  3. 2. Performance Evaluation of a High Temperature Borehole Thermal Energy Storage Under Influence of Groundwater Flow

    University essay from KTH/Energiteknik

    Author : Max Hesselbrandt; [2021]
    Keywords : ;

    Abstract : Recent years have seen a growing interest in large-scale high-temperature borehole thermal energy storage (HT-BTES) as a means to store industrial waste heat and solar energy between the seasons. A profound understanding and characterization of the thermal and hydraulic processes involved in such systems is required for the optimal design as well as for environmental assessments of the storage.

  4. 3. Inhibited surface-thiols in Geobacter sulfurreducens : Mercury uptake and methylation rates

    University essay from Umeå universitet/Kemiska institutionen

    Author : Andreas Granström; [2021]
    Keywords : ;

    Abstract : Due to daily human (anthropogenic) industrial activity, a lot of elemental mercury (Hg0) has been released to the atmosphere. The mercury can then spread globally, since mercury has the ability to remain atmospheric for up to a year. When mercury deposits, it can end up in anaerobic environments such as sediments and soil.

  5. 4. Patterns and factors affecting brownification in a boreal river

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Emil Winqvist; [2021]
    Keywords : Bolmen; brownification; precipitation; discharge; sulfur deposition; land use; trend analysis; Technology and Engineering;

    Abstract : During the last decades a brownification of the lakes and streams in the northern hemisphere has been observed. The change has been attributed to an increase of organic content in the water, leached from the top soil layers, called humic substances. READ MORE

  6. 5. Attityder kring föryngring hos privata skogsägare i Mellansverige

    University essay from SLU/School for Forest Management

    Author : Torbjörn Jakobsson; Gustav Sven Hultén; [2021]
    Keywords : markberedning; enkät; intervju; återbeskogning;

    Abstract : Skogens roll blir allt viktigare för samhället i takt med att vi ställer om till en bioekonomi och för att säkra den framtida skogsråvaran som kommer behövas är det viktigt att uppnå en godkänd föryngring. Under senare år har andelen godkända föryngringar ökat, mycket tack vare effektivare föryngringsåtgärder bland annat högre utnyttjande av markberedning och plantering. READ MORE
