.... the upper drafts to heights of 50,000 to 60,000 feet. The cumuli become towering thunderheads. From outside the storm area, air moves in over the sea surface to replace the air soaring upwards in the thunderheads. The air begins swirling around the storm center, for the same reason that the air swirls around a tornado center. As this air swirls in over the sea surface, it soaks up more and more water vapour. At the storm center, this new supply of water vapor gets pulled into the thunderhead updrafts, releasing still more energy as the water vapor condenses. This makes the updrafts rise faster, pulling in even larger amounts of air and w .....

.... products they are often emitted into the atmosphere with little or no treatment. The term was first considered to be important about 20 years ago when scientists in Sweden and Norway first believed that acidic rain may be causing great ecological damage to the planet. The problem was that by the time that the scientist found the problem it was already very large. Detecting an acid lake is often quite difficult. A lake does not become acid over night. It happens over a period of many years, some times decades. The changes are usually to gradual for them to be noticed early. At the beginning of the 20th century most rivers/lakes like the river Tovda .....

.... maximum concentration possible without creating precipitation. In this lab, solutions of lead nitrate and potassium iodide will be mixed at a number of dilutions. The reactions will then be observed to see at which point a precipitate no longer occurs. Ksp will then be stated as a range of values at room temperature, and the precipitate test tubes will be heated until the precipitate is dissolved so that Ksp may be observed and determined at different levels. In this experiment various solutions of lead nitrate and potassium iodide were mixed at a number of different dilutions. Through the observation of the amount – or lack of precipit .....

.... from a woman's ovaries and placed in her fallopian tubes along with spermatozoa, thus allowing for normal fertilization. Many times anonomus donors are used. Donors can be matched by factors such as race, color of eyes, hair and other physical characteristics, and are screened for conditions such as AIDS, gonorrhea and other STDS. Even though freezing sperm doesn't seem to affect a pregnancy, it reduces the sperm's movement and influences the success rate of . About 75 to 85 percent of women inseminated with fresh donor semen will get pregnant--especially if the procedure is repeated over several months. Unfortunately, freezing the sperm decreases .....

.... risen by about 15%. Because of the increase of concentrations of these gasses, more energy is trapped within the Earths atmosphere, which is slowly increasing the average heat levels. Scientists predict that the average temperature will rise 1.6 – 6.3°F by the year 2100, which could wreak havoc with climates around the world. Why are greenhouse gas concentrations increasing? Scientists generally believe that the combustion of fossil fuels and other human activities are the primary reason for the increased concentration of carbon dioxide. Energy burned to run cars and trucks, heat homes and businesses, and power factories is responsible for .....

.... commerce is really happening. (34) One of the major reasons that this industry is booming is because purchasing over the Internet has been made very easy compared to the traditional way of shopping. Ordinarily a consumer will take the kids and pile in the family car and head to the local shopping mall. Once they get there they will find what they are looking for only to be told by the rude, pushy sales person that it is out of stock. After they get pushed into something other than what they came for they will wait in a line similar to that of Space Mountain at Disney World. Finally they will head for home after spending about an average of 2.5 hou .....

.... Model. Thus, Layer 3 (network) protocols, such as IP traffic, can be seamlessly delivered over the cable modem platform to end-users. . Since cable modem technology is very recent the conflict exists between different standards. The only specification that has been approved by ITU (in 1998) is DOCSIS (Data Over Cable Service Interface Specifications) which was developed by MCNS, CabeLabs, Arthur D. Little and consortium of North American MCOs. Later that year CableLabs established certification program that would ensure interoperability among the equipment from different vendors. Certified cable modems are expected to appear in second quarter of .....

.... contains the nucleus. * Glial cells interact with neurons and regulate the extracellular environment, protect against pathogens and repair damaged neural tissue. * Axons are-capable of propagating nerve impulses. * Dendrites respond to specific stimuli in the extracellular environment. * Synapse terminals communicate information from the presynaptic cell to the posisynaptic cell. Structural Classification *Anaxonic neurons- have multiple processes and the axon is indistinguishable from the from the dendrites. They're fairly small. *Bipolar neurons- have two processes in which one is a dendrite, and the other an axon. The d .....

.... the youth viewing hours. However, during the prime time viewing hours it’s a different story. The method the television stations use is a mere waste of time and money because a little symbol in the corner of the screen is not going to prevent a child from watching the program. The only way this method can work is if the parents/guardian is there to change the channel but let’s be realistic, how many parents/guardians actuarially have the time to monitor everything there children watch. So most children do end up viewing these programs anyway, and whether we like it or not,the truth of the matter is television educates our children. They educate .....

.... grain to 220 grain, soft, regular (sharp), and hollow pointed shells. With 180 grain bullets, the .30-06 packs about 1300 ft./lbs. of energy at 400 yards. Although, at 400 yards the drop is almost 50 inches; most hunters prefer this one compared to other rifles because of its versatility and accuracy. The expansion is also good, depending on the type of shell tired-used. The kick and distance of the gun are considered to be wonderful because the kick is normal and the distance is better than normal. The .270 rifle is a reasonably good rifle. This rifle is mainly used in open field shooting as opposed to in brush shooting. The depth and the expa .....
