Melting Pot Theory
Number of words: 401 - Number of pages: 2.... movement, but just down the street from Haight and Ashbury there is a place called China Town. A place placed filled with Chinese Americans, shops and temples that could be easily mistaken for buildings only found in China . In Ohio, one could meet a Caucasian farmer, a African American businessman, an Amish family or even a reporter who has a strong German background all in the same day. So many different people living together in one piece of land. Now, after taking a closer look, no one really melted together to make just one kind of person. But what did t .....

Acting To Save Mother Earth
Number of words: 500 - Number of pages: 2.... paper-making by 95 percent.
Another earth saving habit is "precycling" waste. This means buying food and other products packaged only in materials that will decay naturally or that can be recycled. The idea is to prevent unrecyclable materials from even entering the home. For instance, 60 of the 190 pounds of plastic-especially styrofoam-each American uses a year are thrown out as soon as packages are opened. Be kind to your planet by buying eggs, fast food, and other products in cardboard instead of styrofoam cartons. Buy beverages in glass or aluminum con .....

Uranium
Number of words: 267 - Number of pages: 1.... to mine it at a cheap cost.
Chapter 2
Mining
When uranium is extracted, pitchblende is broken up and mixed with
sulfuric and nitric acids. It then dissolves into uranyl sulfate. With the
addition of sodium hydroxide, uranium is precipitated as sodium diuranate
which is known as the yellow oxide of uranium. To get uranium from
carnotite, the ore must be finely ground and treated with a hot solution of
caustic and potash to dissolve out the uranium, radium, and vanadium. And
after the sandy matrix is washed away, the solution is treated with
sulfuric acid and barium chloride. A caustic alkali solution is .....

Diabetes 3
Number of words: 769 - Number of pages: 3.... to the skin which causes loss of feeling. Sores and deep infections called diabetic ulcers occur because of this.
Pregnancy is affected by diabetes Mellitus. Many changes that take place during pregnancy make controlling blood sugar more difficult for a woman who has diabetes. Changes in the levels and types of hormones produced during pregnancy can cause insulin resistance, increasing the body’s requirements for insulin. Poorly controlled diabetes may endanger the fetus as well as the woman. With proper adjustments in insulin the risks lessen. Diabetes i .....

Nuclear Fusion
Number of words: 2376 - Number of pages: 9.... be 10 times
cooler than just a regular nucleus. Such a reaction is not self sustaining
because the released energy is not readily imparted to other nuclei.
thermonuclear fusion of deuterium and tritium will produce a helium nucleus and
an energetic neutron that can help sustain further fusion. This is the basic
principal of the hydrogen bomb which employs a brief, controlled thermonuclear
fusion reaction. This was also how the car in the Back to the Future movie
worked. It had a much more sophisticated system of producing a fusion reaction
from things li .....

EPA Urges Tough Rules On Arsenic
Number of words: 308 - Number of pages: 2.... that would have to change their filtration systems to meet federal law. The review focused on alternative standards – ranging from as low as 3 parts per billion to as high as 20 parts per billion. Whitman states it is to dangerous to have the arsenic levels over 20 parts per billion.
Person 4- Arsenic occurs naturally in rocks, soil, water, air, plants and animals. High concentration levels are mostly found in the drinking water in the Western states. Long-term exposure to arsenic in drinking water led to cancer of the bladder, lungs, skin, kidney, nasal .....

Tiger Subspecies
Number of words: 562 - Number of pages: 3.... under full protection.
Politicans and bureaucrats seem to be obsessed with numbers and not
trends. Let me illustrate this with tigers. There are frequently requests as to
the exact number of tigers, or a tiger subspecies left in the world. That tells
you that there are people that care. But there are so little tigers left that
we can not even keep track of them. We should look at the trend that the
population is taking, rather than the number as a slice in time. Just as you
might say of a young member of the Hunt family, that they were very wealthy. A
hypoth .....

Genetic Engineering: Correcting The Code
Number of words: 1116 - Number of pages: 5.... engineering should be a known and accepted practice. It is a safe
way to create good quality foods, create new lives, and cure diseases.
In May of 1994, the Food and Drug Administration approved a
genetically engineered tomato called “Flavr Savr”. Many people cringe at
the thought of eating them. These tomatoes, though, are proven better and
healthier even though they are slow ripening. The idea of altering a
plant's traits seems radical and new, but scientists have been doing it for
years by breeding desired qualities into crops (Henkel 10). .....
