  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

  6. 5. Restoration strategies in boreal forests : prescribed burning and gap cutting effects on plant diversity and community composition

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Clara Espinosa Del Alba; [2020]
    Keywords : restoration ecology; boreal forest; fire; gap cutting; biodiversity; voluntary set-asides; vascular plants; bryophytes; forest management;

    Abstract : The boreal biome is one of the largest in the world and their forests have been widely exploited for centuries. Consequently, it has suffered ecological simplification and loss of biodiversity. Under these circumstances passive conservation is no longer enough and active restoration techniques need to be tested. READ MORE
