Buch. Zustand: Neu. Neuware -This monograph is intended as a concise and self-contained guide to practitioners and graduate students for applying approaches in computational fluid dynamics (CFD) to real-world problems that require a quantification of viscous incompressible flows. In various projects related to NASA missions, the authors have gained CFD expertise over many years by developing and utilizing tools especially related to viscous incompressible flows. They are looking at CFD from an engineering perspective, which is especially useful when working on real-world applications. From that point of view, CFD requires two major elements, namely methods/algorithm and engineering/physical modeling. As for the methods, CFD research has been performed with great successes. In terms of modeling/simulation, mission applications require a deeper understanding of CFD and flow physics, which has only been debated in technical conferences and to a limited scope. This monograph fills the gap by offering in-depth examples for students and engineers to get useful information on CFD for their activities. The procedural details are given with respect to particular tasks from the authors¿ field of research, for example simulations of liquid propellant rocket engine subsystems, turbo-pumps and the blood circulations in the human brain as well as the design of artificial heart devices. However, those examples serve as illustrations of computational and physical challenges relevant to many other fields. Unlike other books on incompressible flow simulations, no abstract mathematics are used in this book. Assuming some basic CFD knowledge, readers can easily transfer the insights gained from specific CFD applications in engineering to their area of interest.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 304 pp. Englisch.

Buch. Zustand: Neu. Neuware -The papers that comprise this book could hardly been conceived of 10 years ago. The idea of commercial republics having a positive impact on peaceful international relations was, of course, not new. Kant and Montesquieu argued for the idea and the idea that trade and peace might be linked has been standard political rhetoric in the west for decades. These were macro-level analyses of commerce and peace.This remains a field in its infancy and this book provides a foundation for further in-depthanalysis and inquiry.Previously published in the Journal of Business Ethics, Volume 89 Supplement 4, 2009Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 276 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -South Asia is home to a diverse range of prehistoric and contemporary cultures that include foragers, pastoralists, and farmers. In this book, archaeologists, biological anthropologists, geneticists and linguists are brought together in order to provide a comprehensive account of the history and evolution of human populations residing in the subcontinent. A wide range of topics and issues are addressed in this book, including hominin adaptations, behaviours, and dispersals; the origin and spread of food producing economies; and the cultural, biological and genetic relationship of foragers and settled communities. New theories, methodologies and interpretations presented in this book are bound to have a profound effect on the way in which the cultural record of South Asia is perceived and how this evolutionary history relates to events in the wider world.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 480 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Over the past decade there has been an increasing demand for suitable material in the area of mathematical modelling as applied to science and engineering. There has been a constant movement in the emphasis from developing proficiency in purely mathematical techniques to an approach which caters for industrial and scientific applications in emerging new technologies. In this textbook we have attempted to present the important fundamental concepts of mathematical modelling and to demonstrate their use in solving certain scientific and engineering problems. This text, which serves as a general introduction to the area of mathematical modelling, is aimed at advanced undergraduate students in mathematics or closely related disciplines, e.g., students who have some prerequisite knowledge such as one-variable calculus, linear algebra and ordinary differential equations. Some prior knowledge of computer programming would be useful but is not considered essential. The text also contains some more challenging material which could prove attractive to graduate students in engineering or science who are involved in mathematical modelling. In preparing the text we have tried to use our experience of teaching mathematical modelling to undergraduate students in a wide range of areas including mathematics and computer science and disciplines in engineering and science. An important aspect of the text is the use made of scientific computer software packages such as MAPLE for symbolic algebraic manipulations and MA TLAB for numerical simulation.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 304 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Ancient China was outstanding in mechanical technology before the 15th century. Numerous ingenious machines were invented. However, due to incomplete documentation and loss of finished objects, most of the original machines cannot be verified and many of the inventions did not pass down to later generations. This book, based on the author¿s research and teaching experiences over the last 20 years, is devoted to presenting an innovative methodology in the area of mechanical historiography for the systematic reconstruction design of ancient Chinese machines that have been lost to time. Its purpose is to generate all possible design concepts of lost machines. If the defined and/or concluded design specifications, topological characteristics, and - sign requirements and constraints are feasible, one of the resulting rec- struction designs should be the original design. Such an approach provides a logical tool for historians in ancient mechanical engineering and techn- ogy to further identify the possible original designs according to proven historical archives. However, this work will not deal with the credibility of historical literary works. It supposes that the lost machines existed, and tries to demonstrate the feasibility of reconstructing the lost designs. The book is organized in such a way that it can be used for teaching, research or self-study. Chapter 1 introduces the study, classifications, and process for the reconstruction design of ancient machinery.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 324 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -This is the first of two volumes introducing structural and continuum mechanics in a comprehensive and consistent way. The current book presents all theoretical developments both in text and by means of an extensive set of figures. This same approach is used in the many examples, drawings and problems. Both formal and intuitive (engineering) arguments are used in parallel to derive the principles used, for instance in bending moment diagrams and shear force diagrams. A very important aspect of this book is the straightforward and consistent sign convention, based on the stress definitions of continuum mechanics. The book is suitable for self-education.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 796 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Forest mensuration is one of the most fundamental disciplines within forest and related sciences. It deals with the measurement of trees and stands and the analysis of the resultant information. During the early days of sustained forest management simple measurement and estimation methods and with the analysis of inventory and research data were available. The middle of last c- tury, however, witnessed a worldwide increase in the need for more quan- tative information about trees and stands. This generated the need for more sophisticated methods to obtain and analyze forest data. This development was followed by a phenomenal explosion of information. During the past decades there has been fruitful cooperation between the Institute of Forest Inventory and Forest Growth, formerly ¿Institute of Forest Management and Forest Yield Sciences¿ of the University of Gottingen, ¿ Germany and the Faculty of Forestry of the University of Stellenbosch, South Africa. This book is one of the results of this fruitful cooperation between these institutions.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 404 pp. Englisch.

Buch. Zustand: Neu. Neuware -'Adhesion of Cells, Viruses and Nanoparticles' describes the adhesion of cells, viruses and nanoparticles starting from the basic principles of adhesion science, familiar to postgraduates, and leading on to recent research results.The underlying theory is that of van der Waals forces acting between cells and substrates, embodied in the molecules lying at the surfaces, together with the geometry and elasticity of the materials involved.The first part describes the fundamental background to adhesion principles, including the phenomenology, the important equations and the modeling ideas. Then the mechanisms of adhesion are explored in the second part, including the elastic deformations of spheres and the importance of the energy of adhesion as measured in various tests. It is demonstrated that adhesion of cells is statistical and depends on Brownian movement and on the complex multiple contacts that can form as cells move around. Then, detailed chapters on cell adhesion, contact of viruses and aggregation of nanoparticles follow in Part 3. Finally, the last chapter looks to the future understanding of cell adhesion and points out some interesting directions of research, development and treatment of diseases related to these phenomena.This book is an ideal resource for researchers on adhesion molecules, receptors, cell and tissue culturing, virus infection, toxicity of nanoparticles and bioreactor fouling. It can also be used to support undergraduate and Masters level teaching courses.'This is a fascinating book and it is an invaluable resource for understanding particle-particle/surface adhesion at micro- and nano- scales. I intend to keep one for my future reference and highly recommend it to my students.'(Prof. Zhibing Zhang, School of Chemical Engineering, University of Birmingham, UK)Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 300 pp. Englisch.

Buch. Zustand: Neu. Neuware -Viewed as a flashpoint of the Scientific Revolution, early modern astronomy witnessed a virtual explosion of ideas about the nature and structure of the world. This study explores these theories in a variety of intellectual settings, challenging our view of modern science as a straightforward successor to Aristotelian natural philosophy. It shows how astronomers dealt with celestial novelties by deploying old ideas in new ways and identifying more subtle notions of cosmic rationality. Beginning with the celestial spheres of Peurbach and ending with the evolutionary implications of the new star Mira Ceti, it surveys a pivotal phase in our understanding of the universe as a place of constant change that confirmed deeper patterns of cosmic order and stability.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 196 pp. Englisch.

Buch. Zustand: Neu. Neuware -Heavy metals can be emitted into environment by both natural and anthropogenic sources, mainly mining and industrial activity. Human exposure occurs through all environmental media. Infants are more susceptible to the adverse effects of exposure. Increasing attention is now being paid to the mental development of children exposed to heavy metals. The purpose of this book is to evaluate the existing knowledge on intellectual impairment in children exposed to heavy metals in their living environment and to identify the research needs in order to obtain a clearer picture of the situation in countries and regions at risk, in which the economy is closely related to metallurgy and heavy metals emission, and to recommend a strategy for human protection. In greater detail the main objectives could be formulated as follows: to review the principal sources of single, and complex mixtures of, heavy metal pollutants in the environment; to identify suitable methodology for chemical analyses in the environment and in humans; to evaluate the existing methods for measuring mental impairment, including their reliability and validity; to recommend a standard testing protocol to be used in future research; to assess the future role of environmental heavy metal pollution in countries and regions at risk and its effects on children¿s neurological development; to recommend a prevention strategy for protecting children¿s health and development.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 364 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -For centuries people have been puzzled by the inevitability of human aging. For most of the second half of the twentieth century aging remained a mystery, or an unsolved biological problem. At the end of the 20th century a remarkable scientific discovery emerged. It was not a single discovery in the usual sense, because it was based on a series of important interconnected insights over quite a long period of time. These insights made it possible for the very first time to understand the biological reasons for aging in animals and man. It can already be said, however, that the many observations and insights that explain aging will not be accepted as established knowledge for a long time. The field is still full of scientists, and non-scientists, who are just happy to go on speculating about the 'mystery' of aging. The aim of this book is to dispel ignorance by explaining in non-technical language what are the reasons for aging and the myth of excessive prolongation of life.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 148 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Broadband Opto-Electrical Receivers in Standard CMOS starts from the basic fundamentals necessary for the design of opto-electronic interface circuits. The book continues with an in-depth analysis of the photodiode, transimpedance amplifier (TIA) and limiting amplifier (LA). To thoroughly understand the light detection mechanisms in silicon, first a one-dimensional and second a two-dimensional model is developed. Analytical design equations are derived to guide the design of the amplifying circuits. For the TIA, the focus is on the sensitivity-speed trade-off. For the LA, a high gain-bandwidth is pursued. Several practical design examples reveal the subtleties and challenges encountered during the design of high-performance analog circuits.Broadband Opto-Electrical Receivers in Standard CMOS covers the total design flow of monolithic CMOS optical receivers. All material is experimentally verified with several CMOS implementations, with ultimately a fully integrated Gbit/s optical receiver front-end including photodiode, TIA and LA.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 196 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -As a natural continuation of the first volume of Algebras, Rings and Modules, this book provides both the classical aspects of the theory of groups and their representations as well as a general introduction to the modern theory of representations including the representations of quivers and finite partially ordered sets and their applications to finite dimensional algebras.Detailed attention is given to special classes of algebras and rings including Frobenius, quasi-Frobenius, right serial rings and tiled orders using the technique of quivers. The most important recent developments in the theory of these rings are examined.The Cartan Determinant Conjecture and some properties of global dimensions of different classes of rings are also given. The last chapters of this volume provide the theory of semiprime Noetherian semiperfect and semidistributive rings.Of course, this book is mainly aimed at researchers in the theory of rings and algebras but graduate and postgraduate students, especially those using algebraic techniques, should also find this book of interest.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 412 pp. Englisch.

Buch. Zustand: Neu. Neuware -This book on network ethics offers 15 scholarly chapters from a variety of disciplines and fields of study, all aimed at exploring some important aspect of how networks develop, enact, and enforce ethical norms. The chapters are ordered according to the levels of analysis each deals with, ranging from the cognitive/intrapersonal to the systemic/societal. Taken together, these chapter provide a fresh look at how networks are changing the way business is done and the way we think about ethics. Earlier versions of some chapters in this book were presented at the Conference ¿¿Network Ethics:The New Challenge in Business, ICT and Education,¿¿ hosted by the Center for Ethics, Business and Economics of the School of Business and Economics of the Catholic University of Portugal, in collaboration with Carnegie Mellon University and the University of Northern Iowa.Previously Published in the Journal of Business Ethics, Volume 90 Supplement 4, 2009Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 248 pp. Englisch.

Buch. Zustand: Neu. Neuware -Recent trends in globalization have conclusively demonstrated that economic and socio-political problems of the 21st century would need to be confronted in the context of the inter-dependent nature of the world and its inhabitants. The emerging global economic order has once again brought capitalism and its principal actor, the large multinational corporation, to the apex of social institutions.The 23 papers represent a diversity of viewpoints and are indicative of one of the major goals, i.e., to create a meaningful discourse that goes beyond rhetoric. Instead, it emphasizes a search for feasible solutions in the context of real world problems, resource constraints, and human frailties.Previously Published in the Journal of Business Ethics, Volume 87 Supplement 1, 2009Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 372 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -One goal of epistemology is to refute the skeptic. Another, with an equally dist- guished if briefer pedigree, is to make sense of science as a knowledge-acquiring enterprise. The goals are incompatible, in that the latter presupposes that the skeptic is wrong. The incompatibility is not strict. One could have both goals, conditi- ing the latter upon success at the former. In fact, however, epistemologies aimed at the skeptic tend not to get anywhere near science. They¿ve got all they can handle guring out how we can know we have hands. I come to epistemology from the philosophy of science, my original interest in which was epistemological. Philosophers of science are concerned with epistemic justi cation, but their question about it is how far it extends. They take justi cation to be unproblematic at the level of ordinary experience; their worries begin with the interpretation of experience as evidence for theory. They are interested in the scope of scienti c knowledge. Having taken a position on this question (1997), - guing that justi cation extends to theoretical hypotheses, I came to wonder about the nature of justi cation generally. This is not a belated discovery of the skeptical problem or a reconsideration of what I took to be unproblematic. It is simply an interest in the possibility of locating epistemic advance in science within a broader understanding of the nature of epistemic justi cation. Now that I know that just- cation extends to theory, I am taking a step back and asking what justi cation is.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 228 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -With some exceptions, there is not a real interest in Islamic philosophy and t- ology in Western institutions today. This largely ignored area has the potential to present enlightening insights into the development of the Western thought and to contribute to contemporary discussions in philosophy and theology in general. Scholars working in Islamic thought usually focus on its medieval background and consider it to be mainly of a historical interest and far away from the intellectual world of today. Showing its contemporary relevance is an important task by which the status of Islamic philosophy can be elevated to its proper station. By considering these points in mind, the University of Kentucky organized an international graduate student conference on Islamic philosophy and the- ogy with an emphasis on its contemporary relevance which was held between the 28th and 30th September 2007. This book emerged out of the conf- ence by adding more chapters relevant to the main theme of the book. This book presents analyses and discussions of different topics in Islamic philo- phy and theology by relating them to contemporary debates and ideas in four main areas: epistemology, metaphysics, philosophy of religion and value t- ory. There are ten chapters in sum. Some of the chapters are written by graduate students and some of them by experienced scholars. Each chapter presents c- siderable insight into its relevant topic but does not represent the opinion of anybody except the author.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 200 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -This book traces progress in photography since the first pinhole, or camera obscura, architecture. The authors describe innovations such as photogrammetry, and omnidirectional vision for robotic navigation. The text shows how new camera architectures create a need to master related projective geometries for calibration, binocular stereo, static or dynamic scene understanding. Written by leading researchers in the field, this book also explores applications of alternative camera architectures.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 380 pp. Englisch.

Buch. Zustand: Neu. Neuware -The dilemma facing Cyprus-that of limited water supplies (both in terms of quantity and quality) in the face of steadily increasing water demand, coupled with a fragmented institutional structure of the water sector-is characteristic of most arid and semi-arid countries all over the world. Another common characteristic of Cyprus is that the water management administrative boundaries there do not coincide with the hydrological ones, while the ongoing political problem of the island creates significant administration problems.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 180 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Economic dimensions have been somewhat neglected in research on nature policy and management of marine ecosystem exploitation. The current book aims to ll this gap. It examines the mismatches of natural, socio-economic, and regulatory processes and regimes in time and space. This involves dealing with the complexity and uncertainty that are inherent to the interaction of marine ecosystems and economic systems. The approach adopted is based on the idea that the design of sustainability policies requires an integration of insights from resource, environmental, and ecological economics on theonehandandmarinebiologyandenvironmentalsciencesontheotherhand.Forthis purpose, use is made of integrated assessment on the basis of theoretical and applied mathematical models. The book is the result of a large project, hosted by the Department of Spatial E- nomics of the Free University in Amsterdam, under the supervision of the rst author. TheprojectreceivedfundingfromtheNetherlandsOrganisationforScienti cResearch (NWO), through a ¿priority program¿titled¿SustainableUseandConservationof- rine Living Resources,¿ which was initiated and coordinated by Prof. Wim Wolff of the University of Groningen. The work reported here has greatly bene ted from external advice given by marine biologists who participated in this research program.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 272 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -'A system is just like truth's tail, but the truth is like a lizard. It will leave the tail in your hand and escape; it knows that it will soon grow another one.' [Ivan Sergeevich Turgenev (1818-1883), Letter, Paris, January 3, 1857, to Count Lev Nikolaevich Tolstoy. Turgenev: Letters, ed. David].a scientist can only come to a partial understanding of industrial transformation processes. This is so not only because of the vastness of the topic, but because of the inherent limitations of each scientific discipline. The common ground, which scientists of different disciplines may endeavour to find when approaching some problem, is often slight.A scientist entering such grounds runs the risk of getting lost, losing understanding and only catching the loose tail mentioned above. Secondly, sciences, to make a difference, must impress their importance upon the public and convince scientific and policy institutions in order to obtain the means to carryout their mission.The editors consider that there has been progress, and that this book is a sign of such progress, and hope that it provides a further contribution to such advancement. Their hope is that this book will also foster co-operation among those approaching this area from dissimilar disciplines and scientific traditions, and that it will stimulate progress for all scientists advancing on the international road to global sustainability.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 248 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -A Sea Change in a Changing Sea The oceans, seas and coastal areas encompass over 70% of the earth¿s surface. They are a critical driver of the earth¿s hydrologic cycle and climate system, important for c- merce, transport, and tourism, a source of economically important living marine resources, minerals such as hydrocarbons, as well as new pharmaceutical compounds. The marine environment provides essential habitats for thousands of marine living 1 2 resources, which in turn contribute significantly to global food security, employment, 3 and trade. Overall, the seäs contribution to human welfare, in terms of market and non-market resources and environmental services, has been estimated at US$21 trillion/year (Costanza, 2000). However, despite the importance of the ocean realm to humans, there is a growing sense that human impacts are destabilizing this system. Some experts believe that current fishing levels are approaching or exceeding the total 4 productivity of the ocean ecosystem (National Research Council, 1999).Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 240 pp. Englisch.

Buch. Zustand: Neu. Neuware -Landscape Development and Climate Change in Southwest Bulgaria aims to address some of the current limitations in our understanding of past Balkan climate and environment. High mountains and their ecosystems offer an outstanding opportunity for studies on the impact of climate change.The Balkan Mountains in Southeast Europe, situated at the transition between temperate and Mediterranean climate, are considered as very sensitive to historical and current global changes. The geoarchives lake sediment, peat and soil, long living trees and glaciers have been used to reconstruct the climatically-driven change of forest and treeline during the Holocene and the younger past. These processes are interrelated with complex ecological changes, as for example the seasonality of climate parameters. The landscape research approach with the analyses through multi-palaeo-geoecological proxies is new for the Balkans.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 172 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Cancer cells are continuously interacting with the immune system of the host. These interactions can be regarded as a double edged sword. On the one hand, innate and adaptive immune responses act to protect the host by attempting rejection of the tumor. On the other hand, inflammatory cells and proteins stimulate multiplication and dissemination of cancer cells, thereby accelerating the progression of the disease. Traditionally, the interplay between cancer cells and host immunity has been studied systemically, with no particular attention to the site at which a given tumor develops. Recent studies, however, indicate that the tumor microenvironment is unique in providing both supportive and inhibitory factors that determine the fate of the tumor and its host. Accordingly, microenvironmental immunity that operates inside and around a tumor plays a crucial role in cancer development and progression. The aim of the present volume is to compile reviews on innate and adaptive immune responses at the tumor microenvironment with emphasis on positive and negative outcomes that affect the progression of the disease. These reviews have been solicited from experts in the field who published original research studies focusing on these issues.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 224 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The journal Boundary-Layer Meteorology was started in 1970 and has become the premier vehicle for the publication of research papers in its field. Dr R.E. Munn served as Editor-in-Chief until recently. The special 25th Anniversary volume, on which this book is based, was compiled from review and other articles solicited and selected as a `Festschrift' to honour Ted Munn's achievement as editor of the journal over that time. Articles by leading contributors to the field include reviews of field studies (Askervein, HEXOS, Cabauw) and their impacts; numerical modelling (large-eddy simulation of the surface layer, frontal structures); analyses and critical discussions (of the von Karman constant, bulk aerodynamic formulations, air-sea interaction, vegetation canopies); and reviews or previews of progress in our understanding of the atmospheric boundary layer, turbulence simulation, Lagrangian descriptions of turbulent diffusion and remote sensing of the boundary layer. The collection provides an excellent perspective on the state of the subject and where it is headed. It should provide fascinating and stimulating reading for researchers and students of boundary-layer meteorology and related areas.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 424 pp. Englisch.
