  1. 21. Deactivation of diesel oxidation catalysts

    Författare :Jonas Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accelerated aging: Diesel exhaust: Oxidation catalyst: Sulfur deactivation: Phosphorous poisoning: CO oxidation: Pt dispersion: Al2O3: Sintering: TEM: XPS;

    Sammanfattning : To meet the demand for heavy- and light-duty diesel vehicles on expansive markets while complying with current and future emission standards, it is necessary to reinsure the long-livety of the applied exhaust aftertreatment technology. Loss of catalytic performance may be associated with environmental as well as economical consequences. LÄS MER

  3. 22. On the treatment of tibial shaft fractures

    Författare :Abbas Karladani; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cast; Distraction; Dynamometry; Fracture; Limb lengthening; Nailing; Outcome; Psychometry; Shaft; Soft tissue; Tibial;

    Sammanfattning : The aim of this thesis was to evaluate those factors, which have predictive value for development of complications after tibial shaft fractures, and to evaluate the outcome of the available treatment methods for closed, as well as open tibial shaft fractures associated with extensive soft-tissue injury. To determine the factors, which influence healing speed, we reviewed 100 consecutive patients with 104 tibial shaft fractures tibial shaft fractures. LÄS MER

  4. 23. Standing in children with bilateral spastic cerebral palsy : aspects of muscle strength, vision and motor function

    Författare :Cecilia Lidbeck; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The movement and posture disorder of cerebral palsy (CP) is presumed to mainly be a consequence of the motor disorder, but accompanying disturbances with sensations and perception have also been suggested to influence motor function. The aim was to investigate factors influencing standing posture in children with bilateral spastic CP (BSCP) with varying standing abilities. LÄS MER

  5. 24. Machining Monitoring and Control : Based on Parametric Modelling

    Författare :Mats Bejhem; KTH; []
    Nyckelord :Machining Control; tool condition monitoring; in-process dynamic stability monitoring and control; optimisation of cutting conditions; MC; DSP; TCM; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : The objective of this work was the development of aMachining Control prototype system for turning, whichintegrates three fundamental aspects of Machining Controltechnology: Monitoring, Control and Optimisation. MachiningControl refers to the detection and automatic handling ofdisturbances in machining processes. LÄS MER

  7. 25. Long-term effects of growth hormone replacement in hypopituitary adults on body composition, bone mass and cardiovascular risk factors

    Författare :Mariam Elbornsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; growth hormone; growth hormone deficiency; growth hormone replacement; bone mineral density; body composition; muscle strength; elderly; cardiovascular risk factors; pituitary irradiation;

    Sammanfattning : Growth hormone (GH) deficient (GHD) adults have decreased bone mass and muscle strength, impaired body composition, disturbed serum lipid pattern and increased morbidity and mortality in cardiovascular and cerebrovascular diseases. GH replacement normalizes most of these aberrations within the first year of treatment. LÄS MER
