  1. 1. Geological 3D Modelling ofthe File Hajdar Quarry, Slite

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Friberg Nils; [2023]
    Nyckelord :3D-modelling; Cementa; limestone; resistivity; Gotland; 3D-modellering; Cementa; kalksten; resistivitet; Gotland;

    Sammanfattning : Located on the island of Gotland, Sweden, the File Hajdar limestone quarry is an important locality for domestic cement production. With depositional settings generally related to shallow sea carbonate ramps, the lithologies encountered on File Hajdar range from reef-associated limestone units to more basinal deposition of marls.

  3. 2. Potential att lagra koldioxid genom in situ-karbonatisering i Sundsvall och Örnsköldsvik

    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Anna Öjebrandt; [2023]
    Nyckelord :In situ-karbonatisering; koldioxidlagring; Bio-CCS; BECCS;

    Sammanfattning : Samhället står inför stora utmaningar för att lyckas nå målet i Parisavtalet om att begränsa den antropogena uppvärmningen till 1,5˚C samt det nationella klimatmålet om att uppnå netto-noll-utsläpp av växthusgaser senast år 2045. Geologisk lagring av koldioxid (CCS, Carbon Capture and Storage) lyfts fram som en nyckelåtgärd för att reducera koldioxidutsläppen och därigenom uppnå dessa mål. LÄS MER

  4. 3. 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

    Sammanfattning : In Sweden, paperboard has been an essential product in the export market and is mainly used as packaging material. Packaging materials corresponded to 66% of all paper and board production in Sweden for the year 2020, which is an increase of 2,5% compared with the previous year [1]. LÄS MER

  7. 5. Geomechanical testing of non-hardening grout : for determination of flowability and strength properties

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geoteknologi

    Författare :Axel Barrdahl; [2022]
    Nyckelord :Non-hardening; Grout; Embankment dam; Repair; Fall cone; Uniaxial Compressive Strength; UCS; Triaxial;

    Sammanfattning : Due to an increasing amount of aging tendencies in Swedish embankment dams, failures such as internal erosion has become a more common problem. Internal erosion is a phenomenon where certain soil material within the embankment dam is removed, often over a longer period of time. LÄS MER
