  4. 13. Functional outcome and experiences concerning daily life after malunion of the distal radius and corrective osteotomy

    Författare :Ingrid Andreasson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Distal radius fracture; Malunion; Corrective osteotomy; Functional outcome; Activities of daily life; First post-operative year; Long-term;

    Sammanfattning : BACKGROUND. Distal radius fractures are common injuries that occur at all ages. The commonest complication is that the fracture heals in malunion. This can negatively affect function and the ability to perform activities. LÄS MER

  5. 14. Strategies to Mitigate the Degradation of Stainless-Steel Interconnects Used in Solid Oxide Fuel Cells

    Författare :Claudia Goebel; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dual Atmosphere; Interconnect; Deformation; Long-term; Solid Oxide Fuel Cell; Hydrogen; Corrosion; Cr Evaporation; Area Specific Resistance;

    Sammanfattning : Interconnects are a vital part of solid oxide fuel cells (SOFC), where they electrically connect individual cells to form a fuel cell stack. They are a main contributor to the overall stack cost and the limited life-time of fuel cells, and, therefore, improvements carried out on the interconnect level could further the commercialization of SOFCs.
