Michael Devitter appeared in 1926 when Fujimaki (5) observed the development of carcinomas of the stomach in rats maintained on a vitamin A deficient diet. More recently, other investigators have shown that animals fed a diet deficient in retinoids and subsequently exposed to chemical carcinogens develop a greate

ent tumor promoter, 12-0-tetradecanoyl-phorbol-13-acetate (TPA), are known to be antagonized by agents which interact with free radicals, such as antioxidants. We have observed that . promotion by TPA can be enhanced by the presence of ferrous ions (Fe.) in the cellular medium. It is known that TPA

Advances in network performance have lagged considerably behind advances in Supercomputing performance. In fact, over the past 10

Michael Devittost often contradictory, explanations of this phenomenon have been proposed, mainly based on the degree of predictability and order of these communities (Smith, 1978; Sale, 1978; Bohnsack, 1983). However, species "richness" of reef fish communities also differs according to both geographic areas and

As will be shown in later chapters, the concepts introduced and the techniques developed for the analysis of single degree of freedom systems can be generalized to study discrete systems with multi-degrees of freedom as well as continuous systems. For this volume to serve as an
