  2. 1. Computer Assisted Video Microscopy : in Characterization of Capillary Ensembles

    Author : Claes Asker; Linköpings universitet; []
    Keywords : computer assisted video microscopy; capillary loops; capillary ensembles; skin microcirculation; triangulation; nearest neighbour; MEDICINE;

    Abstract : This thesis focuses on evaluation and analysis of capillary microcirculatory changes in the skin, that can be improved and extended by computer assisted video microscopy. Capillary microscopy has been used extensively, both in clinical practice and research, to study different phenomena in the microvasculature of the skin, mainly in the nailfold of fingers and toes where a large portion of the capillary loop can be observed.

  5. 3. Moving out, moving up, becoming employed : Studies in the residential segregation and social integration of immigrants in Sweden

    Author : Kati Kadarik; Roger Andersson; John Östh; Anneli Kährik; David Manley; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Residential segregation; social integration; residential mobility; neighbourhood effects; k-nearest neighbour; Sweden; Social and Economic Geography; Kulturgeografi;

    Abstract : This thesis investigates the complex relationship between residential segregation and social integration. The dominant discourse in Sweden and Europe sees residential segregation as hindering socioeconomic and cultural integration, creating parallel societies and even threatening the social cohesion of European societies.

  6. 4. Structure-dynamics relationships in perovskite oxyhydrides and alkali silanides

    Author : Carin Eklöf-Österberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hydrogen storage material; long range diffusion; oxyhydride; neutron scattering; localized motion; hydride ion conduction; hydrogen dynamics;

    Abstract : This thesis focuses on investigations of the local structure and dynamics of two classes of hydrogen-containing, energy relevant, materials; perovskite type oxyhydrides BaTiO3-xHx and alkali silanides ASiH3 (A = K and Rb). In the area of oxyhydrides, which are of relevance for the development of electrolytes in fuel cells and batteries, the aim is to elucidate the dynamics and electronic character of the hydrogen species in the materials.

  7. 5. First-principles study of spin-flip transition in Fe-Ni invar alloys

    Author : François Liot; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : More than a hundred years ago, Guillaume discovered that the alloy Fe65Ni35, at equilibrium under normal pressure, was invar. Indeed, its thermal expansion coefficient was anomalously small over a wide temperature interval. It is now known that the invar effect in this alloy is related to magnetism. READ MORE
