  3. 12. A flexible resonance sensor system for detection of cancer tissue : evaluation on silicon

    Författare :Anders P. Åstrand; Britt Andersson; Ville Jalkanen; Olof A. Lindahl; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The most common form of cancer among men in Europe and the US is prostate cancer. When a radical prostatectomy has been found necessary, it is of interest to examine the prostate, as tumour tissue on the capsule might indicate that the cancer has metastased. This is commonly done by a microscope-based morphometric investigation. LÄS MER

  5. 14. Welding of Heavy Structures Subjected to Fatigue

    Författare :Erik Åstrand; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Weld quality; Fillet welds; Weld procedures; Fatigue; Welded applications.; GMAW;

    Sammanfattning : Welding is a key process for heavy steel structures, but it is also a weak link of the structure since fatigue fractures in welds are a common cause for failures. This thesis proposes several changes in order to improve the fatigue properties in a cost effective way. LÄS MER

  7. 15. Regulation of aortic wall mechanics and stress : An experimental study in man

    Författare :Håkan Åstrand; Toste Länne; Matts Karlsson; Martin Björck; Linköpings universitet; []
