  1. 11. Evaluation of PFAS removal from nanofiltration membrane concentrate using foam fractionation

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :William Stefansson; [2022]
    Nyckelord :PFAS; Aeration foam fractionation; Nanofiltration membrane; DWTP; Surfactant; PFAS; Skumfraktionering; Nanofiltration; Vattenverk; Surfaktant;

    Sammanfattning : Per- and polyfluorinated substances (PFASs) have become an urgent topic in the water treatment industry in recent years as a consequence of new scientific discoveries of the correlation between the ingestion of some PFASs and their toxicity in humans and other organisms. PFASs are synthetic compounds present in a variety of products. LÄS MER

  3. 12. Visibility in Smoke With Different Extinction Coefficients

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Lea Elhokayem; [2022]
    Nyckelord :Visibility; smoke; exit sign; extinction coefficient; visibility constant; evacuation; Technology and Engineering;

    Sammanfattning : Visibility in smoke has since the 1970s gained some attention, mostly after Tadahisa Jin ran the experiments which helped him develop todays widely used visibility equation. By showing that visibility can be assumed to be inversely proportional to the extinction coefficient by a visibility constant (equal to 8 for light emitting sign and 3 for light reflecting), Jin opened up new doors for researchers who were testing out his theory by going around experimenting in different ways and also by showing that there is way for more research to be done.

  4. 13. Nötkreaturs betningsbeteende på bränt och på obränt naturbete

    Kandidat-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :My Strömgren; [2021]
    Nyckelord :betningsbeteende; brand; nötkreatur; naturbete; obränt bete; bränt bete;

    Sammanfattning : Habitats worldwide have undergone changes which have had effects on the living conditions for many species. Some landscapes have opened up due to agriculture, others have changed into fragmented monocultural habitats due to forestation. LÄS MER

  5. 14. Dimensionering av ett flervåningshus i KL-trä med hjälp av FEM-Design : En jämförelse mellan betong och KL-trä

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Philip Karlsson; Josefin Winell; [2021]
    Nyckelord :FEM-Design; CLT; FEM-design; KL-trä;

    Sammanfattning : Det har av olika anledningar blivit mer populärt att bygga flervåningshus i trä vilket har lett till en utveckling av material i trä. Korslimmat trä även kallat KL-trä är en konsekvens av denna utveckling i Sverige och precis som för andra stommaterial används datorprogram för att rita hus i KL-trä. LÄS MER

  7. 15. Impact of fire and frost drought events on vegetation greenness and albedo in Subarctic Scandinavia

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Elin Backström; [2021]
    Nyckelord :Physical Geography and Ecosystem analysis; Vegetation Greenness; Albedo; Fire; Frost Drought; Earth and Environmental Sciences;

    Sammanfattning : With climate change, the frequency in climate extremes such as drought, heavy rainfalls, and extreme temperatures is predicted to increase. These extremes can potentially stress and damage vegetation over large areas, leading to altered carbon cycle, vegetation greenness, albedo, and shifted species composition. LÄS MER
