An Introduction To Vikings
The Vikings were explorers who lived in the region that is now Denmark, Norway, and Sweden. They often set sail for distant lands. Although their feats took place more than 1,000 years ago, the tales live on in legend. Stories tell of the sailors' voyages to new lands and of their violent raids. Two views of the Vikings have emerged from these accounts. One view is of the Vikings as brutal warriors who led vicious

Organic Chemistry
Distillation Andrea Pausma October 1, 2001 I. Introduction The process of distillation has been used by humans for years to create alcoholic beverages. Distillation is the process of boiling a pair of liquids with different boiling points and then condensing the vapors above the boiling liquid in an attempt to separate them. One might suspect that the mixed two liquids of different boiling points could be separated simply by raising the temperature to the lower

Very Brief Introduction To Cells
Cells were discovered in 1665 by Robert Hooke when he took a piece of cork and looked at it under a microscope. Cork is made up of dead cells but you are still able to see the cells which proved to be interesting to him. He described it as being made up like bricks in a wall and these bricks he then called cells. Due to the size of cells it is nearly impossible to

Chemistry
Chemistry is the study of the nature, properties, and composition of matter, and how these undergo changes. There different kinds of chemistry which are organic chemistry, Biochemistry, inorganic chemistry, physical chemistry, theoretical chemistry, analytical chemistry. Organic chemists study compounds of carbon. Atoms of this element can form stable chains and rings, giving rise to very large numbers of natural and synthetic compounds. Biochemists concern themselves with the chemistry of the living world. Inorganic chemists are

Chemistry And Carbohydrates
The Chemistry of Carbohydrates The chemistry of carbohydrates most closely resembles that of alcohol, aldehyde, and ketone functional groups. As a result, the modern definition of a carbohydrate is that the compounds are polyhydroxy aldehydes or ketones. The chemistry of carbohydrates is complicated by the fact that there is a functional group (alcohol) on almost every carbon. In addition, the carbohydrate may exist in either a straight chain or a ring structure. Ring structures incorporate

An Introduction To The Principles Of Morals And Legislation
"Nature has placed mankind under the governance of two sovereign masters, pain and pleasure. It is for them alone to point out what we ought to do, as well as to determine what we shall do." I think Jeremy Bentham was trying to infer that by our human nature, we may either choose to make a good decision or a band one. Pain would be referring to a bad decision, made without thinking over a

Cadmium is a chemical element in the periodic table that has the symbol "Cd" and atomic number forty-eight. It is a relatively rare, soft, bluish-white, toxic transition metal, cadmium occurs with zinc ores and is used largely in batteries. Cadmium is a common impurity in zinc, and it is most often isolated during the production of zinc. Zinc sulfide ores are roasted in the presence of oxygen converting the zinc sulfide to the oxide.

Nafta: A Brief Introduction
NAFTA: A Brief Introduction On January 1, 1994, history was made when the North American Free Trade Agreement (NAFTA) went into effect. NAFTA is in a sense a Trojan horse, attractive outwardly but filled with a host of unpleasant surprises. In simple terms, NAFTA is a treaty between Canada, Mexico, and the United States to make the transportation of goods, services, and capital across national boundaries more "hassle-free". Sounds perfect until you take a closer
