  1. 21. On Microvascular Inflammation and Intestinal Leakage in Radiation Enteropathy

    Författare :Andrada Röme; Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiation; colon; intestinal leakage; Leukocyte and platelet recruitment;

    Sammanfattning : Gastrointestinal tract damage is an insidious feature in patients undergoing radiotherapy. Microvascular inflammation, including leukocyte and platelet recruitment as well as epithelial barrier dysfunction, are considered to constitute key components in the pathophysiology of radiation-induced enteropathy.

  3. 22. Modelling late toxicity in hypofractionated radiation therapy

    Författare :Niclas Pettersson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hypofractionation; normal tissue complication probability; modelling; linear-quadratic model; fractionation sensitivity; late toxicity; radiation-induced rib fracture; genitourinary toxicity; stereotactic body radiation therapy; high-dose-rate brachytherapy; multimodality radiation therapy; patient-reported outcomes; prostate cancer; nsclc;

    Sammanfattning : In hypofractionated radiation therapy (RT), the treatment is delivered by few fractions with high doses per fraction. This is in contrast to conventionally fractionated RT where the total dose is delivered in many fractions with low doses per fraction. LÄS MER

  4. 23. Radiation induced corrosion of copper

    Författare :Åsa Björkbacka; Mats Jonsson; Christofer Leygraf; Mehran Mostafavi; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Corrosion; oxidation; copper; copper oxide; gamma radiation; radiolysis; hydrogen peroxide; hydroxyl radical; Kemi; Chemistry;

    Sammanfattning : The process of radiation induced corrosion of copper is not well understood. The most obvious situation where the knowledge of this process is crucial is in a deep repository for high level spent nuclear fuel where the fuel will be sealed inside copper canisters. LÄS MER

  5. 24. Characterization of oxy-fuel flames - their composition, temperature and radiation

    Författare :Klas Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion; O2 CO2; NO formation; Radiation; Oxy-fuel; Flame properties;

    Sammanfattning : Oxy-fuel combustion is receiving growing attention as one of the promising CO2 capture technologies in connection to power production. Yet, significant efforts are required in research and development of this combustion process in order to be able to design and optimize a full scale power plant. LÄS MER

  7. 25. Radiation tests of semiconductor detectors

    Författare :Valery Chmill; Bengt Lund-Jensen; Richar Brenner; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; radiation physics; materials science; Nuclear physics; Kärnfysik;

    Sammanfattning : This thesis investigates the response of Gallium Arsenide (GaAs) detectors to ionizing irradiation. Detectors based on π-υ junction formed by deep level centers doping. LÄS MER
