Taschenbuch. Condizione: Neu. Neuware -Disordered systems are statistical mechanics models in random environments. This lecture notes volume concerns the equilibrium properties of a few carefully chosen examples of disordered Ising models. The approach is that of probability theory and mathematical physics, but the subject matter is of interest also to condensed matter physicists, material scientists, applied mathematicians and theoretical computer scientists. (The two main types of systems considered are disordered ferromagnets and spin glasses. The emphasis is on questions concerning the number of ground states (at zero temperature) or the number of pure Gibbs states (at nonzero temperature). A recurring theme is that these questions are connected to interesting issues concerning percolation and related models of geometric/combinatorial probability. One question treated at length concerns the low temperature behavior of short-range spin glasses: whether and in what sense Parisi's analysis of the meanfield (or 'infinite-range') model is relevant. Closely related is the more general conceptual issue of how to approach the thermodynamic (i.e., infinite volume) limit in systems which may have many complex competing states. This issue has been addressed in recent joint work by the author and Dan Stein and the book provides a mathematically coherent presentation of their approach.)Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 100 pp. Englisch.

Buch. Condizione: Neu. Neuware -Conceptually unsavoury, airway mucus is vital to homeostasis in the respiratory tract. In contrast, when abnormal, mucus contributes significantly to the pathophysiology of a number of severe bronchial diseases, including asthma, chronic bronchitis and cystic fibrosis. This volume provides wide ranging and in-depth coverage of the scientific and clinical aspects of airway mucus. It commences with introductory chapters which address the biochemical and molecular biological basis of airway mucus and continues with comprehensive coverage of the various physiological and rheological aspects of respiratory secretions. The clinical aspects of the topic are then considered, with chapters discussing the involvement of mucus secretions in bacterial infection and in hypersecretory diseases of the airway. The volume concludes with a discussion of the therapeutic aspects of the topic, both in terms of the possible approaches to the treatment of mucus hypersecretion and the interaction of these drugs with airway mucus. Written by leading experts in the field, each contribution provides a comprehensive review of its particular subject. Reflecting the latest advances in this important area of respiratory research, this volume will be of great interest to scientists and clinicians working in the field of airway secretions and related areas.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 404 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Ihr Fell gleicht dem der Mäuse, doch sie fliegen wie Vögel ¿ und das vornehmlich nachts. Verhalten und Aussehen der Fledermäuse erregten bereits im Mittelalter Misstrauen, so dass sie seither mit einem schlechten Ruf zu kämpfen haben. Wenn man sich jedoch näher mit ihnen beschäftigt, erkennt man schnell, dass es sich um außergewöhnliche Tiere mit verblüffenden Eigenschaften handelt.So sind sie nicht nur virtuose Flieger, für die Saltos, Sturz- und Steigflüge kein Problem sind, sondern auch vorbildhafte Energiesparer, wenn sie in ihren Höhlen als dicker Cluster zusammenhängen ¿ kopfunter, versteht sich. Ja, warum eigentlich kopfunter Ein Geheimnis, auf das die Wissenschaftler bis jetzt noch keine befriedigende Antwort gefunden haben. Jürgen Gebhards Buch besticht durch seine außergewöhnlichen Fotos, von denen die meisten noch nie veröffentlicht wurden. Darüber hinaus ist es ihm gelungen, nicht nur eine Vielzahl neuer Informationen zusammenzustellen, insbesondere zum Thema Fortpflanzung, sondern auch seiner Bewunderung und Leidenschaft für diese fliegenden Säugetiere Ausdruck zu verleihen.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 384 pp. Deutsch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Die Intensivierung der Anbau- und Bewirtschaftungsmethoden führte in den vergangenen 50 Jahren zu einer Verarmung der Biodiversität in mitteleuropäischen Landwirtschaftsgebieten. Durch landeseigene Gesetze und mit der Ratifizierung der Konvention über die biologische Vielfalt (Agenda 21) ist die Schweiz verpflichtet, Massnahmen zur Erhaltung und Förderung der Biodiversität zu treffen. Als eine dieser Massnahmen wurden ökologische Ausgleichsflächen eingeführt, mit denen die natürliche Artenvielfalt im Landwirtschaftsgebiet gefördert werden sollte. Die Bewirtschafter erhalten für bestimmte Arten von ökologischen Ausgleichsflächen finanzielle Entschädigungen, während der Unterhalt von anderen ökologischen Ausgleichsflächen und Landschaftsstrukturelemente vom Bund nicht unterstützt wird. Anhand von veröffentlichten wissenschaftlichen Studien wird die Bedeutung der verschiedenen Arten von ökologischen Ausgleichsflächen und Landschaftsstrukturelementen für die Erhaltung und Förderung der Biodiversität untersucht und mit der heutigen Entschädigungspraxis verglichen. Mit dieser Arbeit wird die Grundlage für eine objektive Beurteilung und Überprüfung der bestehenden Ausgleichsbeiträge geschaffen. Änderungen in den finanziellen Entschädigungen werden vorgeschlagen, damit die natürliche Arten- und Strukturvielfalt im Landwirtschaftsgebiet besser gefördert werden kann. 101 pp. Deutsch.

Neuware -The Conference on 'Statistical Science', held in Monte Verita (Switzerland) on 18/20 November 1996, was intended to honour the memory of Stefano Franscini at the occasion of the bicentennial of his birth (1796-1996). It was jointly organized by the Swiss Federal Institute of Technology in Lausanne, the Swiss Federal Statistical Office and the University of Geneva. These proceedings gather a selected collection of contributions presented by statisticians from universities, research institutes and national statistical services of Europe, North America and Asia. Part I focuses on a historical appreciation of Stefano Franscini's life and work. Authors develop a deep analysis of the historical context, the political action, the scientific achievement and the intellectual legacy of the founding father of Swiss official statistics. The reader thus has an opportunity to appreciate the various facets of this exceptional man who not only drew the first comprehensive statistical portrait of Switzerland but also established the foundations for modem educational and political institutions. Part II groups papers on the relationship between statistical science and official statistics. Authors analyse the historical background, current context and new perspectives of co-operation between scientific research and official statistical services. They show how the relationship between both partners has evolved over the past decades, stressing certain prerequisites and opportunities for effective of rigourous interaction between academia's scientific activity and the production statistical information.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 260 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Most organisms and populations have to cope with hostile environments, threatening their existence. Their ability to respond phenotypically and genetically to these challenges and to evolve adaptive mechanisms is, therefore, crucial. The contributions to this book aim at understanding, from a evolutionary perspective, the impact of stress on biological systems. Scientists, applying different approaches spanning from the molecular and the protein level to individuals, populations and ecosystems, explore how organisms adapt to extreme environments, how stress changes genetic structure and affects life histories, how organisms cope with thermal stress through acclimation, and how environmental and genetic stress induce fluctuating asymmetry, shape selection pressure and cause extinction of populations. Finally, it discusses the role of stress in evolutionary change, from stress induced mutations and selection to speciation and evolution at the geological time scale. The book contains reviews and novel scientific results on the subject. It will be of interest to both researchers and graduate students and may serve as a text for graduate courses.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 348 pp. Englisch.
