Providing an overview of the main types of polymeric materials used in engineering, this text discusses their applications - both practical and potential.

Linear programming is a relatively modern branch of Mathe matics, which is a result of the more scientific approach to management and planning of the post-war era. The book assumes that the reader is familiar with matrix algebra and the background knowledge required is covered in the book, Linear Equations by P.M.

An introduction to the entire process of pressing sheet metal into various shapes, which considers the subject mainly from a mechanical engineering viewpoint. Each main sheet alloy is dealt with at varying lengths, depending on its industrial popularity.

The limnological study of Toolik Lake began in the Summer of 1975. This research was an outgrowth of the arctic IBP project which had focused mainly on small Arctic pond ecosystems on the Alaskan Arctic coastal plain. It was thought desirable to study larger, deeper lakes which contained fish to further generalizations developed during the IBP study. Initial research on Toolik Lake and the surrounding lakes and ponds focused on process studies such as annual primary productivity of the lake or the vertical migration patterns of the resident zooplankton. In 1983 the philosophy of the research changed with the funding of a more integrated programme. The fundamental question posed was whether Arctic lake and stream ecosystems are regulated from the bottom up by nutrient availability or from the top down by the density and activity of top predators. In 1987 the Toolik Lake area was designated an LTER (Long-Term Ecological Research) site, one of 18 such sites throughout the United States, Puerto Rico and the Antarctic. The research theme for the Arctic LTER also focuses on the regulation of Arctic ecosystems, whether regulation comes from the top down or bottom up. The Arctic LTER also incorporates a terrestrial component as well as a lake and stream component.

This introduction to industrial chemistry provides an overview of what industrial chemistry does, showing the most important aspects. It examines chlor-alkali products, covering a major sector of the inorganic chemicals industry.

From the tone of the report by the President's Commission for the Study of Ethical Problems in Medicine and Biomedical and Behavioral Re­ search, one might conclude that the whole-brain-oriented definition of death is now firmly established as an enduring element of public policy. In that report, Defining Death: Medical, Legal and Ethical Issues in the Determination of Death, the President's Commission forwarded a uni­ form determination of death act, which laid heavy accent on the signifi­ cance of the brain stem in determining whether an individual is alive or dead: An individual who has sustained either (1) irreversible cessation of circulatory and respiratory functions, or (2) irreversible cessation of all functions of the entire brain, including the brain stem, is dead. A determination of death must be made in accordance with accepted medical standards ([1], p. 2). The plausibility of these criteria is undermined as soon as one confronts the question of the level of treatment that ought to be provided to human bodies that have permanently lost consciousness but whose brain stems are still functioning.

Some 35 years ago I was somewhat precariously balanced in a drilling derrick aligning a whipstock into a directional hole in North Holland by the Stokenbury method, and no doubt thinking to myself that I was at the very forefront of technology.

The contributions to this special collection concern issues and problems discussed in or related to the work of Wesley C. Salmon. Salmon has long been noted for his important work in the philosophy of science, which has included research on the interpretation of probability, the nature of explanation, the character of reasoning, the justification of induction, the structure of space/time and the paradoxes of Zeno, to mention only some of the most prominent. During a time of increasing preoccupation with historical and sociological approaches to under­ standing science (which characterize scientific developments as though they could be adequately analysed from the perspective of political movements, even mistaking the phenomena of conversion for the rational appraisal of scientific theories), Salmon has remained stead­ fastly devoted to isolating and justifying those normative standards distinguishing science from non-science - especially through the vindi­ cation of general principles of scientific procedure and the validation of specific examples of scientific theories - without which science itself cannot be (even remotely) adequately understood. In this respect, Salmon exemplifies and strengthens a splendid tradi­ tion whose most remarkable representatives include Hans Reichenbach, Rudolf Carnap and Carl G. Hempel, all of whom exerted a profound influence upon his own development.

For the most part, the papers collected in this volume stern from presentations given at a conference held in Tucson over the weekend of May 31 through June 2, 1985. We wish to record our gratitude to the participants in that conference, as well as to the National Science Foundation (Grant No. BNS-8418916) and the University of Arizona SBS Research Institute for their financial support. The advice we received from Susan Steele on organizational matters proved invaluable and had many felicitous consequences for the success of the con­ ference. We also would like to thank the staff of the Departments of Linguistics of the University of Arizona and the University of Massachusetts at Amherst for their help, as weIl as a number of individuals, including Lin Hall, Kathy Todd, and Jiazhen Hu, Sandra Fulmer, Maria Sandoval, Natsuko Tsujimura, Stuart Davis, Mark Lewis, Robin Schafer, Shi Zhang, Olivia Oehrle-Steele, and Paul Saka. Finally, we would like to express our gratitude to Martin Scrivener, our editor, for his patience and his encouragement. Vll INTRODUCTION The term 'categorial grammar' was introduced by Bar-Rillel (1964, page 99) as a handy way of grouping together some of his own earlier work (1953) and the work of the Polish logicians and philosophers Lesniewski (1929) and Ajdukiewicz (1935), in contrast to approaches to linguistic analysis based on phrase structure grammars.

England The main aim of this series will be to illustrate and to explain the way organisms 'make a living' in nature.

With the growth of modern computing power it has become possible to apply far more mathematics to real problems. This has led to the difficulty that many people who have been working in various jobs suddenly find themselves not understanding the modern processing which is being applied to their own professional field.

The experience on the captan committee did little to reassure me, either about captan or about the way that decisions had been made about many pesticides in widespread use. Prudence required at the very least that consumers take the precaution of washing their fruit, for captan is widely used on apples, cherries and berry fruits.

Although the name Pithecanthropus is now seldom used, there are few who study the origin of our species who will fail to recognise the historical place of the usage and its association with Eugene Dubois.

The study of plant development in recent years has often been concerned with the effects of the environment and the possible involvement of growth substances. The prevalent belief that plant growth substances are crucial to plant development has tended to obscure rather than to clarify the underlying cellular mechanisms of development.

Economic plants have been defined by SEPASAT as those plants that are utilised either directly or indirectly for the benefit of Man.

This work is based on my 1983 doctoral dissertation submitted to the Department of Linguistics at Harvard University, although it represents an extensive revision and reorganization of that work.

Chapter 7 is about the patterns of vegetation change which occur in severe habitats around the world, and Chapter 8 discusses wetlands. The final chapter, Chapter 13, draws the diverse themes together into a unified theoretical structure by which the vegetation change phenomena may be understood.
