  3. 2. Numerical Analysis of Partial Admission in Axial Turbines

    Författare :Narmin Baagherzadeh Hushmandi; Torsten H. Fransson; Liping Xu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical energy engineering; Mekanisk energiteknik;

    Sammanfattning : HTML clipboard Numerical analysis of partial admission in axial turbines is performed in this work. Geometrical details of an existing two stage turbine facility with low reaction blades is used for this purpose. For validation of the numerical results, experimental measurements of one partial admission configuration at design point was used. LÄS MER

  4. 3. Effects of higher education and the role of admission selection

    Sammanfattning : Study I Using Admission Selection Rules to Estimate the University Earnings Premium - A Regression-Discontinuity DesignThis study estimates the earnings premiums for university admission and graduation, using unique data from the admission selection process. Applicants and non-applicants for university in Sweden in 1982 are studied in terms of earnings in 1996. LÄS MER

  5. 4. Carbon dioxide, oxygen, and serum biomarkers after out-of-hospital cardiac arrest

    Författare :Florian Ebner; Helsingborg Kliniska Vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Carbon dioxide; oxygen; serum biomarkers; out-of-hospital cardiac arrest;

    Sammanfattning : Cardiac arrest is the aprupt loss of cardiac function and circulation, follwed by the loss of consciousness and breathing. Most patients succumb before admission to hospital and survivors frequently suffer from anoxic-ischemic brain injury. The number of patients who survive with good neurological outcome, is low.

  7. 5. On vocational rehabilitation in northern Sweden : with focus on life satisfaction and outcome prediction

    Författare :Michael Eklund; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Work; Vocational rehabilitation; Impairment; Disability; Outcome; Return to work; Earnings; Psycho-social aspects; Life Satisfaction; Happiness; Chronic pain;

    Sammanfattning : A consecutive series of 149 subjects with complete or partial vocational disability due to somatic ill-health were investigated at admission for vocational rehabilitation and two years later. Subjects filled in checklists which encompassed 5 socio-demographic, 5 psycho-social and 9 life satisfaction items. LÄS MER
