  1. 1. Traumatic isolated rupture of the knee medial collateral ligament : diagnosis and long term effects

    Författare :Magnus Lundberg; Per Renström; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Isolated partial rupture of the knee medial collateral ligament (MCL) is the most common traumatic knee ligament injury. Owing to the good short- and medium-term functional results after conservative treatment, this injury has been regarded as harmless. LÄS MER

  3. 2. On the long-term behaviour of tension loaded piles in natural soft soils

    Författare :Jorge Yannie; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soft clay; piles; creep rupture; rate dependent; tension load; long-term; field test; numerical model; uplift; creep of piles; installation;

    Sammanfattning : The complexity and scale of new infrastructure projects have challenged the current geotechnical design practice. Urban areas are growing at a fast pace in the horizontal and vertical direction, with taller buildings and deeper underground constructions in already densely populated areas. LÄS MER

  4. 3. Long-term perspectives on musculoskeletal pain : Health care utilization and integration of behavioral medicine treatment into physical therapy

    Författare :Christina Emilson; Pernilla Åsenlöf; Ingrid Demmelmaier; Stefan Bergman; Ida Flink; Uppsala universitet; []
    Nyckelord :Chronic pain; health care utilization; behavioral medicine; stratified treatment; prognostic factors; physical therapy; primary care; Medicinsk vetenskap; Medical Science;

    Sammanfattning : There are currently no effective methods for treating and preventing chronic pain. The aim of this thesis was to study prognostic factors for health care utilization, and the long-term outcomes of tailored behavioral medicine treatment for patients with musculoskeletal pain.

  5. 4. Long-term properties of polyethylene films : efficiency of a natural antioxidant

    Författare :Clara Strandberg; Ann-Christine Albertsson; Jukka Seppälä; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer Technology; alfa-tocopherol; Polyethylene PE ; Thermal aging; Infrared Spectroscopy FT-IR ; Chemiluminescence CL ; Solid-phase microextraction SPME ; Chemistry; Kemi;

    Sammanfattning : There is a growing awareness of the risks of pollution in biological systems and one potential problem is the synthetic antioxidants, used for e.g. the stabilisation of polymeric materials. Natural antioxidants are an interesting alternative, if the high efficiency and thermal stability of the synthetic compounds can be reached. LÄS MER

  7. 5. Long-term Voltage Stability in Power Systems - Alleviating the Impact of Generator Current Limiters

    Författare :Stefan Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rotor thermal overloading; dynamic load modelling; voltage stability; field current limiter; active power rescheduling; overexcitation limiter; armature current limiter; long-term power system dynamic stability;

    Sammanfattning : The main issues in this dissertation are the behaviour of current limiters protecting synchronous generators, and the interactions that occur with other components in the power system during a voltage instability. The importance of these limiters for the voltage stability is shown both in the analysis of small models and in the simulations of larger networks. LÄS MER
