In Krisenzeiten: Quo vadis, Architektur? Angetrieben vom Wunsch, angesichts von Krisen bessere Welten zu erschaffen, versuchen Architekt: innen, Gesellschaft, Städte und Wohnformen neu zu denken, die Architektur und ihre Materialität zu erneuern - und prägen damit eine neue Ãsthetik. Denn Krisen eröffnen als "Kippmomente" neue Perspektiven: Anhand historischer wie zeitgenössischer Projekte untersucht Susanne Stacher unterschiedliche Strategien in der Architektur. Ansätze aus Wissenschaft und Philosophie (u. a. Pierre-Henri Castel, Hartmut Rosa) ermöglichen es, Vorstellungen von Fortschritt, Wachstum, Natur, Gesellschaft zu hinterfragen, die in den vorgestellten Architekturprojekten sichtbar werden. Das Buch spannt einen weiten historischen Bogen und ist ein Plädoyer, über die Rolle von Architektur und Städtebau in Zeiten ökologischer Krisen nachzudenken. Eine historische und philosophische Betrachtung von Architektur in Krisenzeiten Vom Archaismus über das Streben nach Entschleunigung, Erschaffung durch Zerstörung bis zur Wiederverzauberung der Welt Projekte/Konzepte von Hans Hollein, Ebenezer Howard, Bjarke Ingels, Le Corbusier, Adolf Loos, Paul Otlet, Bernard Rudofsky u. a.
Although he was one of the most important figures of the Modern Movement in emigration Karol Schayer is little known outside Lebanon. Using a wealth of previously unpublished original documents and illustrations this monograph reconstructs Schayer s early career in Poland (1927 39), his years as an emigre in Turkey and Palestine (1939 46), and then his very successful and important creative period in architecture and furniture design in Lebanon (1946 70) with his successive partners Fritz Gotthelf, Bahij Makdisi and Wassek Adib. Thus the lifework of this modernist architect becomes understandable for the first time, and is shown to be clearly on a par with analogous achievements of the period around the world. This comprehensive and richly illustrated monograph is the result of many years of tireless research by George Arbid, Associate Professor at the American University of Beirut.

Opioids are not always the most suitable analgesic therapy, despite being effective in the treatment of a wide variety of painful conditions. Many non-opioid analgesics are frequently preferable for the treatment of mild or moderate pain, because of their lower incidence of side-effects, or beacause they have a more relevant site of action.

"Transparency" is a key text and required reading for all students of modern architecture. As members of the 1950s group known as the "Texas Rangers", Colin Rowe and Robert Slutzky tested new methods for teaching and developing architectural design skills. Through their exploration of the common basis of modern art and architecture they identified and elaborated on the concept of transparency as a fundamental principle of spatial organisation, beyond the curtain wall. Their essay titled Transparency, first published in 1964, provided the theoretical and didactical fundament, exemplified and illustrated by 2 of Le Corbusier s buildings.

Der 1964 publizierte Aufsatz Transparenz von Colin Rowe und Robert Slutzky gehört zu den Grundlagentexten der Architektur-Ausbildung unserer Zeit. Rowe und Slutzky bildeten in den fünfziger Jahren zusammen mit John Hejduk, Werner Seligmann und Bernhard Hoesli die Architektengruppe der «Texas Rangers» der University of Texas in Austin. Im Rahmen ihrer Lehrtätigkeit versuchten sie eine neue Methode für den architektonischen Entwurf zu entwickeln. Der Text entwickelt gegen die bloÃe Durchsichtigkeit einer Curtain Wall die übertragene Bedeutung von Transparenz als einer räumlichen Ordnung. Die deutsche Ausgabe von Transparenz erschien erstmals 1968 als kritische Edition des Instituts für Geschichte und Theorie der Architektur (gta) der ETH Zürich mit einem Kommentar von Bernhard Hoesli. Die vierte Auflage ist durch eine neue Einführung von Werner Oechslin erweitert, in der er vor allem Bernhard Hoeslis Bedeutung für die Entstehung und Verbreitung von Transparenz kritisch würdigt.

The present lectures are based on a course deli vered by the authors at the Uni versi ty of Bucharest, in the winter semester 1985-1986. Without aiming at completeness, the topics selected cover all the major questions concerning hyponormal operators. Our main purpose is to provide the reader with a straightforward access to an active field of research which is strongly related to the spectral and perturbation theories of Hilbert space operators, singular integral equations and scattering theory. We have in view an audience composed especially of experts in operator theory or integral equations, mathematical physicists and graduate students. The book is intended as a reference for the basic results on hyponormal operators, but has the structure of a textbook. Parts of it can also be used as a second year graduate course. As prerequisites the reader is supposed to be acquainted with the basic principles of functional analysis and operator theory as covered for instance by Reed and Simon [1]. A t several stages of preparation of the manuscript we were pleased to benefit from proper comments made by our cOlleagues: Grigore Arsene, Tiberiu Constantinescu, Raul Curto, Jan Janas, Bebe Prunaru, Florin Radulescu, Khrysztof Rudol, Konrad Schmudgen, Florian-Horia Vasilescu. We warmly thank them all. We are indebted to Professor Israel Gohberg, the editor of this series, for his constant encouragement and his valuable mathematical advice. We wish to thank Mr. Benno Zimmermann, the Mathematics Editor at Birkhauser Verlag, for cooperation and assistance during the preparation of the manuscript.
V.G. Maz'ya is author or co-author of more than 300 scientific works on various fields of functional analysis, function theory, numerical analysis, partial differential equations and their application. This collection of articles in two volumes is dedicated to him on the occasion of his 60th birthday. The first volume contains surveys that show his enormous productivity and the large variety of his work. The second volume consists of artivles by outstanding experts on various problems in functional analysis, potential theory, linear and nonlinear partial differential equations, theory of function spaces and numerical analysis.
During the week of August 31 - September 4, 1998, a conference in honour of Vladimir Maz'ya was held in Rostock as a satellite meeting of the World Congress of Mathematicians. It was sponsored by the German Research Founda- tion (Deutsche Forschungsgemeinschaft) and the Ministry of Education and Cul- tural Affairs of the land Mecklenburg-Vorpommern. During his forty year career Maz'ya contributed to so many areas of mathematical analysis that such a broad topic of the conference as "Functional Analysis, Partial Differential Equations and Applications" sounds quite nat al. The conference was organized by the Depart- ment of Mathematics of the University of Rostock and the Weierstrass Institute of Applied Analysis and Stochastics in Berlin on the occasion of his 60th birth- day. For many years Maz'ya was connected with mathematicians from Berlin and Rostock through his work in potential theory, in differential and pseudodifferen- tial equations and in approximation theory. In 1990 he was awarded an honorary doctorate by the University of Rostock. Shortly before the meeting, one of its organizers, an outstanding mathematician and Maz'ya's dear friend, Siegfried Pr6Bdorf died. This was a heavy loss for the and for the conference in particular. During the German mathematical community meeting the rector of the University of Rostock, Prof. Wildenhain, the director of the Weierstrass Institute, Prof. Sprekels, and Prof. Maz'ya remembered S. Pr6Bdorf very warmly. The conference was attended by 109 mathematicians from 21 countries, and the program included 24 invited lectures and 63 short communications.

Anguinomorph lizards have attracted the attention of various workers for several reasons. They form a lacertilian infraorder well dermed by the subdivision of their tongue into a retractile fore-portion and a broad, elastic hind portion. The long, independent evolutionary history is documented by a rich fossil record (Hoff stetter, 1962 a). The lizards referred to the Anguinomorpha are subdivided into two suprafamilies, the Anguinoidea and the Platynota. The Anguinoidea comprise three families, the Anguidae, Xenosauridae and Anniellidae. The Platynota comprise seven families, the Helodermatidae, Parasaniwidae, Lanthanotidae, Dolichosauridae, Aigialosauridae, Mosasauridae and Varanidae. The Anguinomorpha exhibit a wide range of adaptation from the burrowing An niellidae to the Dolichosauridae, Aigialosauridae and Mosasauridae, inhabitants of the Cretaceous seas. Since the days of Nopsca (1903, 1908, 1923), Janesch (1906) and Fejervary (1918) they stand as ancestors of snakes, a view which was accepted by Camp (1923) and McDowell and Bogert (1954, see also McDowell, 1972)."

Large structures such as factories, gymnasia, concert halls, bridges, towers, masts and chimneys can be detrimentally affected by vibrations. These vibrations can cause either serviceability problems, severely hampering the user's comfort, or safety problems. The aim of this book is to provide structural and civil engineers working in construction and environmental engineering with practical guidelines for counteracting vibration problems. Dynamic actions are considered from the following sources of vibration: - human body motions, - rotating, oscillating and impacting machines, - wind flow, - road traffic, railway traffic and construction work. The main section of the book presents tools that aid in decision-making and in deriving simple solutions to cases of frequently occurring "normal" vibration problems. Complexer problems and more advanced solutions are also considered. In all cases these guidelines should enable the engineer to decide on appropriate solutions expeditiously. The appendices of the book contain fundamentals essential to the main chapters.
