  1. 1. Geologisk karaktärisering av den kambriska Faluddensandstenen i Östersjön och dess lämplighet för koldioxidlagring

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Kaisa Bengtsson; [2023]
    Nyckelord :Koldioxidlagring; djupt liggande akvifer; Faludden; St. Sutarve-2018; CO2-storage; deep saline aquifers; Earth and Environmental Sciences;

    Sammanfattning : The Geological Survey of Sweden (SGU) has spent several years investigating the Swedish bedrock to find suitable bedrock for geological storage of carbon dioxide. Deep saline aquifers are considered to have the greatest potential, and the Cambrian Faludden Sandstone subcropping in the Baltic Sea east of Gotland, shows great potential as a storage aquifer.

  3. 2. The role of bed sediments for fractionation of phosphorus in remediated ditches in Sweden

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and Environment

    Författare :Emma Ryding; [2022]
    Nyckelord :Phosphorus fractionation; agricultural stream; sediment; two-stage ditch; eutrophication;

    Sammanfattning : Sweden’s environmental quality objectives “A varied agricultural landscape” and “Zero eutrophication”, aims to ensure food production while reducing negative impact from fertilizers on the environment. The input ceilings of nutrient concentrations in the Baltic Sea are still critical. LÄS MER

  4. 3. Method evaluation for probing DNA sorption to clay minerals : Evaluation of fluorescent and spectroscopic quantification of DNA as well as DNA interactions of Kaolinite and Montmorillonite

    Kandidat-uppsats, Umeå universitet/Kemiska institutionen

    Författare :Oskar Wangdell; [2022]
    Nyckelord :;

    Sammanfattning : The association of DNA/RNA to mineral surfaces is an emerging field with widespread applications from biotechnological solutions to paleogenetics. Evaluating available methods to quantify adsorption will be essential to further investigate how to control and predict loading of DNA onto minerals. LÄS MER

  5. 4. Do Clay Minerals affect the thickener operationin Chuquicamata mine, Calama, Chile?

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

    Författare :Chris Soto; [2020]
    Nyckelord :Mine; clay minerals; mineral processing;

    Sammanfattning : Chuquicamata mine mineralogy has been studied performing both X-Ray Diffraction (XRD) and X-RayFluorescence (XRF) to determine whether there is any influence in the thickener operations. Thetargeted minerals were the clay group because of their detrimental effect on mining operations asmodify the rheology of the suspensions. LÄS MER

  7. 5. Submarine Alteration of Seamount Rocks in the Canary Islands: Insights from Mineralogy, Trace Elements, and Stable Isotopes

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Aduragbemi Oluwatobi Sofade; [2018]
    Nyckelord :Canary Islands; seamounts; submarine alteration; trace elements; nannofossils; Kanarieöarna; djuphavsberg; undervattensomvandling; spårämnen; nanofossiler;

    Sammanfattning : Seamounts play an important role in facilitating the exchange of elements between the oceanic lithosphere and the overlying seawater. This water-rock interaction is caused by circulating seawater and controls the chemical exchange in submarine and sub-seafloor rocks. LÄS MER
