  1. 6. Domestication and early experiences in chickens : Behavior, stress and gene expression

    Författare :Pia Katrine Løtvedt; Per Jensen; Jordi Altimiras; Emma Brunberg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : A number of animal species have undergone domestication, the process of becoming adapted to living in captivity and in proximity to humans. Common for these species is that they have all developed certain traits, including changes to coat color, body size and level of fearfulness. This has been termed the domestic phenotype. LÄS MER

  3. 7. Surgical Stress in Rats : The Impact of Buprenorphine on Postoperative Recovery

    Författare :Renée Sundbom; Klas Abelson; Kristina Dahlborn; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgical stress; Corticosterone; Buprenorphine; Analgesia; Rats.; Försöksdjursvetenskap - Jämförande medicin; Comparative Medicine;

    Sammanfattning : During surgery, both anesthesia and tissue damage cause physiological stress responses in the body. The hypothalamic-pituitary-adrenal (HPA) axis is activated with increased levels of glucocorticoids. LÄS MER

  4. 8. Mechanical Behavior of Tailings : Laboratory Tests from a Swedish Tailings Dam

    Författare :Riaz Bhanbhro; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tailings dams; Tailings; Mechanical Behavior; Oedometer; Direct Shear; Triaxial; Shear strength; Soil Mechanics; Geoteknik;

    Sammanfattning : Tailings is leftover material from mining industry and is produced in huge quantities approximately 70-99% of the ore production.  Tailings material is stored as impoundments by constructing tailings dams which are often constructed with tailings material itself. LÄS MER

  5. 9. Childhood bereavement, stress resilience, and cancer risk : an integrated register-based approach

    Författare :Beatrice Kennedy; Katja Fall; Fang Fang; Unnur Valdimarsdottír; Scott Montgomery; Meena Kumari; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; alcohol; bereavement; cancer; drug use; epidemiology; health behaviour; psychological resilience; smoking; stress;

    Sammanfattning : Accumulating evidence suggests that psychosocial stress and susceptibility to stressful exposures – stress resilience – influence the risk of various health outcomes, but the potential link with cancer occurrence is unclear. The aims of this thesis were to test if loss of a close relative, a marker of severe psychological stress, and stress resilience measured during late adolescence are associated with cancer risk later in life, as well as to explore potential underlying mechanisms.

  7. 10. Modeling Driver Behavior : A Control Theory Based Approach

    Författare :Katja Vogel; Lars Åberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The aim of the project, which led to this thesis, was to suggest a micro-level driver behavior model, which would allow estimating the effects of safety measures on road traffic safety. The empirical research on driver behavior should be conducted in urban areas, because they are much less explored than rural areas, even though most non-fatal accidents occur in urban areas. LÄS MER
