... self-organizing network (Arbib, 1995). In 1943 McCulloch and Pitts published their model theory ( Arbib, 1995). In 1948 Rashevsky proposed a number of neural network models to explain psychological phenomena. During this era not enough was known about the brain, subsequently he was considered ahead of his time. Rashevsky relied heavily upon complex mathematical equations within his model, consequently many people simply did not understand his theoretical perspective ( Martindale, 1991). In 1958 Rosenblatt proposed his theory on neural network models which focused on perception. The theory elicited a great deal of interest; however it was considered too simple t ...

... of pesticide usage universally, society can never be sure as to the long term effects on our environment and what they are eating or giving to the future of our world, the children. In some foreign countries pesticides are used more frequently with legislative control than in the United States. In Mexico and South America, for example, many of the pesticides that the United States and Europe have banned, wind up being used on a majority of their produce crops. The largest problem with this is that Europe and the United States import from South America for produce all of the time. What good does it do to ban harmful agricultural chemicals to be used on domestical ...

... is given to what foods should be avoided, which to eat in moderation and those to be liberally consumed. It is stated by Newkarm that general health requires that the total intake of all fats, especially animal fats is reduced. Fatty deposits in the arteries and gallstones are to a large extent made up of cholesterol (19). When foods high in fat content are eaten, excessive amounts of cholesterol are made in the body. Individuals who have fat concentrated in the waist and abdomen instead of thighs and buttocks are prone to diseases that accompany obesity (Pruitt 121). Some of these diseases are: (in females) cancer of gallbladder, breast, uterus, and o ...

Another student held up a napkin soaked with grease from a piece of pizza served at his school! Other students complained about canned vegetables being drenched in butter(Norvell, 1995). Many of the school meals sacrifice taste and appearance. When this happens it leads to the children to neglect their main course and go to class hungry. In a study conducted for The American School Food Service Association and sponsored by Sabetasso Foods, taste of food was the number one variable influencing the decision t ...

... reached a plateau of 25-35 Ohm.cm2, which was similar to the small intestine. In transport studies 2/4/A1 cell line monolayers selectively restricted the permeation of hydrophilic permeability markers proportional to molecular weight and discriminated more accurately between the molecules of intermediate molecular weight compared to Caco-2 cells. These results indicated that 2/4/A1 cells could be used as a model for hydrophilic drug absorption. INTRODUCTION The small intestine plays a crucial role in the absorption of drugs and nutrients. Exogenous substances cross a series of barriers during the process of intestinal absorption: (1) the aqueous boundary/mucu ...

... Wistar rats were injected with increasing amounts of minced pancreas from unrelated donor rats for one year while a control group was left untreated. Then both the treated and control groups received injections of approximately 500-800 islets of Langerhans from unrelated donors. Of the five treated animals, two became clinically and biochemically permanently normal. Six months later, Martin examined the cured rats and found intact, functioning islets secreting all of their hormones, including insulin. None of the controls were cured. Encouraged by their first results, Leibel, Martin, and Zingg decided to repeat the experiment with rats with much stronger immune b ...

... no more than the width of the folded side of a piece of paper seen end on! Imagine trying to sew two pieces of spaghetti together and you'll have some idea of what microsurgery involves. Twenty-five years ago, this man's thumb would have been lost. But in the 1960s, surgeon's began using microscopes to sew what previously had been almost invisible blood vessels and nerves in limbs. Their sewing technique had been developed on large blood vessels over a half century earlier but could not be used in microsurgery until the needles and sutures became small enough. The surgical technique, still widely used today, had taken the frustrating unreliability out of sewin ...
