  1. 6. Small-Scale Absorbed Dose Modelling in Selective Internal Radiation Therapy : Microsphere Distribution in Normal Liver Tissue

    Sammanfattning : Radioembolisation (RE), with yttrium-90 (90Y) labelled microspheres, is an increasingly common treatment method for unresectable liver tumours. The tolerable mean absorbed dose for normal liver (NL) tissue is higher in RE than in External Beam Radiation Therapy (EBRT); absorbed dose heterogeneity is thought to be one important reason, together with a low absorbed dose rate, but the knowledge of microsphere distributions is limited.

  3. 7. Microsphere-based modeling of electro-active polymers

    Författare :Sara Thylander; Hållfasthetslära; []
    Nyckelord :;

    Sammanfattning : Elektroaktiva polymerers (EAPs) främsta egenskap är deras förmåga att kunna omvandla elektrisk energi till mekanisk energi (och vice versa). Den typ av EAPs som behandlas inom ramen för detta arbete kallas för dielektriska elastomerer och är en undergrupp av elektroniska elektroaktiva polymerer. LÄS MER

  4. 8. Endothelium-derived substances and regional hemodynamics in experimental hypertension

    Författare :Sven-Olof Granstam; Uppsala universitet; []
    Nyckelord :Medical sciences; nitric oxide; endothelin; hypertension; rats; SHR; hemodynamics; blood pressure; blood flow; acetylcholine; carvedilol; microsphere method; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Sammanfattning : The spontaneously hypertensive rat (SHR), a model for experimental hypertension, is considered to have similarities with essential hypertension in humans. Differences between SHR and normotensive Wistar Kyoto rats (WKY) in the vascular response to endothelial-derived substances such as nitric oxide (NO) have been intensively studied in vitro. LÄS MER

    Sammanfattning : Schizophrenia is a group of disorders with a worldwide lifetime prevalence of 0.85%. Thefunctional outcome of the disorder seem stable from the first systematic outcome studies to thepresent day, and vary only with changes in diagnostic criteria. LÄS MER
