Anti-Matter
Words: 1226 - Pages: 5.... as a negative mass.
The second and more subtle mistake is the idea that anti-water
would only annihilate with ordinary water, and could safety be kept in
(say) an iron container. This is not so: it is the subatomic
particles that react so destructively, and their arrangement makes no
difference.
Scientists at CERN in Geneva are working on a device called the
LEAR (low energy anti-proton ring) in an attempt to slow the velocity of
the anti-protons to a billionth of their normal speeds. The slowing of
the anti-protons and positrons, which normally travel at a velocity of
that near the speed o .....

Mini-Research

the electrodes were made of or the kind of gas in the tube. In 1909, RA
Millikan, an American scientist, measured that charge. All electrons are found
to be identical no matter their source or the method of liberating them from
matter. From the values of e/m, and e, the mass of an electron was calculated
to be .00055 amu.
PROTON- Eugeen Goldstein used a Crookes tube with holes in the cathode, and
observed that another kind of ray was emitted from the anode and passed through
the holes. He discovered this in 1886. In 1889, William Wien showed these rays
to be positively charged .....

Basic Discription Of Microbiology
Words: 1992 - Pages: 8.... 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 structure; they usually are between o.5 and 5cmm yet they have many .....

Genetic Engineering: A Leap In To The Future Or A Leap Towards Destruction
Words: 3028 - Pages: 12.... field of medicine. It will usher in a world where gene defects, bacterial disease, and even aging are a thing of the past. By understanding genetic engineering and its history, discovering its possibilities, and answering the moral and safety questions it brings forth, the blanket of fear covering this remarkable technical miracle can be lifted.
The first step to understanding genetic engineering and embracing its possibilities for society is to obtain a rough knowledge base of its history and method. The basis for altering the evolutionary process is dependant on the understanding of how individuals pass on characteristics to their offsp .....

Klinefelter Syndrome
Words: 813 - Pages: 3.... completed, however, chromosomes pair with their corresponding chromosomes and exchange bits of genetic material. In women, X-chromosomes pair, in men, the X and Y-chromosomes separate, and meiosis continues. Otherwise it is not something that happens by the law of nature in which you are randomly chosen in its specific frame of how many times it happens, whom it effects, and how it happens. There is really no specific frame in which it invariably happens. It is known through that it happens during the process of meiosis in which chromosomes split.
WHO IT AFFECTS???
Klinefelter Syndrome only occurs in males. This is so because female .....

New High-speed Connections Will Change How We Work And Play
Words: 860 - Pages: 4.... been limitations to how fast data can travel over existing copper telephone lines. Using an analog modem, data is translated from its digital form to an analog signal, to travel over the telephone lines. Once it gets to its destination, the data is converted back into its digital form. Line noise is a result of data being transmitted as an analog signal. The FCC imposed limitations, decades ago, to minimize the amount of line noise that was allowed. This law was imposed long before the PC ever existed. However, it directly affects how fast we can access the Internet today, at speeds of only 53kbps. Even that connection speed is theore .....

Are UFOs Real?
Words: 1817 - Pages: 7.... or mentions one breath of usually spreads so quick and gets so out of hand it is almost as unbelievable as a UFO being real. Another odd fact about UFO's is that if they are suppose to be out there somewhere why did the government stop research on them? Maybe they got tired of spending money on something that was getting them nowhere. The overall and main question that has been asked for many, many years is, "Are UFO's real?' This is simply one question that can not be answered with yes or no but only answered with opinion. My opinion as to whether or not UFO's are real would have to be no. There is simply no believable evidence that h .....

Feeding Yeast
Words: 735 - Pages: 3.... For the actual experiment, I used four (4) ICB root beer bottles, 4 balloons, yeast and the yeast foods- corn syrup, flour/water, gelatin, and grape juice. The yeast was a solution-6¾ teaspoons of yeast per cup of very warm (105° to 115°) water. Into all four bottles I put four tablespoons (tbsp.) of the yeast solution. Put ½ cup of corn syrup into bottle one, along with the yeast solution. Into bottle two goes ½ cup of water and ½ cup of flour, and the yeast solution. Next, mix the gelatin according to directions on the package, about one-tablespoon of powder to ½ cup of water. The ½ cup of the gelatin goes i .....

Ozone Depletion In The Antarctic
Words: 1703 - Pages: 7.... refrigerators, and spray can propellants mainly in the Northern Hemisphere. CFC's disperse throughout the stratosphere and breakdown to release chlorine. Chlorine by itself is a very stable compound, but when in the stratosphere it binds to and destroys ozone. This is a cyclic process and therefor means that one chlorine can destroy many ozone molecules (Figure 1.2)
During the winter in the Antarctic the circumpolar vortex, which is a strong westerly circulation around the continent, builds in the stratosphere. This phenomenon causes the interior of the stratosphere to be cut off and the temperatures drop below -800C. This results .....

Forensic Psychology
Words: 860 - Pages: 4.... greatly, but all areas deal with some interaction of psychology and the law. For this reason, the field is often referred to as Criminal Psychology. Forensic psychologists are most known for working in the courts but they can also work in work in a penal institution, state mental hospitals, law enforcement agencies, or a private practice (The Page").
Forensic psychologists also provide treatment services. These include counseling for adults and children involved in divorce proceedings and anger management counseling ("Psychology Information Online" 1998).
Forensic psychologists help a lot with family issues. Some examples of the services fo .....
