  2. 1. On mechanisms controlling air-sea gas exchange

    Author : Lucía Gutiérrez-Loza; Anna Rutgersson; Erik Sahlée; Marcus B. Wallin; Tom Bell; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Air-sea gas exchange; eddy covariance; gas transfer velocity; Baltic Sea; Meteorologi; Meteorology;

    Abstract : Carbon is essential to the Earth’s system functioning, playing a major role in physical and biogeochemical processes in the atmosphere, the terrestrial biosphere, and the oceans. The concentration of carbon-based greenhouse gases in the atmosphere, such as carbon dioxide (CO2) and methane (CH4), has been increasing since the industrial era. READ MORE

  4. 2. Aerosol Measurements as Applied for Exposure Characterization

    Author : Andreas Dahl; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railroad; indoor air; environment; occupational health; exposure; isocyanate; airborne particles; station; traffic;

    Abstract : It is important to decrease the burden of disease. This is in part achieved by decreasing risks. The aim of this thesis is to provide a methodology for the characterization of aerosol exposure, which may lead to negative health effects. READ MORE

  5. 3. Biofiltration of odorous gas emissions

    Author : Anneli Andersson-Chan; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : Biofiltration has shown its potential as an interesting treatment alternative for contaminated gas streams. Unlike conventional technologies, such as adsorption, scrubbers, and incineration, biofiltration offers effective pollution control at relatively low capital and operating costs, and without the generation of secondary pollution that may require subsequent treatment.

  6. 4. Gas phase molecular relaxation probed by synchrotron radiation experiments

    Author : Jaume Rius i Riu; KTH; []
    Keywords : Molecular relaxation; synchrotron radiation; dispersed fluorescence; photoelectron spectroscopy; energy resolved electron ion coincidence technique;

    Abstract : This thesis presents experimental studies of gas phasemolecular relaxation after excitation with synchrotron photonsin the 15-35 eV and in the 70-350 eV regions.In the 15-35 eV region, molecular relaxation by neutraldissociation processes and nonFranck-Condon effects in N2 and O2 molecules have beenstudied by means of dispersed fluorescence and photoelectronspectroscopy experimental techniques, respectively.

    Abstract : This thesis presents HELIOS, an in-house laboratory for time-resolved pump-probe spectroscopy with extreme-ultraviolet (XUV) probe radiation. A wide span of pump wavelengths can be generated using commercial laser equipment while XUV probe radiation is generated via a high harmonic generation process in a noble gas delivering probe photons with energies between 20 eV and 72 eV.
