George E. Inglett of the U.S. Department of Agriculture's Biopolymer
Research Unit in Peoria III invented a no-calorie fat substitute called Z-Trim.
It is a mix of crushed fibers made from the hulls of grains. It can replace the
fat and some of the carbohydrates in foods such as chocolates, brownies, cheese,
and ground beef. He spent three years trying to perfect Z-Trim to be smooth
because he made it out of tough hulls of corn, oats, and rice. He first crushed
the hulls with a solution of hydrogen peroxide. He washed the peroxide off in
centrifuge. After this step it was still too large, so he put the pieces back
through the first step of the hydrogen peroxide and the centrifuge. That made
it smooth. Now, it is a fine, white cellulose powder that can be made into a
gel by adding water.
Inglett also developed Oatrim. This is made up of a digestible fiber
from oat flour that provides four calories per gram.

I'm about to take up a position which is going to be deamed by some, if not all, as a terrible stand to take. As a matter of fact, if anyone were to agree with me on ths subject, I'd be surprsed. For you see, rather than arguing from the postion of suicide being an unjustified and inane way to die, I shall argue the other point. That being suicide...

'Insomnia is...
Athletes today will do almost anything to get an edge. In the past athletes had to turn to such things as anabolic steroids or blood doping (the process of taking out blood and adding oxygen to it and putting it back into your body in order to increase a persons endurance). However, these procedures have many drawbacks. Mainly, they are illegal....
Intelligence is defined as 'the possession of knowledge, the ability to efficiently use knowledge to reason about the world, and the ability to employ that reasoning adaptively in different environments' (Bernstein, Clarke-Stewart, Roy, and Wickens, 1997,pp. 304). But can we accurately measure intelligence? There are a vast variety of Intelligenc...
Is there ? Previous research in the field has suggested that the majority of the consultations conducted by sport psychologists be related to anxiety (Humara 1999). This is a large part of the athletes' own mind-set. It is necessary for him or her to demonstrate the ability to deal with the pressure and anxiety that comes with the game. There i...

This project is worthwhile because not many people are aware of this disorder, and therefore, do not know how to deal with it. My intended audiences are adolescents who may be experiencing some of the borderline symptoms, and those affected by , whether they themselve...
What would it be like to die so young and so fragile? What would it be like to kill something so young and so fragile? Abortion, in my definition, is the taking of a life. Now it is hard for me to sit here and type this paper when I know good and well that if my daughter or wife were ever raped I would want whatever was inside of them out -- imm...
