Dürrenmatt's most famous play in the German canon of literature

Business services play a major role in post-fordist economies. This paper is based on a macro-scale analysis (1980 - 1995) of the locational system of business services in Northrhine-Westphalia, a federal state in Germany. The locational system has developped in a way that the hierarchical dimension has lost importance since 1980 whereas the functional differentiation among the locations, i.e. the cities, has increased. On the whole the locational system proves to be stable.

The role of eroticism and violence in the European literature of the 'fin de siècle'

the myth of the vampires, the historical facts, Bram Stoker's novel "Dracula", the Dracula films since Murnau's "Nosferatu" till Coppola's "Dracula"

The averaged conservation laws are numerically solved for unsteady turbulent flows of compressible fluids using implicit iterative schemes. To investigate the effects of upstream vortices on the flow filed in the stator blade passages of an axial compressor, upstream vortices are modeled by a vortex shedding flow behind a circular cylinder, which moves in the transverse direction at the entrance of the stator blade row. The interface problem arising due to the relative motion of two different reference systems is handled by a novel technique, which allows the evaluation of the numerical flux at the interface also in the same way as at interior points. To validate the interface technique and to exhibit the temporal behaviour of vortices in the blade passages, some results are presented.

Der öffentliche Wohnungsbau gilt im Hinblick auf die Integration der multi-ethnischen Bevölkerung des Stadtstaates Singapur als eine der Säulen der Nation. Über ein ausgeklügeltes System der Alterssicherung macht er fast 90 Prozent der Einwohner zu Quasi-Eigentümern. Diesen Anreiz setzt Singapur gezielt für die Realisierung seines weltweit wohl einmaligen Modells der staatlich gelenkten residentiellen Integration ein. Über das Leitbild des Nation Building und das Mittel des Social Engineering steuert der Developmental State den Integrationsprozess seiner ethnisch und sozioökonomisch gemischten Bevölkerung. Das seit Januar 2001 laufende Projekt der Deutschen Forschungsgemeinschaft Öffentlicher Wohnungsbau und Stadtentwicklung in Singapur am Lehrstuhl für Kulturgeographie, Fakultät für Gesellschaftswissenschaften der Universität Duisburg (Prof. Dr. Winfried Flüchter, Institut für Geographie und Institut für Ostasienwissenschaften) zielt auf eine Analyse des residentiellen Integrationsmodells im Hinblick auf neue Aspekte für die Sozialökologie im Rahmen qualitativer Sozialforschung unter besonderer Beachtung der mikroräumlichen Dimension. Der folgende Beitrag bietet einen Ausschnitt der Ergebnisse der ersten, quantitativen Projektphase: eine Bestandsaufnahme des residentiellen Integrationsmodells auf unterschiedlichen kleinräumigen Maßstabsebenen, Grundlage für die noch bevorstehenden empirisch-qualitativen Recherchen.

This thesis reports on the study of elementary reactions of the carbon radicals C, C2 and C3 at combustion temperatures. The shockwave technologie was used to generate the necessary gas temperatures of 2500 K up to 5000 K. Fast optical measurement techniques were applied for the time resolved observation of radical reactions. For the detection of C2-radicals, a highly sensitive diagnostic was developed, based on a ring-dye-laser spectrograph. The radicals C3 and CN and the atomic species C, N, and O were measured with a CCD-Camera spectrograph and with the atomic-resonance-absorption spectroscopy. The thermal decomposition (pyrolysis) of acetylene (C2H2) was used as a source for Carbon radicals. Results of this thesis are an extension and a verification of reaction mechanisms for the pyrolysis of acetylene as well as the determination of rate coefficients for the decompostion reactions of C2H2, C2H and C2 and for the bimolecular reactions of C2 with H2, O, O2, N2 and NO.
