1. 1. Recovery-promoting factors in day centres and Clubhouses for people with psychiatric disabilities. A comparative study

   Författare :Jenny Hultqvist; aktivitet och delaktighet Psykisk hälsa; []
   Nyckelord :återhämtning; arbetsterapi; psykosocial rehabilitering; kommunal psykiatri; självkänsla; Community Mental Health Services; Recovery; Occupational Therapy; Psychosocial rehabilitation;

   Sammanfattning : The thesis aims to compare two approaches to psychosocial rehabilitation – day centres and clubhouses – and to explore if either appears better suited to support people in mental health recovery. The recovery focus is on opportunities for engaging in meaningful daily occupations, accessibility to social interaction and factors pertaining to perceived health and well-being. LÄS MER

3. 2. Cadmium Free Buffer Layers and the Influence of their Material Properties on the Performance of Cu(In,Ga)Se2 Solar Cells

   Författare :Adam Hultqvist; Charlotte Platzer-Björkman; Tobias Törndahl; Marika Edoff; Takashi Minemoto; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cu In; Ga Se2; Solar cells; Thin film; Buffer layer; Window layer; ZnO; Zn O; S ; Zn; Mg O; Zn-Sn-O; Semiconductor physics; Halvledarfysik; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

   Sammanfattning : CdS is conventionally used as a buffer layer in Cu(In,Ga)Se2, CIGS, solar cells. The aim of this thesis is to substitute CdS with cadmium-free, more transparent and environmentally benign alternative buffer layers and to analyze how the material properties of alternative layers affect the solar cell performance.

5. 4. The Role of Reactive Oxygen Species in Animal Models of Autoimmunity

   Författare :Malin Hultqvist; Immunologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mice; Phytol; ROS; NOX; NADPH; p47phox; Ncf1; EAE; inflammation; Arthritis; RA; MS; Rats; Autoimmunity;

   Sammanfattning : Reactive oxygen species (ROS) produced by the phagocyte NADPH oxidase complex are important in the killing of invading pathogens. Lately, a role of ROS has been suggested in regulation of the immune system. LÄS MER

7. 5. Elastohydrodynamically lubricated finite line contacts operating under transient conditions

   Författare :Tobias Hultqvist; Roland Larsson; Lars-Erik Stacke; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

   Sammanfattning : The effect of greenhouse gas emissions contributing to the global warming is today becoming an increasingly important problem worldwide and has led to increased efforts being made on improving tribological performance of interacting surfaces in mechanical systems. Due to increasingly stringent CO2regulations, a reduced fuel consumption has become a key area of interest for the automotive industry where low cost, low emission solutions are continuously developed and where low friction alternatives to machine elements currently in use are evaluated.
