... are, nor does it care what nationality you are. The killer is carbon monoxide. Carbon monoxide, or CO as it is also called, is an odorless, colorless, and deadly gas given off when any fuel is incompletely burned by, for example, a furnace or water heater (Marable 97). Unlike a fire where you can immediately see smoke and flames, carbon monoxide poisoning gives no physical evidence of its presence. But, when taught to see and look for the warning signs of carbon monoxide, deaths in the home due to carbon monoxide poisoning can be prevented. Sometimes, in a home the hot water supply is low, or the furnace fails to keep the house warm. A natural reaction in a ...

... the balance. Tare the balance with a test tube inside a beaker. Add the amount to the tube. Vortex, gradually turning the speed up. Heat in a water bath. Cool the tube. 2. Wet the dialysis tubing with the beaker of distilled water. 3. Twist one end of the tubing. 4. Fold the twisted end over on itself. 5. Tie a tight knot. Leave the extra string. 6. Insert the transfer pipette (cut off top) about one third of the way into the tubing. 7. Tie a knot securely around the transfer pipette. Leave the extra string. 8. Add two transfer pipettes (two squirts) of the Gatorade solution to the tubing. 9. Add two transfer pipettes (two squirts) of the starch solution t ...

... Many people know of, or have at least heard of, UNIX. UNIX is both one of the oldest and one of the most powerful operating systems available today. "How can UNIX be old and yet powerful by today's standards”, you ask. The answer to this question lies in the history of UNIX; UNIX is a sort of subset of a much larger and more complex operating system called MULTICS. Both UNIX and MULTICS were developed decades ago for very large computers; only now, decades later are personal computers finally powerful enough to tackle these multitasking, multi-user systems with advanced features. Getting back to the crux of our first fact, LINUX looks like UNIX. LIN ...

... together into a long chain of bases to form the DNA molecule (much like pearls connect together to form a pearl necklace). The names of these four bases are adenine, cytosine, guanine, and thymine. Conventionally the bases are abbreviated as A, C, G, and T (respectively) for simplicity reasons. At the smallest level, DNA is organized into a double helix. The DNA helix is then repeatedly coiled to allow more of it to fit into a compact space. This helix replicates and passes on its information to the body's cells. In humans, all the DNA is packaged into 46 separate molecules called "chromosomes." The chromosomes each contain thousands of genes, with each gene spec ...

... has a long and complex life cycle which creates problems for immunologists. The vector for Malaria is the Anophels Mosquito in which the life cycle of Malaria both begins and ends. The parasitic protozoan enters the bloodstream via the bite of an infected female mosquito. During her feeding she transmits a small amount of anticoagulant and haploid sporozoites along with saliva. The sporozoites head directly for the hepatic cells of the liver where they multiply by asexual fission to produce merozoites. These merozoites can now travel one of two paths. They can go to infect more hepatic liver cells or they can attach to and penetrate erytherocytes. When inside t ...

... share the credit for first isolating elemental oxygen: Joseph PRIESTLEY (1733-1804), an English clergyman who was employed as a literary companion to Lord Shelburne at the time of his most significant experimental work, and Carl Wilhelm SCHEELE (1742-86), a Swedish pharmacist and chemist. It is generally believed that Scheele was the first to isolate oxygen, but that Priestley, who independently achieved the isolation of oxygen somewhat later, was the first to publicly announce his findings. The interpretation of the findings of Priestley and the resultant clarification of the nature of oxygen as an element was accomplished by the French scientist Antoine-Laure ...

... this procedure was done in order to let out the evil spirits which doctors thought possessed the mentally ill of this time. The literature of ancient Greece also contains evidence of the belief that evil spirits or demons controlled the mentally ill. Not only the Greeks believed in the evil spirit theory, writings from the early Babylonian, Egyptian, and Chinese civilizations have also shown evidence that was believed to be a possession by demons-using beatings, restraint, and starvation to try to drive out the evil spirits. These beliefs somewhat cooled down as time continued to move on, but once again popped up as America was starting to be formed. In 1692 ...

... the allergic or hypersensitive. Secondly, gold is extremely malleable and can be worked into amazingly fine detail. This is highly desirable for some types of fine filigree work and also means that a ring made out of 24 K gold can be easily opened and closed without special tools and without growing brittle and/or breaking as is the case with most harder alloys. The disadvantages are clear. The price is high and in its pure form it's so soft it wears quickly from the purely mechanic rubbing of your skin and of other jewellery. The common solution, however, is not without its flaws. "Cutting" the gold with cheaper metals can mean dramatic savings in material cos ...

... accurate statistics on lightning injuries and fatalities since a systematic compilation of information on lightning casualties does not exist. Many case histories show heart damage. Inflated lungs and brain damage have also been observed from lightning fatalities. Loss of consciousness, amnesia, paralysis and burns are reported by many who have survived. Deaths and injuries to livestock and other animals, thousands of forest and brush fires, as well as millions of dollars in damage to buildings, communications systems, power lines, and electrical systems are also the result of lightning. Finally, the threat of lightning causes many work stoppages and lost production ...

... problems, including rashes, respiratory problems and even cancers" (D4). In 1948, in the industrial town of Donora, Pennsylvania, which sits in a valley, had twenty deaths, and nearly 6,000 residents, or 40% of the population, suffered respiratory problems (Edelson 25, 26). New York experienced several killer smogs, which in a later analysis attributed, from the usually severe pollution, 58 deaths (Edelson 26). Not only in the United States are health problems caused by air pollution showing up, but they are also showing up in other parts of the world, like Europe. In 1930, in Belgium's Meuse River valley, a major industrial region, where the primary fuel was co ...
