... rates. In 1997, an amazing 1.1 million debt plagued spenders filed for personal bankruptcy that was a 28.6% increase from '96. Economists predict another 1.6 million to file by the end of this fiscal year, (Shop 'til We Drop [STWD], 1997). These are two vivid examples of the amazing rate at which affluenza is growing. These numbers are occurring Causes & Cures despite the strong economy and perhaps because of it. With the economy in the U.S. going so well credit card companies are issuing more credit. Consumers are then using their new found credit to buy without even thinking of how they will pay for the products. They get the credit cards because of the ...

Mercurous chloride Hg2Cl2 which used to be used in medicine. fulminate Hg(ONC)2 used as a detonator in explosives and mercuric sulfide HgS used as a high-grade paint pigment. Organic compounds are important and dangerous. Methyl is a lethal pollutant found in rivers and lakes. is a virulent poison and is readily absorbed through the respiratory tract, the gastrointestinal tract, or through unbroken skin. It acts as a cumulative poison since there are few pathways available to the body for its excretion. Si ...

... hunter. This can make hunting a much harder sport to participate in, even for the people who are hunting for their livelihood. (Satchell 30) Over the years, hunting has reduced the animal population drastically. In the 1970's, the number of ducks making annual flights was approximately 91.5 million. In 1995, the number had been reduced to around 64 million. Within 20 years, in short, the duck population was reduced by almost one third, showing the drastic toll hunting is taking on our wildlife. If we assume that other species have been reduced in number at approximately the same rate in recent years, then what are the larger implications for our ecological balance? ...

New are being created with more strength and flexibility by combing two chemically different and producing a block copolymer. Combinations of block co and composites and intended for use in booster rockets and in materials of Earth-orbiting installations.

Although these still have the physical characteristics of liquid, they are structured more like solid ...

... average, develop each year in the warm sector of the North Atlantic. Although hurricanes are most 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 milliba ...

... and a growing number of participants. Theoretical studies of a-life, however, had been in progress long before the 1980s. Most notably, the Hungarian-born U.S. mathematician John VON NEUMANN, one of the pioneers of computer science, had begun to explore the nature of very basic a-life formats called cellular automata (see AUTOMATA, THEORY OF) in the 1950s. Cellular automata are imaginary mathematical "cells" --analogous to checkerboard squares--that can be made to simulate physical processes by subjecting them to certain simple rules called algorithms (see ALGORITHM). Before his death, von Neumann had developed a set of algorithms by which a cellular au ...

... to produce nearly ten times as much energy, while being only a fraction of the size. How the PEM Works: A is an electrochemical device that produces electricity silently, without combustion. Hydrogen fuel, which is one of the most abundant chemicals in the universe, and oxygen from the air are electrochemically combined in the to produce electricity. Heat and pure water vapour are the only by-products of the . The Ballard Fuel Cell is made up of two electrodes, the anode and the cathode, separated by a polymer membrane electrolyte. Both the anode and the cathode are coated in a thin layer of platinum catalyst. At the anode, hydrogen fuel is changed into fre ...

... reducing the need for natural gas and other nonrenewable resources). It is unfortunate that only a small part of our geothermal resources are being used today. Hot water, at temperatures between 300 and 700 degrees Fahrenheit, is brought from an underground reservoir to the surface and is converted to steam by using changes in pressure. The steam and liquid are separated, with the steam turning turbines (generating electricity) and the water is injected back into the reservoir to maintain the chamber's pressure. Sometimes the hot water is used directly for home, and sometimes greenhouse, heating. It is also used to speed up the growth of aquatic anima ...

... fibers have a few myoblasts, which remain as satellite cells. These myoblasts retain the capacity to join with one another or with damaged muscle fibers in order to regenerate these muscle fibers. John Centore2 Dr. Jain Anatomy & Physiology The many nuclei of skeletal muscle fiber are located underneath the sarcolemma, which is the fiber’s plasma membrane. Thousands of invaginations of the sarcolemma, which are called T Tubules, Tunnel from the surface to the center of the muscle fiber. These T Tubules are open to the outside of the fiber and are filled with extra-cellular fluid. Muscle action potentials propagate along the sarcolemma and through the T tu ...

... Between the years of 425BC-430BC Athens' population was dramatically reduced when about 300,00 of its inhabitants died from some sickness. Some people now believe that this great plague was really Ebola. The first recorded outbreak of the Zaire string of the Ebola virus was in Zaire, in 1976. The doctors didn't know how to treat it and that meant that they didn't know how to contain it either. As infected people met in public places the virus spread. In Western Sudan, the same year, the Sudan string of the Ebola virus emerged with similar results. Both casts together had about a total of 550 infections and around 340 deaths (about 60% death ...
