  3. 7. Season of birth in suicidology : neurobiological and epidemiological studies

    Författare :Jayanti Chotai; Hans Ågren; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; season of birth; CSF monoamine metabolites; suicide method; borderline;

    Sammanfattning : Background: Several neuropsychiatrie disorders have shown season of birth associations. Low cerebrospinal fluid (CSF) levels of the serotonin metabolite 5-HIAA and the dopamine metabolite HVA have been associated with suicidal behaviour, impulsivity, and aggression. LÄS MER

  4. 8. Analytical Aerodynamic Simulation Tools for Vertical Axis Wind Turbines

    Författare :Paul Deglaire; Hans Bernhoff; Olov Ågren; Staffan Lundstrom; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vertical axis turbine; vortex flows; conformal mapping; analytical aerodynamics; potential flows; fast multipole methods; Fluid mechanics; Strömningsmekanik; Teknisk fysik; Engineering Science;

    Sammanfattning : Wind power is a renewable energy source that is today the fastest growing solution to reduce CO2 emissions in the electric energy mix. Upwind horizontal axis wind turbine with three blades has been the preferred technical choice for more than two decades. This horizontal axis concept is today widely leading the market. LÄS MER

  5. 9. Posttraumatic Stress Disorder (PTSD) in the General Population

    Författare :Örjan Frans; Mats Fredrikson; Hans Ågren; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; posttraumatic stress disorder; trauma; epidemiology; general population; prevalence; traffic road accidents; DSM-structure; positron emission tomography; regional cerebral blood flow; symptom provocation; selective serotonin reuptake inhibitor; Psykologi; Psychology; Psykologi; klinisk psykologi; Clinical Psychology;

    Sammanfattning : This thesis explored the epidemiology of Posttraumatic Stress Disorder (PTSD) and different aspects of the disorder. Firstly, we investigated the lifetime prevalence of traumatic experiences and PTSD in the general adult population in Sweden and evaluated the impact of different trauma types, trauma frequency, and perceived distress.

  7. 10. Theoretical studies of EPR parameters of spin-labels incomplex environments

    Författare :Bogdan Frecus; Hans Ågren; Chiara Cappelli; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; EPR; DFT; spin-labels; QM MM; Breit-Pauli Hamiltonian;

    Sammanfattning : This thesis encloses quantum chemical calculations performed in the framework of density functional response theory for evaluating electron paramagnetic resonance (EPR) spin Hamiltonian parameters of various spin-labels in different environments. These parameters are the well known electronic g-tensor and the nitrogen hyperfine coupling constants, which are extensively explored in this work for various systems. LÄS MER
