  1. 1. Impact of nitrogen availability and nitrogen structural composition on fungal enzymatic activity and growth : how nutrient availability governs response and development of three saprotrophic Basidiomycetes

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Bella Strid; [2024]
    Nyckelord :nitrogen; tannins; condensed tannins; MnP; manganese peroxidase; peptidase; saprotrophic basidiomycetes;

    Sammanfattning : Fungi excrete a wide variety of extracellular enzymes to scavenge for nutrients, such as the often scarce yet essential nutrient nitrogen. All fungi produce highly specialized hydrolytic enzymes, e.g. peptidases, that depolymerize organic molecules. LÄS MER

  3. 2. FÖRUNDERSÖKNING AV EN EGYPTISK POLYKROM KISTA Dokumentation, tillståndsbeskrivning och analys

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Ida Kingo; [2023-06-15]
    Nyckelord :consolidation; heritage science; ancient Egypt; polychrome coffin; XRF; FTIR;

    Sammanfattning : On ancient Egyptian polychrome art and mainly on coffins, it was normal practice to apply a thick ground and gesso before painting the wood. Sometimes varnish was also applied. Due to fluctuating levels of relative humidity and temperature, the wood swells and shrinks, causing the layers on top of the wood to become damaged. LÄS MER

  4. 3. Transient state UV spectroscopy of Tyrosine and Tyrosine-containing protein

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Hongjian Chen; [2023]
    Nyckelord :Tyrosine; Calmodulin; Autofluorescence; Transient-state monitoring; Electronic state transitions; Tyrosin; Calmodulin; Autofluorescens; Transient-tillståndsövervakning; Elektroniska tillståndsövergångar;

    Sammanfattning : The aromatic amino acids tryptophan, tyrosine, and phenylalanine have been extensively used for different label-free protein studies. These investigations extract information on protein conformations and interactions from the emitted fluorescence's intensity, wavelength, and/or polarization. LÄS MER

  5. 4. Developments Towards High-Resolution Muonic Atom X-ray Spectroscopy of Low-Z Elements : For precision measurements of absolute nuclear charge radii

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Högenergifysik

    Författare :Benjamin Verbeek; [2023]
    Nyckelord :muon physics; subatomic physics; charge radius; nucleus; lithium; silicon drift detector; microcalorimeter;

    Sammanfattning : This Master's thesis investigates a method to measure atomic nuclei with record precision using muonic atom X-ray spectroscopy. In particular, 6Li is measured experimentally. The method used is independent from the previous most precise measurement of the 6Li nuclear charge radius which uses electron scattering. LÄS MER

  7. 5. Historical mining of Fe-Ca ore in Garpenberg, Sweden. : A study based on lake sediment geochemistry from Finnhytte-dammsjön.

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Morgan Eliasson; [2023]
    Nyckelord :Paleolimnology; Lake sediment; XRF; Garpenberg; Mining history;

    Sammanfattning : It is well established that mining and metallurgy on a larger scale in Sweden originated in Bergslagen. The historical mining district Garpenberg in Bergslagen presently show the oldest signs of mining in Sweden (2300 BP) based on a study of a lake sediment profile from Gruvsjön. LÄS MER
