  1. 11. The geochemical status of the surface water and the sediments in the estuary of the Sangis River, Kalix, Sweden

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Anton Sandberg; [2023]
    Nyckelord :Framboidal pyrite; dredging; Sangis River; estuary; redox ladder; sediment; sediment cores; SEM-EDS;

    Sammanfattning : It has been common in forestry and agriculture to drain waterlogged areas through ditching in order to cultivate them. The ditches that drain water are usually connected to some watercourse, such as a river. LÄS MER

  3. 12. Svenska avfallsabonnemang - En studie om utformning av avfallsabonnemang och prissättning som incitament

    Magister-uppsats, Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Simon Andersen Staahlnacke; [2023]
    Nyckelord :recycling; waste; recycling program; household; curbside collection; economic incentive; Earth and Environmental Sciences;

    Sammanfattning : Recycling reduces the need for new raw materials and greenhouse gas emissions. In addition, the new waste legislation from the EU and the Swedish government imposes higher recycling requirements on Swedish municipalities. LÄS MER

  4. 13. Inclusion of more sources in a commercial brachytherapy Monte Carlo

    Kandidat-uppsats,

    Författare :Philip Wiman; Emil Forsberg; Robin Vestling; [2023]
    Nyckelord :;

    Sammanfattning : Brachytherapy is a cancer treatment method where a solid radioactive source is placed inside the body in order to target cancer cells with a high dose of radiation while minimizing damage to surrounding healthy tissue. The most common method for treatment planning in brachytherapy is the TG43 formalism where the whole patient geometry is treated as water. LÄS MER

  5. 14. Numerical Simulations of Metal Recovery for Battery Recycling

    Master-uppsats, KTH/Processteknologi

    Författare :Morgan Ölander; [2023]
    Nyckelord :Batteriåtervinning; Metall återvinning; Kristallisation; Computational Fluid Dynamics CFD ; Populationsbalansmodellering; Battery recycling; Metal recovery; Crystallisation; Computational Fluid Dynamics CFD ; Population balance modelling;

    Sammanfattning : Den pågående elektrifieringen av transport och samhälle kräver utveckling av nya metoder för återvinning av batterier. Hydrometallurgi som fokuserar på selektiv kristallisation av metaller är ett intressant alternativ för dessa ändamål. Dessa system kan studeras genom modellering och simulering. LÄS MER

  7. 15. Uptake and retainment of radionuclides in edible mushrooms – from fruiting to cooking

    Master-uppsats,

    Författare :Delshad Mansour Ayoubi; [2022-12-06]
    Nyckelord :Medical physics; Activity concentration; Transfer coefficient; Dose;

    Sammanfattning : Purpose: The purpose of this study was to study the uptake, distribution and transfer of Mn-54, Zn-65, U-238, U-235, U-234, and Po-210 in mushrooms and their respective caps and stalks, the effects of chelates and ligands, and the potential release of radionuclides during a cooking procedure. Introduction: Fungi are organisms that are composed of a fruiting body (mushroom) and tubular hyphae, that branches out into complex networks called mycelium. LÄS MER
