This item is printed on demand - it takes 3-4 days longer - Neuware -The two essays provide a critical examination of theory and research in the field of evolutionary psychology. The view advanced here is that philosophical materialism and minimalist assumptions about adaptation serve Darwinian psychology better than the more popular alternative view that relies on cognitive dualism and propositional-attitude psychology to formulate evolutionary psychology theory. A commitment to cognitive dualism is destined to undermine the physical basis of behavior upon which evolutionary theory depends. Many evolutionary psychologists do not see this but are seduced by the easy way in which hypotheses can be formulated using the 'propositional-attitude' model. The challenge is to develop a materialistic and mechanistic approach to understanding human cognition and behavior, including linguistic and social behavior. 100 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book examines the discourse surrounding the wireless, created by the Anglo-Italian inventor Guglielmo Marconi. The wireless excited early twentieth-century audiences before it even became a viable black box technology. The wireless adhered to modernist values-speed, efficiency, militarization, and progress. Language surrounding the wireless is a form of technical communication, overlooked by today's practitioners. This book establishes a broader definition for technical communication by examining a selection of the discourse surrounding Marconi's wireless. The book's main themes are the following: 1) technical communication is all discourse surrounding technology, 2) the field of technical communication (or technical writing) should incorporate analyses of discourse surrounding technologies into its epistemology, 3) the wireless is a product of the society from which it comes (early twentieth-century Western civilization), and 4) the discourse surrounding the wireless is infused with tropes of progress-speed, efficiency, evolution, and ahistoricity. 168 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -There is a wide variety of perspectives for productivity analysis. The back grounds of different researchers and practitioners who work on this topic include such fields as economics, business administration, and industrial engineering, among others. Within each such field, there are different schools of thought on the theory and application of productivity analysis. Often it is not difficult to observe a lack of communication among the advocates of these separate schools. The purpose of this book is to present in a single volume samples of alternative approaches to productivity analy sis. This may be considered as a first step toward a better communication among practitioners and researchers in the fields of management, industrial engineering, and economics. The focus of the book is on the United States, where the productivity growth problem has been acute for some time. The book begins with a brief overview chapter that covers some of the issues involved in productivity analysis and a sample of methodological ap proaches presently in use. After this introduction, we move to Chapter 2 where Solomon Fabricant presents the issues related to measurement and analysis at the macroeconomic level. In Chapter 3, C. Lowell Harriss discusses concepts that he considers es sential for productivity growth: capital formation, technological progress, and freedom. 192 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -There is no shortage of general books on the subject of acid rain, or of symposium proceedings reviewing work ranging from atmospheric chemistry and deposition processes to freshwater acidification and effects on vegetation. In contrast, the collection of papers from this Workshop is focussed on a much smaller subject, the processes of acid deposition at high altitude sites. Interest in deposition at high elevation sites comes largely from observed vertical gradients in the degree of forest damage at sites in the Federal Republic of Germany and the eastern United States. These gradients show that damage to Norway spruce and fir increases with altitude at sites in Bavaria and the Black Forest, and that Red spruce are declining at high elevation sites in the Appalachian Mountains. With the large scale of scientific interest in forest decline, cany research groups, during the last five years, have been examining atmospheric chemistry, deposition processes, and effects on vegetation and soils at upland sites. In particular there have been many recent studies of cloud and precipitation chemistry, which show much larger concentrations of all ions in cloud water than in rain or snow. These studies have also shown that processes of wet and dry deposition and also the chemistry of the air at hill tops are modified strongly by orographic effects. 692 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Modern Cardiac Surgery is based on, but does not consist completely of, papers submitted at the annual course of cardiac surgery run by the combined Institutes and Post-Graduate Hospitals involved in cardiac surgery in London (1977). The subjects which have been chosen and included fulfil one of two criteria; either they are subjects which were not included in the previous book, The Current Status of Cardiac Surgery, or they cover subjects which needed to be updated. Because this is a teaching course and not a symposium, the emphasis has been on being informative rather than on presenting masses of results. The book has been prepared partly from manuscripts submitted by the authors and partly from annotated tapes of the proceedings of the meeting. Through out the editing and production of this book careful consideration has been given to the requirements of the readership. The book is aimed at all students of cardiac surgery and cardiology at all levels, and as much information as possible has been packed into it. Neverthe less, the editor wishes to thank the authors for the efforts they have made to be concise and clear in their presentation and for their tremendous co-opera tion in alterations which have been incorporated to make it a more readable treatise. This means that this is a book which is of value to nurses interested in cardiology in intensive care, to physiotherapists and students wishing to look up particular topics before their final examinations. 412 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Safety and Efficacy of Radiopharmaceuticals was established as a very important and comprehensive subject at the First Europe an Symposium on Radiopharmacy and Radiopharmaceuticals in Denmark in 1983. The interest in this subject has grown considerably since then due to the growing interest among national authorities to deal with radiopharmaceuticals. The introduction in recent years of nuclear medicine techniques based on radioactive labelled cells and on monoclonal antibodies has stressed the importance of a well functioning approval system for the clinical trial and use of new radiopharmaceuticals. The process of transferring the experience from the non radioactive drug field into the area of radiopharmaceuticals is still ongoing. International organisations such as the World Health Organisa tion is also including this into their quality assurance programme from both the radiopharmaceutical and the radiation hygiene point of view. In order to give an up-to date survey of these areas, experts were invited to prepare review papers under the following headings: Safety and Efficacy of Radiophar maceuticals with Emphasis on Biological Products, Radiophar macy/Radiation Hygiene, Legal Aspects of the Introduction of New Radiopharmaceuticals and some selected aspects of Good Radiopharmacy Practice. 388 pp. Englisch. …

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -An author should have a good reason before releasing another book to the general public or to students. We think that we have two. The first is that we both do research and teach a course dealing with soybean utilization, and we feel that both the students and instructors have suffered from lack of a suitable textbook. Second, there is a lot of emphasis in graduate programs in Food Science on developing courses of a highly specialized nature based on scientific disciplines rather than on food commodities. For example, the material we have covered in this text might be split into several courses on the chemistry of lipids, the chemistry of proteins, the unit processees of oil extraction, the nutritive aspects of oil seed products, and the food technology of oil seed products. These courses would treat many more commodities and chemical compounds than we have covered here, thus they would have achieved breadth in a different sense. 360 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -When compiling the present atlas our aim has been to provide the practis ing radiotherapist with a handbook which would help him to plan the radiation therapy of tumours of individual organs. Apart from a few ex ceptions, all isodose charts in this atlas show dose distributions resulting from external irradiation. Combination of external irradiation with intra cavitary radium therapy is presented in the treatment of carcinoma of the uterine cervix, in which case the two techniques are complementary. Thd immense material of the pertinent literature could, naturally, not have been included in the atlas. As a result of scrupulous selection, the isod-.:se charts shown may not invariably be the optimum ones, and some of them may not be the most modern. However, the usefulness of the information they provide has made us to keep them all the same. We did not intend to change the original charts in any way and stan dardization of the isodoses was not undertaken. Radiation parameters are given in the figure captions and, if available, information has also been provided on the phantoms used by the authors. Naturally, the isodoses presented will not automatically apply to all situ ations and all apparatuses without due attention to the individual patient ::Jnd technical details such as penumbra and source diameter. They merely serve as a starting point and will help to save time and work during treat ment planning also with the computer. 276 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This is the sixth in a series of volumes sponsored by the Department of Psychiatry of Baylor College of Medicine, each reviewing one broad category of psychiatric disorders. Earlier conferences have focused on well-established psychiatric categories such as depression, schizophrenia, and alcoholism. Psychosexual disorders are usually considered as a subgroup of psychiatric dis orders, and form one of the major categories of the DSM -III Classification of Mental Disorders. However, psychosexual disorders are also of concern to all physicians and clinicians, working in virtually every field of medicine. The whole area of human sexuality has been characterized by rapid advances during the last few decades. Notable contributions have been from psychoan alysis, from the work of Kinsey and associates, and particularly from the work of Masters and Johnson, which has led to new stress on psychosexual dysfunc tions, in addition to the earlier interest in paraphilias, gender identity disorders, etc. Still later there has been increasing emphasis on disorders of sexual desire. 208 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This new volume deals with a number of important and current topics in human nutrition that we hope will be of general interest to those concerned with this subject. We have first of all a chapter by J. S. Garrow and S. Blaza on energy requirements, which has a direct bearing on the problem of obesity, and which largely affects the populations of developed and afiluent countries. This is followed by a chapter on fluoride and the fluoridation of water, under the authorship of G. N. Jenkins. The addition of fluoride to drinking water has given rise to a great deal of discussion both amongst scientists and the public at large, and the present account tries to give the scientific background and a critical evaluation of established facts. The chapter by G. Owen on the nutritional status of North Americans is also likely to be of interest to other countries, as the techniques used and the problems encountered are similar to' those encountered in other parts ofthe world. A chapter on nitrates, nitrites and nitrosamines by S. R. Tannenbaum discusses a topic which again has engendered widespread interest amongst a large number of people, and where a balanced presentation of the relevant facts is particularly important. One of the fields in which biochemistry, physiology and nutrition have made enormous advances over the last few years is that of vitamin D and the new knowledge acquired on control of the metabolism of calcium and phosphorus. 260 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In all the industries in which I do management consulting, each manager considers his own industry to be truly 'unique. ' Of course, each is different in some respects, and each has its own quirks and features. However, the similarities among in dustries far outweigh the differences. The critical dynamics and the management issues have a great deal in common. However, there are, I believe, two industries (or segments of industries) that have an important critical uniqueness that does distinguish them from the rest. One of these is the exploration for undiscovered natural resources, notably for oil and gas; the other is research. In these two in dustry segments, the competition is not nearly so much one firm against another as it is each firm against 'nature,' or-if you prefer-against the unknown. This uniqueness not only sets these two industry segments apart from the rest, it also helps us to see what they have in common with each other: - Pure scientific talent, ability, and genius have direct commercial value. - We do not have the zero sum game of competition in the market place. A discovery by one firm does not usually perceptably lessen the opportunity of a 'competitor' for a discovery. On the contrary, a discovery by one firm usually increases the knowledge of the whole industry, increasing com petitors' opportunity for discovery. - We see the source of continuing life for the rest of the firm. 176 pp. Englisch.…

This XXV Anniversary Symposium, however, gives the opportunity of reminding us that in Belgium, where the risk of developing multiple sclerosis is among the highest in the world, a great man to whom we all pay tribute, I mean Dr Ludo van Bogaert, in 1957, took the initiative in founding the Belgian Research Group for Multiple Sclerosis. It may sound immodest but since that time members of the Belgian Research Group happen to have an honourable record of important contributions to MS research, quite out of proportion to the financial support they received for it. Indeed, when compared to the situation in English speaking countries, funding of MS research has always been neglected in our country in spite of the fact that in 1958, acting on the advice of the Belgian Research Group, the Belgian National MS Society was founded with the specific object of collecting money for research as well as for social care. At that time, the difficulty in raising funds for research was partly due to the fact that solving the problem of MS appeared almost impossible. Scientists could apparently only too slowly improve their ability to prevent and cure the disease. Media were indifferent to MS which was considered to have no news value, and the public remained uninformed. 520 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The classical Appalachian, Caledonian, Hercynian, and Mauritanide orogens are now only segments of a once-continuous Paleozoic mountain belt which has been fragmented during Mesozoic-Cenozoic formation of the North Atlantic Ocean. These segments are major parts of the countries surrounding the North Atlantic - most of which are members of NATO. The aim of this NATO conference was to evaluate these fragments in terms of their pre-Mesozoic positions, and to attempt a synthesis of their geologic evolution on an international and orogen-wide scale. Geologists who have studied these scattered remnants have been separated by both geography and discipline. Orogen-wide syntheses have beeen attempted in the past by individuals who are specialists not only in discipline but also in geography; therefore, these attempts have not been satisfactory to everyone. This conference brought together the foremost specialists in different disciplines from each country. They attempted to teach other specialists, not only in their own fields, but in other disciplines, about regional variations and particular problems. The resulting international cross-fertilization, both within and between speciaLties, enriched individual workers and helped to provide a multi-disciplinary overview of the orogen. 416 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -There is now widespread recognition that emotional problems, to say nothing of the interactions of emotions with other manifestations of illness and disease, constitute a substantial component of all human suffering. For too long the pro vision of medical care has been restricted to the physical aspects of that suffer ing while the psychological aspects have been shunned. Whether through igno rance about the nature of emotional illness and its clinical management, or through uncertainty about the legitimacy of their ministrations, physicians and many other health professionals have left the care of psychiatric problems to psychiatrists and other mental health professionals. For a variety of reasons this strategy is no longer feasible and substantial changes are required. The extent of the needs, the nature of the presenting problems, the ex pectations of the patients, the prohibitive costs of alternative approaches, and the lack of trained mental health professionals make it imperative that general health workers learn to cope with the psychological and behavioral health prob lems of their patients. There are no other alternatives if the realities of comtem porary suffering, limited resources and psychobiological knowledge are accepted. It is to the pragmatic knowledge base for this essential component of contemporary health care that this book makes a seminal contribution. Dr. 240 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Immunology has become one of the most important of the life sciences. As research unravels the mystery of the lymphocyte, a central role of the immune system in health preservation has become evident. The paediatric immunodeficiency disorders or 'experiments of nature' have demonstrated the division of cellular and humoral immunity; specific functional defects are now readily identified. The tendency of persons with immune dysfunction to develop neoplasms has suggested that surveillance mechanisms within the immune apparatus prevent tumour development. Malignancies, in fact, do seem to provoke certain immune responses, begging numerous therapeutic questions. Transplantation surgery, or the demand for 'new parts' has led to description of those antigens important in tissue-typing. Genetic loci have been found responsible for transplantation antigen display; as well, they influence clinical resistance or susceptibility to a wide variety of infections, auto-immune or neoplastic diseases. Clinicians have been quick to recognize the therapeutic implications of laboratory work and to use this knowledge in disease treatment. Precise patient-tissue matching and immunosuppressive treatment make renal allo transplantation safer and more successful than ever before. Both paediatric and adult immune deficiency states are now often recognized; treatment may involve general immune support or specific manipulations with, perhaps, bone marrow or thymus grafts or treatment with lymphocyte transfer factor. Transplantation of bone marrow has been used not only to correct certain immune defects but to correct marrow failure of diverse origin. 372 pp. Englisch. …

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Few diagnostic methods in Cardiology have heralded such revolutionary developments as the introduction of coronary arteriography. When, in the early 1960's, Dr. F. Mason Sones demonstrated that visualization of the coronary anatomy in living humans was not only feasible but sufficiently safe and reliable to be used as a clinical tool in the evaluation of patients with known or suspected ischemic heart disease, the thus far somewhat neglected area of coronary circulation became the focus of interest. Naturally, for a considerable period of time a great deal of emphasis was placed upon coronary anatomy. Simple relations between narrowing lesions, impediment to flow, and prognosis were assumed to exist. Spectacular results of surgical coronary revascularization seemed to confirm this concept. Gradually it has become evident that the pathophysiology of coronary artery disease is considerably more complex. Diagnostic methods were introduced to assess and quantify exercise-induced myocardial ischemia. At first, these tests were used mainly to achieve a more discriminative selection of candidates for coronary arteriography and the coronary arteriogram remained the gold standard. Currently, these techniques have evolved to the point where they provide valuable functional and metabolic information. They have become powerful independent tools in clinical investigations and evaluation of individual patients. 256 pp. Englisch.…

WADE organized an international symposium on magnetic resonance in collo1d and in terface science which brought together a large number of scien tists from the United States and from abroad. The aim of this symposium was to include all experimental inorganic, organic and biochemical systems in which molecules are bound to interfaces and to show the contribution of various techniques based on ma gnetic resonance to the knowledge of these systems. This ambi tious program resulted into a very interesting gathering that initiated a more interdisciplinary approach to the problem of interfaces. Because of the success of this symposium it was sug gested that a similar meeting should be organized in Europe within the next three years. Professor J. FRAISSARD accepted this task but, conside ring the rapid developments in the theory and in the applica tions of the magnetic resonance spectroscopies, the organ1z1ng committee decided to arrange the meeting to be held in MENTON (France) in two parts, the first being a School and the second the Symposium proper. The former was' intended to review and to teach theoretical aspects as well as to discuss the experimental results derived from these advanced methods; the Symposium was to be for the discussion of the latest results at the highest level. 736 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Jaundice ofnewbom infants was described by several authors in the 17th century. The condition, however, was usually thought of as being similar to adult jaundice and due ro occlusion of the bile ducts by 'glutinous humours'. On the other hand, some writers reported on the fact that more than one consecutive baby was often affected, and there is a classic example of the disease in twins written by Louyse Bourgeois, the midwife of Marie de Medici, in 1609. It was not until early in the 20th century that it was realised that the common link between these familial cases was anaemia, and later still that this was of the haemolytic type. The breakthrough, in terms of an idea, came in 1938, when Darrow postulated that the baby's red cells were destroyed by an immune reaction on the part of the mother, the result of immunisation by paternal factors in the fetus. Shortly afterwards Wiener discovered an entirely new blood group system, 'Rh', and it was found that it was in compatibility within this system that was responsible for the vast majority of cases of haemolytic disease of the newborn. 332 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book stems from the belief that undergraduate, and many graduate, students in geomorphology are taught far too little about the theoretical foundation of the discipline. This is a tragic oversight because all disci plines exist solely by virtue of a body of theory; furthermore, all substan tive research must, of necessity, be directed at improving this body of theory. While the centrality of theory is a characteristic of all science, it appears that it is fieldwork that has achieved sacrosanct status in geo morphology. The supreme standing of fieldwork would seem at first sight to be supported by such comments as that cited by Ager (1984, p. 42): 'My old professor - the great H. H. Read - once said, 'The best geologist is, other things being equal, he who has seen the most rocks'. ' The key issue in Read's comment is obviously 'other things being equal'; what are these other things For they will be just as applicable to geomorphology as to geology at large. One is certainly personal ability, but another critical com ponent is the individual's knowledge of relevant theory. Pursuit of theo retical knowledge is not generally a favored activity in geomorphology, a situation epitomized by Chorley's (1978, p. 1) one-liner: 'Whenever anyone mentions theory to a geomorphologist, he instinctively reaches for his soil auger. 268 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Immunology is a rapidly developing subject. The contributors in this book present some components of immunological knowledge which relate to the present and the possible future practice of surgery. Aspects of cellular and humoral immunity necessary for understanding are described and considera tion given to the mechanisms underlying immunological diseases. Whilst the original interest in immune response was related to microbial resistance, the recent impetus to surgical immunology has been the resurgence of organ grafting. Separate sections of the book deal with clinical organ transplanta tion, the allograft reaction, graft rejection and immunogenetics. A pre-requi site of successful organ grafting is suppressive control of immune responses. Approaches to conventional immunosuppression and specific non-reactivity are therefore considered. One method of cancer therapy is strengthening of the host's immune responses. Both experimental and clinical immunotherapy are discussed and components of tumour immunology necessary for their rational understand ing are dealt with separately. Successful immunotherapy requires monitoring of immune responses but another method for improving results of cancer treatment is earlier diagnosis by immunological methods. The book is aimed at practising surgeons who want to know the relevance of immunology to clinical surgery and laboratory scientists needing to understand the applications of their basic concepts. I am very grateful both to the authors for their contributions and the editorial staff of MTP Press Limited, for their considerable help. 412 pp. Englisch. …

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Despite a plethora of theories, premenstrual syndrome (PMS) has remained an enigma. There has persisted in the literature a constant conflict as to the existence of the syndrome, a question as to whether it is one syndrome or several, and a debate as to whether the origin is psychic, somatic, or both. Advances in endocrinology, specifically in radioligand assays, allowing for accurate hormone measurements, have precipitated a more scientific evaluation of PMS in recent years. Nonetheless, diffi culties have persisted in accumulating well-documented data because of the protean nature of the syndrome. Indeed, even at this time, the question of what requires measurement during the follicular phase of the cycle and the premenstrual phase remains unresolved, and is difficult to place in perspective. In view of the persisting conflict between the organic and the psychological schools of thought, we, the editors of this book, considered the Sixth International Congress of Psychosomatic Obstetrics and Gynecology to be an ideal venue for a workshop in which both parties could be encouraged to participate. Towards this end, the organizing committee of the Inter national Society of Psychosomatic Obstetrics and Gynecology (ISPOG) was approached, and their response was extremely encouraging. In this respect, we wish to record our thanks to the Scientific Committee oflSOPG for allowing this workshop to be organized under their auspices, but totally under our direction. We, in turn, stand responsible for the format and content of the workshop. 124 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -The management of chronic renal failure by dialysis and transplantation has now become an established form of treatment in many parts of the world. However, these forms of treatment have brought with them problems in relation to the selection of patients, economics, clinical problems such as hypertension, encephalopathy, anaemia and renal bone disease, and psychological and social problems. The management of haemodialysis has changed over the years with developments in dialysers, vascular access and the duration of dialysis. Although the overall survival from renal trans plantation has changed little in the past four or five years, there are hopes of improvements in relation to tissue typing and enhancement. Perhaps the most important aspect in the management of chronic renal failure is the multi-disciplinary approach. Nursing and medical staff work closely with dialysis technicians, engineers, dietitians, local authority per sonnel, social workers and with the relatives of the patients. The symposium was planned to draw together representatives from all disciplines involved in the care of patients with chronic renal failure. One of the most relevant sessions was that in which two patients with chronic renal failure described their experience. 304 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -The ASI on Nonlinear Model Based Process Control (August 10-20, 1997~ Antalya - Turkey) convened as a continuation of a previous ASI which was held in August 1994 in Antalya on Methods of Model Based Process Control in a more general context. In 1994, the contributions and discussions convincingly showed that industrial process control would increasingly rely on nonlinear model based control systems. Therefore, the idea for organizing this ASI was motivated by the success of the first one, the enthusiasm expressed by the scientific community for continuing contact, and the growing incentive for on-line control algorithms for nonlinear processes. This is due to tighter constraints and constantly changing performance objectives that now force the processes to be operated over a wider range of conditions compared to the past, and the fact that many of industrial operations are nonlinear in nature. The ASI intended to review in depth and in a global way the state-of-the-art in nonlinear model based control. The list of lecturers consisted of 12 eminent scientists leading the principal developments in the area, as well as industrial specialists experienced in the application of these techniques. Selected out of a large number of applications, there was a high quality, active audience composed of 59 students from 20 countries. Including family members accompanying the participants, the group formed a large body of92 persons. Out of the 71 participants, 11 were from industry. 932 pp. Englisch.…

It has come to be understood that grains playa role in processes other than the simple absorption and scattering of starlight, which was all that the astronomers of a generation aga considered to be their relevance. Grains indeed playa critical role in controlling the temperature, composition, and states of aggregation of the whole interstellar medium. Among the still mysterious problems is the origin of the vast clouds of obscuring material that is observed in radiogalaxies like NGC 5128 and M 82, which may weIl be associated with the explosions of very massive objects. It is safe to say that from this growing field of study much still remains to be dis covered. The topics discussed in this volume will make clear to the reader the range and versatility of the subjects. F. HOYLE FOREWORD by THE PRINCIPAL The Symposium on Solid State Astrophysics held in July 1974 brought to University College Cardiff a large and very distinguished gathering of astronomers. It was the first time that such a collection of scholars, absorbed with the problem of the systems of outer space, had collected together in Wales, and so provided a splendid spring board for the researches of the newly founded group of astronomers in the Department of Applied Mathematics and Astronomy at University College. 332 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -Being small, shapeless and inert a gas molecule does not seem to be an enzyme's dream of a substrate. Nevertheless evolution has provided a host of enzymes which can interact specifically with gas molecules such as oxygen, carbon dioxide, nitrogen, hydrogen etc. Many of these enzymes play dominant roles on the world scene in biogeochemical cycles. On the cellular level they tend to be closely connected to the energy conserving apparatus. We define Gas Enzymology as the study of these enzymes. Historically, Gas Enzymology is a subspecialty of bioenergetics. Its foundations, technical as well as conceptual were laid by Warburg in his studies of the cellular combustion of nutrients. The Warburg apparatus supported the first thirty years of research in the field. It was succeeded by the Clark electrode which had its heyday during the period when the modern concepts of bioenergetics took shape. The Clark electrode, itself approaching thirty years of age, is now being sup plemented and in some cases replaced by the vastly more powerful membrane inlet mass spectrometer which measures with equal ease all dis solved gases of interest in biochemistry. It is our belief that future development of Gas Enzymology will be linked to the widespread exploit ation of this technique. 264 pp. Englisch.…

The objectives of the School were twofold. Firstly to inform participants of actual and developing technolog ical applications of glassy materials in which fundamental science makes a strong contribution, and secondly to bring together scientists from the widely different backgrounds of glass science and technology to promote mutual understanding and collaboration. The amorphous state has for more than a decade now been a renaissance of scientific and technological activity extending beyond traditional glass technology research. Striking developments of amorphous materials have been made in fields such as metallurgy, electronics and telecommunications and even in disciplines until recently less concerned by materials science, such as colloid chemistry, medicine and agriculture. The physical and chemical properties brought into application here result from the interaction between the glass composition and its non-crystalline structure. One role of the basic research is to understand this interaction, which in time through development, helps to extend the range of properties and applications. In this meeting we hoped to sensitize participants to the vast range of applications of amorphous materials which exploit their unique properties, and thus broaden future investigation. The program was organised around seven topics, signposts of scientific and technological activity in the 1980'S: optical materials, amorphous metals, crystallisation phenomena, electronic and electrical devices, sol-gel preparative methods, composite materials and long-term applications. 740 pp. Englisch. …

Successive waves of advance in knowledge gather, break and recede uncovering fresh challenges and new opportunities. Each plays its part in eroding the tidemark of yesterday's ignorance. Many involved in the day-to-day management of patients, ill prepared and ill-equipped by the training which they received as under graduate students, find it difficult to retain contact with the advances in medical science and feel uncomfortable on the shifting sands of uncertainty upon which we now stand. Which of the new ideas is sound Upon which data may we rely How may we distinguish the real from the unreal, the true from the false, recent advances from recent retreats These are the anxieties, often either unstated or alternatively expressed in terms of an attitude of total opposition to 'all of this research rubbish' which are widespread in medical circles today. It is for these individuals who are not themselves directly involved in the immunology of rheumatic diseases but who, nevertheless, recognize the importance of this subject to their patients and, in particular, to tomorrow's patients, that this book has been written. There are two points that I believe to be of central concern. Firstly, I think it important to recognize that the intellectual basis of most of the research work being generated today is actually extremely simple. 276 pp. Englisch.…

GREENBLATT The original oral contraceptives contained more oestrogen in the form of ethinyloestradiol or mestranol and progestagen in the form of norethynodrel or norethisterone than was necessary f(x conception control. There has been a trend over the years to reduce dosages of both components in order to minimize side eHects while ensuring eflcctiveness. However, as dosages were lowered, there has been an increase in spotting and break through bleeding during the first few months of their adminis tration. The sequential pill appeared more physiological in that it followed more closely physiological principles, but the need to employ large doses ofEE or EE3ME to inhibit O'ulation and the higher pregnancy rate made the sequential regimen less attrac ti'e or useful. A triphasic formulation has become available that takes advantage of the synergism between ethinyloestradiol and the potent levonorgestrel so that low doses of the oestrogen and very low doses of the progestagen could be employed with great effectiveness. Such a preparation is relatively free from side effects, partly because the basic pharmacological tenet of the minimal dose for the desired result and the division of'the cycle into three parts using 30 ,lIg ofEE for the first 6 days, then:) days of 40 ,lIg, followed by 30 ,fIg for 10 da ys, for a total of21 days, thus more or less mimicking the physiological rise and fall of 125 THE DEVELOP:'IE:-;T OF , :-;E' TRIPH.

IIONEYMAN The second textile and clothing research and development programme (1982-1985) supported by the EEC was undertaken with the prime objective of strengthening the competitiveness of the Community textile industries by stimulating innovation. From the generation of the research ideas through to the application of new technologies, the optimum conditions for scientific research demand highly trained and qualified people working in well-equipped laboratories. The Commission, in collaboration with the textile industries working through Comitextil, participated in the selection of suitable topics and supported the implementation of the programme and the publication and dissemination of the results. In all, 24 institutes in seven member countries carried out the programme which was divided into 35 separate but co-ordinated contracts. The costs were shared equally between the Commission and the participat ing institutes. The results were presented by selected specialists at the closing symposium held in Luxembourg on the 18 and 19 September 1985. The technical sessions covered the four topics : garment physiology and construction, quality of knitted fabrics and articles, application of new spinning technologies in the wool industry, and the upgrading of linen. In addition, prominent industrialists and Commission officials presented papers concerned with the present situation and the prospects for textile manufacture in the Community. Possible future research topics were outlined and the need was stressed for an increase in the amount of research and development to be carried out. 500 pp. Englisch.…
