... 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 message was being sent. This was good because ...

... include situations where a terminally ill patient is unable to consent as justifiable, because it resolves a hopeless situation. Conversely, even with this gradation, some opponents to euthanasia believe that voluntary, passive euthanasia is the same as suicide; involuntary euthanasia is considered to be murder. Because euthanasia poses classic dilemmas as to its morality, it is not surprising that many issues arise in the legal and medical arenas. In law, the resolution of a particular case cannot always be applied to resolve another. In the medical realm, interpretation of medical doctrine concerning treatment of terminally-ill patients can result in entirely ...

... States in World War II. After the war, production of such weapons and the development of a more destructive bomb, the hydrogen bomb, caused worldwide concern. The atomic bomb was a bomb with great explosive force from the sudden release of nuclear energy through the fission, or splitting, of heavy atomic nuclei. The first atomic bomb was tested by the United States near Alamogordo, New Mexico. In the final stages of World War II, the U.S. dropped atomic bombs on Hiroshima and on Nagasaki three days later to force Japan to surrender. The explosion produces great amounts of heat, a shock wave, and intense neutron and gamma radiation. The region of the e ...

... water source, there are many complications. For example, it is a resource that is difficult to assess since it is not directly visible. Therefor with out complicated measurements, it is hard to say how much water there is left in your well. It is also difficult to tell where exactly the source of recharge for your well is. Thus if an area near your well becomes polluted, the pollution may seep into the groundwater feeding your well. The purpose of this project is to explore the subject of groundwater, its place in the water cycle, how it seeps through the ground and how it accumulates in underground pockets called aquifers. The project will also examin ...

... the individual is himself an alcoholic, is the family member of one, or has been the victim of an alcohol related crime. In spite of the dangers alcohol presents,it is still in countless social cirles. Alcohol penetraes all ages, educational, occupational, and socioeconomical boundaries. Each year it is estimated that ten percent of all deaths are related to alcohol abuse. Am astonishing fifty percent of all major automobile accidents, and murders are associated with alcohol. On and on the statistics point to the enormous dangers of alcohol, yet it is a legalized drug. As bleak as this problems seems to be on society as a whole, it is also rueful for the poo ...

... (NOAA). The EROS Data Center (EDC) has managed the Landsat data archive for more then two decades. It provides an impressive collection of information about the Earth’s land surface. The SPOT satellites carry two High-Resolution Visible (HRV) sensors capturing visible and near-infrared radiance data with multispectral and panchromatic scanning capabilities. The multispectral mode captures data in three bands in the following spectral ranges: .50-.59, .61-.68 and .79-.89 micrometers. The three bands are co-registered and have a ground resolution of 20m. The panchromatic mode images data in the spectral range .51-.73 micrometers at a sampling interval ...

... against it. As a result the star collapses. A star that once had eight times as much matter as our sun and was 1,000,000 miles across, becomes a sphere only ten to fifteen miles across. As the star collapses, very small particles (called neutrinos) escape into space. After the star becomes a very small sphere, it explodes like a giant nuclear bomb and becomes a billion times as bright as our own sun. All kinds of matter and radiation are blasted into space. This matter and radiation travels through space at nearly the speed of light (186,000 miles per second) Now, if one of these supernovae were to occur within about 130 light years of Earth, some scientis ...

... are destroyed, virus infection can cause permanent paralysis. When nerve cells in respiratory centers, which control breathing, are destroyed, the victim must be kept alive by an iron lung (see Artificial Respiration). For every paralytic case of myelitis, however, there may be 100 nonparalytic cases. Treatment Because no drug developed so far has proved effective, treatment is entirely symptomatic. Use of moist heat coupled with physical therapy to stimulate the muscles was first initiated by the Australian nurse Elizabeth Kenny, and antispasmodic drugs are administered to produce muscular relaxation. In the convalescent stage, occupational therapy is used. Disea ...

... is caused by the increase of carbon dioxide in the Earth's atmosphere, while other scientists believe that the health threat caused by global warming is due to an unusual interaction between cosmic rays and clouds as well as other natural occurring events. The National Weather Service announced that 1998 was the warmest year (on record on average, around the world). A recent tree-ring study indicated that this is the warmest decade in six hundred years (Allen & Herreid, 82). Undeniably, the weather is getting warmer. According to an article in The Economist, a conservative newsmagazine, "The sea is warming, the plankton dying; floods are sweeping the land. In ...

... This happens because the extra neutron made it unstable. This produces more neutrons that bombard more Uranium nuclei, causing a chain reaction that produces an enormous amount of energy. The problem is the nuclear waste that is produces. It is very radioactive and will not become stable for a very long time. Such a harmful substance is a great health concern and needs to be disposed of. Another problem is the energy it needs. It uses an element that is hard to find and which will eventually run out. Also, the reaction cannot be easily stopped and if it can't be stopped, a nuclear meltdown can occur. This is a serious environmental concern. Fusion is dif ...
