main reason f .....

.... susceptibility to MS, it is not possible to inherit the disease. And even people who have all the necessary genes don't necessarily get MS. The disease, experts believe, must be triggered by environmental factors. So MS is not considered a hereditary disease.3 Until the definite cause of Ms is proved the treatment cannot be truly scientific. But there are treatments that are effective in dealing with symptoms. For instance, there are the common sense treatments that everyone, with or without an illness, should treat themselves with, which are: A healthy diet, exercise, sufficient amount of rest and to live your life as .....

.... I have already stated, there are more than 115 different types of arthritis. I will include the six most common forms in this report. Osteoarthritis Osteoarthritis is the most common form of arthritis in Canada. This type is also referred to as "degenerative joint disease", because it is a consequence of the wearing out of the cartilage that covers the end of bones, usually in the major weight bearing joints of the hips, knees, and spine. Joints in the fingers are occasionally involved as well. Osteoarthritis usually occurs later in life and, more often than not, affects only a few joints. It may also occur in a si .....

.... cardiac, ear, eye, pulmonary, brain surgeries, and other live saving surgery's. And most people faced with their death would rather live even if it meant killing animals. Next, animals help other animals as well. Veterinarians must learn the surgical techniques first so they can perfect their skills before they use them on other animals. Drugs for animals also use animal research to find cures for animal disease. Of course there are ways to avoid using animals in research. The way is to use investigators, cell, tissue, organ, and computer models to help lower animal usage. Though it is only useful in preliminary phases .....

.... bodies, some whole skeletons were found closer to the bottom, and some bones were scattered all over. It can be inferred from the patterning of the bison bones that they were butchered differently. Middle range theory also plays a part in the Olsen-Chubbuck site. From the visible remains of the bison, we can estimate from the skeletal remains of the bison that the total meat was 60,000 pounds and the total amount of people capable of butchering the bison would be 150, thereby relating the artifacts to past human behavior. Archaeologists also study patterning in time and space; time, being vertical and space being horizontal. .....
