  1. 1. Potassium in the Galactic Bulge - as traced by microlensed dwarf & sub-giant stars

    Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Lukas Jönsson; [2023]
    Nyckelord :Nucleosynthesis; Galactic Bulge; Potassium; Non-Local-Thermal-Equilibrium; Physics and Astronomy;

    Sammanfattning : During this report the potassium (K) trend in the Galactic Bulge, with respect to metallicity and various α-elements, has been computed and evaluated by a method of line synthesis on the 7698.96 ̊A KI line (7699 KI), where Non-Local-Thermal-Equilibrium (NLTE) effects have been considered.

  3. 2. Possibilities of Reducing Internal Scrap Rates and Increase Scrap Recyclability of Dilute Copper Alloys from Vertical Upwards Continuous Cast (VUCC) Process

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Minna Olsson; [2023]
    Nyckelord :metallurgy; copper; alloy; continuous casting; materials chemistry; Technology and Engineering;

    Sammanfattning : Copper and copper alloys are important material systems for the electrification of society. The high workability of the materials makes them appropriate in numerous different applications which require highly conductive properties. LÄS MER

  4. 3. Development and understanding of a model V2O5/anatase TiO2(101) SCR catalyst

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Johanna Paulsson; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : A model V2O5/ anatase TiO2(101) SCR catalyst is studied with the purpose of developing and understanding the reaction mechanism through which this catalyst reduces NOx. Several reaction mechanisms have been proposed for this catalyst in the past, but there is still no agreement on which of these describe the reaction the best, if any. LÄS MER

  5. 4. EXPRESSION OF SUGAR BEET HEMOGLOBIN IN PICHIA PASTORIS

    Master-uppsats, Lunds universitet/Tillämpad biokemi; Lunds universitet/Beräkningskemi

    Författare :Johan Pettersson; [2022]
    Nyckelord :Pichia pastoris; expression; sugar beet; hemoglobin; km71; ppic9; ppic3.5; phil-s1; applied biochemistry; Biology and Life Sciences;

    Sammanfattning : People who don’t eat meat can suffer from iron deficiency due to the lower efficiency of absorption of non-heme iron compared to heme iron. The aim of this master thesis was to explore the possibilities of producing a plant-based alternative of heme-iron by evaluating the efficiency of expression of sugar beet hemoglobin in the methylotrophic yeast Pichia pastoris.

  7. 5. Diffuse dust at Boliden Bergsöe investigated through X-ray Fluorescence Spectroscopy

    Master-uppsats, Lunds universitet/Ergonomi och aerosolteknologi

    Författare :Linnea Savér; Marcus Norlin; [2022]
    Nyckelord :Multi-metals monitoring; On-line monitoring; Aerosols; Diffuse dust; Environmental management; Secondary lead smelting; Technology and Engineering;

    Sammanfattning : Boliden Bergsöe operates a secondary lead smelter for recycling of lead-acid batteries, located in the industrial area of Landskrona. Measurements to monitor levels of airborne particles have been conducted in several locations in Landskrona since 1977. LÄS MER
