    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Fredrik Karlsson; [2022-09-01]
    Nyckelord :Treeline evolution; Tree growth; Norway spruce; central Scandinavian mountains; Blue Intensity;

    Sammanfattning : In the context of global change, mountain regions have received increased interest in recent times with researchers trying to answer how such regions may be affected by a changing climate. Treeline environments are sensitive to the impacts of climate change which may significantly alter the characteristics of the regions. LÄS MER

  3. 2. Gödslingseffektens varaktighet i gallrade tallbestånd i södra Norrland

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

  5. 4. Attenuation of structure-borne vibrations induced by trains passing railway switches

    Master-uppsats, KTH/Marcus Wallenberg Laboratoriet MWL

    Författare :Fredrik Lindström; [2020]
    Nyckelord :;

    Sammanfattning : The study of structure-borne vibrations caused by railway traffic is becoming increasingly relevant along with the expansions of cities, as building projects are forced towards more sensitive areas, e.g closer to railway tracks. With high enough vibration levels, there is a risk for human annoyance inside buildings. LÄS MER
