The Effects Of Hurricane Gilbert
1641 Words - 6 Pages.... Atlantic storm. Causes that contributed to the strength of Hurricane Gilbert include: atmospheric conditions, the category rating, and the proximity of its' eye.
The effects of the hurricane consisted of property damage, economic losses, casualties and some solutions such as insurance and funds. Atmospheric conditions were some of thefactors that contributed to Hurricane Gilbert's intensity. Hurricane Gilbert had extremely powerful winds that reached 160 knots which is about 175 mph and gusts up to 121 mph (Stengel 18). At 10, 000 feet, Gilbert's Counter clockwise winds reached up to 200 miles per hour, and at ground level the winds were around 175 mph(Stengel 17). With win ....

Bridging Technology And Academ
4303 Words - 16 Pages.... just beginning to consider it, as well as open a dialogue with colleagues regarding its utility as a research tool and a heuristic device in the sociology classroom. Three specific questions guide the discussion: 1) Why should sociologists concern themselves with the Internet?; 2) What are the various Internet technologies available to sociologists?, and; 3) How can faculty begin to integrate these technologies into their classrooms and research.
Key words: teaching sociology, information technology, on-line teaching
Introduction
Information technology is quickly becoming the hub of efforts within the higher education community. Indeed, colleges and universities hav ....

The Geiger-Muller Tube
227 Words - 1 Pages.... or gamma rays pass. Inside the tube is a copper
cylinder with a negative charge. A rigid wire with a positive charge runs down
the center of this cylinder. The voltage across the wire and cylinder is kept
just below the point at which a spontaneous discharge, or spark, occurs. When a
charged particle or gamma ray enters the tube , it ionizes a gas atom between
the copper cylinder and the wire. The positive ion produced is accelerated
toward the copper cylinder by the potential difference. The electron is
accelerated toward the positive wire. As these new particles move toward the
electrodes, they strike other atoms and form even more ion in their path.
Thus a ....

Time To Change
747 Words - 3 Pages.... factory pollutants are only
a couple of the impurities causing damaging affects to the ozone layer and
atmosphere. We depend on the ozone to defend us from harmful UV rays. Finally,
we have a major impact on the degeneration of natural resources. Millions of
gallons of oil, coal, and other valuable resources are wasted each day. These
are just a few of the human disruptions to nature available to our knowledge.
We are conscious of many more, and there are probably others that we are not
aware of. If we do not start taking them seriously soon it will be too late,
if it is not already. We need to reevaluate our priorities and plan for the
future existence of this world. ....

Green Fluorescent Protein Purification
1280 Words - 5 Pages.... a photon, deprotonates to form a phenolate which then emits a photon (at 509 nm) and gets protonated again so the fluorophore returns to its original state. This cycle allows the fluorophore to reliably emit a high yield of light with no outside influence other than the incoming photon. So GFP is basically a stable little (27-30 kD) green light bulb that can be tacked on to other proteins at either the N- or C-terminus without a distortion of its compact beta-can structure. Biochemists now frequently exploit GFP’s unique structural and physical characteristics to visualize various cellular activities.
One such application of GFP is to understand the role of a hormone, ....

Laziness
1951 Words - 8 Pages.... North American Indians, with just half a
percent being affected. Psoriasis seems to affect both males and females
equally. There are two types of the disease. Type I generally occurs
during adolescence, with an average age of onset of sixteen years for
females and twenty-two years for males. Type II affects people over sixty
years of age.
There are several immunological abnormalities associated with
psoriasis. Early psoriatic changes occur in advancing lesions before the
accumulation of inflammatory cells. These changes are mediated by
activated CD4+ T lymphocytes and can be detected before visible pathology
to the skin occurs. Activated T lymphocytes exhibitin ....

Minerals
280 Words - 2 Pages.... and help the blood flow properly.
are classified into 2 major groups. The major elements such as
calcium, magnesium, iron, iodine etc. Then the trace elements such as copper,
manganese fluorine and zinc.
Once of the most important is calcium. Calcium is used to build up your
bones. It also helps to keep your teeth strong. About 90% of all calcium is
stored in your bone's. It also helps with mussel contraction. Milk products such
as milk, cheese and other stuff it the primary source for calcium. You should
have about 1000mg's a day.
Magnesium is also another important mineral. This mineral is in most
foods. It is very important in containing healthy mussel cells. It also ....

The Rain Forest
2207 Words - 9 Pages.... better understand the importance of the rainforest, one must be
knowledgeable about what a rainforest actually is. The two main types of
rainforests are temperate and tropical. Tropical rainforests are located in
Latin and South America, Africa, Southeast Asia, and other areas in which
temperatures stay above 80 degrees Fahrenheit year round. They can be found in
85 countries all over the world, however, 90 percent of them are concentrated
into fifteen countries, each containing over ten million hectares. Tropical
rainforests receive 160 to 400 inches of rain each year. Although these dense,
damp forests cover just 5 percent of the Earth's surface, they can prov ....
