Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The attack of atrial fibrillation experienced by President Bush of the United States attracted more attention from the general public to atrial fibrillation than ever before. Also, there is a growing body of knowledge of the pathophysiologic mechanism, the pathology and epidemiology, and especially of the thrombo-embolic complications of this arrhythmia, which is responsible for a renewed interest of the clinician in this very common human arrhythmia. These new perspectives on atrial fibrillation were presented during a conference on `Atrial Fibrillation, a Treatable Disease ', organized on May 7, 1992, in Amsterdam, the Netherlands. Atrial fibrillation is not the prerogative of the cardiologist only. Many practitioners from other areas in health care, in particular general physicians, internists and neurologists, are faced with this arrhythmia and its untoward consequences. This book bridges the gap between theory, experiment and the clinic. Emphasis is therefore on the selection of the optimal approach, including pharmacotherapy, catheter ablation, pacemaker and surgical therapy, based on the current scientific insights in the mechanism and prevention of atrial fibrillation. 328 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Time and Transcendence provides a new theory of secularization in the Catholic context, a new interpretation of the origins of modern historical science, and a new reading of Heidegger's theories of time and history. The author shows how a secular sense of the past evolved in early modern French memoirs. Memoirs uncovered a level of personal experience that was then applied as an intuitive framework for the study of history. Modern history's scientific study of sources is embedded in the imaginative sense of a personal past. Nineteenth-century French Traditionalists countered this threat of a secular past by expanding the concept of tradition to include all of history. Neoscholasticism then canonized philosophy as Catholic tradition, turning the history of philosophy against secular culture. Heidegger's thinking developed in the contexts of both this Catholic counterattack and the fin-de-siècle disillusion with secular history. Against fin-de-siècle notions of memory as a better way of penetrating the past, Heidegger recast history as future-oriented action. Rejecting both secular culture and religious tradition, he used history as a tool for secularizing religious experiences that secular culture had ignored, such as grace, mystical experience, and death. This book shows that while religion can turn a self-conscious secular culture against itself, ultimately the religious critique of secular culture can also be turned against religion. 328 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Many problems in celestial mechanics, physics and engineering involve the study of oscillating systems governed by nonlinear ordinary differential equations or partial differential equations. This volume represents an important contribution to the available methods of solution for such systems. The contents are divided into six chapters. Chapter 1 presents a study of periodic solutions for nonlinear systems of evolution equations including differential equations with lag, systems of neutral type, various classes of nonlinear systems of integro-differential equations, etc. A numerical-analytic method for the investigation of periodic solutions of these evolution equations is presented. In Chapters 2 and 3, problems concerning the existence of periodic and quasiperiodic solutions for systems with lag are examined. For a nonlinear system with quasiperiodic coefficients and lag, the conditions under which quasiperiodic solutions exist are established. Chapter 4 is devoted to the study of invariant toroidal manifolds for various classes of systems of differential equations with quasiperiodic coefficients. Chapter 5 examines the problem concerning the reducibility of a linear system of difference equations with quasiperiodic coefficients to a linear system of difference equations with constant coefficients. Chapter 6 contains an investigation of invariant toroidal sets for systems of difference equations with quasiperiodic coefficients. For mathematicians whose work involves the study of oscillating systems. 300 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The coordination of regulations in Europe is a process characterised by a huge amount of information in different forms (decisions, regulations, directives, recommendations and opinions), at various stages of consideration. While current developments are debated in the influential media, no coherent overview is offered of the European Community coordination efforts as a whole, nor of relationships with other international regulations produced, for example, in the framework of the Bank for International Settlements (BIS). Such an overview is essential in order to gain a proper understanding of the consequences for the various countries. Financial Integration in Europe, with a Foreword by Professor Ingo Walter of New York University and INSEAD, provides an overview of the core of European and BIS regulations insofar as these have been published in the Official Journal of the European Communities (OJEC) and in official BIS documents up to April 1, 1992. This publication covers the liberalisation of capital movements in Europe and coordination efforts on credit institutions, investment firms, the securities market, undertakings for collective investment in transferable securities, insurance companies, and pension funds. 220 pp. Englisch.…

As a stereotype she has been 'fabricated', that is to say constructed as a 'figure in the carpet' of the fin-de-siècle. The book argues that Rider Haggard's She-Who-Must-Be-Obeyed , Bram Stoker's female vampires and Conrad's destructive Malayan or African women, even Hardy's Tess , are all caught up in a series of late nineteenth-century contexts: biological determinism, imperialism, race, theories about female sexuality, degeneration and evolutionary theory. 257 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book provides an overview of the underlying physics and technology of modern waveguide optoelectronics. By presenting these two aspects together in a coherent manner, readers will gain an appreciation of the fundamental physical limits to device performance as well as a critical understanding of the state of the art. Starting from the fundamental optical properties of matter, the book moves on to describe methods of device design, with an emphasis on low dimensional systems. The potential of III-IV semiconductors is highlighted because of their ability to incorporate lasers, waveguides, modulaters and detectors. However, other technologies -- principally lithium niobate and fibre devices -- are studied and contrasted. The role of nonlinear optics and femtosecond pulses within the framework of waveguide optics is evaluated. Optical fibre devices show considerable promise in a range of system applications and such devices are discussed and compared with planer devices. Finally, progress towards photonic and optoelectronic integrated circuits is addressed. 436 pp. Englisch.…

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Limnology is increasingly concerned with water supply and the relation of man to aquatic environments. Without the continued availability of pure water, all progress in technology and other fields of human life will be to no avail. The global problems concerning clear water are already extremely pressing. More limnology knowledge is needed to solve these problems. The responsibility of man to save water and to take more intensive care of the environment is raised in many of the papers, in this book. This emphasizes the necessary and unquestionable relevance of limnology to human society. Too often the abuse of water usage reflects the neglect of scientific results. Limnologists have a responsibility to ensure that administrators understand what is going on. The coverage of the book is wide, including papers on microbiology to engineering sciences. The biology of waters is handled at both species and ecosystem levels. The geographical distribution of topics ranges from the tropics to northern temperate areas. In fact, limnology is increasingly becoming a science which is, rightly, relevant to everyday life, not just an academic subject. 512 pp. Englisch.…
