... Earthquake, “vibrations produced in the earth's crust when rocks in which elastic strain has been building up suddenly rupture, and then rebound.�(Associated Press 1993) The vibrations can range from barely noticeable to catastrophically destructive. Six kinds of shock waves are generated in the process. Two are classified as body waves-that is, they travel through the earth's interior-and the other four are surface waves. The waves are further differentiated by the kinds of motions they impart to rock particles. Primary or compressional waves (P waves) send particles oscillating back and forth in the same dire ...

... is not only stored digitally, but also has been created and manipulated with computers. Viewers are witnessing the results of all this in the form of stories and experiences that they never dreamed of before. Perhaps the most surprising aspect of all this, however, is that the entire digital effects and animation industry is still in its infancy. The future looks bright. How It Was In the beginning, computer graphics were as cumbersome and as hard to control as dinosaurs must have been in their own time. Like dinosaurs, the hardware systems, or muscles, of early computer graphics were huge and ungainly. Th ...

... who is afflicted with the "sleeping sickness" disease that reached epidemic proportions during that specific era. Like many others who contracted this illness, Leonard and those like him were often misdiagnosed and eventually placed in mental hospital facilities because of their apparent vegetative state. Doctors who worked on the earlier cases believed the patients mental faculties to have been destroyed by the illness. Dr. Sayer (Dr. Oliver Sacks in real life) discovers that certain vegetative patients reacted to outside stimuli, such as a pattern on a floor, a tossed ball, or a television with a maladjusted verti ...

... as well as aid for body malfunctions. Genetic engineering is a fundamental tool for leading the world of medicine into the future; therefore, it is crucial to continue research in this field. Today's research in genetic engineering is bringing about new methods for curing and treating major medical illnesses. The Human Genome Project has allowed geneticists to map the genes of human beings. This project is far from complete, as the DNA sequence of humans is extremely long, yet it will eventually show geneticists which genes are responsible for certain inherited diseases. Identified genes could be repaired, r ...

... fertilised egg. Likewise, many tumours are clones, derived from one aberrant cell which no longer obeys the normal rules of growth control. The offspring of organisms which reproduce asexually, like corals, are also clones; as are identical twins produced by the natural, or sometimes deliberate, splitting of a single embryo. Members of a clone are genetically identical and genetic identity has given cloning an additional more technical meaning: namely the procedures used to create a new organism whose genetic constitution is a replica of another existing individual. Such a feat can be achieved by substituting ...

... utilizingthe heat stable DNA polymerase from a thermophilic organism." (from http://www.genes.com/pcr/pcrinfo.html) Dr. K.Mullis recently received the Nobel prize for inventing the technique. This is how they go about doing this: They first get their small DNA sample. Then they mix all the chemicals (this includes the primer, etc). Then they have to run it through the PCR machine. Here is a (rather detailed) description of the process: "The cycling protocol consisted of 25-30 cycles of three- temperatures: strand denaturation at 95degC, primer annealing at 55degC, and primer extension at 72deg C, typica ...

... and is currently one of the world's most popular fabrics. It is fairly heavy and is made with a blue cotton warp and a white cotton filling (Groilers, 1996). The thermal underwear is duofold, with an outer layer made of 65% cotton, 25% wool, and 10% nylon, and an inner layer made of 100% cotton. It's the winter again and the weather is becoming colder. Each morning many people wonder what to wear to stay as warm as possible, but they aren't sure which material will keep them warmest. The experiment was chosen to see which clothing insulator retains the most heat. "Insulation is material that protects against h ...

... to provide some background information on what is known about leprosy and then attempts to investigate certain aspects of the disease that are unknown. A description of the classification, mechanism of infection, transmission, distribution, and treatment of the disease will be provided. After reviewing the background material, a great deal of questions may arise as to how exactly this disease is spread from person to person and what conditions promote infection. For example, one may wish to investigate the following: 1) Mycobacterium leprae as yet to be cultured in laboratory media? Why? 2) Why is leprosy so pre ...

... teaching, he went on to study natural philosophy. He became intrigued by atomists and the theory that all things in nature were made up of particles of matter, also known as atoms. He then returned to Woolsthorpe and continued to study light, gravity and mathematics. These studies eventually lead him to some of the greatest discoveries in the history of science. In science his main discovery was that when white light passed through a prism, it was broken up into a broad spectrum of colors. When that spectrum was shone back through another prism that spectrum became a white light again. Next he passed a single ...

... tiger subspecies, and the Siberian tiger has the fewest stripes. Tiger stripes are like human fingerprints; no two tigers have the same pattern of stripes. The tiger's head often carries the Chinese mark of wang or king on the forehead. Most tigers have an orange coat with dark brown or black stripes accented with white. Tigers that live in cold climates (Siberian tigers) have thicker fur than tigers that live in warm climates. A tiger's tail is 3 to 4 feet long, about half as long as its body. Tigers use their tails for balance when they run through fast turns. They also use their tails to communicate with other t ...
