    Sammanfattning : Objective: Pulmonary oedema is life threatening. A method is needed for reliable measurement of lung water in man in order to clarify aetiology, pathophysiology, prognosis, and to evaluate treatments against pulmonary oedema. LÄS MER

  3. 2. Atomic Scale Degradation of Zirconium Alloys for Nuclear Applications

    Författare :Gustav Sundell; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Irradiation damage; Hydrogen microanalysis; Hydrogen pick-up; Zirconium alloys; Atom probe tomography; Corrosion;

    Sammanfattning : Due to their low thermal neutron capture cross-section, zirconium alloys are widely used in the nuclear industry as fuel cladding and for structural components. The lifetime of the fuel assemblies in the reactors is primarily dictated by the ability of the cladding to withstand oxidation and hydrogen pick-up from the coolant water and radiation damage induced by the neutron flux.

  4. 3. Green Colloid Chemistry: Characterization of Environmentally Friendly Nonionic Surfactant Systems

    Författare :Christy Whiddon; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nucleophilic substitution; alkylglucosides; bicontinious micelles; self-diffusion NMR; nonionic surfactants; micellar catalysis; Physical chemistry; pKa; Fysikalisk kemi;

    Sammanfattning : Phase diagrams of mixed alkylglucoside surfactants, n-nonyl-b-D-glucopyranoside and n-decyl-b-D-glucopyranoside (C9G1 and C10G1) have been examined for the purpose of determining the microstructure surrounding a closed-loop miscibiliyt gap. There are large deuterium isotope effects on the phase diagram. LÄS MER

  5. 4. Experimental Studies in Chemical Physics

    Författare :Lars Karlsson; Michel Herman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; fysik;

    Sammanfattning : Different laser based methods have been applied for studying different aspects on chemical physics.The transition metal containing molecules vanadium oxide (VO), zirconium sulphide (ZrS), zirconium dimer (Zr2) and titanium dimer (Ti2) have been studied in cool molecular beams using two-photon ionization technique.

  7. 5. Control Mechanisms of Electron and Proton Transfer in Cytochrome c Oxidase

    Författare :Martin Karpefors; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Cytochrome c oxidase is a remarkable molecular machine that is bound in the inner mitochondrial membrane or in the cell membrane of bacteria. Using the free energy that is released when electrons from foodstuff are transferred to molecular oxygen, protons are translocated from the inner to the outer side of the membrane. LÄS MER
