Although many view toxicology as a new science, since man discovered the medicinal properties of plants, it has been known that such materials could produce toxic effects. Recently, developments in analytical chemistry have advanced and specialized the field of toxicology. The analytical chemical approach has altered our thinking. We have become able to recognize smaller and smaller quantities of more and more chemicals. At times it would appear that this analytical approach has blunted our perception of the biological aspects of toxicology. In reality, newer developments have afforded broader insights and a wider range of concerns that are emphasized in this state-of-the-art text. Such conc...
The second edition of this textbook provides a single source for the analysis of system models represented by continuous-time and discrete-time, finite-dimensional and infinite-dimensional, and continuous and discontinuous dynamical systems. For these system models, it presents results which comprise the classical Lyapunov stability theory involving monotonic Lyapunov functions, as well as corresponding contemporary stability results involving non-monotonic Lyapunov functions. Specific examples from several diverse areas are given to demonstrate the applicability of the developed theory to many important classes of systems, including digital control systems, nonlinear regulator systems, puls...
It is with great pleasure that I offer my reflections on Professor Anthony N. Michel's retirement from the University of Notre Dame. I have known Tony since 1984 when he joined the University of Notre Dame's faculty as Chair of the Depart ment of Electrical Engineering. Tony has had a long and outstanding career. As a researcher, he has made im portant contributions in several areas of systems theory and control theory, espe cially stability analysis of large-scale dynamical systems. The numerous awards he received from the professional societies, particularly the Institute of Electrical and Electronics Engineers (IEEE), are a testament to his accomplishments in research. He received the IEE...
In the analysis and synthesis of contemporary systems, engineers and scientists are frequently confronted with increasingly complex models that may simultaneously include components whose states evolve along continuous time and discrete instants; components whose descriptions may exhibit nonlinearities, time lags, transportation delays, hysteresis effects, and uncertainties in parameters; and components that cannot be described by various classical equations, as in the case of discrete-event systems, logic commands, and Petri nets. The qualitative analysis of such systems requires results for finite-dimensional and infinite-dimensional systems; continuous-time and discrete-time systems; cont...

The Permanent Commission and International Association on Occupational Health (PCIAOH) established in 1969 a Subcommittee on the Toxicology of Metals under the chairmanship of Lars Friberg. This committee, which later was named the Scientific Committee on the Toxicology of Metals, has organized a number of previous meetings that have led to publications in three major areas of metal toxicology: a preliminary meeting in Slanchev Bryag, Bulgaria in- 1971, followed by a meeting in 1972 in Buenos Aires, Argentina which produced two reports (Dukes and Friberg, 1971; Task Group on Metal Accumulation, 1973), that discussed the metabolism of metals with special reference to absorption, excretion and...
In recent years there has been an enormous growth of interest in the proteins produced by the trophoblast and, most recently, the endometrium, since the knowledge of placental and endometrial proteins is essential for the understanding of the physiology of reproduction. This volume contains reports by 25 internationally renowned experts in this field presented at the 6th International Congress of Placental and Endometrial Proteins which was held in Nagoya, Japan, 1--3 December 1987. Additionally, these proceedings give a unique overview of research done in Japan by publishing over 70 papers by Japanese researchers.
Traditionally, in the food industry, there has been a distinction made among meat, poultry, seafood, and game. Meat has historically been defined as the edible flesh of animals. This basically referred only to the red meats, namely, beef, lamb, pork, and veal, including both fresh and processed products as well as variety or glandular meats. It has been recognized more recently that all foods derived from muscle, or muscle foods, have basically the same or similar characteristics in physical and chemical properties. Tberefore, it is logical to exarnine and consider all muscle foods under one cover. Tbis book, therefore, is an attempt to address the various attributes of red meat, poultry, fi...
