... belongs to them all. Security on the Internet is a very important issue in the world today. Billions of people have an on-ramp to the Information Superhighway, and more are finding one every day. The Internet transcends geographical locations, and is the first example of a true global village. Unfortunately for regular users of the Internet, much like the real world, criminals exist on the Internet as well. "Hackers," the computer wizards who use their knowledge for evil, are rampant on the Internet. Sometimes they do seemingly harmless acts, such as just going into a computer system and observing, but at oth ...

... cholesterol -- the "good" cholesterol -- in the blood. Doctors participating in the Physicians' Health Study reported recently in the Journal of the American College of Cardiology that one drink a day can help lower the risk of heart disease. But when consumption surpasses two drinks a day, risks increase for some kinds of cancer. Doctors at UT Southwestern Medical Center at Dallas say before you start drinking for your health, talk to your doctor. For some people, the risks of alcohol outweigh the benefits. And remember that while one drink a day can be helpful, more can be harmful. Could a drink a day keep the d ...

... census was 1500. Therefore saying that the Bali tiger, theCaspian tiger, the Javan tiger, the Manchurian tiger, and the Southwest Chinese tiger are now extinct doesn't give you aportrait of the process of extinction. The Javan tiger became extinct in the 1970's in a set aside special national park under full protection. Politicans and bureaucrats seem to be obsessed with numbers and not trends. Let me illustrate this with tigers. There are frequently requests as to the exact number of tigers, or a tiger subspecies left in the world. That tells you that there are people that care. But there are so little tigers ...

... the benefits. Animal experimentation was not common until the early nineteenth century and emerged as an important method of science. The first recorded action of vivisection was the study of body humors by Erasistratus in Alexandria during the third century (1:3). Later, in A.D. 129-200, the physician, Galen, used five pigs to investigate the effects of several nerves (1:4). He is considered to be the founder of experimental physiology. During the Renaissance Era, Andreas Vesalius conducted experiments on monkeys, swine, and goats (1:3). By the late eighteenth century, the methods of scientific discovery were c ...

... Apollo Spacecraft was developed from the work of two other programs, the Mercury and Gemini Programs. The actual spacecraft was made of the combined Command Module and the Service Module also called the CSM. It was 34ft. long and 10ft. in diameter at the end. It had a major advantage with its internal guidence system, that was developed by The Massachusetts Institute of Technology. The CSM was made of two parts. The crew stayed in the Command Module, which had some couches and was pressurized with oxygen. Behind the CM was the SM or Service Module which had the main engine, which had 21,500lb. of thrust. The ...

... tons (Danbury). Many people use the words concrete and cement interchangeably, but they're not. Concrete is to cement as a cake is to flour. Concrete is a mixture of ingredients that includes cement but contains other ingredients also (Day 6- 7). Portland cement is produced by pulverizing clinker consisting essentially of hydraulic calcium silicates along with some calcium aluminates and calcium aluminoferrites and usually containing one or more forms of calcium sulfate (gypsum) as an interground addition. Materials used in the manufacture of portland cement must contain appropriate proportions ...

... know the four major atmosphere levels on earth. The troposphere which is between zero and fifteen kilometers in altitude and has tempera- ture ranges from two hundred to two hundred ninety kelvins. The second is the stratosphere which ranges from fifteen to approxi- mately fifty kilometers in altitude and has temperature ranges from two hundred to two hundred fifty kelvins. The third level in the atmosphere is mesosphere. This level ranges from fifty to eighty-five kilometers in altitude and has temperature ranges between one hundred eighty and two hundred fifty kelvins. Finally, the thermosphere is the final leve ...

... from the original personality. Such things as temperament, outlook, handwriting and bodily gestures will usually vary. Even the name of the individual will generally change when a personality switch occurs. When a personality switch does occur, the subject's thoughts, feelings and memories are split from the conscious' awareness and control. The condition usually develops as a way of coping with painful and disturbing experiences faced in the individuals early life, such as child abuse, or if an extremely violent act has traumatized the person. Many personality disorders like Multiple Personality Disord ...

... complexities of organisms, and the great expanses of the Universe. Creationists believe that God (or some form of deity) Created the Universe by divine power, and that the above mentioned complexities could only be achieved by a Supreme Being. The age of Mars has been reported to be between 3.6 billion and 1.3 billion years old, "depending on who you ask" (Erjavec, 1). These ages come from the estimated ages of meteorites found on Earth that are believed to have originated on Mars (Meteorites from Mars, 1). The meteorites were dated using radiometric dating methods (Erjavec, 1). The most widely accepted ...

... this is that data is written to DVD with a smaller laser than a CD, which makes it possible to store data more efficiently. The storage capacity of DVD is so great that over 95% of all feature length films can be stored with room to spare, and also fast data access enables you to read from DVD the same as a hard-disk drive. The best thing of all about the DVD-ROM drive is the fact that it is backward compatible with standard CD-ROM and CD audio discs. DVD-RAM DVD-RAM stands for Digital Versatile Disc - Random Access Memory, and is the approved format by the Official DVD Forum. DVD-RAM are dual sided and can ...
