... in the reactor core. Above the reactor core there is a 5 foot thick lead plate and above that there is a meter thick floor composed of iron, barium, serpentine, concrete, and stone. The exploding steam fires the floor up like shrapnel. The metal plate goes through the four foot thick concrete roof like butter and reaches and altitude of sixty meters. You can hear ripping, rending, wrenching, screeching, scraping, tearing sounds of a vast machine breaking apart. L. Ray Silver, a leading author who covered the disaster at Chernobyl, said that within the core, steam reacts with zirconium to produce that first explosive in nature’s arsenal, hydrogen. Near-molten ...

... atmosphere called the coma. This becomes at least the size of our planet. With the comet going so fast, these materials are forced behind the comet, forming a long tail of dust and gas. Comets are cold bodies. We see them only because the gases they are composed of glow in the sunlight. All comets are regular family members of the solar system family. They are bound by gravity to a strict path around the solar system. Scientists believe that all comets were formed of material, originally in the outer part of the solar system, which did not become incorporated into planets. This material is from when the planets just started forming. This makes comets an e ...

... of viruses. Part one As stated by Prescott, Harley and Klein (1990) microbiology is the study of organisms that are usually too small to be seen with the naked eye. According to Jenson and Wright (1989) a pathogen is a disease-producing organism. They also describe microbes as organisms that are often too small to be seen without the aid of a microscope. Microbes, also known as microorganisms, can be broken down into four classifications that are bacteria, viruses, fungi, and protozoa. Prescott, Harley & Klein (1990) describe bacteria as prokaryotic cells (cells that lack a true membrane enclosed nucleus). Bacteria are both small and simple in ...

... are lighting the burner. When it is lit you will see a yellow flame. Then you would take the evaporating dish and put it in the flame for a few minutes. To see what would be collected on the dish. after you do that. Then you turn the barrel until you can’t see the yellow flame anymore. Then put the dish in the hottest part of the flame and see what happens. After you do that. You would cut off the burner by closing the needle value and closing the barrel. Then you would cut off the gas. In the conclusion the hottest part of the flame was the top part of the flame, and the coolest part of the flame was the blue cone in the middle. Soot was on the bottom of the di ...

... environmental concern - pollution. Pollution is so widespread throughout our world that it is overwhelming. Drinking water supplies are contaminated with runoff from nearby factories and even with pollutants from our own backyards. Demands of skyscrapers and condominiums wipe out our decreasing rainforests. This drudges wildlife from its natural home and into the havoc that is ours. Millions of acres of beautiful land are destroyed daily to satisfy the needs of mankind. But has anyone contemplated the needs of our wildlife? When their homes are incinerated, where do they run for shelter? Where will wildlife obtain its food and oxygen if the sources are g ...

... is to define the problem to be remedied. If we can not understand the problem, how are we to know what needs to be fixed. Unfortunately, implementing policies on air pollution has the politically undesirable effect of having extensive economic consequences on all sectors of the economy. Therefore, those policies which lead to the development of an ecosociety must be aimed at having the greatest environmental impact while creating minimal economic distortions. For the purpose of this essay, pollution shall be identified as follows "...the deliberate or accidental introduction to the environment of contaminants, in the form of either wastes or products ...

... in Florida, where there are breeding sanctuaries. The bald eagle makes its nest with a bulky platform of sticks in a tall tree, and normally has between 2-3 white eggs per season. The golden eagle has the scientific name of aquila chrysaetos and is named for its golden appearance. It is a member of the hawk family. It has a wingspan of six and a half to seven and a half feet, and can live to be thirty or more years old. The adult golden eagle is evenly dark below, or with a lighting at the base of its tail. An immature golden eagle shows a white flash in the wing at the base of the primaries, and a white tail with a broad dark terminal band. The g ...

... equaled Athena's skill in a contest, and in response to Athena's anger she hanged herself. In belated remorse Athena changed the body of Arachne into a spider and allowed her to retain her weaving skill. My first selection is the brown recluse spider. The brown recluse spider (Loxosceles reclusa) is a poisonous spider in in the United States. Its mostly found from Kansas and Missouri, south to Texas, and west to California. Found in sheltered places indoors and outdoors it is about 10 mm (.4 in.) long and has an orange-yellow body with a dark violin-shaped design on its back. Its bite isn't usually fatal to humans, the venom destroys the skin and it ma ...

... not for inhaling. Some teenagers think inhaling helium at parties is fun. But what they don't know it is also fatel. An aspect of inhaling is a person may lose consciousness due to asphyxia (oxygen deprivation). During the exchange of gases in the normal breathing process, the blood stream absorbs oxygen from air in the lungs, while carbon dioxide passes from the blood to the air. When you hold your breath, the exchange of gases slows, as "stale" air in the lungs is no longer replaced by "fresh" air. Oxygen is actually removed from the blood stream during the exchange of gases. depending on how completely oxygen is replaced by helium, you may lose conscious ...

... when it is at it's purest state. The strength of aluminum is increased by alloying it with other metals and elements. Aluminum is one of the best conductors of heat and electricity, it also reflects heat and light very well. Aluminum is fond in many Rocks and minerals on the earth's crust. Because aluminum is not very strong and is highly reactivate with Oxygen, water, acids, and bases it is compounded with other metals and elements to from alloys for common uses. In Society Aluminum Alloys are used in many ways because of it's light weight and versatility. As more and more ways are discovered to strengthened Aluminum with other elements more uses have also bee ...
