.... which send information to the main computer. Thiscomputer works with the data and displays them on the electronic spectacles. This is a technique which use three-dimentional views, therefore the scenery seems incredibly realistic. If you want to be a boxer, simply change thescenery on the main computer, and you are in the ring.Today, many kids have got video games. You could say these games are thepresent's answer to ludo and monopoly. In a way, it is a great advantage thatthe kids are being presented to computors at an early age, because they willdefinitely have to use them later, when they start to work. In the future the .....

.... steroid hormones it must convert cholesterol into estrogens and other related substances. In order for this process to take place, several steps are involved which are controlled by a certain enzyme. In knowing this, Lee wanted to find out if blocking the action of an enzyme would be reached with high doses of Provera. What Lee and Auchus found out was that Provera could inhibit certain enzymes, (3HSDII) which influence hormone production, that low doses of Provera could disrupt GnRH production and high doses were needed for a therapeutic effect. By knowing all this, it brings about new ideas for drug therapy when dealin .....

.... is nothing but a harsh reality that most people were unconcerned about until the disaster of the Exxon Valdez. The Valdez spill, tragically unnecessary though it was, has served as a laboratory for scientists, in which they can study the effects of oil pollution and experiment with new cleanup methods. It has also served as a costly lesson in the pitfalls of petroleum shipping and the shortcomings of emergency plans. It is time for us to learn from such an expensive lesson, and learn the horrid truths behind oil-spills; its cause, its effect and its solution. When most people hear the words oil-spill, they picture the wreck .....

.... benefits to humans, but limits have to be set. Our body contains one hundred trillion cells, inside most cells is a nucleus that contains a complete set of the body’s blueprints. Those blueprints are twisted into forty-six packets called chromosomes. Unravel a chromosome, and you get the long, thread-like molecule called DNA. Within the DNA are the blueprints, called genes, for which make proteins. The DNA molecule has a twisted, laddershaped structure (the famous double helix). The genetic code can be read in the rungs of the ladder. The code is spelled out by four chemicals: adenine (A), thymine (T), guanine (G), .....

.... reactions can occur. Creatine Monohydrate is a precursor to creatine phosphate. By supplementing with CM, CP levels in muscle apparently are maximized, and more muscular work can occur, since there are greater energy reserves to use. Approximately 95% of the body's creatine supply is found in the skeletal muscles. The remaining 5% are scattered throughout the rest of the body, with the highest concentrations in the heart, brain and testes. A skeletal muscle itself does not produce creatine, but utilizes the creatine originating in the liver and kidneys. The human body gets most of the creatine it needs from food or dietary .....

.... Many are afraid that the rich and famous might take advantage of the opportunity to generate copies of themselves. Nash points out that even though the possibility is there, the people who could grow full human clones "aren't going to be doing it." Nash recognizes that by individual cells for the purpose of eliminating life-threatening diseases many people could be benefited. Doctors could obtain healthy cells from a part of the human body and grow them in dishes to be used to fight against that particular disease. Nash sites that this could be helpful in such instances as leukemia and in burn patients. Leukemia pat .....

.... month, and *knew* there wasn't any other objects there." Thomas Bopp explains his story like this, "On the night of July 22, 1995 some friends and I headed out into the desert for a dark of the moon observing session. The site, which is west of Stanfield, AZ and a few mile south of Interstate 8 is about 90 miles southwest from my home. My friend Jim Stevens had brought his 17-1/2" Dobsonian. We started the evening observing some of the Messier objects such as the Veil and North American Nebulae in Cygnus, when Jim said " Let's look at some of the globulars in Sagittarius." We started our tour with M22 and M28, observing at 50 .....

.... chromatography works since the pigments in plants have different polarities, weights, and sizes. Although, it was hard to make a clear hypothesis as to how the pigments would travel due to my lack of knowledge of such pigments, I believed that the different pigments would indeed be divided. Furthermore that the lightest and most polar pigments would travel the most while the most non-polar and heaviest would be left in the bottom of the paper. The second experiment in our lab consisted on observing electron transport in chloroplasts. This was done using an electron acceptor called DCPIP which is a dye is blue in its oxidize .....

.... fishermen to catch the scallops not only do just that, but they also pick up everything else in their path. This has an impact on all marine life, particularly species such as sponges and barndoor skate which were almost forced to extinction because fishermen can't control what is being caught in the nets. The final concern is that reopening the waters that have been closed would set a bad example, by showing those involved that political pressure will prevail. On the other end of the spectrum, are those fishermen who rely on the profit made from their job. And since there are already about 200 more boats than experts e .....

.... truth is: teachers are not able to cope with them on an individual basis and give them more attention. An initial sign that some children demonstrate is a lack of concentration on virtually every task. Excessive disorganization beyond that of regular children along with being more than just the class nuisance can be characteristics of cocaine-exposed children. While most children are able to stay on task, these children will be easily deterred if given the opportunity. These children tend to exhibit a lack of exploration of the environment which results in less pretend play (Cates, 68). In a study done by Mayes, “when given a .....
