Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume is devoted to the chemistry, immunology, molecular biology, and physiology of the human chorionic gonadotropin, heG. For this glycoprotein molecule the course from discovery to chemical deciphering covered about fifty years. It was in 1928 that Ascheim and Zondek reported that urine from pregnant women contains something that stimulates the ovaries of mice or rats. This provided the basis for the famous A-Z test for pregnancy and for the 'rabbit test' modification introduced by Friedman. As researchers sought to find more sensitive responses to heG, they used a wide variety of species including the South African aquatic toad, Xenopus Zaevis, the terrestrial toad of South America, Bufo arinarus, and the African weaver finch, EupZeetes afra. The weaver finch feather reaction was particularly noteworthy, for it disclosed a non-gonadal response to heG/LH. In retrospect, this may have been an important evolutionary clue to the realization that the designation of the hormone as a 'gonadotropin' may have been only partially descriptive of the molecule's physiological function--a concept that is gaining attention, as the papers in this 1980 volume divulge. 520 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The contents of this book reflect a symposium held in honor of Professor Herman Kalckar's seventy-fifth birthday. His impact on the history of biochemistry is reflected by the diversity of the contributions of his former students and friends. Speakers came from Asia, Europe, and the United States to discuss both procaryotes and eukaryotes. The unifying theme was the cell membrane, both its organization and its function. Ektobiology, a topic that has held the attention of Professor Kalckar for many years, was clearly defined as a central topic in biology. This subject deals with the key structure whereby the cell interacts with the outside world and which, in a sense, defines the boundary between what is the cell and what is not. Topics discussed include the biogenesis of membrane proteins, sugars and lipids, the role of membrane components in osmoregula tion, and mechanisms of nutrient transport. Of great interest is the system for surface recognition evolved in vertebrates, exemplified by the HLA system of man. Neoplasia causes changes in the cell membrane that may be of significant future potential in the diagnosis and treatment of malignancies as well as in the understanding of the process of transformation. The changes in glycosphingolipids and carbohydrate antigens in relation to oncogenesis are detailed. I should like to recognize Doctors Kurt J. Isselbacher, Phillips W. Robbins, Victor Ginsburg, and Hiroshi Nikaido for their ,assistance in organizing the symposium. Ms. Jean Brumbaugh deserves special thanks for putting this book together. 312 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Noncrystalline (NC) solids, as is well known, lack the long range order of crystals. Accordingly, they exhibit scattering, e.g., x-ray, electron, and neutron, but not the diffraction patterns characteristic of crystals. The intensity distributions from NC solids are usually transformed into radial distribution functions (RDF), but the interpretation of the RDF's is not unique. The lack of long-range order, and the non-uniqueness of the structural interpretation, have constituted the main obstacles to the usual solid state physics approach which has been so successful in dealing with crystals. As a corrolary, questions of local order and structure have frequently been de-emphasized. This monograph contains a collection of chapters many of which emphasize local-structure and chemical bonding as opposed to long-range order. Most of the chapters were chosen from talks given at the international symposium, 'Structure and Bonding in Noncrystalline Solids,' held in Reston, Virginia in May of 1983. Other chapters, however, were simply submitted independently of the Reston conference. Thus, this book is not a proceedings of that conference, nor was it ever intended to be. The chapters presented here range from theory of bonding and structure, to structurally oriented measurements of various kinds, e.g., ESR, Raman, to more applied chapters. Our goal was to produce a monograph that enhances understanding of the structures of NC solids. 460 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Considering the enormous progress achieved in some special areas of superconductivity during the last few years, it seemed worthwhile to discuss thoroughly a subject, which has encountered severe pro blems on the theoretical and the experimental side, namely the effects of the anisotropic electron and phonon properties of (single crystalline) materials on the characteristic features of the super conducting state. The fact that the majority of scientists actively engaged in this research field at present were brought together at the meeting, has led to an almost complete coverage of the pertinent topics in this volume. Six review papers discuss the development and the present state of theory and experiment concerning the anisotropies of the upper critical field and the magnetization as well as the flux line lattice and the superconducting energy gap. Furthermore, 18 papers present the most recent research on these properties and additional anisotropy effects associated with the intermediate state patterns or the specific heat. Concerning the magnetic properties, remarkable agreement between theory and experiment has been achieved; on the other hand, controversial views regarding the existence of anisotropy in the superconducting energy gap are presented. In both cases, how ever, theorists and experimentalists are still confronted with a number of open questions. It is the purpose of this book to draw the attention of scientists to these fascinating problems. Harald W. 324 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The time seems ripe for a critical compendium of that segment of the biological universe we call viruses. Virology, as a science, having passed only recently through its descriptive phase of naming and num bering, has probably reached that stage at which relatively few new truly new-viruses will be discovered. Triggered by the intellectual probes and techniques of molecular biology, genetics, biochemical cytology, and high-resolution microscopy and spectroscopy, the field has experienced a genuine information explosion. Few serious attempts have been made to chronicle these events. This comprehensive series, which will comprise some 6000 pages in a total of about 22 volumes, represents a commitment by a large group of active investigators to analyze, digest, and expostulate on the great mass of data relating to viruses, much of which is now amorphous and disjointed, and scattered throughout a wide literature. In this way, we hope to place the entire field in perspective, and to develop an invaluable reference and sourcebook for researchers and students at all levels. This series is designed as a continuum that can be entered anywhere, but which also provides a logical progression of developing facts and integrated concepts. 516 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume contains the invited lectures presented in a symposium entitled 'Evolutionary strategies of parasitic insects and mites' at the national meeting of the Entomological Society of America in Minneapolis, Minnesota, 2-5 December, 1974. The intent was to bring together biologists who have worked on arthropods that are either plant or animal parasites in order to foster consideration of general aspects of the parasitic way of life. There seems to be a deficiency of ecological and evolutionary concepts relating to parasitism, in contrast to the burgeoning literature on predation, and it appeared that an amalgamation of studies on plant and animal parasites might help development of some generalities. Since parasities are far more numerous than predators in the world fauna, or in any particular community, emphasis on their study is justified. I freely admit that para sitoids have been usefully regarded as predators by ecologists, and many concepts on predation have been derived from their study. Also, in whichever category one places the parasitoids, that is the one which contains the most species. However, from an evolu tionary point of view they show many characteristics that must be regarded as those of a parasite. Notably, they are small, highly specific to their host, highly coevolved with it, as a result many species can coexist, and their adaptive radiation has produced the majority of the species diversity seen on Earth today. 240 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The International Workshop on 'The Use of Super computers in Theoretical Science' took place from July 30 till August 1, 1984, at the Conference Center of the 'Priorij Corsendonk', close to the city of Antwerpen, Belgium. During the past decade computational science has developed itself to a third methodology besides the experimental and theoretical sciences. This remarkable evolution was only possible due to a drastic increase of the computational power of present day computers. Indeed, computational physics and chemistry as such is certainly not new, but it was only during the past ten years or so that realistic problems could be solved numerically to a sufficient degree of accuracy. During this workshop the state-of-the-art in high speed computation was presented by a team of lecturers who are well known for their competence in this field. It is a pleasure to thank several organizations and companies who made this workshop possible. First of all, the main sponsors: the Belgian National Science Found ation (NFWO-FNRS) and the 'Universitaire Instelling Ant werpen'. Next, the co-sponsors: Agfa-Gevaert N. V., Control Data Belgium and the Belgian Ministry of Education. Special thanks are due to Dr. P.E. Van Camp and Drs. H. Nachtegaele for the practical organization of this workshop. I would also like to thank Mrs. H. Evans for typing the manuscripts and for preparing the author and subject index. v Last but not least I express my gratitude to Mr. 240 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The literature of medicine continues to expand at a remarkable pace. The number of papers and monographs published has increased dramatically in the past five years. Nowhere has this increase been as dramatic as in the field of acute and chronic hepatitis. Why then should there be still another book Despite the sheer volume of words published, it is still difficult to find in anyone volume a compilation of all of the most significant work. Most mono graphs have considered either chronic or acute hepatitis, not both. Few works have addressed both the clinician and the basic scientist. This book addresses both of these audiences and considers both of these diseases. It was designed to provide an authoritative but concise assessment of our changing concepts of acute and chronic hepatitis. It covers what is currently known and, based on the most convincing research, believed about these diseases. To fulfill this ambitious goal, only authors with international reputations in their fields of expertise were invited to contribute. In the evolution of our current thoughts on the pathogenesis and manage ment of acute and chronic hepatitis, our ideas have changed several times. This book presents the facts as they are known today and, in areas where all the facts are not established, presents the well-founded opinions of those considered to be authorities. The authors present established and usually confirmed data and do not deal extensively with areas of speculation or unconfirmed material. 360 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Symposium on Asymptotic Structure of Space-Time (SOASST) was held at the University of Cincinnati, June 14-18, 1976. We had been thinking of organizing a symposium on the properties of 'in finity' for several years. The subject had reached a stage of maturity and had also formed a basis for important current investi gations. It was felt that a symposium, together with a publication of the proceedings, would review, summarize, and consolidate, the more mature aspects of the field and serve as an appropriate intro duction to an expanding body of research. We had from the first the enthusiastic support and encouragement of many colleagues; with their cooperation and advice, the Symposium acquired its final form. These proceedings will attest to the value of the Symposium. The Symposium consisted of thirty lectures and had an attendance of approximately one hundred and thirty. The final impetus to our decision to go forward was the Bicen tennial Anniversary of the independence of our country. A most appropriate celebration on a University Campus surely is an intel lectual Symposium which pays honor to the histories and traditional purposes of a University. The Symposium was supported financially by the University of Cincinnatl Bicentennial Committee, the National Science Foundation, the Gravity Research Foundation, and by Armand Knoblaugh, Professor Emeritus of Physics of the University of Cincinnati. 456 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Conference on the Benthic Boundary Layer was held under the auspices of the NATO Science Committee as part of its continuing effort to promote the useful progress of science through international cooperation. Science Committee Conferences are deliberately designed to focus attention on unsolved problems, with carefully selected participants invited to provide complementary expertise from a variety of relevant disciplines. Through inten sive discussion in small groups they seek to reach a consensus on assessments and recommendations for future research emphasis, which it is hoped will be of value to the larger scientific community. The subjects treated over the past few years have been as varied as science itself-e.g., computer software engineering, chemical catalysis, and materials and energy research. The present effort evolved from informal discussions between marine geolo gists, chemists, and biologists which underlined the desirability of improved communication among those concerned with the benthic layer. In both scien tific and technological terms this is an exciting frontier, rich in promise but poorly understood at present. It is particularly striking to realize that there are at least as many definitions of the benthic layer as there are disciplines involved, and it seemed clear that there was much to be gained by a detailed exchange of views on research capabilities, trends, and priorities. The results of the meeting appear to have confirmed the hopes of the sponsors. 336 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Sherrington School of Physiology at St. Thomas' Hospital provided a natural venue for four days of enthusiastic debate on Sherrington's Final Common Path -the alpha motoneurone and related matters; Sherrington himself held a lecturership at St. Thomas' just over a century ago. The occasion was a happy one. Most participants already knew each other, the topics were familiar, the discussion was vigorous and critical but without personal rancor. The program had set out to encourage debate with 'critiques' both of the oral papers and the posters; their inclusion in the present volume helps to show where we are standing on rock rather than sand. In spite of a venerable history some surprisingly simple matters remain controversial, such as the information content of the signals from the Golgi tendon organs. To those working on alpha and gamma motoneurones and their control this volume provides an essential up-dating. Classical problems continue to be attacked on a broad front; advance is steady and continuous, a swelling tide rather than a sudden view of the summit. But in some sectors the difficulties are so great that to the outsider little might seem to change, the same battles continuing; but even here, the terms of debate change and concensus develops. Other branches of biology claim breakthrough upon breakthrough from the routine application of the new technologies, so we have to be the first to ask whether our classical approach to science can still be justified. 656 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This book contains the lectures delivered at the NATO Advanced Study Institute on 'Physics and Applications of Quantum Wells and Superlattices', held in Erice, Italy, on April 21-May 1, 1987. This course was the fourth one of the International School of Solid-State Device Research, which is under the auspices of the Ettore Majorana Center for Scientific Culture. In the last ten years, we have seen an enormous increase in re search in the field of Semiconductor Heterostructures, as evidenced by the large percentage of papers presented in recent international conferences on semiconductor physics. Undoubtfully, this expansion has been made possible by dramatic advances in materials preparation, mostly by molecular beam epitaxy and organometallic chemical vapor deposition. The emphasis on epitaxial growth that was prevalent at the beginning of the decade (thus, the second course of the School, held in 1983, was devoted to Molecular Beam Epitaxy and Heterostructures) has given way to a strong interest in new physical phenomena and new material structures, and to practical applications that are already emerging from them. 468 pp. Englisch.

During this same period another development took place in psychiatry, namely, social and community psychiatry, interpreted by some, incorrectly, in my opinion, as the antitheses of the biological approach. The whole area of the delivery of mental health services, which quickly became more of a political and social issue than a medical one, led to confusion, disillusionment, despair, and also soul-searching by psychiatrists and other mental health professionals. The remarkable Pablo Picasso said, 'the development of photography freed the artist to express his own creativity. ' I have paraphrased Picasso's insightful remark, namely, 'the development of biology and social and community psychiatry should free the psychiatrist to express his own creati vity as a physician. ' It should allow him to regain his basic medi cal identity. As his medical identity becomes paramount, then the pejorative classification of psychiatrists into those 'organically oriented' and those 'dynamically-oriented' will no longer be valid. The psychiatrist, like his medical colleague, must be concerned with the psychological, psychosocial, biological, and technical aspects of psychiatry. The strengthening and development of the medical identity of the psychiatrist imposes increased responsibilities on him and on psychiatry as a medical discipline. On the one hand, he will have to become more of a neuro-bi_ gist and, on the other, more of a behavioral scientist. 292 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is unclear, and really no longer relevant, whether the information explosion that we now contend with has been fostered by the growth of specialization and subspecialization in medicine, or vice versa. What is clear is that the two are mutually supportive and constitute what would be in endocrine parlance a short-loop positive feedback system. As a result, for most areas of medicine, even the subspecialist in that area has a problem in maintaining currency, the more general specialist has substan tial difficulty in doing so, and the generalist is tempted to abandon the effort altogether. Nevertheless, for all, both the internal pressures of conscience and self-esteem and the external pressures generated by peer review, recertifi cation, and subspecialty boards create the need for continuous self-educa tion. We are, therefore, in an era in which the means of dissemination of new information deserves as much creative attention as does its acquisition. 348 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is most appropriate that the first volume to appear in the series 'Advanced Applications in Pattern Recognition' should be this monograph by Nagao and Matsuyama. The work described here is a deep unification and synthesis of the two fundamental approaches to pat tern recognition: numerical (also known as 'statistical') and struc tural ('linguistic,' 'syntactic'). The power and unity of the meth odology flow from the apparently effortless and natural use of the knowledge-base framework illuminated by the best results of artificial intelligence research. An integral part of the work is the algorithmic solution of many hitherto incompletely or clumsily treated problems. It was on the occasion of a laboratory visit in connection with the 4th IJCPR (of ~hich Professor Nagao was the very able Program Chairman) that I saw in operation the system described here. On the spot I expressed the desire to see the work described for the inter national technical audience in this series and the authors were kind enough to agree to contribute to a new and unknown series. With the publication of this monograph on the eve of the 5th ICPR my wish is fu1fi11~d. I want to thank here the authors and Plenum Publishing Corporation for making this volume and the series a reality. 236 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -On May 14-16, 1982, a group of scientists met in Viareggio, Italy to present ideas, and exchange relevant data on current approaches on immunomodulators. We felt that the embodiment of the substance of that international symposium into this volume will be beneficial in keeping both clinicians and basic scientists abreast of the latest exciting developments in this rapidly accelerating field. We hope that the publication of this series of papers by an international panel of experts will enhance the nature of future inves t igat ive stud ies with such ent it ies . Under the rubric of immunology, it is obvious that such a term as 'immunomodulation' could be construed as being all encompassing. However, it is intriguing that the immune modulators touched on in these sessions can be subcategorized into about five broad groups. Almost all substances, excepting those entities that are immuno logically inert, will have some modulating effects on immunity. From the coarse adjustment of antibody feedback inhibition upon cellular limnunity to the subtle finesse envisioned in Jerne's idiotypic network and s'lppressor T cells, immunomodulators attempt to either magnify or diminish those responses that are normally elicited by antigen. The broad groups - thymic hormones, D.L.E., Interferon, drugs, and the use of bacterial products appear to be at the forefront of much of the pioneering work on immunomodulation. 472 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -For my past sins, Leslie Ettre has given me the privilege of writing a few words to preface his excellent little book. It gives me great pleasure to do so, because of the many years of fruitful collabo ration we have had at Perkin-Elmer, because it is refreshing to see a treatise in gas chromatography in which the theoretical treatment has been bared to its essentials, without a mushrooming of formulae which, by means of an ever increasing number of parameters, account for more and more, and explain less and less, and because the author has recognized that the gas chromatographic column is a nearly passive element in its own right which deserves to have a treatise written nearly exclusively about it, just as electrical circuit theory can be discussed without elaborate references to vacuum tubes and meters. I wish this conscientiously written volume the success it deserves. M. J. E. GOLAY VII Preface Gas chromatography is a separation technique used primarily in analytical chemistry. Therefore, it is evident that special emphasis should be placed on that particular part of the apparatus in which the separation takes place. This part is the column, the heart of the gas chromatograph. The goal of researchers in the field of gas chromatography has been-from the beginning-to understand the separation process so that they might design columns with the best possible performance. Such investigation led M. J. E. 188 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -According to the classical concept of Geoffrey Harris the pituitary gland is controlled by the brain by means of blood-borne chemical messengers produced by central neurons. The recent isolation and structural characterization of several such messengers by Roger Guillemin and Andrew Schally and their collaborators brought the final proof for this hypothesis. This also meant that the extensive knowledge collected in the field of neurobiology now became highly relevant for the endocrinologists. For this reason it was felt important to organize a symposium which brought together experts in the fields of neurobiology and endocrinology. The idea was to focus the attention on neuronal mechanisms, particularly those related to chemical transmission, which may be of importance for the central regulation of hormonal secretion patterns. We would like to express our sincere gratitude to the Nobel Founda tion for supporting the organization of the Nobel Symposium 42 on 'Principles of the Central Regulation of the Endocrine System'. We would also like to express our thanks to all participants, to Professor Carl-Gustaf Bernhard, Permanent Secretary of the Royal Academy of Sciences, for making the facilities of the Academ- available to us, and to the Symposium secretaries Mrs. Gun Hultgren, Mrs. Lena Persson and Mrs. Ulla-Britt Wedin.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume derives from papers presented at the 4th biennial meeting of the Italian Biophysical Society, held in Parma in October 1979. It includes review lectures presented by guest scientists (R.H. Adrian, E. Neher, S. Ottolenghi, and G. Zaccai); the remaining reviews and papers present some of the problems currently under study in our country. One can see that biophysical problems are studied under differ ent academic roofs, i.e., at physiological or biochemical departments. We consider this a strength and a weakness at the same time. The 'Italian Bioenergetics Group' contributed to the success of the meeting, as much as the groups working in various laboratories of the Consiglio Nazionale delle Ricerche, in particular those of the National Group of Cybernetics and Biophysics. To them, and to the University of Parma, which contributed financial and organiza tional support, the Editors of this volume wish to express their appreciation. Particular thanks are to Drs. E. Carbone and V. Lenci, who spent time and effort for the meeting and in collecting the papers. The special care in the typing goes to the credit of Miss Rampello, to whom the Editors express their deepest gratitude. 380 pp. Englisch.

In the past 15 years, this national network has collected a large body of data on all of the recognized anti-tumor drugs as well as upon new, experimentally promising agents. While the most important of these studies have been published, there has remained a wealth of data not generally available to the scientific community. Drs. Carter and Livingston have not only succeeded in organ~z~ng this large corpus, they have in addition analyzed and interpreted the clinical data in a way that will be highly useful for years to come. From a perusal of this volume it becomes apparent that some drugs are more active against certain tumors than had been realized; that the evidence for the activity of certain drugs against specific tumors is sometimes tenuous; surprisingly, that some highly active agents have never been tried against some of the fairly common tumors. Their monumental work has provided not only access to the hard data, it has also shown the need for research to fill in important gaps in our knowledge. The authors and the IFI/Plenum Press are to be congratulated for this useful and important work. C. Gordon Zubrod, M. D.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The purpose of this book is to interpret more sensitively some of the offerings of the standard text book of general chemistry. As a supplement thereto, it covers various aspects of formulation and stoichiometry that are frequently treated far too perfunctorily or, in many instances, are not considered at all. The inadequate attention often accorded by the comprehensive text to many topics within its proper purview arises, understandably enough, from the numerous broad and highly varied objectives set for the first year of the curriculum for modern chemistry in colleges and universities. For the serious student this means, more often than not, the frustrations of questions unanswered. The amplification that this book proffers in the immediate area of its subject covers the equations representing internal redox reactions, not only of the simple but, also, of the multiple disproportionations of which the complexities often discourage an undertaking despite the challenge they offer: distinctions to be observed in the balancing of equations in con trasting alkali-basic and ammonia-basic reaction media; quantitative contributions made by the ionization or dissociation effects of electrolytes to the colligative properties of their solutions; intensive application of the universal reaction principle of chemical equivalence to the stoichiometry of oxidation and reduction. 236 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume contains the proceedings of a workshop which was held in Brussels during the month of August 1989. A strong motivation for organizing this workshop was to bring together people who have been involved in the microscopic simulation of phenomena occuring on 'large' space and time scales. Indeed, results obtained in the last years by different groups tend to support the idea that macroscopic behavior already appears in systems small enough so as to be modelled by a collection of interacting particles on a (super) computer. Such an approach is certainly desirable to study situations where no satisfactory phenomenological theory is known to hold, or where solutions of the equations are too hard to obtain numerically. It is also interesting from a more fundamental point of view, namely the investigation of the limits of validity of the macroscopic description itself. The main technique used in bridging the gap between the macro and micro worlds has been the molecular dynamics simulations, that is the numerical solution of the equations of motion of the model particles which constitute the system under study, a gas, a liquid or even a solid. However, this technique is by no means the only one. 388 pp. Englisch.

The genesis of this Conference came from the work of the Subcommittee on Nutrition and Fertility of the Committee on International Nutrition Programs of the National Research Council. The purpose of the Conference was to assemble scientists and program planners from a broad range of fields including nutrition, epidemiology, demography, endocrinology, sociology, economics, anthropology, biostatistics and public health. Each individual brought his or her analytical skills and perspective to the meeting, with the goal of developing a more coherent picture of the many facets of nutrition and reproduction. The approach was to get a more comprehensive view by: 1. Clarifying terminology and definitions. 2. Reviewing recent and current work on the biological basis for nutrition-fertility interactions. 3. Reviewing biomedical and socioeconomic factors related to breast-feeding to assess how this practice relates to maternal and infant nutrition and fertility. 4. Assessing some current analytical models for defining nutrition-fertility interrelationships. 5. Reviewing recent field studies from Africa, Asia and Latin America which are examining the interrelationships of nutrition and reproduction. 528 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This book contains the papers and discussions from the sympo!,ium on 'The Catalytic Chemistry of Nitrogen Oxides' held at the General Motors Research Laboratories on October 7-8, 1974. This symposium is the eighteenth in the annual series presented by the Research Laboratories. The topics for these symposiums have covered a broad range. Each topic was selected to be of intense current interest and of significant technical importance. There is no question that the subject of the 1974 Symposium satisfies these two criteria. The control of automotive nitrogen oxides has been perhaps the most difficult and controversial area of automotive emissions both in terms of what is necessary and in terms of what is technically feasible. This area has been a source of considerable discussion not only in the technical community but also in governments both in the U. S. and abroad. This meeting brought together scientists working in surface chemistry with engineers working on system design. It also brought together representatives of government, academia and industry. We feel that an important side benefit of the meeting was the improved understanding that was developed between these groups. Participants came from Europe and Japan as well as Canada and the United States. The technical papers spanned the range from fundamental interactions of NO on surfaces through bench scale kinetic and mechanistic studies and ended with catalytic applications. Although the emphasis was on automotive NO removal, stack gas NO x x control was also covered. 352 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This book contains papers on sparse matrices and their appli cations which were presented at a Symposium held at the IBM Thomas J. Watson Research Center, Yorktown Heights, New York on September 9-10, 1971. This is a very active field of research since efficient techniques for handling sparse matrix calculations are an important aspect of problem solving. In large scale problems, the feasibility of the calculation depends critically on the efficiency of the underlying sparse matrix algorithms. An important feature of the conference and its proceedings is the cross-fertilization achieved among a broad spectrum of application areas, and among combinatorialists, numerical analysts, and computer scientists. The mathematical, programming, and data management features of these techniques provide a unifying theme which can benefit readers in many fields. The introduction summarizes the major ideas in each paper. These ideas are interspersed with a brief survey of sparse matrix technology. An extensive unified bibliography is provided for the reader interested in more systematic information. The editors wish to thank Robert K. Brayton for his many helpful suggestions as chairman of the organizing committee and Redmond O'Brien for his editorial and audio-visual assistance. We would also like to thank Mrs. Tiyo Asai and Mrs. Joyce Otis for their help during the conference and on the numerous typing jobs for the manuscript. A special thanks goes to William J. Turner for establishing the IBM Research Symposia Series with Plenum Press. 232 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -My favourite literary critique comes from the little girl in James Thurber's The Darlings at the Top oj the Stairs: 'This book tells me more about penguins than I wanted to know'. My daughter Clio, who learned the alphabet by typing words for the first draft of this book, has similar sentiments about the present work, and she suggests that my next effort 'should be quite short, maybe four pages'. However, this is an epistemological work, in a very general sense. It deals not only with the 'facts' of evolutionary biology and its interpretive logic, but also considers intellectual progress and prejudice, soul-searching and gullibility, and heuristic induction and wishful thinking; which may be more about penguins than students accustomed to cut-and-dried assertions, and teachers who cut and dry, might want to know. Some of my penguins, progenitors of significant epistemological lines, have been detailed down to the last feather, including a number of birds that by conventional wisdom, 'nobody takes seriously'. Some are sketches copied from other naturalists; others are phantoms that cry out for an incarnation denieci by a combination of accident and time constraints. Students in my courses in comparative physiology and the history and philosophy of biology have been the main sounding boards for my ideas. Richard Ring has always listened with polite interest when I have expatiated. 416 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Differential psychology, or the psychology of individual differences as it is better known, is perhaps the single most important basic psychological science that underlies professional practice in psychology. The recent age of behaviorism all but ignored individual differences, but in this decade the study has emerged from relative dormancy with a new vitality, fueled by new concepts, technologies, statistics, and new viewpoints on old ideas that are moving us forward. This work is intended to be a review of as well as a primer on many of these advances and new approaches to the study of individual differences. The venerable, interesting, and often controversial Eysenck opens the volume with a review of recent results and new techniques for unlocking the physiological basis of what is commonly understood to be intelligence. Eysenck and his students, in his London laboratory, have been fostering advances in this field for more than four decades. Their latest work could be the most exciting of Eysenck's illustrious, scholarly career. Eysenck's eye-opening, innovative work on the relationship between evoked potentials and performance on traditional psychometric measures, presented with a new slant, is certain to attract much attention in coming years. Eysenck and Barrett's chapter is followed by a closely related work by Arthur Jensen, who gives us a revitalizing look at the concepts of Sir Francis Galton, the founder of the psychology of individual differences. 496 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The finite element method (FEM) has been understood, at least in principle, for more than 50 years. The integral formulation on which it is based has been known for a longer time (thanks to the work of Galerkin, Ritz, Courant and Hilbert,1,4 to mention the most important). However, the method could not be applied in a practical way since it involved the solution of a large number of linear or non-linear algebraic equations. Today it is quite common, with the aid of computers, to solve non-linear algebraic problems of several thousand equations. The necessary numerical methods and programming techniques are now an integral part of the teaching curriculum in most engineering schools. Mechanical engineers, confronted with very complicated structural problems, were the first to take advantage of advanced computational methods and high level languages (FORTRAN) to transform the mechanical models into algebraic equations (1956). In recent times (1960), the FEM has been studied by applied mathematicians and, having received rigorous treatment, has become a part of the more general study of partial differential equations, gradually replacing the finite difference method which had been considered the universal tool to solve these types of problems. 208 pp. Englisch.

And this is particularly true in the matter of writing proposals, which are the crucial element in most major procurement awards. It's true enough, as many suspect, that the big, well-known company has something of an edge over the smaller, lesser-known company com peting for any given government contract-psychologically, at least: The typical government executives, whether contracting officials or program managers, tend to have a bit more faith in the ability of the large company to carry out the program successfully. All things being equal, then, the big company is more likely to get the nod. However, because the large companies are well aware of that, many tend to become 'fat, dumb, and happy'-they try to coast or rest on their laurels. That is, they get careless about making a strong enough case for themselves in writing their proposals. And when they lose, often to smaller companies, they are both puzzled and outraged. They have for gotten that all government procurement is a competition-usually both technical and cost competition-and that the 'little guy' can win against the 'big guy,' if he tries hard enough. And especially if the bigger guy is a bit careless and does not put out his best effort. 308 pp. Englisch.
