1. 11. Engineered Yeast as Biocatalyst for Stereoselective reductions of Dicarbonyl Compounds

   Författare :Ted Johanson; Teknisk mikrobiologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chiral; screening; process optimisation; metabolic engineering; dicarbonyl; biocatalysis; yeast; bioreduction; Biotechnology; Bioteknik;

   Sammanfattning : Chiral building blocks are needed in the chemical and pharmaceutical industries for the production of fine chemicals and pharmaceuticals. The utilisation of microorganisms and enzymes to perform stereoselective reductions of carbonyl compounds is an efficient and widely applied method for the generation of chiral molecules. LÄS MER

3. 12. Future stratospheric ozone depletion will affect a subarctic dwarf shrub ecosystem

   Författare :Ulf Johanson; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Vaccinium; UVB; subarctic; shoot growth; ozone depletion; leaf thickness; irradiation system; heath ecosystem; Empetrum; dwarf shrubs; Calamagrostis; decomposition; Physiological biophysics; Växtfysiologi;

   Sammanfattning : The stratospheric ozone depletion and the concomitant increase in ultraviolet-B (UV-B, 280-320 nm) radiation is of global concern due to the effects of UV-B on living organisms. To investigate the effects of increased levels of UV-B, a field irradiation system was established at a subarctic dwarf shrub heath in Northern Sweden (68 °N). LÄS MER

5. 14. Communicating about health in health care : Perspectives on life style and post-operative complications

   Författare :Marita Johanson; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; patient-physician communication; institutional discourse; patients and health care perspectives; postoperative complications; life style; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

   Sammanfattning : This study, which is exploratory in nature, has been conducted with the aim of uncovering patients' participation and co-operation in modern health care and analysing what the conditions of this co-operation look like. Another aim has been to enhance knowledge about institutional discourse on a general level as well as about dialogues between patients and physicians concerning life style issues at a more specific level.
