Nuclear Energy

... the country. Even though atomic power has been in use for over 50 years it was basically another weapon of destruction. Since there was no war, the scientists who created the atomic bomb, turned this destructive power into huge plants generating "clean and cheap "electricity for the country. But this new resource brought sickness, mutations, cancer and eventually death to those exposed to high levels of radiation. Even the government declared that nuclear powers were safe and efficient. The truth is that accidents do happen at n ...

Genetic Cloning ----

... in hopes of preventing rejection after transplantation. Pigs have organs that are about the right size and are similiar to humans, also the availability of these organs is great due to the reproductive cycle of pigs. The biggest obstacle is the issue of rejection. The new organ is typically killed, even before the surgeon closes the incision, due to hyperacute rejection. This process clots the blood, by forming antibodies that attach to the endothelium of the blood vessels in the organ. The complement system creates gaps in vessels, allow ...

Smuggling Of Nuclear Material

... enriched uranium (HEU), and 165 tons of weapon usable plutonium. Such material is coming into high demand on the market. Terrorist, organized crime and countries with nuclear ambition, are high bid contenders for the material. The United States is also becoming involved for the safety of preventing a nuclear disaster. The U.S. has just begun their large task and with Russia's worsening economy, smuggling of nuclear material will continue. During the Cold War the security of Soviet nuclear weapons and missile materials was based on a highl ...

The Application Of Science To Engineering

... induction discovered by an englishman, Micheal Faraday, in 1831. This discovery was applied to mechanical generation of electricity which made tremendous improvements to communications throughout Canada. The electric telegraph, first discovered in 1837 by Samuel Morse, was a great improvement over the mechanical telegraph which required the use of a telescope and was much less effective. It encodes messages electrically, transmits them over facilities such as copper wire, coaxial cable, and fibre optics to their destination where they are ...

Acid Rain And Its Effects

... the acidity of rain by measuring the pH value. As the acidity in rain increases, the pH level decreases. Therefore, acid rain has a lower pH value, than normal rain Acid rain is a serious, and damaging national problem. I don’t think people are fully aware of the serious consequences that acid rain have on many different factors. For one, Acid rain causes acidification of lakes, streams, and other bodies of water. Because many lakes and streams suffer from chronic acidity (a condition which water has a constant low pH level) this ma ...

Photosysthesis Experiment

... a balancing of energy is occurring more energy is produced. These are the two ways that energy is created during light reactions. Dark reactions can occur in the absence of light as well as when light is present. The first and most important step of dark reactions, the carbon fixation step, involves rubisco. What happens is that rybluose which contains five carbons takes the carbon in carbon dioxide and makes the six carbon sugar glucose as described in Vodopich's definition. For the first part of our experiment we wanted to observe how ...

Organ Cloning: The Future Of Our Lives…

... the lives of people. Many people say that we should not try to interfere with nature. If we try to clone organs for transplant patients that are in their final hour then we are actually improving their life. If you feel that saving a person’s life is a bad thing, then I’m sorry. People often question whether or not we have the right to clone. We are all guaranteed rights by the fact that we are human beings. Those rights include the right to pursue areas of scientific study, and also the right to live. They could have argued the fact tha ...

Genetic Engineering Of Foods

... strands of DNA. Using such enzymes, scientists learned to cut specific genes from DNA and to build customized DNA using these genes. They also learned about vectors, strands of DNA like viruses, which can infect a cell and insert themselves into its DNA. With this knowledge, scientists started to build vectors which incorporated genes of their choosing and used the new vectors to insert these genes into the DNA of living organisms. Genetic engineers believe they can improve the foods we eat by doing this. For example, tomatoes are sensitiv ...

Nasa

... 1999, where it will serve as a weather satellite for a full martian year (two full Earth years). The next Mars lander is scheduled for January 3, 1999 liftoff. Mars Polar will touch down on Mars in December 1999, carrying two softball-size penetrators, the Deep Space 2 mission, that will crash land on Mars some 60 miles north of the landing site. All is going well with ’s Saturn-bound Cassini mission and the Deep Space 1 mission. Cassini will reach Saturn in June 2004 and Deep Space 1 will rendezvous with asteroid 1992KD in July 1 ...

Copper And Aluminium

... Bronze. Bronze can be easily cast in large shapes, so is used for making statues. It also has a unique sound when struck, which makes it ideal for making bells. Bronze resists corrosion, but weathers to a beautiful brown or green colour. Copper is also used for locks, pipes, plumbing fixtures, door knobs, drawer handles, lamps, pots, pans roofing, and jewellery. Certain chemical compounds of copper can be used to help improve soil, and destroy harmful insects. Copper can also be used to help protect other materials against corrosion, and in ...

Dsl Should Be The Standard For Telephone Lines

... time. With DSL, two people could talk on the phone to different people, or someone could be on the internet and talk on the phone at the same time, all with one phone line. Another advantage of greater bandwidth is faster internet connections. On a normal analog phone line, the fastest internet connection available is 56 kb/s (kilobits per second). With DSL, the normal speed is 384 kb/s with the max at 1.1 Mb/s (megabits per second). With DSL, one's computer could be online at all times. There would be no busy signals or dial-in hassles. ...
