  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. Mildly nutritious or mild and nutritious : a study on the effect of low phenolic content in wheat and rye kernels and its sensory effect on whole grain breads

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Julia Kullberg; [2023]
    Nyckelord :White rye; white wheat; low phenolic flour;

    Sammanfattning : Recent studies on the dietary habits of the Swedish population show that only 30% reaches the recommended levels of dietary fibres. As a high fiber intake is associated with health benefits and a decrease in the risk of developing lifestyle disease, there may be a need for new types of fibre and wholegrain products. LÄS MER

  4. 3. THE GOTHENBURG COLOURISTS - Analysis of selected works by Karin Parrow, Ivan Ivarsson and Ragnar Sandberg

    Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Sebastian Karlsson; [2022-11-28]
    Nyckelord :Gothenburg; colourists; pigment; analysis; Göteborg; Kolorister; Karin Parrow; Ivan Ivarsson; Ragnar Sandberg;

    Sammanfattning : ABSTRACT Paintings from three selected Gothenburg colorists, Karin Parrow, Ivan Ivarsson and Ragnar Sandberg were analysed to gain insight into their use of colour. The Gothenburg colorists refers to a group of artists who were active in the Gothenburg area and west coast of Sweden, most of them had studied under Tor Bjurström (1888-1966) at the Valand Academy of art during the 20s.

  5. 4. DELAMINATING PAINT IN AN 18TH CENTURY CANVAS WALL PAINTING A Case Study at the von Echstedt Manor

    Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Lisa Bandgren; [2021-10-28]
    Nyckelord :Delaminating Paint; Canvas Wall Paintings; Material Analysis;

    Sammanfattning : This study investigates the cause and progression of the ongoing deterioration in a canvas wall painting from the 1760s in the Green Chamber at the von Echstedt manor. In an area approximately 170 x 170 cm on the south wall, the paint is severely delaminating despite several attempt to consolidate it. LÄS MER

  7. 5. Application of data-driven models in exploring cyanobacterial bloom risks in Lake Mälaren

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Abigail Huertas Herrera; [2021]
    Nyckelord :Random Forest; blue-green algae; WHO Alert Level Framework; drinking water supply; cyanobacterial blooms;

    Sammanfattning : Cyanobacteria are a unique organism, a bacterium that develop photosynthesis, thus it contains chlorophyll, a pigment commonly associated to algae. For this reason, cyanobacteria are also known as blue-green algae. One of the secondary metabolites of cyanobacteria is cyanotoxin, a substance which is hepatoxic, neurotoxic, and dermatoxic. LÄS MER
