.... Acid rain, the pH of a normal lake ( 5.8 ) to 4. Acid Rain has been known to reach the acidicy of pH 2, ( battery acid has a pH if 1 ) this is a drastic change, as normal rain is average pH 5.2. Acid Rain can dissolve limestone and chalk, and corrodes outdoor structures. Statues and monuments that are left unprotected can fall victim to the unpredjudiced destruction of acid rain. Acid Rain reacts to different types of soil and rocks in two ways. 1) Acid rain will dissolve alkaline rocks and soil, or will neutralize the alkalinity. 2) Acid rain will increase the acidicy of already acidic rocks and soil, such as granite, or the soil which results from corroded granite. ....

.... a congruent word was present. Therefore pictures activate the name code. Another experiment (Experiment 2) indicated that memory for pictures and words, whether they were initially named or categorized had an effect on memory. Memory was better for words if they have been categorized and for pictures if they have been named. Experiment 3 showed the same results as the previous two experiments. The fourth experiment, with the introduction of less common objects, subjects could name the words faster than generating a category name for the words. Naming pictures are prone to interference when incongruent words are presented simultaneously. Word naming is not as much inf ....

.... on end getting in and out of those little white suits and rubber gloves to dispose our radio active waste. It is not so much that we recognize the great discoveries and creations we have made, but more that we recognize all we do as humans to ensure our plentiful and gluttonous lifestyles. Lets face it. We as humans waste countless hours of our lives worrying about the future. Whether it’s asteroids or Y2K, it’s always something. It is said that in the future, with global warming, temperatures outdoors will be too hot to survive in. But what is the future? Is the future tomorrow, maybe next month, or next century? The fact is by the time all of the proble ....

.... dream up incredible uses for this technology including using it as a sort of drug. This became evident when, among other people, Timothy Leary became interested in VR. This has also worried some of the researchers who are trying to create very real applications for medical, space, physical, chemical, and entertainment uses among other things. In order to create this alternate reality, however, you need to find ways to create the illusion of reality with a piece of machinery known as the computer. This is done with several computer-user interfaces used to simulate the senses. Among these, are stereoscopic glasses to make the simulated world look real, a 3D auditory displa ....

.... FAS have prenatal and postnatal birth deficits, central nervous system dysfunction, specific facial characteristics, and body malformation problems. Children who display only some of these effects are claimed to have FAE, or fetal alcohol effects. 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 pro ....

.... the Shubenacadie river to display the true Bay's magnificence. This part of St. John is divided into 3 main areas: the main Harbor, Courtenay Bay and the Outer Harbor. These areas are influenced by the Bay of Fundy tides and the currents of the St John River which flow out of the main Habour into the Bay. This section also experiences two high and two low tides each day (semi - diurnal), with a tidal range varying from 15 to 18 feet, depending on the type of tides. High - water heights vary from 22 to 28 feet and low - water heights vary from 0 to 7 feet above chart data. Because of these semi - diurnal tides and the action of the St John River, slack water in the Habour ....

.... is a very important issue in the world today. Billions of people have an on-ramp to the Information Superhighway, and more are finding one every day. The Internet transcends geographical locations, and is the first example of a true global village. Unfortunately for regular users of the Internet, much like the real world, criminals exist on the Internet as well. "Hackers," the computer wizards who use their knowledge for evil, are rampant on the Internet. Sometimes they do seemingly harmless acts, such as just going into a computer system and observing, but at other times, they steal, destroy or alter data. On some occasions, these cyber-felons perform even more malicious ....

.... jaws and equipped with a piston like tongue that creates suction when the mouth is placed against an object, and the tongue is drawn back. In the inner part of the mouth and the edges of the tongue, there are many small, horny teeth. These are what the lamprey uses to pierce the flesh of fishes. The adult forms of lamprey die soon after spawning and reaching their mature form. Lampreys mostly live in freshwater streams and seas of temperate and subartic regions throughout the world, except for Southern Africa. The sea lamprey is a marine species. They are native to the Atlantic Coast of North America and Europe. In many areas it has adapted to a life cycle spent en ....
