The Human Cloning Controversy
Number of words: 1356 | Number of pages: 5.... to make a headless human? (body parts) Yes, as long as no law exists banning headless humans. Before going into this controversy, some background about what has happened in cloning would be useful. Two astonishing feats have been achieved in the scientific world. One is the cloning of a sheep named Dolly, and the other is the development of headless frog embryos. Dolly was cloned in Edinburgh, Scotland, at the Roslin Institute in July 1996. The headless frog embryos were manufactured in London, England, in October 1997 (this didn't get the same amount of press attention as Dolly). Not only were the time frames different between .....

Global Warming 2 -
Number of words: 642 | Number of pages: 3.... in these fuels was released to the air as carbon dioxide - a gas that traps heat in the atmosphere. Today, for every one of the more than 5.8 billion people on Earth, nearly six tons of carbon dioxide is spewed into the air every year. As a result of our activities, the gas trapped inside the atmosphere has risen by more than 30 percent in the last 250 years. These greenhouse gases which prevent infrared radiation from escaping into space, keep the earth's temperature warm. According to the British Meteorological Office the earth is getting warmer each year - In fact 1995 was the warmest year on record.

Aedes Aegypti
Number of words: 933 | Number of pages: 4.... 1996). The dorsal pattern of white scales on the scutum is in
the shape of a ‘lyre’ with two central based stripes that contrast with the dark scales
present on the insect (Womack 1993,
Russel 1996). Its wings are dark scaled and femur and hind legs are pale scaled for
about three-quarters, and dark scaled for about two-thirds (Russel 1996).
The first through the fourth segments of the hind tarsi are characterized by white rings
and the fifth segment is all white.
Adults can be found in abundance in towns and cities near human dwelling
places., living in trees, herbaceous plants, dim closets, cabinets or ev .....

Fission Or Fusion
Number of words: 1273 | Number of pages: 5.... nuclei such as hydrogen, deuterium, or
carbon. This fact is the basis for the design of practical energy-producing
fission reactors.
In December 1942 at the University of Chicago, the Italian physicist
Enrico Fermi succeeded in producing the first nuclear chain reaction. This was
done with an arrangement of natural uranium lumps distributed within a large
stack of pure graphite, a form of carbon. In Fermi's "pile," or nuclear reactor,
the graphite moderator served to slow the neutrons.
Nuclear fusion was first achieved on earth in the early 1930s by
bombarding a target containing deuterium, the mass-2 isotope of hydrogen, with
hi .....

Technology And The Future Of W
Number of words: 4373 | Number of pages: 16.... of education, industry and a movement to global politics, economics and world government.
In particular this paper will suggest that the Christian Judao work ethic with society’s goals of full employment in the traditional sense is no longer appropriate, necessary or even possible in the near future, and that the definition of work needs to be far more liberal. It argues that as a post market era approaches, that both government and society will need to recognise the effects of new technology on social structure and re-distribute resources, there will need to be rapid development of policies to assist appropriate s .....

Lime Disease
Number of words: 916 | Number of pages: 4.... uses white-footed mice, mosquitoes, and deer as their hosts.
This disease does not discriminate between sex and age; male and female, as
well as old and young are affected. It is widely distributed around the world in the
temperate zones3. A person is infected when a black-legged tick imbeds itself into
them while out in the open in wodded and forested areas. This usually occurs between
the months of May and July. Tick abundance is associated with humidity, temperature,
landscape slope, forested areas with sandy soils, and the extremity of residential
development?.
Generally, lyme disease occurs in stages, which .....

Bovine Spongiform Encephalopathy
Number of words: 2159 | Number of pages: 8.... was the scientists' overall conclusion (Stadthalle, 1993). These
lesions are consistent with the diseases of the more common scrapie family.
Without further investigation, the conclusion was made that BSE was a new member
of the scrapie family (Westgarth, 1994).
Transmission of BSE is rather common throughout the cattle industry.
After the incubation period of one to two years, experimental transmission was
found possible by the injection of brain homogenates from clinical cases
(Swanson, 1990). This only confirmed that BSE is caused by a scrapie-like
infectious agent.
How does the transmission become so readily available a .....

Hurricane Floyd
Number of words: 1228 | Number of pages: 5.... long, narrow regions of low pressure which occur in ocean winds called trade winds. At first, these easterly waves can grow into something called, a tropical depression. A tropical depression occurs when winds are up to 31 mph. Then tropical depressions can be upgraded into a tropical storm if the winds reach speeds of 74 mph or less. Then finally a the storm can be bumped up into a hurricane if the winds reach 75 mph.
The National Weather Service is constantly trying to provide us with data and other information about when and where hurricanes are forming. It has been said that the only way
to reduce the number of fatalities in .....

Disaster Spills Across Bhopal
Number of words: 887 | Number of pages: 4.... assistance, but by then it was too late. At 12:56 a.m., the morning of December 3rd, a faulty valve ruptured, allowing the deadly gas to escape into the atmosphere and cause a huge vapor puff to fall onto silent, sleeping Bhopal (Cush, 30).
Before the release of 40 tons of MIC, Bhopal was a prospering city. The population was growing to about 700,000 people. In India large corporations were encouraged to build there to bring more jobs to the community and raise the economy. So when Union Carbide built their plant in the middle of heavy slums and shantytowns, they were welcomed with open arms.
In the seven years the plant was .....

The Rain Forest
Number of words: 2207 | Number of pages: 9.... fifteen countries, each containing over ten million hectares. Tropical
rainforests receive 160 to 400 inches of rain each year. Although these dense,
damp forests cover just 5 percent of the Earth's surface, they can provide homes
for between 50 and 90 percent of the Earth's plants and animals
(http://www.davesite.com/rainforests/review1.shtml).
Tropical rainforests consist of three distinct layers referred to as the
forest floor, the understory, and the canopy. The forest floor contains very
poor soil which is mainly due to the trees not allowing for ample sunlight to
reach the ground. Because only one to two perce .....
