  1. 1. Hydromechanical Behaviour of Fractures Close to Tunnels in Crystalline Rock

    Författare :Johan Thörn; Chalmers University of Technology; []
    Nyckelord :Fracture stiffness; Fracture geometry; Laboratory experiments; Äspö HRL; Rock stress; In situ; Deformation measurement; Hallandsås; Hydromechanical coupling; Geological history;

    Sammanfattning : The deformation and stiffness properties of rock fractures are important measurable parameters when describing their hydromechanical behaviour. Deformation refers to aperture change. Stiffness refers to the amount of deformation per stress change to which a fracture is subjected. LÄS MER

  2. 2. The Impact of Fracture Geometry on the Hydromechanical Behaviour of Crystalline Rock

    Författare :Johan Thörn; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Laboratory experiments; Fracture aperture; In situ experiments; Conceptual model; Äspö HRL; Fracture geometry; Stereo photogrammetry; Hydromechanical coupling; Fracture normal stiffness;

    Sammanfattning : Effective construction of tunnels in fractured crystalline rock requires a unified approach for handling rock mechanics and hydrogeological issues. Traditionally, rock mechanics and hydrogeology not only use different nomenclature, they also measure parameters such as e.g. aperture differently. LÄS MER

  3. 3. Minimal Residual Disease Assessment in Childhood Acute Lymphoblastic Leukemia

    Författare :Ingrid Thörn; Christer Sundström; Richard Rosenquist; Gisela Barbany; Johan Botling; Kjeld Schmiegelow; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Childhood acute lymphoblastic leukemia; minimal residual disease; IG TCR gene rearrangements; BCR-ABL1 fusion gene transcripts; real-time quantitative PCR; multicolor flow cytometry; Pathology; Patologi; Pathology; patologi;

    Sammanfattning : Traditionally, response to treatment in hematological malignancies is evaluated by light microscopy of bone marrow (BM) smears, but due to more effective therapies more sensitive methods are needed. Today, detection of minimal residual disease (MRD) using immunological and molecular techniques can be 100 times more sensitive than morphology. LÄS MER
