Taschenbuch. Condizione: Neu. Neuware -During the course of the developnent of most areas of scien tific research certain events occur that serve to bring a particular area into focus. We feel that this symposilHll volume serves that role with regard to the study of the reproductive biology of amphib ians. The collection of vnrk…s contained in this volume provides an excellent review of a diversity of past contributions to this field of investigation and brings together in one volume the major ap proaches that have been utilized to study amphibian reproductive biology. The work emphasizes recently-completed studies and therefore can be considered to be an up-to-date account of the field. Equally signif icant, however, the contributors to this volume have excelled in pointing out directions for future research that will be of im mense value in integrating the component parts of reproductive bi ology, i.e., genetics, developnental biology, physiology, behavior, and ecology, into an eVOlutionary framework. 488 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Biomedical Ethics Reviews is an annual publication designed to review and update the literature on issues of central importance in bioethics today. Ordinarily, more than one topic is discussed in each volume of Biomedical Ethics Re…views. This year, however, we have decided to devote the entire volume of Biomedical Ethics Reviews: 1988 to disussion of one topic, namely, AIDS. The ra tionale for this decision should be clear: AIDS is arguably the most serious public health threat facing our nation today, and the char acter of the disease is such that it creates special problems for ethicists, philosophers, theologians, educators, jurists, health care professionals, and politicians. Indeed, the questions that AIDS gives rise to are so numerous and complex that no one text could hope to treat them exhaustively. Still, if it is impossible, in anyone text, to deal with all of the perplexing difficulties that AIDS generates, it nevertheless remains true that each addition to the AIDS literature contributes to our collective knowledge, and in so doing, brings us one step closer to resolving at least some of the problems associated with the disease. We believe that the articles included in the present volume of Biomedical Ethics Reviews serve this purpose admirably, and we hope the reader will agree. James M. Humber Robert F. Almeder vii Contributors Ronald Carson - Medical Humanities Institute, University of Texas Medical Branch, Galveston, Texas David J. 184 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The series of volumes entitled Biological Responses in Cancer provides information on approaches through which the interaction between neoplas tic and normal cells may be modified. Topics discussed in various volumes include immuno…logical and host defense systems, control mechanisms of cell and population growth, cell differentiation, and cell transformation. This volume is specifically concerned with various aspects of cell interactions and regulation within heterogeneous tumor cell populations, and their role in tumor progression and metastasis. Knowledge in this area is likely to provide new leads toward the exploitation of novel cellular sites and mech anisms in the development of new types of therapies of cancer. Several topics are discussed within these general areas of consideration. The possibly unique characteristics and mechanisms of tumor vascularization and the potential sites of interference with angiogenesis that might have therapeutic impli cations are critically evaluated. Tumor cell-normal tissue interactions in volved in different phases of the growth and metastatic processes are dis cussed in two chapters dealing with mechanisms of tumor invasion and with the role of collagen in mammary tumor growth; here again potential leads are identified that may be exploited toward the development of new thera peutic approaches. The evolution of phenotypic diversity as a phenomenon complicating the biology of tumor metastasis and consequently affecting the opportunities offered by chemotherapy is also critically considered. 276 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -An overall view of the cancer problem and development of cancer chemothera 231 peutic biosynthetic products to February 1976 was presented in Volume 1. In the short time that has elapsed since the preparation of Volume 1, several v…ery stimulating advances in application of biosynthetic cancer chemotherapeutic drugs in cancer treatment have been reported. At the May 1976 meeting (in Toronto) of the American Association for Cancer Research, a Sloan-Kettering research group summarized an improved treatment of human neuroblastoma using a combination of vincristine, cytoxan, trifluorothymidine, and papaverine. In the same period other clinical groups described significant advances in the cancer chemotherapeutic treatment of human breast cancer and oat cell carcinoma of the lung. Each of these newer advances in cancer treatment was based on combinations of biosynthetic and synthetic cancer chemotherapeutic drugs. Certainly, further examination of the antineoplastic biosynthetic agents summarized in this volume and the vast number yet to be discovered will eventually provide the means for controllil).g and/or curing the various types of human cancer. 164 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The short period since the publication of Volume 1 of Methods in Membrane Biology has been a time of momentous progress. Calorimetry, electron spin and nuclear magnetic resonance, X-ray diffraction, and freeze-cleavage electron mic…roscopy, reinforced by biochemical analyses and enzymatic studies, have led to universal acceptance of a generalized membrane model. All membrane biologists would agree that a major element of all biological membranes is a bilayer of phospholipids which, in some instances, also contains other lipids, notably sterols and glycolipids. The fatty acid com position of the lipids of most membranes is such that the lipids are above their transition temperatures in their normal environment so that the bilayer is fluid. The microviscosity of the fatty acyl groups decreases pro gressively down the chain so that, at the hydrocarbon interior of the bilayer, the lipid phase has a viscosity approximating that of olive oil at room temperature. As a consequence of this membrane fluidity, a phospholipid molecule is very mobile within the plane of the membrane (moving a distance of about 1-2 fLm in 1 s) but the movement of a phospholipid molecule from one side of the membrane bilayer to the other (flip-flop) is very slow. The lipid bilayer is an essentially inert and rather impermeable struc ture, as shown by many studies with model systems. Proteins, of course, provide the catalytic components of the membranes. as well as playing a significant structural role. 324 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Electronic Prope~ties Information Cente~ has developed the Data Table as a compilation of the most ~eliable info~mation available fo~ the physical, c~ystallog~aphic, mechanical, thermal, elect~onic, magnetic and optical p~ope~t…ies of a given mate~ial. Data Tables forme~ly se~ved as an int~oduction to the g~aphic data compilations on the mate~ial published by the Elect~onic ~ope~ties Information Cente~, EPIC, as Data Sheets. Although the Data Sheets we~e p~incipally concerned, according to the scope of the Cente~, with electronic and optical data, it is believed that data cove~ing the complete p~ope~ty spect~um, is of the f~st impo~tance to eve~y scientist and engineer, whateve~ his information requi~ements. The enthusiastic ~eception of these Data Tables has confi~med this opinion and increasing requests fo~ this highly selective type of information ~esulted in the publication of volume 2 in this se~ies, 'III-V Semiconducting Compounds' in 1971 and 'G~oup IV Semiconducting Compounds', also in 1971. Recent inte~est in the device applications of the te~n~y semiconducto~s, led to the compilation of these Data Tables on the III-V Te~n~y Semiconducting Compounds. The majo~ problem in this type of selective data compilation on a semiconducting mate~ial, lies in the mate~ial specifications. Prope~ties may va~y so widely with doping, c~stallinity, defects, geometric forms and the othe~ pa~amete~s of p~epa~ation, that any attempts at comparison normally fail. On this basis, we have consistently attempted to give the p~epa~ation methods, ca~rier concent~ations, and physical form. 68 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume, the second in the Methods in Pharmacology series, contains some of the physical methods which either have been or could be applied to pharmaco logical problems. A major emphasis has been placed on spectroscopic techniq…ues, particularly those, such as optical rotatory dispersion and circular dichroism, fluorescence spectroscopy, magnetic resonance spectroscopy, ultraviolet absorption spectroscopy, stopped flow and relaxation spectrometry, Mossbauer spectroscopy, light scatter and x-ray crystallography, that can be used to study drug interactions with biological systems at a molecular level. Although phosphorescence spectro scopy and oscillographic polarography can also be used to study drug interactions, their main usefulness is in the detection and estimation of drugs and their meta bolities in body tissues and fluids. Mass spectrometry is a powerful tool for study ing the metabolism of drugs as well as for detecting abnormal endogenous metabolites in the body. Finally, heatburst microcalorimetry is a non spectroscopic technique that can be used to study how drugs and other ligands interact with biological macromolecules. Each chapter contains a brief introduction to the theoretical basis for each technique as well as a description of the instrumentation involved. This is followed by a section describing the application of the technique to pharmacological prob lems. Where these are not available, examples have been drawn from the other life sciences. In a final section, some further applications of each technique to problems in pharmacology are suggested. 512 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -As the nature of the field of environment-behavior relations is interdis ciplinary, the collaboration of three persons of diverse professional backgrounds in writing this book is therefore not surprising. This col laboration starte…d in 1972 with the offering of a graduate seminar 'Envi ronment, Behavior, and Design Evaluation' at the University of Massa chusetts. Several research projects dealing with design evaluation which have been conducted at the University are also included as case studies in this book (Chapter III): the ELEMR study and the Visitor Center study. Two of the authors have worked as part of the instructional team in the seminar, and all of the authors have participated in varying degrees in the ELEMR Project. The authors' backgrounds in design, psychology, and landscape architecture suggest, by example, that professionals with diverse backgrounds but a common interest in environment-behavior problems can indeed learn to communicate and to collaborate. Since design evaluation is a new field and very little specific litera ture on the subject exists to date, we hope this book fills a current need. 236 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A 'Festschrift' volume fulfils a more far-reaching purpose than the laudatory one. It shows how science develops as a result of the activities - scientific and organizational - of an individual person. Scientific achievement cannot… be subjected to the very refined measurement techniques of science itself, but there is a continuous mutual evaluation among scientists which manifests itself through refereeing, literature citation and dedicatory volumes like the present one. Near and distant associates of Per-Olov Lowdin were enthusiastic about the idea of a tribute to him in the form of a collection of scientific papers on the occasion of his sixtieth birthday. Monographs and journals have fairly well-defined readerships. This book is directed to a wider group of scientists. It presents reviews of areas where Lowdin's work has influenced the development as well as research papers with original results. We feel that it can serve as a source on the current status of the quantum theory of matter for scientists in neighbouring fields. It might also provide stimulus for renewed scientific efforts among scientists turned administrators and will certainly be relevant for teachers and students of quantum theory. 608 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Volume V deals with the problems of turnover in the nervous system. 'Turnover' is defined in different ways, and the term is used in different contexts. It is used rather broadly in the present volume, and intentionally so. The tur…nover of macromolecules is only one aspect; here 'turnover' in dicates the simultaneous and coordinated formation and breakdown of macromolecular species. The complexities of cerebral protein turnover are shown in a separate chapter dealing with the synthesis of proteins, in another on breakdown, and in still another on the relationship of these two (showing how the two halves of turnover are controlled). The fact that most likely the two halves of protein turnover, synthesis and breakdown, are separated spatially and the mechanisms involved are different further emphasizes the complexity of macromolecular turnover. 'Turnover' is used in a different context when the turnover of a cycle is discussed; but here again a number of complex metabolic reactions have to be interrelated and controlled; some such cycles are discussed briefly in this volume, additional cycles have been discussed with metabolism, and some cycles still await elucidation or discovery. 480 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Frequently attempts to design experiments utilizing the methodology de scribed in articles in trade journals can be frustrating. Description of procedures, because of space constraints, are not always complete. The present volume a…ttempts to bring together in one reference source many of the techniques which are utilized in the study of the kidney. It provides a thorough compendium of research tools, framed by the critical analysis of the theoretical background of renal physiology, biochemistry, and pharmacology discussed in Volume 4A. Some areas previously dealt with are not covered from a methodological point of view since adequate information does exist elsewhere (e.g., methods of whole kidney ATPase isolation). Since drugs acting on the kidney may alter not only functional but anatomical integrity, a chapter on the preparation of tissue for morphological studies has been included. The important developments in analy sis of minute (ultramicro) quantities of tissue and biological fluids, as well as methodological advances in studies of the isolated kidney, are thoroughly covered. It is my hope that investigators, research fellows, and graduate students will benefit from the information contained in this volume and that, together with its companion tome, it will be a ready reference for the renal physiologist, the renal pharmacologist, and the nephrologist. The contributors have provided painstaking descriptions and, when re quired, mathematical analyses of the techniques described herein. I wish to thank all of them for their enthusiasm and the excellence of their contributions. 416 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -(Written for the original Russian edition) Out of all the functional groups of protein molecules that be long to the side chains of amino acid residues, the sulfhydryl or thiol (SH) groups of cysteine residues and the disulfide (S-…S) groups of cystine have for long attracted particular attention from chemists and biochemists. This is due, on the one hand, to the high chemical reactivity of these groups, which enter into many, and often very characteristic and selective, reactions with several types of compound. On the other hand, this attention is connected with the great significance of SH and S-S groups for the specific functions of a number of enzymes, hormones, and other biological ly active proteins, and consequently for the normal course of many physiological processes. The varied functions of sulfhydryl and disulfide groups in en zymes are particularly interesting; their role can consist of bind ing substrates and cofactors, in direct participation in the catalytic act, or in maintaining (in ways not so far sufficiently studied) the native, catalytically active conformation of the protein. It is entirely natural that the detailed study of the chemical behavior and biological role of these sulfur-containing groups in proteins (and in such low-molecular cofactors as glutathione, co enzyme A, lipoiC acid, etc. ) has, in addition to its academic, gen eral biological interest, great Significance for many applied branches of medicine and biology (toxicology, radiobiology, diagnostics and therapeutics, biochemical engineering, plant growing, etc. ). 288 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In less than 40 years teratology has grown from a little known discipline concerned with studies on the effects of a few physical and chemical stresses on developing fish, amphibians, and birds, to a discipline embracing a vast acc…umulation of literature on experimental studies in many animal forms and the results of intensive scrutiny of human development under varied conditions, as well. Emphasis has shifted from preoccupation with descrip tions of anatomical defects to concern about subtle and interacting causative factors, to searches for the early reactions to these at the cellular and subcellu lar levels, and to identification of abnormality in the chemical, the functional, and the ultrastructural realms. These changes in orientation have quite naturally made necessary the recruitment of concepts, methods, and expertise from other disciplines. Hence the foundations of teratology, which once were largely morphological, have extended into genetics, biochemistry, molecular biology, reproductive physiology, epidemiology, and several aspects of veteri nary and clinical medicine. It is not surprising that a student or new investigator approaching the field of teratology may feel some dismay when confronted with the confusing array of cross-disciplinary concepts and principles it encompasses today. One of the aims of this work is to introduce what the editors believe is a logical thread of continuity into a field that may be regarded by some as a welter of disordered information. 492 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Fifth International Cryogenic Materials Conference (ICMC) was held in Colorado Springs, Colorado in collaboration with the Cryogenic Engineering Conference (CEC) on August 15-19, 1983. The growth and success of the joint confer…ences is a result of their complementary program and close cooperation. Materials remain a challenge in the application of cryogenic technology and sometimes, as in the case of superconductors, are the driving force for the technology. The association of materials and cryogenic engineers increases their awareness of recent research in their respective fi. elds and influences the course of future research and applications. Many contributed to the success of the 1983 conference: E. W. Collings of Battelle Memorial Institute was the ICMC Confer ence Chairman; M. Suenaga of Brookhaven National Laboratories, the ICMC Program Chairman; and L. L. Sparks of the National Bureau of Standards, the ICMC Local Arrangements Chairman. J. M. Wells and A. I. Braginski of Westinghouse R & D Center, G. Hartwig of the Nuclear Research Center of Karlsruhe, and K. T. Hartwig of the University of Wisconsin assisted the Program Chairman in metallic metals, superconducting materials, nonmetallic materials, and cryo physical properties, respectively. Excellent conference management was provided by Centennial Conferences. We especially thank M. Stieg, who coordinated the preparation of the papers for this volume. The CEC Board, especially their conference chairman, C. D. Henning of Lawrence Livermore National Laboratories, contributed very substan tially to conference planning and implementation. 1024 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -In Reproduction, Technology, and Rights, philosophers and ethicists debate the central moral issues and problems raised by today's revolution in reproductive technology. Leading issues discussed include the ethics of paternal oblig…ations to children, the place of in vitro fertilization in the allocation of health care resources, and the ethical implications of such new technologies as blastomere separation and cloning. Also considered are how parents and society should respond to knowledge gained from prenatal testing and whether or not the right to abort should relieve men of the duty to support unwanted children. Reproduction, Technology, and Rights illuminates the moral and ethical choices that our society faces because of advances in reproductive technology and helps to make those decisions better informed. 172 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The present volume is the second in the author's series of three dealing with abstract algebra. For an understanding of this volume a certain familiarity with the basic concepts treated in Volume I: groups, rings, fields, homomorph…isms, is presupposed. However, we have tried to make this account of linear algebra independent of a detailed knowledge of our first volume. References to specific results are given occasionally but some of the fundamental concepts needed have been treated again. In short, it is hoped that this volume can be read with complete understanding by any student who is mathematically sufficiently mature and who has a familiarity with the standard notions of modern algebra. Our point of view in the present volume is basically the abstract conceptual one. However, from time to time we have deviated somewhat from this. Occasionally formal calculational methods yield sharper results. Moreover, the results of linear algebra are not an end in themselves but are essentialtools for use in other branches of mathematics and its applications. It is therefore useful to have at hand methods which are constructive and which can be applied in numerical problems. These methods sometimes necessitate a somewhat lengthier discussion but we have felt that their presentation is justified on the grounds indicated. A stu dent well versed in abstract algebra will undoubtedly observe short cuts. Some of these have been indicated in footnotes. We have included a large number of exercises in the text. 296 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This English edition could serve as a text for a first year graduate course on differential geometry, as did for a long time the Chicago Notes of Chern mentioned in the Preface to the German Edition. Suitable references for ordin a…ry differential equations are Hurewicz, W. Lectures on ordinary differential equations. MIT Press, Cambridge, Mass., 1958, and for the topology of surfaces: Massey, Algebraic Topology, Springer-Verlag, New York, 1977. Upon David Hoffman fell the difficult task of transforming the tightly constructed German text into one which would mesh well with the more relaxed format of the Graduate Texts in Mathematics series. There are some e1aborations and several new figures have been added. I trust that the merits of the German edition have survived whereas at the same time the efforts of David helped to elucidate the general conception of the Course where we tried to put Geometry before Formalism without giving up mathematical rigour. 1 wish to thank David for his work and his enthusiasm during the whole period of our collaboration. At the same time I would like to commend the editors of Springer-Verlag for their patience and good advice. Bonn Wilhelm Klingenberg June,1977 vii From the Preface to the German Edition This book has its origins in a one-semester course in differential geometry which 1 have given many times at Gottingen, Mainz, and Bonn. 196 pp. Englisch.

Neuware -Electronic funds transfer (EFT) systems include a wide range of computer-based payment systems and sources that substitute electronic and digital transfers for movements of cash and paper checks. A few years ago some people were predic…t ing that EFT would replace paper money and coins entirely and that we would soon be a 'checkless' and' 'cashless' society. Such sweeping changes have not occurred, but a slower evolution is clearly underway. Although checks, cur rency, and coin are likely to be here for many years to come, EFT is becoming an established part of our worldwide payment transfer system, and the implications and consequences of this technology are real. They include: ¿ Alterations in personal finance and in the process of purchasing and paying for consumer goods and services. ¿ Changes in the structure of financial and retail organizations and their mode of interaction in the marketplace. ¿ Modifications in the flow of funds in our society and in the interactions among economic institutions. ¿ Alterations in the prospects for invasion of personal privacy, perpetration of fraud and theft, and violation of antitrust regulations. ¿ Changes in the regulatory and competitive balance among the numerous financial institutions in the United States. Such alterations foretell important impacts on people and society. Benefits are forthcoming, but the costs will also be real.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 328 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Growth, as we conceive it, is the study of change in an organism not yet mature. Differential growth creates form: external form through growth rates which vary from one part of the body to another and one tissue to another; and intern…al form through the series of time-entrained events which build up in each cell the special ized complexity of its particular function. We make no distinction, then, between growth and development, and if we have not included accounts of differentiation it is simply because we had to draw a quite arbitrary line somewhere. It is only rather recently that those involved in pediatrics and child health have come to realize that growth is the basic science peculiar to their art. It is a science which uses and incorporates the traditional disciplines of anatomy, physiology, biophysics, biochemistry, and biology. It is indeed apart ofbiology, and the study of human growth is a part of the curriculum of the rejuvenated science of Human Biology. What growth is not is aseries of charts of height and weight. Growth standards are useful and necessary, and their construction is by no means void of intellectualchallenge. Theyare a basic instrument in pediatric epidemiology. But they do not appear in this book, any more than clinical accounts of growth disorders. This appears to be the first large handbook-in three volumes-devoted to Human Growth. Smaller textbooks on the subject began to appear in the late nineteenth century, some written by pediatricians and some by anthropologists.Libri GmbH, Europaallee 1, 36244 Bad Hersfeld 656 pp. Englisch.

Neuware -Continuum Mechanics of Anisotropic Materials(CMAM) presents an entirely new and unique development of material anisotropy in the context of an appropriate selection and organization of continuum mechanics topics. These features will distingui…sh this continuum mechanics book from other books on this subject. Textbooks on continuum mechanics are widely employed in engineering education, however, none of them deal specifically with anisotropy in materials. For the audience of Biomedical, Chemical and Civil Engineering students, these materials will be dealt with more frequently and greater accuracy in their analysis will be desired. Continuum Mechanics of Anisotropic Materials' author has beena leaderin the field of developing new approaches for the understanding of anisotropic materials.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 440 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Those who are familiar with the two volumes of The Year in Endocrinology may, at first glance, fail to recognize their relationship to the present volume, Contemporary Endocrinology. The name is different and the cover design different…, but nonetheless the admonition against judging a book by its cover is very well taken in this instance. In fact, Contemporary Endocrinology is not only the direct linear descendant of The Year in Endocrinology, it is a purposeful clone thereof-the topics are unchanged, the talented group of authors is unchanged, and most importantly, both the objective of the work and the manner in which that objective is approached are unchanged. The objective is, of course, to assist the reader in maintaining currency with respect to important developments, both basic and clinical, in the major areas of endocrinology. We are all much too familiar, unfortunately, with the difficulty of maintaining currency these days. Our approach to dealing with the informational inflation that we are suffering is similar to that used by economists in dealing with monetary inflation, that is, to increase interest. This we have attempted to do by providing for the reader an easy-to-read group of essays in which advances in individual areas of endocrinology are re viewed broadly, synthesized, and placed into perspective by a group of authors who are authorities in their individual fields. They serve, not as guest artists, but as members of a stable Editorial Board that provides continuity by contributing to successive volumes.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 420 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -The distinction between molecular immunology and immunobiology is neces sarily arbitrary. The most rapid progress is usually made in the blurred area between the two, when the chemist is aware of the full significance of the biological… problems, and the biologist is alert to the contribution that a knowl edge of molecular structure can be made to their solution. The range of scientific disciplines able to contribute to research in immunology, which this approach brings, is reflected in the present volume. Protein chemists worked out the arrangement of the polypeptide chains and the amino acid sequences of antibodies and X-ray crystallographers the three dimensional structure, but more precise definition of the amino acid side chain positions in the combining site is required for an understanding of the subtleties of antibody specificity. That this can be achieved with physical techniques such as nuclear magnetic resonance has been shown by R. A. Dwek, and in his chapter he summarizes these results with a minimum of technical detail. The immune response has been shown to be dependent on complex cellular interactions and further progress will be facilitated by investigation of the molecular basis of these interactions. This necessitates study of the structure and organization of the molecules in the surfaces of lymphocytes and other cells.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 272 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -This is the first book that is devoted entirely to a discussion of the effects on drinking behavior of sensory stimulation of the tongue and mouth. As Blass and Hall (J 976) have recently pointed out, there has been an overrejection of… the emphasis by Cannon (1932) and Hull (1943) on the peripheral origins (e. g. , dry mouth, empty stomach) of the control of ingestive behavior. Thus most present-day investigators of drinking behavior have been concentrat ing on central mechanisms of control, to the neglect of the periphery. In this volume we have attempted to bring together much of the pertinent 'peripheral' literature through originally written chapters that are concerned with the role of orosensory factors in the mediation of drinking and licking. Postingestive effects of fluids receive little attention. Indeed, two chapters deal with consummatory licking in the absence of intake of fluids. A good understanding of the consequences of orosensory stimulation on licking and drinking behavior requires insight into the functional anatomy of the tongue and mouth, the characteristics of the licking response and the problem of recording of licking behavior. Several chapters deal with these subjects. It has not only been a pleasure but also a privilege to edit this volume. We have learned much from the expert treatment of the different aspects of licking and drinking behavior by the chapters' authors.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 440 pp. Englisch.

Neuware -In recent years, epigenetic approaches to existing scientific problems have offered many new and exciting perspectives. This book focuses on epigenetic approaches to study asthma and allergy research. The authors briefly review cellula…r factors, immune signaling, and inflammatory pathways in allergy and asthma, as well as genetic influences in the pathogenesis of atopic disorders. Diseases that have been clearly linked to an epigenetic dysregulation will be discussed, as well as the role of epigenetics in the origin of complex diseases. The authors will examine the impact of environment factors in the predisposition to atopic disorders, and they will also describe the major unanswered questions and future perspectives of an exciting new field that studies allergic diseases from the epigenetic point of view.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 72 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -The science and art of crystal growing continue to flourish; even with increasing understanding of the science, 'feel' and skill continue to play their vital part, as was so clearly evidenced at the recent Boston International Conferen…ce on Crystal Growth. The aim of this volume, the same as that of the first, is to try to improve understanding by providing detailed discussions of crystal growth techniques and problems that arise with them. The published paper in the specialized literature is too limited a vehicle, by convention and by editorial pressure on length, to discuss matters in detail, yet it is in the small details born of experience that vital information can often lie concealed. A major aim of this series, therefore, has been to encourage contributors to describe rather fully what has been achieved in their special fields. The next volume of this series is now well underway and plans for Volume 4 are advanced. If you, the reader, feel that some important aspect of crystal growth is being unjustifiably neglected, perhaps you should consider offering a contribution! And even if you do not wish to do that, please do offer criticism-preferably constructive. I hope that the present volume will prove as useful and interesting to crystal growers as apparently did the first volume of the series; certainly the warm commendations that that volume has elicited were a great encouragement for the present work. Finally it is a pleasure to thank Standard Telecommunication Laboratories for its continuing support.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 204 pp. Englisch.
