Taschenbuch. Condizione: Neu. Neuware - That residues of pesticide and other contaminants in the total environ ment are of concern to everyone everywhere is attested by the reception accorded previous volumes of 'Residue Reviews' and by the gratifying enthusiasm, sincerity, and efforts shown by all the individuals from whom manuscripts have been solicited. Despite much propaganda to the con trary, there can never be any serious question that pest-control chemicals and food-additive chemicals are essential to adequate food production, manufacture, marketing, and storage, yet without continuing surveillance and intelligent control some of those that persist in our foodstuffs could at times conceivably endanger the public health. Ensuring safety-in-use of these many chemicals is a dynamic challenge, for established ones are continually being displaced by newly developed ones more acceptable to food technologists, pharmacologists, tOxicologists, and changing pest control requirements in progressive food-producing economies. These matters arc of genuine concern to increasing numbers of gov ernmental agencies and legislative bodies around the world, for some of these chemicals have resulted in a few mishaps from improper use. Ade quate safety-in-use evaluations of any of these chemicals persisting into our foodstuffs are not simple matters, and they incorporate the considered judgments of many individuals highly trained in a variety of complex biological, chemical, food technological, medical, pharmacological, and toxicological disciplines.

Taschenbuch. Condizione: Neu. Neuware - Worldwide concern in scientific, industrial, and governmental com munities over traces of toxic chemicals in foodstuffs and in both abiotic and biotic environments has justified the present triumvirate of specialized publications in this field: comprehensive reviews, rapidly published progress reports, and archival documentations. These three publications are integrated and scheduled to provide in international communication the coherency essential for nonduplicative and current progress in a field as dynamic and complex as environmental contamination and toxicology. Until now there has been no journal or other publication series reserved exclusively for the diversified literature on 'toxic' chemicals in our foods, our feeds, our geographical surroundings, our domestic animals, our wild life, and ourselves. Around the world immense efforts and many talents have been mobilized to technical and other evaluations of natures, locales, magnitudes, fates, and toxicology of the persisting residues of these chemicals loosed upon the world. Among the sequelae of this broad new emphasis has been an inescapable need for an articulated set of authorita tive publications where one could expect to find the latest important world literature produced by this emerging area of science together with documentation of pertinent ancillary legislation.

Taschenbuch. Condizione: Neu. Neuware - For some time now, the study of cognitive development has been far and away the most active discipline within developmental psychology. Although there would be much disagreement as to the exact proportion of papers published in develop mental journals that could be considered cognitive, 50% seems like a conservative estimate. Hence, a series of scholarly books devoted to work in cognitive devel opment is especially appropriate at this time. The Springer Series in Cognitive Development contains two basic types of books, namely, edited collections of original chapters by several authors, and original volumes written by one author or a small group of authors. The flagship for the Springer Series is a serial publication of the 'advances' type, carrying the subtitle Progress in Cognitive Development Research. Each volume in the Progress sequence is strongly thematic, in that it is limited to some well-defined domain of cognitive developmental research (e.g., logical and mathematical development, development of learning). All Progress volumes will be edited collections. Editors of such collections, upon consultation with the Series Editor, may elect to have their books published either as contributions to the Progress sequence or as separate volumes. All books written by one author or a small group of authors are being published as separate volumes within the series.

Neuware - The rapid and continuous upsurge of interesting data in the subject of tumor immunology necessitates the publication of an annual series to furnish the updated materials to the students, researchers, and clinicians in this rapidly advancing field. Concepts and methodologies are ever changing. Also, current research in tumor immunology promises to offer breakthroughs in the future. Important is the need to communicate to the right people the exact role of immunodiagnostic methods and immunological intervention in cancer preven tion and treatment. The role of immunotherapy in combination with conven tional modalities of treatment needs to be understood in its proper perspective. Oncogene, interferon, lymphokines, monoclonal antibodies, natural killer cells, platelet-mediated cytotoxicity of antibody-coated target cells, suppressor cells, platelet-derived factors, plasma-blocking factors, control of suppressor cell func tion, abrogation of plasma-blocking factors, and so forth, are some of the areas that are continually advancing. Progress in these areas will have implication in cancer therapy. Further, it is already understood that if immunocompetence of the host can be maintained at a reasonably good level, there exists the potential to increase the therapeutic indexes of conventional modalities of treatment. This series will attempt to present updated information in all these areas based on con tributed and solicited articles.

Taschenbuch. Condizione: Neu. Neuware - There is much evidence to suggest that prostaglandins may have a physiological role to play in the control of thyroid gland metabolism, although the precise nature of this role remains to be defined. Prostaglandins have been found in normal thyroid tissue, and there is evidence of increased levels in some, but not all, cases of medullary carcinoma of the thyroid. which may account for the associated diarrhea. Exogenous prostaglandins, like TSH, bind to thyroid plasma mem branes, stimulate the adenylate cyclase-cyclic AMP system, thyroid hormone secretion, iodide organification, colloid droplet formation, glucose oxidation, and 32p incorporation into phospholipids. Prosta glandins of the E series are the most potent, although their maximal effects are generally less than the maximal effects of TSH. The interrelationships existing between TSH and prostaglandins have been the subject of intensive investigation, but as yet no one uni fying concept has emerged. TSH and prostaglandins have been shown to occupy different receptors on the thyroid plasma membrane. Al though TSH can increase intracellular prostaglandin levels, probably as a result of increased synthesis, prostaglandins do not appear to be essential intermediates in TSH action on adenylate cyclase. The pos sibility that prostaglandins are part of a negative feedback system con trolling TSH action is, as yet, a tentative hypothesis, and further work will be required to unravel the interrelationships between these sub stances that now appear to be far more complex than has been envisaged thus far.

Neuware - The Symposium on Infrared and Submillimeter Astronomy was held in Philadelphia, Pennsylvania, U.S.A., on June 8-10, 1976, as an activity associated with the Nineteenth Plenary Meeting of the Committee on Space Research (CaSPAR). The Symposium was sponsored jointly by CaSPAR, the International Astronomical Union (IAU) and the International Union of Radio Science CURSI). caSPAR is an interdisciplinary scientific organization, established by the International Council of Scientific Unions in 1958, to, in the words of its charter, 'provide the world scientific community with the means whereby it may exploit the possibilities of satellites and space probes of all kinds for scientific purposes and exchange the resulting data on a co operative basis.' The purpose of this particular CaSPAR Sympo sium was to present new results in infrared and submillimeter astronomy obtained by observations on aircraft, high altitude balloons, rockets, satellites, and space probes. Topics dis cussed included the Sun, the solar system, galactic and extra galactic objects as well as the cosmic background radiation. Instrumentation for observations in infrared and submillimeter astronomy was also discussed, with particular emphasis on future programs from space observatories.

Neuware - Polymer composites were introduced for the aerospace industry as light, strong, stiff materials, and adopted by the construction and automobile industries, among others. Meanwhile, composite materials have been introduced to fulfill the uses that these conventional materials could not, such as in extreme environments. The research for new composites includes not only new polymer systems, but metals, ceramics and intermetallic systems as well. This volume contains a selection of recent work by leading researchers in micromechanics on the topics of prediction of overall properties of elastic, perfectly bonded systems, problems associated with inelastic deformation of the phase, debonding at interfaces and growth of distributed damage. Many familiar aspects of mechanical behavior, such as fatigue, fracture, strength and buckling, etc. have been reexamined and adapted for these new systems.

Taschenbuch. Condizione: Neu. Neuware - Clinical and pathological observations have unequivocally indicated an increase in the incidence of malignant neoplasia during the last two decades. Despite important advances in surgery, radiotherapy and chemotherapy, mortality from tumours still tends to increase. Cancer research has therefore concentrated not only on early diagnosis and therapy but also, in line with recent trends in medical science, on the prevention of oncogenesis. One effi cient prophylactic approach is the treatment of preblastomatoses, which include the preneoplastic lesions of the mouth. The most frequent oral pre cancerosis, leukoplakia, has been studied extensively during the last 20 years with regard to its pathogenesis,clinical course,and response to therapy. In Hungary, studies of oral leukoplakia have a century-long tradition. The term leukoplakia was coined by the Hungarian dermatologist Ern/) Schwimmer who recognized the precancerous nature of the condition and its relationship to tobacco smoking exactly 100 years ago. In the middle of this century another Hungarian scientist, Karoly Balogh established that most leukoplakias have two stages, - reversible and irreversible - and that early lesions may heal spontaneously after the elimination of irritational factors. The incidence of leukoplakia in random population groups was determined for the first time in the world by the Hungarian investigator Pal Bruszt, and reported to be 3.6 %. Subsequent studies in other countries confirmed a range of 0.2-8.1 %, depending on geographical and environ mental conditions, way of life, and relevant habits.

Taschenbuch. Condizione: Neu. Neuware - In recent years, it has become clear that the red-giant phase is one of the most dramatic periods in a star's life, when all of its parts become involved in ways that have both direct and indirect observational consequences. This is most particularly true of low- and intermediate mass stars during the second ascent of the giant branch. Such stars bring to their surfaces products of nucleosynthesis currently taking place in their deep interiors, they pulsate as Mira variables, develop extended outward-flowing atmospheres that may exhibit maser properties, and shed great quantities of matter, sometimes highly processed, into the inter stellar medium. The manner in which processed matter is brought to the surface is far from being completely explained, and the precise mechanism or mechanisms whereby matter is ejected from the stellar surface (whether by deposition of Alfven waves, radiation pressure on grains, or as a consequence of so me large scale envelope instability) has yet to be elucidated to every one's satisfaction. The purpose of the second workshop in Astrophysics, organized by the 'Advanced School of Astronomy', was to bring together experts on all the physical processes occurring in red giants in an effort to emphasize the interrelatedness of these individual processes, and to encourage a dia logue among experts that might serve to initiate a synthesis, or at least sharpen our understanding of the most important problems to address in the future.

' With these words of Kepler, Agassi plunges into the actual troubles and glories of science (321). The sociology of science is no foreign intruder upon scientific knowledge in these essays, for we see clearly how Agassi transforms the tired internalist/externalist debate about the causal influences in the history of science. The social character of the entire intertwined epistemological and practical natures of the sciences is intrinsic to science and itself split: the internal sociology within science, the external sOciology of the social setting without. Agassi sees these social matters in the small as well as the large: from the details of scientific communication, changing publishing as he thinks to 'on-demand' centralism with less waste (Ch. 12), to the colossal tension of romanticism and rationality in the sweep of historical cultures. Agassi is a moral and political philosopher of science, defending, dis turbing, comprehending, criticizing. For him, science in a society requires confrontation, again and again, with issues of autonomy vs. legitimation as the central problem of democracy. And furthermore, devotion to science, pace Popper, Polanyi, and Weber, carries preoccupational dangers: Popper's elitist rooting out of 'pseudo-science', Weber's hard-working obsessive com mitment to science. See Agassi's Weberian gloss on the social psychology of science in his provocative 'picture of the scientist as maniac' (437).

Taschenbuch. Condizione: Neu. Neuware - This book is the outcome of the successful NATO Advanced Study Institute on Pattern Recognition Theory and Applications, held at St. Anne's College, Oxford, in April 1981., The aim of the meeting was to review the recent advances in the theory of pattern recognition and to assess its current and future practical potential. The theme of the Institute - the decision making aspects of pattern recognition with the emphasis on the novel hybrid approaches - and its scope - a high level tutorial coverage of pattern recognition methodologies counterpointed with contrib uted papers on advanced theoretical topics and applications - are faithfully reflected by the volume. The material is divided into five sections: 1. Methodology 2. Image Understanding and Interpretation 3. Medical Applications 4. Speech Processing and Other Applications 5. Panel Discussions. The first section covers a broad spectrum of pattern recognition methodologies, including geometric, statistical, fuzzy set, syntactic, graph-theoretic and hybrid approaches. Its cove,r age of hybrid methods places the volume in a unique position among existing books on pattern recognition. The second section provides an extensive treatment of the topical problem of image understanding from both the artificial intelligence and pattern recognition points of view. The two application sections demonstrate the usefulness of the novel methodologies in traditional pattern 'recognition application areas. They address the problems of hardware/software implementation and of algorithm robustness, flexibility and general reliability. The final section reports on a panel discussion held during the Institute.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Early embryonic loss is a continuing social and economic global problem. In human populations the estimates of interruptions early in pregnancy range from 35-60%. In animal husbandry (swine, ruminants) fully 30% of pregnancies fail to survive early events of gestation. The futility associated with this persistant high risk is even more unsettling because of advances made in assisted reproductive technology which, although this very selective methodology has added to our knowledge of embryo-endometrial interactions, has resulted in a birth rate of only 14%. These studies have instigated comparisons of the live relative contributions of the embryo and the uterus to the outcome of pregnancy. These analyses have shown that we have learned significantly less about the role of the uterus in deciding the outcome of either natural or assisted pregnancies. In 1979 a quotation by George Corner was used to set the tone of a meeting that was devoted to discussion of the cellular and molecular aspects of implantation. In spite of the proliferation in research activity which occurred in the following 15 years our real understanding of the embryo transfer process has fallen short of our expectations. We use the Corner quotation, once again, to preface this symposium so that we may recall that the fundamental nature of the process which regulates embryo-endometrial interactions still escapes us. 415 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -De Lange suggests a new contextually linked building block model to develop theories of the firm in the field of strategy and organizations. Using this approach, she proposes two models: one that is a realistic American version and another that is a futuristic sustainable model. Both are new networked models that integrate current theories; a review of international corporate governance supports the sustainable firm that solves problems of the current one. Through a revised theoretical lens, the book answers a provocative question surrounding modern corporate America: Who wields the power In this investigative look at the institutional mechanisms behind who is truly running the show, Cliques and Capitalism seeks to not only explain why the current corporate system fails to function well, but also offers solutions for improved corporate governance through a new sustainable model. 256 pp. Englisch.
