- 6201: To What Extent Does Acid Precipitation Affect Annelids?
- ... and Hall) Earthworms are easily used for experimentation by researchers because they are "widely distributed, familiar organisms, which are readily and cheaply available in large numbers." (Pierce, et. al, (Sep, 1988 Volume 70) Science Notes, School Science Review.) In soils of pH less than 5, earthworms are usually scarce, and soil breakdown is usually slow, making a "deep layer of slowly decomposing plant remains." (Pierce, et. al, (Sep, 1988 Volume 70) Science Notes, School Science Review.) This is a very obvious sign of wether or not earthworms are present, and more often than not, the pH range can be determined on sight. If you look through soil and see ...
- 6202: Could Air Pollution Have A Negative Impact On Water Quality?
- ... does breakdown, it turns into photomirex, which also can have harmful health effects. It was formerly used widely for fire ant control. These insecticides need to be monitored because they are bioaccumulative. Levels may be high in some predatory fish and mammals because toxaphene accumulates in the bodies of those exposed to it. Toxaphene-like substances have been found in the Great Lakes ecosystem. It is also noticed that mirex is ... of exposure to airborne pollutant. For those people using the lakes for occupational or recreational purposes, dermal exposure to water borne chemicals and microbes is relevant. It is clear that occupational or accidental exposure to high levels of certain environmental contaminants discussed in this paper pose a risk to human health. While the exact nature and the extent of health risk from exposure to environmental levels of these contaminants are unclear ...
- 6203: Marilyn Monroe: Suicide or Murder
- ... death. I have chosen two very important references. These references have facts leading up to the very moment she died. Phone records, visitors, etc. It's very hard for me to believe that someone so high on life and talking about her new marriage to Joe Dimaggio on August 1, just three days before her death, would commit suicide. The coroner said Marilyn was laughing and chatting on the telephone with ... the actress's respiratory infections and chronic stage fright delayed shooting of her last movie from the start. Then on May 19, as the following excerpt begins, Marilyn traveled to New York City---despite a high fever and threats from Fox that she could be fired for any more absences---to sing Happy Birthday at a democratic fund raising tribute to President John F. Kennedy. Not present was The First Lady ...
- 6204: Polymers
- ... the first synthetic polymer in 1862. John Wesley Hyatt, an American, was the first person to produce a useable polymer two years later. He named the product celluloid. The prime virtue of polymers is a high strength-to-weight ratio. Industrial-strength polymers surpass titanium in tensile strength. To add strength and improve flexibility, polymers are sometimes fortified with short-fiber additives, mostly fiberglass. This is known as a polymer composite ... and widespread use of polymers, scientific understanding is still sketchy. Polymer development has occurred through trial and error. Scientific shortcomings are becoming more apparent in the search for polymers that can meet the demands for high technology of today. The new study is on the microstructure of polymers while still in a liquid state. The purpose is to learn how the solid-state structure is developed. The ultimate goal is to ...
- 6205: Model Train Building And Compu
- ... and with all these flashy new selling points of use of a Personal Computer, how could hobbyist in this field not want to become involved? One of the leading factors driving the trend toward these high-tech trains is the growing power and falling prices of the parts. Computer chips and memory that once cost hundreds of dollars can now be had for a fraction of the cost. As the price of personal computers falls, so does the price of software and components for the home user making the appeal to there use even stronger. The growing use of high-tech components in traditional train building brings, A blurring of the lines between what is a software product and what is a toy product, says Lego spokesman John Dion. Regardless if the hobbyist is an ...

Another issue that I believe has also lead to the breakdown of family life in South Africa is the high rate of extra martial affairs between migrant labour couples.

- 6207: The Infinity Mirror
- ... it is obviously full of metaphors on the basic belief of our society that everything must be forced into a plausable category, fit for inclusion into the human race. Tularecito should never have gone to school. He would have been happy living at home, simple as he was. In the end society takes Tularecito and makes him a monster. Since monsters are not allowed into human society, Tularecito goes looking for ... belief in fantasy. Tularecito creates another hole, and waits for his fantasy to show. Tularecito has only one flaw. He believes that what he created should not be destroyed. Whenever this happens, should it be school, work, or fantasy, Tularecito defends his creations with the only thing he can understand, violence. It is not like true, calculated violence, but very much like a motor nerve reaction. He reacts with pure emotion ...

- ... up in Seattle. Their father, William H. Gates II, is a Seattle attorney. Their late mother, Mary Gates, was a schoolteacher, University of Washington regent and chairwoman of United Way International. Gates attended public elementary school and the private Lakeside School. There, he began his career in personal computer software, programming computers at age 13. In 1973, Gates entered Harvard University as a freshman, where he lived down the hall from Steve Ballmer, now Microsoft's ...
- 6209: Chaparral
- The chaparral is a major ecosystem and vegetation type composed of woody shrubs that form a dense thicket about 3 to 13 ft high. The species that live in the chaparral are adapted to very dry summers and mild rainy winters. The plants grow in extensive, but discontinuous stands on hillsides and mountain slopes from south-central Oregon southward ... are the chamise chaparral, scrub oak chaparral, ceanothus chaparral, manzanita chaparral, desert chaparral, and insular chaparral.

Two years later he entered the Luitpold Gymnasium and after this his religious education was given at school. He studied mathematics, calculus in particular, beginning around 1891. Many people did not know that Einstein would be as successful as he came out to be. In 1895 Einstein failed an exam that would have allowed him to study for a diploma as an electrical engineer at ETH. After failing the exam, he got excepted in to a lower class school. In 1905 Einstein showed how mass and energy were equivalent. In 1921 he received the Nobel Prize for his 1905 work on the photoelectric effect. In 1928 he passed out because of being overworked which ...
