Neuware -Donald Kennedy President, Stanjord University Alnwst exactly a dozen years elapsed between the time I set aside (I thought temporarily!J my own interest in crustacean nervous systems and the arrival of an invitation from Konrad Wiese to participate in this symposium. The intervening years have plainly been productive ones for the field; indeed, I can only hope that there is no causal connection between its properity and my absence. Discontinuous contact with an intellectual venture, whatever disappointments it may present. does oifer one virtue; it provides a nwre dramatic. alnwst stroboscopic view of progress. To the lapsed practitioner, the rate of advance in crustacean neurobiology over the decade seems remarkable; equally remarkable is the number of able young researchers. many of them the scientific progeny of my colleagues from the 'sixties' and 'seventies' . How to summarize the changes they have wrought Those of us who began working with crustacean nervous systems thirty years 090 or so were attracted by several features. First of alt there was a limited nwtor system with readily identifiable neurons. It was diJft.cult to look at those old methylene blue stains of Retzius and not want to do an experiment immediately! Kees Wiersma ojten did, and it was he who nwst persuasively called our attention to the advantages oifered by neuronal parsinwny in combination with stereotyped motor output patterning. Ted Bullock exploited these features in his elegant early experiments on cardiac ganglia.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 588 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -In spite of all emphasis on objectivity, a scientific discipline needs for its development outstanding research workers with exceptional personal qualities. A scientist with these qualities is honoured here, on the occasion of his 70th birthday, by his pupils, friends and colleagues: Arthur Linder is respected as a researcher, advisor and teacher in the field of Applied Statistics. Professor Dr. Dr. h. c. A. Linder has demonstrated the utility of statistical methods in science and technology; these are recognised today as being essen tial for an objective evaluation of data. His contacts with Sir R. A. Fisher, C. 1. Bliss, G. M. Cox, W. G. Cochran, P. C. Mahalanobis and many other ex perts, have helped him to achieve his almost legendary authority on sampling and on the evaluation of statistical data. Linder has won many friends and adherents to the cause of Biometry, Econometry and Technometry, firstly through his teaching activity at the universities of Berne, Geneva and Lausanne and the Swiss Federal Institute of Technology in Zurich, and as visiting lecturer at the Indian Statistical Institute, the International Statistical Education Centre in Calcutta, the Uni versity of North Carolina and the University of Natal in Durban, secondly through his contributions to the literature as author of the monographs 'Sta tistische Methoden' and 'Planen und Auswerten von Versuchen', as editor of METRIKA and co-editor of other journals, and thirdly through his active collaboration in the founding of The Biometric Society, to the presidency ofSpringer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 264 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Ten years ago interest in leukocyte chemotaxis was restricted to a relatively small group of scientists whose interests were quite circumscribed. In the past decade both the number of workers and their publications has grown at some thing approaching an exponential rate and, more importantly, the field has gradually expanded to encompass a large number of diverse areas (mediators, receptors, cell effector mechanisms, regulatory factors, etc.). It is now apparent that leukocytes are particularly useful for studies of the locomotory behavior of all cell types and of mechanisms controlling cell movement and orientation. Chemotactic factors, once discovered as substan ces able to induce directional migration in leukocytes, are now recognized as potent stimulators of a variety of cell functions. Based on our knowledge in the field of basic research in leuko cyte chemotaxis, clinical observations in combination with ex perimental studies in vivo have provided new insights into the role of leukocyte-mediator interactions. The recognition that a specific interaction between chemotactic factor and leukocyte can lead to a multitude of cellular responses and products has opened up a broad area of study. The diversity of contributions to this volume based on a conference which was held in May 1982 in Gersau, Switzerland, reflects this development and demonstra tes that leukocyte chemotaxis continues to be an area of fasci nating and highly active research.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 444 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -The basic knowledge of cell biology and molecular genetics in oncology is increasingly attracting the interest of clinical oncologists and is close to reaching a helpful application at the bedside. At present, it seems clear that the solution of the cancer problem lies within the comprehension of the intimate mechanisms leading to cell transformation and tumor progression as weIl as of the cancer-host relationship. According to this rationale every achievement in this context could drastically improve both diagnosis and therapy of neoplastic diseases. This={)ook represents the proceedings of the International Conference o~ Cancer: Biological Mechanisms and Clinical Applications, held in Rome on November 16-18, 1992. The meeting was organized by the Centro di Ricerche Oncologiche 'Giovanni XXIII' of the Catholic University of Rome and the Consorzio Mario Negri Sud of S. M. Imbaro in collaboration with other colleagues from the Universities of Napoli and Bologna. As organizers and pmticipants to the Conference we think the meeting was a success, as was confirmed by the great interest raised in scientific and academic circles. The book collects contributions from leading scientists in all oncological m eas ranging from molecular biology to immunology, diagnosis and therapy. The papers are organized into four sections: I - Molecular aspects of cell transformation and growth; II - Membrane receptors and signal transduction; III - Models for new therapeutical strategies; IV - Clinical Applications, following the strategy that chm acterized the entire meeting: from molecule to bedside.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 448 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -The theory of the Lebesgue integral is still considered as a difficult theory, no matter whether it is based the concept of measure or introduced by other methods. The primary aim of this book is to give an approach which would be as intelligible and lucid as possible. Our definition, produced in Chapter I, requires for its background only a little of the theory of absolutely convergent series so that it is understandable for students of the first undergraduate course. Nevertheless, it yields the Lebesgue integral in its full generality and, moreover, extends automatically to the Bochner integral (by replacing real coefficients of series by elements of a Banach space). It seems that our approach is simple enough as to eliminate the less useful Riemann integration theory from regular mathematics courses. Intuitively, the difference between various approaches to integration may be brought out by the following story on shoemakers. A piece of leather, like in Figure 1, is given. The task consists in measuring its area. There are three shoemakers and each of them solves the task in his own way. A B Fig. 1 The shoemaker R. divides the leather into a finite number of vertical strips and considers the strips approximately as rectangles. The sum of areas of all rectangles is taken for an approximate area of the leather (Figure 2). If he is not satisfied with the obtained exactitude, he repeats the whole procedure, by dividing the leather into thinner strips.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 248 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -This paper is a largely expository account of the theory of p x p matrix polyno mials associated with Hermitian block Toeplitz matrices and some related problems of interpolation and extension. Perhaps the main novelty is the use of reproducing kernel Pontryagin spaces to develop parts of the theory in what hopefully the reader will regard as a reasonably lucid way. The topics under discussion are presented in a series of short sections, the headings of which give a pretty good idea of the overall contents of the paper. The theory is a rich one and the present paper in spite of its length is far from complete. The author hopes to fill in some of the gaps in future publications. The story begins with a given sequence h_n' . , hn of p x p matrices with h-i = hj for j = 0, . , n. We let k = O, . ,n, (1.1) denote the Hermitian block Toeplitz matrix based on ho, . , hk and shall denote its 1 inverse H k by (k)] k [ r = . k = O, . ,n, (1.2) k II} .

Neuware -Whilst improperly posed problems appear in several branches of applied and pure mathematics, this conference concentrated mainly on the practical treatment of ill posedness. The participants came from 12 countries. The interchange of ideas reflected the spectrum of questions arising in connection with the subject of the conference, where currently progresses in research are made. This volume contains 17 papers presented at the con ference. Focal points in the programme were: Problems of regularisation, parameter identification, free boundary and inverse problems in differential equations and inte gral equations of the first kind. Problems, which appear in science, in technical fields and in medicine are dis cussed as well as general operator equations. In a jOint discussion, several open problems have been worked out which are collected at the end of the volume. The editor's thanks go to all contributors and parti cipants who made the conference a success; to the manage ment of the institute with its unique atmosphere; to the Birkhauser Verlag for the possibility to publish the vo lume in the well-known ISNM series; to Dr. P. Jochum (Mlin chen) for assistance in organization and to Mrs. Chr.

Taschenbuch. Condición: Neu. Neuware -Volume 39 of 'Progress in Drug Research' contains eight reviews and the various indexes which facilitate its use and establish the con nection with the previous volumes. The articles in this volume deal with polyamines as tumor markers; the histamine (H3)-receptor and its role as a general regulatory system; with cytokines as immunosti mulants and immunosuppressants as well as potential anticancer agents; with fibrinolysis and clinical use of thrombolytic agents; and with catechol O-methyltransferase and its inhibitors, which are of potential interest in the treatment of Parkinson's disease. An exten sive review on antihistamines (HI) provides an excellent survey of this area in drug research. In the 32 years that 'Progress in Drug Research' has existed, the Editor has enjoyed the valuable help and advice of many colleagues. Readers, the authors of the reviews, and, last but not least, the review ers have all contributed greatly to the success of the series. Although the comments received so far have generally been favorable, it is nevertheless necessary to analyze and to reassess the current position and the future direction of such a review series.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 408 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Methods in protein sequence analysis constitute important fields in rapid progress. We have experienced a continuous increase in analytical sensitivity coupled with decreases in time necessary for purification and analysis. Several generations of sequencers, liquid/solid/gas-phase, have passed by and returned in other shapes during just over two decades. Similarly, the introduction of HPLC permitted an enormous leap forward in this as in other fields of biochemistry, and we now start to see new major advances in purification/analysis through capillary electrophoresis. Furthermore, progress in the field of mass spectrometry has matched that in chemical analysis and we witness continuous development, now emphasizing ion spray and other mass spectrometric approaches. In short, protein analysis has progressed in line with other developments in modern science and constitutes an indispensable, integral part of present-day molecular biology. Even the available molecular tools, in the form of proteases with different specificities, have increased in number, although we still have far to go to reach an array of 'restriction proteases' like the sets of nucleases available to the molecular geneticist. Of course, conferences have been devoted to protein sequence analysis, in particular the MPSA (Methods in Protein Sequence Analysis) series, of which the 8th conference took place in Kiruna, Sweden, July 1-6 1990. Again, we witnessed much progress, saw new instruments, and experienced further interpretational insights into protein mechanisms and functions.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 412 pp. Englisch.

Neuware -The Eleventh International Transport Theory Conference and Symposium in honor of the sixty-fifth birthday of Kenneth Case and the sixtieth birthday of Paul Zweifel was held in Blacksburg, Virginia, during May 22-26, 1989, on the campus of Virginia Polytechnic Institute and State University (Virginia Tech). This volume consists of a selection of the invited papers delivered at the Conference, and represents a cross section of the research currently being carried out in the field of transport theory. The volume is divided into two sections. The Symposium lectures are intended each to summarize an important aspect of transport theory, as well as to present timely new results of the author's research interest. The Conference lectures are contributions of each author on his current research. As has been the custom in this series of conferences, each lecturer was invited to participate by the organizing committee of the Conference: W. Greenberg, Virginia Tech, chairman; V. Boffi, Universita di Firenze; N. Corngold, California Institute of Technology; B. Ganapol, University of Arizona; N. McCormick, University of Washington; P. Nelson, Texas Tech; G. Pomraning, University of California, Los Angeles. The Eleventh International Transport Theory Conference was funded by generous con tributions from Science Applications International Corporation, R. Beyster, president, and from Virginia Polytechnic Institute and State University. Conference participants, and, we believe, researchers in this and related areas, are indebted to these organizations. We would like to thank Lamberto Rondoni, in the graduate program at Virginia Tech, for proofreading manuscripts of all the Italian contributors.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 344 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -During the last two decades the theory of abstract Volterra equations has under gone rapid development. To a large extent this was due to the applications of this theory to problems in mathematical physics, such as viscoelasticity, heat conduc tion in materials with memory, electrodynamics with memory, and to the need of tools to tackle the problems arising in these fields. Many interesting phenomena not found with differential equations but observed in specific examples of Volterra type stimulated research and improved our understanding and knowledge. Al though this process is still going on, in particular concerning nonlinear problems, the linear theory has reached a state of maturity. In recent years several good books on Volterra equations have appeared. How ever, none of them accounts for linear problems in infinite dimensions, and there fore this part of the theory has been available only through the - meanwhile enor mous - original literature, so far. The present monograph intends to close this gap. Its aim is a coherent exposition of the state of the art in the linear theory. It brings together and unifies most of the relevant results available at present, and should ease the way through the original literature for anyone intending to work on abstract Volterra equations and its applications. And it exhibits many prob lems in the linear theory which have not been solved or even not been considered, so far.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 400 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -The Second International CBT (Center for Biotechnology) Synposium was held in Stockholm November 4-5 1988 and had the title 'The steroid/thyroid hoITIDne receptor family and gene regulation'. This meeting contained contributions from most leading laboratories within the field of steroid/thyroid hOITIDne receptors and gave a very exciting perspective on the dynamic development of this i:ntx>rt. ant research field. Today all known steroid hoITIDne receptors have been cloned and sequenced and novel members of this supergene family are constantly being discovered. Sane of these new receptors remain to be characterized regarding the nature of their ligand. Access to probes for steroid receptors has enabled studies on mechanisms of regulation of receptor gene expression. Deletion and II'Altational analysis of steroid receptor cDNAs followed by expression in cells together with suitable reporter genes has yielded a detailed knowledge about the functional significance of the various domains the receptors are composed of. In certain cases, steroid resistance in patients have been shown to be due to point mutations in the corresponding steroid receptor genes resulting in non-functional receptors. The availability of receptor cDNAs also makes it possible to express receptors at high levels in procaryotic and eucaryotic cells. It is e. g. possible to express the DNA-binding domain of the glucocorticoid receptor in E. coli as a fusion protein with protein A which interacts specifically with DNA. Such studies are necessary for production of sufficient quantities of receptors to allow crystallization and X-ray crystallography for detailed structural information.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 372 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -These proceedings contain a selection of papers presented at the Third European Conference on Multigrid Methods which was held in Bonn on October 1-4, 1990. Following conferences in 1981 and 1985, a platform for the presentation of new Multigrid results was provided for a third time. Multigrid methods no longer have problems being accepted by numerical analysts and users of numerical methods; on the contrary, they have been further developed in such a successful way that they have penetrated a variety of new fields of application. The high number of 154 participants from 18 countries and 76 presented papers show the need to continue the series of the European Multigrid Conferences. The papers of this volume give a survey on the current Multigrid situation; in particular, they correspond to those fields where new developments can be observed. For example, se veral papers study the appropriate treatment of time dependent problems. Improvements can also be noticed in the Multigrid approach for semiconductor equations. The field of parallel Multigrid variants, having been started at the second European Multigrid Conference, is now at the centre of interest.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 408 pp. Englisch.

It covers several selected topics on nonlinear wave-plasma interactio,ll in a treatment based on a hydrodynamic plasma description. Thus, no attempt has been made to give a comprehensive view on all aspects of the interaction of strong electromagnetic waves with plasmas. The text is partly introductory and presents partly current results. The authors hope that it will be of interest to students and scientists not only in the field of plasma physics.

Taschenbuch. Condición: Neu. Neuware -The biology of the family of endogenous autocrine peptides known as the endothelins (ETs) has been a source of intense study for researchers since 1988, following the identification of ET-l as the previously described endothelium-derived contractile factor. Initial interest focussed on the actions of the ETs in the cardiovascular system, and this remains the pri mary source of published work involving these peptides. Importantly, evi dence is mounting for a significant mediator role for ET-l in cardiovascu lar diseases including systemic hypertension and congestive heart failure. However, it was also recognized early on that the ETs exert an array of powerful actions in the respiratory tract, many of which prompted specula tion concerning mediator roles for ET-l in several lung diseases including asthma and pulmonary hypertension. In recent years the evidence for the involvement of ET-l in lung diseases has become more compelling. There is now real hope and anticipation that novel ET receptor antagonists may eventually be used therapeutically against asthma and other major lung pathologies. It is this atmosphere of excitement created by new discoveries and the increasing scientific ratio nale for a significant impact ofthe ETs in pulmonary diseases that prompt ed the creation of this book, the first on this topic. Most of the information presented relates to ET-l, which is the most widely studied member of the ET family.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 284 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Tamari lattices originated from weakenings or reinterpretations of the familar associativity law. This has been the subject of Dov Tamari's thesis at the Sorbonne in Paris in 1951 and the central theme of his subsequent mathematical work. Tamari lattices can be realized in terms of polytopes called associahedra, which in fact also appeared first in Tamari's thesis.By now these beautiful structures have made their appearance in many different areas of pure and applied mathematics, such as algebra, combinatorics, computer science, category theory, geometry, topology, and also in physics. Their interdisciplinary nature provides much fascination and value.On the occasion of Dov Tamari's centennial birthday, this book provides an introduction to topical research related to Tamari's work and ideas. Most of the articles collected in it are written in a way accessible to a wide audience of students and researchers in mathematics and mathematical physics and are accompanied by high quality illustrations.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 456 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -FirstEdition DUE TO THE necessity to save weight and materialin the design ofmodern structures and machines, stability problems have become increasingly im portant. The classicalengineering approach to this type of problem has been characterized by the tacit assumption that structures are nongyroscopic conservative systems,that is, bythegeneraladoptionofthemethodsdeveloped for this particular case. During the last decades numerous stability problems of a more complicated nature have become important, and it has therefore become necessary to correlate the various types of problems with the ap proaches to be used in their solution. The principal object ofthis little bookisthis correlation between the systems to be investigated and the methods to be used for this purpose, In other words, our main concern is the choice of a correct approach. It is evident that this idea renders it necessary to distinguish between the various types of problems or systems. At the same time the similarities and the connections between apparently quite different problems will become obvious, and it will be evident that there islittle differencebetween, say, the buckling of a column, thecritical speed of a turbine shaft, and the stability of an airplane, a control mechanism, or an electric circuit.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 160 pp. Englisch.

Dieses war die Plattform für eine kritische Evaluation der Erkenntnisse der Autoren, welche ihre Aussagen selbst zu verantworten haben. Eine kollektive Stellungnahme von Wissenschaftern aus völlig verschiedenen Gebieten in einem politisch und wissenschaftlich heiklen Umfeld hat ein besonderes Ziel, nämlich eine Besinnung auf einige grundSätzliche Erkenntnisse: - Substitution von Energieträgern, oder auch eine Substitution von Technologien ganz allgemein, braucht viel Zeit. Eine Substitution muss drei Phasen durchlaufen: Entwicklung, technische Reifung und Marktdurchdringung; jeder dieser Schritte dauert etwa 20 bis 30 Jahre. Der Zeitbedarf für die Einführung von neuen Technologien liegt gesamthaft somit in derselben Grössenordnung wie das befürchtete Eintreffen schwerer Auswirkungen des Treibhaus effektes. - Der Faktor Zeit ist neben den anderen Kriterien wie Sicherheit, Nachhaltigkeit und Akzeptanz unbedingt zu berücksichtigen, wenn neue Technologien bewertet werden sollen. Eine Technik, welche schon in der zweiten oder gar dritten Substitutionsphase steht, spart 20 bis 30 respek tive 40 bis 60 Jahre Zeit. - Eine Substitution auf dem Sektor Energie erfolgt nicht sequentiell, sondern verlangt über weite Strecken eine parallele Entwicklung der sich gegenseitig konkurrierenden oder ergänzenden Technologien. Diese sind den sektoriellen Bedürfnissen wie z.B. Haushalt, Industrie, Verkehr anzupassen.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 64 pp. Deutsch.

Neuware -When Richard Goldschmidt emigrated to the United States in 1936, he had influenced a whole generation of young biologists, and had stimulated their research by his revolutionary ideas. Stern (1967, see p. 21) called him: 'Contributor of permanent parts, some very large; preceptor and critic of his era; designer of frameworks for the future'. In 1958 Goldschmidt's obituary was prefaced by the following statement: 'Der nachstehende Nekrolog erscheint gleichzeitig in Science und Ex perientia, damit das universale Heimatrecht Richard Goldschmidts zum Ausdruck bringend. Die Leser von Experientia erinnern sich dankbar der verschiedenen genetischen Aufsiitze dieses immer anregenden Geistes, dem unsere Wissenschaft grosse Impulse verdankt.' (Translation: The following obituary appears simultaneously in Science and in Experientia, a symbol of Richard Goldschmidt's right to be called a world citizen. Readers of Experientia will recall with appreciation several of the papers of this highly stimulating author to whom our science owes a great deal. (Experientia 14, 307, 1958). In commemoration of the 20th anniversary of Richard Goldschmidt's death (April 24, 1958) and the 100th anniversary of his birth (April 12, 1878) Experientia presents a contemporary evaluation of several of Goldschmidt's major scientific theories. We believe that some of these theories were far ahead of his time and that the controversies which they aroused are of considerable didactic interest to biologists today. Further more, they represent an important chapter in the history of biology.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 156 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -This book brings together lmportant work on the structure and function of the dehydrogenases requiring nicotinamide coenzymes. The structure and function of lactate dehydrogen ase, alcohol dehydrogenase, and glyceraldehyde 3-phosphate dehydrogenase are compared. These are the relatively simple oligomeric dehydrogenases for which very extensive structural and mechanistic information is available. Kinetic studies are dealt with in general terms, with selected examples. Genetic and structural relationships revealed by primary structure are discussed. General features of the specificity of dehydrogen ase reactions are described. The pyridine nucleotide - disulphide oxidoreductases exemplify a type of multicomponent enzyme complex. Lipoamide dehydrogenase, glutathione reductase, and thioredoxin reduct ase are described and compared. The fatty acid synthesizing systems of some organ isms are nonaggregated, whereas in other organisms they are multienzyme complexes containing, in animal tissues for example, two closely related multifunctional polypeptide chains. The dehydrogenase activities of the fatty acid syn thesizing systems afford many points of interest, which are described and discussed. Hydroxymethylglutaryl-CoA reductase occupies a key position in the synthesis of isoprenoid compounds, including cholesterol. It probably occurs in all forms of life; in animal cells it is a microsomal enzyme. Its properties are reviewed.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 288 pp. Englisch.
