  1. 1. Ultrasonic Methods for 2D Arterial Wall Movement Measurements

    Författare :Magnus Cinthio; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tissue Doppler imaging; Cardiovascular system; Diagnostik; Diagnostics; Kardiovaskulära systemet; arteries; ultrasound; shear stress; axial movement; radial movement; Arterial distension; Arterial lumen diameter; PWV; Arterial longitudinal movement; pulse-wave velocity;

    Sammanfattning : Cardiovascular diseases constitute the major cause of morbidity and mortality in the Western World. To increase our knowledge of cardiovascular diseases, it is important to find methods, preferably non-invasive ones, to study very early manifestations of vascular disease. LÄS MER

  3. 2. Biomechanical methods and error analysis related to chronic musculoskeletal pain

    Författare :Fredrik Öhberg; Mats Djupsjöbacka; Åke Öberg; Högskolan i Gävle; []

    Sammanfattning : Background Spinal pain is one of humanity’s most frequent complaints with high costs for the individual and society, and is commonly related to spinal disorders. There are many origins behind these disorders e.g., trauma, disc hernia or of other organic origins. LÄS MER

  4. 3. Longitudinal Common Carotid Artery Wall Motion - mechanistic, prognostic and translational studies

    Författare :Sara Svedlund; Göteborgs universitet; []
    Nyckelord :carotid artery; longitudinal wall motion; ultrasound; velocity vector imaging; risk factor;

    Sammanfattning : The longitudinal arterial movement of the common carotid artery (CCA) has been less investigated during the past compared to the radial movement. This is probably due to lack of an adequate measuring method. Velocity vector ultrasound imaging (VVI) now enables assessment of the longitudinal movement. LÄS MER

  5. 4. Arthroplasty in Elbow Fracture Treatment

    Författare :Jens Nestorson; Lars Adolfsson; Carl Ekholm; Ola Wahlström; Simon Lambert; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Open reduction and internal fixation is the treatment of choice for distal humeral fractures. Stable fixation is required to allow early mobilisation and to reduce the risk of poor functional results. In an elderly patient with osteoporotic bone and with a comminuted intra-articular fracture stable internal fixation can be difficult to achieve. LÄS MER

  7. 5. Weichselian glaciations in the middle Notec River region, northwest Poland

    Författare :Gert Pettersson; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quaternary Geology; Kvartärgeologi; Geology; Geologi; Vistulian; Weichselian; Lithostratigraphy; Poland; Chodziez; Clast lithology; Clast fabrics; Deglaciation; Ice stream; Sedimentology; Sedimentologi; geomorphology; klimatologi; geomorfologi; climatology;

    Sammanfattning : This thesis presents results of studies on the ice flow pattern and ice movement mechanism during the Weichselian glaciations in the middle Notec River area, NW Poland. A new lithostratigraphy of the study area has been established, based on correlation of stratigraphical position, clast lithology, fabrics and grain size composition of till units. LÄS MER
