Die hier betrachtete transatlantische Massenauswanderung im 19. Jahrhundert, die selbst nur ein Ausschnitt der Bevölkerungsbewegung in Europa war, stellte zahlenmäßig den Höhepunkt der europäischen Expansionsgeschichte der Neuzeit dar. In den Hungerjahren 1816/17 bis zum Ausbruc…
Die hier betrachtete transatlantische Massenauswanderung im 19. Jahrhundert, die selbst nur ein Ausschnitt der Bevölkerungsbewegung in Europa war, stellte zahlenmäßig den Höhepunkt der europäischen Expansionsgeschichte der Neuzeit dar. In den Hungerjahren 1816/17 bis zum Ausbruc…
In this work, contributes to the optimization of local continuous fiber reinforcement patches, under consideration of manufacturing constraints. This approach requires specific optimization strategies. Therefore, an multi-objective optimization strategy for the placement of loca…
We have developed a microfluidic two-layered channel system based on polycarbonate to investigate the transmigration of cancer cells under flow conditions and defined shear rate using live cell microscopy. The two layers are separated by a porous membrane with an endothelial mon…
In this thesis, different laser based methods to produce high density peptide arrays were developed. They use laser radiation to structure special micro particles with amino acids. The particles are heated and fused to a substrate (Combinatorial Laser Fusing) or they are transfe…
Are discount chains responsible for 'sellout' of the classical city? What kind of city do they endorse and what forms of urbanization do they really engender? Can planning practices still intervene to steer the course of urban development? How can concepts of sustainable archite…
Fictionally depicted technology appears to be dominated by gender stereotypes that reproduce common clichés and are based on the opposition of traditional, gender-associated characteristics. Thus, masculinity represents the technological principle whereas femininity is associate…
