... manufacture of very many expensive alloys. Cobalt-iron alloys have very unique and special magnetic properties. For example, Hyperco is used as the nucleus in strong electromagnets. Alloys containing titanium, aluminum, cobalt and nickel can be made to become permanently magnetic. One alloy, called Stellite, is an alloy of cobalt, chromium, tungsten, and molybdenum. This alloy is extremely hard and keeps its hardness at extreme temperatures. It has many uses: cutting tools are made of it along with gas turbines. Zaire is the world¹s largest producer of cobalt with 65% of the world¹s reserve. Cobalt is a common trace element found in food. It is a component ...

... tackle general biomedical issues and convey the information to an audience that, for the most part, lack a high level of scientific knowledge. To make the information more understandable for the target audience, authors substitute in less complex vocabulary words, summarize difficult concepts, and often utilize attractive visual aids. Authors strive to communicate issues to audiences of varying levels of education. In order to accomplish this effectively, authors adapt their work in a format that expresses their concepts to audiences in pragmatic fashion. However, a disadvantage is that these adaptations can lead to misinterpretations of information. Attached is a ...

... each other ever since. Today the universe is still expanding, as astronomers have observed. The Steady State model says that the universe does not evolve or change in time. There was no beginning in the past, nor will there be change in the future. This model assumes the perfect cosmological principle. This principle says that the universe is the same everywhere on the large scale, at all times.2 It maintains the same average density of matter forever. There are observational evidences found that can prove the Big Bang model is more reasonable than the Steady State model. First, the redshifts of distant galaxies. Redshift is a Doppler effect whic ...

... prevalence of any disease, women experience only 30-50% of the coronary artery disease incidence and mortality of age-matched men (Meyers, 1996). Many feel that this may be due to the protective effect that estrogen has on the blood vessels of females. There may actually be a direct correlation to reduced serum iron levels due to menses. Whereas men " build-up" iron in the blood, women cleanse themselves of iron buildup on the monthly basis. Meyers (1996) also states that oxidation, the process in which an atom increases its positive charges (Miller and Keane, 1992), of low density lipoprotein cholesterol is important in atherosclerosis, and since oxidat ...

... immunity. The vaccine is given primarily to people who work with livestock or in other businesses where workers must handle animal carcasses. The livestock version of the vaccine is very effective, however. The vaccine for both animals and humans is composed of sublethal amounts of toxin that induce formation of protective antibody. Frequent boosters are necessary to maintain resistance to Anthrax. Bacillus Anthracis spores also may live in soil for years. The only way to destroy the spores is by steam sterilization or burning. There has been no evidence of person to person transmission of the disease, though Anthrax was a subject of great concern for the mil ...

... sheep; using donor DNA and mammary cells from a female sheep cloned it. The process is very technical and I don’t fully understand it myself. From what I have researched I have come to understand that currently cloning is very “Hit or Miss”(Hawley). From 277 attempts, Dolly was the only successful attempt. The point is however that we now have a man created sheep, what else could be done in the near future. There are many different goals for . Would you like to clone someone close to you who had died? In the movie “Gattaca” you get a peak at something that could be made possible by cloning, the genetic engineering of children not yet born. It could be the en ...

... of the past bones were as much as sixteen feet long including the tail. Some even migrated to Texas. There are several species of these animals. The Six-banded Armadillos were good burrowers and massive devourers of insects. They also ate vegetable matter and were useful for devouring carrion. One specie called the Peludo was clumsy bet was effective in getting a snake to its armored hide and grinding the life out of it. It then eats the snake not effected by the poison. The king of the tribe is the Great Armadillo. It is a big creature in appearance, a yard in length from nose to tail covered with the armor. It even has armor on its legs. ...

... it susceptible to a coordinate covalent bond with a hydrogen ion. Also, the carboxylic group is a Lewis acidic because it is able to donate a hydrogen ion (Kotz et al., 1996). Other forms of amino acids also exist. Amino acids may exists as acidic or basic salts. For example, if the glycine reacted with HCl, the resulting amino acid would be glycine hydrochloride (see fig. 2). Glycine hydrochloride is an example of an acidic salt form of the amino acid. Likewise, if NaOH were added, the resulting amino acid would be sodium glycinate (see fig. 3), an example of a basic salt form. Fig. 2 Fig. 3 Due to the nature of amino acids, a titration curve can be empl ...

... limit to their southern range in the middle of Argentina, and their range is expected to be similarly limited to the southern and coastal states in the United States. They have hybridized to some extent with resident wild and hive populations of European honeybees. However, many of the basic African honeybee traits remain, including rapid population growth, frequent swarming, minimal hoarding of honey, the ability to survive on sparse supplies of pollen and nectar, and a highly defensive nature. Africanized honeybees are more difficult to manage than European honeybees and produce less honey. The businesses of many beekeepers in Latin American countries have failed ...

... in muscle cells. Muscular contraction is powered by the breakdown of ATP (adenosine triphosphate) to ADP (adenosinediphosphate). When all the ATP is broken down, creatine phosphate in the muscle donates a phosphate group to ADP, and further energy reactions can occur. Creatine Monohydrate is a precursor to creatine phosphate. By supplementing with CM, CP levels in muscle apparently are maximized, and more muscular work can occur, since there are greater energy reserves to use. Approximately 95% of the body's creatine supply is found in the skeletal muscles. The remaining 5% are scattered throughout the rest of the body, with the highest concentrations in the ...
