Buch. Condizione: Neu. Neuware - Although some investigators have questioned the importance and even the existence of silent myocardial ischemia, documentation presented at this two day symposium leaves little doubt about its existence and importance. It has been estimated that about 3 million of the estimated 4 million angina sufferers in the United states have frequent episodes of silent myocardial ischemia. Although it is not possible to define how many Americans die due to silent ischemia, it has been suggested that the mortality rate may exceed hundreds of thousands of victims annually. Unfortunately, there still remains a lack of definitive information as to why some ischemic events are painless. Some suggest the concept that the location and size of the myocardium at jeopardy relates to pain, that the pain threshold varies from patient to patient or that there are neurological deficits in the myocardium of some patients with silent ischemia. Abnormalities in myocardial perfusion and function can occur without pain. An interesting observation presented by several investigators has been that when a coronary artery is occluded in man, no ischemic pain is perceived for the first 30 seconds. Only after a 30 second period or so of occlusion does angina occur. An even more confusing observation is that some 30 second periods of occlusion of the same vessel in the same patient results in angina while the next occlusion can be a totally silent event.

Buch. Condizione: Neu. Neuware - Environmental permits enable regulatory agencies to control the disturbance and degradation of the environment caused by man's activities. Created by governments through legislation, the permit processes are administered by elected officials. Environmental legislation is relatively new as an independent field of the law: the laws themselves are primarily a conglomeration of older legal doctrines from other fields of law, modified and adapted for particular situations (Landau and Rheingold 1971). Like other laws, environmental laws are meant to serve and protect the rights and well-being of the public. However, like other laws, they have created confusion, a proliferation of costly paperwork, and some inequities. Numerous statutes, dealing with most aspects of pollution, exist at every level of government-so many, in fact, that they frequently conflict and overlap. These statutes establish a public policy toward polluters. They also empower the regulatory bodies that issue permits. It would be impossible to compile a list of requirements for each type of permit. Therefore, this book will acquaint the reader with the common aspects of environmental permits: their terminology, components, and application processes. This book covers the permit process from initial agencies/applicant contacts through application parts and procedures, to application approval. Special emphasis has been placed on bringing together copies of laws and lists of agencies as appendices. The appendices give the reader easy access to materials that will help clarify the permit process.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book brings together into a general setting various techniques in the study of the topological properties of spaces of continuous functions. The two major classes of function space topologies studied are the set-open topologies and the uniform topologies. Where appropriate, the analogous theorems for the two major classes of topologies are studied together, so that a comparison can be made. A chapter on cardinal functions puts characterizations of a number of topological properties of function spaces into a more general setting: some of these results are new, others are generalizations of known theorems. Excercises are included at the end of each chapter, covering other kinds of function space topologies. Thus the book should be appropriate for use in a classroom setting as well as for functional analysis and general topology. The only background needed is some basic knowledge of general topology. 136 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Several recent investigations have focused attention on spaces and manifolds which are non-compact but where the problems studied have some kind of 'control near infinity'. This monograph introduces the category of spaces that are 'boundedly controlled' over the (usually non-compact) metric space Z. It sets out to develop the algebraic and geometric tools needed to formulate and to prove boundedly controlled analogues of many of the standard results of algebraic topology and simple homotopy theory. One of the themes of the book is to show that in many cases the proof of a standard result can be easily adapted to prove the boundedly controlled analogue and to provide the details, often omitted in other treatments, of this adaptation. For this reason, the book does not require of the reader an extensive background. In the last chapter it is shown that special cases of the boundedly controlled Whitehead group are strongly related to lower K-theoretic groups, and the boundedly controlled theory is compared to Siebenmann's proper simple homotopy theory when Z = IR or IR2. 324 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume contains the proceedings of the 14th Spring School of the LITP (Laboratoire d`Informatique Théorique et de Programmation, Université Paris VI-VII, CNRS) held May 12-16, 1986 in Argelès-Village on the French Catalan coast. This meeting was organized by C. Choffrut, M. Nivat, F. Robert, P. Sallé and gathered a hundred participants. The proceedings of the last two Spring Schools have already been published in this series and deal with 'Automata on Infinite Words' (LNCS 192) and 'Combinators and Functional Programming Languages' (LNCS 242). The purpose of this yearly meeting is to present the state of the art in a specific topic which has gained considerable maturity. The field chosen this year was the theory of automata networks. Though the content of this book is essentially restricted to computer science aspects of the topic, illustrations were given at the meeting on how the model of cellular automata could be used to solve problems in statistical, fluid and solid state mechanics. Applications to biology with growth models also exist. 140 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Determinantal rings and varieties have been a central topic of commutative algebra and algebraic geometry. Their study has attracted many prominent researchers and has motivated the creation of theories which may now be considered part of general commutative ring theory. The book gives a first coherent treatment of the structure of determinantal rings. The main approach is via the theory of algebras with straightening law. This approach suggest (and is simplified by) the simultaneous treatment of the Schubert subvarieties of Grassmannian. Other methods have not been neglected, however. Principal radical systems are discussed in detail, and one section is devoted to each of invariant and representation theory. While the book is primarily a research monograph, it serves also as a reference source and the reader requires only the basics of commutative algebra together with some supplementary material found in the appendix. The text may be useful for seminars following a course in commutative ring theory since a vast number of notions, results, and techniques can be illustrated significantly by applying them to determinantal rings. 248 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Transcutaneous ultrasonography is an established procedure for diagnosis and therapy in gastroenterology. However, ultrasonic images can often be hampered by pulmonary and intestinal gas and by bony and adipose tissue. In 1956 Wild and Reid reported the first results of transrectal ultrasound of the prostate [1]. In 1976 Lutz introduced an A-mode ultrasonic probe which could be introduced via the biopsy channel of an endoscope [2]. In 1978 and 1980 Hisanaga performed echocardiography using an ultrasonic transducer attached to the tip of a flexible instrument [3, 4]. In animal studies and later on in humans Di Magno has used an echoendoscope in which a small transducer was attached at the tip of a fiberoptic endoscope [5, 6]. The purpose was to overcome the limitations of transcutaneous ultrasonography by directly approaching target lesions with a high-frequency ultrasound source via the gastroin testinallumen. SJlbsequently, the first series of endoscopic ultrasonography (EUS) examinations were reported during the European congress in Stockholm [7]. The purpose of this book is: 1. To evaluate the technique and the equipment for endoscopic ultrasonography 2. To evaluate in detail the endosonographic pattern of the normal and abnormal wall structure 3. To analyze a large consecutive series of various gastrointestinal malignancies in order to determine the usefulness and accuracy of EUS in the detection, staging, and therapy of malignant diseases 4. To compare EUS with other imaging techniques References 1. 132 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This monograph arose out of a desire to develop an approach to statistical infer ence that would be both comprehensive in its treatment of statistical principles and sufficiently powerful to be applicable to a variety of important practical problems. In the latter category, the problems of inference for stochastic processes (which arise com monly in engineering and biological applications) come to mind. Classes of estimating functions seem to be promising in this respect. The monograph examines some of the consequences of extending standard concepts of ancillarity, sufficiency and complete ness into this setting. The reader should note that the development is mathematically 'mature' in its use of Hilbert space methods but not, we believe, mathematically difficult. This is in keeping with our desire to construct a theory that is rich in statistical tools for infer ence without the difficulties found in modern developments, such as likelihood analysis of stochastic processes or higher order methods, to name but two. The fundamental notions of orthogonality and projection are accessible to a good undergraduate or beginning graduate student. We hope that the monograph will serve the purpose of enriching the methods available to statisticians of various interests. 136 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The 1st International Workshop on Conditional Term Rewriting Systems took place in Orsay (University of Paris-Sud) in July 1987, and brought together most of the researchers involved in the field. Conditional rewriting has actually known important breakthroughs during the last two years; it was the purpose of the workshop to put the results together, to present new, original contributions to the domain, and to discuss still unsolved issues. Thesecontributions are reported in the proceedings. The main questions that have been addressed are the different semantics for conditional rewriting and their classification, possible extensions to the basic formalism, and the relationship between conditional rewriting and logic programming. Also, more practical issues such as applications and implementations of conditional term rewriting systems have been addressed. Descriptions of seven actual systems allowing conditional rewriting are included. 292 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Many books already exist on computer-aided design and manufacture most of which are dedicated to describing the complexities of mathematical modelling and its application to industrial problems. In the experience of the present authors, however, if the subject is to be understood within its true, industrial context it must be taught in relation to the design process. Thus, while this book discusses both modelling and industrial applications, it also tries to provide an insight into design methodology, system selection and usage, and the social relationships that exist within design and manufacturing facilities. The teaching modules which make up the book are the distillation of material used by the authors both for undergraduate courses in CAD at BruneI University, and for seminars given to industrial users. The modules are not intended to be used in isolation, but rather to serve as an introductory survey which will enable students to grasp the broad outlines of the subject. Most aspects ofthe course presented here will need to be supported by further work and reading (see 'Further Reading'). In the authors' own courses much of the geometric and modelling work described in the text is supported by tutorial activities using the university department's commercial and research CAD/CAM systems. These include the Computervision-CADDS4X and Personal Systems. 236 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This book reflects the scientific program of the annual workshop on Graph-theoretic Concepts in Computer Science in 1987. The purpose of this conference is to be the 'missing link' between theory and application of graphs in as many branches of computer science as a conference scheduled for three days without parallel sessions can permit. So the organizers of WG '87 addressed a selected group of people with a strong interest in theory and practice. The proceedings include latest results on 'classical' graph-theoretic problems (including formal language theory applied to graphs) and how to apply those results to practical problems, e.g. data bases, layout of graph operating systems, software engineering, chemistry, and modelling with graphs. 264 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book contains the papers presented at the 2nd IPMU Conference, held in Urbino (Italy), on July 4-7, 1988. The theme of the conference, Management of Uncertainty and Approximate Reasoning, is at the heart of many knowledge-based systems and a number of approaches have been developed for representing these types of information. The proceedings of the conference provide, on one hand, the opportunity for researchers to have a comprehensive view of recent results and, on the other, bring to the attention of a broader community the potential impact of developments in this area for future generation knowledge-based systems. The main topics are the following: frameworks for knowledge-based systems: representation scheme, neural networks, parallel reasoning schemes; reasoning techniques under uncertainty: non-monotonic and default reasoning, evidence theory, fuzzy sets, possibility theory, Bayesian inference, approximate reasoning; information theoretical approaches; knowledge acquisition and automated learning. 420 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Discoveries of chaotic, unpredictable behaviour in physical deterministic systems has brought about new analytic and experimental techniques in dynamics. The modern study of the new phenomena requires the analyst to become familiar with experiments (at least with numerical ones), since chaotic solutions cannot be written down, and it requires the experimenter to master the new concepts of the theory of nonlinear dynamical systems. This book is unique in that it presents both viewpoints: the viewpoint of the analyst and of the experimenter. In the first part F. Moon outlines the new experimental techniques which have emerged from the study of chaotic vibrations. These include Poincaré sections, fractial dimensions and Lapunov exponents. In the text by W. Szemplinska-Stupnicka the relation between the new chaotic phenomena and classical perturbation techniques is explored for the first time. In the third part G. Iooss presents methods of analysis for the calculations of bifurcations in nonlinear systems based on modern geometric mathematical concepts. 204 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The search for ways to overcome tumour radioresistance is a major problem of experimental and clinical radiation oncology. The diffi culties involved in the attempts to solve this problem are a matter of common knowledge. In many a laboratory extensive studies are un derway of factors determining tumour tissue response to irradiation and of methods for exerting directional effect upon those factors. Such studies have revealed that, at least at the cellular level, a considerable number of factors manifest themselves which are respon sible for radiation effect (1] Among those are: spatial heteroge neity of tumour cell population producing radioresistant cell reser ves (hypoxic cells of solid tumours); differing radiosensitivities of cell life cycle phases; intrinsic dynamics of the processes of radi ation damage and postradiation cell recovery; induction of prolifera tive processes in response to the death of some cells within the po pulation; the stochastic nature of cell kinetics and complicated in teraction between individual cell subpopulations corresponding to di fferent tumour loci. Questions arise as to whether the researchers are now in possession of adequate means for interpreting experimental findings and clinical evidence and whether there are procedures for performing complex analysis and predicting specific tumour responses to various irradiation regimens and to combined antitumoral effects, taking into account the complexities of the phenomena under study. 140 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It is essential for the traditionally industrialised countries to innovate in manu facturing to survive in the increasingly competitive world marketplace. This challenge coupled with the increasing application of computers has led to significant changes in the techniques applied in manufacturing. This book seeks to introduce those technologies that are being applied in discrete parts manufacturing. In the technIcal press there have been many phrases and acronyms coined to describe these technologies including numerical control (NC), machining centres, computer aided manufacture (CAM), computer integrated manufacture (CIM), simulation, robotics, flexible manufacturing systems (FMS), automatic assembly, factory automation, Kanban, just in time (JIT) , manufacturing automation protocol (MAP), advanced manufacturing technology (AMT), etc. The book is intended to introduce senior undergraduates, postgraduate students and practising engineers to the principles of these individual technologies and their integration into complete, automated, programmable manufacturing facilities and systems. It is hoped that this will allow the reader to have a critical perspective of the market place and potential solutions to his own current or future problems. It is also intended to indicate how the complete manufacturing facility can be viewed as a system. The book does not address the related areas of Computer Aided Design (CAD), scheduling, production control and current speculative research at any significant level. It is impossible to do justice, in this short book, to such large subject areas which, without doubt, demand books in their own right. A book such as this is still necessarily wide-ranging and occasionally superficial. 228 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -These notes were prepared for the DMV-Seminar held in Dusseldorf, Schloss Mickeln from June 28 to July 5, 1987. They consist of two parts which can be read independently. The reader is presumed to have a basic education in differential and algebraic topology. Surgery theory is the basic tool for the investigation of differential and topological manifolds. A systematic development of the theory is a long and difficult task. The purpose of these notes is to describe simple examples and at the same time to give an introduction to some of the systematic parts of the theory. The first part is concerned with examples. They are related to representations of finite groups and group actions on spheres, and are considered as a generalisation of the spherical space form problem. The second part reviews the general setting of surgery theory and reports on the computation of the surgery abstraction groups. Both parts present material not covered in any textbook and also give an introduction to the literature and areas of research. 1. REPRESENTATION FORMS AND HOMOTOPY REPRESENTATIONS.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -By 1988 the Handbook of Vegetation Science is well on its way to completion. With 7 volumes in circulation, 3 volumes in the press, and most of the remaining volumes in preparation it appears that the total task can be completed in the early 'nineties. I am especially thankful to Professor Symoens for accepting the task of editing the volume on aquatic vegetation. The main emphasis of work in phytosociology is devoted to land plants, yet the landscape analysis remains incomplete without the consideration of rivers and lakes. Avolume on inland aquatic vegetation must therefore be most helpful to the land vegetation analyst and not only to the specialist on aquatic vegetation. Professor Symoens succeeded in drafting the most competent team for his task. I am sure that all colleagues working in vegetation analysis will be grateful to them that they have taken the time and energy to complete their chapters. Handbook articles are not easy to write and certainly not easy to edit. in the landscape are treated. The The major aquatic components vegetation analysts will welcome the fact that certain physiological and ecological processes of water plants are covered for which otherwise they would have to consult the limnological literature. This volume, together with the forthcoming volume on wetlands, should completely cover the inland aquatic vegetation problematic. 400 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This series of multiple choice questions is based on the textbook Common Eye Diseases And Their Management (1985), also from Springer-Verlag. The questions have been grouped to fit in with the chapter headings in the latter. Many of the questions are supported by expanded answers but further information should be sought in the textbook. The format of the questions has been arranged so that the number of true or false answers varies and we have taken pains to eliminate the ambiguities which tend to creep into multiple choice question papers. In compiling these questions, we have attempted to incorporate a number of key facts and it will be seen that these have occasionally been repeated for emphasis. A surprisingly large amount of information is contained in questions and answers, and simply reading through both can be a useful learning experience in itself. The questions have been aimed at the medical student level but it is hoped that they may be of some value to general practitioners outside ophthalmology and perhaps also to postgraduates. The computerised Kuder-Richardson reliability index, which measures the consistency of a student's perform ance, has shown these questions to be reliable in assessing a students' knowledge. A sample of these questions has been tested in another medical school and we understand that students' marks there equate well with the results from essay questions. 120 pp. Englisch.
