  1. 21. Improved PWB test methodologies

    Författare :Abdelghani Renbi; Erik Larsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Sammanfattning : Printed Wiring Board (PWB) and Printed Circuit Board Assembly (PCBA) testing aims to ensure an error free board after the etching and the assembly processes. After the etching process, several types of errors might occur such as opens and bridges, which are already, showstoppers in Direct Current (DC) applications. LÄS MER

  2. 22. Simulation of manufacturing sequences for verification of product properties

    Författare :Mats Werke; Torsten Kjellberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing engineering and work sciences; Produktion och arbetsvetenskap;

    Sammanfattning : The manufacturing sequence may to a large extent influence properties like residual stresses and hardness and, as a consequence, the fatigue life and shape accuracy of a component. By simulating the manufacturing sequence and extract important accumulated data, the possibilities of early analysis of a design concept of a component and optimisation of the complete manufacturing sequence may increase.

  3. 23. A strategy for ranking environmentally occuring chemicals

    Författare :Lennart Eriksson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; QSAR; hazard ranking; statistical design; multivariate modelling; halogenated aliphatics; PCA; PLS;

    Sammanfattning : A systematic methodology for quantitative structure-activity relationship (QSAR) development in environmental toxicology is provided. The methodology is summarized in a strategy with six sequential steps. LÄS MER

  4. 24. A kinetic study of metabolite transfer in coupled two-enzyme reactions

    Författare :Henrik Pettersson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Free diffusion; Enzyme kinetics; Channelling; Dehydrogenase; Fusion protein; Biochemistry; Proximity effect; metabolism; Biokemi;

    Sammanfattning : There are two fundamentally different ways by which a metabolite can be transferred between enzymes in metabolic pathways. If the two sequential enzymes cannot form a complex with each other, the metabolite must first be released from the producing enzyme to the reaction medium and then be transported to the consuming enzyme, via the reaction medium, by free diffusion.

  5. 25. Magnetic Resonance Imaging as a Screening Tool for Prostate Cancer

    Författare :Kimia Kohestani; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostate cancer; prostate-specific antigen; magnetic resonance imaging; screening; early detection;

    Sammanfattning : The overall aim of this thesis was to explore the role of Magnetic resonance imaging (MRI) of the prostate as an adjunct to the prostate-specific antigen (PSA)-test in screening for prostate cancer (PCa), focusing on the performance of MRI in detecting clinically significant PCa within the randomised controlled GÖTEBORG Prostate Cancer Screening 2 Trial. By inviting men 50–60 years of age to different screening strategies—PSA cut-off for biopsy 3. LÄS MER
