Taschenbuch. Condizione: Neu. Neuware -EXCEPT for chapter 8, an editorial foot-bridge across the con fused years which separate the Dutch Republic from the King dom of the Netherlands, the essays collected in this volume were originally read and discussed at meetings of Dutch and British historians held between 22 and 27 September 1969 in a number of delightful comers of Groningen and Friesland. That this con ference took place at all was due in the first instance to the initiative and organizing genius of the Instituut voor Geschiedenis of the University of Groningen: particular thanks are due to the Rector Magnificus and his colleagues of that illustrious place of learning. On behalf of those fortunate enough to take part, we also wish to place on record our deep gratitude for the benevolent assistance of the Netherlands Ministerie van Onderwijs, of the H. S. Kammingafonds and of the Groninger Universiteitsfonds. As our sub-title strives to hint, the conference papers were commissioned with a view to stimulating historical awareness of a problem which is increasingly forcing itself on the attention of contemporary statesmen, administrators, sociologists and others - indeed of all who value local character and the human scale in the age of mass communications and socialized government.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Every day people frequently have to make a choice. For practical and scientific reasons therefore it is interesting to know what choices they make and how they arrive at them. An approach to this question can be made via psychology. However, it is also possible to approach it on a more formal basis. In this book Dr. Wedde pohl describes the logical structure of an individual's rational choice. It is this formal, logical approach to the decision problem that makes the book interesting reading matter for all those who are engaged in the study of individual choice. The introduction apart this study may be divided into two parts. The first part, consisting of chapters II and III, deals with choice theory on a very abstract level. In chapter II some mathematical concepts are presented and in chapter III two related choice models are treated, the first one based on preferences, the second one on choice functions. The second part consists of chapters IV, V and VI and covers consumer choice theory. After the pre sentation of the mathematical tools, two models that are extensions of the models of chapter III are dealt with. In the discussion of consumer choice theory the concept of duality plays an important role and it is found that duality is closely related to the notion of favourability introduced in chap ter II I. Mr. Weddepohl's study forms an introduction to a larger research project to develop the theory of collective choice. 184 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The introduction of public goods into economic theory has recently received substantial attention from economists. Both the increasing significance of public goods and the deficiencies of the private goods-oriented allocation mechanisms call for a re orientation of the classical general equilibrium models such as the one designed by Walras exactly a century ago. Although several approaches to this problem are possible, the duality approach seems to be very fruitful. In this study, Dr. Ruys applies and develops the mathematical theory of polarity to gain a deeper insight into the economic theory of value. He not only uses the duality approach to simplify formal proofs related to public goods, but he also gives an interpretation to the application of polarity operations which goes far, beyond its formal significance. This study is in a way closely related to the publication 'Axiomatic choice models' by Dr. H. N. Weddepohl, which is volume 3 of the Tilburg Studies on Economics. 252 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Birth defects have assumed an importance even greater now than in the past because infant mortality rates attributed to congenital anomalies have declined far less than those for other causes of death, such as infectious and nutritional diseases. As many as 50 % of all pregnancies terminate as miscarriages, and in the majority of cases this is the result of faulty intrauterine development. Major congenital malformations are present in at least 2 % of all liveborn infants, and 22 % of all sti1Ibirths and infant deaths are associated with severe congenital anomalies. Not surprisingly, there has been a great proliferation of research into the problems of developmental abnormalities over the past few decades. This series, Advances in the Study of Birth Defects, was conceived in order to provide a comprehensive focal source of up-to-date information for physi cians concerned with the health of the unborn child and for research workers in the fields of fetal medicine and birth defects. The first four volumes featured recent experimental work on selected areas of high priority and intensive investigation, including mechanisms of teratogenesis, teratological evaluation, molecular and cellular aspects of abnormal development, and neural and behavioural teratology. It seems logical and timely that the clinical aspects should now be presented. Accordingly, leading experts were invited to review a broad range of common problems from the standpoint of embryology, aetiology, clinical manifestations, diagnosis and management. This volume deals with cardiovascular, respiratory, gastrointestinal, and genitourinary malformations. 248 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is now thirty years since William Montagna and Richard Ellis edited 'The Biology of Hair Growth'. In his introduction, Stephen Rothman, of the University of Chicago, USA and one of the driving forces behind research on skin at the time, wrote: 'The pilary system is a perfect micr9cosmic structure. In this microcos mos we find birth, development, ageing and death, activity and rest, color for mation and decolorification, greasiness and dryness, infection and sterilization, hypertrophy and atrophy, Qenign tumours and malignant ones. ' He foresaw the human pilary system as a model for the study of a multitude of human diseases including ageing and cancer. It was not, how ever, until the seventies that the development of micro-biochemical tech niques indeed allowed the use of the human hair follicle as a convenient biopsy tissue for Biomedical Research in general. Measurement of enzyme activities, and important co-factors, and culturing of cells from single follicles all became possible. In the eighties dermal papilla cells were grown in cul ture and this opened the way to study hair differentiation in vitro. Studying hair differentiation is, in fact, studying growth regulation and it is this aspect that by far transcends the importance of studying hair growth itself. Let us not forget that metastatic prostate cancer is treated with the same drug -cyproterone acetate -that is used for the treatment of alopecia and hirsutism in women. 348 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -IRVING LEVESON The 19608 was a period of rapid social and economic change, coupled with spectacular growth in the role of government in dealing with social issues. The demands of public programs and policies created enormous pressures for improved information and analyses. In the field of drug abuse these pressures were compounded by the rapid rise of drug use and the absence of much critical information and analysis. The most elementary steps to develop a data base were just beginning, and many years of effort would be required before the accumulation of knowledge could produce. a strong foundation for public policy. There has been enormous progress in improving knowledge about drug abuse since the mid-1960s. However, as in many fields, research has concentrated on a few questions while others largely are ignored, and even where studies exist there are problems of assimilation. Information is widely dispersed, not always accessible and often not in the most useful form. Many analysts do not have adequate understanding of the ways in which studies might enter into policy development, while at the same time, persons responsible for policy formation often do not have sufficient knowledge of how to use research to help resolve policy issues. A major objective of this volume is to illustrate the formation of linkages which may bridge the gap between research and policy. 216 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Fundamental to survival of living organisms is their ability to react appropri ately to their environment. Cannon (1929) recognized that 'back of internal homeostatic mechanisms are powerful motivating agencies-appetites and hunger and thirst.' Almost all observed behavior may be viewed as activity required to meet some physical or emotional need. 'The higher in the scale of living things, the more numerous, the more perfect, and the more compli cated do these regulatory agencies become.' This statement by Fredricq (1885) regarding internal mechanisms is at least as valid for behavior. Adrenal medullary secretion in preparation of 'fight or flight' may be con sidered the first described behavioral neuroendocrine response. The conse quences of more prolonged stress on pituitary-adrenal cortical function and the subsequent unfolding of the means by which the brain controls the secre tion of the anterior and posterior pituitary glands led to the birth of neuroen docrinology. During the last decade, neuroendocrinology has taken a remarkable turn. Peptides which were believed at first to be involved solely in control of the pituitary by the hypothalamus were found in other areas of the brain. Other peptides were encountered in brain by their activity in competing for the high affinity binding of drugs to their receptors, and still others, first found in peripheral organs, were discovered also in brain. Perhaps even more amaz ing was the discovery that one or another of these peptides influence almost every aspect of behavior. 960 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this volume I have attempted to cover the more important aspects of immunosuppressive therapy. In doing this, I have been very fortunate in securing the help of the distinguished authors who have contributed the chapters that follow and I am grateful to them for providing such thorough and up-to-date accounts of their subjects. Immunosuppression can be mediated by many hundreds of agents and it has been difficult to strike a balance between the 'small print' of drug action in animals and the useful ness or otherwise of drugs and other agents for inducing immunosuppression in patients. The first six chapters deal mainly with the experimental aspects of lmmunosuppression and include a full discussion of total lymphoid lrradiation and cyclosporin-A. Both these agents have shown great promise recently as forms of immunosuppression in animals and undoubtedly will come to be used more and more in patients recelvmg transplants of one form or another. The last four chapters are devoted to the use of the more traditional immunosuppressive agents for specific clinical conditions. In her chapter on renal transplantation, Dr McGeown describes in great detail not only the immunosuppressive regime she employs but the general manage ment of transplant patients. The clinical results have been so good in her unit that I felt her account should include these other aspects of treatment since they would seem to be just as important as the immunosuppressive regime she uses. 272 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume contains almost complete proceedings of the NATO Advanced Study Institute (ASI) organised in 1979 to bring together principal innovators and numerous users of mathematical techniques for analysing the interaction of electromagnetic waves with engineering and biological structures. The mathematical disciplines which can be brought to bear on these problems necessitate examination of effectiveness, convergence and robustness of the derived analytic and num~rical algorithms. The aim of this ASI was to give a clear and up-to-date tutorial presentation of available techniques, and to bring together interested scientists, engineers and mathematiciaris, to discuss together their experience and to ensure wider familiarity with the subject. Our programme consists of three distinct yet related parts. The first two of these reflect two somewhat different methods applicable for different ranges of L/A, where L represents a characteristic dimension of a structure and A is a representative wavelength-of radiation. The third part deals with the specific problem of biological interaction. In the first part (Low and Intermediate Frequency Applications) we offer tutorial texts and user-oriented discussions on main techniques and problems concerning: radiation, scattering, aperture penetration, inverse scattering, using moment methods and their developments. The approach to the high frequency applications forms the subject of the second part of this volume, concentrating mainly on the geometrical theory of diffraction (GTD). There are three main variants of the GTD: uniform theory of diffraction (UTD), uniform asymptotic theory (liAT) , spectral theory of diffraction (STD). 928 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Architectural stress is the inability of a system design to respond to new market demands. It is an important yet often concealed issue in high tech systems. In From scientific instrument to industrial machine, we look at the phenomenon of architectural stress in embedded systems in the context of a transmission electron microscope system built by FEI Company. Traditionally, transmission electron microscopes are manually operated scientific instruments, but they also have enormous potential for use in industrial applications. However, this new market has quite different characteristics. There are strong demands for cost-effective analysis, accurate and precise measurements, and ease-of-use. These demands can be translated into new system qualities, e.g. reliability, predictability and high throughput, as well as new functions, e.g. automation of electron microscopic analyses, automated focusing and positioning functions.From scientific instrument to industrial machine takes a pragmatic approach to the problem of architectural stress. In particular, it describes the outcomes of the Condor project, a joint endeavour by a consortium of industrial and academic partners. In this collaboration an integrated approach was essential to successfully combine various scientific results and show the first steps towards a new direction. System modelling and prototyping were the key techniques to develop better understanding and innovative solutions to the problems associated with architectural stress.From scientific instruments to industrial machine is targeted mainly at industrial practitioners, in particular system architects and engineers working on high tech systems. It can therefore be read without particular knowledge of electron microscope systems or microscopic applications. The book forms a bridge between academic and applied science, and high tech industrial practice. By showing the approaches and solutions developed for the electron microscope, it is hoped that system designers will gain some insights in how to deal with architectural stress in similar challenges in the high tech industry. 124 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This book is about music. the instruments and players who produce it. and the technologies that support it. Although much modern music is produced by electronic means. its underlying basis is still traditional acoustical sound production. and that broad topic provides the basis for this book. There are many fine books available that treat musical acoustics largely from the physical point of view. The approach taken here is to present only the fundamentals of musical physics. while giving special emphasis to the relation between instrument and player and stressing the characteristics of instruments that are of special concern to engineers and technicians in volved in the fields of recording. sound reinforcement. and broadcasting. In order to understand musical instruments in their normal performance environments. the student must have a basic working knowledge of physical and architectural acoustics. The book begins with a review of the elements of acoustics. stressing the nature of sound fields and phenomena that are wavelength-dependent. The book then moves on to a discussion of those aspects of psychological acoustics that are of special concern to music technicians. most notably concepts of stereophonic imaging. loudness-related phenomena. and critical band theory. 304 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The technical importance of flexible composite structures needs no emphasis nor has there been any lack of material descriptive of their manufacture or properties. The starting points of such descriptions have invariably been from the viewpoint of the rubber industry and the presence of a suitable textile has been taken for granted, its strength properties indicated and the technological content confined to the manufacturing process within the rubber industry. An attempt is made here to work from the textile outwards. Industrial fabrics are far heavier than garment textiles, are not produced in the same bulk quantities and need to be specially constructed to provide the balance of properties which will combine with those of the rubber to give the final. product. The most important composite structure formed from textiles and rubber is, of course, the pneumatic tyre. It may therefore seem strange that no chapter deals with this. The reason is quite simple. To deal with the structure and design of the pneumatic tyre in a similar depth of detail as is done here for conveyor or power transmission belting, or hose, would require disproportionate space; in fact, a second volume equal in size to the present one. This book discusses from the textile viewpoint the various reinforced rubber structures used industrially with the exception of the tyre. These other uses of industrial fabrics can be discussed in adequate detail and cover the whole range of the technology involved in the space available in the one volume. 288 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The use of gamma-emitting radionuclides for diagnostic imaging in nuclear medicine has been established for many years. Sophisticated gamma ray detecting camera systems and computer links enable the clinical investigator to image different regions of the body and to quantify organ function. Parallel developments have also occurred in the field of radiopharmaceuticals, and today a wide range of products is available that will exhibit specific uptake within target tissues following parenteral administration. For example, radioiodide is taken up by the thyroid and iodinated fatty acids can be used to image the myocardium. Labelled antibodies have been used with success to target certain tumours. The concept of targeting has also been considered by pharmaceutical scientists who wish to deliver drugs rather than radionuclides to specific sites in the body. The systems that have been employed are often physically similar to those used as radiopharmaceuticals (for example colloids, aerosols and liposomes). Furthermore, pioneering work by Digenis and others in the United States States and by Alpsten and co-workers (1976)in Sweden had demonstrated the potential of gamma scintigraphy for investigating the fate of tablets and capsules in the gastrointestinal tract of man in a non invasive way. In 1979, the Biopharmaceutics Research Group at Nottingham together with academic pharmacists from Manchester held a one-day syffiposium at Nottingham University to discuss how radio nuclides could be used in drug formulation studies to provide better approaches for the delivery of drugs to their sitesof action. 352 pp. Englisch.

Their prominence as important crops has been heightened through the last several decades due to an awareness on the part of consumers of the nutrient, and other obvious values they offer to the diet as 'fresh greens' which, at least in the United States, have become a daily table staple. As a result, acreage planted to leafy salad vegetable crops has expanded to a remarkable degree over the past few decades, making these crops an important segment of the agricultural and marketing industries. Published information on leafy salad vegetables has been-and is widespread and scattered. This book brings together all up-to-date information and is amply referenced throughout for further study and information. Similarities and differences among the species are discussed and provide insight into the place these species hold in the world cropping system and in the human diet. This approach in text organiza tion was made in an effort to be helpful to the widest type of readership: professional researchers and teachers, graduate and undergraduate stu dents, extension workers, farmers and other members of the horticultural community, and, perhaps, even lay readers who are the ultimate consumers. 280 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This birefs examines mortality among young children in the period from the seventeenth to the nineteenth century. It does so using several types and sources of information from the census unit England and Wales, and from Ireland. The sources of information used in this study include memoirs, diaries, poems, church records and numerical accounts. They offer descriptions of the quality of life and child mortality over the three centuries under study. Additional sources for the nineteenth century are two census-derived numerical indexes of the quality of life. They are the VICQUAL index for England and Wales, and the QUALEIRE index for Ireland. Statistical procedures have been applied to the numbers provided by the sources with the aim to identify effects of and associations between such variables as gender, age, and social background. The briefs examines the results to consider the impact of children's deaths upon parents and families, and concludes that there are differences and continuities across the centuries. 100 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -It goes without saying that atomic structure, including its dual wave-particle nature, cannot be demonstrated in the classroom. Thus, for most science teachers, especially those in physics and chemistry, the textbook is their key resource and their students' core source of information. Science education historiography recognizes the role played by the history and philosophy of science in developing the content of our textbooks, and with this in mind, the authors analyze more than 120 general chemistry textbooks published in the USA, based on criteria derived from a historical reconstruction of wave-particle duality. They come to some revealing conclusions, including the fact that very few textbooks discussed issues such as the suggestion, by both Einstein and de Broglie, and before conclusive experimental evidence was available, that wave-particle duality existed. Other large-scale omissions included de Broglie's prescription for observing this duality, and the importance of the Davisson-Germer experiments, as well as the struggle to interpret the experimental data they were collecting. Also untouched was the background to the role played by Schrödinger in developing de Broglie's ideas. The authors argue that rectifying these deficiencies will arouse students' curiosity by giving them the opportunity to engage creatively with the content of science curricula. They also assert that it isn't just the experimental data in science that matters, but the theoretical insights and unwonted inspirations, too. In addition, the controversies and discrepancies in the theoretical and experimental record are key drivers in understanding the development of science as we know it today. 56 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Nutrient Indicator Models for Determining Biologically Relevant Levels: A case study based on the Corn Belt and Northern Great Plain Nutrient Ecoregion is the first book to provide answers to the management of nutrients based on changes in biological communities. The text describes a case study that is the result of a large scale project in the Corn Belt and Great Plains Nutrient Ecoregion. This study is the first to identify relationships between fish assemblages and nutrient concentrations by Nitrogen species. Species optima based on sensitivity and tolerance to nutrients is modeled. Nutrient Biotic indices calibrated for application are based on the results of years of biological indicator development. Test response intervals and Shift response intervals are formulated and validated against relevant biological assemblage shifts. This case study is the first to suggest recommended values for the nitrogen and phosphorus cycle with identifiable shifts caused in biological assemblages. This will provide watershed and environmental managers with the information needed to manage the inputs into the world's dead zones. 76 pp. Englisch.

That this con ference took place at all was due in the first instance to the initiative and organizing genius of the Instituut voor Geschiedenis of the University of Groningen: particular thanks are due to the Rector Magnificus and his colleagues of that illustrious place of learning. On behalf of those fortunate enough to take part, we also wish to place on record our deep gratitude for the benevolent assistance of the Netherlands Ministerie van Onderwijs, of the H. S.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book was originally published as a doctoral thesis and was de fended by the author at the Tilburg School of Economics in 1969. It has the characteristics of a work on industrial econometrics. On the one hand relevant economical, statistical and mathematical theory is treated and on the other a model for a very actual situation has been created and utilised to solve a practical problem. The selection from current reference material always has a personal tinge of course, and other theoreticians will find some of the author's departures from the theme a little unnecessary. However, if the theory propounded in this book is tested for its relevance in solving practical problems, the selection may be regarded as a success. Thanks to the way in which the case is developed the book is of great practical use. So often in writings on operations research theory is applied to so-called practical examples, which in fact can only be des cribed as five finger exercises. It is clear from the early chapters that the author has struggled with this problem but that he has found a solution. And in his concluding remarks he indicates briefly how this case can be incbrporated in a context which goes beyond short-term optimisation. In the description of the preparatory and implementation phases the author shows how a clash between practical implementation and theoretical application can successfully be avoided in this preparatory work. 196 pp. Englisch.

Tinbergen in his well-known 19- publication: 'A Method and its Application to Investment Activity', to the empirical testing of increasingly explicit theories of production behaviour. It was principally D. Jorgenson who gave a great push to this intensified interest in micro-economic investment, with his famous 1965-paper: 'Anticipation and Investment Behaviour', in which he formulated a pure neoclassical model of investment behaviour under the conditions of a (simple) homogeneous production technology and perfectly competi tive markets. But, although the scope of the familiar flexible accelerator model was considerably extended by the introduction of relative factor prices, the resulting investment relationship generally remained one of the most ill-estimated equations in econometric models. The very rigid assumptions of pure neoclassical models might have caused these bad results. More over, the required ex post measure for aggregate capital stock is very deficient for most economies. Hence, it should be interesting to formulate investment models subject to less rigid restrictions on production and market behaviour and, preferably, not containing any measure of aggre gate capital stock. 356 pp. Englisch.

I believe that anyone dealing with Yugoslavia has found it difficult to escape the spell of this fascinating country. There is its history, rich in struggles and achievements, its cultural heritage, the beauty of its land scapes and, last but not least, the character and qualities of its people. But while anyone of these features (to which others could easily be added) may have its special appeal depending on one's personal inclinations, it is undoubtedly Yugoslavia's socio-economic system that arouses universal interest. For some it represents the only system that eventually can ensure a just society, while for others its theoretical foundations are utopian and its practical implementation an incoherent muddle. The debate in the West about the merits of Yugoslav socialism will continue for a long time, and if at this stage a personal comment is called for then it must be that I have been struck by two things: modesty and courage. The Yugoslavs are surprisingly modest about the achievements oftheir system. There is no missionary zeal to export their social philosophy. 272 pp. Englisch.

The Symposium sessions were chaired by Eric Briscoe, who also introduced the Symposium with the very appropriate review 'Ceramics in Europe'. The term 'engineering ceramics' is commonly taken to mean a group of special high-strength and heat-resistant ceramic materials developed almost exclusively for the advanced internal combustion engine of the next century. It is not always fully appreciated that high grade fine microstructure ceramics both of the oxide and of the non-oxide classes, whether they be termed engineering, fine, special, advanced, structural or technical, have been supporting a large number of diverse and profitable industries over many decades. Indeed, in some respects these materials can be regarded as natural developments from the long established refractories field, and the distinction between an engineering ceramic and a refractory can become blurred, as the contribution in this volume on 'Nitride Bonded Carbide Engineered Ceramics' shows. It is of significance that in Japan, for example, much development work in the engineering ceramics field was initiated by the refractories industries, seeking to diversify possibly but doing so on the basis oflong experience in the refractories area. The main objective of this Symposium was to help engineers and designers to assess the present state of the field of engineering ceramics. 220 pp. Englisch.
