Gold And Its Uses.
.... into small chunks and placed on carefully lined pads where a dilute cyanide solution is distributed over the surface of the heap. The solution percolates through the heap and the cyanide dissolves the gold. This solution containing dissolved gold is then collected. Refractory ore containing carbon is roasted to over 1,000 degrees Fahrenheit, burning off the sulfide and carbon. The product of this process is an oxide ore, which is routed to the leaching circuit. Oxide ore is sent directly to the leachi .....

Gonorrhea
.... long-term consequences of gonorrhea. Serious complications can result, however, when left untreated. Long term complications in men may include Epididymitis. Long term complications in women include Pelvic Inflammatory Disease, ectopic pregnancy, perihepatitis, sterility Gonorrhea can be transmitted to newborns. Approximately 2% of persons with untreated gonorrhea may develop Disseminated Gonococcal Infection (DGI). This develops into a fever, skin lesions and arthritis type pain.
Gonorrhea is tr .....

Gps

The GPS is an all purpose system, meaning that it can be used for other things than cars, in fact, it wasn't even made originally fo .....

Gravity
.... pennies, acorns, and crumpled balls of paper.
There is another legend that states that when Newton was lying against a tree in an orchard, he was struck on the head by an apple. He wondered what provided the acceleration for the apple to fall to the ground. Was this a force of the earth on the apple? If so, then the apple must exert a force on the earth according to Newton’s law of action/reaction forces.
Newton applied this theory unto the planets, which orbit the sun. He found by studyi .....

Great White Sharks
.... and in the fall, they turn south and move along the
offshore islands. They are also found in great numbers in the Australian waters.
The great white is a very agile killer that hunts mostly anything in the ocean. They
are carnivorous and usually prey on sick or injured prey. Just one drop of blood can make
the shark go into a feeding frenzy. It is not made to swim fast and its usual speed is
fifteen miles per hour. It migrates south to warmer waters to give birth to .....

Greenhouse Effects Speech
.... 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 about 80% of society's carbon dioxide em .....

Greenhouse Gases And Consequences
.... (CFCs), Ozone (O3), and Nitrous Oxide (N2O).
It all seems very straightforward: greenhouse gases trap the sun's heat, warming the planet sufficiently for life to exist. There is, however, one problem: human activity has dramatically increased the amount of greenhouse gases in the atmosphere.
Over the last two centuries the concentration of greenhouse gases in the atmosphere has increased quite significantly, mainly as a result of burning fossil fuels for industrial purposes. For example, atmo .....

Ground Water In Ontario
.... urban centres which rely predominantly on surface sources for their water, most of Ontario relies on groundwater supplies. Although these groundwater supplies are abundant, not all are usable. In some cases the water has been polluted - as is the case in Elmira - and in others it is simply unpalatable because of high sulfur and other mineral contents. But because of the amount of groundwater which is actually used throughout Ontario, it is quite shocking that a majority of people are unaware of the inhe .....

Growth Rate Of A Seed
....
Results and conclusion: My hypothesis was correct. As you can see from the data graphs at first the seeds germinated at the same rate until the tip of the radicle broke trough and was visible. Afterwards the seed which was in the light grew more rapidly then the seed which was in the dark. I think this happened because when the seed is in the early stages of germination it does not use light to grow but is controlled by phytochrome. Which is a hormone that controls the germination of a seed before it re .....

Gulf War Syndrome

To identify symptoms which may define the syndrome, Robert W. Haley, M.D., from The University of Texas Southwestern Medical Center at Dallas, and colleagues have conducted a series of investigations that broke the Gulf War Syndrome into three different types. To support their investigation, twenty five percent of 249 veterans who served in the Desert Conflict reported clusters of symptoms th .....

H.i.v. About Aids
.... of viruses in general, and how HIV infects the body.
Definition
HIV is the virus that causes AIDS. HIV is classified as a RNA Retrovirus.
A retrovirus uses RNA templates to produce DNA. For example, within the
core of HIV is a double molecule of ribonucleic acid, RNA. When the virus
invades a cell, this genetic material is replicated in the form of DNA .
But, in order to do so, HIV must first be able to produce a particular
enzyme that can construct a DNA molecule usi .....

Handling Stress
.... Now that we have an idea on what stress is the next question we should ask ourselves is ³what is or can cause stress². CAUSES OF STRESS There are many different things that cause stress. One may be if you have a big term paper due and you want to do your best to impress your seminar leader. Another may be peer or family related. All in all it is things, events, situations, and people that cause stress. It is how we perceive them that will determine whether or not stress will be a result from the enc .....

Hanta Pulmonary Syndrome
.... longer, making the chances of contracting it somewhat higher. In places such as woodpiles and sheds where there is little air circulation to move off the virus, it can linger for a sizeable duration of time.
The best method of fighting the hanta virus is prevention. By controlling the rodent population and preventing them from entering houses and sheds, the risk of infection can be lowered. Furthermore, educating those in high-risk areas of the signs of the disease and what to do about them signifi .....

Hantavirus
.... were worried that since the virus was so prevalent in Korea that it possibly could be spread easily from boat to new land through trade. When rats were tested in various harbors throughout the United States, the Seoul virus, a form of hantavirus, was found. In 1982, a study in Baltimore tested local rats and found that every rat over the age of two had the virus in their system (Garrett 539). Then individuals from two STD clinical-hospitals were tested and four cases of the Korean Hantavirus were foun .....

Hard Drive Evolution
.... 3.5-inch floppies is similarly constructed, but they are housed in a rigid plastic case, which is much more durable than the flexible covering on the larger diskettes.
With the introduction of the IBM PC/XT in 1983, hard disk drives also became a standard component of most personal computers. The descriptor "hard" is used because the inner disks that hold data in a hard drive are made of an aluminum alloy. These disks, called platters, are coated with a much-improved magnetic material and last .....
