  1. 1. WEAR RESISTANT MULTI FUNCTIONAL POLYMER COATINGS

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Pranay Kumar Parsi; [2023]
    Nyckelord :Polymer coatings; Materials; Tribology; Wear resistant; Ice adhesion; Freezing delay; Anti-icing de-icing;

    Sammanfattning : This study aims to develop coatings which show wear resistant behaviour along with multiple functions such as improved ice adhesion, better freezing delay etc which help in improving the effectiveness of the wind turbine efficiency. The significance of anti-icing/de-icing solutions for wind turbines is emphasized since ice accretion can cause serious issues in generation of power and might lead to damage of blades. LÄS MER

  3. 2. Cultivating oleaginous yeast on spent mushroom substrate and logging residues hydrolysate : an assessment of yeast growth on side product substrates from the food, agriculture, and forestry industry

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Robin Lukic; [2023]
    Nyckelord :Lignocellulose; side products; oleaginous yeast; yeast oil; microtiter plate system; redox indicator; yeast growth; spent mushroom substrate hydrolysate; logging residues hydrolysate;

    Sammanfattning : There is an interest in finding alternatives to vegetable oils because of negative environmental impact. Many green sectors generate an abundant amount of side products that are inedible and consist in large of lignocellulose rich materials. LÄS MER

  4. 3. A changing energy security environment – a review of alternative energy carriers for light duty vehicles

    Master-uppsats, Försvarshögskolan

    Författare :Julia Nilsson; [2023]
    Nyckelord :Supply chain; Logistic; Energy security; Light duty vehicle;

    Sammanfattning :   The increasing energy demand and its impact on the climate around the world has evoked several sectors´ efforts in order to develop and implement sustainable technologies. Political incentives and companies go toward great changes when it comes to reduction of energy sources from fossil-origins in order to reduce greenhouse gas emissions and achievement of energy security.

  5. 4. UNDERSÖKNING AV VÄXTOLJOR SOM FÖRYNGRINGSMEDEL OCH ERSÄTTNING FÖR BITUMEN VID ÅTERVINNING

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

    Författare :Maher El-Tahan; [2022]
    Nyckelord :Asfalt; bitumen; återvinning; föryngring; växtolja; mineralolja; Technology and Engineering;

    Sammanfattning : Asfaltbeläggningar behöver fortlöpande repareras och slutligen bytas ut efter nötning och sönderbrytning men också av att asfalten förlorat sin eftergivlighet genom åldring. Det är en naturlig förändring som påverkas av luftens syre och solens strålning men också av ämnen i miljön. LÄS MER

  7. 5. Fatty acid composition in Arctic char (Salvelinus alpinus) fed with red yeast biomass : a comparison between large and small specimens

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Sofia Jacobsson; [2022]
    Nyckelord :Fatty acid composition; lipid content; oleaginous yeast; Arctic char Salvelinus alpinus ; aquaculture;

    Sammanfattning : Oleaginous yeast has shown to be a promising alternative to replace vegetable oils in fish feed. A problem in aquaculture is that different growth rates can be observed among farm-raised fish, supressing the productions full potential. When different growth rates are observed, it can be questioned if the fish assimilate the feed to the same extent. LÄS MER
