... positive and negative by Benjamin Franklin. Another idea was that electric samples of the same kind repel each other, and those of different kinds attract each other. This later was named the law of electrical charges, and is essential to the understanding of electricity. A third idea was that if the distance between electric charges is increased, the force of attraction or repulsion decreases. All matter is made up of very tiny particles called atoms. Atoms are made up of even smaller substances called subatomic particles. Scientific studies have found that some of these subatomic particles are charged with electricity. The electric charges are made up of t ...

It is that little addicted voice inside their minds rationalizing the addiction, because they know, it might hurt to quit. They know that there will be a sense of loss.

Medical examiners are usually physicians specializing in forensic pathology, the study of structural and functio ...

... suffer from depression only during autumn and winter, when there are fewer hours of daylight. In dysthymia (pronounced dis-THI-mee-uh), people feel depressed, have low self-esteem, and concentrate poorly most of the time—often for a period of years—but their symptoms are milder than in major depression. Some people with dysthymia experience occasional episodes of major depression. Mental health professionals use the term clinical depression to refer to any of the above forms of depression. Surveys indicate that people commonly view depression as a sign of personal weakness, but psychiatrists and psychologists view it as a real illness. In the United States, the ...

... appropriate at the time. The name was changed to Frank J. Horgan Filtration Plant at 1990 by the commissioner of works for Metro Toronto. This plant cost about 57 million dollars to construct. About nineteen major contractors worked on this plant and 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 ...

... structure to the cell. Then there is the Nucleus, which serves as a control center for the cell. Inside the Nucleus there are one or more Nucleoli. They are dense, granular bodies that disappear at the beginning of cell division and reappear at the end. Then you have the Cytoplasm. This is the watery material lying within the cell between the cell membrane and the nucleus. The Cytoplasm also contains organelles, which have specific functions in the cell metabolism. Then there are the Golgi Bodies, which serve as processing, packaging, and storage for the cell. These organelles package and ship things out. Another parts of the cell, a very important one in fact, ar ...

... the late twentieth century as a time of health and tranquility. As we show you, in the world of viruses, we are the invaders (Baddorf, Ourworld.compuserve.com)." Between the years of 425BC-430BC Athens' population was dramatically reduced when about 300,00 of its inhabitants died from some sickness. Some people now believe that this great plague was really Ebola. The first recorded outbreak of the Zaire string of the Ebola virus was in Zaire, in 1976. The doctors didn't know how to treat it and that meant that they didn't know how to contain it either. As infected people met in public places the virus spread. In Western Sudan, the same year, the Sudan st ...

... (Gorrie 71). And while Canadians are for the most part are unaware of how much water they consume, they are even less aware of its presence around them. For water is an immense natural resource that rests not only around Canadians, but beneath their feet as well. In no region is this more pervasive than in the province of Ontario. Ontarians walk above groundwater supplies everyday, without the slightest notion of the extent to which they rely on this over-used and exploited natural resource. Canada as a whole "has far more water underground than on the surface - perhaps 65 times more than in surface lakes and streams",(Gorrie 70-71), and the same holds true for ...

... Glasswort is the dominant plant of Pacific Coast salt marshes. Freshwater marshes provide nesting and wintering habitats for waterfowl and shorebirds, muskrats, frogs, and many aquatic insects. Salt marshes are wintering grounds for snow geese and ducks, a nesting habitat for herons and rails, and a source of nutrients for estuarine waters. Marshes are important in flood control, in sustaining high-water tables, and as settling basins to reduce pollution downstream. Despite their great environmental value, marshes are continually being destroyed by drainage and filling. Marine Life, plants and animals of the sea, from the high-tide mark along the shore to ...
