    Sammanfattning : Efficiency improvement in turbomachines is an important aspect in reducing the use of fossil-based fuel and thereby reducing carbon dioxide emissions in order to achieve a sustainable future. Gas turbines are mainly fossil-based turbomachines powering aviation and land-based power plants. LÄS MER

  4. 3. Geotechnical Aspects of Buildings on Expansive Soils in Kibaha, Tanzania

    Författare :Charles Lucian; Staffan Hintze; Sven Knutsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Expansive soils; soil properties; potential swell; smectite montmorillonite ; multivariate statistics; geo-statistics; spatial variability; lightweight structures; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning :  The focus of this study is on potential damages to buildings resulting from expansive soils in Tanzania, particularly clay soils in Kibaha. For the fact that most of the affected structures are founded on expansive soils, a clear understanding of the behaviour of soils and their interaction with structures has been of interest to the study in order to evaluate properly the source of the problem.

  5. 4. Investigation of boundary layer transition for transonic flow over compressor and turbine airfoils

    Författare :Susanne Svensdotter; KTH; []
    Nyckelord :;

    Sammanfattning : This thesis considers the laminar-turbulent transition overcompressor and turbine airfoils at high subsonic and transonicflow conditions.First, experiments on the laminar-turbulent transition on anisolated airfoil in high subsonic and transonic flow wereperformed. LÄS MER

  7. 5. Surgically Treated Intracerebral Haemorrhage : Pathophysiology and Clinical Aspects

    Författare :Lovisa Tobieson; Niklas Marklund; Bijar Ghafouri; Sandro Rossitti; Peter Zsigmond; Jan Hillman; Mikael Svensson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Mortality and morbidity of intracerebral haemorrhage (ICH) is excessively high, and the case fatality rate has not improved in the last decades. Although surgery for ICH can be life-saving, no positive effect on functional outcome has been found in large cohorts of ICH patients. LÄS MER
