.... it is vital to be aware of how these deadly germs spread and what we can do to prevent them. Long before humans discovered antibiotics, they existed in nature. So naturally, after penicillin was introduced, some germs were already naturally resistant to the drug. As we used more and more of the antibiotics, we incidentally caused drug-resistant germs to progress. So, even if you’ve never misused antibiotics, you could still become infected by bacterium most drugs won’t kill. For each drug, there are germs genetically programmed to survive- some w/ outer walls tough for antibiotic to cross, others with ways to dump the drugs back out before they can wo ....

.... on doing this was to make something called the Philosophers Stone which would work by touching the stone to a metal and it would transform into the metal the alchemists wanted. Many alchemists would spend there whole lives searching for the substance that would start the transmutation that would make them rich, also many alchemists were hired by lords and noblemen who wanted to know the secret so they could become wealthier then they already were. Basically they saw easy money and would waste their lives and money to find out how to get it. There was another side to alchemy them just changing lead into gold, people not only wanted to be rich but they also wanted to liv ....

.... fabrics. It is fairly heavy and is made with a blue cotton warp and a white cotton filling (Groilers, 1996). The thermal underwear is duofold, with an outer layer made of 65% cotton, 25% wool, and 10% nylon, and an inner layer made of 100% cotton. It's the winter again and the weather is becoming colder. Each morning many people wonder what to wear to stay as warm as possible, but they aren't sure which material will keep them warmest. The experiment was chosen to see which clothing insulator retains the most heat. "Insulation is material that protects against heat, cold, electricity, or sound." (Science Encyclopedia, 1984). In this case the insulation will be protecti ....

.... delayed international action to reduce pollution for some time. However, with the coming of the 1970’s an awareness of acid rain spread, and with that awareness, possible solutions were proposed. These solutions involved making environmental changes on the international, industrial, and personal levels. Just how does acid rain form, and what consequences does it pose to our environment? There are numerous theories as to the cause of acid rain. However, the most prevalent is the theory that electric generating plants, heating plants, and other industrial plants have been emitting an excess amount of sulfur oxides, nitrogen oxides, and volatile organic chemicals (VO ....

.... alone. If we recycled only one-tenth of our newpaper, we would save 25 million trees a year. Second, making new paper from old paper uses up much less energy than making paper from trees. Finally, this process also reduces the air pollution of paper-making by 95 percent. Another earth saving habit is "precycling" waste. This means buying food and other products packaged only in materials that will decay naturally or that can be recycled. The idea is to prevent unrecyclable materials from even entering the home. For instance, 60 of the 190 pounds of plastic-especially styrofoam-each American uses a year are thrown out as soon as packages are opened. Be kind to your ....

.... will include what glucosamine sulfate is, how is works, and what it works on (osteoarthritis). Also included is an in-depth look at osteoarthritis, or degenerative joint disease (DJD), which is the most common type of arthritis, affecting over 16 million people in the United States today (1). Arthritis refers to inflammation or swelling of the joints. The most common form of arthritis is osteoarthritis, which is also known as degenerative joint disease because it is characterized by joint degeneration and loss of cartilage. Cartilage is the shock absorbing material between joints. The weight-bearing joints such as the knees, hips, and spine, as well as the hands, are the ....

.... expanding. They expand into an enormous escaping atmosphere called the coma. This becomes at least the size of our planet. With the comet going so fast, these materials are forced behind the comet, forming a long tail of dust and gas. Comets are cold bodies. We see them only because the gases they are composed of glow in the sunlight. All comets are regular family members of the solar system family. They are bound by gravity to a strict path around the solar system. Scientists believe that all comets were formed of material, originally in the outer part of the solar system, which did not become incorporated into planets. This material is from when the planets just ....

.... EU Draft Landfill Directive recognises three main types of landfill: Hazardous waste landfill Municipal waste landfill Inert waste landfill Similar categories are used in many other parts of the world. In practice, these categories are not clear-cut. The Draft Directive recognises variants, such as mono-disposal - where only a single waste type (which may or may not be hazardous) is deposited - and joint-disposal - where municipal and hazardous wastes may be co-deposited in order to gain benefit from municipal waste decomposition processes. The landfilling of hazardous wastes is a contentious issue and one on which there is not international consensus ....
