  1. 21. Simplifying medical abortion services in primary care settings in India

    Författare :Kirti Iyengar; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Even in countries where abortion is legal, many women suffer mortality and morbidity from unsafe abortion. When faced with an unwanted pregnancy, women encounter many social, geographical, and health system level barriers in accessing safe abortion. LÄS MER

  3. 22. Improving maintenance treatment of heroin addiction : the role of buprenorphine

    Författare :Karl Johan Kakko; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Heroin addiction is a condition with high morbidity and mortality. The discovery of Methadone Maintenance Treatment (MMT) by Dole and co-workers 1964 represented the first major advance in the treatment of this condition. Through the work of Gunne et al in Uppsala, MMT was implemented in Sweden already in 1966. LÄS MER

  4. 23. Probabilistic System Effects in Timber Structures

    Författare :Martin Hansson; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; Anläggningsteknik; Construction technology; first order reliability method; Monte Carlo simulation; system effect; sheathed parallel member system; structural timber; roof truss;

    Sammanfattning : The main purpose of the performed research presented in this thesis is to increase the understanding of the effect of variability of strength properties on the reliability of timber structural systems. Compared to other structural materials such as steel and concrete, structural timber has a considerably higher variability of strength both within and between members. LÄS MER

  5. 24. Glulam timber arches : strength of splices and reliability- based optimisation

    Författare :Nils Olsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Sammanfattning : Arch structures are very sensitive to changes in the distribution of the load as well as to changes in their shape. A slight change in the load distribution may imply internal forces for which the arch is not designed. LÄS MER

  7. 25. Coil Design and Related Studies for the Fusion-Fission Reactor Concept SFLM Hybrid

    Författare :Anders Hagnestål; Olov Ågren; Vladimir Moiseenko; Ladislav Bardos; Jan Scheffel; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fusion; Fission; Hybrid reactor; Actinides; Mirror Machine; Quadrupolar mirror; Coils; Fysik; Physics;

    Sammanfattning : A fusion-fission (hybrid) reactor is a combination of a fusion device and a subcritical fission reactor, where the fusion device acts as a neutron source and the power is mainly produced in the fission core. Hybrid reactors may be suitable for transmutation of transuranic isotopes in the spent nuclear fuel, due to the safety margin on criticality imposed by the subcritical fission core. LÄS MER
