.... in people, they infect every form of life on earth. Some emerging viruses are very serious. Common examples are the viruses, B and C. The B pattern of illness was recognized at the end of the nineteenth century, yet the virus itself was not isolated until 1963. One hundred and seventy six million people are carrying the surface antigen of this one virus globally, and the infection causes a vast amount of illness and death, including most of the fatal cases of liver cell cancer.3 To prevent the wide spread of this disease, a rush for vaccination in the elementary schools fo .....

.... Later the term emerged through an English surgeon named James Braid. is a Greek word, which means sleep. Braid used it to describe the hypnotic state people would be in after . We now know that is not sleep, but an altered state of consciousness. Many people believe the is mythical and magical. Those supporting the mythical view of often cite studies which show that during the brain shows electrical changes and that the brain waves under differ from those during waking consciousness. There are many problems with the realism of . Many people feel that it's .....

.... noted for their destruction, some parts of the world, especially eastern Asia, rely on them for much of their precipitation. Although numerous tropical storms develop each year, only a few reach hurricane status, which by international agreement requires wind speeds in excess of 119 kilometers per hour and a rotary circulation. Hurricanes average 600 kilometers in diameter, and often extend 12,000 meters above the ocean surface. From the outer edge of the hurricane to the center the barometric pressure has on occasion dropped 60 millibars, from 1010 to 950 millibars. The l .....

.... caught stealing the materials needed to make a bomb. These terrorists have never been caught in the United States but numerous times in Europe.(www.pbs.org) As a matter of fact, the Russians say someone stole a bomb simulator, which will explode and make mushroom cloud but has no nuclear component.(Wilkie) People know that despite efforts to keep control on the old Soviet stockpile and waste, terrorists are getting the plutonium and uranium needed to make nuclear weapons to kill masses of people. This is kind of the history of the nuclear & atomic bomb: (all from Williams) .....

.... of the solar system that have been advanced during the last three centuries can be classified as either dualistic or monistic. A common feature of dualistic theories is that another star once passed close to the Sun, and tidal perturbations between the two stars drew out filaments of gas from which the planets condensed. Theories of this type encounter enormous difficulties in trying to account for modern information about the solar system, and they have generally been discarded. By contrast, monistic theories envisage a disk of gas and dust, called the primitive solar nebula, .....

.... used? Codeine is most useful in the relief of mild to moderate pain. It is also used as a cough remedy because it suppresses the part of the brain that triggers coughing, and as an anti-diarrheal drug, because it slows down muscle contractions in the intestinal wall. There are possible adverse effects. The most frequently observed adverse reactions include lightheadedness, dizziness, sedation, nausea, vomiting, and sweating. These effects seem to be more prominent in ambulatory patients and in those who are not suffering severe pain. Other adverse reactions include the followin .....

.... that the average temperature will rise 1.6 – 6.3°F by the year 2100, which could wreak havoc with climates around the world. Why are greenhouse gas concentrations increasing? Scientists generally believe that the combustion of fossil fuels and other human activities are the primary reason for the increased concentration of carbon dioxide. Energy burned to run cars and trucks, heat homes and businesses, and power factories is responsible for about 80% of society's carbon dioxide emissions, about 25% of U.S. methane emissions, and about 20% of global nitrous oxide em .....

.... ( Stoker 1). The question about the destruction of the ozone layer revolves around whether human-made CFCs (chloroflurocarbons) used in air- conditioners and refrigerators are breaking it down. This is the ozone thinning theory: "CFCs release chlorine into the stratosphere... leading to ozone destruction and exposing the planet to harmful ultraviolet rays." Critics who discount the thinning theory still say that chlorine comes from natural sources like volcanic eruptions and does no permanent damage (Brooks 422). NASA researches claim that they have evidence that shows CFCs .....
