The Laser

... used for a concentrator was a man- made ruby. It was done by coiling a simple flash tube around a rod, and beaming powerful flashes of light at it. The result was pulses of red laser light. Once they made the device they had to name it. They had think of some word or words to described it. They came up with Light Amplification by Stimulated Emission of Radiation. Using the first letter of each main word they named it laser. The laser had everyone excited. The laser was put through many tests and experiments to see what it could do t ...

Cloning And Embryo Research

... article in Science News Online, “Scottish investigators grew embryo cells of Welsh mountain sheep in the laboratory. During a relatively stable stage of the cell cycle, they transferred 244 of the nuclei to the stripped-down eggs of Scottish blackface ewes” (Adler Par. 8). These nuclei had a full set of chromosomes, so fertilizing the eggs was not necessary. They then gave the eggs an electric shock to “initiate development” (Adler Par. 9). This was done after years of endless research. There was extensive research done in the are ...

Geothermal Energy

... hard to dispose of the waste. While wind and solar power have no waste products, they require enormous amounts of land to produce any large amounts of energy. I believe that may be an alternative source of energy in the future. There are many things that we must take into consideration before can be a possibility for a human resource. I will be discussing some of these issues, questions, and problems. In the beginning when the solar system was young, the earth was still forming, things were very different. A great mass of elements swirled ...

Landfills

... so that the EPA, or Environmental Protection Agency, will be less likely to detect leakage ( 1). Leakage is when chemicals like leachates and other harmful materials that result from decomposing trash begin to leak out of the . When are located near bodies of water and are not properly maintained, chemicals and other materials can leak out and will go into the water which will be extremely hard to clean but will be hard for the EPA to detect. Doing this will allow the companies to save money because they will not have to barrel the leachat ...

Atomic Structure

... as well. Today, all the matter in the universe is viewed as being composed of three kinds of elementary objects: quarks, which make up neutrons and protons; leptons, which include electrons and some similar particles; and bosons, or vector mesons, which include the photons seen as light and which carry the electromagnetic force. Some scientists suggest that leptons and quarks may actually be the same object but in different states. Bosons, too, may be this same object but in still another state. The everyday world is made of molecules. B ...

Darwin's Theory And Modern Genetics

... stable in size, except for seasonal fluctuations.” Third, “Natural resources are limited.” Fourth, “Individuals of a population vary extensively in their characteristics; no two individuals are exactly alike.” And last, “Much of this variation is heritable.” This process of eliminating certain parts of a population is natural selection. Studies were being done during Darwin’s findings that indicated there was a “gene” associated with certain characteristics. Mendel’s pea plants proved there was a way of artificia ...

Geography Examine The Reasons For Inner City Initiatives And

... the re-development schemes were necessary. When launching the scheme Thatcher said “In partnership with the people and the private sector, we intend to step up the pace of renewal and regeneration to make our inner cities much better places to live, work, and invest”. The inner city programme specified 6 aims: - to enhance job prospects and the ability of residents to compete for them - to bring land and buildings back into use - to improve housing conditions - to encourage private sector investment - to encourage self-help and i ...

Breast Cancer In Women

... this is indeed an issue that needs attention as early in life as possible. Doctors who work with breast cancer patient are now recommending that women as young as 15 and 16 years old should start with self-examination. But how effective is the self-exam, and other forms of early detection, and does it really help to save women from the disease? This is a question I hope to address in the following research. Self examinations are the most commonly used tests used for detecting breast cancer among women today. The self exam is a simple ...

Alcoholism 4

... of plant products such as fruit grains. Gin, Vodka, Whiskey, and other hard liquors, require a further process known as distillation. The active chemical ingredient in beer, wine, and other alcoholic beverages is ethyl alcohol. Ethyl alcohol is a potentially addictive drug and a depressant of the central nervous system (Kestler 6). Alcohol acts as a sedative and as an anesthetic, reducing nerve transmissions and impulses to the central nervous system. This depresses mental, motor, and vital functions such as pulse rate, respiration, ...

Nuclear Power

... that emit energy for a period of time that varies with the isotope. During this active period, while the atoms are 'decaying' to a stable state their energies can be used according to the kind of energy they emit. Since the mid 1900's radioactive wastes have been stored in different manners, but since several years new ways of disposing and storing these wastes have been developed so they may no longer be harmful. A very advantageous way of storing radioactive wastes is by a process called 'vitrification'. Vitrification is a semi-contin ...

Blood Doping

... information is needed to fully understand exactly what can do for an individual. In order for muscles to perform, they need a ready supply of oxygen. During high intensity exercise, oxygen is depleted and the body can not get enough oxygen to the muscle in order for them to perform their optimal potential. This lack of ability to get oxygen to the muscle is called oxygen debt and results in lactic acid being formed. Lactic acid is a waste product of anaerobic cellular respiration within the muscle tissue, which can cause muscle sourness ...
