Taschenbuch. Condición: Neu. Neuware -Following the development of gray-scale imaging, real-time scanning, Doppler examination, and high-frequency sonography, endosonography is one of the latest major breakthroughs in the history of diagnostic ultrasound. Although early attempts at inserting ultrasound transducers in natural cavities of the body can be traced back more than two decades, only in the past few years has technology allowed the development and commercialization of effective, easy-to-use endosono scopic probes. Because the transducer can be placed in direct contact with or close to lesions, high frequencies (up to ~2 MHz) can be used, yielding cross-sectional images of unsurpassed resolution. The availability of specially designed intracorporeal probes for specific natural cavities that are routinely explored by conventional (optical) endoscopy or palpation has significantly expanded the diagnostic applications of sonography. Transrectal and transvaginal examinations are now performed routinely in many institutions, and virtually all sonographic equipment manufac turers have in their line of products at least one endorectal and one endovaginal transducer. Most endosonoscopic probes connect to existing scanners, and for radiology departments, the invest ment for transrectal or transvaginal scanning will usually be limited to the purchase of the specific probe. In this book, clinical applications of endosonography (excluding transesophageal echocardio graphy) are covered by European and North American experts. Current equipment and techniques of examination are described in detail to help newcomers get started in the field of endosonography. 200 pp. Englisch.…

Taschenbuch. Condición: Neu. Neuware -The thirty-five chapters in this book are edited versions of papers presented at the Advanced Research Workshop, State Intervention on Behalf of Children and Youth, which took place in Maratea, Italy, February 20-24, 1989. The Workshop was attended by leading child welfare researchers from most of the Western countries. Represented were scholars and practitioners from disciplines as diverse as law, social work, neurology, economics, political science, education, psychology, and psychiatry. This variety of disciplines considerably enriched the discussions at the Workshop and is reflected in a set of interesting and, we believe, potentially useful research papers. This book is divided into four sections, each dealing with dominant themes of state intervention. The first section deals with research on organizing for state intervention and related ways of providing accountability. The second section deals with research on young persons in conflict with the law, the third with research on child abuse and the final section with research on children in care. Many of the matters addressed in these papers relate to more than one of the topical theme headings and, therefore, might well have been located in different sections of the volume. Each section is introduced by an introductory statement that provides an overview of the papers and issues addressed, and suggests an agenda of research work to be undertaken. These introductions are based largely on workshop discussions and do not necessarily represent the views of their identified authors.…

Taschenbuch. Condición: Neu. Neuware -The farming of deer as an alternative to traditional livestock enterprises is now firmly established and is expanding within several countries of the European Economic Community. However, the successful farming of deer requires the adoption of appropriate management schemes to accommodate the biological requirements of these animals. Much experience has now been gained and it is essential that this information becomes readily available througout the Community. In addition, as the volume of deer farming has increased a number of health problems have become recognised which present features distinct from other domestic ruminants. Although knowledge is still incomplete it would appear that deer may react to certain pathogens in a very different way to other domestic ruminants, presenting new problems of diagnosis and control. The rapid detection of these conditions and development of appropriate control strategies will be essential for the establishment of an economically viable deer farming industry in the Community. Much of the information on the management of farmed deer and their diseases is anecdotal and fragmented and the purpose of this meeting was to accelerate the dissemination of this knowledge between scientists in the Community committed to the development of this area of agricultural industry. The meeting, financed by the Commission of the European Communities from its budget for the Coordination of Agricultural Research in the Community was held in Scotland, on the 10th to 11th December, 1987.…

Taschenbuch. Condición: Neu. Neuware -Until the early seventies, tautomeric i. e. fast and reversible rearrangement reactions accompanied by migrations of carbon-centered groups - were practi cally unknown. For a long time it was assumed that the family of tautomeric reactions was confined to proto tropic transformations only. However, the discovery in the fifties of the reversible metallotropic rearrangements showed the domain of migratory tautomerism to be substantially broader. The synthesis of the metallotropic compounds was based on the substitution of a proton in prototropic compounds by an organometallic group. This approach rarely proved fruitful when attempting to effect tautomeric rearrangements of organic and organometallic groups formed by the elements to the right of carbon in the Periodic Table. By contrast, a novel approach involving an analysis of the steric requirements inherent in the structure of the transition state of a reactive center and an examination of the stereodynamic possibilities has given rise to a target-oriented molecular design of compounds capable of rapid and reversible intramolecular migration of the type indicated. The implementation of this ap proach, which is the subject of the present book, has already led to the preparation of new tautomeric compounds in which such heavy organic migrants as acyl, aryl, sulfinyl, phosphoryl, arsinyl, and other groups migrate in molecules at a frequency 6 9 of 10 -10 S-I at ambient temperature, i. e. , at the rates comparable with protonic migrations.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This compact volume is meant as a modest contribution to the ongoing debate on how to transform in particular the radically reforming Eastern European economies into more productive sociopolitical organizations. Although my main focus here is on the economics of reform and east-west assistance, I have tried to embed the multiple technical aspects of restructuring such a resource alloca tion into the context of remaking Eastern Europe. That the volume coincides with the seminal transformations of the communist countries of Eastern Europe is, of course, not fortuitous. But I shall have much less to say about the politi cal transitions from communism to parliamentary democracy, except the ways in which the latter may bolster or hinder the hoped-for economic mutations. In taking stock of where I stand on the issue of 'radical reform' of planned economics in general and the CMEA in particular, both still moving targets, I have benefited greatly from participation in formal and informal conferences on economic reform. The product has also profited from many informal discus sions and exchanges of views among friends and colleagues, including those entrusted with and purely interested in efforts on the overall topic of the study launched from within the broad context of the United Nations, my at times reluctant employer. 240 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -For many years it has been recognized that engineering materials that are-tough and ductile can be rendered susceptible to premature fracture through their reaction with the environment. Over 100 years ago, Reynolds associated hydrogen with detrimental effects on the ductility of iron. The 'season cracking' of brass has been a known problem for dec ades, but the mechanisms for this stress-corrosion process are only today being elucidated. In more recent times, the mechanical properties of most engineering materials have been shown to be adversely affected by hydrogen embrittlement or stress-corrosion cracking. Early studies of environmental effects on crack growth attempted to identify a unified theory to explain the crack growth behavior of groups of materials in a variety of environments. It is currently understood that there are numerous stress-corrosion processes some of which may be common to several materials, but that the crack growth behavior of a given material is dependent on microstructure, microchemistry, mechanics, surface chemistry, and solution chemistry. Although the mechanism by which various chemical species in the environment may cause cracks to propagate in some materials but not in others is very complex, the net result of all environmentally induced fracture is the reduction in the force and energy associated with the tensile or shear separation of atoms at the crack tip. 748 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Gas at temperatures exceeding one million degrees is common in the Universe. Indeed it is likely that most of the gas in the Universe exists in intergalactic space in this form. Such highly-ionized gas, or plasma, is not restricted to the rarefied densities of intergalactic space, but is also found in clusters of galaxies, in galaxies themselves, in the expanding remnants of exploded stars and at higher densities in stars and the collapsed remains of stars up to the highest densities known, which occur in neutron stars. The abundant lower-Z elements, at least, in such gas are completely ionized and the gas acts as a highly conducting plasma. It is therefore subject to many cooperative phenomena, which are often complicated and ill-understood. Many of these processes are, however, well-studied (if not so well-understood) in laboratory plasmas and in the near environment of the Earth. Astronomers therefore have much to learn from plasma physicists working on laboratory and space plasmas and the parameter range studied by the plasma physicists might in turn be broadened by contact with astronomers. With that in mind, a NATO Advanced Research Workshop on Physical Processes in Hot Cosmic Plasmas was organized and took place in the Eolian Hotel, Vulcano, Italy on May 29 to June 2 1989. This book contains the Proceedings of that Workshop. 464 pp. Englisch. …

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Infertility is a problem for the couple and evaluation of the couple is preferable in a clinic where both males and females may be seen together. 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.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -One of the most interesting results obtained in the last two decades in the study of crustal deformation has been the recognition that large regions of continental crust undergo rotations about vertical axis during deformation. Proof of such rotations has come through the paleomagnetic studies, which reveal rotations when paleomagnetic declinations within the deforming region arc compared with those found in coeval rocks in the stable regions outside the deforming zone. Such rotations were first described in Oregon then in the North American Cordilleras and in Southern California and were a surprise to everyone. Even in California which, as a result of oil exploration, was among the best geologically explored regions in the world, no one could claim to have predicted that these rotations would be found. Rotations have subsequently been found in other areas of recent continental tectonic activity, notably in the Basin and Range province, New Zealand, the Andes, Greece and Western Turkey, so that they appear as an important feature of continental deformation. 536 pp. Englisch.…

Professors Dennis Sciama and Fabio Mardirossian and all the other Members of the Organizing Committees are to be congratulated for having given us a taste of this excitement in Trieste, by inviting the leaders of the subject to the meeting they have organized. The excitement has corne from the new observations of the three-dimensional structure of the universe through a large number of new measurements of redshifts. These have revealed that clusters of galaxies are distributed on the surface of big empty bubbles of diameters of the order of 20-50 Mpc. Additionally, there is some evidence for invisible dark matter (whose composition is not known) as well as evidence for the gravitational lens effect. To cap this has corne the supernova of 1987, an event which last occurred 383 years ago. For the first time in history, the neutrino flux from the supernova was measured, giving limits to neutrino masses and numbers of neutrino types. (The dark matter problem is related to Particle Physics - beyond this standard model). It is good to be alive when all this happens and to try to comprehend this. Once again, our appreciation to the organisers and to those who presented their beautiful results. 512 pp. Englisch.…

As such, it offers a wealth of information, available here for the first time to interested parties around the world. Because the National Institutes of Health was quick to see the potential of CAPO as a promising therapy for patients with end stage renal disease, the Registry project was begun soon after its introduction into clinical practice in the USA. Accordingly, the Registry offered the nephrology community in the United States a special opportunity to study this emerging new therapy in some detail, an opportunity not previously available for any other form of dialysis. As will be seen in this report, the result of this early and intensive research effort has been the development of a vast amount of clinically important information regarding the utilization, safety, and efficacy of this important dialytic therapy. 324 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume is published with a triple aim: to take a look back over the advances during the ten years of the Mediterranean Burns Club and mark its anniversary; to follow up and strengthen the successful twin ning of burns as a clinical, individual illness problem and fires as a societal, disaster management problem; and to look ahead at the per spectives of burn care and fire prevention in the fast-approaching new century. The occasion also marks the tenth annual presentation of the prestigious G. Whitaker International Burns Prize, to which the Mediterranean Burns Club acts as the scientific fulcrum. The award is now established as the most distinguished recognition in burns science worldwide, and it is gratifying that the contributions of many of the renowned recipients will be found in this book. This is a sequel to The Management of Mass Burn Casualties and Fire Disasters, which contained the Proceedings of the First International Conference on Burns and Fire Disasters. The book and the conference have fully justified the authors' initial concept that burn specialists, con stantly combatting burn disease and promoting rehabilitation of the victims, especially in mass casualty situations, had for too long remained separate from that other essential sector, the fire-fighting authorities and fire prevention systems, whose aim is also the protection of the individual and the promotion of safety. This long overdue synergism has now become reality, and the present volume strengthens this desirable trend. 624 pp. Englisch.…

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -At present we may be at the cross-roads in the therapeutic approaches we have for the treatment of the 100 or more rheumatic conditions. This is be cause we now recognise that although some advances have been made with the development of a large range of non-steroidal and steroidal drugs during the past two decades or so, we now recognise that many, if not all, of these have rather limited effects on many of the disease processes which underlie the manifestations of the various rheumatic states. Advances in molecular bi- 010gy in the past 5-10 years have enabled these tools to be applied extensive ly for developing further our understanding of the rheumatic disease processes. In some cases these molecular tools (e. g. ,),-interferon, interleukin- 2, T-cell antibodies) have been directly employed as therapies themselves. While the outcome from trials with such agents in rheumatoid arthritis in particular has not been as would have been hoped, these results as with cy closporin A and low-dose methotrexate in the therapy of rheumatoid arth ritis have given us important indications for the approach employing what are generally described as 'immunomodulators' to control this disease. But this may not be the same type of approach which is desirable for all types of rheumatic conditions. Indeed, even the way which the present range of drugs and other therapies are applied may not be the most effective and safe means of treating different types of arthritic conditions. 340 pp. Englisch.…

The Twelfth Symposium in this series focused on the unifying biochemical and physiological mechan isms controlling growth and development of biological systems - ani mals, plants insects. Unraveling the complex biochemical mechanisms associated with the sequencing of organism growth and development and identifying, locating, and manipulating key control mechanisms are essential in utilizing the full potential of biotechnology for improving the composition and quality of agricultural products and the profitability of agriculture. Accordingly, speakers directed their remarks to basic aspects of biological mechanisms in their area of specialization with considera tion given to current status, future direction, potential impact, and limitations to progress. The Symposium addressed fundamental questions in: -Tissue specific gene regulation: cell division and differentiation -Mechanisms for regulating hormone concentration -Hormonal regulation of growth and development -Non-hormonal regulation of growth and development -Nutritional regulation of growth and development Because the backgrounds of the symposium attendees covered a wide spectrum in the basic biological and physical sciences, each topic was introduced by a brief overview, but general reviews were avoided in favor of findings from on-going research projects. The symposium brought together a distinguished group of invited scientists from around the world who are leaders.

Ten years later, the Fifth European Symposium on Physico-Chemical Behaviour of Atmospheric Pollutants, organized as for the previous Symposia In the framework of the Concerted Action \*COST 611, was held in Varese (Italy) from 25 to 28 September 1989. This Volume contains the oral papers and the posters presented at this Symposium. Participation at this Conference Is more than doubled of that In 1979 In terms of scientists (185) and contributed papers (110). This simple comparison demonstrates once more the growing attention of the scientific community to the problems related to the pollution of the atmosphere. During these years, Important new Issues have arisen (global pol lutlon/cl Imatlc changes) whl Ie old ones have been reviewed due to new experimental evidence (depletion of stratospheric ozone). The Symposium offered the best opportunity for a review of the current studies and technical progress achieved In the various sectors of the Concerted Action since the Fourth Symposium held In Stresa (Italy) In September 1986. In 1987 the scientific programme and the operational structures of the COST 611 Project were revised. The Project Is now structured into three Working Parties: 1.

Like any other branch of applied economics, it has drawn its tools and techniques from the wide range already available in economics gener ally, selecting, adapting and extending these to meet its own particular requirements in its own particular context. Here, as elsewhere in economics, public policy analy sis requires quantitative assessments of the economic impact of different policy choices. Perhaps the most distinctive contribution of environmental economics has been the development of techniques for the economic valuation of environmental goods and services in the absence of markets for such goods and services, or in the presence of markets that are at best imperfect or incomplete. Nevertheless policy analysis still relies on one or another of three broad groups of methods used in eco nomics generally. One is project appraisal, which at the micro level provides an evaluation ofthe costs and benefits ofinvestment options to inform the choice among them, while at the macro level policy analysis rests either on computable general equilibrium (CGE) models or on economy-wide macroeconometric models. All models are simplifications, designed to focus attention on the important fea tures ofthe problem at hand, and neglecting other features that might for a different problem assume greater importance. 184 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -What determines the number of political parties in a democracy Electoral rules certainly influence the incentives to create and maintain parties. However, a society's political culture can maintain parties despite electoral rules that give them poor prospects of success. Thus, comparing the number of parties and differences in electoral rules across countries cannot clearly test the effect of the electoral rules. A better test would examine a society with a fairly continuous political culture, but a change in electoral rules. Postwar France is such a society. While the basic social order has not changed, there was a drastic change in the electoral system in 1958, which theory implies would reduce the number of parties. Thus we can test the hypothesis that the number of parties fell with the change in electoral system. We can also calculate an ' equivalent number of parties to see how closely France approached a two - party system under the new regime. The first section describes the electoral rules under the Fourth and Fifth Republics. The second section develops a model that indicates how the change in electoral rules should have affected the incentives for multiple parties. The third section tests the hypothesis that the number of parties fell from the Fourth to the Fifth Republic. 1. Electoral Rules In the French Fourth Republic (1945 - 1958) political parties existed largely to serve the direct interests of their members. 452 pp. Englisch.…

The Society issupported byalargenumberofcentralbanksandcommer cial banks, byother financial and business institutions, by treasury officials and by academics and others interested in monetary and financial prob lems. Since its establishment in 1963 it has developed as a forum for the exchange of information, research results and ideas, valued by academics and practitioners in these fields, including central bank officials and civil servants responsible for formulating and applying monetary and financial policies, national and international. A major 'activity of SUERF is to organize and conduct Colloquia on subjects of topical interest to its mem bers. The titles, places and dates of previous Colloquia for which volumes of the collected papers were published are noted on the last page of this volume. Volumes were not produced for Colloquia held at Tarragona, Spain in October 1970 under the title 'Monetary Policy and New Develop ments inBanking'andatStrasbourg, France inJanuary 1972underthe title 'Aspects ofEuropean Monetary Union'.

In these last years a great improvement of the general knowledge of the problem has been possible due to the increase, in number and quality, of observations and of the laboratory efforts to simulate 'cosmic' dust. Theoreticians have also given their contribution in solving some questions and in posing others. Continuing an effort started in 1987, the Astrophysical Groups operating in Naples th th have considered it useful to organize a Workshop in Capri from September 8 to 13 1989 in order to assess the state of the art in such an interesting field as that of 'Dusty Objects in the Universe'. The subject is, obviously, too wide to be discussed in detail. However, the presence of many experts in different areas provided an updated general picture. Laboratory work has been reviewed, as well as recent observations and theoretical interpretations which concern processes occurring in our Galaxy and in external galaxies. The Workshop gave to participants the unique opportunity of exchanging ideas and of discussing on different themes. In addition, the meeting has been enriched by the presentation of the major technological projects related to ongoing airborne and space mlSSlons. the aim of giving the state of the art about specific Invited papers were prepared with subjects; contributed papers and some selected poster papers presented, on the contrary, the various fields. 300 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -User-adaptive (or 'personalized') systems take individual character istics of their current users into account and adapt their behavior ac cordingly. Several empirical studies demonstrate their benefits in areas like education and training, online help for complex software, dynamic information delivery, provision of computer access to people with dis abilities, and to some extent information retrieval. Recently, personal ized systems have also started to appear on the World Wide Web where they are primarily used for customer relationship management. The aim hereby is to provide value to customers by serving them as individuals and by offering them a unique personal relationship with the business. Studies show that web visitors indeed spend considerably more time at personalized than at regular portals and view considerably more web pages. Personalized sites in general also draw more visitors and turn more visitors into buyers. Personalization therefore would look like a win-win technology for both consumers and online businesses. However, it has a major down side: in order to be able to exhibit personalized behavior, user-adaptive systems have to collect considerable amounts of personal data and 'lay them in stock' for possible future usage. Moreover, the collection of information about the user is often performed in a relatively inconspic uous manner (such as by monitoring users' web navigation behavior), in order not to distract users from their tasks. 236 pp. Englisch.…
