... North and South magnetic poles. Along the way, it ionizes (creates an electric charge within) the oxygen and nitrogen gas it encounters in the atmosphere, causing it to glow. The flow of plasma from the sun is generally continuos, although it occasionally bursts out of holes in the sun's outermost atmosphere. Massive ejections of plasma have also been shown to accompany solar flares, prominences, and sunspots. It is during these periods of highest solar activity that one is most likely to witness aurorae. The aurora is an ideal subject for the amateur astronomer because no telescope or any other optical apparatus is needed for observing it. It also makes a good ...
... low pH water that has the ability to mobilize heavy metals contained in geological materials with which it comes in contact. "ARD causes a devastating impact on the quality of the ground or surface water it discharges to. (Ellison & Hutchison)" ACID MINE DRAINAGE Within the mining process there are several sources that cause ARD. No matter what activities occur, ARD usually occurs when certain conditions are met. These conditions are the factors that limit or accelerate the release of ARD. The initial release of ARD can occur anywhere from a few months to many decades after the sulfide containing material is disturbed or deposited. ARD has been associated wit ...
... atmosphere. A manometer is simply a bent piece of tubing, preferably glass with one end closed. When the liquid level in both arms is the same, the pressure of the sample of gas inside the closed end must equal the pressure of the external atmosphere since the downward force on the two columns of liquid is then equal. When the liquid levels are unequal, the pressures must differ. The difference in pressure can be measured in units of length of the vertical column of liquid. The mm Hg, or its modern version the torr, originated in this use of the manometer. Mercury is particularly convenient for use in manometers (and barometers) because at room temperature ...

The use of Meth is going up. In 1995, 3.9% of high school seniors had used it. That's an increase of 2.7% since 1990. 8 out of 10 people who try Meth will become addicted. Famous people who have done Meth include- Chris Farley, John Belushi, and Mick Jagger. The cost of doing Meth is very high too. A user can spend up to $100 a day. And sometime ...
... Thomas DuBose, who took the telephone call from Washington, D.C. ordering the cover-up. Numerous other credible military and civilian witnesses have testified that the original press release was correct and that the Roswell wreckage was of extraterrestrial origin. One such individual was Major Jesse Marcel, the Intelligence Officer of the 509th Bomb Group and one of the first military officers at the scene. On January 12, 1994, United States Congressman Steven Schiff of Albuquerque, New Mexico, announced to the press that he had been stonewalled by the Defense Department when requesting information on the 1947 Roswell event on behalf of constituents and witne ...
... up of a dozen or more tchicks all strung together. Scientific Names The downy woodpecker's scientific name is Picoides pubescens. There are also six particular downies with six particular scientific names all from different regions of the United States and southern Canada which I have listed below: southern downy / Dryobates pubescens Gairdner's woodpecker / Gairdneri pubescens Batchelder's woodpecker / Leucurus pubescens northern downy / Medianus pubescens Nelson's downy / Nelsoni pubescens willow woodpecker / Turati pubescens The downy woodpecker is sometimes reffered to as "little downy." Behavior Towards Humans The downy i ...
... future. Gaining an understanding of a black hole allows for a greater understanding of the concept of spacetime and maybe give us a grasp of both science fiction and science fact. Hopefully, all the clarification will come by the close of this essay. A black hole is probably one of the most misunderstood ideas among people outside of the astronomical and physical communities. Before an understanding of how it is formed can take place, a bit of an introduction to stars is necessary. This will shed light (no pun intended) on the black hole philosophy. A star is an enormous fire ball, fueled by a nuclear reaction at its core which produces massive amounts of heat ...
... until they are 30 or 40 years old. A person with this disease develops uncontrolled movements and may have problems with coordination, thinking, and judgment. A weakening of the nerve cells in the brain causes these symptoms and later results in death. Another single-gene disorder is the Tay Sachs Disease. People who inherit the faulty Tay Sachs gene lack a crucial enzyme that is needed to break down fatty substances in brain and nerve cells. As a result, these substances build up in such large quantities that the central nervous system gradually stops functioning and the person dies. Symptoms usually become evident within the first six month ...
... is why you cannot see them. The particles in a solution are evenly disturbed, or intermingled informally on a molecular level. A small sample of one part of a solution. The particles in a solution will not separate no matter how long the solution is allowed to stand under constant conditions. In a solution, one substance is usually considered to be dissolved, or broken down in another. The substance that is dissolved is called the solute. The substance that does the dissolving is the solvent. Not every substance dissolves in every other substances. A substance that dissolves in another substance is called soluble. Soluble means capable of being dissolv ...
... the group) (Recer). He cloned Dolly using the nucleus from the cell of its mother, and it had an exact genetic replica of its mother. This spurred arguments about cloning humans (Recer). After Wilmut hinted he may be repeating his experiment to silence the critics (Recer). Wilmut does not have the courage to repeat his experiment, also that the government will never allow him to repeate it. Another reason for cloning is that before it was done and even now scientists think cloning could help produce genetic models of human diseases. With this researchers could understand them and develop cures . Also cloning could bring new insights into the process of aging ("Mamm ...
