Taschenbuch. Zustand: Neu. Neuware -A Structural and Vibrational Investigation into Chromyl Azide, Acetate, Perchlorate and Thiocyanate Compounds reviews the structural and vibrational properties of chromyl azide, acetate, perchlorate, and thiocyanate from a theoretical point of view by using Density Functional Theory (DFT) methods. These compounds are extensively used in organic syntheses and the study of their structure and spectroscopy has become fundamental.This book evaluates the best theoretical level and basis set to reproduce the experimental data existing for those compounds. To this end, the optimized geometries and wavenumbers for the normal modes of vibration are calculated and the obtained results are compared and analyzed. Also, the nature of the different types of bonds and their corresponding topological properties of electronic charge density are systematically and quantitatively investigated by using the NBO analysis and the atoms in molecules theory (AIM).Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 96 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Identifying ¿networked flow¿ as the key driver of networked creativity, this new volume in the Springer Briefs series deploys concepts from a range of sub-disciplines in psychology to suggest ways of optimizing the innovative potential of creative networks. In their analysis of how to support these networks, the contributing authors apply expertise in experimental, social, cultural and educational psychology. They show how developing a creative network requires the establishment of an optimal group experience in which individual intentions inform and guide collective goals.The volume represents a three-fold achievement. It develops a ground-breaking new perspective on group creativity: the notion of ¿networked flow¿ as a bridging concept linking the neuropsychological, psychological and social levels of the creative process. In addition, the authors set out a six-stage model that provides researchers with a methodological framework (also by referring to the social network analysis) for studying the creativity traditionally associated with interpersonal contexts. Finally, the book includes perceptive analysis of the novel possibilities opened up by second-generation internet technologies, particularly in social networking, that seem destined to develop and sustain online creativity. As a wide-ranging exposition of a new direction in theoretical psychology that is laden with exciting possibilities, this volume will inform and inspire professionals, scholars and students alike.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 124 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -In recent years the gastrointestinal microflora has featured strongly in scientific, veterinary and medical research. As a result it has become obvious that the gut microflora is an essential component of the healthy animal. Not only is it involved in digestion of food, it is essential for the optimal resistance to disease. The first part of this book records the research that has been done on the factors affecting colonization of the gut and the effect that the flora has on the host animal. The second part discusses the way in which this basic knowledge affects the choice of organism being used as a probiotic. The evidence for the involvement of the gut microflora in the health and well-being of the animal is incontrovertible, but the development of probiotics has been largely empirical, failing to capitalize on the relevant research data. The bringing together of the basic information on gut microecology and the development of probiotic preparations is long overdue. It is hoped that this exercise will result in a more scientific approach to probiotic development and the emergence of new and improved preparations for animals and man. The authors involved are all experts in their field and I am greatly indebted to them for their contributions to the book. R. Fuller Abbreviations used for ¿ generIc names Aspergillus A. B.

Taschenbuch. Zustand: Neu. Neuware -I am pleased to present this volume of invited reviews and research case studies, produced to mark the retirement of Professor A. G. Smith - one of the leading researchers in Holocene palaeoecology. A. G. Smith took his first degree at the University of Sheffield, graduating in 1951 with a first-class honours degree in Botany. His doctorate was awarded in 1956 for a study in late-Quaternary vege tational history, based in the Sub-Department of Quaternary Research at the University of Cambridge, under the supervision of the late Sir Harry Godwin, FRS. He then researched and taught at Queen's University, Belfast, from 1954, leading the Nuffield Quaternary Research Unit there, becoming Co-Director of the Palaeoecology Laboratory from 1964. He was appointed Professor and Head of the Department of Botany (later, Plant Science) at University College, Cardiff, in 1973, and retired from the School of Pure and Applied Biology at the renamed University of Wales College, Cardiff, in August 1991.Although his principal interests have been concerned with the post-glacial environmental history of the British Isles, Professor Smith has significantly in fluenced many researchers elsewhere in their interpretation of biological and other evidence for human modification of the natural environment.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 328 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Can the concept of culture be applied validly to another species This paper first reports (as a case study) a kind of grooming shown by wild chimpanzees which seems to be a truly social custom. The example serves to introduce the practical pitfalls and potentials of seeking to answer the question posed. Next, the paper focuses on a type of tool-use, hammer-and-anvil, which varies across populations and has important archaeological implications. Broadening further, an exhaustive catalogue of habitual tool-use across all known field-studies is presented. Finally, the evidence of regional and local patterns of tool use by wild chimpanzees is assessed. The paper then turns to mechanisms of cultural processes, especially innovation, before ending with responses to recent criticisms by the 'anti-culturalists'. If concepts such as culture are to help us understand the behavior of our nearest relations, we must avoid simplistic and sloppy extrapolation. Two long-term field studies of wild chimpanzees have proceeded in parallel in western Tanzania, and most of the published knowledge of the natural behavior of individual chimpanzees comes from these. Goodall's (1986) research group in the Gombe National Park has focussed on the Kasakela community of chimpanzees. The project begun by the African Primate Expedition at Kasoje in the Mahale Mountains, initially under the direction of Itani and later of Nishida (1968, 1990), focussed first on K Group, then later on M Group.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 488 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Printing and imaging has a major impact on everyone. From the obvious examples of newspapers, magazines and comics through to photographs, currency and credit cards, and even the less obvious example of compact discs, everyone is familiar with the end products of printing and imaging. Until recently, the major printing and imaging technologies have been impact printing and silver halide photography. Important impact printing technologies are offset lithography, gravure, flexography and screen printing. All these technologies, including silver halide photography, are mature and have changed little over the past few decades. In contrast, the phenomenal growth of silicon chip technology over the past 15 years or so has spawned a new era of printing and imaging systems, the so-called non impact (or electronic) printers. Not all the non-impact printing technologies are of equal commercial importance. Some, like diazotype and conventional photolithography, are mature and are declining in importance. Other technologies, though relatively new, have not achieved notable commercial success. Electro graphy and magnetography fall into this category. The remaining tech nologies such as optical data storage (the technology used in compact discs), thermography (the technology used in electronic photography), ink jet printing and electrophotography are the non-impact printing tech nologies that are both modern and which have achieved remarkable commercial success, especially ink-jet printing and electrophotography.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 244 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The Handbook of Democratic Government is the first compact and comprehensive data collection for 20 countries which simultaneously provides comparative and complete information on the composition of governments. Parties, ministries, portfolios, ministers and parliamentary support are listed, as well as duration, type of government and reasons for termination. The data are organised in such a manner that every researcher can use them as a basic data set, ready to be transformed according to the particular needs dictated by the research undertaken. Various levels of analysis are possible, both cross-nationally and across time, ranging from individual ministers and separate ministries to specific parties, governments or countries. Given its format, the data set is also a very useful background to the special annual issue of the European Journal of Political Research: Political Data Yearbook. It will save researchers in the field of comparative politics valuable time as it can be utilised in connection with, or in addition to other data sources.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 128 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Chemical nomenclature can be a complicated subject. As a result, most works on the subject are rather dry textbooks and primarily consist of sets of instructions on how to name chemicals. This practical book proves that chemical nomenclature can be interesting, not just a `necessary evil'.Written in a lively and engaging style by experts in their particular fields, this new book provides a general discussion on why good, clear nomenclature is needed. It introduces the reader to the various forms of nomenclature without reading like a textbook. Both `systematic' and `trivial' nomenclature systems are used widely (and interchangeably) in chemistry and this new book covers both areas. For example, systematic nomenclature in both the CAS and IUPAC styles is introduced. These systems have many similarities but important differences which the chemist should be aware of. Specialized naming systems are needed for polymers and natural products and these areas are covered in separate chapters. The naming of elements is a very topical subject at the moment and so this is included to ensure a comprehensive coverage.Covering a wide range of topics in the area of nomenclature and acting as an introduction to a varied field, this book will be of interest to industrial chemists as well as students at senior undergraduate and postgraduate level.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 264 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The book Partial Differential Equations through Examples and Exercises has evolved from the lectures and exercises that the authors have given for more than fifteen years, mostly for mathematics, computer science, physics and chemistry students. By our best knowledge, the book is a first attempt to present the rather complex subject of partial differential equations (PDEs for short) through active reader-participation. Thus this book is a combination of theory and examples. In the theory of PDEs, on one hand, one has an interplay of several mathematical disciplines, including the theories of analytical functions, harmonic analysis, ODEs, topology and last, but not least, functional analysis, while on the other hand there are various methods, tools and approaches. In view of that, the exposition of new notions and methods in our book is 'step by step'. A minimal amount of expository theory is included at the beginning of each section Preliminaries with maximum emphasis placed on well selected examples and exercises capturing the essence of the material. Actually, we have divided the problems into two classes termed Examples and Exercises (often containing proofs of the statements from Preliminaries). The examples contain complete solutions, and also serve as a model for solving similar problems, given in the exercises. The readers are left to find the solution in the exercises; the answers, and occasionally, some hints, are still given. The book is implicitly divided in two parts, classical and abstract.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 420 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The Medieval Warm Period and the Little Ice Age are widely considered to have been the major features of the Earth's climate over the past 1000 years. In this volume the issue of whether there really was a Medieval Warm Period, and if so, where and when, is addressed. The types of evidence examined include historical documents, tree rings, ice cores, glacial-geological records, borehole temperature, paleoecological data and records of solar receipts inferred from cosmogenic isotopes. Growth in the availability of several of these types of data in recent years, and technical advances in their derivation and use, warrant this state-of-the-art re-examination of Medieval Warm Period.The book will be of value to all those with an interest in the natural variability of the climate system, for example those concerned with anticipating and detecting anthropogenic climate change.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 244 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -This volume contains three invited lectures and sixteen other papers which were pre sented at the 14th International Conference on Nearrings and Nearfields held in Stellen bosch, South Africa, July 9-161997. It was also the first nearring conference to be held after the untimely death of James R Clay, who over the years had been an inspiration to many algebraists interested in nearring theory. The occasion was marked by the invitedtalk of Gerhard Betsch, which was devoted to an overview of Clay's contributions to nearring and nearfield theory. This book is affectionately dedicated to the memory of James R Clay. All the papers presented here have been refereed under the supervision of the Editorial Board: Fong Yuen, Carl Maxson, John Meldrum, GUnterPilz, Leon van Wyk and Andries van der Walt. Thanks are due to the referees and to the Editorial Board.

Taschenbuch. Zustand: Neu. Neuware -This book contains contributions from various authors on different important topics related with probabilistic methods used for the design of structures. Initially several of the papers were prepared for advanced courses on structural reliability or on probabilistic methods for structural design. These courses have been held in different countries and have been given by different groups of lecturers. They were aimed at engineers and researchers who already had some exposure to structural reliability methods and thus they presented overviews of the work in the various topics. The book includes a selection of those contributions, which can be of support for future courses or for engineers and researchers that want to have an update on specific topics. It is considered a complement to the existing textbooks on structural reliability, which normally ensure the coverage of the basic topics but then are not extensive enough to cover some more specialised aspects. In addition to the contributions drawn from those lectures there are several papers that have been prepared specifically for this book, aiming at complementing the others in providing an overall account of the recent advances in the field. It is with sadness that in the meanwhile we have seen the disappearance of two of the contributors to the book and, in fact two of the early contributors to this field.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 420 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Soft X-rays are a powerful probe of matter. They interact selectively with electrons in atoms and molecules and can be used to study atomic physics, chemical reactions, surfaces and solids, and biological entities. Over the past 20 years, synchrotrons have emerged as powerful sources of soft X-rays for experimental use. A new, third generation of synchrotron light sources is scheduled to start operation over the next few years, beginning in 1993. These facilities are distinguished by their ultra-low emittance electron beams and by their undulators -- precisely engineered magnetic devices that cause the electrons passing through them to produce highly coherent X-rays and ultraviolet light of unprecedented spectral brightness. This volume emphasizes third-generation sources that produce light in the 10 eV--10 KeV energy range. It describes potential applications ranging from the purely scientific to the commercially viable and includes chapters on the practical aspects of designing undulators and beam line optics. Unique in its coverage, the book is a vital addition to the library of any scientist who needs information on the world's most advanced imaging and spectroscopic techniques.(ABSTRACT)This volume emphasizes the applications of new third generation synchrotron radiation sources that produce light in the ultraviolet and soft X-ray range of the spectrum. The unprecedented brightness of this light enables experiments to be conducted with greatly increased spatial and spectral resolution. Scientists can exploit these properties for imaging and spectroscopic applications that until now were impossible or impractical. Prominent researchers in the field describe these applications and others made possible by the light's pulsed time structure and polarization. The volume also includes chapters on the practical aspects of designing undulators and beam line optics.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 412 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Research of the origins of life in connection with a marine environment started at the end of the seventies, when the `black smokers' in the Pacific were discovered and the Red Sea deep hydrothermal brines were found to be a fruitful environment for abiotic synthesis of life precursors. For a while this research was categorised under the heading `chemistry', but in less than a decade the topic became fully integrated into the science of 'oceanography'. The Scientific Committee on Oceanographic Research (SCOR) initiated Working Group 91: Chemical Evolution and Origin of Life in Marine Hydrothermal Systems'. This volume contains the final report of this working group.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 260 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Today, India still remains a rural agricultural country although the share of urban population has also increased but these figures do not tell the whole story. There are evidences that urban growth is dispersed and urban sprawl promotes the spread of urban land use into the rural-urban fringe.Here the attempt is to investigate the land transformation and the driving forces which were influencing the land transformation. The present study was done on peri urban interface of Aligarh city, a relatively small city, but as other north Indian cities, it is also expanding rapidly. Moreover, it too is surrounded by a populous rural area with productive and rich agricultural hinterland. Such conditions give rise to many conflicts and mutually beneficial complementarities in the rural and urban spheres.The result shows that the demand for land is high which results in informal urban development fulfilling the requirements of many of the city¿s residents. Every piece of land is a tradable commodity, and the pursuit of short-term profits is the predominant ethic. The actors in PUI are strong because it is characterized by intermixing of rural and urban activities and interests as well as the number of actors are greater than in any other area.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 104 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -A Structural and Vibrational Study of the Chromyl Chlorosulfate, Fluorosulfate and Nitrate Compounds presents important studies related to the structural and vibrational properties on the chromyl compounds based on Ab-initio calculations. The synthesis and the study of such properties are of chemical importance because the stereo-chemistries and reactivities of these compounds are strongly dependent on the coordination modes that adopt the different ligands linked to the chromyl group.In this book, the geometries of all stable structures in gas phase for chromyl chlorosulfate, fluorosulfate, and nitrate are optimized by using Density functional Theory (DFT). Then, the complete assignments of all observed bands in the infrared and Raman spectra are performed combining DFT calculations with Pulay¿s Scaled Quantum Mechanics Force Field (SQMFF) methodology and taking into account the type of coordination adopted by the chlorosulfate, fluorosulfate and nitrate ligands as monodentate and bidentate. Moreover, the force constants for each compound at the same levels of theory are calculated. As a result, the bond orders calculated and the topological properties of electronic charge density reveal the characteristics and nature of the different bonds in each structure.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 92 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Cosmetic Science has developed greatly since the publication of the 8th edition of this textbook in 1974. Although the first part of this volume still consists of chapters about product preparations in alphabetical order, each product category has been revised and updated by a specialist. An outline of the biology, structure and function of skin, hair, teeth and nails and the reasons for the need for cosmetics are given in those dealing with the relevant preparations. Throughout, the word Cosmetics includes toiletries and thus all products which protect, cleanse, adorn, and perfume the human body, and combat body odour and perspiration. The 'f' spelling for the element 'sulfur' and its derivatives has been used following the recommendations of the International Union of Pure and Applied Chemistry (IUP AC) and the decision taken by the Royal Society of Chemistry (RSC) and the British Standards Institute (BSI) to use 'f' instead of 'ph' in all their publications. This stems from the derivation of the use of the 'f' from Latin and its use in England until the 15th century.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 768 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -This special issue of the international journal of cosmic physics, Astrophysics and Space Science, contains invited contributions delivered at the Second IEEE International Workshop on Plasma Astrophysics and Cosmology, held from 10 to 12 May 1993 in Princeton, New Jersey. The Workshop was sponsored by the NSF Division of Atmospheric Sciences, NASA Headquarters, Space Physics Division, and the Nuclear and Plasma Sciences Society of the Institute of Electrical and Electronics Engineers. It was the purpose of the Workshop to update topics in Plasma Astrophysics and Cosmology presented at the First IEEE International Workshop on Plasma Cosmology, La Jolla, California, 20-22 February 1989, and to again bring together observers and theorists to discuss the related links between plasma theory and observation. Another goal of the Workshop and these proceedings was to highlight the Centennial Celebration (1896-1996) of the founding of Plasma Astrophysics and Cosmology and several papers are devoted to the history of this field of science.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 308 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -In The Foundations of Quantum Mechanics - Historical Analysis and Open Questions, leading Italian researchers involved in different aspects of the foundations and history of quantum mechanics are brought together in an interdisciplinary debate. The book therefore presents an invaluable overview of the state of Italian work in the field at this moment, and of the open problems that still exist in the foundations of the theory.Audience: Physicists, logicians, mathematicians and epistemologists whose research concerns the historical analysis of quantum mechanics.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 476 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -In June of 1996, at the idyllic seaside resort of Guarujá, Brazil, a renowned group of researchers in space and astrophysical plasmas met to provide a forum on Advanced Topics on Astrophysical and Space Plasmas at a school consisting of some 60 students and teachers, mainly from Brazil and Argentina, but also from all the other parts of the globe. The purpose was to provide an update on the latest theories, observations, and simulations of space-astrophysical plasma phenomena.The topics covered included space plasma mechanisms for particle acceleration, nonthermal emission in cosmic plasma, magnetohydrodynamic instabilities in solar, interstellar, and other cosmic objects, magnetic field line reconnection and merging, the nonlinear and often chaotic structure of astrophysical plasmas, and the advances in high performance supercomputing resources to replicate the observed phenomena. The lectures were presented by Professor Mark Birkinshaw of the Harvard-Smithsonian Center for Astrophysics and the University of Bristol; Dr Anthony Peratt, Los Alamos National Laboratory Scientific Advisor to the United States Department of Energy; Dr Dieter Biskamp of the Max Planck Institute for Plasma Physics, Garching, Germany; Professor Donald Melrose, Director, Centre for Theoretical Astrophysics, University of Sydney, Australia; Professor Abraham Chian of the National Institute for Space Research, Brazil; and Professor Nelson Fiedler-Ferrara of the University of São Paulo, Brazil.As summarized by Professor Reuven Opher, Institute of Astronomy and Geophysics, University of São Paulo, the advanced or interested student of space and astrophysical plasmas will find reference to nearly all modern aspects in the field of Plasma Astrophysics and Cosmology in the presented lectures.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 308 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The main theme in classical ring theory is the structure theory of rings of a particular kind. For example, no one text book in ring theory could miss the Wedderburn-Artin theorem, which says that a ring R is semisimple Artinian iffR is isomorphic to a finite direct sum of full matrix rings over skew fields. This is an example of a finiteness condition which, at least historically, has dominated in ring theory. Ifwe would like to consider a requirement of a lattice-theoretical type, other than being Artinian or Noetherian, the most natural is uni-seriality. Here a module M is called uni-serial if its lattice of submodules is a chain, and a ring R is uni-serial if both RR and RR are uni-serial modules. The class of uni-serial rings includes commutative valuation rings and closed under homomorphic images. But it is not closed under direct sums nor with respect to Morita equivalence: a matrix ring over a uni-serial ring is not uni-serial. There is a class of rings which is very close to uni-serial but closed under the constructions just mentioned: serial rings. A ring R is called serial if RR and RR is a direct sum (necessarily finite) of uni-serial modules. Amongst others this class includes triangular matrix rings over a skew field. Also if F is a finite field of characteristic p and G is a finite group with a cyclic normal p-Sylow subgroup, then the group ring FG is serial.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 240 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Exploiting new advanced structures and electromechanical systems, e. g. , adaptive structures, high-precision systems, micro electromechanical systems, distributed sensors/actuators, precision manipulation and controls, etc. , has been becoming one of the mainstream research and development activities (structure & motion) in recent years. These new systems and devices could bring a new technological revolution in modern industries and further, directly or indirectly, impact human life. In the search for and research in innovative technologies, it is proved that piezoelectric materials are very versatile in both sensor and actuator applications. Consequently, piezoelectric technology has been widely applied to a large number of industrial applications and devices, varying from thin-film micro sensors/actuators to large space structures in addition to those relatively conventional applications, e. g. , sensors, actuators, hydrophones, precision manipulators, mobile robots, micro motors, etc. There have been a few books on piezoelectricity published in the past; however, a unified presentation of piezoelectric shells and distributed senSing/control applications is still lacking. This book is intended to fill the gap and to pro~de practising engineers and researchers with an introduction to advanced piezoelectric shell theories and distributed sensor/actuator technologies in structural identification and control. This book represents a collection of the author's recent research and development on piezoelectric shells and related applications to distributed measurement and control of continuaj it reflects six best-paper awards, including [ xviii] ¿ Contents. two ASME Best-Paper Awards in recent years.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 500 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Considerable advances have been made in our understanding of the eukaryotic cell cycle at the molecular level over the past two decades or so, particularly in yeast and in animal systems. However, only in the past three or four years has progress been made in plants at the molecular level. The present volume brings together molecular biologists, cell biologists and physiologists to discuss this recent progress and how it relates to our understanding of the regulation of plant growth and development. The opening paper summarises the progress which has been made with fission yeast. Subsequent papers explore what is known about cell cycle control at the molecular level in plants, and about cell cycle regulation in specific physiological systems, ending with summary papers on cell division in roots and shoots. The book comprises up-to-date findings on a fundamental aspect of plant growth and development, and as such will be of particular interest to advanced undergraduates, postgraduates and research scientists in the fields of molecular biology, cell biology and physiology.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 232 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The subject of this book is connected with a new direction in mathematics, which has been actively developed over the last few years, namely the field of polynomial computer algebra, which lies at the intersection point of algebra, mathematical analysis and programming. There were several incentives to write the book. First of all, there has lately been a considerable interest in applied nonlinear problems characterized by multiple sta tionary states. Practical needs have then in their turn led to the appearance of new theoretical results in the analysis of systems of nonlinear algebraic equations. And finally, the introduction of various computer packages for analytic manipulations has made it possible to use complicated elimination-theoretical algorithms in prac tical research. The structure of the book is accordingly represented by three main parts: Mathematical results driven to constructive algorithms, computer algebra realizations of these algorithms, and applications. Nonlinear systems of algebraic equations arise in diverse fields of science. In particular, for processes described by systems of differential equations with a poly nomial right hand side one is faced with the problem of determining the number (and location) of the stationary states in certain sets.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 260 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The provision of optimal dialysis therapy to children requires a thorough understanding of the multi-disciplinary manner in which the pediatric patient is affected by renal insufficiency. Knowledge of the technical aspects of peritoneal dialysis, hemodialysis and continuous renal replacement therapy must be complemented by attention to issues such as anemia, renal osteodystrophy, hypertension, growth, cognitive development, nutrition, nursing care and the psychosocial adaptation of the child and family to chronic disease.The inaugural edition of Pediatric Dialysis provides a comprehensive review of these and other related topics with a singular emphasis on the unique aspects of their application to children. With authoritative, clinically relevant, well-referenced chapters written by a host of recognized international experts who emphasize key aspects of contemporary management, Pediatric Dialysis has been designed to serve as a primary resource to all clinicians involved in the care of the pediatric dialysis patient.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 680 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -A. K. TURNER Department of Geology and Geological Engineering Colorado School of Mines Golden, Colorado 80401 USA Geology deals with three-dimensional data. Geoscientists are concerned with three dimensional spatial observations, measurements, and explanations of a great variety of phenomena. The representation of three-dimensional data has always been a problem. Prior to computers, graphical displays involved specialized maps, cross-sections, fence diagrams, and geometrical constructions such as stereonets. All were designed to portray three-dimensional relationships on two-dimensional paper products, and all were time consuming to develop. Until recently, computers were of little assistance to three-dimensional data handling and representation problems. Memory was too expensive to handle the huge amounts of data required by three-dimensional assessments; computational speeds were too slow to perform the necessary calculations within a reasonable time; and graphical displays had too Iowa resolution or were much too expensive to produce useful visualizations. Much experience was gained with two-dimensional geographic information systems (GIS), which were applied to many land-use management and resource assessment problems. The two-dimensional GIS field matured rapidly in the late 1980's and became widely accepted. The advent of the modern computer workstation, with its enhanced memory and graphical capabilities at ever more affordable prices, has largely overcome these earlier constraints.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 468 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Researchers in the natural sciences are faced with problems that require a novel approach to improve the quality of forecasts of processes that are sensitive to environmental conditions. Nonlinearity of a system may significantly complicate the predictability of future states: a small variation of parameters can dramatically change the dynamics, while sensitive dependence of the initial state may severely limit the predictability horizon. Uncertainties also play a role.This volume addresses such problems by using tools from chaos theory and systems theory, adapted for the analysis of problems in the environmental sciences. Sensitive dependence on the initial state (chaos) and the parameters are analyzed using methods such as Lyapunov exponents and Monte Carlo simulation. Uncertainty in the structure and the values of parameters of a model is studied in relation to processes that depend on the environmental conditions.

Taschenbuch. Zustand: Neu. Neuware -Plant Production on the Threshold of a New Century describes and compares problems and frontier developments in the different sectors of plant production, integrating developments in basic plant sciences, crop science and socioeconomic science, leading to sustainable plant production. Hence the book formulates goals and constraints in policy, economy, production, environment and land use; indicates how these goals and constraints may be translated into farming styles and cropping systems; and describes how the fundamental plant sciences can contribute to the implementation of such farming styles and cropping systems.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 516 pp. Englisch.
