Buch. Condizione: Neu. Neuware - The present century has been a disappointing one for comets, but past centuries often featured spectacular, unforgettable comet shows that dominated the night (and even daytime) sky for months: comets that outshone Venus or even the Moon, whose spectacular tails stretched more than halfway across the sky or were weirdly split, and whose apparition was held responsible for everything from wars to unusually good wine vintages. Published to coincide with the first naked-eye appearance of Comet Hale-Bopp, perhaps our own comet of the century, this book is an irresistible guide to comet facts and lore throughout history.

Buch. Condizione: Neu. Neuware - Biodegradation is the dominant pathway for the environmental transformation of most chemicals and information on a chemical's biodegradability is essential for proper risk assessment. But there are few methods for predicting whether or not a chemical is biodegradable, since this depends on the chemical's structure as well as on the environmental conditions that it encounters. The present book deals with quantitative structure-biodegradability relationship models (QSBRs), emphasizing the biological and ecological part of the biodegradation process. Surveys are given of the microbial aspects of biodegradation and the methods available for testing biodegradability. New trends and methods in biodegradation modelling are reviewed, including contributions on computerized biodegradability prediction systems. Some of the newly developed models for assessing risk and ecological impact in aquatic and terrestrial environments have been validated, and this process is discussed. Audience: Scientists active in microbiology, the environmental sciences, biotechnology and bioremediation. Policy makers will find the book indispensable in assessing the present state of the art on the biodegradability of substances.…

Buch. Condizione: Neu. Neuware - Although its concern is jurisprudence, The Tapestry of the Law is intended to offer neither an original theory of or about law nor an account of other people's theories in textbook form. It is, rather, an attempt to approach the subject without following either of these conventions. The reasons are as follows. Those engaged in legal theory are prone to assert that one cannot properly understand the law unless one takes a jurisprudential approach - preferably their own - to it. Equally, those engaged in exposition of the law may counter that legal theory fails to pay adequate attention to actual law. There is at least some truth in these claims. Analyses, courses and textbooks on both sides do often seem to be produced without reference to the other. Yet such isolation is probably more apparent than real. Most, if not all, so-called 'black letter' lawyers do operate on the basis of certain jurisprudential understandings, even if these are not articulated ones. In the frequently quoted words ofF C S Northrop: There are lawyers, judges and even law professors who tell us they have no legal philosophy.…

Buch. Condizione: Neu. Neuware - International concern in scientific, industrial, and governmental communi ties over traces of xenobiotics in foods and in both abiotic and biotic envi ronments has justified the present triumvirate of specialized publications in and this field: comprehensive reviews, rapidly published research papers progress reports, and archival documentations. These three international publications are integrated and scheduled to provide the coherency essential for nonduplicative and current progress in a field as dynamic and complex as environmental contamination and toxicology. This series is reserved ex clusively for the diversified literature on 'toxic' chemicals in our food, our feeds, our homes, recreational and working surroundings, our domestic animals, our wildlife and ourselves. Tremendous efforts worldwide have been mobilized to evaluate the nature, presence, magnitude, fate, and toxi cology of the chemicals loosed upon the earth. Among the sequelae of this broad new emphasis is an undeniable need for an articulated set of authoritative publications, where one can find the latest important world literature produced by these emerging areas of science together with docu mentation of pertinent ancillary legislation. Research directors and legislative or administrative advisers do not have the time to scan the escalating number of technical publications that may contain articles important to current responsibility. Rather, these individu als need the background provided by detailed reviews and the assurance that the latest information is made available to them, all with minimal literature searching. …

Buch. Condizione: Neu. Neuware - Climate and Environmental Database Systems contains the papers presented at the Second International Workshop on Climate and Environmental Database Systems, held November 21-23, 1995, in Hamburg, Germany. Climate and environmental data may be separated into two classes, large amounts of well structured data and smaller amounts of less structured data. The large amounts are produced by numerical climate models and by satellites, handling data in the order of magnitude of 100 Tbytes for the climate modelling sites and 1000 Tbytes for the recording and processing of satellite data. Smaller amounts of poorly structured data are the environmental data, which come mainly from observations and measurements. Present-day problems in data management are connected with a variety of data types. Climate and Environmental Database Systems addresses the state of the art, practical experience, and future perspectives for climate and environmental database systems, and may be used as a text for a graduate level course on the subject or as a reference for researchers or practitioners in industry.…

Buch. Condizione: Neu. Neuware - This volume contains the proceedings of the Workshop Energy Methods for Free Boundary Problems in Continuum Mechanics, held in Oviedo, Spain, from March 21 to March 23, 1994. It is well known that the conservation laws and the constitutive equations of Continuum Mechanics lead to complicated coupled systems of partial differential equations to which, as a rule, one fails to apply the techniques usually employed in the studies of scalar uncoupled equations such as, for instance, the maximum principle. The study of the qualitative behaviour of solutions of the systems re quires different techniques, among others, the so called, Energy Methods where the properties of some integral of a nonnegative function of one or several unknowns allow one to arrive at important conclusions on the envolved unknowns. This vol ume presents the state of the art in such a technique. A special attention is paid to the class of Free Boundary Problems. The organizers are pleased to thank the European Science Foundation (Pro gram on Mathematical treatment of free boundary problems), the DGICYT (Spain), the FICYT (Principado de Asturias, Spain) and the Universities of Oviedo and Complutense de Madrid for their generous financial support. Finally, we wish to thank Kluwer Academic Publishers for the facilities received for the publication of these Proceedings.…

Buch. Condizione: Neu. Neuware - Recent advances in our understanding of the fundamental role of bioactive lipids in normal and abnormal physiology was the theme of the XVlth International Spring Sympo 6-9, 1996 at the George Washington University School sium on Health Sciences held on May of Medicine in Washington, D.C. Over 250 participants shared their latest findings on fundamental mechanisms in lipid metabolism, transport, and signal transduction. Most of the papers presented at the plenary sessions have been collected in this volume, which is divided into seven parts. The focus of Part I is on the new roles that fatty acids and esters play in cellular function. These activities include regulation of gene expression, control of eicosanoid-me diated responses, and intracellular calcium sequestration. Most biological effects of fatty acids, esters, and phospholipids are transmitted via the interaction of these lipid molecules with specific lipid binding proteins. The chapters in Part II detail the involvement of these in the transport of fatty acids, fatty acyl CoA esters, and phospholipids, and in the proteins modulation of the fatty acid-induced activation of the peroxisome proliferator-activated receptors. The study of arachidonic acid metabolism continues to be the subject of intense interest and research. A number of studies in Part III deal with the substantial differences between the constitutive prostaglandin H synthase isozyme (PGHS-l or COX-I) and the inducible form PGHS-2 (COX-2) regarding compartmentation, control, and expression.…

The prominent issues which are addressed in this book concern the direction of time, the reality of tenses, the objectivity of becoming, the existence in time, and the logical structures of reasoning about time. The papers have been written based on different approaches, partly depending on whether the authors subscribe to an A-theory or a B-theory of time. Audience: Due to the broad variety of approaches the book contains important contributions both for philosophers, philosophers of science, logicians and for scientists working in the field of language and AI.…

Buch. Condizione: Neu. Neuware - Trade in temperate zone farm products between the developed countries has been beset with problems since the GATT's inception in 1947. The basic problem was always that the conditions in world agricultural markets were distorted by the national agricultural policies followed by all developed countries - policies which national authorities were reluctant to adapt to conform with the requirements of a liberal international trading system for agricultural products. This book describes and analyses the attempts that were made to make trade in agriculture less distorted, more stable and predictable, and less of a dangerous source of political friction between nations, in successive rounds of negotiations under the General Agreement on Tariffs and Trade in the 45-year period from GATT's inception in 1947 to the end of the Uruguay Round in 1993. While the book analyses the development of international trade policy throughout the post-war period, particular attention is given to the Kennedy, Tokyo and Uruguay Rounds of GATT negotiations in which the problems of trade in agricultural products were confronted.…

Buch. Condizione: Neu. Neuware - The theory of blood circulation is the oldest and most advanced branch of biomechanics, with roots extending back to Huangti and Aristotle, and with contributions from Galileo, Santori, Descartes, Borelli, Harvey, Euler, Hales, Poiseuille, Helmholtz, and many others. It represents a major part of humanity's concept of itself. This book presents selected topics of this great body of ideas from a historical perspective, binding important experiments together with mathematical threads. The objectives and scope of this book remain the same as in the first edition: to present a treatment of circulatory biomechanics from the stand points of engineering, physiology, and medical science, and to develop the subject through a sequence of problems and examples. The name is changed from Biodynamics: Circulation to Biomechanics: Circulation to unify the book with its sister volumes, Biomechanics: Mechanical Properties of Living Tissues, and Biomechanics: Motion, Flow, Stress, and Growth. The major changes made in the new edition are the following: When the first edition went to press in 1984, the question of residual stress in the heart was raised for the first time, and the lung was the only organ analyzed on the basis of solid morphologic data and constitutive equations. The detailed analysis of blood flow in the lung had been done, but the physiological validation experiments had not yet been completed. …

Buch. Condizione: Neu. Neuware - Since the first edition of this book was published in 1987, there have been several important changes in the state of numerical field computation, as discussed in the Introduction. These changes have motivated the publication of this second edition. As with the first edition, the objective of this second edition is to give the newcomer to field computation the information needed to perform practical field computations. Again, clarity of presentation is given greater emphasis than a high degree of sophistication or the state of the art. And again, the basic concepts of field computation are presented as well as the commonly used algorithms. Several persons have provided much valuable information for this second edition. I wish to thank Professor Giorgio Molinari of the University of Genoa, Italy for advice regarding adaptive mesh generation; Dr. C. R. E. Emson of Vector Fields, Ltd., England and Dr. John Brauer of McNeal-Schwendler Corp. for their advice on transient eddy current computation; and Dr. Zoltan Cendes of Ansoft Corp. for information about their adaptive mesh generator. Again, I would like to acknowledge the support for this second edition by my wife, Candace. Again, I could not have written this book without her support.…

Buch. Condizione: Neu. Neuware - This book addresses the behavior of inorganic material in combustion systems. The past decade has seen unprecedented improvements in understanding the rates and mecha nisms of inorganic transformations and in developing analytical tools to predict them. These tools range from improved fuel analysis procedures to predictive computer codes. While this progress has been met with great enthusiasm within the research community, the practices of the industrial community remain largely unchanged. The papers in this book were selected from those presented at an Engineering Foundation Conference of the same title. All have been peer reviewed. The intent of the conference was to illustrate the application of advanced technology to ash-related problems in boilers and, by so doing, engage the research and industrial communities in more productive dialog. Those attending the conference generally felt that we were successful on these counts. We also engaged the industrial community to a greater extent than ever before in the conference discussion and presentation. We hope these proceedings will facilitate a continued and improved interaction between industrial and research communities. Behavior of inorganic material has long been recognized as one of the major considerations affecting the design and operation of boilers that burn ash-producing fuels. The practical problems associated with the behavior are sometimes catastrophic and spec tacular, ranging from major slag falls that damage the bottom of furnaces to complete plugging of convection passes.…

Buch. Condizione: Neu. Neuware - The preceding volume appeared in 1987 and covered the literature up to the end of 1984. The present work extends the coverage to the end of 1994 with a sprinkling of references to 1995 papers. Nearly 900 new qui nones are described, including one or two which were overlooked previously, together with new work on older compounds. For each new quinone information is provided on the distribution, spectra, structure and chemistry, and on biosynthesis where available. Sadly, there is very little new chemistry, as structures are now elucidated almost entirely by spectroscopic methods and X-ray analysis. As always I am grateful to many colleagues who sent me papers and other information in advance of publication. 1972 and 1987 volumes are referred to as NOQ II and NOQ III, The respectively. In the spectroscopic data the notation ( ) indicates that informa tion is missing or is dubious. R.H.T. Aberdeen, November 1995 1 Benzoquinones 1 New sources of p-benzoquinone are the cephalic glands of Eucera bees and 2 Arthrobacter bacteria and it is part ofthe defensive secretion ofthe caterpillar 3 Romalea guttata.
