  2. 21. Oxidative Dissolution of Spent Fuel and Release of Nuclides from a Copper/Iron Canister : Model Developments and Applications

    Author : Longcheng Liu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model; oxidative dissolution; spent fuel; radiolysis; release; mass transport; radionuclide; hydrogen; corrosion; canister; near field; repository; Chemical engineering; Kemiteknik;

    Abstract : Three models have been developed and applied in the performance assessment of a final repository. They are based on accepted theories and experimental results for known and possible mechanisms that may dominate in the oxidative dissolution of spent fuel and the release of nuclides from a canister.

  4. 22. Tumour vasculature, oxygenation and radiosensitivity - a numerical modelling study

    Author : Jakob Heydorn Lagerlöf; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Angiogenesis; Dosimetry; Hypoxia; Modelling; Radionuclide therapy; Radiotherapy; Tumour Control Probability;

    Abstract : This thesis aims to investigate theoretically how parameters such as vessel density, blood oxygenation, blood velocity, spatial oxygen variation along vessels, tissue oxygen consumption and their distributions in uence the radiosensitivity of tumours. Numerical calculations are made in Matlab using voxel-based models. READ MORE

  5. 23. Turbulent transport in tokamak plasmas: linear-, quasi- and non-linear simulations

    Author : Emil Fransson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fusion – Plasma physics – Turbulent transport – Gyrofluid – Gyrokinetic;

    Abstract : An attractive energy source is nuclear fusion with its abundance of fuel, intrinsic safety and limited environmental impact. Although the concept of fusion energy was established in the 1920s, to develop fusion as an energy source has been challenging. READ MORE

  6. 24. Application of Laser-based Diagnostics to a Prototype Gas Turbine Burner at Selected Pressures

    Author : Ronald Whiddon; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; OH; Laser Diagnostics; Elevated Pressure; Syngas; DLE; NOx; Combustion; Gas Turbine; PIV; PLIF; Pilot; SGT-750; Fysicumarkivet A:2014:Whiddon;

    Abstract : The matured laser-diagnostic techniques of planar laser-induced fluorescence (PLIF) and particle image velocimetry (PIV) were applied to a prototype gas turbine burner operating on various fuels. The work was performed to provide verification of computational fluid dynamic (CFD) models of the combustion of atypical fuels in a gas turbine combustor. READ MORE

  7. 25. Non-equilibrium fermions within lattice density functional theory: quantum transport and ultracold-atom phenomena

    Author : Alexey Kartsev; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2013:Kartsev;

    Abstract : Cutting-edge technology needs small, ultrafast devices, operational in a wide range of regimes. This calls for solids with novel, unconventional and tailorable properties. Great progress is expected from materials in which electron-electron and electron-phonon correlations strongly affect the dynamics ( i.e. READ MORE
