Circular motion - Uniform circular motion. 1  In physics, uniform circular motion describes the motion of a body traversing a circular path at constant speed. Since the body describes circular motion, its distance from the axis of rotation remains constant at all times.
During deficiencies, thiamin is retained in greatest quantities in major organs such as the liver, heart, brain and kidneys. Although liver and kidney tissues have the highest thiamin concentrations, approximately one-half of the total thiamin body stores are present in muscle tissue (Tanphaichir, 1976).
Thiamine was one of the first compounds recognized as a vitamin. Thiamine is involved in many body functions, including nervous system and muscle function, the flow of electrolytes in and out of nerve and muscle cells, digestion, and carbohydrate metabolism. Very little thiamine is stored in the body and depletion can occur within 14 days. Severe thiamine deficiency may lead to serious complications involving the nervous system, brain, muscles, heart, and stomach and intestines. Dietary sources of thiamine include beef, brewer's yeast, legumes (beans, lentils), milk, nuts, oats, oranges, pork, rice, seeds, wheat, whole-grain cereals, and yeast. In industrialized countries, food made with white rice or white flour is often enriched with thiamine.
