    Sammanfattning : This thesis work deals with the volume changes during the solidification of cast irons and peritectic steels. The volume changes in casting metals are related to the expansion and/or contraction of the molten metal during solidification. Often, different types of shrinkage, namely macro- and micro-shrinkage, affect the casting quality. LÄS MER

  4. 3. Minimally invasive aortic valve replacement

    Författare :Magnus Dalén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Minimally invasive aortic valve replacement (AVR) through a ministernotomy has been developed as an alternative approach to conventional full sternotomy AVR. During recent years, sutureless aortic bioprostheses were introduced with the aim to facilitate implantation, especially in minimally invasive procedures. LÄS MER

  5. 4. Venous thromboembolism in women : risk factors and long term follow-up

    Författare :Kristina Sonnevi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Venous thromboembolism (VTE) is a common and potentially life threatening disease. Women have different risk factors than men at both first and recurrent VTE. The aim of this thesis was to further identify and explore risk factors for VTE in young and middle aged women. LÄS MER
