  1. 1. Orsaker till och åtgärder för att förbättra ekonomin i förstagallringar på Åland

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Robert Hellgren; [2024]
    Nyckelord :förstagallring; ekonomiskt utfall; Åland;

    Sammanfattning : Röjningsbehovet på Åland är stort och andelen eftersatta ungskogar ökar för varje år. Det ekonomiska utfallet i förstagallringar är väldigt dåligt och i många fall obetydlig, vilket gör att intresset för att röja är litet. Det leder många gånger till att ungskogarna röjs för sent och ibland uteblir röjningen helt. LÄS MER

  3. 2. Behaviours of older adults in urban outdoor environments during warm days

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Sandra Lujic; [2023-08-18]
    Nyckelord :Older adults; urban outdoor environments; behaviour; preferences; thermal comfort;

    Sammanfattning : As a result of climate change, heat waves are expected to increase in frequency, duration, and severity, which is particularly threatening to the urban population. Vulnerable groups, including the older population, are more likely to be affected by adverse health effects due to heat exposure. LÄS MER

  4. 3. ACCESS TO URBAN COOL AND GREEN SPACES FOR OLD ADULTS IN GOTHENBURG – A GIS-BASED ANALYSIS OF RADIANT HEAT

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Robert Klein; [2023-01-19]
    Nyckelord :urban climate; heat stress; mean radiant temperature; SOLWEIG; urban vegetation; urban planning;

    Sammanfattning : Old adults are particularly vulnerable against heat stress. Considering the ageing society and the projected increase of heat events, planning for heat-resilient urban environments for old adults will become increasingly important. LÄS MER

  5. 4. Safety analysis of Railway Transportation of Dangerous goods

    Master-uppsats, KTH/Transportplanering

    Författare :Hengxu Liu; [2023]
    Nyckelord :;

    Sammanfattning : In the past decade, the demand for dangerous goods (DG) that can be used forindustrial, farming, mining, manufacturing, and pharmaceutical products has surgedwith the rapid development of industrialization. Almost 55,000 billion tonnekilometersof Dangerous Goods (DG) are transported annually by the railroad,accounting for approximately 51% of the total DG traffic volume in Europe. LÄS MER

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

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

    Författare :Ahsan Ali; [2023]
    Nyckelord :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;

    Sammanfattning : 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.
