1. 11. The conserved methionines in the chloroplast small heat shock protein - Role in chaperone-substrate interactions and effects of methionine sulfoxidation on chaperone activity

   Författare :Niklas Gustavsson; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Biochemistry; oxidative stress; thermostability; temperature stress; stress tolerance; sHsp; protein aggregation; molecular chaperone; Heat stress; methionine sulfoxidation; Biokemi; metabolism; Plant biochemistry; Växtbiokemi;

   Sammanfattning : The chloroplast-localized small heat shock protein (sHsp) Hsp21 belongs to the family of alpha-crystallin like sHsps which form large oligomeric structures and protect partly unfolded aggregation-prone proteins against aggregation. The main focus for this thesis has been on the highly conserved methionines in Hsp21. LÄS MER

3. 12. Microstructure in SOFC: electrochemical simulations and experiments

   Författare :Xiaoqiang Zhang; Värmeöverföring; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid oxide fuel cell; Electrochemical impedance spectroscopy; 3D reconstruction; Tortuosity; Electrochemical kinetics; Multiphysics; Thermal stress;

   Sammanfattning : Solid oxide fuel cells (SOFCs) are highly efficient and environmentally friendly power sources that convert chemical energy directly into electricity and heat, without the need for combustion. Despite their many benefits, the performance and durability of SOFCs heavily depend on the quality of their porous anode and cathode components. LÄS MER

4. 13. Prestress in Nature and Technics

   Författare :Alexander Sehlström; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Geometrical stiffness; Prestress; Form finding; Architecture; Structural design; Stress pattern; Engineering; Conceptual design;

   Sammanfattning : To direct the forces of nature is a central task in the creation of spaces and load-carrying structures for architecture. This research investigates how prestress can be used as a design tool for the creation of material efficient and well-functioning structures, and in early design stages contribute to sustainable, functional and beautiful architecture.

5. 14. Alcohol Use and Stress in University Freshmen - A Comparative Intervention Study of Two Universities

   Författare :Claes Andersson; Kliniskt Centrum för Hälsofrämjande Vård; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; university dropout; stress measurement; comparative design; intervention; stress; university freshmen students; alcohol;

   Sammanfattning : Starting university is associated with major academic, personal and social opportunities. For many people, university entrance is also associated with increased stress and alcohol consumption. LÄS MER

7. 15. Cognitive Behavioral Stress Management Training for Nursing Students

   Författare :Ulrik Terp; Fredrik Hjärthag; Birgitta Bisholt; Petter Gustavsson; Karlstads universitet; []
