.... the Middle Ages that its poisonous characteristics were described. It was identified by Albert Magnus about 1250, and he described the way to manufacture it. Since then the method has scarcely changed: the mineral arsenopyrite is heated and decomposes with the liberation of gas. The gas can be condensed on a cold surface. Metallic was first produced in the 17th century by heating with potash and soap. General Properties is very similar to antimony and bismuth. It exists in bright, metallic forms that are stable in air. It is found free in nature or in co .....

.... seeking to utilise the massive amounts of data they are accumulating. Managers from all business disciplines want enterprise wide information access, as well as the ability to manipulate and analyse information that the company has gathered for a single purpose, to make more intelligent business decisions. Whether to increase customer value, identify new markets or improve the management of the firm's assets, the data warehouse promises to deliver the information necessary to accomplish these tasks quickly and efficiently. This report entails var .....

.... problems, including low self-esteem. This disorder also affects family members through anger and frustration because of the condition. One important reminder to parents with children who suffer from this condition is that bed-wetting should not be thought of as a behavioral problem. There is no medical proof to show that children wet the bed to spite their parents. Also, most children will outgrow bed-wetting eventually. As parents, the best way to help your child is to be understanding and remember that punishing or making fun of .....

.... The hurricane season is the six month time period from June-November. The peak month of hurricanes is September. Hurricanes form over the ocean. Easterly waves, what hurricanes develop from, are long, narrow regions of low pressure which occur in ocean winds called trade winds. At first, these easterly waves can grow into something called, a tropical depression. A tropical depression occurs when winds are up to 31 mph. Then tropical depressions can be upgraded into a tropical storm if the winds reach speeds of 74 mph or less. Then finally a the storm can be .....

.... 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 ferm .....

.... generally have ethical objections regarding treatment of animals during experimentation, but the use of animals in research for the benefit of all people is and always will be justifiable. Over 99 percent of all animal experiments are on rats and mice developed expressly for laboratory use. "Less than 1 percent of experiments involve cats, dogs, farm animals, nonhuman primates, frogs, fish, and birds." ( ¯Encyclopedia of Medicine, AMA®, "Animal Experimentation", Page 110.) Animal rights advocates try to sway public opinion by showing grotesque pictures of .....

.... genes into the DNA of living organisms. Genetic engineers believe they can improve the foods we eat by doing this. For example, tomatoes are sensitive to frost. This shortens their growing season. Fish, on the other hand, survive in very cold water. Scientists identified a particular gene which enables a flounder to resist cold and used the technology of genetic engineering to insert this 'anti-freeze' gene into a tomato. This makes it possible to extend the growing season of the tomato. The marketing of genetic engineering inspires visions of perfect health, lon .....

.... for this defect. There are two types of haemophilia, haemophilia A and B. Haemophilia A is a hereditary disorder in which bleeding is due to deficiency of the coagulation factor VIII (VIII:C)3. In most of the cases, this coagulant protein is reduced but in a rare amount of cases, this protein is present by immunoassay but defective.4 Haemophilia A is the most common severe bleeding disorder and approximately 1 in 10,000 males is effected. The most common types of bleeding are into the joints and muscles. Haemophilia is severe if the factor VIII:C levels are less .....
