Research And Patterns Of Thinking
Number of words: 422 | Number of pages: 2.... It's very difficult to decide what you want to do with the rest of your life in just a short time. I had the plans of working in the woods, so I talked with some friends who work with wildlife conservation and they told me parks and recreation was the way to go. After this strenuous research, I was very glad to get it over with.
Another time I used research was when I restored my car. When I bought the rusty seventy Chevelle convertible, I thought there was no hope for it. I had little experience with restoration of vehicles and figured it would take ages to finish. I decided to write to some places and talk to people to boo .....

Alkanes
Number of words: 362 | Number of pages: 2.... 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.
Heptane, octane and nonane make up gasoline. The "Octane Scale" on gas pumps
uses a system which rates n-heptane at a 0 and isooctane at 100.
Currently propane gas is being studied to use it as a fue .....

The Overpopulation Of The Snow Goose In North America
Number of words: 1801 | Number of pages: 7.... on the numbers and the degradation but may need to do more studies on the impact to other species and look for other options to control the populations.
Population Trends
The numbers of all "light" colored geese has been on the rise since data was first collected. The Lesser Snow Goose (LSGO) has drastically increased in number since data was first taken. Numbers range from around 800,000 in 1969 to as many as 6 million in 1996 (CWS 1999). While the Greater Snow Goose (GSGO) has risen in numbers from a few thousand to almost 500,000 (CWS 1999). This brief article did not provide much insight into actual numbers. Abraham and .....

Tiger Subspecies
Number of words: 562 | Number of pages: 3.... or a tiger subspecies left in the world. That tells
you that there are people that care. But there are so little tigers left that
we can not even keep track of them. We should look at the trend that the
population is taking, rather than the number as a slice in time. Just as you
might say of a young member of the Hunt family, that they were very wealthy. A
hypothetical individual was 24 years old and had $1,000,000. What isn'tavailable
in this one time analysis was that this Hunt inherited $24,000,000 at age 21,
has no education nor ever worked. At age 22 Hunt had $9,000,000 and at 23 had
$4,000,000. Now instead of saying Hunt .....

Nuclear Energy: Uranium Fission
Number of words: 1142 | Number of pages: 5.... water contains 4.6x10^9
tons of uranium. All the world's electricity usage, 650GWe could therefore be
supplied by the uranium in sea water for 7 million years(Energy 25). This is a
only a theoretical number because it is not possible to get all of the uranium
out of our vast oceans. Also, it does not include the fact that in that many
years, half of the uranium will no longer exist due to radioactive decay. So,
at worst, we would get about 2 million years of power from it. Thorium is
another element than can be used in nuclear reactors. Thorium is approximately
four times more abundant than uranium. It is obvious that we are .....

Dolphins 2
Number of words: 3526 | Number of pages: 13.... he jumped overboard and was saved by a dolphin which carried him two hundred miles to shore. Obviously, dolphins and humans have been interacting together throughout recorded history.
According to the theory of evolution, it is most likely that the dolphin was once a land mammal. It is likely that sixty million years ago a cow, the distant cousin of the dolphin, decided to take his life to the sea. This is shown by the findings of hooves on dolphin fossils.
The appearance of dolphins has intrigued man’s interest in the physical makeup of these mammals. Dolphins are carried by their mothers for twelve months before they are bor .....

Newton's Laws Of Motion
Number of words: 484 | Number of pages: 2.... or roll on one another.
Any change in an object’s speed is called acceleration. An increase in speed is called positive acceleration, while a decrease in speed is called negative acceleration, or deceleration. Acceleration can also mean a change in direction as well as in speed. A force is needed to change the direction of an object, so a change in force can also mean a change in direction as well as a change in speed. According to Newton’s Second Law of Motion, the change in direction of a moving object depends on the applied force.
The amount of acceleration depends on the object’s weight. A lighter object will acce .....

Experimental Protein
Number of words: 3276 | Number of pages: 12.... with huge molecular weight did not travel far from the gel while low molecular weight proteins traveled long distance . Overall banding contrast was compared between same sample with different transferred volumes. The protein bands of ADH were closely related to some of the bands of liver protein extract. ADH, which is derived from horse contains some of the protein that are related to the proteins found on cow's liver cells. Closely ranged Rf value is key to similarities that exists between protein bands based on their molecular weight. The results of these experiments were compared with research group with similar in .....

Insomnia
Number of words: 1101 | Number of pages: 5.... to pin down the exact cause of sleep problems. Of 1,000 households, one third had someone with current problems and in 42 percent someone had suffered from sleep disorders at sometime. Some doctor's polls have been revealing yet somewhat disparate. In one survey, roughly 19 percent of the patients seen by the 3,000 doctors had complaints of some type of . That figure may actually understate the case, for some say that more people in the United States visit doctors for help in getting to sleep than any other single complaint. It is also estimated that half of those not considered cs have a sleepless night on occasion, and a .....

Big Bang
Number of words: 1243 | Number of pages: 5.... This principle says that the universe is the same everywhere on the large scale, at all times.2 It maintains the same average density of matter forever. There are observational evidences found that can prove the model is more reasonable than the Steady State model. First, the redshifts of distant galaxies. Redshift is a Doppler effect which states that if a galaxy is moving away, the spectral line of that galaxy observed will have a shift to the red end. The faster the galaxy moves, the more shift it has. If the galaxy is moving closer, the spectral line will show a blue shift. If the galaxy is not moving, there is no shi .....
