  1. 1. Measurement of trace components in aqueous solutions with near and mid infrared Fourier transform spectroscopy

    Författare :Peter Snoer Jensen; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Near-infrared; Temperature dependency; Dual-beam; Optical null; Optimal pathlength Haemodialysis liquid; Urea; Glucose; Phosphate; Atom- och molekylärfysik; Atomic and molecular physics; Infrared; Water absorption; Fourier transform spectroscopy; Fysicumarkivet A:2003:Snoer Jensen;

    Sammanfattning : This thesis treats various aspects of the measurement of trace components in aqueous solutions with Fourier transform infrared spectroscopy. This technique has several applications from such diverse fields as dairy industry and biomedical optics. LÄS MER

  3. 2. Roles of hematopoietin and cytokine tyrosine kinase receptors in early lymphopoiesis

    Författare :Christina Jensen; Stamcellscentrum (SCC); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; IL -7; FLT3 Ligand; cytokines; lymphopoiesis; hematopoiesis; TSLP; apoptosis;

    Sammanfattning : Cytokines have been shown to have important roles in lymphopoiesis. However, many questions remain unresolved. Among other, while the action of interleukin (IL)-7 in alpha beta T cell development in mouse seems to be largely mediated through permissive survival signaling, the possible permissive role of IL-7 in early B cell development is disputed.

  4. 3. Geophysical tools for prognosis of deformation in hardrock environments

    Författare :Mai-Britt Mose Jensen; Satu Mertanen; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; AMS; Bergmekanik; Refleksions seismik; Gravimetri; Petrofysik; Tillämpad geofysik; Applied Geophysics;

    Sammanfattning : Underground mining of the Kiirunavaara iron mineralization is causing large-scale deformation of the hangingwall of the orebody. To understand and possibly predict future deformation, a structural model of the hanging wall and a good understanding of the petrophysical and mechanical properties of the constituent rocks is necessary.

  5. 4. Miljöinvesteringar i svensk transportnäring : Drivkrafter och strategier

    Författare :Janni Jensen (Nilsson); Olof Hjelm; Magnus Blinge; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Miljö; miljöinvesteringar; investeringar; investeringskalkyler; transporter; godstransporter; strategier; Business studies; Företagsekonomi;

    Sammanfattning : The environmental work in the Swedish transportation business was not very prioritized during the period up until 1990. If any environmental work occurred at all, it often entailed only necessary measures to meet the demands of environmental law.All this changed almost over night roundabout 1990. LÄS MER

  7. 5. 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
