... and what happens to a star when fusion can no longer occur. The first question one must ask is, "What is fusion?" One simple way of explaining it is taking two balls of clay and mashing them into one, creating a new, larger particle from the two. Now replace those balls of clay with sub-atomic particles, and when they meld, release an enormous amount of energy. This is fusion. There is currently three known variations of fusion: the proton-proton reaction (Figure 1.1), the carbon cycle (Figure 1.2), and the triple-alpha process (Figure 1.3). In the proton-proton reaction, a proton (the positively charged nucleus of a hydrogen atom) is forced so close to an ...

Lastly the importance of high fibre foods in conjunction with a healthy lifestyle is presented as the 'formula' for a healthy body and avoidance of fibre depleted foods, a fact which is sadly abundant nowadays, is also mentioned. Since ancient times, foods containing complex carbohydrates have been considered to be the ones with most nutritional value. Even the Bible speaks of how the complex carbohydrate manna miraculously sust ...

... of Arizona in Tucson. "This is just our first tentative glimpse into the very remote universe," says Alan Dressler of the Carnegie Observatories in Pasadena, CA. "What we see may be the first stages of galaxy formation. But the objects are so faint that their true nature can only be explored with the advanced telescopes of the future." "This observation is a major step toward fulfilling one of Hubble's key objectives: to search for the faintest and farthest objects in the universe," adds Ed Weiler, NASA's acting Associate Administrator for Space Science. In a separate discovery, Thompson also found that faint red galaxies matched up with compact blue knots of ...

... predation between wolves and large ungulates involves carnivores preying on herbivores. Predation can have many possible effects on the interrelations of populations. To draw any correlations between the effects of these predator-prey interactions requires studies of a long duration, and statistical analysis of large data sets representative of the populations as a whole. Predation could limit the prey distribution and decrease abundance. Such limitation may be desirable in the case of pest species, or undesirable to some individuals as with game animals or endangered species. Predation may also act as a major selective force. The effects of predator prey coevolut ...

Patients that have experienced the treatment claim that "is less painful than getting a shot or having blood drawn because the needles are so thin" (Weiss 73). The question remaining involves the legitimacy of treatments. It has a long history of success in Asia dating back over 5,000 years (Duke 224). The method approaches problems as "patterns of disharmony" which are responsible for poor health in individuals (Consumer 55). Oriental acupuncturists believe that either yin or yang, whose balance affects everything in the universe, influences each of the body's organs. They als ...

... sea-surface temperatures in the eastern tropical Pacific rise above normal. In normal, non-El Nino conditions, the trade winds blow towards the west across the tropical Pacific. These winds pile up warm water in the west Pacific, so that the sea surface is about 1/2 meter higher at Indonesia than at Ecuador. The sea surface temperature is about 8 degrees C higher in the west, with cool termperatures off South America, dut to an upwelling of cold water from deeper levels. This cold water is nutrient-rich, supporting high levels of primary productivity, diverse marine ecosystems, and major fisheries. Rainfall is found in rising air over the warmest water, and t ...

... that we recognize all we do as humans to ensure our plentiful and gluttonous lifestyles. Lets face it. We as humans waste countless hours of our lives worrying about the future. Whether it’s asteroids or Y2K, it’s always something. It is said that in the future, with global warming, temperatures outdoors will be too hot to survive in. But what is the future? Is the future tomorrow, maybe next month, or next century? The fact is by the time all of the problems that we worry about surface, we will have been dead for hundreds of years. We’ll be safe somewhere in the afterlife with our children and their children. We don’t have to wo ...

... mg of potassium, 2000 mg of sodium, 65 g of protein, 1.5 mg of thiamin, 1.7 mg of riboflavin, 20 mg of niacin, and 18 mg of iron. Nutritionists of today simplify this into an equation of 40% carbohydrates, 30% fats, and 30% protein that the entire day’s meals should be divided into. The total calorie intake must increase for active persons from 2200 to 2200 plus the total number used while exercising. This will ensure replenishment of the body’s system. With the wide variety of athletic competitions, the specific meal a competitor may need to eat to benefit themselves differs widely, as do the events. The last meal or two are extremely important in ...

... for targeted research to try to explain these occurrences. "It may be valuable to carefully evaluate UFO reports to extract information about unusual phenomena currently unknown to science," the report stated, adding that such research could also improve understanding of, and in some cases debunk, supposed UFO events. For example, Earth science researchers have eventually accepted several phenomena "originally dismissed as folk tales," including meteorites and certain types of lightning, the panel noted. The findings are from a four-day workshop held in Tarrytown, N.Y., followed by a second three-day meeting in San Francisco, both last fall. The results are ...

... dissolve in each other in any proportion; others have limits. If a solute added to a solution above a certain amount will not dissolve, the solution is called saturated. For most substances, solubility increases with increasing temperature of the solvent. In general, molecules that are structurally similar to the molecules of the solvent have the highest solubility. When a solute is added to a solvent, several physical properties of the solvent change. Its boiling point rises and its freezing point lowers with increasing concentrations of solute. Solutions are similar to other types of mixtures known as colloids and suspensions. Colloids are mixtures of tiny ...
