... transfer devices, radiation detectors and a variety of other devices.
Silicon belongs to the group IV in the periodic table. It is a grey brittle
material with a diamond cubic structure. Silicon is conventionally doped with
Phosphorus, Arsenic and Antimony and Boron, Aluminum, and Gallium acceptors.
The energy gap of silicon is 1.1 eV. This value permits the operation of
silicon semiconductors devices at higher temperatures than germanium.
Now I will give you some brief history of the evolution of electronics
which will help you understand more about semiconductors and the silicon chip.
In the ...

... as CFCs, also known as Chlorofluorocarbons, hydrofluorocarbons, and perfluorocarbons. These gases are generated a number of human activities such as fossil fuel combustion, waste disposal in landfills, the use of a refrigerator, numerous agricultural and industrial activities, and the cutting down of numerous forests.
These human practices have already changed the chemical make up of the atmosphere. Between the pre-industrial times and today, we have seen the concentration of carbon dioxide rise 30% in some regions, in particular the northern hemisphere, human practices have increased concent ...

happened at first and then glowing eyes caught their attention. One guy
was killed. The other guy managed to get away and swim for about 200 yards
and then he was down. The men's bodies washed up on shored weeks later.
That's when Chase and Tall Man knew there was something in the water and it
was up to them to figure out what it was. More strange things were
happening. The ocean life began to act strange and Chase couldn't figure
out what that had anything to do with the killings.
Tall Man was a rather large Indian man that had many reasons to be
fearless. The reaso ...

Oceans

... to be in medieval times.”(Heyerdahl) The majority of the world's
population still lives under the misconception that the ocean is a hungry abyss,
eager to devour all their waste. These beliefs, however, are all untrue. The
average depth of the oceans is only a little more than a mile, when in fact,
some lakes exceed this depth rather handily. Although the size of the ocean is
often pondered, the thought that it may one day be gone, is never even
considered.
The vast majority of all life in the ocean, inhabits only 1/25 of these
waters, but it is these surroundings that are in the most danger. ...

Linux Vs Nt

... would go with a Linux machine is $200. In an NT machine, the minimal hardware cost rose up to $1300. This is because NT requires at least a 486 Pentium with 16MB of RAM. Linux can run fine on a 386 computer with only 8MB of RAM.
What do the majority of users need a computer for? Mainly word processing and the use of a database program. An NT user doesn’t have to go with Microsoft Office, but a lot of people do, costing a couple hundred dollars. Linux can run an Office Suite program that is very similar to Office for at least half the cost. Even a free version of WordPerfect 8 is availab ...

Genetic Engineering, History And Future: Altering The Face Of Science
Number of Words: 2968 / Number of Pages: 11
... 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 offspring.
Genetics achieved its first foothold on the secrets of nature's evolutionary
process when an Austrian monk named Gregor Mendel developed the first "laws of
heredity." Using these laws, scientists studied the characteristics of
orga ...

Droughts
Number of Words: 478 / Number of Pages: 2
... is a characteristic of those areas where warm, tropical air masses, in descending to earth, become hotter and drier. When a poleward shift in the west ocurrs, the high-pressure, anticyclonic conditions of the permanently arid regions hit each other on areas that are normally used to seasonally wet low-pressure weather and a drought follows. A southward shift in the western winds causes the most severe drought of the 20th century, the one that struck the African region, Sahel for 12 years starting in 1968.
Statistics indicate that roughly every 22 years a major drought occurs in the United States, the ...

... forces and form a hot core, combined from all the energy of the two gas clouds. This energy produced is so great when it first collides, that a nuclear reaction occurs and the gases within the star start to burn continuously. The Hydrogen gas is usually the first type of gas consumed in a star and then other gas elements such as Carbon, Oxygen, and Helium are consumed. This chain reaction fuels the star for millions or billions of years depending upon the amount of gases there are. The star manages to avoid collapsing at this point because of the equilibrium achieved by ...

... risk for attention deficit
disorders with hyperactivity, fine-motor impairment, and clumsiness as well as more subtle delays in
motor performance and speech disorders. [4] These findings have been referred to as fetal alcohol
effects (FAE).
As recently described, FAS and FAE produce profound cognitive, behavioral, and psychosocial problems that persist to date of follow-up of those affected. In the most comprehensive and far-reaching study to date, Streissguth et al [5] traced the natural history into adulthood and demonstrated the profound, pervasive, and persistent nature of the biopsychosoc ...
