.... The Internet transcends geographical locations, and is the first example of a true global village. Unfortunately for regular users of the Internet, much like the real world, criminals exist on the Internet as well. "Hackers," the computer wizards who use their knowledge for evil, are rampant on the Internet. Sometimes they do seemingly harmless acts, such as just going into a computer system and observing, but at other times, they steal, destroy or alter data. On some occasions, these cyber-felons perform even more malicious acts, such as infecting systems with "viruses," computer programs that "infect" the systems by latching onto other .....

.... he convinced his father to let him leave the school without a degree. Galileo was a math tutor for the next four years in Florence. He spent a lot of the four years studying the scientific thoughts and philosophies of Aristotle. He also invented an instrument that could find the gravity of objects. This instrument, called a hydrostatic balance, was used by weighing the objects in water. Galileo returned to Pisa in 1589 and became a professor in math. He taught courses in astronomy at the University of Pisa, based on Ptolemy's theory that the sun and all of the planets move around the earth. Teaching these courses, he became more un .....

.... cycle, it was taxonomically classified in a separate order. It can thus be found with the other well-known intracellular parasites, rickettsiae, in diagnostic manuals. Until recently, however, there were no reliable and easy tests for chlamydia. Chlamydia prevention and patient care were impeded by the lack of suitable laboratory tests for screening and diagnosis. Such tests are now available. Through education, screening, partner referral, and proper patient care public health workers and health-care practitioners can combine efforts to decrease the morbidity and costs resulting from this infection. Chlamydia is the number one .....

.... glucose, mannose, and galactose; fructose is a ketohexose. Several derivatives of are important. Ascorbic acid (vitamin C) is derived from glucose. Important sugar alcohols (alditols), formed by the reduction of (i.e., addition of hydrogen to) a monosaccharide, include sorbitol (glucitol) from glucose and mannitol from mannose; both are used as sweetening agents. Glycosides derived from are widespread in nature, especially in plants. Amino sugars (i.e., sugars in which one or two hydroxyl groups are replaced with an amino group, -NH2) occur as components of glycolipids and in the chitin of arthropods. carbohydrateClasses of carbohydrate .....

.... way come to be is the mineral matter concentrates around the nucleus of a host rock. The nucleus is often organic such as a tooth or leaf or shell or fossil. As the mineral matter concentrates around the nucleus it forms harder zones known as nodules. are very odd in the sense that they very in size, shape, color and hardness. Often are mistaken for bones, fossils, meteorites and other odd objects. They can be so small that it requires a magnifying glass to be visible or as large as 10 feet in diameter and weigh hundreds of pounds. can also have somewhat of regular shapes such as boxes, blocks, flat disks, pipes, cannon balls and h .....

.... is the fact that they lack the basic elements for reproduction, deoxyribonucleic acid and ribonucleic acid DNA and RNA respectively. This is what has given science a great deal of doubt as this would give the dogma of the beginning of live a radical turn. Prions have been in research for many years with experiments like the one done by Stanley B. Pruiser and his team of scientists at the School of Medicine of the University of California at San Francisco in which a study was carried out on mice to see if he was able to purify the scrapie agent ,another prion disease, in mice. But mice as humans took very long to develope the disease, for .....

.... and medical treatments, as well as comprehensive educational treatment provide the best care and placement of both adults and children afflicted with . Adult psychotic disturbances were noted in the early twentieth-century classifications of mental disorders (Nelson, Israel, 1997). The descriptions and classifications of these disturbances, however, were confusing and controversial. Kraeplin set the basis for modern classification. He used the terms dementia, a belief that progressive deterioration occurred, and praecox, meaning the disorders began early. Later the term schizophrenia was applied by Bleuer. He argued that deteriorati .....

.... 300 per day, 10 per hour, another dead species every 6 minutes. We're trashing the planet, washing away the topsoil, paving over our farmlands, systematically deforesting our wildernesses, decimating the biota, and ultimately killing ourselves. The world is getting progressively poorer, and it's all because of populating, or more precisely, over-population. There's a finite store of resources on our pale blue dot, spaceship Earth, our small and fragile tiny planet, and we're fast apporaching it's ultimate carrying capacity. The limits to growth are finally upon us, and we're living on borrowed time. The laws of population growth are ine .....

.... of earth by reflecting much of the suns harmful ultra violet (UV) rays. Without this layer above us, many living things including humans could not survive. The ozone layer is currently depleting and the reason for this is believed to be caused by a few things. Deforestation, fertilizer use and fuel combustion are minor contributors to this problem while chemicals such as chloroflourocarbons (CFCs), halons, carbon tetrachloride, methyl chloroform, methyl bromide and hydrochloroflourocarbons (HCFCs) are the major contributors to the deterioration of the ozone layer. These chemicals have industrial halocarbons that break up into chlorine a .....

.... between these diseases, and the fact that they can occur in milder or more sever forms leading to an overlap of the most obvious symptoms. (7) Chickenpox mostly occurs in children classifying it as a childhood disease although it can occur in adults who are not yet immune to it. This could lead to the belief of chickenpox being one of the oldest diseases. Since the chickenpox infection has two phases, one most common during childhood then a latent form that can become active again later in the persons life, doctors believe that this reactivation would start the cycle all over again. If everyone in the first cycle got the germ th .....
