  1. 1. God grundvattenkvalitet?

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Elvira Källberg; [2019]
    Nyckelord :Drinking water; pollution Bergaån; iron; manganese PFAS and pesticides; Earth and Environmental Sciences;

    Sammanfattning : Clean drinking water is a crucial part of a healthy society. During the last decades, a lot of emissions from different sources have put the drinking water sources that are used today at risk of pollution. LÄS MER

  2. 2. Kartläggning av riskområden för inducerad infiltration i grundvattentäkter

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Martin Sundström; [2019]
    Nyckelord :Induced infiltration; groundwater; drinking water; Gävleåsen; Vanåsen; Inducerad infiltration; grundvatten; dricksvatten; Gävleåsen; Vanåsen;

    Sammanfattning : Uttag av grundvatten är viktigt då det förser nästan hälften av befolkningen i Sverige med dricksvatten. Vid uttag som leder till avsänkning av grundvattennivån kan en inträngning av organiskt material uppstå om det finns ett intilliggande ytvattendrag, ett fenomen som kallas inducerad infiltration.

  3. 3. Introducing a central receiver system for industrial high-temperature process heat applications : A techno-economic case study of a large-scale CST plant system in a South African manganese sinter plant

    Master-uppsats, KTH/Kraft- och värmeteknologi; KTH/Kraft- och värmeteknologi

    Författare :Maria Hallberg; Elin Hallme; [2019]
    Nyckelord :Solar energy; concentrating solar thermal; CST; central receiver system; CR; HelioPod; high-temperature process heat; manganese; business case; Solenergi; koncentrerad termisk solvärme; CST; soltorn; HelioPod; högtempererad processvärme; mangan; affärsmodell;

    Sammanfattning : The objective of this thesis was to investigate the potential for introducing a concentrating solar thermal (CST) central receiver plant system based on flexible heliostats - HelioPods - to provide high-temperature process heat in industrial applications. A CST plant system was designed in MATLAB, optically simulated for three design days in the ray-tracing software Tonatiuh and further analyzed in MATLAB by interpolating the results for each hour of the year.

  4. 4. Purification, functional characterization and crystallization of the PerR peroxide sensor from Saccharopolyspora erythraea

    Master-uppsats, Uppsala universitet/Strukturbiologi

    Författare :Grim Elison Kalman; [2019]
    Nyckelord :structural biology; cell culture; protein expression; genetic engineering; spectroscopy; X-ray crystallography; small angle X-ray scattering; SAXS; transcription factor; PerR; metal binding; antibiotics; Saccharopolyspora erythraea; S. erythraea; soil bacterium; actinobacteria; actinomycetes; oxidative stress; peroxide stress; structure determination; characterization; stabilization; peroxide sensor; iron sensor; manganese sensor; metalloprotein; metal ion homeostasis; metal ion; prokaryotic; strukturbiologi; cellodling; proteinuttryck; genteknik; spektroskopi; röntgenkristallografi; småvinkel-röntgenspridning; SAXS; transkriptionsfaktor; PerR; metallbindande; antibiotika; Saccharopolyspora erythraea; S. erythraea; jordartsbakterie; Aktinobakterier; Actinobacteria; Actinomycetes; oxidativ stress; peroxid stress; strukturbestämning; karaktärisering; stabilisering; peroxidsensor; järnsensor; mangansensor; metalljonshomeostas; metalljoner; prokaryot;

    Sammanfattning : This report summarizes the work on the cloning, expression, and purification of PerR, a metal sensing regulator from Saccharopolyspora erythraea and the subsequent characterization using small angle X-ray scattering and other biochemical methods. The report aims to provide an insight into prokaryotic metal homeostasis, provide a better understanding of how PerR works and provide valuable information for the continued work on the crystallization of PerR.

  5. 5. Mineral elements in clover- and grass forage in Sweden

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Kajsa Lätt; [2019]
    Nyckelord :soil; maps; forage; macro minerals; micro minerals;

    Sammanfattning : Minerals are essential elements for all living organisms. Plants and animals need minerals to function and maintain a balanced physiological state. Minerals are also important in the ecological cycle. The minerals originate in the soil and makes the foundation of the plants nutritional value for the animals. LÄS MER
