  1. 1. Biological effects of high energy radiation and ultra high dose rates

    Författare :Björn Zackrisson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiobiology; 50 MV x-rays; 50 MeV electrons; in vitro; in vivo; RBE; OER; ultra high dose-rate; radiobiological models; model selection; models of stochastic processes;

    Sammanfattning : Recently a powerful electron accelerator, 50 MeV race-track microtron, has been taken into clinical use. This gives the opportunity to treat patients with higher x-ray and electron energies than before. Furthermore, treatments can be performed were the entire fractional dose can be delivered in parts of a second. LÄS MER

  3. 2. In vivo protein synthesis determinations in human immune cells

    Författare :Anna Januszkiewicz; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Intact immune responses are essential for defeating severe infections in individual patients. Insufficient function of the immune system contributes to a poor prognosis in these patients, in particular the ICU patients. Nevertheless, the immune system function is not easily monitored and evaluated. LÄS MER

  4. 3. On the Implementation of Integer and Non-Integer Sampling Rate Conversion

    Författare :Muhammad Abbas; Håkan Johansson; Oscar Gustafsson; Vassilis Paliouras; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The main focus in this thesis is on the aspects related to the implementation of integer and non-integer sampling rate conversion (SRC). SRC is used in many communication and signal processing applications where two signals or systems having different sampling rates need to be interconnected. LÄS MER

  5. 4. Studies on the regulation of human skeletal muscle lipolysis in vivo

    Författare :Veronica Quisth; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Intramuscular triglycerides; skeletal muscle; lipolysis; insulin; catecholamines; microdialysis;

    Sammanfattning : Intramuscular triglyceride deposits are a significant energy source, and are considered to be of importance in the pathogenesis of skeletal muscle insulin resistance. In contrast to adipose tissue, the lipolytic process in skeletal muscle is not well characterised. LÄS MER

  7. 5. Processes of Magma-crust Interaction : Insights from Geochemistry and Experimental Petrology

    Författare :Frances M Deegan; Valentin R Troll; Luigi Dallai; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Canary Island magmatism; HP-HT experimental petrology; magma-crust interaction; Merapi volcano; radiogenic isotopes Sr; Nd; Pb ; stable isotopes O; B .; Solid earth geology and petrology; Berggrundsgeologi och petrologi; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

    Sammanfattning : This work focuses on crustal interaction in magmatic systems, drawing on experimental petrology and elemental and isotope geochemistry. Various magma-chamber processes such as magma-mixing, fractional crystallisation and magma-crust interaction are explored throughout the papers comprising the thesis. LÄS MER
