6. 4. Advances in Thermal Insulation : Vacuum Insulation Panels and Thermal Efficiency to Reduce Energy Usage in Buildings

   Author : Thomas Thorsell; Folke Björk; Mark Bomberg; Targo Kalamees; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vacuum insulation panels; VIP; serpentine edge; thermal bridge; composite film; gas diffusion; defect dominated; holistic approach; building enclosure; integrated testing and modeling; energy equivalent; field performance; air flow; thermal insulation efficiency;

   Abstract : We are coming to realize that there is an urgent need to reduce energy usage in buildings and it has to be done in a sustainable way. This thesis focuses on the performance of the building envelope; more precisely thermal performance of walls and super insulation material in the form of vacuum insulation. READ MORE

7. 5. Aspects of Disability in Rheumatoid Arthritis : a five-year follow-up in the Swedish TIRA project

   Author : Mathilda Björk; Björn Gerdle; Ingrid Thyberg; Thomas Skogh; Klas Rikner; Karin Harms-Ringdahl; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rheumatoid arthritis RA ; disability; hand function; pain intensity; ADL; sick leave; prediction; Rheumatology; Reumatologi;

   Abstract : Rheumatoid arthritis (RA) is a progressive disease, often leading to disability. Because the disease course develops rapidly during the first years after diagnosis, more knowledge is needed about the early disease course to minimize later disability. READ MORE
