  1. 21. Effects of fuel and weather conditions on forest fire behaviour in Southern Sweden in oak dominated forests

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Olga Teresa Wepryk; [2023]
    Nyckelord :forest fire; forest fuel; fire weather; ignition experiments; prescribed burning;

    Sammanfattning : Fire activity is influenced by weather and climate, fuels, ignition agents, and human activities. Fire suppression policy in Sweden resulted in a gradual decrease in the annually burnt areas, changes in fuel loads and a decline in species diversity. LÄS MER

  3. 22. Detectability of insects in Malaise traps : assessing insect detectability in Malaise traps through High-Resolution Sampling, and development of a novel marking technique

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Viktor Gårdman; [2023]
    Nyckelord :Malaise trap; activity; movement; weather; mark-recapture; detectability; insects;

    Sammanfattning : Malaise traps are extensively used in insect surveys and studies, yet the detectability of insects in relation to the traps remain unknown. Detectability is the odds that a taxon ends up in a trap, given that the taxon is present in the area around the trap. LÄS MER

  4. 23. Fuktsäkerhet vid byggnation av limträstomme under väderskydd : En undersökning hur fuktförhållandet i limträ påverkas vid nyttjande av väderskydd

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Joakim Hagelin; [2023]
    Nyckelord :Fuktsäkerhet; limträstomme; väderskydd;

    Sammanfattning : Cirka 60 000 bostäder skall byggas varje år under en tio årsperiod mellan 2021–2030. Samtidigt står byggbranschen för cirka 21% av Sveriges totala växthusutsläpp. Detta parallellt med att Sverige år 2045 ska vara ett land med nettonollutsläpp av växthusgaser till atmosfären. LÄS MER

  5. 24. How do fires affect the railway? - A Swedish study on what factors influence fire risk and how it affects railway traffic.

    Uppsats för yrkesexamina på grundnivå, Lunds universitet/Trafik och väg

    Författare :Jonatan Gustafsson; [2023]
    Nyckelord :Train; railway; fire; forest fires; delays; weather; Sweden.; Technology and Engineering;

    Sammanfattning : Forest fires can start in a variety of ways. "Fires started deliberately" and "fires started by sparks generated from a train braking" were two of the most common causes of fires between 2010 and 2020. Train braking accounted for 1.1% of all fires, whereas fires created by unknown reasons accounted for 43% of all fires. LÄS MER

  7. 25. Permeation studies of Niacinamide and its effect on human skin

    Master-uppsats, Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV)

    Författare :Andebrhan Fsahaye; [2023]
    Nyckelord :niacinamide; permeation; human skin; impedance; hydration;

    Sammanfattning :  Background: Niacinamide (NIA) is one of the most commonly used cosmetic ingredients. It belongs to the vitamin-B3 family and has extensive dermatological therapeutic benefits. NIA has been proven to be a useful skincare product in serving as anti-acne agent, preventing skin hyperpigmentation, removal of wrinkles from the face etc. LÄS MER
