  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. Riparian plant biodiversity and community composition of ditches and straightened streams : identifying key environmental drivers in a boreal forest setting

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Rasmus Staaf; [2024]
    Nyckelord :artificial waterways; riparian zone; novel ecosystems; ; forestry; ditch network maintenance; species richness; hill-diversity; drainage ditches; coarse woody debris; ditch cleaning; ecology;

    Sammanfattning : Modified ecosystems are typically seen as degraded and having no ecological value. In many cases, the modification of the ecosystem was done more than 100 years ago and may have had time to recover and become a refugia for species that were once more common in the landscape.

  4. 3. UPPLEVD TRYGGHET I EN TID AV ESKALERAT SKJUTVAPENVÅLD : En kvantitativ studie över betydelsen av storstadsområden och sociodemografiska egenskaper

    Kandidat-uppsats, Umeå universitet/Sociologiska institutionen

    Författare :Emelie Jäderberg; Maja Palm; [2024]
    Nyckelord :gang violence; gun violence; metropolitan areas; perceived security; shootings; socio-demographics;

    Sammanfattning : Gun violence has increased significantly in Sweden in the past years. The purpose of this study is therefore to investigate whether the number of shootings has an impact on the residents' sense of perceived security in Sweden's metropolitan areas, with the control variables of the socio-demographic characteristics gender, age and education level.

  5. 4. Skogslekplatsen : ett idéförslag för en lekmiljö i Hammarbyskogen

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Urban and Rural Development

    Författare :Rebecca Eurenius; [2024]
    Nyckelord :Lekmiljö; naturlek; landskapsarkitektur; temalekplats;

    Sammanfattning : Med förtätning av städer riskerar grönområden att minska i storlek och antal. Det kan leda till sämre förutsättningar för barns lek, vilket kan påverka deras hälsa och utveckling negativt. Att vistas eller leka i naturen har visats sig ha flera positiva effekter. LÄS MER

  7. 5. Can the disappearance of the forest orchid Goodyera repens be linked to clearcutting? : a spatial analysis using citizen science data from southern Sweden.

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Ines Diaz Garcia; [2024]
    Nyckelord :Goodyera repens; knärot; Artportalen; forestry; clearcut; citizen science; southern Sweden; conservation;

    Sammanfattning : Habitat transformation through forestry has an impact on boreal species in northern Europe. In Sweden, even-aged plantations with clearcut harvesting are forestry practices that affect the understory vegetation. This study focuses on the red-listed Goodyera repens, a rhizomatous evergreen orchid. LÄS MER
