Buch. Condizione: Neu. Neuware - This new work on oral complications of cancer chemotherapy is edited by two dentists who have made pioneering contributions in this previously neglected area. Their efforts have established the invaluable role of the dentist in oncologic research and cancer patient management. The editors have collected nine chapters that will be of interest to dentists and dental hygienists, oncology nurses, and all physicians treating cancer patients with chemo therapeutic agents. Background chapters on oral complications of cancer chemotherapy, the pharmacology of chemotherapeutic agents, and principles of infection management and prevention set the stage for more specific chapters focusing on prevention and treatment of chemotherapy induced oral and dental disorders. Valuable contributions to the supportive care of the cancer patient are contained in this book. A full comprehension of this book, coupled with an appreciation for advances in other areas of supportive care, such as antiemetic therapy and pain control, will allow all those involved in cancer treatment to be more successful.

Buch. Condizione: Neu. Neuware - The Fifth Ir Gene Workshop was held at the Chase-Park Plaza Hotel, St. Louis, MO, August 28-31, 1982; 240 scientists participated in the Workshop. The man uscripts compiled in this book describe the state of the art concerning Ir genes. Although the notion of Ir Genes: Past, Present, and Future has not been ad dressed specifically by each author, the reader is certain to get this flavor from the contributions. In this Preface, we have tried to summarize some of the salient ob servations and discussions from the Workshop. The mUltiple genes of the I region have been defined traditionally by serolog ical analysis of intra-H-2 recombinant mice and the pattern of immune responses to certain antigens developed by these recombinant mice. The application of sev eral new techniques, such as gene cloning and DNA sequencing, production of T and B cell hybridomas, and development of cloned T cell lines has changed this tradition and introduced a new phase into the analysis of the I region, Ia antigens, and Ir genes.…

Buch. Condizione: Neu. Neuware - Only in fairly recent years has History and Philosophy of Science been recognized - though not always under that name - as a distinct field of scholarly endeavour. Previously, in the Australasian region as elsewhere, those few individuals working within this broad area of inquiry found their base, both intellectually and socially, where they could. In fact, the institutionalization of History and Philosophy of Science began compara tively early in Australia. An initial lecturing appointment was made at the University of Melbourne immediately after the Second World War, in 1946, and other appointments followed as the subject underwent an expansion during the 1950s and '60s similar to that which took place in other parts of the world. Today there are major Departments at the University of Melbourne, the University of New South Wales and the University of Wollongong, and smaller groups active in many other parts of Australia, and in New Zealand. 'Australasian Studies in History and Philosophy of Science' aims to provide a distinctive publication outlet for Australian and New Zealand scholars working in the general area of history, philosophy and social studies of science. Each volume will comprise a group of essays on a connected theme, edited by an Australian or a New Zealander with special expertise in that particular area. The series should, however, prove of more than merely local interest. Papers will address general issues; parochial topics will be avoided.…

Buch. Condizione: Neu. Neuware - Lung cancer remains an extremely difficult neoplasm to treat effectively. A large part of our lack of success in dealing with these patients is related to our empiric therapeutic attempts. Slowly our basic understanding of the lung cancers is improving and techniques are becoming available to allow us to better understand the biology of these neoplasms. This volume reviews several areas of interest in regard to the biologic behavior and characteris of lung cancer. tics Chapters deal with the in vitro growth of small cell lung cancer, the inves tigation of growth factors in human lung cancer, the production of mono clonal antibodies against lung cancer and the application and potential use fulness of the human tumor cloning assay in lung cancer management. These avenues of investigation are likely to establish a more scientific basis on which more rational therapy can be designed. Carney and associates have established several continuous small cell lung cancer cell lines in their laboratory. The amine precursor uptake and decar boxylation (APUD) properties of this neoplasm have been confirmed by demonstrating the presence of neurosecretory granules and high levels of the APUD enzyme L-dopa decarboxylase. In addition, several new markers have been documented including bombesin, creatine-kinase BB and neuron specific enolase. These tumor products along with others may be useful serum markers in patients with small cell lung cancer.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The bond diagrammatic representation of molecules is the foundation of MOVB theory. To a certain extent, this kind of representation is analogous to the one on which 'resonance theory' is based and this fact can be projected by a comparison of the various ways in which MOVB theory depicts a species made up of three core and two ligand MO's which define two subsystems containing a total of six electrons and the ways in which 'resonance theory' (i. e. , qualitative VB theory) depicts a six-electron-six-AO species such as the pi system of CH =CH-CH=CH-CH=O. The 2 different pictorial representations are shown in Scheme 1 so that the analogies are made evident. First of all, the total MOVB diagrammatic representation of the 6/5 species is obtained by a linear combination of three complete bond diagrams, as in Al, which describe the optimal linear combination of!l! MOVB Configuration Wavefunctions (CW's). By the same token, a total VB diagrammatic representation of the 6/6 species can be obtained by writing a 'dot structure', as in Bl, and taking this to mean the optimal linear combination of all VB CW's. Next, we can approxi mate the MOVB wavefunction of the 6/5 species by one complete (or detailed) bond dia gram' (A2). No simple VB representation analogy can be given in this case. Alterna tively, we can approximate the MOVB wavefunction by a linear combination of compact bond diagrams, as in A3, in the way described before. 600 pp. Englisch.…

Neuware -The theory of Lie groups has proven to be a most powerful analytical tool in many areas of modern scientific endeavors. It was only a few years ago that economists discovered the usefulness of this approach in their study of the frontiers of modern economic theory. These frontiers include the areas of technical change and productivity, technology and preference, economic conservation laws, comparative statics and integrability conditions, index number problems, and the general theory of ~ observable market behavior (Sato [1980, 1981], Nono [1971], Sato and N~no [1983], Russell [1983]). 1 In Nono [1971] and Sa to [1981, Chapter 4] the concept of 'G-neutral' (group neutral) technical change was first introduced as a natural extension of the well-known concepts of Hicks, Harrod, Solow and Sato-Beckmann-Rose neutrality. The present monograph contains a further extension of the G-neutral technical change to the case of non-constant-returns-to-scale technology and to the case of multiple factor inputs. The methodology of total productivity estimation by means of Lie group transformations is also developed in this monograph. We would like to express our sincere thanks to many individuals notably to Professor M. J. Beckmann, Professor F. Mimura, Professor G. Suzawa, T. Mitchell, K. Mino and P. Calem, for their numerous contributions at various stages of this work. We are also grateful to Marion Wathey for her usual superb typing of this difficult manuscript. Providence, R. I. , U. S.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Our knowledge of postoperative thromboembolic complications has increased enormously over the past 2 decades, particularly where diag nosis and prophylaxis are concerned. The 125 I-fibrinogen method of diagnosing thrombosis has completely changed our concept of the frequency, occurrence, and natural course of thrombosis, and it has formed the basis of most thromboprophylactic studies. Concurrently with the development of this diagnostic method, two methods for the prophylaxis of thrombosis have come into vo gue, namely low-dose heparin and dextran. Both these methods were tested in very extensive studies during the seventies, and their value has been unequivocally proved, for reducing both the frequency of thrombosis with and without symptoms, and the frequency of fatal pulmonary embolism. Thromboprophylaxis is not particularly common in surgery; how ever, and its general use is far from uncontested. It has been argued that not only does it complicate surgical activities and make them mo re expensive, but it also involves an unacceptable number of other complications. 252 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -For some fields such as econometrics (Shore, 1980), oil prospecting (Claerbout, 1976), speech recognition (Levinson and Lieberman, 1981), satellite monitoring (Lavergnat et al., 1980), epilepsy diagnosis (Gersch and Tharp, 1977), and plasma physics (Bloomfield, 1976), there is a need to obtain an estimate of the spectral density (when it exists) in order to gain at least a crude understanding of the frequency content of time series data. An outstanding tutorial on the classical problem of spectral density estimation is given by Kay and Marple (1981). For an excellent collection of fundamental papers dealing with modern spec tral density estimation as well as an extensive bibliography on other fields of application, see Childers (1978). To devise a high-performance sample spectral density estimator, one must develop a rational basis for its construction, provide a feasible algorithm, and demonstrate its performance with respect to prescribed criteria. An algorithm is certainly feasible if it can be implemented on a computer, possesses computational efficiency (as measured by compu tational complexity analysis), and exhibits numerical stability. An estimator shows high performance if it is insensitive to violations of its underlying assumptions (i.e., robust), consistently shows excellent frequency resolutipn under realistic sample sizes and signal-to-noise power ratios, possesses a demonstrable numerical rate of convergence to the true population spectral density, and/or enjoys demonstrable asymp totic statistical properties such as consistency and efficiency. 236 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The essays in this volume were presented to Professor Isamu Yamada in honor of his seventy-third birthday. In view of his many professional contributions and associations, a single volume of essays is really insufficient to house the works of all those who wish to be part of a venture of this kind. Therefore, the editors would like to apologize to those friends and well-wishers of Professor Yamada who could not be accommodated in this volume. Born in Nagoya in 1909, Professor Yamada began his brilliant career at Nagoya Commercial College where he studied economics, statistics, mathematics and physics. After serving as a Professor of Economics and Statistics at Yokohama College between 1939-1940, Professor Yamada moved to Hitotsubashi University in Tokyo, where he served as a Professor of Econometrics until his retirement in 1973. Currently, he is teaching at Asia University as a Professor of Economics and Statistics. During his long tenure at Hitotsubashi University (where Professor Ichiro Nakayama, a 'Japanese Schumpeter', served as President of the University), Professor Yamada was instrumental in introducing several generation of students to the methods of modern econometrics. One of the editors (Ryuzo Sato) of this volume is a direct beneficiary of his lectures on modern econometric techniques. In the 1950's, Professor Yamada was one of several prominent Japanese economists who were selected for study abroad. It was during this time, on a visit to the Cowles Commission at the University of Chicago, that Professor Yamada met the other editor of this volume. 212 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -The material in this book reflects, in many respects, the culmination of several years of research regarding the measurement of monetary policy. On all the issues addressed in the text, I have thus attempted to provide a perspective of the type that can only be gained from 'living with' a topic over an extended time horizon. I have often said that I came to understand the monetary indicators literature only after having written dozens of papers on the subject. This statement may seem a bit trite, but I feel certain that anyone who has waded through this morass (or at least tried to) can fully empathize and recognize the grain of truth therein. It is my sincere hope that the synthesis given in the work will calm the fears and anxieties that often (and understandably) plague beginners in this field. In settling down to the process of 'pulling together' this manuscript, I was surprised to find the ease and consistency with which various topics, explored at widely diverse times and in no particular order, meshed into a unified whole. I attempted to write the book in a manner that would simultaneously be generally comprehensible to students (particularly at the graduate level) and to practitioners desiring a relatively thorough overview of the indicators literature and yet be of value to scholars desiring to explore (and hopefully advance) this field.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 164 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Applied Mathematics is the art of constructing mathematical models of observed phenomena so that both qualitative and quantitative results can be predicted by the use of analytical and numerical methods. Theoretical Mechanics is concerned with the study of those phenomena which can be ob served in everyday life in the physical world around us. It is often characterised by the macroscopic approach which allows the concept of an element or particle of material, small compared to the dimensions of the phenomena being modelled, yet large compared to the molecular size of the material. Then atomic and molecular phenomena appear only as quantities averaged over many molecules. It is therefore natural that the mathemati cal models derived are in terms of functions which are continuous and well behaved, and that the analytical and numerical methods required for their development are strongly dependent on the theory of partial and ordinary differential equations. Much pure research in Mathematics has been stimu lated by the need to develop models of real situations, and experimental observations have often led to important conjectures and theorems in Analysis. It is therefore important to present a careful account of both the physical or experimental observations and the mathematical analysis used. The authors believe that Fluid Mechanics offers a rich field for il lustrating the art of mathematical modelling, the power of mathematical analysis and the stimulus of applications to readily observed phenomena.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 160 pp. Englisch. …
