    Sammanfattning : The increasing drive for sustainable and eco-friendly transportation has made the electrification of cars a top priority in the energy and transportation sectors. Ensuring the safety of electrical vehicle (EV) batteries is of the utmost importance. LÄS MER

  4. 23. Flame Extensions Under Ceilings

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Martin Sturdy; [2023]
    Nyckelord :Flame length; curved ceiling; Technology and Engineering;

    Sammanfattning : In this Master thesis project the factors affecting flame extension under flat and curved ceilings have been investigated. An experimental campaign was carried out in Lund University’s Fire Lab using a propane gas burner and heptane pool fire in different positions and heat release rates within the setups. LÄS MER

  5. 24. CAMBODIAN-THAI BORDER CONFLICT; A critical case study and grassroots stakeholders’ perspectives on the 2008 Preah Vihear Temple (PVT)

    Master-uppsats, Göteborgs universitet/Institutionen för globala studier

    Författare :Kunty Touch; [2022-11-08]
    Nyckelord :Preah Vihear temple; Cambodia; Thailand; conflict; grassroots stakeholders; peace; bottom-up peacebuilding;

    Sammanfattning : The revival of the Preah Vihear conflict resumed again in 2008 not focusing on the architectural structure of the temple but over the unclearly claimed the temple’s vicinity of 4.6km2 after the UNESCO registered the temple as the World Heritage. LÄS MER

  7. 25. A Comparative Study of Fires in Corners and Along Walls

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Josef Utterfors; Adam Tegenfeldt; [2022]
    Nyckelord :Fire; wall; corner; hot gas layer; flame height; plume temperature; Technology and Engineering;

    Sammanfattning : The topic of fires in corners and along walls has been studied previously, however, two different studies conducted in 1987 and 2018 respectively, produced conflicting results regarding plume temperature for fires along walls, as well as hot gas layer temperature for both fires in corners and along walls. This thesis seeks to add data and clarification about fires in corners and along walls. LÄS MER
