Nuclear Energy

... Do we get any other benefits from nuclear power plants? You bet. They provide an alternative to burning vast amounts of fossil fuels—making electricity production much easier on the environment. They produce much of the electricity that fuels our economic growth. They power new industrial technologies that keep our economy growing and improve our global competitiveness. They cut America's demand for imported oil by nearly 100 million barrels a year—reducing our dependence on foreign oil suppliers and cutting ou ...

Nuclear Power: Cons

... power, new studies concerning the health of nuclear by-products and scares of nuclear accidents like those at Chernobyl are slowly rendering Nuclear Fission an obselete energy source. This essay will prove that nuclear power is a dangerous technology and with many other sources and the dangers involved, the disadvantages of nuclear power far outweigh the benefits. Alternative sources of energy are making their way into the highly competitive field of electricity production. With the wealth of sources such as solar, wind, hydro or geothermal ...

Fusion 2

... kinetic energy to undergo fusion. Such a medium can be produced by heating an ordinary gas of neutral atoms beyond the temperature at which electrons are knocked out of the atoms. The result is an ionized gas consisting of free negative electrons and positive nuclei. This gas constitutes a plasma. Plasma, in physics, is an electrically conducting medium in which there are roughly equal numbers of positively and negatively charged particles, produced when the atoms in a gas become ionized. It is sometimes referred to as the fourth state ...

DNA

... organism, most DNA is found within a single chromosome like bacteria, or in several chromosomes like most other living things. (Heath, 110) DNA can also be found outside of chromosomes. It can be found in cell organelles such as plasmids in bacteria, also in chloroplasts in plants, and mitochondria in plants and animals. All DNA molecules contain a set of linked units called nucleotides. Each nucleotide is composed of three things. The first is a sugar called deoxyribose. Attached to one end of the sugar is a phosphate group, and at the othe ...

Vivisection

... who are going to die anyway. With all of the technology we have today we should be able to make a human replica. What is the use of inmates on death row? They are just going to die anyway. They should have a choice to do something good first for man kind. I think a several people would volunteer because if scientists find a cure for something the inmate would be known as a hero. I do not think they should make them do it because they have rights too. Inmates should be able to do it if they want. The inmates should be asked that questio ...

Freedom Of Bytes

... anything and everything possibly conceivable by humans. Through the computer people are now literally a few mouse clicks away from buying anything from cars to toothbrushes, clicks away from entering a chatroom and conversing with fellow “Netizens”, and few clicks away from databases, essays, articles, and multimedia presentations on any entity whatsoever. For the same reasons that the World Wide Web is so valuable and popular, it is also bad and dangerous. You might be able to shop around for an airplane ticket and might dec ...

Cable Vs. V.90 Modems

... T1 lines which puts an absolute limits on speed of cable connection to 1.5 Mbps The cable modem access network operates at Layer 1 (physical) and Layer 2 (media access control/logical link control) of the Open System Interconnect (OSI) Reference Model. Thus, Layer 3 (network) protocols, such as IP traffic, can be seamlessly delivered over the cable modem platform to end-users. . Since cable modem technology is very recent the conflict exists between different standards. The only specification that has been approved by ITU (in 1998) is DOC ...

Effects Of Deforestation

... is harmful to the environment and leads to declining wildlife populations, drastic changes in climate and loss of soil. The loss of forests means the loss of habitats for many species. Current statistics show that as many as 100 species become extinct every day with a large portion being attributed to deforestation (Delfgaauw, 1996). "Edge effects" are the destruction or degradation of natural habitat that occur on the fringes of fragmented forests. The effects for the animals include greater exposure to the elements (wind, rain et ...

DNA

... body need to make proteins is coded and contained in the order of these bases along the length of the DNA ladder. All DNA molecules consist of a linked series of units called nucleotides. Each DNA nucleotide is composed of three subunits: a special sugar called deoxyribose, a phosphate group that is joined to one end of the sugar molecule, and one of several different nitrogenous bases linked to the opposite end of the deoxyribose. DNA has two specific functions: to provide foe protein synthesis, and hence the growth and development of the ...
