  1. 1. Extraction of PCBs from Sediments: Towards Bioavailability Assessment Based on Supercritical Fluid Extraction

    Författare :Tobias Nilsson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytisk kemi; Analytical chemistry; Bioavailability; PCB; SFE;

    Sammanfattning : Persistent organic pollutants (POPs) pose serious threats to our global environment. These compounds have high chemical and biological stability and they are also very lipophilic. LÄS MER

  5. 4. Measuring and modelling variations in the distribution of atmospheric water vapour using GPS

    Författare :Tobias Nilsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Global Positioning System GPS ; Microwave Radiometry; Water Vapour; Climate; Atmospheric Turbulence;

    Sammanfattning : Turbulence introduce variations in the refractive index of air, which in turn result in fluctuations in the phase and amplitude of radio signals propagating through the atmosphere. Most important are the variations due to fluctuations in the water vapour field. LÄS MER

  7. 5. Protein and lipid interactions within the respiratory chain : Studies using membrane-mimetic systems

    Författare :Tobias Nilsson; Peter Brzezinski; Petra Hellwig; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cytochrome c oxidase; ATP synthase; Bioenergetics; membrane-mimetics; Rcf1; liposomes; oxidative phosphorylation; lipids; protein-protein interactions; Biochemistry; biokemi;

    Sammanfattning : Energy conversion from nutrients to ATP is a vital process in cells. The process, called oxidative phosphorylation (OXPHOS) is performed by a combination of membrane-bound proteins. These proteins have been studied in great detail in the past, however much is still unknown about how they interact with each other. LÄS MER
