3. 2. Metabolism of free and complexed prostate - specific antigen and their utility for diagnosis and prognosis of prostate cancer

   Författare :Thomas Björk; Malmö Urologisk cancerforskning; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; benign prostatic hyperplasia; alpha-1-antichymotrypsin; PSA; prostate cancer; prostate-specific antigen; Urology; nephrology; Urologi; nefrologi;

   Sammanfattning : Prostate-specific antigen (PSA) is a glycoprotein produced by the prostate gland. It occurs in several molecular forms in the blood and assays have been developed to measure free PSA and PSA in complex with alpha-1-antichymotrypsin (PSA-ACT). LÄS MER

4. 3. Tribological aspects of aluminium extrusion dies

   Författare :Thomas Björk; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Extrusion; Die; Wear; Tool; Friction; Simulation; Bearing; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

   Sammanfattning : Extrusion is a common method to manufacture long products of aluminium, such as beams, rods and tubes. The aim of this thesis was to improve the material in the die bearing surface, and thereby the service life of extrusion dies through wear studies of actual dies, and experimental simulations.

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

   Författare :Thomas Thorsell; Folke Björk; Mark Bomberg; Targo Kalamees; KTH; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER
