advantages and the disadvantages of genetic cloning. It speculates how our
future will improve due to the technologies we are developing, and also the
biggest drawbacks which might come from it.
The last part of the paper, is the explanation of complicated terms used
in this paper. The terms which will be explained are printed in bold terms
throughout the paper. This section, the glossary, is like the ones which

The Y2K Problem
Number of Words: 770 / Number of Pages: 3
... is assumed to be '19' and the program's function is to figure out how old you are. If you were born in 1958, then in 1999 this program will calculate your age as 99 minus 58, or 41. That's fine, but what happens when the century rolls over to '20' in the year 2000? In this program, the year will appear as '00' but the century will still be assumed to be '19' -- so the program will calculate your age as 00 minus 58, or -58. Then, depending on the program's error-handling capacity, it might abnormally end or otherwise stop running; or it might send the negative age to another program (which might the ...

... solid ozone is violet-black.
Oxygen is very reactive and capable of combining with most elements.
It is essential for respiration of all plants and animals and for

history of oxygen
Leonardo da Vinci suggested that air consists of at least two
different gases. Before then, air was felt to be an element in its own
right. He was also aware that one of these gases supported both flames and
life. Oxygen was prepared by several workers before 1772 but these workers
did not recognise it as an element. Joseph Priestley is generally credited
with its discovery (who ...

Deficiencies In Development Of Cocaine Children
Number of Words: 1762 / Number of Pages: 7
... those of a disruptive child. The underlying truth is: teachers are not able to cope with them on an individual basis and give them more attention.
An initial sign that some children demonstrate is a lack of concentration on virtually every task. Excessive disorganization beyond that of regular children along with being more than just the class nuisance can be characteristics of cocaine-exposed children. While most children are able to stay on task, these children will be easily deterred if given the opportunity. These children tend to exhibit a lack of exploration of the environment which results in ...

Mechanical Energy
Number of Words: 491 / Number of Pages: 2
... Our bodies
do not burst into flames but the perspiration on our skin is a clue to
what is happening.
The movement of the windsurfer has a different explanation.
The windsurfer is propelled along by a sail which collects mechanical
energy from the winds that sweep along the water. This energy has been
produced by the sun which warms the earth's surface and sets the air above
in motion. The sun's heat comes to the earth as a form of radiant energy.
When the heat reaches the surface of the earth, it causes the land or seas
to rise in temperature.
The sun is very hot. Infact, the center of the sun c ...

Evidence Of Technological Change

... have widened across the country quickly, especially the multinational firms. Thus, if technological change is an important determinant of relative demand shifts, one would expect to observe patterns in other industrialized countries similar to those in the United States. Some of the recent studies report results for a variety of old industrialized (OECD) countries that are indeed consistent with the U.S. results (Collechia and Papaconstantinou, 1996; Machin, Ryan and Van Reenan, 1996). These countries vary a great deal with respect to changes in their situations with respect to trade, labor ...

... massive damage occurs. In 1983 the Dow Chemical Company’s factory, a major producer of chemicals, showed contamination from dioxin. Dow undertook a 3 million dollar study of the material. The company announced that Dioxin is less health and life threatening.
High-temperatures are used to reduce the toxicity of waste. These processes use plasma technology to make the waste more environmentally friendly. Plasma treatment reach temperatures up to 1,650o F. In the United States incineration is a primary way to get rid of liquid waste. This process eliminates waste in two stages. One is partially bu ...

... as the ice edge retreated, and North America
inherited a fertile soil base. Soil type is an important factor for which
species of trees can thrive in an area. The general dominant tree species for
temperate deciduous forests are Beech, Ash, Oak, and in our region also Tulip,
Maple, Birch, and Hickory. Developed forests consist of four layers. The layers
are: canopy, sub canopy, shrub, and ground cover. This layering affect benefits
the diversity of the ecosystem by providing a rich variety of habitats. It is a
result of adaptation and competition for sunlight and shows the continuing
process of succ ...

What Is Physics And What Are Its Uses?
Number of Words: 504 / Number of Pages: 2
... Lasers are based
on the physical principle of light, and are devices for the creation and
amplification of a narrow, intense beam of coherent light. New laser
microsurgery can actually alter the shape of the cornea in the eye so the
patient's eyesight can return to normal, and he/she will no longer need those
bothersome glasses. Ultrasound is used in the medical field for destroying
various unwanted substances in the body such as kidney stones. Ultrasound uses
sound waves to dissolve these foreign bodies. If not for physics, ultrasounds
would never have been discovered and utilized. MRI scans, anot ...

Eutrophication is the progressive over-fertilization of water, in which
festering masses of algae's blooms, choking rivers and lakes. Phosphorus
compounds act as a fertilizer for all plant life, whether free-floating algae
or more substantial rooted weeds, and are implicated in eutrophication. Many
countries control phosphate levels, whereas Switzerland has banned the use of
phosphates.
