Taschenbuch. Condizione: Neu. Neuware -Hungry Hollow is simply an ordinary creek winding through about a mile of ordinary forest and meadow somewhere east of the Rocky Mountains. But like all such places, it is also a vast and intricate web of life with extensions that reach around the planet, back into prehistoric time, and within to a teeming, bizarre microscopic world. In dozens of short, wonderfully imaginative chapters, A.K. Dewdney introduces us to the denizens of this world. We encounter a hackberry tree whose branches perfectly reproduce the taxonomic Tree of Life, learn how it would look and feel to shrink by stages to the size of an amoeba while swimming in a river, watch a toad win the lottery, and see the world of Hungry Hollow from the viewpoint of bears, earthworms, and even stones. This is an excursion into natural history like no other.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 252 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Colpiscono circa 170 mila italiani, con un trend in forte ascesa. Si chiamano Malattia di Crohn e colite ulcerosa: malattie autoimmuni, ovvero causate da un errore del sistema immunitario che si scatena contro se stesso. Perché Come fermare questa furia distruttiva Sono stati fatti grandi passi avanti ma molto resta ancora da scoprire e molte sono le questioni controverse: dalle cause della malattia ai metodi di diagnosi più tempestiva, alle terapie. Le malattie autoimmuni dell'intestino colpiscono in giovane età, tra i 15 e i 45 anni, hanno un impatto molto negativo sulla qualità della vita di chi si ammala e pongono questioni di primissimo piano: come si convive con una diagnosi di questo tipo, qual è il migliore accesso alle cure, quali le disposizioni di legge che facilitano la vita dei malati. Questo libro vuole raccontare la vita e la battaglia quotidiana delle persone colpite da queste malattie, le scelte che devono fare e gli ostacoli che si trovano ad affrontare, dal punto di vista di uno dei massimi esperti mondiali della materia, Silvio Danese, e da quello di un giovane paziente, Marco Greco, che ha trasformato la sua lotta quotidiana in una battaglia condotta a nome di tutti i malati. Gettando luce su uno dei più straordinari misteri della medicina moderna, le malattie autoimmuni, questo volume affronta senza omissioni il grande tema sanitario dell¿Italia di oggi, la cronicità, la condizione sociale e medica di milioni di persone costrette a convivere con la malattia per decenni. 108 pp. Italienisch.

Taschenbuch. Condizione: Neu. Neuware -From the editors of the wildly successful Beyond Calculation comes another exploration of the overwhelming impact of computers on our future. This time, the essays focus on the human impact of computer technology and culture: how computers will affect the ways we teach, learn, communicate, relate to each other, and live in the coming decades. The contributors, representing the best of many fields, include Secretary of Defense William Perry on how computers will affect warfare; Brian Ferrin on technology and storytelling; Patti Maes on intelligent agents; Nobel Laureate Murray Gell-Mann on the quality of information; Eliot Soloway on the impact of computers on education; and many more. Like Beyond Calculation, praised by the New York Times for its 'astonishing intellectual reach,' this sequel engages readers with some of the most compelling and important issues of our time.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 220 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Da quando è iniziata la rivoluzione della fotografia digitale, con i sensori CCD che hanno soppiantato la pellicola, qualsiasi appassionato del cielo, dotandosi di una strumentazione non particolarmente costosa, può diventare esploratore attivo dell¿immensità della volta celeste, potenzialmente un vero e proprio astronomo.In questo libro, l¿autore mostra quanto è possibile ottenere (ed è tanto!) nello studio del cielo con un telescopio amatoriale di soli 25 cm di diametro, anche attraverso tecniche di ripresa innovative, come la fotografia dei pianeti fatta in pieno giorno, o la ripresa di dettagli della superficie di Venere, nonostante il fatto che il pianeta sia perennemente avvolto da una coltre impenetrabile di nubi. 200 pp. Italienisch.

Taschenbuch. Condizione: Neu. Neuware -This lecture provides an introduction to cyber foraging, a topic that lies at the intersection of mobile and cloud computing. Cyber foraging dynamically augments the computing resources of mobile computers by opportunistically exploiting fixed computing infrastructure in the surrounding environment. In a cyber foraging system, applications functionality is dynamically partitioned between the mobile computer and infrastructure servers that store data and execute computation on behalf of mobile users. The location of application functionality changes in response to user mobility, platform characteristics, and variation in resources such as network bandwidth and CPU load. Cyber foraging also introduces a new, surrogate computing tier that lies between mobile users and cloud data centers. Surrogates are wired, infrastructure servers that offer much greater computing resources than those offered by small, battery-powered mobile devices. Surrogates are geographically distributed to be as close as possible to mobile computers so that they can provide substantially better response time to network requests than that provided by servers in cloud data centers. For instance, surrogates may be co-located with wireless hotspots in coffee shops, airport lounges, and other public locations. This lecture first describes how cyber foraging systems dynamically partition data and computation. It shows how dynamic partitioning can often yield better performance, energy efficiency, and application quality than static thin-client or thick-client approaches for dividing functionality between cloud and mobile computers. The lecture then describes the design of the surrogate computing tier. It shows how strong isolation can enable third-party computers to host computation and store data on behalf of nearby mobile devices. It then describes how surrogates can provide reasonable security and privacy guarantees to the mobile computers that use them. The lecture concludes with a discussion of data staging, in which surrogates temporarily store data in transit between cloud servers and mobile computers in order to improve transfer bandwidth and energy efficiency.

Taschenbuch. Condizione: Neu. Neuware -Although the solar energy industry has experienced rapid growth recently, high-level management of photovoltaic (PV) arrays has remained an open problem. As sensing and monitoring technology continues to improve, there is an opportunity to deploy sensors in PV arrays in order to improve their management. In this book, we examine the potential role of sensing and monitoring technology in a PV context, focusing on the areas of fault detection, topology optimization, and performance evaluation/data visualization. First, several types of commonly occurring PV array faults are considered and detection algorithms are described. Next, the potential for dynamic optimization of an array's topology is discussed, with a focus on mitigation of fault conditions and optimization of power output under non-fault conditions. Finally, monitoring system design considerations such as type and accuracy of measurements, sampling rate, and communication protocols are considered. It is our hope that the benefits of monitoring presented here will be sufficient to offset the small additional cost of a sensing system, and that such systems will become common in the near future.

Taschenbuch. Condizione: Neu. Neuware -In February 1996, a chess-playing computer known as Deep Blue made history by defeating the reigning world chess champion, Gary Kasparov, in a game played under match conditions. Kasparov went on to win the six-game match 4-2 and at the end of the match announced that he believed that chess computing had come of age. This book provides an enthralling account of the match and of the story that lies behind it: the evolution of chess-playing computers and the development of Deep Blue. The story of chess-playing computers goes back a long way and the author provides a whistlestop tour of the highlights of this history. As the development comes to its culmination in Philadelphia, we meet the Deep Blue team, Garry Kasparov and each of the historic six games is provided in full with a detailed commentary. Chess grandmaster Yasser Seirawan provided a lively commentary throughout the match and here provides a Foreword about the significance of this event.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 340 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This book links the challenges to which the electricity network is exposed with the range of new technology, methodologies and market mechanisms known under the name 'smart grid.' The main challenges will be described by the way in which they impact the electricity network: the introduction of renewable electricity production, energy efficiency, the introduction and further opening of the electricity market, increasing demands for reliability and voltage quality, and the growing need for more transport capacity in the grid. Three fundamentally different types of solutions are distinguished in this book: solutions only involving the electricity network (like HVDC and active distribution networks), solutions including the network users but under the control of the network operator (like requirements on production units and curtailment), and fully market-driven solutions (like demand response). An overview is given of the various solutions to the challenges that are possible with new technology; this includes some that are actively discussed elsewhere and others that are somewhat forgotten. Linking the different solutions with the needs of the electricity network, in the light of the various challenges, is a recurring theme in this book. Table of Contents: Introduction / The Challenges / Solutions in the Grid / Participation of Network Users / Market Incentives / Discussion / ConclusionsSpringer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 236 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -For more than a century, oil has been the engine of growth for a society that delivers an unprecedented standard of living to many. We now take for granted that economic growth is good, necessary, and even inevitable, but also feel a sense of unease about the simultaneous growth of complexity in the processes and institutions that generate and manage that growth. As societies grow more complex through the bounty of cheap energy, they also confront problems that seem to increase in number and severity. In this era of fossil fuels, cheap energy and increasing complexity have been in a mutually-reinforcing spiral. The more energy we have and the more problems our societies confront, the more we grow complex and require still more energy. How did our demand for energy, our technological prowess, the resulting need for complex problem solving, and the end of easy oil conspire to make the Deepwater Horizon oil spill increasingly likely, if not inevitable This book explains the real causal factors leading up to the worst environmental catastrophe in U.S. history, a disaster from which it will take decades to recover.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 252 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -This volume, like the others, not only focuses upon the individual missions within the decade but also upon key challenges facing human space exploration at specific points within those years - from the problems of simply breathing and eating in space to the challenges of venturing outside in a pressurized spacesuit, the development of newer and better space toilets, and the difficulties of locomotion on the Moon. The Eighties was a time when traveling into space far more commonplace. Examining in detail the American and Soviet fronts, Ben Evans gives a comprehensive analysis of the varying fortunes of the U.S. space shuttle in the Eighties, including its early test flights and commercial flights, its problems, the 51L tragedy and its aftermath, and the resumption of operations with STS-26. The U.S. story ends with STS-37 in April 1991. In the Soviet sphere, two pivotal space station efforts - Salyut 7 and its succesor, Mir - are considered, showing how they were alike and different.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 496 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Every amateur astronomer has at least heard of the many different catalogs of deep-sky objects; the mostwell knownare the Messier, the Caldwell, the Herschel, and the NGC. All of these catalogs are, in general, readily available, but very few amateur observers are in a position to choose the best catalog for their particular deep-sky observing program, know how to use the catalog, or evenrealize just how many there are out there!The Amateur Astronomer's Guide to the Deep-sky Catalogs is a singlecompilation of the historical and modern astronomical deep-sky catalogs.It discusses their origins, compares what's in them, explains how to interpret the data they contain, and even outlines how readers can create suitable 'custom' catalogs for their own use. The last section provides a set of three deep-sky catalogs created by the author, for observers of different levels of experience, from newcomer to expert.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 392 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Cardiac tissue engineering aims at repairing damaged heart muscle and producing human cardiac tissues for application in drug toxicity studies. This book offers a comprehensive overview of the cardiac tissue engineering strategies, including presenting and discussing the various concepts in use, research directions and applications. Essential basic information on the major components in cardiac tissue engineering, namely cell sources and biomaterials, is firstly presented to the readers, followed by a detailed description of their implementation in different strategies, broadly divided to cellular and acellular ones. In cellular approaches, the biomaterials are used to increase cell retention after implantation or as scaffolds when bioengineering the cardiac patch, in vitro. In acellular approaches, the biomaterials are used as ECM replacement for damaged cardiac ECM after MI, or, in combination with growth factors, the biomaterials assume an additional function as a depot for prolonged factor activity for the effective recruitment of repairing cells. The book also presents technological innovations aimed to improve the quality of the cardiac patches, such as bioreactor applications, stimulation patterns and prevascularization.This book could be of interest not only from an educational perspective (i.e. for graduate students), but also for researchers and medical professionals, to offer them fresh views on novel and powerful treatment strategies. We hope that the reader will find a broad spectrum of ideas and possibilities described in this book both interesting and convincing.Table of Contents: Introduction / The Heart: Structure, Cardiovascular Diseases, and Regeneration / Cell Sources for Cardiac Tissue Engineering / Biomaterials: Polymers, Scaffolds, and Basic Design Criteria / Biomaterials as Vehicles for Stem Cell Delivery and Retention in the Infarct / Bioengineering of Cardiac Patches, In Vitro / Perfusion Bioreactors and Stimulation Patterns in Cardiac Tissue Engineering / Vascularization of Cardiac Patches / Acellular Biomaterials for Cardiac Repair / Biomaterial-based Controlled Delivery of Bioactive Molecules for Myocardial RegenerationSpringer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 204 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The farming of deer as an alternative to traditional livestock enterprises is now firmly established and is expanding within several countries of the European Economic Community. However, the successful farming of deer requires the adoption of appropriate management schemes to accommodate the biological requirements of these animals. Much experience has now been gained and it is essential that this information becomes readily available througout the Community. In addition, as the volume of deer farming has increased a number of health problems have become recognised which present features distinct from other domestic ruminants. Although knowledge is still incomplete it would appear that deer may react to certain pathogens in a very different way to other domestic ruminants, presenting new problems of diagnosis and control. The rapid detection of these conditions and development of appropriate control strategies will be essential for the establishment of an economically viable deer farming industry in the Community. Much of the information on the management of farmed deer and their diseases is anecdotal and fragmented and the purpose of this meeting was to accelerate the dissemination of this knowledge between scientists in the Community committed to the development of this area of agricultural industry. The meeting, financed by the Commission of the European Communities from its budget for the Coordination of Agricultural Research in the Community was held in Scotland, on the 10th to 11th December, 1987.

Taschenbuch. Condizione: Neu. Neuware -Until the early seventies, tautomeric i. e. fast and reversible rearrangement reactions accompanied by migrations of carbon-centered groups - were practi cally unknown. For a long time it was assumed that the family of tautomeric reactions was confined to proto tropic transformations only. However, the discovery in the fifties of the reversible metallotropic rearrangements showed the domain of migratory tautomerism to be substantially broader. The synthesis of the metallotropic compounds was based on the substitution of a proton in prototropic compounds by an organometallic group. This approach rarely proved fruitful when attempting to effect tautomeric rearrangements of organic and organometallic groups formed by the elements to the right of carbon in the Periodic Table. By contrast, a novel approach involving an analysis of the steric requirements inherent in the structure of the transition state of a reactive center and an examination of the stereodynamic possibilities has given rise to a target-oriented molecular design of compounds capable of rapid and reversible intramolecular migration of the type indicated. The implementation of this ap proach, which is the subject of the present book, has already led to the preparation of new tautomeric compounds in which such heavy organic migrants as acyl, aryl, sulfinyl, phosphoryl, arsinyl, and other groups migrate in molecules at a frequency 6 9 of 10 -10 S-I at ambient temperature, i. e. , at the rates comparable with protonic migrations.

Taschenbuch. Condizione: Neu. Neuware -The thirty-five chapters in this book are edited versions of papers presented at the Advanced Research Workshop, State Intervention on Behalf of Children and Youth, which took place in Maratea, Italy, February 20-24, 1989. The Workshop was attended by leading child welfare researchers from most of the Western countries. Represented were scholars and practitioners from disciplines as diverse as law, social work, neurology, economics, political science, education, psychology, and psychiatry. This variety of disciplines considerably enriched the discussions at the Workshop and is reflected in a set of interesting and, we believe, potentially useful research papers. This book is divided into four sections, each dealing with dominant themes of state intervention. The first section deals with research on organizing for state intervention and related ways of providing accountability. The second section deals with research on young persons in conflict with the law, the third with research on child abuse and the final section with research on children in care. Many of the matters addressed in these papers relate to more than one of the topical theme headings and, therefore, might well have been located in different sections of the volume. Each section is introduced by an introductory statement that provides an overview of the papers and issues addressed, and suggests an agenda of research work to be undertaken. These introductions are based largely on workshop discussions and do not necessarily represent the views of their identified authors.

Buch. Condizione: Neu. Neuware -This is awide-ranging and persuasive book written by an undisputed expert. Beginning with a broad history of the Universe, Earth, Life, and Man, it considers the origins and rise of science and technology, before moving on to discuss the present state of the world and its/our possible futures. Humans on Earth then addresses the main challenges for social and economic development in the 21st century in the context of global change. It presents a detailed but non-technical analysis of questions relating to climate change, our dependence on fossil fuels, deforestation, loss of biodiversity, desertification, and air, water, soil, and ocean pollution, as well as problems related to overpopulation, poverty, social and economic inequalities, and conflict potential. The three main, but largely mutually exclusive, discourses on human development and the environment are described and discussed. The main emphasis is on the risks and uncertainties of the short-term future ¿ the next 50 to 100 years ¿ with regard to environmental degradation and the sustainability of our growth paradigm.'. a sweeping, thoughtful view of the role of humans in shaping our modern world.'Paul Epstein, Center for Health and the Global Environment, Harvard Medical SchoolSpringer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 428 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Following the development of gray-scale imaging, real-time scanning, Doppler examination, and high-frequency sonography, endosonography is one of the latest major breakthroughs in the history of diagnostic ultrasound. Although early attempts at inserting ultrasound transducers in natural cavities of the body can be traced back more than two decades, only in the past few years has technology allowed the development and commercialization of effective, easy-to-use endosono scopic probes. Because the transducer can be placed in direct contact with or close to lesions, high frequencies (up to ~2 MHz) can be used, yielding cross-sectional images of unsurpassed resolution. The availability of specially designed intracorporeal probes for specific natural cavities that are routinely explored by conventional (optical) endoscopy or palpation has significantly expanded the diagnostic applications of sonography. Transrectal and transvaginal examinations are now performed routinely in many institutions, and virtually all sonographic equipment manufac turers have in their line of products at least one endorectal and one endovaginal transducer. Most endosonoscopic probes connect to existing scanners, and for radiology departments, the invest ment for transrectal or transvaginal scanning will usually be limited to the purchase of the specific probe. In this book, clinical applications of endosonography (excluding transesophageal echocardio graphy) are covered by European and North American experts. Current equipment and techniques of examination are described in detail to help newcomers get started in the field of endosonography. 200 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -The subject of this book is the physics of vortices. A detailed analysis of the dynamics of vortices will be presented. The important topics of vorticity and molecular spin will be dealt with, including the electromagnetic analogy and quantization in superfluids. The effect of molecular spin on the dynamics of molecular nano-confined fluids using the extended Navier-Stokes equations will also be covered ¿especially important to the theory and applicability of nanofluidics and associated devices. The nanoscale boundary layer and nanoscale vortex core are regions of intense vorticity (molecular spin). It will be shown, based on molecular kinetic theory and thermodynamics, that the macroscopic (solid body) rotation must be accompanied by internal rotation of the molecules. Electric polarization of the internal molecular rotations about the local rotation axis ¿the Barnett effect ¿ occurs. In such a spin aligned system, major changes in the physical properties of the fluid result.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 144 pp. Englisch.
