  1. 1. Perception of urban blue-green infrastructure during winter in Gothenburg

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Mikaela Torell; [2023-08-17]
    Keywords : perception; greenery; water; urban environment; recreation;

    Abstract : Life in urban settlements is often associated with insufficient physical activity and continuous stress. By implementing blue-green infrastructure (BGI) consisting of parks, trees, ponds, and rain gardens, amongst others, recreational values can be provided for the residents. READ MORE

  3. 2. Effect of temperature on early stage adhesion during TiAlN sliding against Inconel 718 and Stainless steel 316L : High temperature tribology

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

    Author : Ahsan Ali; [2023]
    Keywords : High temperature tribology; Early-stage adhesion; Adhesive wear; Friction; Wear resistant coatings; Physical vapour deposition PVD coatings; TiAlN; Tungsten carbide WC Co ; Difficult to machine super alloys; Inconel 718; Stainless steel 316L; High-performance materials; Abrasion; Oxidation; Chipping; Ploughing; Characterization;

    Abstract : High-performance materials such as stainless steels and nickel based super alloys are widely used in demanding applications where high mechanical and thermal properties are required. The applications of super alloys are mainly found in jet engines, power plants and gas turbines demanding high fatigue strength, corrosion and oxidation resistance as well as wear resistant properties.
