Buch. Condizione: Neu. Neuware - As the computer gradually automates human-oriented tasks in multiple environ ments, the interface between computers and the ever-wider population of human users assumes progressively increasing importance. In the office environment, for instance, clerical tasks such as document filing and retrieval, and higher-level tasks such as scheduling meetings, planning trip itineraries, and producing documents for publication, are being partially or totally automated. The range of users for office oriented software includes clerks, secretaries, and businesspersons, none of whom are predominantly computer literate. The same phenomenon is echoed in the factory production line, in the securities trading floor, in government agencies, in educa tional institutions, and even in the home. The arcane command languages of yes teryear have proven too high a barrier for smooth acceptance of computerized func tions into the workplace, no matter how useful these functions may be. Computer naive users simply do not take the time to learn intimidating and complex computer interfaces. In order to place the functionality of modem computers at the disposition of diverse user populations, a number of different approaches have been tried, many meeting with a significant measure of success, to wit: special courses to train users in the simpler command languages (such as MS-DOS), designing point-and-click menu/graphics interfaces that require much less user familiarization (illustrated most clearly in the Apple Macintosh), and interacting with the user in his or her language of choice.

Buch. Condizione: Neu. Neuware - CASE Technology presents a collection of papers pertaining to the automation of the software development process. The expectations for computer-aided software engineering (CASE) have been great, but the potential of CASE has not yet been fully realized. Now, with the availability of CASE tools and technologies, software automation is beginning to achieve success. This collection focuses on the integration of tools within a CASE environment.

Buch. Condizione: Neu. Neuware - In 1964, the Fertilization and Gamete Physiology Research Training Program (FERGAP) was established at the Marine Biological Laboratories, Woods Hole, Massachusetts. Over the course of the next 12 years, under the directorship of Dr. Charles B. Metz, FERGAP brought together, trained, and inspired a generation of students in reproductive biology from all over the world. As students of C. B. Metz and as FERGAP trainees, we would like to dedicate this collected work on comparative mammalian fertilization to our teacher and mentor, Dr. Charles B. Metz. Like a number of authors contributing to this volume, we have been struck by the significant impact that C. B. Metz and FERGAP had on the development of students of reproductive biology. Applying both the classical and molecular techniques of cell biology and immunology to problems of gamete biology, Dr. Metz emphasized a comparative and analytical approach that was reflected in his own research on fertilization in Paramecia, sea urchins, frogs, and mammals. It is hoped that this volume will serve to stimulate students to discover the myriad of fascinating research problems in gamete and reproductive biology. Bonnie S. Dunbar Michael G.

Buch. Condizione: Neu. Neuware - of progress has been made in the development of In the last twenty years a great amount new magnetic materials. Permanent magnets have progressed from the AlNiCo's (with (BH)m-8 MGOe) to the strong rare-earth magnets of SmCo 'BH)m-20 MGOe), Sm2(Co,Fe,Cu,Zrh7 s 'BH)m-30 MGOe) and the recently discovered Nd-Fe-B super-magnets with (BH)m-50 MGOe. For years the magnetic storage industry has employed Fe0 and CrO for storage media and 2 3 z permalloys and ferrites for recording heads. The recent development of thin film heads, the demand of higher density of information storage and the emergence of completely new technologies, like magneto-optics, call for entirely new types of magnetic materials. Another area in which new techniques of materials preparation have made a dramatic impact is the epitaxial growth of magnetic films. Recent work has shown that this process can be controlled on the scale of atomic monolayers permitting the growth of totally artificial structures, such as artificial superlattices with a resolution on this scale. Epitaxial growth has also permitted the stabilization of metastable phases in thin film form. These new phases often possess striking properties, such as strong perpendicular anisotropies, which may prove useful for technological applications such as recording. Research on magnetic multilayers and superlattices is increasing at an accelerating pace. Complex couplings between different magnetic layers lead to new properties not seen in bulk materials.

Buch. Condizione: Neu. Neuware - Cardiac disease is the major cause of death in dialysis patients, accounting for over one third of deaths. This book focuses on myocardial function and dysfunction in chronic uremia. It is aimed at practicing and training nephrologists, cardiologists, and internists, and at research workers in the field. We have tried to produce an up-to-date, in-depth review of the subject by inviting experts in clinical epidemiology, pathophysiology, and thera peutics to write the 18 chapters. The book is divided into three sections. The first section comprises five chapters that provide an overview of the burden of illness associated with cardiac disease in end-stage renal disease and a review of clinical epidemi ological aspects of various cardiac diseases that occur in renal patients. The second section discusses abnormalities of left ventricular contractility and mass, and the factors that predispose to both systolic and diastolic disorders. The importance of hypertension, anemia, hyperparathyroidism, hyper lipidemia, and diabetes mellitus in predisposing to these abnormalities is reviewed splendidly by researchers active in these areas. The final section concentrates on therapeutics. Data and opinion on management of congestive heart failure, cardiomyopathy, coronary artery disease, hypertension, and arrhythmias are provided. In editing this book, we have reviewed an extensive literature, but un fortunately we have become more aware that substantial gaps in our knowl edge exist. Insufficient high-quality clinical research has been undertaken xiii xiv Preface regarding the various cardiac diseases that occur in end-stage renal disease.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Herb Caen, a popular columnist for the San Francisco Chronicle, recently quoted a Voice of America press release as saying that it was reorganizing in order to 'eliminate duplication and redundancy. ' This quote both states a goal of data compression and illustrates its common need: the removal of duplication (or redundancy) can provide a more efficient representation of data and the quoted phrase is itself a candidate for such surgery. Not only can the number of words in the quote be reduced without losing informa tion, but the statement would actually be enhanced by such compression since it will no longer exemplify the wrong that the policy is supposed to correct. Here compression can streamline the phrase and minimize the em barassment while improving the English style. Compression in general is intended to provide efficient representations of data while preserving the essential information contained in the data. This book is devoted to the theory and practice of signal compression, i. e. , data compression applied to signals such as speech, audio, images, and video signals (excluding other data types such as financial data or general purpose computer data). The emphasis is on the conversion of analog waveforms into efficient digital representations and on the compression of digital information into the fewest possible bits. Both operations should yield the highest possible reconstruction fidelity subject to constraints on the bit rate and implementation complexity. 760 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Causal explanations are essential for theory building. In focusing on causal mechanisms rather than descriptive effects, the goal of this volume is to increase our theoretical understanding of the way gender operates in interaction. Theoretical analyses of gender's effects in interaction, in turn, are necessary to understand how such effects might be implicated with individual-level and social structural-level processes in the larger system of gender inequality. Despite other differences, the contributors to this book all take what might be loosely called a 'microstructural' approach to gender and interaction. All agree that individuals come to interaction with certain common, socially created beliefs, cultural meanings, experiences, and social rules. These include stereotypes about gendered activities and skills, beliefs about the status value of gender, rules for interacting in certain settings, and so on. However, as individuals apply these beliefs and rules to the specific contingent events of interaction, they combine and reshape their implications in distinctive ways that are particular to the encounter. As a result, individuals actively construct their social relations in the encounter through their interaction. The patterns of relations that develop are not completely determined or scripted in advance by the beliefs and rules of the larger society. Consequently, there is a reciprocal causal relationship between constructed patterns of interaction and larger social structural forms. The constructed patterns of social relations among a set of interactants can be thought of as micro-level social structures or, more simply, 'microstructures.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 268 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The NATO Advanced Research Workshop on Fundamental Aspects of Inert Gases in Solids, held at Bonas, France from 16-22 September 1990, was the fifth in a series of meetings that have been held in this topic area since 1979. The Consultants' Meeting in that year at Harwell on Rare Gas Behaviour in Metals and Ionic Solids was followed in 1982 by the Jiilich Inter national Symposium on Fundamental Aspects of Helium in Metals. Two smaller meetings have followed-a CECAM organised workshop on Helium Bubbles in Metals was held at Orsay, France in 1986 while in February 1989, a Topical Symposium on Noble Gases in Metals was held in Las Vegas as part of the large TMS/AIME Spring Meeting. As is well known, the dominating feature of inert gas atoms in most solids is their high heat of solution, leading in most situations to an essentially zero solubility and gas-atom precipita tion. In organising the workshop, one particular aim was to target the researchers in the field of inert-gas/solid interactions from three different areas--namely metals, tritides and nuclear fuels-in order to encourage and foster the cross-fertilisation of approaches and ideas. In these three material classes, the behaviour of inert gases in metals has probably been most studied, partly from technological considerations-the effects of helium production via (n, a) reac tions during neutron irradiation are of importance, particularly in a fusion reactor environ ment-and partly from a more fundamental viewpoint. 488 pp. Englisch.

Perspective of This Volume Charles Darwin brought the Galapagos Islands to the attention of zoologists, botanists, and geologists following the six-week visit of H. M. S. Beagle to the islands in 1835. Since then published research on the biota of the islands, partic ularly in multiauthored volumes, has focused on terrestrial plants and animals. The present volume is designed specifically to provide a summary of work on the marine invertebrate fauna. One deviation from that objective was the inclusion of a chapter on land snails, which proved to be a good choice because the phylum Mollusca is now covered more thoroughly in this volume than in any single previous scholarly work on the Galapagos. The academic bottom line with this book is to elucidate the evolutionary responses of shallow water, benthic marine invertebrates to the unique set of insular conditions that exist in the Galapagos Islands. The route taken to that objective has many paths including taxonomic revision, determining biogeo graphic affinities, and examining the ecological requirements of species. The information presented here is for some groups from the islands the first stage in a thorough process that can eventually lead to an understanding of the phylogenetic relationships of these species. 492 pp. Englisch.
