.... structure Decker predicted did not mean that his nomenclature would be used to identify the compound. That honor was bestowed upon its discoverers Landa and Machcahcaeck who used the Greek translation of diamond, , to identify the compound.2 Crude petroleum is separated into its component compounds by fractional distillation. The procedure involves a sample of the petroleum to be heated until the sample is vaporized leaving behind any solid impurities. The resulting steam enters a fractional distillation column in which a temperature gradient had been instilled. The tempera .....

.... first to arrive and spread slowly but steadily despite government intervention to stop them from spreading(3. Lockley 33). These black ants would spread much further then the second wave of imported ants recognized as Solenopsis Invicta Buren or red fire ants(4. Lockley 33). This second wave of ants arrived in about 1945 and spread much more rapidly and dominated the previous more passive black ant(5. Lockley 34). Homer Collins, a fire ant expert, stated that "The new invader, known as the red imported fire ant, proved more adaptive and rapidly displaced the existing i .....

.... gelatin. Administered orally. Microemulsion: Microemulsions are thermodynamically stable, optically transparent, isotropic mixtures of a biphasic oil-water system stabilized with surfactants. The diameter of droplets in a microemulsion may be in the range of 100 A to 1000 A. Microemulsion may be formed spontaneously by agitating the oil and water phases with carefully selected surfactants. The type of emulsion produced depends upon the properties of the oil and surfactants utilized. Ointment: Semisolid preparations intended for topical application. Most ointments ar .....

.... traits, that are passed from parent to offspring. By chance, some varieties prove to be ill adapted to their current environment and thus disappear, whereas others prove to be adaptive, and their numbers increase. The elimination of the unfit, or the "survival of the fittest," is known as Natural Selection because it is nature that discards or favors a particular being. Evolution takes place only when natural selection operates on apopulation of organisms containing diverse inheritable forms. HISTORY Pierre Louis Moreau de Maupertuis (1698-1759) was the f .....

.... up the air inside the building, and they have a hard time getting out. These rays get trapped inside the building, and continually heat the air inside, and even through the night the rays stay in and heat the air. The greenhouse is also called a "HOT HOUSE" because it gets so hot. The greenhouse effect is caused by gases such as carbon monoxide, carbon dioxide, and nitrogen escaping into the atmosphere. These gases get trapped in the ozone layer and do not let the suns rays escape very easily. This causes the earth to warm up. This warming can cause droughts, and this wou .....

.... numbers of object that could serve as a comfort. Take public transportation for example. The thought of having the train that takes us into the city is a commonly know option. Not always have people been able to choose public transportation as a method of getting to and from. Dating as far back as 1889 when the first method of public transportation was developed in Massachusetts. Before this the thought of having a bus or train run to the main areas of a community was absolutely unheard of. But in today’s society there are many people who depend of the train or bus .....

.... gigantic, gas clouds bind together due to attractive forces and form a hot core, combined from all the energy of the two gas clouds. This energy produced is so great when it first collides, that a nuclear reaction occurs and the gases within the star start to burn continuously. The Hydrogen gas is usually the first type of gas consumed in a star and then other gas elements such as Carbon, Oxygen, and Helium are consumed. This chain reaction fuels the star for millions or billions of years depending upon the amount of gases there are. The star manages to avoid collap .....

.... C-clamps, inertial scale, a watch with a second hand, and a triple beam balance. Procedure: 1) The class will measure the period of oscillation of their balance pans when they are empty. The accepted period will be the average of the class. To find the period, you will measure the amount of time it takes for your balance to complete 20 oscillations. The period (T) will be computed by taking your time and dividing it by 20. This will be recorded as T2. 2) You will then measure the mass of your empty pan (including all screws) and record this as m2. 3) You will then .....
