Internet 2

... use of credit card information related to on-line financial transactions, General site and security and Information security. Some companies claimed that they offer their customers a secure gateway that cannot be access by hackers. The purpose of this paper is to discuss the issue of secure payment. In so doing, I will explore how secure is secure. Commerce on the internet consists mainly of passing credit card numbers and expiry date information electronically between the merchant and the customers. When commerce is conducted ...

Effects Of Drugs On Pregnet Women

... reductions in oxygen delivery. As well nicotine interferes with the ability of the placenta to feed the baby the nutrients it requires. Therefore the babies growth is slowed down. Carbon monoxide causes growing cells to be starved of oxygen, and effects the brain. This can lead to a low birth weight and higher chance of the baby dying at birth. Smoking is the single largest modifiable( changeable) risk factor in fetal growth retardation. Maternal smoking during pregnancy is also associated with genetic defects as well as an increased in ...

Water And Its Importance

... makes it especially unique, giving its properties special characteristics. Waters cohesion and adhesion properties allow it to be transported in plants, and its surface tension provides a comfortable habitat for many insects. Water is also one of the best solvents. The specific heat property of water stabilizes temperature in living organisms and its high heat of vaporization regulates earth's climate. One of the most unique things about water is the fact that it expands when it freezes unlike many other liquids. Its thermal and transpar ...

Catscan

... takes shorter time and the sample is not affected or destroyed during the procedure- the advantages are numerous. This technique enables us to visualize the inside of us humans, organisms or other objects in 3-D geometry. CTscans stands for “Computed Tomography”. It is a way of looking inside your body using a special camera. It is an advanced scanning x-ray and computer system that makes detailed pictures of horizontal cross-sections of the body, or the part of the body that is x-rayed. A CT scan is a diagnostic test that combines the u ...

Wired Hands - A Brief Look At Robotics

... or baby brontosauruses with their fat, squat bodies, long arched necks and small heads. An industrial robot is essentially a long manipulator arm that holds tools such as welding guns or motorized screwdrivers or grippers for picking up objects. The robots working at Chrysler and in numerous other modern factories are extremely adept at performing highly specialized tasks - one robot may spray paint car parts while another does spots welds while another pours radioactive chemicals. Robots are ideal workers: they never get bored and they ...

Human Cloning

... impossible to avoid, but the overall idea of cloning humans is one that we should accept as a possible reality for the future. The initial public response to this news, here and abroad, was primarily one of concern. In some cases, these concerns were amplified by largely fictional and mistaken accounts of how this new technology might dramatically reshape the future of our society. The sources of these feelings were complex, but usually centered around the basic fact that this technique would permit human procreation in an asexual m ...

Copper Report

... is unknown. Cu is Copper's chemical symbol. It contains 29 protons/electrons (atomic number) and 35 neutrons. It's atomic weight is 65.39. Copper is an orangy, red metal that is found in ores as a solid form. It can be found in such countries as the United States, Chile, Zambia, Zaire, Peru, and Canada. The most important copper ores are the sulfides, oxides, and carbonates. From these copper is obtained by smelting, leaching, and electrolysis. It's alloys, brass and bronze, long used, are still very important; all American coins a ...

Carbohydrates

... be as small as 3 or as large as 8. They are characterized by hydroxyl groups and an aldehyde or ketone group. These functional groups make sugars highly soluble in aqueous solution. In solution the aldehyde or ketone group has a tendency to react with one of the hydroxyl groups, producing a ring structure. The alpha glucose, which is the base of many polymers, is an energy source in organisms. Although glucose is the common transport sugar for vertebrates, sugars are often transported in other organisms as disaccharides. Sucrose, commonly c ...

Observed Distribution Of South American Relief Features

... see it today. The positions of the landmasses today are a result of continental drift. During the Earth’s existence, the magnetic fields have never been stable. Solidified magma containing magnetic imprints reveal periods of time when the Earth’s magnetic fields have actually been reversed. Convection is caused by non-uniform temperature in a fluid and density differences. This continuous convection is the cause of plate movement. Each complete cycle, called a convection cell, drives the plate in the direction of the cell. How does a ‘ ...

Computer Graphics

... now sitting in front of computer screens. There, they edit entire features while adding sound that is not only stored digitally, but also has been created and manipulated with computers. Viewers are witnessing the results of all this in the form of stories and experiences that they never dreamed of before. Perhaps the most surprising aspect of all this, however, is that the entire digital effects and animation industry is still in its infancy. The future looks bright. How It Was In the beginning, computer graphics were as cumbersome ...

Global Warming

... 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 has been in the past million years. Average global temperat ...

Properties Of Water

... together and give it its cohesiveness. These bonds are also very important to water's ability to absorb heat, as without hydrogen bonds water would have a boiling point of -80 degrees C and a freezing point of -100 degrees C. In reality, however, water has a boiling point of 100 degrees C and a freezing point of 0 degrees C. The amount of energy needed to raise the temperature of one gram of water by one Celsius degree is called a Calorie. One Calorie is about twice as much energy as you need to warm one gram of most other fluids by the sa ...
