... and sulfur from the ore cassiterite. When you smelter the tin you must heat it with carbon to remove the zinc, copper, bismuth, and iron from the tin. Tin had been used for many things but tins use is dropping rapidly although tin is still used a lot for plating. Plating such things as electical contacts. Tin is also used as a protective coating. This protective coating can be as small as 15/1,000,000 of an inch. This protective coating protects against rust on steel and other metals. A coating of tin also gives a great look to plain old steel. Tin cans for food prevents weak acids from damaging the inside of the can. Not many cans are made of tin sinc ...

... bacteria. They elongate for 12 to 24 hours before dividing into two cells. B. burgdorferi is approximately 20 to um long and 0.2 to 0.25 um wide, with 7 to 11 flagella. More than 30 proteins are contained within B. burgdorferi1. This bacteria uses white-footed mice, mosquitoes, and deer as their hosts. This disease does not discriminate between sex and age; male and female, as well as old and young are affected. It is widely distributed around the world in the temperate zones3. A person is infected when a black-legged tick imbeds itself into them while out in the open in wodded and forested areas. This usually occurs between the months of May a ...

... last a very long time. The television field uses around four kinds of microphones as basic equipment; the hand-held omnidirectional, the tiny lavalier mic, which is used by clipping on clothing, a wireless microphone called the transmitter mic, and the shotgun mic. The Omnidirectional Microphone comes in many different shapes and sizes. They are used when the background sound is normally low. They usually work by pointing the mic directly at the source of the sound. This mic is not good for loud background sound because the mic might not be able to distinguish between the different sounds. The Lavalier Microphones are small mics that have a more unidirectio ...

... quite itchy and becomes dry, crusted, and falls off in a week. More bumps will come about every three days. Scars will be present if they get infected, badly scratched or removed. A physician is not usually not needed to make a diagnosis but after the symptoms appear it is still best to make sure it is the chicken pox and not something much worse. The physician can easily make a diagnosis by checking the basic symptoms. Chicken pox is controlled by keeping the infected person and anything the infected person has come in contact with away from any people who have never become infected. There is not really a treatment, just medicine so that the rash does n ...

... when F.C. Steward cloned carrot plants from mature single cells placed in a nutrient culture containing hormones. The first cloning of animal cells took place in 1964. John B. Gurdon took the nuclei from tadpoles and injected them into unfertilized eggs. The nuclei containing the original parents’ genetic information had been destroyed with ultraviolet light. When the eggs were incubated, Gurdon discovered that only 1% to 2% of the eggs had developed into fertile adult toads. The first successful cloning of mammal was achieved nearly twenty years later. Scientists from Switzerland and the U.S. successfully cloned mice using a method similar to Gurdon’s, but require ...

... causes include the death of a loved one, an abortion or miscarriage, a move to a new home or job, the end of an important relationship, financial problems, a chronic illness, or any other traumatic event. For many people, these incidents produce a mild to moderate case of the blues. They feel "down" for a while, but they are able to continue functioning and performing everyday tasks. Although these people may experience the chemical imbalance that is the hallmark of depression, the brain abnormality typically corrects itself within a few weeks. However, in some critical cases, the chemical alteration lasts for a much longer time, this is when mild to modera ...

... causing pulls and tears. Liver and kidney damage are caused by Creatine increasing the amount of ATP (adenosine tryphosphate) that is used for energy, made by the kidneys, which can cause the kidneys to stop producing ATP because of an overload of ATP being made from the Creatine. This can result in kidney or liver failure. Constriction of the blood vessels occurs when you use Creatine and work out for extended amounts of time. This can cause major constriction of the vessels around the heart causing abnormal heart rates and heart attacks. Pancretitis is another side effect where the pancreas stops working and fails. Creatine is said to be directly related to pancre ...

... did not release Carbon Dioxide because they were not a food source for yeast. The results suggest that sugars are very good energy sources for a cell where amino acid, Glycine, is not. INTRODUCTION Fermentation is an anaerobic process in which fuel molecules are broken down to create pyruvate and ATP molecules (Alberts, 1998). Both pyruvate and ATP are major energy sources used by the cell to do a variety of things. For example, ATP is used in cell division to divide the chromosomes (Alberts, 1998). By taking a Carbon Dioxide, rich substance and mixing it with a yeast, solution fermentation will occur, and then it could be determined if ...

... was mentioned the first thing that came to people's minds were the bombings of Hiroshima or Nagasaki. No one ever considered the fact that plutonium could be used for more constructive purposes such as: sources of energy or to keep a person's heart beating. We did begin to produce more plutonium but the majority of the substance was used towards our nuclear weapons programs. Along with reactors, sometimes comes a meltdown which can cause harmful effects if it isn't controlled quickly enough. After such instances as the Hanford, Washington reactor meltdown and the accident in the U.S.S.R. at the Chernobyl site, no one wanted to hear about the use of plutoni ...
