  1. 1. WEAR RESISTANT MULTI FUNCTIONAL POLYMER COATINGS

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

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

    Abstract : 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. READ MORE

  3. 2. Laboratory Investigation of Quarry Fines for Use in the Construction Industry

    University essay from KTH/Jord- och bergmekanik

    Author : Antonia Filippidi; [2022]
    Keywords : quarry fines; water content; optimum moisture content; maximum dry density; bearing capacity;

    Abstract : Quarry fines are by-products of the aggregate extraction and productionprocesses. Because such fine material cannot be marketed, it becomes aburden for the aggregate industry, resulting in stockpiles of financiallyunexploited material. READ MORE

  4. 3. The effectivity of vacuum impregnation with glycerol and secondary metabolites on electroporated arugula leaves to improve freezing stability.

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Oscar de Kuijer; [2021]
    Keywords : Pulsed electric field PEF; Arugula; Electroporation; Secondary metabolites; Glycerol; Food engineering; Livsmedelsteknik; Technology and Engineering; Agriculture and Food Sciences;

    Abstract : Freeze damage is a common issue in many food items. The cellular dehydration caused by freezing can be prevented through addition of a cryoprotectant. Research has shown that it is possible to improve the freezing tolerance of plant materials by addition of cryoprotectants, which forms hydrogen bonds with water molecules. READ MORE

  5. 4. Evaluation of air entraining behaviour in concrete using computer aided methods on hardened samples

    University essay from KTH/Betongbyggnad

    Author : Jakub Pawlowicz; [2019]
    Keywords : concrete; air voids; air entraining; AEA; blast furnace slag; BFS; flat-bed scanner; BubbleCounter; traverse method;

    Abstract : Increasing awareness of sustainability in the concrete industry forces structural design and executionto focus on avoiding costly and unpredictable maintenance action, instead paying higher attention todamage prevention by direct actions on early stages of production. One of such approaches, whichdeals with the problem of freezing and thawing deterioration, is intentional air bubble introductionto the concrete mix. READ MORE

  6. 5. Effects of climate change on freezing damage in three subarctic bryophyte species

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Marlene Kassel; [2017]
    Keywords : freezing damage; bryophytes; subarctic; climate change;

    Abstract : Climate change is expected to have a strong impact on subarctic ecosystems. Increased temperatures as well as altered precipitation and snow cover patterns are predicted to change species distribution and affect biogeochemical processes in the subarctic tundra. READ MORE
