  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. Improvement of anautomatic networkdrawing algorithm in thecontext of utility networks

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Hyacinthe Ménard; [2024]
    Nyckelord :District Heating Network; Mathematical Optimization; Python; Fjärrvärme; Optimeringslära; Python;

    Sammanfattning : The European Union’s ambitious climate targets necessitate substantial reductions in greenhouse gas emissions, particularly within the heating and cooling sector, which accounts for a significant portion of energy consumption. District Heating and Cooling (DHC) systems emerge as a key solution for decarbonizing this sector by enabling high efficiency heat production and the integration of renewable and carbon-neutral energy sources.

  4. 3. 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

    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. Exploring patterns in risk factors for bark beetle attack during outbreaks triggered by drought stress with harvester data on attacked trees: A case study in Southeastern Sweden

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Nikolaos Kouskoulis; [2023]
    Nyckelord :Geography; GIS; Geographic Information Science; Forest ecosystems; Bark beetle outbreak; Southeastern Sweden; Predisposing factors; Triggering factors; Drought stress; Earth and Environmental Sciences;

    Sammanfattning : ABSTRACT Raising temperatures and climate variability have intensified extreme weather events worldwide. These extremes can enhance and trigger possible pest outbreaks. Bark beetle attacks have become a major concern in regions with extensive spruce forest areas. Southeastern Sweden has faced repeated outbreaks resulting in widespread tree loss. LÄS MER
