... low intensity to raise the threshold of the skin to pain. Studies suggested this therapy is applied to conditions such as ulcers, traumatic or burn wounds, osteoarthritis, and cancer. Electrical stimulation is simply the application of electrical pulses to the body, whether it is for function or therapy. The classical and common example is that of the cardiac pacemaker. The range of clinical uses of electrical stimulation has and is growing wider and includes: pain relief (often known as TENS - Transcutaneous Electrical Nerve Stimulation), maintaining or increasing range of movement, muscle strengthening, facilitation of voluntary motor function, and orthotic train ...

... about the facts on deforestation and to express my opinions about deforestation. There are approximately 3 400 million hectares of forests in the world, nearly 25% of the world's land area. Close to 58% of the forests are found in the temperate/boreal regions and 42% in the tropics. For about a millennium, people have benefited from the forests. Forest products range from simple fuelwood and building poles to sophisticated natural medicines, and from high- tech wood based manufactures to paper products. Environmental benefits include water flow control, soil conservation, and atmospheric influences. Brazil's Amozonia contains half of the world's tropical rain ...

... histories show heart damage. Inflated lungs and brain damage have also been observed from lightning fatalities. Loss of consciousness, amnesia, paralysis and burns are reported by many who have survived. Deaths and injuries to livestock and other animals, thousands of forest and brush fires, as well as millions of dollars in damage to buildings, communications systems, power lines, and electrical systems are also the result of lightning. Finally, the threat of lightning causes many work stoppages and lost production increasing the time and cost required to prepare NASA spacecraft for flight. Benjamin Franklin performed the first systematic, scientific study of l ...

... ideas, they came across Mendel's results" (14). Their data agreed, and with this a new science was born - the science of Genetics (15). Due to modern medicine, such as antibiotics and rehabilitation, many genetic diseases have been allowed to survive. In nature, these diseases would not have survived to the extent that they do now. Advances in science and medicine have allowed these problems to thrive. Further advances in science may be able to terminate genetic diseases through cloning. Genetic problems have plagued the United States for centuries. Genetic diseases and mutations are more prevalent in today's world than ever before, due to advances in medic ...

... would only annihilate with ordinary water, and could safety be kept in (say) an iron container. This is not so: it is the subatomic particles that react so destructively, and their arrangement makes no difference. Scientists at CERN in Geneva are working on a device called the LEAR (low energy anti-proton ring) in an attempt to slow the velocity of the anti-protons to a billionth of their normal speeds. The slowing of the anti-protons and positrons, which normally travel at a velocity of that near the speed of light, is neccesary so that they have a chance of meeting and combining into anti-hydrogen. The problems with research in the field of an ...

... have the same amount of sun as the sun makes its way north. Before the vernal equinox the sun hits the northern surface at an angle instead of hitting it directly. By hitting the earth's surface at an angle there is not as much radiation warming the surface. As the earth rotates and the sun moves further north the temperature increases and the weather turns warmer. During the three months of spring the sun continues to move north and warming the earth more efficiently. At around June 21st the sun is directly facing the tropic of cancer. At this time the movement north comes to a halt and the earth's surface is at its warmest point, the summer solstice. I ...

... 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, fiber optic technology has almost become a necessity in everyday business. Because fiber optics can simultaneously transmit two audio signals across a single fiber optics cable without interf ...

... kind of medical misfits there will be in the future, using this life-saving technology to their own personal, perhaps evil, advantages. Dealing with politics, Bioengineering has opened a whole new door pertaining to the military, whose use of it may create an ultimate destruction. The alterance of nature is un-natural, and creates an unbalancement in life. When we use this technology towards the wrong side, we may all be burned. You see, Biotechnology has the ability to altar what diseases we humans are susceptible to, and when scientists create something to eliminate immunities to diseases, it may result in a mass destruction of the evolved living being known as ...

... in each cell of their bodies instead of the usual number of 46. This extra sex (X) chromosome causes the distinctive make-up of these boys. All men have one X chromosome and one Y chromosome, but sometimes a variation will result in a male with an extra X. This is and is often written as 47,XXY. There are other, less common variations such as 48,XXYY; 48,XXXY; 49,XXXXY; and XY/XXY mosaic. All of these are considered variants. The major effect of the extra X chromosome in boys with seems to be the function of the testes. The testes produce the major male sex hormone testosterone and the amount of this hormone may be decreased in boys with . When these boys re ...
