Versickerungsfähige Verkehrsflächen: Anforderungen, Einsatz und Bemessung

by S. Borgwardt A. Gerlach M. Köhler

Kanalnetzüberlastungen, Grundwasserabsenkungen und Hochwasserspitzen sind nur einige negative Auswirkungen der Versiegelung auf den natürlichen Wasserhaushalt. Gerade die neueren Entwicklungen hinsichtlich der Neufassung von Bodenschutzgesetzgebung, Landeswassergesetzen und kommunalen Abwassersatzungen zur Förderung des schonenden Umgangs mit Boden und Wasser lassen die Bedeutung von ökologischen Bauweisen immer wichtiger erscheinen. Der Einsatz versickerungsfähiger Verkehrsflächenbefestigungen ist hierbei ein zunehmend unentbehrlicher Baustein, um Regenwasser wieder naturnah zu bewirtschaften und damit die weitreichenden Folgen der Versiegelung zu verringern. Beim Einsatz versickerungsfähiger Befestigungssysteme sollen aufgrund ihrer Konstruktion Niederschläge direkt auf der Fläche aufgenommen und somit durch verringerte Oberflächenabflüsse die Kanalisation entlastet und die Versiegelung vermindert werden.

Versteinerte Urkunden: Die Paläontologie als Wissenschaft vom Leben in der Vorzeit (Verständliche Wissenschaft #81)

by E. Thenius

Gerne ist der Unterzeichnete der Aufforderung des Heraus­ gebers gefolgt, im Rahmen der Reihe "Verständliche Wissenschaft" einen Band über die Paläontologie zu verfassen. Der von Prof. Dr. E. Dacque im Jahre 1928 veröffentlichte Band "Das fossile Lebewesen - Eine Einführung in die Versteinerungskunde" ist längst vergriffen. Außerdem erschien in Anbetracht der Fort­ schritte der Paläontologie und der Nachbarwissenschaften im Laufe der letzten Jahrzehnte, die nicht nur zu neuen Erkenntnissen geführt, sondern auch entscheidend zur Lösung einst offener Probleme beigetragen haben, eine neue, allgemein verständliche Darstellung dieses Wissensgebietes notwendig. Damit sind auch Sinn und Zweck dieses Bandes klar umrissen. Es ist keine systematisch oder chronologisch geordnete Übersicht über die paläontologischen Urkunden, sondern der Versuch, auch weiteren Leserkreisen eine Vorstellung von der Bedeutung, den verschiedenen Methoden und den Zielen, aber auch von den Grenzen paläontologischer Forschung zu vermitteln. Wenn dies gelungen und damit auch dem Nichtfachmann gezeigt ist, daß die Paläontologie gegenwärtig alles andere als eine reine Museums­ wissenschaft darstellt, so ist der Zweck dieser Zeilen erreicht. Denn die Paläontologie besitzt, wie im Folgenden gezeigt werden soll, nicht nur große Bedeutung für die Geologie in der Praxis (durch die Mikropaläontologie und Palynologie), sondern ist vor allem auch für die Biologie bei der Beurteilung stammesgeschicht­ licher Fragen von grundsätzlicher Wichtigkeit.

Vertex Operators in Mathematics and Physics: Proceedings of a Conference November 10–17, 1983 (Mathematical Sciences Research Institute Publications #3)

by J. Lepowsky S. Mandelstam I. M. Singer

James Lepowsky t The search for symmetry in nature has for a long time provided representation theory with perhaps its chief motivation. According to the standard approach of Lie theory, one looks for infinitesimal symmetry -- Lie algebras of operators or concrete realizations of abstract Lie algebras. A central theme in this volume is the construction of affine Lie algebras using formal differential operators called vertex operators, which originally appeared in the dual-string theory. Since the precise description of vertex operators, in both mathematical and physical settings, requires a fair amount of notation, we do not attempt it in this introduction. Instead we refer the reader to the papers of Mandelstam, Goddard-Olive, Lepowsky-Wilson and Frenkel-Lepowsky-Meurman. We have tried to maintain consistency of terminology and to some extent notation in the articles herein. To help the reader we shall review some of the terminology. We also thought it might be useful to supplement an earlier fairly detailed exposition of ours [37] with a brief historical account of vertex operators in mathematics and their connection with affine algebras. Since we were involved in the development of the subject, the reader should be advised that what follows reflects our own understanding. For another view, see [29].1 t Partially supported by the National Science Foundation through the Mathematical Sciences Research Institute and NSF Grant MCS 83-01664. 1 We would like to thank Igor Frenkel for his valuable comments on the first draft of this introduction.

Vertical Reference Systems: IAG Symposium Cartagena, Colombia, February 20–23, 2001 (International Association of Geodesy Symposia #124)

by Alan H. Dodson Luiz P. S. Fortes Laura Sanchez Pedro Sandoval Hermann Drewes

The Symposium on Vertical Reference Systems (VeReS) was initiated on the occasion of the XXII General Assembly of the International Union of Geodesy and Geophysics (IUGG), Birmingham 1999, by Professor Dr. Wolfgang Torge, Past President of the International Association of Geodesy (lAG) and representative of lAG to the Pan-American Institute of Geography and History (PAIGH). The idea was to organise another joint symposium of lAG and PAIGH like the previous one held during the XX IUGG General Assembly at Vienna, Austria, in 1991. Good reasons for such a joint symposium were the great success and the ongoing activities of the Project on the South American Geocentric Reference System (Sistema de Referencia Geocentrico para America del Sur, SIRGAS) being sponsored by lAG and PAIGH since 1993. The SIR GAS Project (Working Group I) had presented a continental South American reference frame of 58 stations during the lAG Scientific Assembly at Rio de Janeiro, in 1997. This reference frame was already adopted by several South American countries as the basis for their new national horizontal geodetic datums (SIRGAS Working Group II). To overcome the problems of the heterogeneous vertical (height) datums between the individual countries, SIRGAS had installed its Working Group III "Vertical Datum" in 1997. As the discussion on the unification of vertical reference systems is also going on in lAG and other bodies of science and practice, it was decided to dedicate the symposium to this topic.

Vertical Seismic Profiling and Its Exploration Potential (Modern Approaches in Geophysics #1)

by E.I. Galperin

The present book is the author's third on the subject of vertical seismic profiling (VSP). Ten years have elapsed since the pUblication of the fIrst book. During this period, VSP has become the principal method of seismic observations in boreholes and the chief method of experimental studies of seismic waves in the real earth. VSP combines borehole studies in the seismic frequency band, well velocity surveys, proximity or aplanatic surveys, all of which previously existed as separate methods. The high effectiveness ofVSP, its great practical value, the express nature and clarity of the results obtained have all contributed towards a very rapid acceptance of the method. In the USSR VSP has been used in an overwhelming majority of areas and is being used increasingly in many foreign countries as well. This has been greatly facilitated by the translation into English and the publication in the U. S. A. by the Society of Exploration Geophysicists of the book Vertical Seismic Profiling (Tulsa, Oklahoma, 1974). As the method has become more familiar, it has attracted growing interest outside the USSR This has been substantiated by the special seminar on VSP (Oklahoma, 1979) which was organized for 22 U. S. companies and universities and presented by the author.

Vertical Urbanism: Designing Compact Cities in China (China Perspectives)

by Zhongjie Lin José L. S. Gámez

Studies of compact cities have evolved along with the rising awareness of climate change and sustainable development. Relevant debates, however, reveal that the prevailing definitions and practices of compact cities are tied primarily to traditional Western urban forms. This book reinterprets "compact city", and develops a ground-breaking discourse of "Vertical Urbanism", a concept that has never been critically articulated. It emphasizes "Vertical Urbanism" as a dynamic design strategy instead of a static form, distinguishing it from the stereotyped concept of "vertical city" or "towers in the park" dominant in China and elsewhere, and suggests its adaptability to different geographic and cultural contexts. Using Chinese cities as laboratories of investigation, this book explores the design, ecological, and sociocultural dimensions of building compact cities, and addresses important global urban issues through localized design solutions, such as the relationship between density and vitality, the integration of horizontal and vertical dimensions of design, and the ecological and social adaptability of combinatory mega-forms. In addition, through discussions with scholars from the United States, China, and Japan, this book provides an insight into the theoretical debates surrounding "compact city" and "Vertical Urbanism" in the global context. Scholars and students in architecture and urban planning will be attracted by this book. Also, it will appeal to readers with an interest in urban development and Asian studies.

Very Long Baseline Interferometry: Techniques and Applications (Nato Science Series C: #283)

by Marcello Felli Ralph E. Spencer

The quest for high resolution has preoccupied radio astronomers ever since radio waves were first detected from space fifty years ago. This venture was par­ ticularly stimulated by the discovery of quasars, and led to the development of interferometer techniques using baselines of transglobal dimensions. These meth­ ods have become known as Very Long Baseline Interferometry (VLBI). Arrays of radio telescopes situated all over the Earth (or even in space) are regularly used for researches in radio astronomy, reaching resolutions as small as a fraction of a milli arcsecond. The technique also allows the measurement of the positions of the radio telescopes to a few millimeters and so VLBI has become a major tool in geodesy and the study of the rotation of the Earth. VLBI has now passed the pioneer stage and is becoming a standard facility available to astronomers and geodesists, requiring the coordination of the operations of indpendently owned radio telescopes around the world. In Europe observatories from England, Federal Republic of Germany, France, Italy, Poland, Sweden and The Netherlands are coordinated in their VLBI activity by the European VLBI Network Consortium (EVN). The Programme Committee of the EVN allocates time to scientific projects on a routine basis three times a year. The Unites States has a similar arrangement of a network of independent radio observatories, and joint experiments using 'Global Network' are often made.

Very Slow Flows of Solids: Basics of Modeling in Geodynamics and Glaciology (Mechanics of Fluids and Transport Processes #7)

by L. A. Lliboutry

This book is written primarily for Earth scientists faced with problems in thermo­ mechanics such as the flow and evolution of ice-sheets, convection currents in the mantle, isostatic rebound, folding of strata or collapse of cavities in salt domes. Failure, faults, seismic waves and all processes involving inertial terms will not be dealt with. In general such scientists (graduate students beginning a Ph. D. for instance) have too small a background'in continuum mechanics and in numerical computation to model conveniently these problems, which are not elementary at all. Most of them are not linear, and therefore seldom dealt with in treatises. If the study of reality were clearly cut into two successive steps: first to make a physical model, setting up a well-posed problem in thermo-mechanics, and second to solve it, the obvious solution would be to find a specialist in computational mechanics who could spend enough time on a problem which, although maybe crucial for on-going fundamental research, has little practical interest in general, and cannot be considered properly as a noteworthy progress in Mechanics. But this is not the way Science develops. There is a continuous dialectic between the building up of a model and its mathematical treatment. The model should be simple enough to be tractable, but not oversimplified. Its sensitivity to the different components it is made of should be investigated, and more thought is needed when the results contradict hard facts.

Vesuvius: A Biography

by Alwyn Scarth

The volcano that has fascinated scientists, writers, and poets for two millenniaCapricious, vibrant, and volatile, Vesuvius has been and remains one of the world's most dangerous volcanoes. In its rage, it has destroyed whole cities and buried thousands alive. In its calm, its ashes have fertilized the soil, providing for the people who have lived in its shadows. For over two millennia, the dynamic presence of this volcano has fascinated scientists, artists, writers, and thinkers, and inspired religious fervor, Roman architecture, and Western literature. In Vesuvius, Alwyn Scarth draws from the latest research, classical and eyewitness accounts, and a diverse range of other sources to tell the riveting story of this spectacular natural phenomenon.Scarth follows Vesuvius across time, examining the volcano's destruction of Pompeii and Herculaneum in 79 A.D., its eruptions during the Counter-Reformation that were viewed as God's punishment of sinners, and the building of the world's first volcano observatory on Vesuvius in the 1840s. Scarth explores the volcano's current position overlooking a population of more than three million people and the complex attitudes maintained by the residents, at once reverent, protective, and fearful. He also considers the next major eruption of Vesuvius, which experts have indicated could be the most powerful since 1631. The longer Vesuvius remains dormant, the more violent its reawakening will be, and despite scientific advances for predicting when this might occur, more people are vulnerable than ever before.Exploring this celebrated wonder from scientific, historical, and cultural perspectives, Vesuvius provides a colorful portrait of a formidable force of nature.
