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

    University essay from SLU/Dept. of Soil and Environment

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

    Abstract : 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. READ MORE

  3. 2. 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

    University essay from Umeå universitet/Kemiska institutionen

    Author : Oskar Wangdell; [2022]
    Keywords : ;

    Abstract : 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. READ MORE

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

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Chris Soto; [2020]
    Keywords : Mine; clay minerals; mineral processing;

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/Institutionen för geovetenskaper

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

    Abstract : 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. READ MORE
