  1. 1. Predicting prostate cancer : on the use of biomarkers in prostate cancer diagnostics

    Författare :Tobias Nordström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Aims: The aims of this thesis work were to answer the following questions. Paper I: How prevalent is testing and retesting with prostate-specific antigen (PSA)?; Paper II: Is a genetic score based on single-nucleotide polymorphisms (SNPs) informative regarding the risk of prostate cancer (PCa) in men with low PSA?; Paper III: Are the commercially available tests Prostate Health Index (PHI) and the four-kallikrein panel comparable in aiding biopsy decisions?; Paper IV: Do commonly used medications affect PSA and the risk of PCa? Methods: In Paper I and Paper IV, the population-based PSA cohort STHLM0 was used together with registry-based data. LÄS MER

  3. 2. Concrete as a multi-physical material with applications to hydro power facilities

    Författare :Tobias Gasch; Anders Ansell; Richard Malm; Erik Nordström; Mats Emborg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : During its lifetime, a concrete structure is subjected to many different actions, ranging from mechanical loads to environmental actions. To accurately predict its integrity from casting and throughout its service life, a modelling strategy is required that considers mechanical loading but also implicitly accounts for physical effects such as temperature and moisture variations.
