Interfacial behaviour of surfactants and enzymes: studies at model surfaces

Popular Abstract in Swedish Denna avhandling presenterar resultat från experimentella studier av tensiders och enzymers beteenden vid modellytor. Ellipsometri var den i huvudsak använda tekniken i dessa undersökningar. Studier av tensidadsorption i statiska och dynamiska vätningssituationer initierades för att undersöka adsorptionsbeteenden i närheten av trefaslinjen under dynamisk vätning. I falThis thesis presents results from experimental studies of the interfacial behaviour of surfactants and enzymes at model surfaces. The main technique used throughout the work was ellipsometry. Studies of surfactant adsorption in static and dynamic wetting situations were performed to investigate adsorption behaviour close to the three-phase contact line (tpl) during dynamic wetting. It was demonst

A source of high-velocity white dwarfs

We investigate whether the recently observed population of high-velocity white dwarfs can be derived from a population of binaries residing initially within the thin disc of the Galaxy. In particular, we consider binaries where the primary is sufficiently massive to explode as a Type II supernova. A large fraction of such binaries are broken up when the primary then explodes as a supernova, owing

Visualizing Library and Information Science concept spaces through keyword and citation based maps and clusters

Co-citation analysis has been widely accepted as the foremost method for bibliometric mapping of research fields, whereas analyses based on keywords has been discussed, without gaining any overall acceptance. There is, however advantages with keywords, such as being understandable by others than those immediately connected to the field analyzed. This study aims at testing the relation between keyw

Understanding the First Hundred Years of Christian Identity

After stating that there did exist an early Christ-believing movement in the first century CE, distinct enough to be investigated, the chapter gives a review of recent scholarly approaches to what "Christian identity" is. Answers range from a textual reality only, to an ideological construct, or rhetorical construction with social effectiveness, or an autonomous inner structure of the semiotic sys
