  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

  2. 2. Interaction Studies in Complex Fluids with Optical Biosensors

    Författare :Jenny Carlsson; Bo Liedberg; Kjell Janné; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Type 1 diabetes; Insulin; Lectin panel; Ellipsometry; Meat juice; Serum proteins; Chemistry; Kemi;

    Sammanfattning : In this thesis interactions in complex fluids, such as serum and meat juice, were analysed with optical biosensor techniques.Panels of lectins immobilised on gold surfaces were used for investigation of differences in protein glycosylation pattern in sera and meat juices between various species.

  3. 3. Gas Sensing Based on Ellipsometric Readout : Methodology and Development

    Författare :Guoliang Wang; Herbert Wonneester; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The concept of an ellipsometric sensor array system - "an optical nose" - is presented. The system is used to monitor and discriminate gases. The optical readout is based on polarizer-compensator-sample-analyzer (PCSA) off-null ellipsometry. LÄS MER

  4. 4. Stellar Models in General Relativity

    Författare :Lars Samuelsson; Kjell Rosquist; Brandon Carter; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; General relativity; compact objects; neutron stars; Physics; Fysik;

    Sammanfattning : Neutron stars are some of the most fascinating objects in Nature. Essentially all aspects of physics seems to be represented inside them. Their cores are likely to contain deconfined quarks, hyperons and other exotic phases of matter in which the strong interaction is the dominant force. LÄS MER

  5. 5. The megencephaly mouse : from gene to neuronal proliferation

    Författare :Ann-Sophie Persson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Megalencephaly; epilepsy; mouse model; genetics; voltage gated potassium channel; hippocampus; proliferation;

    Sammanfattning : Megalencephaly, enlarged brain, can be associated with a wide range of symptoms from benign to severe. Severe cases are often associated with mental retardation and seizures. The megencephaly mouse shows a dramatic, progressive increase in size of the hippocampus and ventral cortex. LÄS MER
