Patients m a y attend either medical or surgical clinics and n o t infrequently present as acute abdominal emergencies to general practitioners, physicians, surgeons and even gynaecologists. Recent urinary calculi continue to cause considerable morbidity despite the recent advances in our understanding of the pathogenesis of the different types of stones involved and despite improvements in t reatment- by appropriate drug therapy, by ultrasound techniques and by lithotripsy. This volume discusses the investigation and management o f patients with calculus disease. Each chapterhas been written by a n experienced clinician and provides information of considerable relevance and importance for all doctors engaged in clinical practice. The technical developments o f the last few years have clearly demonstrated that renal stone disease, even when recurrent, should be an uncommon cause of chronic renal failure. Knowledge o f the recent developments in this field is important for all practising doctors and even more important for their patients. 104 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -For more than a century, heterocycles have played a crucial role in the biological and industrial development of society, becoming one of the most researched areas within organic chemistry.The first chapter of Microwave-Induced Synthesis of Aromatic Heterocycles is based on microwave theory, the latest developments in instrumentation technology, and the various microwave technologies used for synthesis. The remainder of the chapters are divided into two sections. Section A deals with the five-membered heterocycles (pyrazoles, isoxazoles, triazoles, oxadiazoles, thiazoles, imidazoles, oxazoles, oxazolines etc.) and in Section B, various six-membered heterocycles (triazines, benzoxazoles, benzimidazoles, benzothiazoles) are presented. Both sections contain a detailed, recent literature review of microwave assisted synthesis and its applicability to various aromatic heterocyclics. 104 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -We first discussed the possibility of organizing a symposium on helminth communities in June, 1986. At that time, we were engaged in writing a joint paper on potential structuring mechanisms in helminth communities; we disagreed on a number of issues. We felt the reason for such debate was because the discipline was in a great state of flux, with many new concepts and approaches being introduced with increasing frequency. After consider able discussion about the need, scope and the inevitable limitations of such a symposium, we decided that the time was ripe to bring other ecologists, engaged in similar research, face-to-face. There were many individuals from whom to choose; we selected those who were actively publishing on helminth communities or those who had expertise in areas which we felt were particularly appropriate. We compiled a list of potential participants, contacted them and received unanimous support to organize such a symposium. Our intent was to cover several broad areas, fully recognizing that breadth negates depth (at least with a publisher's limitation on the number of pages). We felt it important to consider patterns amongst different kinds of hosts because this is where we had disagreed among ourselves. 352 pp. Englisch.

Among the key areas are polymer chemistry, as new binders are developed to meet increasingly stringent environmental demands; testing and evaluation, as the need to understand the factors affecting coatings performance becomes ever more intense; and studies of that enduring problem, corrosion of metal substrates, from which coatings of ever improving effectiveness are emerging. We have in this present volume of the series continued to cover aspects of these numerous developments. There are chapters on waterborne paint, a subject of increasing environmental importance, by J. W. Nicholson, and by H.-J. Streitberger and R. P. Osterloh; on a new and sophisticated test method, acoustic emission (R. D. Rawlings); and on anticorrosion coatings both organic (W. Funke) and inorganic (M. C. Andrade and A. Macias). Finally, that topic of immense practical importance to paint technology, pigmentation, is covered in a chapter by the late T. Entwistle. All the authors have brought considerable experience in their chosen field of coatings technology to the preparation of their chapters, all of which are timely reviews of developing topics. We are grateful to each author for helping in the preparation of this volume, and for putting their experience at the disposal of the wide audience for whom this book is intended. 244 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Bile acids occupy a central position in in the absorption, excretion and metab olism of lipids within the body. Our understanding of their unique properties has illuminated many biochemical and biophysical processes. Animals have evolved a unique system of preserving these important detergent-like molecules within the body and reusing them many times - the enterohepatic circulation. Disorders of the enterohepatic circulation contribute to a correspondingly wide range of diseases, and recent developments have centred in particular on cholesterol gallstone disease and bile acid diarrhoea. Successful manage ment of these diseases is increasingly based on an understanding of the physicochemical and biochemical properties of bile acids, and of their pathophysiological role in disease. Professor Alan Hofmann starts this book with an overview of the enterohepatic circulation of bile acids. The first section then discusses biliary lipid synthesis, transport and secretion by the liver and the solubilisation of cholesterol in the bile. The next section applies this knowledge to the pathogenesis of cholesterol gallstones. Separate chapters focus on defects in biliary lipid secretion, in cholesterol solubilisation and in gallbladder motility. The succeeding sections then review posssible approaches to gallstone prevention, and assess recent developments in non-surgical forms oftreatment. Two exciting new therapies that receive particular attention are contact dissolution therapy with methyl tert-butyl ether and extracorporeal shock wave lithotripsy. Further sections turn to the absorptive functions of bile acids in health. 328 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -These four volumes comprlslng 'GnRH Analogues in Cancer and Human Reproduction' are a distillation of the presentations of the invited speakers at a landmark International Symposium bearing the same name, organized by one of us (B. L. ) and held in Geneva, SwitLerland in February 1988. The Symposium was truly interdisciplinary spanning gonadal hormone dependent disease including various forms of cancer and ranging to control of fertility, both pro- and conception. The international flavor can be caught from the 480 participants and 259 contributors drawn from 14 countries. The Symposium, and therefore this book, would not have been possible without the backing of The International Commitlee for Research in Reproduction and the sponsorship of the International Society of Gynecologic Endocrinology, The Swiss Society of fertility and Sterility, The University of Geneva School of Medicine, The Swiss Society of Endocrinology and The US foundation for Studies in Reproduction Inc. , and help from the World Health Organization.

This item is printed on demand - it takes 3-4 days longer - Neuware -The workshop reported in this volume is one of a series sponsored by the Commission of the European Communities, Directorate-General for Science, Research and Development (DG XII), under the Concerted Action Programme COST 84-bis, entitled 'Use of lignocellulose containing by-products and other plant residues for animal feeding'. Since COST 84-bis was established there has been a major shift of emphasis in agricultural research in Europe, with the development of alternative uses for crops and their by-products becoming a priority issue. In recognition of this recent workshops he,ld under the aegis of COST 84-bis have been equally concerned with the potential of lignocellulosic residues to form the feedstock for a variety of new and established industrial uses in addition to their established use as animal feed. Development of strategies for the use of plants or plant residues with a high cell wall content is dependant on knowledge of cell wall structure and organisation and how structure relates to the behaviour of the wall during mechanical, chemical or biological processing. Progress in cell wall research has been greatly facilitated by the substantial developments in methods of instrumental analysis that have occurred during the last decade. Plant tissues now can be examined in far greater detail and far more rapidly than was hitherto possible, often without the need for extraction or modification of the cell wall or its component polymers. 180 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The field of surface coatings is now so extensive, and is developing so rapidly, that no individual person could be expected to master it in its entirety. Hence, the days have gone when a lone author could compile a comprehensive treatise on the topic without overlooking many of the most significant developments. Yet the very growth and diversity of surface coatings make it essential that workers in the field should have access to up-to-date and authoritative reviews. It is to satisfy this need that we have assembled our team of authors, each of whom is an expert in his or her branch of the subject, and is well able to as'sess w:hat is most significant and exciting within that branch. They h,ave b~en encouraged to develop their themes in what they have felt to be the most appropriate way, with minimal editorial interference from us. We believe that the results of their labours will be of benefit to those engaged not only in basic research, but also to those working ip product development and in testing and evaluation of coatings. 288 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Strictly speaking, the term regulatory peptides may include any peptide which has a regulatory function in any organism. In recent years, how ever, the term has come to mean those originally classified as brain-gut peptides. The peptides initially defined as those belonging to the brain gut axis had a dual location in neurones of the brain and endocrine cells of the gut. We now include a number of neuropeptides found in the autonomic nervous system of the gut, the cardiovascular system and other systems. To many scientists comparative physiology means comparison of the mechanisms of certain functions in the rat, the guinea-pig, the cat and maybe some other mammal. If the philosophy is that man is the centre of the universe and other mammals can be used as 'models' of man, this may well be the most useful way to study the functions of the human being, without actually chopping somebody up. However, with a some what wider perspective on life, it is easy to see the importance of a full understanding of the function of all living organisms, in its own right as well as a link in the evolution towards individuals able to survive and reproduce in very different environments. The importance of com parative studies in all living organisms cannot be emphasized too much. It has been the ambition with this book to treat all animals as equally important. 396 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -These proceedings include tutorials and papers presented at the Sixth CSR Confer ence on the topic of Large Software Systems. The aim of the Conference was to identify solutions to the problems of developing and maintaining large software systems, based on approaches which are currently being undertaken by software practitioners. These proceedings are intended to make these solutions more widely available to the software industry. The papers from software practitioners describe: - important working systems, highlighting their problems and successes; - techniques for large system development and maintenance, including project management, quality management, incremental delivery, system security, in dependent V & V, and reverse engineering. In addition, academic and industrial researchers discuss the practical impact of current research in formal methods, object-oriented design and advanced environ ments. The keynote paper is provided by Professor Brian Warboys of ICL and the University of Manchester, who masterminded the development of the ICL VME Operating System, and the production of the first database-driven software en gineering environment (CADES). The proceedings commence with reports of the two tutorial sessions which preceded the conference: - Professor Keith Bennett of the Centre for Software Maintenance at Durham University on Software Maintenance; - Professor John McDermid of the University of York on Systems Engineering Environments for High Integrity Systems. The remaining papers deal with reports on existing systems (starting with Professor Warboys' keynote paper), approaches to large systems development, methods for large systems maintenance and the expected impact of current research. 388 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The Materials Research Society of Japan (MRS-Japan), formerly the Advanced Materials Science and Engineering Society (AMSES), was established on 16 March 1989 in Tokyo, Japan. AMSES was established following the International Conference on Advanced Materials, held from 30 May to 3 June 1988 in Tokyo (MRS Bulletin, October and November 1988). This meeting was similar to the MRS meeting held in Boston, USA, and consisted of 21 symposia, which were published as proceedings in 14 volumes. The number of participants was over 1600. The first President of AMSES, Professor Masao Doyama, gave the following address: As advanced technology develops toward its highest goals, a small improvement in existing materials is not enough to meet the demands. The deadlock of advanced technology often brings the invention of new materials. Human civilization has grown along with materials. The Stone Age, the Bronze Age, and the Iron Age represent the materials most used in those times. Since the beginning of the 20th century, the plastic age, the semiconductor age, the new ceramics age, and the composite materials age have been identified, but no single material dominates. 476 pp. Englisch.

This was the fifth symposium organised by the Electro chemical Technology Group of the Society of Chemical Industry and proved as popular as ever, attracting a record number of 294 delegates from 31 countries. Twenty-seven papers were presented during the two and a half-day event covering the latest developments in chlor-alkali technology. The field of membranes and membrane cells was well represented by some 15 papers, reflecting the importance of membrane technology to the future of the industry. This is particularly relevant in view of increasing environmental pressures and rising costs. However, papers relating to the more traditional mercury and diaphragm cell technologies were also presented, together with a paper concerned with sodium chlorate manufacture. In addition, there were presentations covering the commercial and safety aspects of the chlor-alkali industry. The Electrochemical Technology Group of the Society of Chemical Industry offer thanks to the many people and organisations whose help ensured the success of this symposium. In particular, we would like to thank: 1. The contributors of the papers. 2. The session chairmen: Dr R. G. Smerko (The Chlorine Institute Inc.); Mr B.

The contribution to care by the urologist and the gynaecologist each with an interest in infertility is different but complementary. My appreciation of this was sharpened between 1976 and 1985 during my association with the World Health Organization's Spe cial Programme of Research Development and Research Training in Human Reproduction at the meetings of the Steering Committee of its Task Force on Infertility. The deliberations of this group were aimed at developing a protocol for investigation of the infertile couple and it became apparent to me as a gynaecologist how important is the precise characterization of the male partner's role to the formulation of the management plan for the infertile couple. To improve the quality of our evaluation of the male partner our techni cal staff were trained in the semen methodology of the laboratory of Dr F Com haire of Ghent and we were joined by Dr CLR Barratt, male reproductive biologist. It seemed appropriate to share our enthusiasm for clinical andrology, so after discussion with Dr Comhaire and Professor T Glover, an eminent male reproductive biologist, then of Brisbane, who planned a sabbatical to his native was arranged for 1 and 2 May 1986.

This item is printed on demand - it takes 3-4 days longer - Neuware -The NATO Advanced Study Institute on 'Algorithms for continuous optimiza tion: the state of the art' was held September 5-18, 1993, at II Ciocco, Barga, Italy. It was attended by 75 students (among them many well known specialists in optimiza tion) from the following countries: Belgium, Brasil, Canada, China, Czech Republic, France, Germany, Greece, Hungary, Italy, Poland, Portugal, Rumania, Spain, Turkey, UK, USA, Venezuela. The lectures were given by 17 well known specialists in the field, from Brasil, China, Germany, Italy, Portugal, Russia, Sweden, UK, USA. Solving continuous optimization problems is a fundamental task in computational mathematics for applications in areas of engineering, economics, chemistry, biology and so on. Most real problems are nonlinear and can be of quite large size. Devel oping efficient algorithms for continuous optimization has been an important field of research in the last 30 years, with much additional impetus provided in the last decade by the availability of very fast and parallel computers. Techniques, like the simplex method, that were already considered fully developed thirty years ago have been thoroughly revised and enormously improved. The aim of this ASI was to present the state of the art in this field. While not all important aspects could be covered in the fifty hours of lectures (for instance multiob jective optimization had to be skipped), we believe that most important topics were presented, many of them by scientists who greatly contributed to their development. 584 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Humans interact with and are part of the mysterious processes of nature. Inevitably they have to discover how to manage the environment for their long-term survival and benefit. To do this successfully means learning something about the dynamics of natural processes, and then using the knowledge to work with the forces of nature for some desired outcome. These are intriguing and challenging tasks. This book describes a technique which has much to offer in attempting to achieve the latter task. A knowledge of dynamic programming is useful for anyone interested in the optimal management of agricultural and natural resources for two reasons. First, resource management problems are often problems of dynamic optimization. The dynamic programming approach offers insights into the economics of dynamic optimization which can be explained much more simply than can other approaches. Conditions for the optimal management of a resource can be derived using the logic of dynamic programming, taking as a starting point the usual economic definition of the value of a resource which is optimally managed through time. This is set out in Chapter I for a general resource problem with the minimum of mathematics. The results are related to the discrete maximum principle of control theory. In subsequent chapters dynamic programming arguments are used to derive optimality conditions for particular resources. 364 pp. Englisch.

When we have an idea or thought about the world and we wish to express that idea or thought to others we utter a sentence or make a statement. If the statement correctly describes the world then it is true. Moreover, it seems as though our ability to have more complex or sophisticated thoughts about the world increases as the complexity of our language or our ability to use the language increases. Understanding the complex relationship between language, thought, and the world is one of the central aims of philosophy. This book is an attempt to increase our understanding of this complex relationship by focusing on certain philosophical issues that arise from our ability to refer to objects in the world though the use of language. In particular, it is an attempt to solve the puzzles of reference and belief that Frege and Russell presented within the context of a theory of direct reference for proper names. 232 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Remote sensing using aircraft and satellites has helped to open up to intensified scientific scrutiny the cold and remote regions in which snow and ice are prevalent. In this book, the utility of remote sensing for identifying, mapping and analyzing surface and subsurface properties of worldwide ice and snow features is described. Emphasis is placed on the use of remote sensing for developing an improved understanding of the physical properties of ice and snow and understanding the interrelationships of cryospheric processes with atmospheric, hydrospheric and oceanic processes. Current and potential applications of remotely sensed data are also stressed. At present, all-weather, day and night observations of the polar regions can be obtained from sensors operating in different portions of the electromagnetic spectrum. Because the approaches for analysis of remotely sensed data are not straightforward, Chapter 1 serves to introduce the reader to some of the optical, thermal and electrical properties of ice and snow as they pertain to remote sensing. In Chapter 2 we briefly describe many of the sensors and platforms that are referred to in the rest of the book. The remaining chapters deal with remote sensing of the seasonal snow cover, lake and river ice, permafrost, glacier ice and sea ice. 212 pp. Englisch.

In spite of developing new polymers and polymeric materials, only 40-60 are used commercially on a large scale. It has been estimated that half of the annual production of polymers is employed outdoors. Increasing the stability of polymers and plastics towards heat, light, atmospheric oxygen and other environmental agents and weathering conditions has always been a very important problem. The photochemical instability of most of polymers limits them to outdoor application, where they are photo degraded fast over periods ranging from months to a few years. To the despair of technologists and consumers alike, photodegrada tion and environmental ageing of polymers occur much faster than can be expected from knowledge collected in laboratories. In many cases, improved methods of preparation and purification of both monomers and polymers yield products of better quality and higher resistance to heat and light. However, without stabilization of polymers by applica tion of antioxidants (to decrease thermal oxidative degradation) and photostabilizers (to decrease photo-oxidative degradation) it would be impossible to employ polymers and plastics in everyday use. 612 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The Latin texts collected by Leon Baudry present the late fifteenth century debate at the University of Louvain over the truth-value of proposi tions about future contingent events, a subject of perennial interest in phil osophy. The theologians held fast to divine predetermination, and the Aristotelians in the Arts Faculty supported the doctrine of free choice based on indeterminism. Although the issues in the debate are still argued in philosophy, this rich collection of the theories and arguments has been neglected. Peter de Rivo and Henry de Zomeren, the principal antagonists, are cited in the recent literature, but only on the basis of slight, mostly second-hand information. The full collection of texts has never before been translated into English (or any other modern language), leaving them inaccessible to the majority of students, or any others who are not equipped to work their way through 450 pages of fifteenth-century scholastic Latin. Apart from their philosophical significance, the texts shed light on late scholastic methods in teaching and disputation, on university politics of the period in relation to the Vatican, the Court of the Duke of Burgundy, and the faculties of other great universities, and on legal procedures both secular and ecclesiastical. The human drama that develops as the debate proceeds should hold the interest of even the non-specialist. 472 pp. Englisch.

They came from 30 countries. The conference brought together two traditions. Firstly, it continued the series on Computer Applications in Fermentation Technology (ICCAFT) inaugurated by Henri Blanchere in Dijon in 1973 and carried forward in Philadelphia and Manchester. Secondly, it brought the expertise of the many members of the International Federation of Automatic Control (IFAC), who focused their attention on biotechnology at Noordwijkerhout in the Netherlands in December, 1985. I am happy to say that the tradition carries on and a successor meeting will hopefully take place in the USA in 1991. If you find these proceedings useful or stimulating, then we hope to see you there. We set out to make ICCAFT4 a close-knit friendly conference. We housed all who cared to in Robinson College itself and organised no parallel sessions. Because we, the organisers, experience difficulty with the jargon of our colleagues from other disciplines, we asked Bruce Beck to present a breakfast tutorial on modern control and modelling techniques, and we set up informal panel discussions after dinner on two evenings. Neville Fish chaired a forum on the microbiological principles behind models, while Professors Derek Linkens and Ron Leigh led a discussion on expert systems in control. 496 pp. Englisch.

Yet we rarely teach elementary and secondary students about these exposures and how they can reduce their risk to them. In this book we highlight activities and curriculum developed at nine universities in the United States from a grant funded by the National Institute of Environmental Health Sciences. Our goal is to extend these lessons to a global audience and for classroom teachers of all subjects and age levels to include environmental health in their teaching. 'An invaluable tool for equipping informed citizens to think about the environment and its human impacts --both the science, and equally important, the social and ethical dimensions' , Howard Frumkin, M.D., Dr. P.H., Dean, School of Public Health, University of Washington, Seattle, WA, USA 108 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume contains the Proceedings of the NATO Advanced Study Institute on 'Orthogonal Polynomials and Their Applications' held at The Ohio State University in Columbus, Ohio, U.S.A. between May 22,1989 and June 3,1989. The Advanced Study Institute primarily concentrated on those aspects of the theory and practice of orthogonal polynomials which surfaced in the past decade when the theory of orthogonal polynomials started to experience an unparalleled growth. This progress started with Richard Askey's Regional Confer ence Lectures on 'Orthogonal Polynomials and Special Functions' in 1975, and subsequent discoveries led to a substantial revaluation of one's perceptions as to the nature of orthogonal polynomials and their applicability. The recent popularity of orthogonal polynomials is only partially due to Louis de Branges's solution of the Bieberbach conjecture which uses an inequality of Askey and Gasper on Jacobi polynomials. The main reason lies in their wide applicability in areas such as Pade approximations, continued fractions, Tauberian theorems, numerical analysis, probability theory, mathematical statistics, scattering theory, nuclear physics, solid state physics, digital signal processing, electrical engineering, theoretical chemistry and so forth. This was emphasized and convincingly demonstrated during the presentations by both the principal speakers and the invited special lecturers. The main subjects of our Advanced Study Institute included complex orthogonal polynomials, signal processing, the recursion method, combinatorial interpretations of orthogonal polynomials, computational problems, potential theory, Pade approximations, Julia sets, special functions, quantum groups, weighted approximations, orthogonal polynomials associated with root systems, matrix orthogonal polynomials, operator theory and group representations. 488 pp. Englisch.
