Neuware -Determinantal rings and varieties have been a central topic of commutative algebra and algebraic geometry. Their study has attracted many prominent researchers and has motivated the creation of theories which may now be considered part of general commutative ring theory. The book gives a first coherent treatment of the structure of determinantal rings. The main approach is via the theory of algebras with straightening law. This approach suggest (and is simplified by) the simultaneous treatment of the Schubert subvarieties of Grassmannian. Other methods have not been neglected, however. Principal radical systems are discussed in detail, and one section is devoted to each of invariant and representation theory. While the book is primarily a research monograph, it serves also as a reference source and the reader requires only the basics of commutative algebra together with some supplementary material found in the appendix. The text may be useful for seminars following a course in commutative ring theory since a vast number of notions, results, and techniques can be illustrated significantly by applying them to determinantal rings.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 248 pp. Englisch.

Neuware -From the preface: 'These proceedings contain 73 contributed papers selected from among those presented at the 13th IFIP Conference System Modelling and Optimization, Tokyo, Japan, August 31 - September 4, 1987, as well as 4 papers for the plenary sessions of the Conference. The aim of the conference was to discuss recent advances in the mathematical representation of engineering, sociotechnical, socioeconomic systems as well as in the optimization of their performances.'Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 804 pp. Englisch.

Neuware -Early in 1985, a meeting was held to discuss the organization of a work shop in honour of Professor Reinier L. Zielhuis on the occasion of his retirement on November 30,1986. Various themes for such a workshop were considered, but it was Zielhuis himself, who ultimately selected 'Health surveillance of individual workers exposed to chemical agents' as the theme of the workshop. Although this topic is of the utmost im portance for occupational health practice, it is also a very difficult one, given our currently limited knowledge on the subject. The choice of this topic is characteristic of Reinier Zielhuis, a scientist and scholar who throughout his career has been deeply concerned with the health and health risks of workers. Because he regards occupational and environmental exposure - including life style - as two aspects of the total exposure to chemical and physical factors, he emphasizes the need to assess the impact of this total exposure on workers' health. The impact of total exposure probably detennines to a large extent the in dividual variability in response. This was the main reason why he selected the above-mentioned topic for the workshop.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 176 pp. Englisch.

In the realm of analysis for engineering design the finite element method has emerged as a powerful tool for modeling and analysis of solids and structures of complex geometries and variable material properties in many areas of engineering design such as machine components, pressure vessels, nuclear reactors, off-shore structures, steel and concrete buildings, bridges, towers, automobile components, turbine parts, power plant structures, etc. The text-book literature on the finite element method exists at an introductory level through the new and more advanced level of simple applications. Modeling and analysis of practical problems continue to be developed and published in technical journals. Developments are also taking place in the use of artificial intelligence techniques in expert systems to advise the analysts on the choice of the elements, type of analysis, discretization, etc. for solving complicated problems. It is essential to periodically synthesize all the developments on the finite element method and its applications to practical problems of engineering design and also to identify the future areas of research both in the domains of academic research and industrial applications. Keeping this in mind an advanced study institute was organized at Indian Institute of Technology, Madras, India during Aug. 1-10, 1988. This volume contains lecture notes prepared by the invited lecturers attending the Advanced Study Institute. It should serve as a ready reference to researchers and practitioners engaged in the finite-element analysis related to engineering design in several disciplines.'Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 892 pp. Englisch.

STUMPE Following the discovery of the pentapeptide enkephalins in 1975, a number of endogenous opioid peptides and opiate receptors have been identified. Endogenous opioids and opiate-receptor mechanisms have been implicated in a variety of regulat ory and dysregulatory functions including analgesia, cardiovascular regulation, shock, hypertension, traumatic spinal cord and brain injury, stroke, immune func tion, feeding behavior, diuresis, gastrointestinal motility, and respiratory control, among others. Over the past 10 years, many studies have demonstrated a relationship between endogenous opioids and the cardiovascular system under both homeostatic and pathophysiological conditions. Opioids and opiate receptors have been found in various cardioregulatory sites within the brain and spinal cord, as well as in peripheral tissues such as sympathetic ganglia, adrenal gland, and heart. Both endogenous opioids and exogenous opiates have been shown to produce potent cardiovascular effects following central nervous system or systemic administration. Opiate-receptor antagonists have been demonstrated to reverse hypotension from sepsis, hypo volemia, and anaphylaxis; such studies have been used to infer activity of endogenous opioid systems in shock. Changes in tissue concentrations of endogenous opioids and! or opiate receptors have been found after shock and hypertension, further implying a role for opioid systems in the etiology of these conditions. In addition, modification of opiate receptor regulation, receptor binding, or opioid metabolism has also been used to establish a potential role for endogenous opioid systems in cardiovascular control and dyscontrol.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 312 pp. Englisch.
