In the United Stated alone, there are between 500,000- 750,000 heroin addicts. Hero ...

Cryogenics: Is It Worth Waiting For

... 16- 17). Measurement of temperature is extremely important in cryogenics and the temperatures must be exact. The standard for scientific temperature measurement is the Kelvin scale. On the Kelvin scale absolute zero has a value of zero degrees on the thermometer. In theory no substance can be lowered to or below zero degrees Kelvin or absolute zero. Temperatures in cryobiology range from zero degrees Celsius--water freezes--to just above negative two hundred and seventy three point sixteen degrees Celsius--absolute zero. The word "Cr ...

... name because it moves so quickly across the sky. Mercury has been known since at least the time of the Sumerians.

Since Mercury is a smaller planet, extremely close to the sun, and has no substantial atmosphere, it has the greatest temperature range of any planet or natural satellite in our solar system. The surface temperature on the side of Mercury ...

Deficiencies In Development Of Cocaine Children

... developmental years. Women who use cocaine while pregnant cause a great damage to their children during the developmental years; especially in the aspects of cognitive motor and social/ behavioral deficiencies. Cognitive deficiencies are those that deal with an individual’s thinking and reasoning process. These abilities are seen in the beginning school years, not at birth, but are the subtle characteristics that only through the school environment can be recognized. In a class environment, the deficiencies of a cocaine child are often conf ...

Global Warming

If anything comes from this project, it is a hope that it will shed some light onto the hot topic of with some cold science! occurs when the levels of greenhouse gasses rise and less infrared light, or heat, escapes the earth's atmosphere. Thus, the temperature experienced on Earth begins to rise. Climate change is a part of the Earth's history. There have been dramatic fluctuations in over all average temperature for the past 150,000 years that suggest a direct association with carbon dioxide level ...

The Threat Of Nuclear Energy

... core and in 3 seconds the temperature went from 280 degrees centigrade to 4,000 degrees centigrade. The water that was in the reactor is instantly turned to steam which creates tremendous amount of pressure in the reactor core. Above the reactor core there is a 5 foot thick lead plate and above that there is a meter thick floor composed of iron, barium, serpentine, concrete, and stone. The exploding steam fires the floor up like shrapnel. The metal plate goes through the four foot thick concrete roof like butter and reaches and altitude ...

Klinefelter Syndrome

... xxy instead of the normal How it occurs This syndrome occurs by natural selection in which the condition arises from chromosomal nondisjunction during meiosis in this process, the 46 chromosomes in the cell separate, ulimatiing producing two new cells having 23 chromosomes each. Before meiosis is 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 happ ...

The Destruction Of Red Tides

... Certain blooms of algae are termed red tides when the tiny pigmented plants grow to a great abundance. The term red tide is misleading in the name. "Red tides are only occasionally red, also appearing as orange, brown, and even green. And they never occur literally as tides, which are the rises and falls of the sea." (New York Times: Aug. 27,1997) Some cases of red tides do not show any change in the color of the water at all. This makes a red tide very hard to predict or find. Red tides often occur when fresh water runoff creates a stra ...

Evolution From A Molecular Perspective

... genomes of creatures have been sequenced, and the human genome project is well underway and ahead of schedule. With this new knowledge comes worries, for humans, however. What if the information stored in our genes was available to the public? Would insurance companies and employers base their selections on these traits? Also, with the total knowledge of every sequence of every amino acid chain in a person's genome, couldn't a laboratory perceivably reconstruct an exact copy of, or clone, that person? These are all issues that will ha ...

... prospered tremendously well under a benign atmosphere," (Bates 28). Today, however, major changes are taking place. People are conducting an inadvertent global experiment by changing the face of the entire planet. We are destroying the ozone layer, which allows life to exist on the Earth’s surface. All of these activities are unfavorably altering the composition of the biosphere and the Earth’s heat balance. If we do not slow down our use of fossil fuels and stop destroying, the forests, the world could become hotter than it h ...
