  1. 1. Vilken effekt har vassleprotein på benmineraldensitet? En systematisk litteraturöversikt bland vuxna ≥ 35 år.

    Kandidat-uppsats, Göteborgs universitet/Institutionen för medicin

    Författare :Felicia Andersson; Clara Johansson; [2024-02-09]
    Nyckelord :Whey protein; bone mineral density; adults; Vassleprotein; benmineraldensitet; vuxna;

    Sammanfattning : Syfte: Syftet med denna systematiska litteraturöversikt är att undersöka om supplementering av vassleprotein har någon påverkan på bentäthet (BMD) hos vuxna ≥35 år. Metod: Litteratursökningen gjordes i två databaser, Pubmed och Scopus. Sökord för blocken var vassleprotein, BMD och randomiserade kontrollerade studier (RCT). LÄS MER

  3. 2. The paint loss of Callmander’s stained glass windows: An investigation of the prevalence and causes behind the paint loss on Callmander and Svenska Glasmåleri AB’s stained glass windows

    Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Victor Eisfeldt; [2024-02-06]
    Nyckelord :Grisaille; Stained-glass; Callmander; Vitreous Paint;

    Sammanfattning : This MA-thesis investigates the loss of grisaille paint in the stained-glass windows created by the artist Reinhold Callmander and Svenska Glasmåleri AB, with the aim of understanding the prevalence as well as the reasons behind the issue. Stained glass has historically been in the periphery of conservation. LÄS MER

  4. 3. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)

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

    Författare :Grigore-Leon Ratiu; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. LÄS MER

  5. 4. Simulation-based discrimination of Crab pulsar models with XL-Calibur

    Master-uppsats, KTH/Fysik

    Författare :Dennis Åkerström; [2024]
    Nyckelord :Astroparticle Physics; Astrophysics; Detector Physics; Simulation; Theoretical Physics; Engineering Physics; Pulsar models; Crab pulsar; Astropartikelfysik; Astropartikelfysik; Detektorfysik; Simulering; Teoretisk Fysik; Teknisk Fysik; Pulsar modeller; Krabbpulsaren;

    Sammanfattning : Polarisation of X-ray light is being investigated with polarimeters to extend the borders of what can be observed. Distant compact objects, such as pulsars, that are to small on the sky to be analysed with imaging can be investigated by analysing the polarisation of the emitted light. This can reveal physics previously hidden by their small nature. LÄS MER

  7. 5. Decay Chains of Fast Alpha Emitters in the Actinide Region

    Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Författare :Tanvir Sayed; [2024]
    Nyckelord :alpha decay; alpha emissions; fine structure; decay chain; decay scheme; alpha spectrometry; actinide; nucleus; nuclear structure; nuclear states; energy levels; uranium isotopes; U310 experiment; parasitic runs; decay station; TASISpec ; moving window deconvolution; digitisers; alpha-gamma coincidence; 221-Th decay; fine structure of alpha decay to 217-Ra; GSI; Gamow s theory; Geiger-Nuttall; chain search; short half-lives; Physics and Astronomy;

    Sammanfattning : With the advent of increasingly advanced spectroscopic instruments after the turn of the century, it has become accessible to unravel the structure of instantly ‘vanishing’ nuclei, with lifetimes as short as 1 μs, and responsible for pile-up events in analog electronics. Experimental data has been recorded by the Nuclear Structure Group at Lund University for 48Ca/50Ti + nat. LÄS MER
