  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

    Sammanfattning : Cancer is the collective name for more than 200 types of diseases that annually causes the death of 8.8 million people, cancer in the head and neck (H&N) accounts for 330.000 of these. It has been shown that hypoxic tumors are more resistant to treatment than well oxygenated tumors. LÄS MER

  5. 4. Brandfarliga vätskor i syrereducerade miljöer

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Carl Nilsson; Max Hersner; [2021]
    Nyckelord :Hypoxic air; Brandfarliga vätskor; Reduced oxygen; Limiting oxygen; Cone calorimeter; Flammable liquids; ORS; LOC; CACC; Heat release rate; Mass loss rate; Technology and Engineering;

    Sammanfattning : Unmanned warehouses are increasing in number as workers are replaced by automated robotic systems. This type of facility, among others, is well suited for an oxygen reduction system for fire protection. By lowering the oxygen concentration, the risk of fire propagation is reduced and might be hindered altogether. LÄS MER

  7. 5. Spatiotemporal responses of wheat and pea roots to fluctuations in soil physical conditions

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Hanna Sjulgård; [2020]
    Nyckelord :rhizobox; time-lapse imaging; growth rate; diameter;

    Sammanfattning : Penetration resistance and the oxygen level vary in the soil, and a root will face fluctuations in these physical properties during development. The aim of this study was to understand how pea (Pisum sativum L.) and wheat (Triticum aestivum L. LÄS MER
