... body. Primary calcium phosphate is an ingredient of plant fertilizer. Phosphates have caused increasing attention recently. The focus is on the environmentally harmful effects in household detergents. Wastewater, from laundering agents, contains phosphates, which are said to be a water pollutant. Most laundry detergents contain approximately 35% to 75% sodium triphosphate (Na5P3O10), which serves two purposes. Providing an alkaline solution (pH 9.0 to 10.5) is necessary for effective cleansing and also to tie up calcium and magnesium ions found in natural waters and prevent them from interfering with the cleansi ...

... Before getting into the specifics of the Debye-Scherrer camera it will be advantageous to beginning with the fundamental concept of simple harmonic motion as it relates to light waves. Simple harmonic motion is the condition in which a particle that is moving along the x-axis has a displacement function given by the following relation x = Acos(wt + f) where x is the position along the x axis A is the amplitude or in other words the maximum possible displacement w is the angular frequency and f is the phase constant or phase angle and has units of radians per second. The phase constant determines the po ...

... years old and that all creatures were made by God in those seven days as they lived exactly today (Campbell p 421). Aside from past resistance, Darwin also comes under scrutiny still today as missing fossils which are to have been the bridge between a two familiar species are not yet found (Hitching p 3). Whatever the reason of belief or disbelief in Darwin's theories, he astounded the scientific world as well as the public and was able to convince many in the presence of a misguided past belief. This fact alone makes him one of the most important people of science ever. Charles Darwin was born in Shrewsbury-Shr ...

... it at a cheap cost. Chapter 2 Mining When uranium is extracted, pitchblende is broken up and mixed with sulfuric and nitric acids. It then dissolves into uranyl sulfate. With the addition of sodium hydroxide, uranium is precipitated as sodium diuranate which is known as the yellow oxide of uranium. To get uranium from carnotite, the ore must be finely ground and treated with a hot solution of caustic and potash to dissolve out the uranium, radium, and vanadium. And after the sandy matrix is washed away, the solution is treated with sulfuric acid and barium chloride. A caustic alkali solution is then added to ...

... about, a mark which will never be forgotten. Although magic is able to deceive the minds of many, few understand its effect of misdirection of the human mind. The first accounts of magic were recorded around 1700 B.C. It appeared on the Westcon Papyrus and was recorded by an Egyptian chronicler. Stories of magic were handed down for centuries (Blackstone, 12). It has made a profitable living for soothsayer and gypsies, but there are times when magic was a form of entertainment. During the seventeenth century magic has become a living for some entertainers. Jugglers, wizards, and fortunetellers often appeared a ...

... large flask, a tray from a scale, a roll of tape, a roll of paper towels, and a spraycan. By dividing the circumference of the circle by the diameter I was able to calculate the experimental ratio, and I knew that the accepted ratio was pi. Then I put both ratios in the chart. By subtracting the accepted ratio from the experimental you find the error. Error is the deviation of the experimental ratio from the accepted ratio. After I had the error I could go on to find the percentage error. The equation I used was, error divided by the accepted ratio times 100. For example, if I took the error of the experimental rat ...

... a difference within yourself or with others. A second advice he gave was to be able to give an example of a failure that you have experienced. Being able to show a life lesson and reflect what you have learned from your failures prove that you are able to overcome obstacles and learn from your own mistakes. Lastly, he said to be able to describe a situation that you have resolved or fixed within a group. This illustrates your ability to be a team player, which is an important skill to possess in every job. All these three qualities can differentiate who you are, and that is the stepping stone of becoming a part ...

... that this issue is too small to deal with right now, and others believe it should be met head on. Power generating plants, industrial commercial, and residential fuel combustion together contribute the rest of the nitric acid. In the atmosphere, the sulfur dioxide and nitrogen oxide transforms into sulfuric acid and nitric acid. Air current can send them thousands of kilometers from the source. When these acids fall to the earth, they will have large impact on the growth and the preservation of certain wildlife. These substance's can neutralize acids entering the body of water, thereby protecting it. However, large a ...

... part... only our solar system revolves around the Earth -- not the universe!) then all of his mathematical formulas would become more "aesthetic". Thus, he composed the theory, which led to great controversial book "On the Revolutions of Heavenly Spheres" in which the church was greatly angered. While Copernicus's book was not a revolutionary book, it was, however, a catalyst to make other minds ponder the new Heliocentric theory. After Copernicus's death there were three other scientists which helped credit the Heliocentric theory. Tycho Brahe was the first, he played with the idea that the pl ...

... of plants and animals that use or live in the coral reef. There are three types of coral reefs: fringing reefs, barrier reefs, and atolls. Fringing reefs are located close to shore, separated from land by only shallow water. Barrier reefs lie farther offshore, separated from land by lagoons more than ten meters deep. Atolls, on the other hand, are formed far offshore and they make a ring-shaped reef that close a circular lagoon. Coral reefs are the largest biological structures on the planet, with the largest being the Great Barrier Reef covering over 2000 kilometers along the East Coast of Australia. The reef is ...
