.... of the feedwater heater is 5°C. The rest of the steam is reheated to 500°C, and then enters the second stage of expansion. Part of the steam is extracted between the second and third stages at P2 and fed into an open feedwater heater operating at that pressure. Saturated liquid at P2 leaves the open feedwater heater. The efficiencies of all pumps are 80%, and the efficiencies of all turbines are 85%. Throughout this report the states will be referenced as depicted above with the numbers 1-13. The analysis of the system will involve the use of the Energy Rate Balance to isolate the specific enthalpies and associated values of temperature, pressure, specific volume, a ....

.... growing technical jobs, software engineering tops the list. Carnegie Mellon University reports, "recruitment of its software engineering students is up this year by over 20%." All engineering jobs are paying well; proving that highly skilled labor is what employers want! "There is clear evidence that the supply of workers in the [unskilled labor] categories already exceeds the demand for their services," says L. Mishel, Research Director of Welfare Reform Network. In view of these facts, I wonder if these trends are good or bad for society. "The danger of the information age is that while in the short run it may be cheaper to replace workers with technology, in the lon ....

.... 1997 the first mammal too ever was cloned at the Roslin Institute in Edinburg, Scotland (Staples). It was a sheep by the name of Dolly. Dolly was cloned from an adult sheep; using donor DNA and mammary cells from a female sheep cloned it. The process is very technical and I don’t fully understand it myself. From what I have researched I have come to understand that currently is very “Hit or Miss”(Hawley). From 277 attempts, Dolly was the only successful attempt. The point is however that we now have a man created sheep, what else could be done in the near future. There are many different goals for genetic . Would you like to clone someone close to you who had died? ....

.... 1982) The frog has three lobed livers. The functions of the liver, is to release digestive enzymes to help the stomach and the small intestine with mechanical digestion. The gall bladder stores bile, which breaks down the partially digested foods that, enters the small intestine. Bile has no enzymes but still manages to break down fat into tiny droplets that are ready for faster chemical breakdown. The frog’s stomach is not as complex as a herbivore’s because they have to break down cellulose, which takes a longer time. (Giffard R. & Nat, M 1986) This concludes my study on the digestion system of the frog. FROG'S CIRCULATORY SYSTEM A frog has a closed circu ....

The greatest daily fluctuations occur in deserts near the equator. Temperatures above 100o F (38o C) occur regularly in summer. "Azizia, 25 miles (40 kilometers) southwest of Tripoli, in Libya, holds the record with 136.4o F (58o C), while Death Valley, Calif., comes close with 134o F (56.7o C). "(Genius book of world records 2000) Winters are cold in middle-latitude deserts, located far from the equator.

.... optimistic on what is going to happen, and when it is going to take place. First, to understand what the greenhouse effect is, we must first understand what a Greenhouse is. A Greenhouse is a building made either of clear plastic sheets, or of glass. The sun's rays go through the glass, and heat 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 esc ....

.... upper pool had to possess special adaptations to colonise the area. The lower rock pool generally contained different species which could out compete the organisms of the upper pool when in a more benign environment. The rock pools studied should both contain organisms specially adapted to live in the intertidal environment of the rock pools. The organisms need to be adapted to the microenvironment of the rock pool, as conditions are considerably different to those of a ‘normal’ marine environment. The rock pools spend some of their time completely submerged by the sea and other times exposed to the air. When exposed the organisms of the rock pool are part of a much smal ....

.... known to mankind why doesn't he make the perfect world if he had that much control? There seems to be quite a bit more sustantial evidence on earth to support the theory of evolution. The evidence is holds up more because actual samples of fossils have been collected and scientifically tested using a method called carbon dating to determine the age of the fossils. Which can then be examined and placed along a timeline. The time periods show slight differences in bone structure showing what is hypothesized to be the human evolving. Evolving from what though? The theory of evolution states that creatures change overtime to suit their surroundings. This is called environmenta ....
