.... In today’s growing entertainment market, the difficulty in accessing video and DVD movies can play a large part in the decision of which component is right for the consumer.METHODSThe beginning of any research project is in the decision of a topic to research. I chose to research the differences between the VCR and DVD home entertainment systems because the intricacies of the systems and the ways in which they work greatly interest me. I began my work using ordinary encyclopedias, found in the Rosewood High School branch of the Wayne County Public Library. Due to the technical nature of .....

.... to radio is the possibility of listener interactivity. Currently, any interactivity is limited by the inability of the individual talk to the other end of a radio transmission chain. When one switches stations on our radio, there is no interaction, we are simply selecting from a series of predefined options, just like changing channels on television. If you switch from one station to another, none of the stations know about it, and can do nothing to make their programming more interesting than their competition. The Internet has no such limitations, from the ground up; it was designed as a .....

.... 'vitrification'. Vitrification is a semi-continuous process that enables the following operations to be carried out with the same equipment: evaporation of the waste solution mixed with the additives necesary for the production of borosilicate glass, calcination and elaboration of the glass. These operations are carried out in a metallic pot that is heated in an induction urnace. The vitrification of one load of wastes comprises of the following stages. The first step is 'Feeding'. In this step the vitrification receives a constant flow of mixture of wastes and of additives until it is 80% .....

.... forests, the world could become hotter than it has been in the past million years. Average global temperatures have risen 1 degree Fahrenheit over the last century. If carbon dioxide and other greenhouse gases continue to spill into the atmosphere, global temperatures could rise five to 10 degrees by the middle of the next century. The warning will be the greatest at the higher latitudes of the Northern Hemisphere, with the largest temperature rises occurring in winter. Most areas will experience summertime highs well above 100 degrees Fahrenheit. New temperature records will be set each ye .....

.... making laws that you are not allowed to hunt or kill any animal that is in danger of extinction. Government Involvement Only since the 19th century has there been worldwide concern about the case of species in their natural environments. Finally in 1916 they made a law called Migratory Bird Treaty. They had this law in United States, Great Britain, Canada, and later in Mexico. This law was made so that people can not kill animals that are endangered. This law did not work that well because the animals that were endangered were not put in zoo’s. People still killed theses animals .....

.... Act to provide incentives to natural gas producers for stripping natural gas of its helium, for purchase of the separated helium by the government, and for its long-term storage. With over 960 million cubic meters (34.6 billion cubic feet) of helium in government storage and a large private helium recovery industry, questions arise as to the need for either the federal helium extraction program or the federally maintained helium stockpile. In a move which would take the federal government out of the helium business, Congress passed the Helium Privatization Act (H.R. 873) as part of the Seven .....

.... moon and the stars, which You have ordained; what is man that you are mindful of him? And the son of man, that You visit him?" Creationism is the product of a literal interpretation of the Biblical story of Genesis. It holds that God created the world in a single act approximately 6,000 years ago--and that human beings, animals, and other forms of life exist today much as they did then. To many creationists, the theory of evolution is heresy. They argue that fossil records and other scientific evidence of evolution are either false or were themselves created by God. "In the beginning, .....

.... care unit. In some of the smaller hospitals they aren’t equipped with the technology that is needed to keep the baby alive and the baby has to be transported to a bigger hospital, usually to a hospital in a metropolitan city in order to get the proper care. After the baby has been assessed for problems then it is watched closely for the next 48 hours. This is the most critical time for a baby . During this time the doctors can determine if the baby is going to have a long road ahead of them or if the baby is healthy and will pull through the whole thing with flying colors. Sometimes, .....

.... by modern physicists, the use of the scientific method becomes the qi researchers¡¦ best tool. In addition, while qi and the atom were both conceived by ancient philosophers, the notion of the atom was better developed by scientists than the idea of qi. Therefore, by looking back at the historical progression towards a belief in atoms and the deduction of their structure, we know how scientists built up the atomic theory. Consequently, the concept of historical progression will help us understand why the notion of qi is hard to define by physicists, and how it could be develope .....

.... 1992). A radioisotope is a radioactive isotope (The America Heritage Dictionary of the English Language, Third Edition, 1992). A radioisotope is a naturally or artificially created isotope having an unstable nucleus that decays, letting off alpha, beta, gamma rays until stability is reached (The America Heritage Dictionary of the English Language, Third Edition, 1992). Radon's melting point is -71°C. The boiling point is -61.8°C. Radon is the densest gas known (Concise Columbia Encyclopedia, 1995). Radon is a heavy, colorless, odorless, tasteless, non-flammable gas (therefore it c .....
