.... mostly in stars, where it goes through nuclear fusion with hydrogen. Most Helium comes from natural gas taps in North America. It is used in balloons and divers use it with oxygen to breath easier and to not get sick or dizzy. Neon is an element that is lighter than air. The element is found most common in the atmosphere of the earth. It is also found in the earth¹ s crust. It was discovered in 1898 by Sir Walter Ramsey and Morris W. Travers. Its uses include electric signs,lamps,and lasers. Argon is the most abundant and most used noble on earth. It was discovered by Lord Rayleigh and by Sir Walter Ramsey in 1894. Argon makes up about 1.2 % of the earths atmosph ....

.... a network that could reroute itself around damage caused by the impact of an Intercontinental Ballistic Missile by using "redundancy of connectivity". This meant that in the event of a break in the network the server would re-route the information in an alternate path through a new technique called "packet switching". Packet Switching is a means of breaking up the message being sent into small packets which carry enough information to seek out its destination and sending them out separately towards the destination server. The message after being broken up would take separate routes to the destination and then be re-assembled by the computer at the server where the messag ....

.... zero. There are also two main sciences used in cryogenics, and they are Superconductivity and Superfluidity. Cryogenics first came about in 1877, when a Swiss Physicist named Rasul Pictet and a French Engineer named Louis P. Cailletet liquefied oxygen for the first time. Cailletet created liquid oxygen in his lab using a process known as adiabatic expansion, which is a "thermodynamic process in which the temperature of a gas is expanded without adding or extracting heat from the gas or the surrounding system"(Vance 26). At the same time Pictet used the "Joule-Thompson Effect," a thermodynamic process that states that the "temperature of a fluid is reduced in a proce ....

.... for animals to exercise and play. A water supply is not always readily available in all locations, leaving many animals with out water. Furthermore, with out water, cleaning becomes a low priority. This is very hard on animals especially elephants who bathe frequently in their natural environment. But, the circus environment is very different from an animal’s natural habitats. Summer can be hard on animals such as bears, while lions, can suffer more in winter months. Veterinarians qualified to treat exotic animals, are not always present or available. As a result animals suffer and die due to the lack of proper medical attention. Physical confinement is very harm ....

.... excitement and competitive fervor something great and disturbing was being bypassed. Science, in my view had done something great without looking into the possibilities of where this would lead. I believe Djerassi, similar to most scientists of his day, was so entranced by the excitement of synthesizing his product and achieving his goal that he did not stop to think of the ramifications of his accomplishment. The ethical dilemma was not explored before hand, and this to me is the great tragedy of most scientific discovery, since I firmly believe each scientist is responsible for that which he creates. Djerassi does confront a few questions of ethics and morality afte ....

.... of fiber optics are numerous. Fortunately for the high-tech society of today, some scientists and technicians researched the avenues of fiber optics. Fiber optics can be seen in telephone systems, in the military, in cars, in medicine, and in many other fields of study. For all industries and professions, "Fiber optics allow huge amounts of voice, data and video imagery to be transmitted instantaneously, allowing for photographic-quality images, interactive video conferencing and other business multimedia uses" (Inman News Features 1). It's becoming possible to transmit audio, video and data signals over great distances using these fibers of pure glass or plastic. Today, f ....

.... and lightweight fiberglass to make a near perfect match with most people. The most common prosthesis is the replacement in a below the knee amputation. The American Society of (ASB) held a meeting at Clemson University of 1997 in order to develop a sports prosthesis that would stand up to every day flexing of the knee for performance in sports. In order to develop this prosthesis they had to go through two main phases, the analysis of a jogger wearing a standard walking prosthesis and computer simulation of the flexing of the knee on this walking prosthesis. They had to measure rotation, weight bearing, moments, and the stress of the joints acting on this limb. After ....

.... of pressure, cutting the seal in half. The Great White shark claims another victim.1" Any one who’s seen the famous movie series "Jaws" may look at the Great White Shark in a similar manner. Perhaps it’s the way that Hollywood uses a mix of fact and fiction in the series. This may have frightened many people into hating the Great White for it’s ferocity. It might have also been the size of the shark in the movie that’s kept thousands of people off the beaches and out of the water. Better yet, it could have been the overall storyline: A Great White shark with an eating disorder and a taste for human flesh. Perhaps that’s what is keeping vacationers ....
