Is Development Methodologies In Financial
Number of Words: 2415 / Number of Pages: 9
... including telephone banking, credit cards, and auto/property insurance.
The fact that MSFS has entered the Financial Services Sector comparatively recently and with a established IS knowledge base from the parent company has meant that existing information systems have been well developed in terms of technology and are compliant with the latest industry regulations. Therefore there is little or no need for redevelopment of existing systems in the short to medium term, and the ISD focus is almost exclusively on new market areas requiring Information Systems that can be started from scratch. The main ...

Cold Fusion
Number of Words: 695 / Number of Pages: 3
... nucleus. The muon
orbits more tightly around the two captive nuclei leading them to overcome
their natural repulsion of each other and fuse. This reaction produces a
larger nucleus that almost immediately shatters, releasing energy. It also
frees the muon, which can then repeat the cycle, causing several hundred
more such fusions.
The fact that the muon is 207 times heavier than an electron gives
support for this theory. A nuclei is orbited by an electron making a mini-
solar system. If a muon is shot at the nuclei, it will bump the electrons
into a smaller orbit and replace their orbit ...

The Prospect Of Cold Fusion
Number of Words: 1350 / Number of Pages: 5
... together with metals, such as palladium, titanium, and nickel. Usually, some triggering mechanism, such as electricity or even acoustic energy, is required to provoke the "cold fusion" effects. Both ordinary hydrogen and deuterium are abundant in ordinary water so the process would likely end many of the world's energy concerns, if it can be developed commercially.
One of the biggest reasons that cold fusion is so difficult to replicate is that it is not easy to supersaturate a metal with hydrogen or deuterium. The electrolyte, hydrogen or deuterium gas must be kept free of impurities. The metal mus ...

Black Holes

... that astronomers are trying to answer is why isn't the black hole at the center of the galaxy? According to images from the Hubble Space Telescope, the black hole is 20 light-years from the center of the galaxy, but since the black hole is so massive it is hard to explain how it could have been moved. One idea is that the black hole is moving itself. Some astronomers think that the disk of dust serves as a "fuel tank." The black hole sucks in the material which is absorbed by gravity, compressed, and heated to tens of millions of degrees. This theory would explain why radio telescopes have observ ...

Integrated Pest Management
Number of Words: 457 / Number of Pages: 2
... tillage to prevent soil erosion and introduction
of beneficial insects that eat harmful species. Many pests that are attached to
crop residues can be eliminated by plowing them underground. Simple paper or
plastic barriers placed around fruit trees deter insects, which can also be
attracted to light traps and destroyed. Weeds can be controlled by spreading
grass, leaf, or black plastic mulch. Weeds also may be pulled or hoed from the
soil.
Many biological controls are also effective. Such insect pests as the European
corn borer, and the Japanese beetle, have been controlled by introducing their
p ...

Nuclear Power: Worth The Risks?
Number of Words: 2297 / Number of Pages: 9
... and eventually death to those exposed to high levels of radiation. Government declared that nuclear power is safe and efficient. Also have big Oil corporations who have a lot of money invested in nuclear power and want to see as many plants as possible put into and kept in operation. The truth is that accidents do happen at nuclear power plants and at other facilities all the time. An accident at a nuclear power plant has the potential to be much more devastating than an accident at a coal or gas plant because of the radiation that could be released. An example of this is Three Mile Island in Penns ...

The Human Cloning Controversy
Number of Words: 1356 / Number of Pages: 5
... The answer is no. Should scientists be able to make a headless human? (body parts) Yes, as long as no law exists banning headless humans. Before going into this controversy, some background about what has happened in cloning would be useful. Two astonishing feats have been achieved in the scientific world. One is the cloning of a sheep named Dolly, and the other is the development of headless frog embryos. Dolly was cloned in Edinburgh, Scotland, at the Roslin Institute in July 1996. The headless frog embryos were manufactured in London, England, in October 1997 (this didn't get the same amoun ...

Fertilization(IVF - A procedure in which a woman’s eggs are
removed from her body, fertilized outside using sperm from her
husband or another donor, and then transferred back to her body.)
was originally limited to couples that were infertile. Even the
use of IVF for the infertile was unheard of at one point. “But
growing demand makes it socially acceptable, and now anybody
who’s infertile demands IVF,” says Lee Silver, a Princeton
University biologist. Several years ago, fertility clinics
announced t ...

The Autumn And The Fall Of Leaves
Number of Words: 552 / Number of Pages: 3
... a stress upon their sacred
whispers or their prayers. The leaves are hardly heard, but they are heard just
so much that men also, who are destined at the end to grow glorious and to die,
look up and hear them falling.
There is an infinite amount of qualities of describing the leaves. The
color is not a mere glory: it is intricate. If you take up one leaf, then you
can see the sharp edge boundaries which are stained with a deep yellow-gold and
are not defined. Nor do shape and definition ever begin to exhaust the list.
For there are softness and hardness too. Beside boundaries you have hues and
