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 - 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 - 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 - 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.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Vitamin C, or ascorbic acid, has a long and multifaceted scientific history. In 1937, the Nobel Prize for Physiology and Medicine was awarded to Albert Szent-Gyorgyi'in recognition of his discoveries concerning the biological oxida tion processes with special reference to vitamin C', and the Nobel Prize for Chemistry was shared by Sir Norman W. Haworth, who was the first to synthesize the vitamin. Vitamin C is a potent antioxidant, and this action represented the theoretical basis for various lines of investigation on this molecule in which the potential role of ascorbic acid in the prevention and treatment of a series of dis eases, whose pathogenesis is linked to an excess of free radicals such as athero sclerosis and cancer, have been examined. These data have been analyzed in detail by experts in biochemistry, epidemi ology, and preventive and clinical medicine in the International Symposium Vitamin C, the state of the art in disease prevention sixty years after the Nobel Prize, held in Monte Carlo from October 31 to November 1, 1997, under the aus pices and the scientific endorsement of the Nutrition Foundation of Italy and with the financial support of Bracco SpA and Merck. 144 pp. Englisch.
