  1. 1. Exploring the effects of pressure on the magnetic properties of quasi-low dimensional quantum magnets via thermodynamic measurements

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

    Författare :Emelie Zhu; [2024]
    Nyckelord :Physics and Astronomy; Technology and Engineering;

    Sammanfattning : Four model solid state compounds were used to experimentally investigate the effects of pressure on the interactions in one- and two-dimensional Heisenberg magnetic models. BaCuSi2O6, BaCu2V2O8, SrCuO2 and CuGeO3 were successfully synthesized via solid-state reactions and characterized via x-ray diffraction. LÄS MER

  3. 2. APPLICATION OF IN SITU Rb-Sr DATING AND GEOCHEMICAL INVESTIGATIONS ON A NEW, 1.52-1.56 GA. OLD PEGMATITE FIELD IN THE ARCHIPELAGO OFF GOTHENBURG, IDEFJORDEN TERRANE, WESTERN SWEDEN

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Laszlo Zorc; [2023-08-18]
    Nyckelord :;

    Sammanfattning : In this study, Rb-Sr geochronology was used to determine the crystallization/cooling ages of muscovites and biotites from mapped primitive barren and rare element pegmatites in the Stora-Le-Marstrand Formation in the southwestern archipelago of Gothenburg. The results indicate that primitive barrens can be linked to the DG2 deformation event that occurred 1. LÄS MER

  4. 3. Comparison of properties on Orally Disintegrating Tablets (ODTs) produced by direct compression or fluid bed granulation

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Julia Ahlbom; [2023]
    Nyckelord :Orally disintegrating tablet; fluid bed granulation; disintegration time; pharmaceutical technology; Technology and Engineering;

    Sammanfattning : Orally disintegrating tablets (ODTs) is a popular drug delivery system as they dissolve in the mouth, usually within seconds which enables easy medication for patients with problem swallowing. In this thesis properties of ODTs were compared when produced with direct compression of the excipients or the excipients were pretreated to form granules in a fluid bed granulator prior to tableting.

  5. 4. Veni, Vidi, Vendidi : En analys av asen i norr till denaren i söder

    Master-uppsats, Uppsala universitet/Arkeologi

    Författare :Denise Lundgren; [2023]
    Nyckelord :Central places; Gudme; Uppåkra; Stray coins; Roman coins; Scandinavia; Roman Empire; Iron Age; Centralplats; Gudme; Uppåkra; Utmarksfynd; Romerska mynt; Skandinavien; Romerska riket; Järnåldern;

    Sammanfattning : The presence of roman coins outside of the Roman Empire during the Iron Age is a curiousthing. One would assume they represent a giant trade confederation of sorts, and one would notbe completely wrong in assuming so. The trade aspect of the Roman Empire to the north is stillsomething unknown.

  7. 5. Syn-Magmatic Deformation Structures in the Slaufrudalur Pluton, East Iceland

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Chun Hei Ho; [2023]
    Nyckelord :Granite; Iceland; magma chamber; magmatic microstructure; melt fraction; mush; pluton; rheology; strain; syn-magmatic deformation;

    Sammanfattning : Structures and deformation mechanisms of magmatic rocks are controlled by rheology. An increase in melt fraction can weaken a rock body and localises significant amount of strain. This interplay between rheology, melting and deformation in a magma reservoir, however, is not always clearly documented in literature. LÄS MER
