    Sammanfattning : Acidification was one of the biggest environmental issues during the 20th centaury, especially in Sweden since acidic emissions from other regions ended up in the ground and water here. In this study, data from several lakes in Ulricehamn Municipality was analysed with consideration of acidification. LÄS MER

  3. 2. Methods to Predict Hull Resistance in the Process of Designing Electric Boats

    Master-uppsats, KTH/Marina system

    Författare :Felicia Ahlstrand; Elin Lindbergh; [2020]
    Nyckelord :;

    Sammanfattning : Combustion engines in boats cause several environmental problems, such as greenhouse gas emissions and acidication of oceans. Most of these problems can be reduced by replacing the combustion engines with electric boats. LÄS MER

  4. 3. Skogsbrukets påverkan på övergödning och försurning

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Sammanfattning : The road transport sector is heavily dependent on fossil-fuel based technologies, and as a result, contribute a significant share towards climate change and other environmental problems. If the transport sector is to reduce its adverse impacts on climate change, then it requires a global shift towards low-carbon technologies. LÄS MER

  7. 5. Nitrogen flow in Scania : substance flow analysis on a regional level

    Master-uppsats, SLU/Dept. of Energy and Technology

    Författare :Johanna Hellstrand; [2015]
    Nyckelord :substance flow analysis; fertilizer; sewage sludge; wastewater; urine separation; manure;

    Sammanfattning : In this thesis, the flows of reactive nitrogen (Nr) in Scania were investigated and quantified. The thesis was also intended to form a basis for comparison between the urban nitrogen flow and other flows of nitrogen within Scania. The management of nitrogen in society has disturbed the natural nitrogen cycle. LÄS MER
