Buch. Condición: Neu. Neuware - The explosion of new information on Helicobacter pylori-related disease, both in the basic sciences and in clinical medicine, has continued to progress at an unprecedented pace. In many instances H. pylori infection, both in man and in the laboratory animal, has become a model to investigate fundamental biological issues such as micro-organism host interactions, intracellular signaling, development of mucosal atrophy, mechanism of microbial resistance, disease modifying factors etc. In view of this bewildering flood of new information, another meeting on H. pylori in the successful series `Basic mechanisms to clinical cure' was organized in January 1998 in San Diego, California, to define the `state-of-affairs' in H. pylori research at this time. The main objective was to integrate this new information in a series of top-quality presentations and discussions between investigators and clinicians addressing all aspects of H. pylori research and to review the current position and future research directions. The format included state-of-the-art presentations by world experts heavily involved in H. pylori research followed by in-depth discussion on intriguing or controversial issues. The presentations were grouped according to the leading theme: characteristics of the organism, mode of transmission, mechanisms of H. pylori-induced inflammation, causation of disturbances of gastric secretory and motor function, aspects of clinical presentation and management, problems related to H. pylori-associated gastric adenocarcinoma and MALT-lymphoma, novel aspects of antimicrobial therapy and vaccination. The meeting concluded with a synoptic agenda of suggested future studies for the microbiologist, the histopathologist and the clinician. The chapters published in these proceedings accurately reflect the content of the superb presentations. The reader will readily appreciate the excellent level of the `cutting-edge' research which was described and discussed. These proceedings are another testimony to the enormous impact on basic science and clinical medicine of the H. pylori discovery. Although much was achieved, it is also readily apparent that many questions remain to be answered and many problems remain to be solved.

Buch. Condición: Neu. Neuware - Although the true economic impact of genetic modifications is yet to be realized, the potential of this new technology to benefit the food processing industry and to improve food quality is enormous. Specific genetically modified whole foods and food ingredients that have recently become available or are about to become available are described and discussed in relation to their technical performance and consumer acceptance. The regulatory, ethical and communication issues in food biotechnology are also reviewed. As the products of gene technology come on stream, decisions need to be made as to whether or not to use them. Yet, many food industry professionals have little or no background in biotechnology and have a limited concept of possible applications in foods. Therefore, this book aims to foster a greater understanding of the benefits and potential pitfalls of this new technology.

Buch. Condición: Neu. Neuware - When we ask whether something exists, we expect a yes or no answer, not a further query about what kind of existence, how much of it, whether we mean existence for you or existence for me, or whether we are asking about some property which it might have. In this book, this simple requirement is defended and pursued into its various and sometimes surprising implications. In the course of this pursuit, such questions arise as `Do appearances exist ' `Do unknowable things exist ' `Do past and future exist ' `Does God necessarily exist ' This novel and non-technical approach to important philosophical questions will be of interest to senior students of philosophy and, indeed, to all general readers with philosophical interests.

Buch. Condición: Neu. Neuware - In recent years, the study of events and their role as implicit arguments of predicates has been at the center of much important work in semantics and the syntax/semantics interface. This volume brings together fourteen original studies by leading scholars in semantics and the syntax/semantics interface, covering a broad spectrum of research into the role of events in grammar. The papers extensively address the following topics, among others: event arguments and thematic argument structure; the role of events in verbal aspectual distinctions; events and the distinction between stage and individual level predicates; the role of events in the analysis of plurality and scope relations, the mass/count distinction, and propositional attitudes.

Buch. Condición: Neu. Neuware - Primary sclerosing cholangitis is a chronic disease of the intra- and extrahepatic bile ducts leading to obstructions and dilatations followed by liver cirrhosis and in some cases cholangiocarcinoma. In 50% of cases primary sclerosing cholangitis is associated with inflammatory bowel disease. The cause of the disease is unknown and many questions concerning the pathogenesis still remain open. In recent years our knowledge of the natural course, the risk of cholangiocarcinoma and the possibility of medical, endoscopic and surgical treatment has increased. Ursodeoxycholic acid, endoscopic treatment and liver transplantation have become standard therapeutic procedures. This book is the proceedings of the Falk Workshop held on October 3, 1997, in Freiburg, Germany (Part II of the Liver Week Freiburg 1997), and covers the most important aspects of this fascinating disease.

Buch. Condición: Neu. Neuware - Supervisory Control of Discrete Event Systems Using Petri Nets presents a novel approach to its subject. The concepts of supervisory control and discrete event systems are explained, and the background material on general Petri net theory necessary for using the book's control techniques is provided. A large number of examples is used to illustrate the concepts and techniques presented in the text, and there are plenty of references for those interested in additional study or more information on a particular topic. Supervisory Control of Discrete Event Systems Using Petri Nets is intended for graduate students, advanced undergraduates, and practicing engineers who are interested in the control problems of manufacturing, communication and computer networks, chemical process plants, and other high-level control applications. The text is written from an engineering perspective, but it is also appropriate for students of computer science, applied mathematics, or economics. The book contains enough background material to stand alone as an introduction to supervisory control with Petri nets, but it may also be used as a supplemental text in a course on discrete event systems or intelligent autonomous control.

Neuware - Iterative Learning Control (ILC) differs from most existing control methods in the sense that, it exploits every possibility to incorporate past control informa tion, such as tracking errors and control input signals, into the construction of the present control action. There are two phases in Iterative Learning Control: first the long term memory components are used to store past control infor mation, then the stored control information is fused in a certain manner so as to ensure that the system meets control specifications such as convergence, robustness, etc. It is worth pointing out that, those control specifications may not be easily satisfied by other control methods as they require more prior knowledge of the process in the stage of the controller design. ILC requires much less information of the system variations to yield the desired dynamic be haviors. Due to its simplicity and effectiveness, ILC has received considerable attention and applications in many areas for the past one and half decades. Most contributions have been focused on developing new ILC algorithms with property analysis. Since 1992, the research in ILC has progressed by leaps and bounds. On one hand, substantial work has been conducted and reported in the core area of developing and analyzing new ILC algorithms. On the other hand, researchers have realized that integration of ILC with other control techniques may give rise to better controllers that exhibit desired performance which is impossible by any individual approach.

Buch. Condición: Neu. Neuware - Information systems are the backbone of many of today's computerized applications. Distributed databases and the infrastructure needed to support them have been well studied. However, this book is the first to address distributed database interoperability by examining the successes and failures, various approaches, infrastructures, and trends of the field. A gap exists in the way that these systems have been investigated by real practitioners. This gap is more pronounced than usual, partly because of the way businesses operate, the systems they have, and the difficulties created by systems' autonomy and heterogeneity. Telecommunications firms, for example, must deal with an increased demand for automation while at the same time continuing to function at their current level. While academics are focusing on investigating differences between distributed databases, federated databases, heterogeneous databases, and, more generally, among loosely connected and tightly coupled systems, those who have to deal with real problems right away know that the only relevant research is the one that will ensure that their system works to produce reasonably correct results. Interconnecting Heterogeneous Information Systems covers the underlying principles and infrastructures needed to realize truly global information systems. The book discusses technologies related to middleware, the Web, workflows, transactions, and data warehousing. It also overviews architectures with a discussion of critical issues. The book gives an overview of systems that can be viewed as learning platforms. While these systems do not translate to successful commercial realities, they push the envelope in terms of research. Successful commercial systems have benefited from the experiments conducted in these prototypes. The book includes two case studies based on the authors' own work. Interconnecting Heterogeneous Information Systems issuitable as a textbook for a graduate-level course on Interconnecting Heterogeneous Information Systems, as well as a secondary text for a graduate-level course on database or information systems, and as a reference for researchers and practitioners in industry.

Buch. Condición: Neu. Neuware - Database Recovery presents an in-depth discussion on all aspects of database recovery. Firstly, it introduces the topic informally to set the intuitive understanding, and then presents a formal treatment of recovery mechanism. In the past, recovery has been treated merely as a mechanism which is implemented on an ad-hoc basis. This book elevates the recovery from a mechanism to a concept, and presents its essential properties. A book on recovery is incomplete if it does not present how recovery is practiced in commercial systems. This book, therefore, presents a detailed description of recovery mechanisms as implemented on Informix, OpenIngres, Oracle, and Sybase commercial database systems. Database Recovery is suitable as a textbook for a graduate-level course on database recovery, as a secondary text for a graduate-level course on database systems, and as a reference for researchers and practitioners in industry.

Buch. Condición: Neu. Neuware - The present decade is opening new frontiers in high-energy astrophysics. After the X-ray satellites in the 1980's, including Einstein, Tenma, EXOSAT and Ginga, several satellites are, or will soon be, simultaneously in orbit offering spectacular advances in X-ray imaging at low energies (ROSATj Yohkoh) as well as at high energies (GRANAT), in spectroscopy with increased bandwidth (ASCAj SAX), and in timing (XTE). While these satellites allow us to study atomic radiation from hot plasmas or energetic electrons, other satellites study nuclear radiation at gamma-ray energies (CGRO) associated with radioactivity or spallation reactions. These experiments show that the whole universe is emitting radiation at high energies, hence we call it the 'hot universe. ' The hot universe, preferentially emitting X- and gamma-rays, provides us with many surprises and much information. A symposium 'The Hot Universe' was held in conjunction with the XXIIIrd General Assembly of the International Astronomical Union, at Kyoto on August 26-30 in 1997. The proceedings are organized as follows. Synthetic view of 'the hot universe' is discussed in Section 1, 'Plasma and Fresh Nucleosynthesis Phenomena'. Timely discussions on the strategy for future missions 'Future Space Program' are found in Section 2. Then the contents are divided into two major subjects: the compact objects and thin hot diffuse plasmas. Section 3 is devoted to the category of compact objects which includes white dwarfs, neutron stars, and gravitationally collapsed objects: stellar mass black holes or active galactic nuclei.

Buch. Condición: Neu. Neuware - Animal cell technology is becoming an increasingly important part of biotechnology and many products are now used in human health care and for veterinary applications. However, there are many times more products actually in the developmental pipelines of the biotechnology industry, including various phases of clinical trials. The Proceedings of the 15th Meeting of the European Society for Animal Cell Technology (Tours, France, September 1997) presents the actual current state as well as New Developments and Applications in Animal Cell Technology for the benefit of society. These Proceedings represent both the current state and applications of animal cell technology and the way the technology is expanding into new areas to give a unique insight into new products and applications for human and animal health care.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -An in-depth account of graph theory, written for serious students of mathematics and computer science. It reflects the current state of the subject and emphasises connections with other branches of pure mathematics. Recognising that graph theory is one of several courses competing for the attention of a student, the book contains extensive descriptive passages designed to convey the flavour of the subject and to arouse interest. In addition to a modern treatment of the classical areas of graph theory, the book presents a detailed account of newer topics, including Szemeredi's Regularity Lemma and its use, Shelah's extension of the Hales-Jewett Theorem, the precise nature of the phase transition in a random graph process, the connection between electrical networks and random walks on graphs, and the Tutte polynomial and its cousins in knot theory. Moreover, the book contains over 600 well thought-out exercises: although some are straightforward, most are substa ntial, and some will stretch even the most able reader. 412 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Over the past two decades in the West there has been a substantial re-appraisal of the Stalinist period. Social historians, in particular, have focused their attention on the social dynamics of Stalinism. This collection of essays is based on a conference held at the School of Slavonic & East European Studies, the University of London, on 'Stalin and Stalinism'. The contributors have analysed specific areas of the research available on Stalin and Stalinism in the USSR debate. Their work should be placed within the context of current scholarship in the field, both in the Former Soviet Union and the West. This groundbreaking text will be critical in stimulating interest in the subject and providing material for further debate. 220 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The fall of the Communist regime in the USSR and Russia's search for a democratic and prosperous market-based future is one of the most compelling episodes of the end of the twentieth century. A central part in this drama is being played by political elites. These essays, written by some of the leading scholars in the field, analyse various aspects of the role being played by elites and leaders in Russian politics. Among the issues dealt with are: the origins of the Russian elites, including the issue of continuity with the Soviet past; the relationship between political and economic elites; the means taken by elites to structure politics and their relations; the dynamic of elite politics, and the nature of post-communism. These essays deal with many of the crucial questions facing Russia today. 190 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Mik16s Cs6rgO and David M. Mason initiated their collaboration on the topics of this book while attending the CBMS-NSF Regional Confer ence at Texas A & M University in 1981. Independently of them, Sandor Cs6rgO and Lajos Horv~th have begun their work on this subject at Szeged University. The idea of writing a monograph together was born when the four of us met in the Conference on Limit Theorems in Probability and Statistics, Veszpr~m 1982. This collaboration resulted in No. 2 of Technical Report Series of the Laboratory for Research in Statistics and Probability of Carleton University and University of Ottawa, 1983. Afterwards David M. Mason has decided to withdraw from this project. The authors wish to thank him for his contributions. In particular, he has called our attention to the reverse martingale property of the empirical process together with the associated Birnbaum-Marshall inequality (cf.,the proofs of Lemmas 2.4 and 3.2) and to the Hardy inequality (cf. the proof of part (iv) of Theorem 4.1). These and several other related remarks helped us push down the 2 moment condition to EX 00 in all our weak approximation theorems. 184 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The idea for this book grew out of proposals at the APL86 con ference in Manchester which led to the initiation of the I-APL (International APL) project, and through it to the availability of an interpreter which would bring the advantages of APL within the means of vast numbers of school children and their teachers. The motivation is that once school teachers have glimpsed the possibilities, there will be a place for an 'ideas' book of short programs which will enable useful algorithms to be brought rapidly into classroom use, and perhaps even to be written and developed in front of the class. A scan of the contents will show how the conciseness of APL makes it possible to address a huge range of topics in a small number of pages. There is naturally a degree of idiosyncrasy in the choice of topics - the selection I have made reflects algo rithms which have either proved useful in real work, or which have caught my imagination as candidates for demonstrating the value of APL as a mathematical notation. Where appropriate, notes on the programs are intended to show the naturalness with which APL deals with the mathematics concerned, and to estab lish that APL is not, as is often supposed, an unreadable lan guage written in a bizarre character set. 200 pp. Englisch.

Buch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -My initial purpose in writing this book was to offer readers an update of my book Fetal Alcohol Syndrome and Fetal Alcohol Effects (Plenum, 1984), which con tained a broad overview of the history (actually the absence of any history) ofthe awareness of alcohol's teratogenic potential; a review of alcohol's pharmacology, especially with respect to pregnancy; a survey of the physical and behavioral effects of prenatal alcohol exposure; and an overview of the mechanisms sus pected of being responsible for those effects. I have omitted most of the previously examined historical and pharmacologi cal information because not much of what was previously discussed needed revision. On the other hand, because much more has been learned about the consequences of prenatal alcohol exposure and its potential mechanisms of action, I have considerably expanded my discussion of these topics. In doing so, I have attempted to include as much new material as possible without (I hope) being overly pedantic and thereby losing the proverbial forest for the trees. No book is ever entirely neutral in the topics it discusses, the issues it raises, or in its conclusions. In sifting through hundreds and oftentimes thousands of articles, writers have to choose which facts to emphasize and which to ignore. Every idea cannot be chronicled and every article cannot (and should not) be cited. In going about the business of picking and choosing, however, a writer has an obligation to present the arguments for and against a particular conclusion. 276 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Expression of Attitude deals with a number of broad but interrelated questions: what are attitudes, how do they relate to behavior, how are they acquired, and in what ways can they be shared The author argues that consistency, within attitude structure and between attitudes and behavior, arises primarily from interpersonal rather than intrapersonal processes. Emphasis is placed on how people interpret behavior as an expression of attitude, and what they demand of such behavior before they treat it as decodable in a particular way. 96 pp. Englisch.
