  1. 6. Transition Metal-Catalyzed Redox Reactions : A Journey from Homogeneous Ruthenium to Heterogeneous Palladium Catalysis

    Författare :Oscar Verho; Jan-Erling Bäckvall; Manfred Reetz; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organisk kemi; Organic Chemistry;

    Sammanfattning : The first part of the thesis covers the development and utilization of electronically modified (pentaarylcyclopentadienyl)Ru-complexes in the racemization of secondary alcohols. This study revealed that the electronic properties of the substrate were the main factors dictating whether β-hydride elimination or hydride re-addition becomes the rate-determining step of the racemization process.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic load; initial response; shear failure; shear capacity; numerical simulations; bond; shear span; support reactions; Dynamisk last; initial respons; skjuvbrott; skjuvkapacitet; numeriska simuleringar; förankring; skjuvspännvidd; upplagsreaktioner; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : Concrete structural elements subjected to severe dynamic loads such as explosions at close range may cause shear failures. In the Oklahoma City bombing in 1995 two concrete columns on the ground level were reported to have failed in shear. LÄS MER

  4. 8. Traumatic Exposure, Bereavement and Recovery among Survivors and Close Relatives after Disasters

    Författare :Kerstin Bergh Johannesson; Tom Lundin; Per-Olof Michel; Christina M Hultman; Are Holen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Natural disaster; traumatic exposure; life threat; traumatic bereavement; psychological distress; posttraumatic stress reactions; PTSD; general mental health; suicidal ideation; complicated grief; social support; resilience; recovery; Psychiatry; Psykiatri; Psychology; Psykologi; Psychiatry; Psykiatri;

    Sammanfattning : International studies of disasters indicate the risk for developing posttraumatic stress reactions among survivors is high. Modern life implicates increased traveling. During the last decades a large number of Swedish citizens were confronted with disasters taking place outside of their country. LÄS MER

  5. 9. Investigations of Slag Properties and Reactions

    Författare :Mikael Persson; Seshadri Seetharaman; Masanori Iwase; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Sammanfattning : The present dissertation describes the efforts directed towards the development of computational tools to support process modeling. This work is also a further development of the Thermoslag® software developed in the Division of Materials Process Science, KTH. LÄS MER

  7. 10. Self-management support to handle everyday life with Parkinson´s disease

    Författare :Carina Hellqvist; Carina Berterö; Peter Hagell; Märtha Sund-Levander; Nil Dizdar Segrell; Stefan Sävenstedt; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parkinson’s disease; self-management; everyday life; self-care support; care partners; self-management intervention;

    Sammanfattning : Background: Being diagnosed with Parkinson´s disease (PD) is a life-altering experience. The long-term condition requires continuous adjustments to the everyday life not only of the person affected, but also for care partners. LÄS MER
