    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.

    Sammanfattning : Arbetet har fokuserat på att minimera arbetsbelastningen för personalen hos företaget Arcoma. Detta har uppnåtts genom att bygga ett automatiserat mätsystem för läckstrålning med material som fanns hos Arcoma. LÄS MER

  4. 3. Study of Environmental Effects on Photo-MultiplierTubes for the X-ray Polarimetry Mission XL-Calibur

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Jonathan Karlsson; Sebastian Alveteg; [2021]
    Nyckelord :;

    Sammanfattning : XL-Calibur is a balloon-borne hard X-ray polarimetry mission with goals to analyze celestial objects too small and distant to be imaged. A crucial part of XL-Calibur is the anti-coincidence shield which through active collimation reduces unwanted hits when gathering data. LÄS MER

  5. 4. Evaluation of residual stresses and distorsions in additively manufactured components

    Master-uppsats, KTH/Hållfasthetslära (Avd.)

    Författare :Sonja Jonsson; Sebastian Krappedal; [2018]
    Nyckelord :Additive manufacturing; selective laser melting; inherent strain; distortions; residual stresses; X-ray di↵raction; Simufact Additive;

    Sammanfattning : Additive manufacturing is a novel manufacturing technique, which has developed rapidly in recent years. The additive manufacturing process produces complex geometries, light weighted components and reduces the material waste. During the building process, a laser energy source is commonly used to melt the metal powder. LÄS MER

  7. 5. Synthetic bone grafts for treatment of femoral head necrosis

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Oorganisk kemi

    Författare :Sebastian Borg; [2017]
    Nyckelord :;

    Sammanfattning : Necrosis of the femoral head is a relatively common medical condition that radically decrease the quality of life for the patient. Left untreated it could lead to destruction of the hip joint. A common treatment is using bone autografts, also called bone chips. LÄS MER
