  1. 1. Process Models for CO2 Migration and Leakage : Gas Transport, Pore-Scale Displacement and Effects of Impurities

    Författare :Farzad Basirat; Auli Niemi; Karsten Jensen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geological Carbon Storage; CO2 leakage; Field experiment; Laboratory experiment design; Multi-phase flow; Heterogeneity; Wettability; Pore-scale modeling; Impurity gases; Hydrology; Hydrologi;

    Sammanfattning : Geological Carbon Storage (GCS) is considered as one of the key techniques to reduce the rate of atmospheric emissions of CO2 and thereby to contribute to controlling the global warming. A successful application of a GCS project requires the capability of the formation to trap CO2 for a long term. LÄS MER

  3. 2. Experimental and Modelling Studies on the Spreading of Non-Aqueous Phase Liquids in Heterogeneous Media

    Författare :Fritjof Fagerlund; Auli Niemi; Tissa Illangasekare; Karsten Jensen; Uppsala universitet; []
    Nyckelord :Hydrology; NAPL; Multi-phase flow; Modelling; Experiment design; Heterogeneity; Constitutive relations; Multi-constituent contaminants; Capillary pressure; Relative permeability; Hysteresis; Hydrologi;

    Sammanfattning : Non-Aqueous Phase Liquids (NAPLs) include commonly occurring organic contaminants such as gasoline, diesel fuel and chlorinated solvents. When released to subsurface environments their spreading is a complex process of multi-component, multi-phase flow. LÄS MER

  4. 3. Values, Norms & Ideology in Mainstream Economics

    Författare :Gert Helgesson; Karsten Klint Jensen; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Philosophy; economics; efficiency; equilibrium; extrascientific; ideology; ideologically relevant; implicit; intrascientific; model; neoclassical; norm; preference; stability; valuation; value-free; Filosofi; Philosophy subjects; Filosofiämnen; Practical Philosophy; praktisk filosofi;

    Sammanfattning : Is economics a value-free science? Defenders of the view that it is admit that there have been failures to keep valuations and norms out but claim that economics is nevertheless essentially value-free. Critics, on the other hand, claim that economics is not and cannot be value-free. LÄS MER

  5. 4. Better safe than sorry: : Applying philosophical methods to the debate on risk and the precautionary principle

    Författare :Per Sandin; Sven Ove Hansson; Karsten Klint Jensen; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; Philosophy; conceptual analysis; precautionary pronciple; precaution; risk; risk management; Filosofi; Philosophy subjects; Filosofiämnen;

    Sammanfattning : The purpose of the present thesis is to apply philosophical methods to the ongoing debate of the precautionary principle, in order to illuminate this debate. The thesis consists of an Introduction and five papers. Paper I con-cerns an objection to the method of conceptual analysis, the Charge from Psychology. LÄS MER
