11. Stability analysis of channel flow laden with small particles
Sammanfattning : This thesis deals with the stability of particle laden flows. Both modal and non-modal linear analyses have been performed on two-way coupled particleladen flows, where particles are considered spherical, solid and either heavy or light. When heavy particles are considered, only Stokes drag is used as interaction term. LÄS MER
12. New Reactions with Allyl- and Allenylboron Reagents : Transition-Metal-Catalyzed and Transition-Metal-Free Carbon-Carbon Bond Formation Processes
Sammanfattning : Organoboron compounds have been widely used in carbon-carbon bond formation reactions in organic synthesis and catalysis. This thesis is focused on cross-coupling reactions of allyl-, allenylboronic acids and their ester derivatives via transition metal catalysis or transition-metal-free processes. LÄS MER
13. Transition Metal Nitrides : Alloy Design and Surface Transport Properties using Ab-initio and Classical Computational Methods
Sammanfattning : Enhanced toughness in brittle ceramic materials, such as transition metal nitrides (TMN), is achieved by optimizing the occupancy of shear-sensitive metallic electronic-states. This is the major result of my theoretical research, aimed to solve an inherent long-standing problem for hard ceramic protective coatings: brittleness. LÄS MER

15. Reportaget som kom av sig : en analys av reportaget som textform utifrån produktionsperspektivet och sändarrollen med betoning på reporterns personliga tonfall : en undersökning av reportaget i några landsortstidningar 1960-1985
Sammanfattning : Reportage is a generally accepted, yet poorly defined genre in Swedish newspaperterminology. It is usually associated with journalistic texts that are produced outside theroutines of daily news coverage; reportage features also have a more personal tone thanstandard news texts in that the reporter imparts his or her personal observations andperceptions of the scene in question.
