  1. 16. Traits of peat- and upland-derived stream dissolved organic carbon in the permafrost region around Abisko, northern Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Nora Kainz; [2021]
    Keywords : physical geography; ecosystem analysis; permafrost degradation; DOC; DOC concentration; stable isotope carbon signature; DOC quality; DOC degradation; Atmospheric Sciences and Biogeochemical Cycles; Earth and Environmental Sciences;

    Abstract : Climate change-induced thawing of permafrost mobilizes previously frozen carbon of high potential reactivity, thereby, fuelling microbiological production of greenhouse gases. For this work, an analysis of the quantity, quality, and bioreactivity of DOC in streams from the Stordalen discontinuous permafrost catchment was carried out with stream water samples during the relatively warm summer of 2018.

  3. 17. Sustainable stormwater management in Stockholm's inner city

    University essay from KTH/Urbana och regionala studier

    Author : Nils Brattgård; [2021]
    Keywords : Stockholm; Sustainable Stormwater Management; Stormwater; Runoff; Green Infrastructure; Structural Soil; Trees; Constructed Wetlands; Wet pond; Green roof; Green wall; Institutional challenges; Technical challenges;

    Abstract : Much like other cities Stockholm has traditionally used a technical system for managing stormwater. With time this system has become overburdened and has led to large environmental concerns. To reach water quality goals set by the EU Stockholm needs to decrease pollution released to recipients by 70-80%. READ MORE

  4. 18. Intelligent hydropower : Making hydropower more efficient by utilizing machine learning for inflow forecasting

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Jakob Claesson; Sam Molavi; [2020]
    Keywords : machine learning; inflow forecasting; hydropower; HBV model; maskininlärning; tillrinningsprognostisering; vattenkraft; HBV-modell;

    Abstract : Inflow forecasting is important when planning the use of water in a hydropower plant. The process of making forecasts is characterized by using knowledge from previous events and occurrences to make predictions about the future. Traditionally, inflow is predicted using hydrological models. READ MORE

  5. 19. Ultrasonic Assisted Drying and its Effect on 3D Printability of Minced Beef and Other Foods

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Viktor Lindström; [2020]
    Keywords : Drying; Convection drying; Ultrasound; Ultrasonic drying; 3D-Printing; 3D-Printability; Food; Meat; Beef; Food technology; Livsmedelsteknologi; Technology and Engineering;

    Abstract : The aim of this master thesis project was to investigate the impact on drying kinetics of ultrasound during air drying by a new ultrasonic transducer, on which a patent application has been filed by CSIRO. Convection drying using hot air is currently the conventional method of drying in the industry due to its simplicity and low cost. READ MORE

  6. 20. Assessment of coastal erosion to create a seagrass vulnerability index in northwestern Madagascar using automated quantification analysis

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Nat Arslan; [2020]
    Keywords : Seagrass; Coastal erosion; Vulnerability index; Python; Google Earth Engine; Deforestation; Turbidity; Mangrove; Madagascar;

    Abstract : The seagrass extent has been declining globally. The human activities that are most likely to cause seagrass loss are those which affect the water quality and clarity. However, turbidity following coastal erosion is often left out from marine ecosystem vulnerability indices. READ MORE
