Taschenbuch. Condizione: Neu. Neuware - Interventional Oncology is a fast-growing new field, as well as an emerging specialty. Many minimally-invasive, imaging-guided procedures seem set to replace more traditional open surgical techniques of treating solid tumors in a variety of organs. The aim of this book is to describe new interventional radiological methods in a succinct and practical form. Diagnostic radiological considerations relevant to the selection and follow-up of patients are also covered. The book begins with an overview of the basic principles of current interventional techniques, including thermal ablation, high intensity focused ultrasound, and embolization. Later chapters focus on tumors of the liver, kidney, lung, and bone, placing new interventional techniques in context by referring to the surgical and oncologic methods of treating the same conditions. With an emphasis on best practices, Interventional Oncology: A Practical Guide for the Interventional Radiologist will serve as a definitive guide to practicing physicians involved in this rapidly evolving field.

Taschenbuch. Condizione: Neu. Neuware - Endocrinology, as a discipline, was a late arrival in the corpus of established subjects. Its growth in recent years has been prodigious, extending from mor phology to molecular levels. Most of the major endocrine glands were noted by the early anatomists, although the adrenal glands were not described until 1563 by Bartholomaeus Eustachius (1520-1574). On the other hand, elucidation of the function of these glands was extremely slow. Key work by A. A. Berthold (1849), although overlooked at the time, showed that comb atrophy in castrated fowl was prevented by testis transplantation. The idea that glands produced substances reach ing the bloodstream directly and not via excretory ducts stemmed from Claude Bernard, who first used the term internal secretion in 1855. The clinical observa tions of Thomas Addison at Guy's Hospital-published as a monograph in 1855 entitled The Constitutional and Local Effects of Disease of the Suprarenal Capsules -were seminal. However, the stimulus of this early research did not bring imme diate widespread further investigations. Upon the discovery of secretin in 1902, Bayliss and Starling considered the term 'internal secretion' to be clumsy, and the term 'hormone' was coined (from OQ[!UW-1 excite or arouse) and it was first used by Starling in his Croonian of 1905.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -To date nitrogen NMR has been discussed in research papers and review articles throughout the scientific literature. It has been our aim in preparing this book to provide a comprehen sive account of the widely spread applications of nitrogen NMR. The relevant literature has been surveyed from the beginnings of NMR until early 1972. The steady annual growth in the number of references cited since 1965 is ample evidence of the ever increasing importance of the subject. Sufficient theoretical and experimental background is given for an understanding of the applications dealt with in later chapters. The basic principles of NMR are developed with a theoretical approach to chemical shifts and spin-spin coupling constants, particular emphasis being given to nitrogen nuclei. Following this the experimental aspects of nitrogen NMR are adequately described. Special emphasis is given to the observable effects of the nuclear quadrupole moment of the 14 N nucleus. It is appro priate that this topic be dealt with in depth since quadrupolar interactions frequently dominate the information available from a study of the 14 N nucleus and other nuclei spin coupled to it. The applications of nitrogen chemical shift data to organic and inorganic molecules are covered in two extensive chapters which include the effects of paramagnetism on nitrogen NMR. 416 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Urolithiasis is a common disorder which is recognised in most parts of the world and occurs in both man and animals. The multifactorial nature of the problem requires an interdisciplinary approach which has always been a feature of this series of International Symposia which started in Leeds in 1968 and has progressed at four-yearly intervals through Madrid, Davos and Williamsburg. The latest Meeting, at Garmisch-Partenkirchen in April 1984, involved 302 participants from all five continents. The major emphasis of the Meeting was to blend the basic and clinical research on urolithiasis. Comprehensive reviews of the major areas of current research were presented by invited speakers, all internationally recognized experts in their fields. From more than 250 submitted abstracts, 18 were selected for oral presentation and the remainder presented at three afternoon poster sessions which provided an opportunity for informal and more lengthy discussions of the work on display. The Meeting also included three ad hoc Evening Discussions on how to approach various unsolved questions in the clinical and laboratory evaluation of stone patients and four Round Table Discussions involving specialists in the field who debated the theoretical aspects of stone formation in the urinary tract, the measurement of inhibitory activity of urine, the treatment of idiopathic stones with drugs, and the nature and treatment of stones arising from urinary tract infection. 1028 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The first edition of Integrated Methods for Optimization was published in January 2007. Because the book covers a rapidly developing field, the time is right for a second edition. The book provides a unified treatment of optimization methods. It brings ideas from mathematical programming (MP), constraint programming (CP), and global optimization (GO)into a single volume. There is no reason these must be learned as separate fields, as they normally are, and there are three reasons they should be studied together. (1) There is much in common among them intellectually, and to a large degree they can be understood as special cases of a single underlying solution technology. (2) A growing literature reports how they can be profitably integrated to formulate and solve a wide range of problems. (3) Several software packages now incorporate techniques from two or more of these fields.The book provides a unique resource for graduate students and practitioners who want a well-rounded background in optimization methods within a single course of study. Engineering students are a particularly large potential audience, because engineering optimization problems often benefit from a combined approach-particularly where design, scheduling, or logistics are involved. The text is also of value to those studying operations research, because their educational programs rarely cover CP, and to those studying computer science and artificial intelligence (AI), because their curricula typically omit MP and GO. The text is also useful for practitioners in any of these areas who want to learn about another, because it provides a more concise and accessible treatment than other texts.The book can cover so wide a range of material because it focuses on ideas that arerelevant to the methods used in general-purpose optimization and constraint solvers. The book focuses on ideas behind the methods that have proved useful in general-purpose optimization and constraint solvers, as well as integrated solvers of the present and foreseeable future. The second edition updates results in this area and includes several major new topics:Background material in linear, nonlinear, and dynamic programming.Network flow theory, due to its importance in filtering algorithms.A chapter on generalized duality theory that more explicitly develops a unifying primal-dual algorithmic structure for optimization methods.An extensive survey of search methods from both MP and AI, using the primal-dual framework as an organizing principle.Coverage of several additional global constraints used in CP solvers.The book continues to focus on exact as opposed to heuristic methods. It is possible to bring heuristic methods into the unifying scheme described in the book, and the new edition will retain the brief discussion of how this might be done. 660 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -VLSI for Wireless Communication, Second Edition, an advanced level text book, takes a system approach starting with an overview of the most up to date wireless systems and the transceiver architecture available today. Wireless standards are first introduced (updated to include the most recent 3G/4G standards in the second edition), and translates from a wireless standard to the implementation of a transceiver. This system approach is particularly important as the level of integration in VLSI increases and coupling between system and component design becomes more intimate. VLSI for Wireless Communication, Second Edition, illustrates designs with full design examples. Each chapter includes at least one complete design example that helps explain the architecture/circuits presented in this text. This book has close to 10 homework problems at the end of each chapter. A complete solutions manual is available on-line. VLSI for Wireless Communication, Second Edition, is designed as a primary text book for upper-undergraduate level students and graduate level students concentrating on electrical engineering and computer science. Professional engineers and researchers working in wireless communications, circuit design and development will find this book valuable as well. 572 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The present four volumes, published under the collective title of 'Chemical Bonds in Solids,' are the translation of the two Russian books 'Chemical Bonds in Crystals' and 'Chemical Bonds in Semiconductors.' These contain the papers presented at the Conference on Chemical Bonds held in Minsk between May 28 and June 3, 1967, together with a few other papers (denoted by an asterisk) which have been specially incorporated. Earlier collections (also published by the Nauka i Tekhnika Press of the Belorussian Academy of Sciences) were entitled 'Chemical Bonds in Semiconductors and Solids' (1965) and 'Chemical Bonds in Semiconductors and Thermody namics' (1966) and are available in English editions from Consultants Bureau, New York (pub lished in 1967 and 1968, respectively). The subject of chemical bonds in crystals, including semiconductors, has recently become highly topical and has attracted the interest of a wide circle of physicists, chemists, and engineers. Until recently, the most successful description of the properties of solids (including semi conductors) has been provided by the band theory, which still dominates the physics of solids. Nevertheless, it is clear that the most universal approach is that based on the general theory of chemical bonds in crystals, in which details of the electron distributions between atoms and of the wave functions appear quite expliCitly.' 148 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware - This book offers an analytical rather than measure-theoretical approach to the derivation of the partial differential equations of nonlinear filtering theory. The basis for this approach is the discrete numerical scheme used in Monte-Carlo simulations of stochastic differential equations and Wiener's associated path integral representation of the transition probability density. Furthermore, it presents analytical methods for constructing asymptotic approximations to their solution and for synthesizing asymptotically optimal filters. It also offers a new approach to the phase tracking problem, based on optimizing the mean time to loss of lock. The book is based on lecture notes from a one-semester special topics course on stochastic processes and their applications that the author taught many times to graduate students of mathematics, applied mathematics, physics, chemistry, computer science, electrical engineering, and other disciplines. The book contains exercises and worked-out examples aimed at illustrating the methods of mathematical modeling and performance analysis of phase trackers. 280 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Controlled thermonuclear fusion is one of the possible candidates for long term energy sources which will be indispensable for our highly technological society. However, the physics and technology of controlled fusion are extremely complex and still require a great deal of research and development before fusion can be a practical energy source. For producing energy via controlled fusion a deuterium-tritium gas has to be heated to temperatures of a few 100 Million °c corres ponding to about 10 keV. For net energy gain, this hot plasma has to be confined at a certain density for a certain time One pro mising scheme to confine such a plasma is the use of i~tense mag netic fields. However, the plasma diffuses out of the confining magnetic surfaces and impinges on the surrounding vessel walls which isolate the plasma from the surrounding air. Because of this plasma wall interaction, particles from the plasma are lost to the walls by implantation and are partially reemitted into the plasma. In addition, wall atoms are released and can enter the plasma. These wall atoms or impurities can deteriorate the plasma performance due to enhanced energy losses through radiation and an increase of the required magnetic pressure or a dilution of the fuel in the plasma. Finally, the impact of the plasma and energy on the wall can modify and deteriorate the thermal and mechanical pro perties of the vessel walls. 1216 pp. Englisch.
