  1. 1. Skalningseffekter av medelstora pölbränder i syrereducerad miljö

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Tim Hemel; Philip Frenander; [2024]
    Nyckelord :Sökord: syrereducerad atmosfär; medelstora pölbränder; skalningseffekter. Key words: hypoxic air; oxygen reduced atmosphere; medium pool fire; scaling effects; LOC; yields.; Technology and Engineering;

    Sammanfattning : This bachelor's thesis focuses on how scaling the pool diameter affects flammable liquids in an oxygen reduction system (ORS). This topic in the study of pool fire behavior in hypoxic air has been only lightly discussed in previous literature. Therefore, the goal of this thesis work is to further broaden the understanding of hypoxic air. LÄS MER

  3. 2. A REVIEW OF PHYSICAL ACTIVITY’S EFFECT ON MOOD Through the Lens of the HPA Axis

    Kandidat-uppsats, Institutionen för tillämpad informationsteknologi

    Författare :Susanna Karlkvist; Anton Wickberg; [2023-02-01]
    Nyckelord :Mood; Physical activity; HPA axis; The cross-stressor adaptation hypothesis; CRH; Exercise; Cortisol; Cognition;

    Sammanfattning : Engagement in physical activity (PA) has been said to trigger a chain reaction of events which can alter our mood state. One recently implicated component is the hypothalamic-pituitary-adrenal (HPA) axis, involved in the reaction to physical and psychological stress-ors. LÄS MER

  5. 4. Mapping of Process Hazard Analyses in Swedish Process Industries and How the Work Can Be Improved

    Master-uppsats, Lunds universitet/Riskhantering (CI)

    Författare :Isabella Bergström; [2022]
    Nyckelord :Risk management; Qualitative risk assessment; PHA; Process safety; Seveso directive; Technology and Engineering;

    Sammanfattning : This study aims to map how Swedish process industries use qualitative risk analyses, such as process hazard analyses (PHA), to assess risks. Beyond the Seveso legislation, which requires all facilities classified as upper tier to perform a safety report each fifth years, there are no Swedish legislation or regulations regarding how and when PHAs should be executed.
