.... to us every day of our lives. According to the Water Quality Association, approximately “15percent of the Canadian population relies on individually owned and operated sources of drinking water, such as wells, cisterns and springs. On the other hand about 80percent of the population receives water from a community system”(1). Household pumps and community water systems a generally used by the majority of consumers. Household pumps are designed to pump ground water for household use, while a community system may use surface water or ground water .....

.... The sad thing is that most infants and children who suffer from fetal alcohol effects go unnoticed. They are looked upon as having behavioral problems. Because of this lack of recognition the treatment of their problems are mishandled which creates a very difficult and confusing childhood for these children. (McCreight, 1997). Even when fetal alcohol effects are recognized there is limited treatment. There are hardly any programs in schools and society to help the children maintain normalcy. It was not until 1973 that the deficit was first acknowledged and .....

.... though not genetically—so a clone is a separate person from his or her non-contemporaneous twin. To think otherwise is to embrace a belief in genetic determinism—the view that genes determine everything about us, and that environmental factors or the random events in human development are utterly insignificant. The overwhelming consensus among geneticists is that genetic determinism is false. As geneticists have come to understand the ways in which genes operate, they have also become aware of the myriad ways in which the environment affects their "expres .....

.... be an automatic process, this occurs when little or no effort, without awareness, and without interfering with our thinking about other things. Encoding can also be effortful processing; although we encode an enormous amount of information unintentionally, many other types of information we remember only with much effort, rehearsal, and attention. We can forget things because of encoding failure. Sometimes we fail to encode information, so it never entered the memory system, short-term or long-term memory. A vast amount of what we sense, we never notice o .....

.... all the situations that confront an engineer, mechanics lie at the core of much engineering analysis. In fact, no physical science plays a greater role in engineering than does mechanics, and it is the oldest of all physical sciences. The writings of Archimedes covering bouyancy and the lever were recorded before 200 B.C. Our modern knowledge of gravity and motion was established by Isaac Newton (1642-1727). Mechanics can be divided into two parts: (1) Statics, which relate to bodies at rest, and (2) dynamics, which deal with bodies in motion. In this p .....

.... to be matched by mixtures of only three color sensitivities. Therefore, the huge variety of colors we see are a response to different compositions of wavelengths of light. The rods are responsible for encoding white and black. results when one or more of the cone cells fail to function properly. One of the visual pigments may be functioning abnormally, or be absent altogether. There are several different types of , however, complete , or achromatopsia, is probably the simplest to understand. This is the rarest form of . This is when no colors can be seen .....

.... climates (Siberian ) have thicker fur than that live in warm climates. A tiger's tail is 3 to 4 feet long, about half as long as its body. use their tails for balance when they run through fast turns. They also use their tails to communicate with other . Where did tigers come from? Tigers (and all other carnivores) are descended from civet-like animals called miacids that lived during the age of the dinosaurs about 60 million years ago. These small mammals, with long bodies and short flexible limbs, evolved over millions of years into several hundred differ .....

.... happen after many years of use. Power projects (later AECL CANDU), based in Toronto. Ontario and Montreal, Quebec became responsible for implementing AECL’s nuclear power program and marketing CANDU reactors. Nuclear power was cheap, if you did not have to worry about the waste. This was the answer to Ontario’s power problems, so they invested in the newest source of power at the time. Most people believed that nuclear power was a good change in Ontario’s power structure, and there would be no real problems in the future. Ontario needed a n .....
