It presents the results of the ComBoNDT European project, which aimed at the development of more secure, time- and cost-saving extended non-destructive inspection tools for carbon fiber reinforced plastics, adhered surfaces and bonded joints. The book reports the optimal use of composite materials to allow weight savings, reduction in fuel consumptions, savings during production and higher cost efficiency for ground operations.
Kongruentes Lithiumniobat zeichnet sich durch eine ausgepragte intrinsische Defektstruktur aus. Diese fuhrt zur Ausbildung einer Vielzahl polaronischer Zustande. Als Polaron wird dabei ein Quasiteilchen bestehend aus einem Ladungstrager und einer selbstinduzierten Gitterverzerrung bezeichnet. Durch ihre schnelle optische Anregung sind Polaronen fur viele Anwendungen interessant. Die vorliegende Arbeit untersucht die Moglichkeit der Aufzeichnung holographischer Gitter auf der Basis raumlich modulierter Dichten von Polaronen in thermisch reduziertem Lithiumniobat. Hierzu wird in einem Zweistrahl-Interferometer eine modulierte Intensitatsverteilung aus einem einzelnen Nanosekunden-Laserpuls zur...
»Als der Sturm kam« | Die Hamburger Sturmflut von 1962 Deiche brechen im Minutentakt, Straßen werden zu reißenden Flüssen, Menschen sind vom Wasser eingeschlossen. Es ist die Stunde der Wahrheit. Für die spannende Reihe »Schicksalsmomente der Geschichte« erzählt Anja Marschall in ihrem historischen Roman von Hamburgs dramatischsten Stunden seit dem Zweiten Weltkrieg: Als die Flutkatastrophe über Hamburg hereinbricht, wird die Schreibkraft Marion der Leitung von Polizeisenator Helmut Schmidt unterstellt. Ein Krisenstab muss eingerichtet, NATO-Verbündete um Hilfe gebeten, Hubschraubereinsätze geplant werden. Marion kämpft gegen Müdigkeit und hat Angst um ihre bettlägerige Mutter...
November 1932. With the German economy in ruins and street battles raging between political factions, the Weimar Republic is in its death throes. Its elderly president Paul von Hindenburg floats above the fray, inscrutably haunting the halls of the Reichstag. In the shadows, would-be saviours of the nation vie for control. The great rivals are the chancellors Franz von Papen and Kurt von Schleicher. Both are tarnished by the republic's all-too-evident failures. Each man believes he can steal a march on the other by harnessing the increasingly popular National Socialists - while reining in their most alarming elements, naturally. Adolf Hitler has ideas of his own. But if he can't impose discipline on his own rebellious foot-soldiers, what chance does he have of seizing power?
‘Jürgen Habermas’, wrote the American philosopher Ronald Dworkin on the occasion of the great European thinker’s eightieth birthday, ‘is not only the world’s most famous living philosopher. Even his fame is famous.’ Now, after many years of intensive research and in-depth conversations with contemporaries, colleagues and Habermas himself, Stefan Müller-Doohm presents the first comprehensive biography of one of the most important public intellectuals of our time. From his political and philosophical awakening in West Germany to the formative relationships with Adorno and Horkheimer, Müller-Doohm masterfully traces the major forces that shaped Habermas’s intellectual developme...
Explains the current weakness of democratic polities by addressing paradoxes in constitutional democracy and its theoretical foundations.
Using a methodology that both analyzes particular constitutional texts and theories and reconstructs their historical evolution, Chris Thornhill examines the social role and legitimating status of constitutions from the first quasi-constitutional documents of medieval Europe, through the classical period of revolutionary constitutionalism, to recent processes of constitutional transition. A Sociology of Constitutions explores the reasons why modern societies require constitutions and constitutional norms and presents a distinctive socio-normative analysis of the constitutional preconditions of political legitimacy.
Is interrogational torture effective? What do we mean by "effective"? How brutal can torture get and be considered justifiable? In this book, John Schiemann adopts game theory in an attempt to answer these questions, walking the reader through the logic of interrogational torture - and finding that it is far more brutal than proponents believe.
