.... were supervised by the Engineering firm of James F. Macharen Limited. Although it is the newest plant, it had it’s disasters. Their intake value exploded twice between 1980 and 1995 because of the extreme pressure and Wight of the water. these incidents cause a shutdown of the plant until they could repair it. Production The Frank J. Horgan Filtration Plant needs only one row materials to operate, which is water. The plant is right next to lake Ontario, collecting water to purify. The water enters the plant by means of two 114 and four 182 million litres per day pumps, .....

.... 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 worry about .....

.... As mentioned above chloroform can be produced which can be used for anesthesia. Also dichloromethane, or paint stripper and 1,2-dichloroethane which is a dry cleaning fluid. Here is a sample reaction where a halogen replaces a hydrogen. CH4(g) + C12(g) ----> CH3Cl(g) + HCl(g) There are many uses for alkanes, for instance: Propane is used in gas grills, butane is used in cigarette lighters, through various reactions scientists can make paint stripper, anesthesia or dry cleaning fluid. The Pentanes and Hexanes are also highly flammable and make really cool explosions. .....

.... observations, Halley concluded that the moon’s rate of revolution around the earth was accelerating overtime. John Harrison was a simple clockmaker and a self-educated person who was accredited for finding by means of a timekeeper. John built his first pendulum watch in 1713. It was constructed entirely out of wood. Harrison called his first sea clock Harrison’s No. 1 or H-1 for short. H-1 was bar-shaped, built out of shinny brass, and was big in size. His second attempt was called H-2. H-2 was a heavy weight of 86 pounds, but fitted into a small box as Joh .....

.... the Bay. This section also experiences two high and two low tides each day (semi - diurnal), with a tidal range varying from 15 to 18 feet, depending on the type of tides. High - water heights vary from 22 to 28 feet and low - water heights vary from 0 to 7 feet above chart data. Because of these semi - diurnal tides and the action of the St John River, slack water in the Habour occurs at approximately tides and not at high or low water as would be the case at other parts. THE RHYTHMIC RISE AND FALL In the Bay of Fundy, the tides are spectacularly large. While the rise and .....

.... tons. When copper is being mined, both Native copper and copper ore are usually found. The highest grade of copper ore is pale silvery gray. Miners used to be always in danger in copper mines. Today, we have reduced a fair amount of these hazards. Miners wear hats made of iron or very hard plastic. This is to protect them from falling rocks. Lamps are also attached to these helmets in case some of the lighting in the mine goes out leaving a miner stranded in the dark. One of the biggest problems with mining is that in some places dangerous gas’s may exist, like Carbon Mon .....

.... seasons. The idealized belt model is a great representation of the general circulation of the atmosphere. The equatorial belt of variable winds and calms ranges from 5 degrees north to 5 degrees south. This wind belt is characterized by weak winds and low pressure from the inter tropical convergence zone. As you go further north or south you encounter the Hadley Cells. Hadley cell circulation is caused by the movement of high pressure from the latitudes at 5 to 30 degrees north and 5 to 30 degrees south to low pressure areas around the equato .....

.... codons, each of which specifies a particular amino acid. (Proteins are composed of amino acids.) A codon consists of a sequence of three bases--for example, GAG or TCA. The four bases can be assembled into 64 possible codons. Because proteins are built from only 20 amino acids, most amino acids are specified by more than one codon. occur when one base is substituted for another or when one or more bases are inserted or deleted from a gene. Substitution affect only one codon, and in most cases the effect is minimal. One reason is the redundancy of the genetic code mentioned .....
