Buch. Condizione: Neu. Neuware - The first edition of Oncogenes (1989) focused on several of the better known transforming mechanisms and surveyed a spectrum of solid tumors and hematologic malignancies. Several of the nearly 50 known oncogenes most relevant to human disease were examined. In contrast, this volume presents a very different profile and balance of subject material that reflects the rapidly changing field of molecular oncology and its newly emerging concepts. Among the most important discoveries of the past 4 years are the identification of nearly a dozen different tumor suppressor genes and the finding of an entirely new class of cancer-causing gene (bcl-2) that acts by inhibiting cell death rather than stimulating cell proliferation. This edition begins by reviewing selected malignancies in which our earlier search for clinically relevant oncogenes has led to more focused studies on gain-of-function and loss-of-function genetic abnormalities, as well as autocrine and paracrine growth factor loops known to regulate tumor physiology and malignant cell behavior. Curiously, many of these genetic and functional abnormalities are shared by several different tumor types and are not uniformly present in all tumors of the same type. This observation brings up molecular questions about the tissue-specific determinants that underlie individual cancers and also gives added impetus to the suggestion that molecular abnormalities (referred to as tumor markers) be included among the histopathologic features used for clinical diagnosis and manage ment.

Buch. Condizione: Neu. Neuware - Origins of Plastids looks at symbiosis and symbiogenesis as a mechanism of evolution. This theory of endosymbiotic evolution postulates that photosynthetic prokaryotes living as endosymbionts within eukaryotic cells gradually evolved into the organelle structures called chloroplasts. The theory is controversial but has been strongly advocated by Lynn Margulis. Based on a colloquium held at the Bodega Bay Marine Laboratory of the University of California at Davis, Origins of Plastids reviews recent data on this most basic problem in plant evolution. In it, leading researchers in the field apply the theory of endosymbiotic evolution to plastid origins, producing an important new reference work for both professionals and graduates interested in the origins of life, the origins of the eukaryotic cell and its organelles, and the evolution of the higher plants in general. Origins of Plastids represents the state-of-the-art in its field. It should find a place on the bookshelves of people interested in microbiology, plant science, phycology, cell biology, and evolution.

Buch. Condizione: Neu. Neuware - Osteosarcoma in Adolescents and Young Adults: New Developments and Controversies is the fifth volume in the series `Cancer Treatment, and Research' devoted to pediatric oncology. Like its immediate predecessor, Hodgkin's Disease in Children: Controversies and Current Practice, this volume also deals with the current state of affairs: where do researchers differ in opinions or firmly held beliefs What does the future hold for research or for the patients who have benefited from research and are now cured etc. The first part deals with preclinical and clinical issues that relate to the disease and the second part deals with the results of recent trials and in some cases ongoing trials. It could be argued that section B Pharmacology, Section D Radiotherapy and Section E Surgery of part one belong to part two; however in these sections we have tried to focus on one discipline and in part two, we have tried to focus on the results of multidisciplinary trials. A third part includes a few critiques and editorial comments. This volume was prepared and planned for both basic and clinical oncologists. It is hoped that the basic scientists will gain some insight into the problems of their clinical colleagues and that the clinicians will be willing to read to the more basic articles. It is not a text for students (or for that matter physicians) who want all things to be laid out in `black and white'. But it is a text for those students who want to know how vibrant this field of research is and are willing to stand in awe of how much research needs to be done.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Design of Low-Voltage Bipolar Operational Amplifiers discusses the sub-circuits necessary to build a low-voltage operational amplifier. These include rail-to-rail input stages, rail-to-rail output stages, intermediate stages, protection circuitry and frequency compensation techniques. Of each of these, various implementations are examined. Furthermore, the book discusses realizations in silicon of the amplifiers. The design and implementation of low-voltage bipolar Operational Amplifiers (OpAmps) is fully presented. A low supply voltage is necessary because the tendency towards chip components of smaller dimensions lowers the breakdown voltage of these components. Further, a low supply voltage is favorable because it enables operation of the OpAmp from just one single battery cell. The bipolar technology is chosen, because it is more suited for operation at low-voltages than the MOS technology. The common-mode input voltage of the OpAmp must be able to have any value that fits within the supply voltage range. Input stages are discussed which are able to realize this at supply voltages down to 1.8 V, as well as down to 1 V. The output voltage of the OpAmp must be able to have any value within the supply voltage range. One of the 1 V output stages that is discussed, the multi-path driven output stage, also has a high bandwidth with a high gain. In addition to the input and output stage, the OpAmp comprises an intermediate stage, between the input stage and the output stage, to boost the overall gain of the OpAmp, and a class AB current control. A frequency compensation technique is used to split apart the pole frequencies in the transfer function. A disadvantage of this nested Miller compensation, is that the resulting bandwidth is reduced by a factor of two. A new method, multi-path-driven Miller compensation, which does not have this drawback, is therefore introduced. Several realizations are evaluated and a figure of merit is defined for the performance comparison of the OpAmps. One of the OpAmps operates at a 1 V supply, has a 3.4 MHz bandwidth with a 100 pF load and has a 700 &mgr;A supply current. The book is an excellent reference for professional designers of amplifiers and may be used as a text for advanced courses on the subject. 210 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -When we studied complex variables in the late 1960s, modem geometry on the complex fie1d and complex function theory were identified in teaching and research as several complex variables. A beginner in the field at that time would have the experience of jumping from the sheaf-theoretical methods employed in the theory of analytic spaces to the P.D.E. methods of the ä problem, with the c1ear understanding that the phenomena lying behind such different methods and problems were the same. A few years later, new important discoveries made c1ear that complex differential geometry was also in the same company. Looking at the historical development of the subject in the first half of the twentieth century shows this was not astonishing. The origin of the theory of functions of several complex variables was tardier than the familiar of analytic functions of one complex variable. The first comprehensive theory textbook by Behnke and Thullen, in the 1930s, expounded the foundations ofthe general theory as set up by Weierstrass, Cousin, Hartogs, and Poincare and c1early put in evidence that the difficulties were all but solved. In aseries of papers from 1936 to 1953, Oka introduced a brilliant collection of new ideas and systematically eliminated aU difficulties. Oka's work had in itse1f a fruitful seed and contained the premises for the opening of wider horizons. 436 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The main characteristics of the real-world decision-making problems facing humans today are multidimensional and have multiple objectives including eco nomic, environmental, social, and technical ones. Hence, it seems natural that the consideration of many objectives in the actual decision-making process re quires multiobjective approaches rather than single-objective. One ofthe major systems-analytic multiobjective approaches to decision-making under constraints is multiobjective optimization as a generalization of traditional single-objective optimization. Although multiobjective optimization problems differ from single objective optimization problems only in the plurality of objective functions, it is significant to realize that multiple objectives are often noncom mensurable and conflict with each other in multiobjective optimization problems. With this ob servation, in multiobjective optimization, the notion of Pareto optimality or effi ciency has been introduced instead of the optimality concept for single-objective optimization. However, decisions with Pareto optimality or efficiency are not uniquely determined; the final decision must be selected from among the set of Pareto optimal or efficient solutions. Therefore, the question is, how does one find the preferred point as a compromise or satisficing solution with rational pro cedure This is the starting point of multiobjective optimization. To be more specific, the aim is to determine how one derives a compromise or satisficing so lution of a decision maker (DM), which well represents the subjective judgments, from a Pareto optimal or an efficient solution set. 324 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -From the American Side I went to the USSR for the first time in 1982 to attend the 11th meeting of the International Union for Quaternary research (INQUA) held at the Moscow State University. At that time relations between our two countries were anything but congenial and many restrictions were placed on our viewing the archaeological and paleontological collections and labora tory facilities. This was not the ideal climate for the free exchange of ideas needed for meaningful research. However, it was obvious to us that the strained relations did not extend to scientific discussions between scholars. We left that meeting well aware that if the problems of prehistoric Old World-New World relationships were to be resolved, it would eventually require cooperative research efforts within the world community of archaeologists. At that time, the pre-Clovis problem in New World archaeology was foremost in the minds of many North American researchers: tool technology and assemblages were being studied as a possible means of establishing cultural relationships across the Bering Strait, Clovis sites and mammoth kills were being looked at with new ideas for interpretation, and New World researchers realized that to resolve these questions they had to become familiar with the archaeological record of northeast Asia. A chance meeting of the writer with Olga Soffer in 1983 led to serious discussions of the sites on the Russian or East European Plain. 358 pp. Englisch.

Neuware -This monograph is the proceedings of a symposium held at the University of California at Berkeley, September 12-14, 1990. It was sponsored by the Electric Power Research Institute (EPR!) and by the University of California University-Wide Energy Research Group (UERG). The sympo sium brought together researchers and practitioners from academia, the utility industry, private and public organizations and regulatory agencies to address various challenges and opportunities related to product differen tiation in the electric power industry. Electric utilities are evolving rapidly from commodity-oriented services to product-oriented services. Utilities are offering menus of service options tailored to the needs of different customers. Reliability is one important dimension of electric service that lends itself to such product differentia tion., Options include lower rate curtail able services for industrial cus tomers, higher reliability power for some commercial customers, and load control with rebates for residential customers., These specialized services are a first step toward the product differentiation goal of allowing all customers to choose the type of service best suited to their electricity needs. The symposium provided a forum for in depth examination of the complex planning, development, and implementation issues associated with differ entiated products. Its specific objectives were to: xviii ¿ Review the state of the art in implementing reliability differ entiated electric services. ¿ Address the entire process for developing and implementing reliability differentiated product menus including research, design, marketing, implementation, and evaluation. ¿ Consider technical, economic, and regulatory barriers to imple menting reliabilitydifferentiated product design.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 356 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Biomedical scientists widely acknowledge that individuals' immune respon siveness is important in resistance to infections by microorganisms, including fungi. Because of the devastating acquired immunodeficiency syndrome (AIDS) epidemic, caused by the human immunodeficiency retrovirus, it is now accepted that suppressed immune responses, especially cellular immu nity, are important contributors to increased individual susceptibility to opportunistic infections-including infections caused by fungi which were at one time thought to be very lowly or nonpathogenic. Within the last few years, there has been an almost explosive increase in interest and studies concerning the nature and mechanisms of the immune response to fungal infections. Many immunologists who are not well versed in mycology have begun to study the nature and mechanisms of antifungal immunity using a wide variety of newer as well as more conventional immunologic technologies, both in vivo and in vitro. Up to the 1980s, however, there was little interest among basic immunologists concerning fungal immunity. This situation has changed dramatically in the past half decade, mainly because of AIDS. 604 pp. Englisch.

Broutman and Associates (UBA) and as a lecturer in the seminars on this topic co-sponsored by UBA and Society of Plastics Engineers. I believe that by its extent and level of treatment, this book would serve as an easy-to-read desktop reference for professionals, as well as a text book at the junior or senior level in undergraduate programs. The main theme of this book is what to do with computed stress. To approach the theme effectively, I have taken the 'stress category ap proach' to stress analysis. Such an approach is being successfully used in the nuclear power field. In plastics, this approach helps in the prediction of long term behavior of structures. To maintain interest I have limited derivations and proofs to a minimum, and provided them, if at all, as flow charts. In this way, I believe that one can see better the connection between the variables, assumptions, and mathematics. 616 pp. Englisch.

About 60% of the text has been completely revised and major additions have been included which have produced a practically new text. My aim was to modernize the presentation but also to preserve the original results, some of which are little known to a Western reader. The idea of composites, which is the core of the modern theory of optimization, was initiated in the early seventies. The reader will find here its implementation in the problem of optimal conductivity distribution in an MHD-generatorchannel flow.Sincethen it has emergedinto an extensive theory which is undergoing a continuous development. The book does not pretend to be a textbook, neither does it offer a systematic presentation of the theory. Rather, it reflects a concept which I consider as fundamental in the modern approach to optimization of dis tributed systems. Bibliographical notes,though extensive, do not pretend to be exhaustive as well. My thanks are due to ProfessorJean-Louis Armand and ProfessorWolf Stadler whose friendly assistance in translating and polishing the text was so valuable. I am indebted to Mrs. Kathleen Durand and Mrs. Colleen Lewis for the hard job of typing large portions of the manuscript. 516 pp. Englisch.
