This item is printed on demand - it takes 3-4 days longer - Neuware -When I entered the graduate program in philosophy at the University of Pittsburgh in 1961, Nicholas Rescher had just joined the department of philosophy' to begin, with Adolf Grunbaum, the building of what is now a philosophy center of worldwide renown. Very soon his exceptional energy and versatility were in evidence, as he founded the American Philosophical Quarterly, generated a constantly rising stack of preprints, pursued impor tant scholarly research in Arabic logic, taught a staggering diversity of histori cal and thematic courses, and obtained, in cooperation with Kurt Baier, a major grant for work in value theory. That is all part of the record. What may come as a surprise is that none of it was accomplished at the expense of his students. Papers were returned in a matter of days, often the next class meet ing. And so easily accessible was he for philosophical discussion that, since (inevitably) we shared many philosophical interests, I asked him to serve as my dissertation advisor. My work in connection with this project led to a couple of journal articles while his, characteristically, led to a book. Our dis cussions certainly helped me, and while they may also have had some small influence on him, in the end our views were quite distinct. I was not only allowed complete independence, but was positively encouraged to think of my own ideas and to develop them independently. The length and breadth of Rescher's bibliography defy belief. 252 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Going ahead with their plans, the Association for Research on Schizophrenia CARS), the Schizophrenia Research Group of the Institute of Psychiatry of the University of Milan and the Tito and Fanny Legrenzi Foundation organized the International Meeting 'Etiopathogenetic Hypotheses of Schizophrenia: The Impact of Epidemiological, Biochemical and Neuromorphological Studies', held in Milan on October 3-4 1986. The Meeting was an excellent occasion for the exchange of information and the sharing of views on the etiological hypotheses of schizophrenia resulting from the latest research in the key areas of epidemiology, biochemistry amd brain imaging. We are very pleased and proud to have had so many of the leading researchers in schizophrenia with us. Their stimulating and friendly presence and their contributions made this Meeting a great success. We hope that this book, a collection of the various participants' contributions at the Meeting, will have an equally favourable reception. The Editors viii List of contributors N. C. Andreasen A.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In November 1988 the ''Third Oberursel Symposium' devoted to the problems of input of pollutions into forest-ecosystems and their effects on plants or soil convened. After several years of intensive research on the effects of pollutions on forest ecosystems it is obvious that not a single specific pollutant can be made responsible but a mixture of several components act together or interact with each other. The contributions of the workshop _ reflect to a large extend the results of research projects which were started at the beginning of the eighties. They review our improved knowledge on the patterns of concentration, of the mechanism of wet and dry deposition and fog interception, modelling studies and the effect of the processes on plant receptors and surfaces. Since the 1985 symposium the pathways of pollutants leading to biological damage have been examined and are more clearly recognised. The book reflects the common interest and the continuous effort of scientists from many different disciplines to better understand the physical and chemical processes which finally lead to the observed damage of forest-trees. Comparing the conclusions of the contributions of this book _ with the results of the first Oberursel symposium in 1981, our knowledge on the relevance of the different mechanisms leading to forest-decay has been considerably improved. The book indicates also in which directions future work should be concentrated. Again, I have to thank the authors for their cooperation by submitting their recent research-results. 376 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Meteorology is by nature a multidisciplinary and transnational subject and COST cooperation has proved to be a flexible and suitable framework at European level for meteorological activities such as the standardisation of observation techniques and harmonised transmission of meteorological data. Although meteorology is not covered by a specific Community programme as such, various Community actions dealing with meteorology are now included in the EEC research programme on climatology (the 'EPOCH' programme - 1989-92) of mechanisms of extreme and sudden concerning particularly the study meteorological events, in order to predict catastrophies and consequently to reduce human and material losses. In the context of COST cooperation, which is supported by the Commission of the European Communities, the COST 73 project (1986-1991) associates 16 countries in Western Europe with the aim of setting up a weather radar network providing real-time measurements of rain, snow or hail precipitations. In this project, radar data are transmitted and combined if appropriate with satellite data - in one or more 'compositing centres' of the participating countries, in order to improve weather forecasting. Together with the COST 73 Management Committee, the Commission of the European Communities organized a seminar on this matter, in Brussels on 5-8 September 1989, at the half-way stage of the project. 600 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Three points must strike anyone who has embarked on a study of dementia over a period of time. Firstly, that our conception of the syndrome is in a state of flux. Gone, for instance, in the past decade or two, is the requirement of a chronic, progressive, irreversible disorder for the diag nosis. I remember the surgeon who, when I was a student, returned a referral saying he would operate on the man when his dementia got better. Feeling superior, and encouraged by the consultant psychiatrist, we students laughed a good deal at this. Before we finished clerking on that Unit a visiting Professor of Psychiatry had demonstrated the reversibility of the symptoms of dementia in a patient with a rare metabolic disorder. Perhaps ignorance is sometimes an advance on received wisdom. The lesson is the concept of dementia must always reflect the state of knowledge and is therefore in a sense ad hoc. Secondly, what the criteria for, and also who the arbiters of, the diagnosis might be is not always clear. It is traditional to think that expressing opinions and making diagnosis of mental illness is almost a civic right, i.e. 244 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -International shipping is of great importance for the transport of a great many types of cargo. Substances and products considered dangerous constitute almost 50% of all the payload. It is obvious that stringent regulations are required in order to minimize the risks of accidents. These regulations, which are derived from good practice and which are based on research, have been adopted by a great number of countries. However, emergencies do occur in spite of all precautions. Such emergencies require fast and adequate response in order to confine the consequences for man and his environment to a minimum. Emergency response has political, legal, financial and technical aspects. This makes decision making extremely difficult. The papers carefully prepared and assembled in this book present an up-to-date picture of today's achievements, knowledge and difficulties that are being faced. It was the intention of Oilchem Recovery Denmark and TNO to bring the wide scatter of aspects together in a joined perspective. We also intended to spread the information on latest developments among the many people who are involved in combating calamities and in particular in decision making. Finally, we hope that this conference may help all of us to come to a safer transport of chemicals and a better aquatic environment. We thank all the authors for their magnificent contribution. 504 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Reproduction and fetal development in humans and experimental animals may be adversely affected by a wide range of drugs and environmental agents. They may be toxic in the parental generation leading to impaired germ cell formation, loss of reproductive poten tial and infertility following chronic exposure. Deviant fetal development occurs as a consequence of cellular damage at sensi tive stages in development. Changes seen range from intrauterine mortality and structural malformation to growth retardation with physiological and behavioural defects. Concepts on the mechanism of action of teratogens are discussed with reference to some better-known agents. Presently, regulatory authorities prefer whole animal studies in predictive safety evaluation of substances to which a pregnant woman may be exposed. Tests are conducted over one or more generations and are designed to study the influence of test com pounds upon general reproductive performance, fertility, fetal development and perinatal and postnatal behaviour. Experiments are designed to permit compounds to be tested under conditions resembling expected human exposure. Small rodents and rabbits are preferred species on account of their convenience as laboratory animals and the available knowledge regarding their reproductive behaviour, fetal development and known sensitivity to human teratogens. 324 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The last decade has seen tremendous developments in many fields of gastroenterology and hepatology. The aim of this series is to highlight some of these topics that deserve particular interest. Research in the field of viral hepatitis has been very intense and successful in recent years. The hepatitis B virus is one of the best explored at the current level of virology. Not only the nucleotid sequence of the viral DNA can be decoded, but also the amino acid compounds of its genetic products are known today. Since the techniques of molecular biology have increasingly found access to clinical laboratory use, hepatitis B virus infection can serve as an example for the importance of molecular biology in clinical hepa tology. Another example for the interdependence of basic science and clini cal medicine represents the research on bile acid metabolism. The investigation of bile acids has revealed new diagnostic approaches to hepatic and intestinal disorders. Commercial kits for the routine measurement of serum bile acids in clinical laboratories by enzymatic or radioimmunologic techniques are now available. The diagnostic value of these measurements in gastroenterology and hepatology shall be defined. Another aspect of bile acid research leads to new per spectives in the treatment of gallstone disease. The dissolution of cholesterol gallstones by chenodeoxycholic acid (therapy) may be quoted as the best example for the development of new phar macotherapeutic principles derived from basic bile acid research. 156 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -1985 and 1986 were milestones for those who study atherosclerosis. In those years took place the USA Consensus Conference, followed first by the Italian Consensus Conference and then by the European one. They marked the final solution to the 'querelle' on cholesterol and ischemic cardiopathy. On the basis of the results obtained from the Coronary Primary Prevention Trial (CPPT), plasmatic cholesterol is now no longer considered 'a' risk factor in cardiovas cular diseases, but 'the cause' of atherosclerosis and its organ damages. This was also the basic statement that came out of the 6th International Congress on 'Atherosclerosis and Cardiovascular Diseases'. The meeting was attended by specialists from various countries representing different experimental ap proaches to the cardiovascular diseases, from basic research (receptor pathol ogy, apoproteins physiopathology); to epidemiology (both observational study and prevention); to pure cardiology in its aspects of physiopathology, diagnosis and therapy; to the new invasive and non-invasive diagnostic methods; and to the presentation of studies which correlate new variables (serotonin, en dogenous opioids) with the atheromasic disease. The final outcome of this re search is therapy, be it a pharmacological, nutritional and/or surgical one. Il lustrious names from five continents dealt with a wide a range of topics, and their presentations produced a wealth of data. The presentations contained in this volume are the 'corpus' of the congress and will serve as a precise updat ing for all specialists, physicians and students. 592 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Rolduc Polymer Meetings, of which the contents of this volume represent the third, are already on their way to occupying a unique place in the crowded calendar of symposia on every aspect of polymer science and engineering. They combine manageable meeting size with a theme, 'Integration of Fundamental Polymer Science and Technology', which is often discussed but seldom realized in practice. The technological, or applied, areas of polymers have perhaps received more emphasis historically than those of other allied disciplines. Indeed, various plastic and rubber materials were successful items of commerce long before the macromolecular concept itself was firmly established. The more fundamental aspects of the field were also largely developed in industrial laboratories. The early work of Mark and Meyer at IG Farben, and that of Carrothers and Flory at Du Pont, are good examples of this. The present situation, in which polymers are being applied to more and more demanding end uses, from high performance materials on the one hand to the biomedical and electronics fields on the other, caIls for an ever greater understanding of the basic scientific principles governing their behavior. It is evident, therefore, that interactions between those engaged in the 'pure' and 'applied' parts of the field must be promoted effectively. The Rolduc Polymer Meetings contribute significantly to such interactions, not only by interweaving technological and scientific presentations, but also by providing a forum for the participants to discuss problems of mutual interest in all their complexity. 420 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Soon after the publication of my'Ontwakende W etenschap'the need for an English translation was felt. We were very glad to find a translator fully familiar with the English and Dutch languages and with mathematical terminol ogy. The publisher, Noordhoff, had the splendid idea to ask H. G. Beyen, professor of archeology, for his help in choosing a nice set of illustrations. It was a difficult task. The illustrations had to be both instructive and attractive, and they had t~ illustrate the history of science as well as the general background of ancient civilization. The publisher encouraged us to find better and still better illustrations, and he ordered photographs from all over the world, with never failing energy and enthusiasm. Mr. Beyen's highly instructive subscripts will help the reader to see the inter relation between way of living, art, and science of the ancient world. Thanks are due to many correspondents, who have suggested additions and pointed out errors. Sections on Astrolabes and Stereographte Projection and on Archimedes' construction of the heptagon have been added. The sections on Perspective and on the Anaphorai of Hypsicles have been enlarged. In the second English edition I have incorporated an important discovery of P. Huber, which sheds new light upon the role of geometry In Babylonian algebra (see p. 73). The section on Heron's Metrics (see p. 277) was written anew, follOWing a suggestion of E. M. Bruins. Zurich. 1961 B. L. 344 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this book two ethical systems are described in the language of mathematics. Ordinarily mathematics is thought to be a science of quantity. Indeed, manipulation of quantities constitutes much of mathematics. Elementary applied mathematics deals with reckoning and measurement, where concrete quantities are objects of attention, such as counting sheep or weighing corno But the operations on these quantities are performed with the help of symbols, from which concrete referents have been 'abstracted out': 3 + 5 = 8 regardless of whether the symbols stand for numbers of sheep or tons of corno Thus, the first principle that exhibits the power of mathematics is abstraction. It is one ofthe three pillars on which the edifice of mathematics rests. Another pillar is precision. Ordinarily, man communicates by words. W ords serve communication to the extent that they refer to things, events, states of affairs, feelings of the speaker, and so on. These are the meanings attributed to words. Communication is successful to the extent that the meanings coded upon words by the speaker correspond to the meanings decoded by the hearer. As is weH known, the degree ofthis correspondence varies enormously in different contexts of discourse and with the back grounds or attitudes of the speakers and hearers. Mathematics is a language in which the meanings ofthe symbols (the 'words' ofthis language) are absolutely precise. This precision is achieved by abstraction. Abstract terms are defined by their relations to other terms and by nothing else. 224 pp. Englisch.

Since the first conference at Irvine 'The computer in physics instruction' (1965). various meetings on this subject have been organized in many places, which dealt with very different subjects. Work groups have been set up at international level (by the UNESCO, OECD, . ) and at national level in various countries. Of the prominent extra-European meetings, we will only keep the most important ones. for example those held in the U.S.A. on the 'Computer Use in Undergraduate Curriculum' and in Canada, 'The Canadian Symposium on Instructional Technology' (1972). As a matter of fact, there have been quite a lot of conferences on this subject in Europe too. For example, the OECD entrusted us with the organizing of a center called U.C.O. 0.1. which would be aimed at two Objectives. On the one hand, to set up a aata bank on the experiments made in the field of the computer use in education; and on the second hand, to stimulate research in this field. 388 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The studies collected in this volume deal with the interpretation of opera. In most cases the results are based on structural analysis, a concept which may require some clarification in this context. During the past de cade 'structure' and 'structural' have become particularly fashionable terms lacking exact denotation and used for the most divergent purposes. As employed here, structural analysis is concerned with such concepts as 'relationship', 'coherence' and 'continuity', more or less in contrast to formal analysis which deals with measurable material. In other words, I have analysed the structure of an opera by seeking and examining factors in the musico-dramatic process, whereas analysts of form are generally preoccupied with the study of elements contained in the musical object. Though admittedly artificial, the dichotomy of form and structure may elucidate the present situation with regard to the study of opera. Today, nearly one hundred years after the death of Wagner, the proclaimed anti thesis of Oper und Drama is generally taken for what it really was: a means to propagate the philosophy of its inventor. The conception of opera (whether 'continuous' or composed of 'numbers') as a special form of drama is no longer contested. Nevertheless musical scholarship has failed to draw the consequences from this view and few scholars realize the need to study general theory of drama and more specifically the dramatic experience. 436 pp. Englisch.

Papua New Guinea is a parliamentary democracy, with a single legis lature known as the National Parliament (1). The State is divided into 19 provinces plus the National Capital District (Port Moresby) with de centralized Government established in each province. Before independence the country comprised the Australian territory of Papua in the southern regions and the United Nations Trust Territory of New Guinea in the North (1). Land area is 462,840 square kilometres This inclUdes the mainland, the three large islands of New Britain, ~ew Ireland and fiougainville plus 600 small islands and archipelagos. Approximate direct distances from the capital city of Port Moresby to some of the other centres are : Vanimo 990 km, Rabaul SOO km, Arawa 990 km and Lorengau S25 km. 1140 pp. Englisch.

But it must be admitted, that in contrast to physicists and chemists, 'quantum chemists' seem to be a rather ill-defined category of scientists. Quantum chemists are more or less physicists (basically theoreticians), more or less chemists, and by large, computationists. But first and foremost, we, quantum chemists, are conscious beings. We may safely guess that quantum chemistry was one of the first areas in the natural sciences to lie on the boundaries of many disciplines. We may certainly claim that quantum chemists were the first to use computers for really large scale calculations. The scope of the problems which quantum chemistry wishes to answer and which, by its unique nature, only quantum chemistry can only answer is growing daily. Retrospectively we may guess that many of those problems meet a daily need, or are say, technical in some sense. The rest are fundamental or conceptual. The daily life of most quantum chemists is usually filled with grasping the more or less technical problems. But it is at least as important to devote some time to the other kind of problems whose solution will open up new perspectives for both quantum chemistry itself and for the natural sciences in general. 264 pp. Englisch.

Thus, the primary object of the book is to present a simple exposition of Maxwell's theory, of General Relativity and of the link between those two concepts, namely, Special Relativity. In the nineteenth century the notion of a continuous field gradually replaced the idea of action at a distance. The electromagnetic theory that was elaborated at that time covers a very large area of Physics, since it makes possible the description of permanent phenomena, electrostatics and magnetostatics, as well as of variable phenomena. It anticipates the existence of waves, and thereby the theory of light is annexed to this vast domain. It was discovered that Maxwell's equations changed their form when they were related to reference systems associated with two observers in rectilinear uniform motion with respect to each other and each endowed with the absolute time required by classical mechanics. This was a most remarkable fact. Indeed, as soon as attempts were made to verify the results of classical kinematics by means of experiments with the propa gation of light, there arose a whole series of contradictions. 488 pp. Englisch.

The institute was organized by E. Haug and J. Cea, with the enthusiastic help of leading contributors to the field of distributed parameter structural optimization. The principle con tributor to this field during the past two decades, Professor William Prager, participated in planning for the Institute and helped to establish its technical direction. His death just prior to the Institute is a deep loss to the community of engineers and mathematicians in the field, to which he made pioneering contri butions. The proceedings are organized into seven parts, each address ing important problems and special considerations involving classes of structural optimization problems. The review paper presented first in the proceedings surveys contributions to the field, primarily during the decade 1970-1980. Part I of the pro ceedings addresses optimality criteria methods for analyzing and solving problems of distributed parameter structural optimization. Optimality criteria obtained using variational methods of mech anics, calculus of variation, optimal control theory, and abstract optimization theory are presented for numerous classes of struct ures; including beams, columns, plates, grids, shells, and arches. 864 pp. Englisch.

The main objective of this workshop was to provide a forum for the exchange of information and views on major issues relating to the fundamentals of character izing the inelastic constitutive material behavior. Comments on the Aims of the Workshop, by Drs. William Snowden and Thomas Bache, pp. 1-5, outline reasons for holding this workshop, and provide further background. The format of the workshop was designed to optimize the interaction between researchers whose primary interest is material characterization and numerical analysts whose primary interest is the development and practical use of large computer codes. The program of the workshop and a list of the workshop partic ipants are found at the end of these proceedings. 428 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Instead of the old division of the right angle in 90° of 60' at 60' each, the following division finds ever more frequent application: one quadrant has 100 grades (gr), which in their turn are sub divided decimally in decigrades (dgr), centigrades (cgr), milligrades (mgr) and decimilligrades (dmgr). In using instruments upon which the quadrant is divided into 100 equal parts, in working with a calculating machine or a slide rule the new division has all the advantages and the old system all the disadvantages. Another important advantage of the new system is that the arcs take their place in the decimal system. One fourth of a meridian of the earth is 10.000 km, also 100 X 100 cgr; hence one km equals 1 cgr of the circumference-of the earth. If the arc of a longitude gr then circle between two given points on the earth be 14,26 their distance measured along this arc is 1426 km. It further follows that 1 mgr of the meridian equals 1 hm and 1 dmgr 10 meters. This simple calculation shows that for use in schools we should confine ourselves to milligrades (1 mgr = 3',24). Experts have assured me that for most practical applications milligrades are sufficiently accurate. 180 pp. Englisch.

The second symposium was also held at Churchill College on 30-31 July, 1981, and this, the third, took place at the same college on 30-31 July, 1983. The meeting was structured in a format which we hoped would appeal to the full range of our membership. The philosophy of the ADG is that medical microbiologists, veterinarians, toxicologists and dental bacteriologists have much to learn from each other and can best be achieved by bringing these various disciplines together frequently and in informal surroundings. Again the symposium was very generously sponsored by May and Baker Limited who met all costs of the meeting and entertained us splendidly. David Jackson and Donald Bedford were re sponsible for coordinating with the ADG on behalf of May and Baker and, as usual, gave us their full cooperation. This book contains the full-length papers, followed by the posters presented at the meeting. This book also serves as a vehicle for the abstracts of the first meeting of the Society for Intestinal Microbial Ecology and Disease, SIMED, held in Boston, Massachusetts. An introduction to this new society by its President, Sydney M. Finegold, M.D., precedes the abstracts. M.J.

Yet much remains to be done if solar heating is to reach its full potential. The Conference Committee hopes that this record of the proceedings will provide a basis for the further development of these systems. Many difficulties have been surmounted in arriving at today's position. The foundations of the growing confidence of architects and engineers are to be found in the concerted programmes of research and development mounted by ty,'o of the sponsors of the Conference the European Community and the International Energy Agency. Some of the more tangible products of these programmes have been reported here: component and system behaviour has been subjected to rigorous scientific study; new test facilities have been founded; test procedures devised; simulation methods developed and evaluated; design rules formulated and checked against measured performance. It has been apparent here that the willingness to exchange information and experiences, which has always been a feature of the solar energy scene, remains as strong as ever. A further information-sharing initiative was noted on the part of another sponsor, UNESCO - the setting-up of the European Cooperative Network on Solar Energy, involving countries from both eastern and western Europe. 1088 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The theory of foliations and contact forms have experienced such great de velopment recently that it is natural they have implications in the field of mechanics. They form part of the framework of what Jean Dieudonne calls 'Elie Cartan's great theory ofthe Pfaffian systems', and which even nowa days is still far from being exhausted. The major reference work is. without any doubt that of Elie Cartan on Pfaffian systems with five variables. In it one discovers there the bases of an algebraic classification of these systems, their methods of reduction, and the highlighting ofthe first fundamental in variants. This work opens to us, even today, a colossal field of investigation and the mystery of a ternary form containing the differential invariants of the systems with five variables always deligthts anyone who wishes to find out about them. One of the goals of this memorandum is to present this work of Cartan - which was treated even more analytically by Goursat in its lectures on Pfaffian systems - in order to expound the classifications currently known. The theory offoliations and contact forms appear in the study ofcompletely integrable Pfaffian systems of rank one. In each of these situations there is a local model described either by Frobenius' theorem, or by Darboux' theorem. It is this type of theorem which it would be desirable to have for a non-integrable Pfaffian system which may also be of rank greater than one. 256 pp. Englisch.

The significance of that night marked one of the truly great turning points in the development of astronomical techniques: Dr Henry Draper, a wealthy New York medical doctor, had secured the first photograph of a nebula: a 51-minute exposure on a dry gelatinobromide plate showing the wispy nebulosity of the Orion Nebula. By March 1882, Draper had secured an exposure of 137 minutes, showing far richer detail of both bright and dark features. The rest is histapy. The photographic era heralded in a universe where hints of the presence of cosmic dust were strongly alluded to: from star-forming regions such as Messier 17, to the Horsehead Nebula in Orion, to the striking dark finger in the Cone Nebula, to the magnificent dark bands in the plane of our Milky Way.
