Taschenbuch. Condizione: Neu. Neuware -The discovery of new molecules that function in neuronal communication can be viewed as a progression of steps beginning with the identification of the molecular structure, moving to the understanding of the mecha nisms mediating the synaptic action, and to the appraisal of the involve ment of the new molecules in various neuronal mechanisms, and finally reaching the evaluation of this molecule's role in brain function and the consequences that are triggered by its abnormalities. Enkephalins have followed such a pattern, and the present publication expresses the salient points of the last two phases in this succession. Enkephalins were discovered in December 1975; in addition to pain threshold regulation, their participation in other brain functions was soon ascertained. Perhaps, there are multiple recognition sites for multiple molecular forms of endogenous enkephalins; similarly to other transmitter recognition sites, these are coupled with ionic and nucleotide amplifying systems; thus, when activated, they can modify membrane funtion and ionic permeability of membranes. The present publication probes the current status of our knowledge concerning the consequences related to abnormalities in enkephalin storage, release, and synthesis. However, since our basic understanding of enkephalins is incomplete, the views reported should be considered to be in a state of flux.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 512 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This book deals with the underlying theory and practical aspects of pressure gauges that are at present in general use. Because of the ever-increasing demands to provide a wider range of sophisticated and reliable vacuum equipment a good understanding of these instruments is of vital importance to all workers in the research and industrial sectors. Of the gauges considered only the mechanical types are absolute, in the sense that they measure pressure directly as a force upon a liquid column or a solid surface. Under ideal conditions it is possible to calculate their sensitiv ities, which are the same for all gases and vapours. The recent developments in the viscous or molecular damping gauges indicate that these may also be considered absolute. Other gauges are indirect in that they involve the measurement of some secondary phenomenon which is pressure-dependent and therefore these gauges can only be used for measurement after calibration against an absolute standard. The radiometer or Knudsen type gauge has been excluded from the text since these are now only of historic interest. Also no mention is made of the integration techniques involving surface changes (such as work function) although these could have application under very special circumstances. The McLeod gauge is dealt with in some detail, for even though this gauge has few practical applications, it is the most sensitive absolute gauge available and has value as a reference standard.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 212 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The use of computer-aided design (CAD) systems always involves the introduction of mathematical concepts. It is important, therefore, for any systems designer to have a good grasp of the mathematical bases used in CAD. The choice of mathematical models in a system also has an effect on the overall quality, although this effect may not always be visible to the final user. Depending on whether Bezier or B-spline functions are used for curves and surfaces, for example, the final user even if not a com puter scientist will notice a difference. If, for example, one of the control points is modified by the user, in a Bezier-type representation, the curve or surface will tend to be modified overall, but in a B-spline representation, the curve or surface will tend to be modified close to the point, and there only. More possibly harmful, however, is the effect of the mathematical model which has a number of properties invisible and unknown to the final user. In every case a model must be chosen with, it is hoped, the most appropriate characteristics and limits for the task in hand.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 168 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Advances in Non-Linear Modeling for Speech Processing includes advanced topics in non-linear estimation and modeling techniques along with their applications to speaker recognition.Non-linear aeroacoustic modeling approach is used to estimate the important fine-structure speech events, which are not revealed by the short time Fourier transform (STFT). This aeroacostic modeling approach provides the impetus for the high resolution Teager energy operator (TEO). This operator is characterized by a time resolution that can track rapid signal energy changes within a glottal cycle.The cepstral features like linear prediction cepstral coefficients (LPCC) and mel frequency cepstral coefficients (MFCC) are computed from the magnitude spectrum of the speech frame and the phase spectra is neglected. To overcome the problem of neglecting the phase spectra, the speech production system can be represented as an amplitude modulation-frequency modulation (AM-FM) model. To demodulate the speech signal, to estimation the amplitude envelope and instantaneous frequency components, the energy separation algorithm (ESA) and the Hilbert transform demodulation (HTD) algorithm are discussed.Different features derived using above non-linear modeling techniques are used to develop a speaker identification system. Finally, it is shown that, the fusion of speech production and speech perception mechanisms can lead to a robust feature set.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 116 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -High pressure science is a rapidly growing diverse fi. e1d. The high pressure technique has become a powerful tool for both the study and preparation of materials. In spi. te of the many high pressure conferences held in recent years, I felt that there was a need for scientists within a well-defined area (not bound merely by the common experimental technique) to meet in an atmosphere conducive to frank exchange and close interaction. In this spirit, the Cleveland State University hosted such a conference from July 20 to 22, 1977, in which the physics of solids under high pressures and at low tempera tures was specifically examined. Both the original and review papers presented at the conference and the candid discussions following their presentations appear in this volume. They clearly cover a rather complete spectrum of current research in the physics of solids at high pressures and low temperatures. I wish to thank the National Aeronautics and Space Administra tion, the Office of Naval Research and the National Science Founda tion for their financial support of the conference. In addition, I wish especially to thank Steinar Huang for his unceasing assistance in arranging this conference. I also wish to thank him and Francis Stephenson for their assistance in preparing this book. C. W.

Taschenbuch. Condizione: Neu. Neuware -This book, written by the eminent Russian organic chemist Professor M. G. Voronkov, exhaustively deals with the reactions of sulfur with organic compounds. It is the only book on the subject which covers both work readily available to Western scientists and research carried out by Russian workers. Since much of the work discussed in this volume is not readily accessible to Western scien tists, it will enable them to find hitherto 'unpublished' research. In addition, Professor Voronkov has dealt with many reactions and processes of interest to the industrial chemist; e.g., there is an interesting section on sulfur dyes and related compounds, and the chemistry of vulcanization is lucidly discussed. Hence this book should be of value to both academic and industrial chemists inter ested in the chemistry and reactions of sulfur, and also to those synthetic chemists studying new pathways to organic compounds. The text has recently been updated and revised, and there are numerous references to publications up to and including 1980. An exhaustive index is provided to enable the reader to refer rapidly to any of the compounds, reactions, or processes discussed in the text.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 444 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The present NATO Advanced Study Institute held in CARGESE (Corsica) from Au gust 8th to August 18th, 1989 was devoted to Hadronic Physics. We tried to give this school a key educational role in this new and rapidly developing interdisciplinary field. We hope that the combination of the lectures and the open atmosphere of scientific exchange and inquiry afforded by the Cargese format has provided a unique educational and scien tific opportunity for students and has brought together all the relevant concepts and issues for frontier research in this field. We would like to express our gratitude to NATO for its generous financial support which made this Institute possible. We also wish to thank Dr. Luis V. Da Cunha, Director of the Scientific Affairs Division, for his valuable comments and advice.

Taschenbuch. Condizione: Neu. Neuware -The calculus of variations, whose origins can be traced to the works of Aristotle and Zenodoros, is now Ii vast repository supplying fundamental tools of exploration not only to the mathematician, but-as evidenced by current literature-also to those in most branches of science in which mathematics is applied. (Indeed, the macroscopic statements afforded by variational principles may provide the only valid mathematical formulation of many physical laws. ) As such, it retains the spirit of natural philosophy common to most mathematical investigations prior to this century. How ever, it is a discipline in which a single symbol (b) has at times been assigned almost mystical powers of operation and discernment, not readily subsumed into the formal structures of modern mathematics. And it is a field for which it is generally supposed that most questions motivating interest in the subject will probably not be answerable at the introductory level of their formulation. In earlier articles,1,2 it was shown through several examples that a complete characterization of the solution of optimization problems may be available by elementary methods, and it is the purpose of this work to explore further the convexity which underlay these individual successes in the context of a full introductory treatment of the theory of the variational calculus. The required convexity is that determined through Gateaux variations, which can be defined in any real linear space and which provide an unambiguous foundation for the theory. 384 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Most books on plastics machinery include a preamble on the origin of such equipment, and some even discuss the origin of plastic itself, dating back to the early 1900s and such men as Leo Baekeland - the real founder of synthetic plastics. There seems therefore, little pur pose in reiterating what has been said before and going over the same ground so adequately covered in a number of books as well as the trade press. We are indebted to the author of this excellent treatise on twin-screw extruders for getting right down to the business at hand. The author makes mention of two pioneers - Roberto Colombo and Carlo Pasquetti - who were the first to develop twin-screw ex truders. It was my good fortune to follow the work of these pioneers, and, interestingly enough, the principles were so good that their work continues to be relevant even to the advanced and more sophisticated models so well defmed in this book.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 152 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -On October 21 and 22, 1970, the Shaping and Forming Committee, Institute of Metals Division, The Metallurgical Society of AlME, held a Conference on 'The Relation Between Theory and Practice it). Metal Forming' at the Sheraton-Cleveland Hotel during the Fall Meeting of AIME in Cleveland, Ohio. This conference was devoted to recent applications of theory to metal forming to establish a milestone in the current ability to predict phenomena during deformation processing and, thereby, demonstrate the utility of theory for process design. The papers were selected by first requesting presentations of relevant recent work from 68 recognized authorities in metal forming which resulted in 17 papers. A sub sequent call for papers resulted in the submission of 19 abstracts from which 4 papers were selected. The selection criteria required that the paper coupled theory with practice, and that the work was recent, unpublished and worthy of permanent record. The selection was performed by the Conference Chairman. The papers in this volume have been organized in accordance with the following subjects: Extrusion Drawing and Sheet Metal Forming Forming Loads and Friction Workability These papers appear to assess the salient recent applications of mechanics to the deformation processing of alloys at the present time, i. e. , circa 1970, A, L.

Taschenbuch. Condizione: Neu. Neuware -Fertilization in mammals normally occUrs within the oviduct, where it is relatively inaccessible to study. However, as a result of painstaking research, most of it carried out over the last five years, this barrier to experimentation has been largely overcome by the development of in vitro fertilization techniques for at least 11 different species, including man. The result has been a rapid increase in our knowledge of the physiological and bio chemical mechanisms involved in the fertilization process. The aim of this book, which is an extension of my recent review of cell surface interactions in fertilization (Gwatkin, 1976), is to present a brief, but well documented, account of the new knowledge that has been attained. Although this book deals with mammalian fertilization mechanisms, I have included some recent experiments on am phibian and invertebrate gametes to supplement the mammalian picture. This information is particularly valuable as the rela tively large number of eggs available from these lower forms has advanced our knowledge of certain fertilization mechanisms beyond what is known in mammals. However, in the interest of brevity, I have omitted details of morphology and minor varia tions between species. For these, and other aspects not covered here, the reader is referred to the books of Austin (1965, 1968), vii viii PREFACE Austin and Short (1972), Metz and Monroy (1969), Monroy (1965), Lord Rothschild (1956a), and Zamboni (l971a).Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 172 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This volume is concerned with methods that are available for the calculation of for mation constants, in particular computational procedures. Although graphical meth ods have considerable value in the exploration of primary (raw) data they have been overtaken by computational methods, which, for the most part, take primary data and return the refined formation constants. Graphical methods are now considered com plementary to these general computational procedures. This volume brings together programs that span the lifetime of computer-assisted determination of formation constants. On one hand the reader will find listings of programs that are derived from LETAGROP (b.l961) and the GAUSS-G/SCOGS (b. 1962) families. On the other hand programs are presented that are the newest mem bers of the SCOGS lineage and from the on-going MINIQUAD series. One program is presented that describes a computational approach to the classical Hedstrom Osterberg methods; another that takes care of electrode calibration in a simple yet rigorous manner. Potentiometry and spectrophotometry are the most popular experimental tech niques for equilibrium studies, and the programs in this volume reflect this. Four programs handle potentiometric data, two will process spectrophotometric data, and one makes use of both types of data separately or in combination.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 496 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This book is the result of an informal association between the editors which extends back to 1974. At the beginning, it was a tenuous alliance between physicians in quite different medical subspecialties-urology and psychiatry. As the alliance was forged, subspecialty rivalries and mistrust were replaced by a common clinical interest in the diagnosis and treatment of erectile problems. We quickly became aware of the high prevalence of such disorders, how poorly prepared we were to make accurate and re sponsible diagnosis and treatment plans, and how complicated an etiol ogical diagnosis could prove to be. A variety of biological and psychological influences bear on sexual function, and in many clinical contexts, diagnosis and treatment planning involves consideration of complex interactive var iables. The need for an expanded multidisciplinary team became obvious. The requisite knowledge base extended across too many subspecialty boundaries, and the necessary information was not available in a conve nient source. As we began accumulating the information base, we became aware that this information might be of value to other physicians. The authors enjoy the luxury of an academic setting in which special expertise can be readily assembled. Such resources are often unavailable to the physician in practice. Thus, it is our hope that this text can serve as a multi specialty team for the physician in solo practice. R.

Taschenbuch. Condizione: Neu. Neuware -An intense charged particle beam can be characterized as an organized charged particle flow for which the effects of beam self-fields are of major importance in describing the evolution of the flow. Research employing such beams is now a rapidly growing field with important applications ranging from the development of high power sources of coherent radiation to inertial confinement fusion. Major programs have now been established at several laboratories in the United States and Great Britain, as well as in the USSR, Japan, and several Eastern and Western European nations. In addition, related research activities are being pursued at the graduate level at several universities in the US and abroad. When the author first entered this field in 1973 there was no single reference text that provided a broad survey of the important topics, yet contained sufficient detail to be of interest to the active researcher. That situation has persisted, and this book is an attempt to fill the void. As such, the text is aimed at the graduate student, or beginning researcher; however, it contains ample information to be a convenient reference source for the advanced worker.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 364 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -We are pleased to present to our readers the Proceedings of the Second International Symposium 'Proteases: Potential Role in Health and Disease' which was held in Rothenburg ob der Tauber (FRG) during May 17-20, 1987. The topics discussed included those dealing with the physiology and pathophysiology of proteases and their inhibitors, the inter actions of proteases and hormones, the kallikrein-kinin, com plement and coagulation system, the function of proteases in arthritis, malignoma, pancreatitis, intestinal tract, lung and kidney disease as well as in hypercatabolic states (acute renal failure, multiple trauma and septicemia). Furthermore some reports dealed with the role of proteases during extracorporeal circulation. The papers presented answered many questions, but raised many more concerning the significance of proteases and their in hibitors in clinical medicine. It was unfortunately impossible in this volume, to include the extended, lively and stimulating discussions which were enjoyed by the participiants during the conference. The meeting has provided a unique framework for close inter action between scientists from various disciplines, including molecular biology, biochemistry, physiology, surgery, anaesthe siology, endocrinology, hematology, pneumatology and nephrology.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 596 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -By itself or in combination with an affective disorder, early onset schizophrenia (EOS) ¿ the onset of symptoms before 18 years of age ¿ can create severe deficits in young people¿s academic performance, family and peer relationships, and even the ability to acquire new skills. The relative rarity of the condition, meanwhile, can leave school personnel unsure of how to meet ¿ or even recognize ¿ student needs.Identifying, Assessing, and Treating Early Onset Schizophrenia at School emphasizes the importance of providing teachers and students alike with the support needed to enhance academic performance and improve social skills of children and adolescents with EOS within educational settings. In addition, its evidence-based framework enables school professionals to achieve greater confidence and accuracy in identifying students with EOS and provide appropriate services, both in special education and general classes.In this authoritative and accessible volume, experts offer the most salient information on early onset schizophrenia, including:Contributing factors and risk factors.Prevalence and epidemiology.Screening and assessment procedures.Guidelines for determining eligibility for special education programs under IDEIA and Section 504.Latest findings on school-based and off-campus interventions for EOS.A useful resource appendix.Identifying, Assessing, and Treating Early Onset Schizophrenia at School gives school psychologists and allied education professionals both a practical understanding of this disabling condition and the most up-to-date strategies for providing earlier and effective interventions.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 164 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This book is a major revision and extension of my earlier book, Experimental Psychology and Human Aging, which appeared in 1982. The intervening years have seen a remarkable expansion of psychological research on human aging, especially on topics dealing with cognition. They have also seen research on cognitive aging gain increasing importance within the mainstream of basic cognitive research. As my lecture notes for my course in the psychology of aging grew, so did my apprehension regarding the task ahead of me in revis ing the first edition. The research explosion in cognitive aging forced several major changes in content from the first to the second edition. Two chapters on learning and memory in the first edition were necessarily expanded to six chapters in the present edition. Similarly, the single prior chapter on percep tion and attention became two chapters, as did the single prior chapter on thinking. Another change from the first edition is in the addition of some review of the effects of abnormal aging on various cognitive processes, parti cularly in regard to memory functioning. To keep the revision within reason able length, some sacrifices had to be made. The multiple chapters on metho dology and theory in the first edition were condensed into the present, single chapter. However, the major topics from the first edition were retained and, in fact, added to by the inclusion of important topics and issues that emerged over the past eight years.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 872 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Since the 1960s, x-ray fluorescence spectrometry (XRF), both wavelength and energy-dispersive have served as the workhorse for non-destructive and destructive analyses of archaeological materials. Recently eclipsed by other instrumentation such as LA-ICP-MS, XRF remains the mainstay of non-destructive chemical analyses in archaeology, particularly for volcanic rocks, and most particularly for obsidian. In a world where heritage and repatriation issues drive archaeological method and theory, XRF remains an important tool for understanding the human past, and will remain so for decades to come.Currently, there is no comprehensive book in XRF applications in archaeology at a time when the applications of portable XRF and desktop XRF instrumentation are exploding particularly in anthropology and archaeology departments worldwide.The contributors to this volumeare the experts in the field, and most are at the forefront of the newest applications of XRF to archaeological problems. Itcovers all relevant aspects of the field for thoseusing the newest XRF technologies to deal with very current issues in archaeology.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 252 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This self-contained textbook gives a thorough exposition of multivariable calculus. It can be viewed as a sequel to the one-variable calculus text, A Course in Calculus and Real Analysis, published in the same series. The emphasis is on correlating general concepts and results of multivariable calculus with their counterparts in one-variable calculus. For example, when the general definition of the volume of a solid is given using triple integrals, the authors explain why the shell and washer methods of one-variable calculus for computing the volume of a solid of revolution must give the same answer. Further, the book includes genuine analogues of basic results in one-variable calculus, such as the mean value theorem and the fundamental theorem of calculus.This book is distinguished from others on the subject: it examines topics not typically covered, such as monotonicity, bimonotonicity, and convexity, together with their relation to partial differentiation, cubature rules for approximate evaluation of double integrals, and conditional as well as unconditional convergence of double series and improper double integrals. Moreover, the emphasis is on a geometric approach to such basic notions as local extremum and saddle point.Each chapter contains detailed proofs of relevant results, along with numerous examples and a wide collection of exercises of varying degrees of difficulty, making the book useful to undergraduate and graduate students alike. There is also an informative section of 'Notes and Comments¿¿ indicating some novel features of the treatment of topics in that chapter as well as references to relevant literature. The only prerequisite for this text is a course in one-variable calculus.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 488 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This book explores the dynamic processes in economic systems, concentrating on the extraction and use of the natural resources required to meet economic needs. Sections cover methods for dynamic modeling in economics, microeconomic models of firms, modeling optimal use of both nonrenewable and renewable resources, and chaos in economic models.

Taschenbuch. Condizione: Neu. Neuware -Stochastic processes and diffusion theory are the mathematical underpinnings of many scientific disciplines, including statistical physics, physical chemistry, molecular biophysics, communications theory and many more. Many books, reviews and research articles have been published on this topic, from the purely mathematical to the most practical.This book offers an analytical approach to stochastic processes that are most common in the physical and life sciences, as well as in optimal control and in the theory of filltering of signals from noisy measurements. Its aim is to make probability theory in function space readily accessible to scientists trained in the traditional methods of applied mathematics, such as integral, ordinary, and partial differential equations and asymptotic methods, rather than in probability and measure theory.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 488 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This is a relatively fast paced graduate level introduction to complex algebraic geometry, from the basics to the frontier of the subject. It covers sheaf theory, cohomology, some Hodge theory, as well as some of the more algebraic aspects of algebraic geometry. The author frequently refers the reader if the treatment of a certain topic is readily available elsewhere but goes into considerable detail on topics for which his treatment puts a twist or a more transparent viewpoint. His cases of exploration and are chosen very carefully and deliberately. The textbook achieves its purpose of taking new students of complex algebraic geometry through this a deep yet broad introduction to a vast subject, eventually bringing them to the forefront of the topic via a non-intimidating style.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 344 pp. Englisch.
