  1. 1. Modeling internal deformation of salt structures targeted for radioactive waste disposal

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Zurab Chemia; Hemin Koyi; Harro Schmeling; Ian Alsop; [2008]
    Keywords : salt; diapir; anhydrite; deformation; entrainment; numerical modeling; rheology; sinking; Gorleben;

    Abstract : This thesis uses results of systematic numerical models to argue that externally inactive salt structures, which are potential targets for radioactive waste disposal, might be internally active due to the presence of dense layers or blocks within a salt layer.The three papers that support this thesis use the Gorleben salt diapir (NW Germany), which was targeted as a future final repository for high-grade radioactive waste, as a general guideline.

  2. 2. Mechanisms of salt frost scaling on portland cement-bound materials: studies and hypothesis

    University dissertation from Division of Building Materials, LTH, Lund University

    Author : Sture Lindmark; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deterioration; Durability; Freeze-Thaw; Frost; Salt; Mechanism; Chloride; Diffusion; Adsorption; Building construction; Cement; Concrete; Byggnadsteknik;

    Abstract : A hypothesis regarding the mechanism causing salt frost scaling on Portland cement-bound materials is described. It is assumed that deterioration is due to osmotic micro ice body growth, as has been previously proposed for frost deterioration of moisture-isolated specimens of cement-bound materials. READ MORE

  3. 3. Neutronics in Molten Salt Reactors

    University dissertation from Division of Building Materials, LTH, Lund University

    Author : Anders Jonsson; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; one-group theory; Green s function; two-group theory; Molten Salt Reactors; neutron noise;

    Abstract : This thesis contains two studies of the MSR properties. The firstuses one-group theory and data that correspond to a traditionaluranium fuelled light water reactor to investigate the basis physicaldifferences that might arise duesolely to the movement of the fuel. READ MORE

  5. 5. Genetic Factors and Dietary Salt Intake as Determinants of Blood Pressure and Risk of Primary Hypertension

    University dissertation from Medical Faculty, Lund University

    Author : Fredrik Wowern; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood Pressure; Kardiovaskulära systemet; Cardiovascular system; Genetics; Salt; Hypertension;

    Abstract : Blood pressure (BP) and development of hypertension (HT) are determined by both genetic and environmental factors. The specific genetic etiology of these two entities has remained enigmatic despite large efforts. In addition, daily salt intake seems to predispose for certain individuals to develop HT. READ MORE
