  3. 2. Bioassay Development for Identification of Cyclooxygenase-2 Inhibitors of Natural Origin

    Författare :Therese Ringbom; Angelika Vollmar; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacognosy; Farmakognosi; Pharmacognosy; Farmakognosi; Pharmacognosy; farmakognosi;

    Sammanfattning : To examine cyclooxygenase-2 (COX-2) inhibitory effects of natural compounds and structurally related compounds, a radiochemical assay for measuring inhibition of COX-2 and COX-1 catalysed prostaglandin biosynthesis was optimised. That process resulted in the development of a reliable assay for finding COX-2 inhibitors in plants, and for investigating plant constituents pertaining to the inhibition of COX-2 and COX-1. LÄS MER

  4. 3. Surface Coatings as Xenon Diffusion Barriers for Improved Detection of Clandestine Nuclear Explosions

    Författare :Lisa Bläckberg; Mattias Klintenberg; Henrik Sjöstrand; Anders Ringbom; Kai Vetter; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Radioxenon; Gas Diffusion Barrier; Plastic Scintillator; Comprehensive Nuclear-Test-Ban Treaty; Atomic Layer Deposition; Al2O3; Molecular Dynamics; Light Transport;

    Sammanfattning : This thesis investigates surface coatings as xenon diffusion barriers on plastic scintillators. The motivation for the work is improved radioxenon detection systems, used within the verification regime of the Comprehensive Nuclear-Test-Ban Treaty (CTBT).One type of radioxenon detection systems used in this context is the Swedish SAUNA system.

    Sammanfattning : This thesis investigates the ability of transparent surface coatings to reduce xenon diffusion into plastic scintillators. The motivation for the work is improved radioxenon monitoring equipment, used with in the framework of the verification regime of the Comprehensive Nuclear-Test-Ban Treaty. LÄS MER

  7. 5. Från Gotland till Estland : kyrkokonst och politik under 1200-talet

    Författare :Kersti Markus; Åsa Ringbom; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Gotland; Estonia; Scandinavia; Middle Ages; 13th century; Cistercian Order; Dominican Order; Mediaeval Church Architecture; The Masons Lodge; Liturgy; Crusade; Livonia; Denmark; Sweden; Art; Konstvetenskap; konstvetenskap; Art History;

    Sammanfattning : Churches in two Estonian counties - Ösel-Wiek and Jerwen - have very many similar features with churches in Gotland. In earlier scientific researches these similarities in styles were explained by the artistic ambitions of single travelling masons, the present research emphasizes the political and artistic preferences of those who ordered the buildings to be built and who financed them.
