  2. 1. Characterisation of pollutants in stormwater treatment facilities

    Author : Kristin Karlsson; Davis Butler; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : The overall objective of this thesis is to increase the knowledge of both the pollutants within stormwater treatment facilities and the maintenance of these facilities. This objective has been achieved by studying water and sediment with respect to metal concentrations, fractionation, and toxicity from ponds, sedimentation tanks, and gully pots with different catchment characteristics as well as from the sediment removal process.

  4. 2. Fluid Dynamics in Stirred Vessels - Experiments and simulations of single-phase and liquid-liquid systems

    Author : Fredrik Svensson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Particle Image Velocimetry PIV ; single-phase; Laser Doppler Anemometry LDA ; mixing; liquid-Liquid; immiscible; stirred tank; Rushton turbine; Computational Fluid Dynamics CFD ; macro-instability; frequency analysis; refraction index matched;

    Abstract : This thesis applies experimental measurement techniques and computational fluid dynamics to evaluate turbulent mixing of liquid-liquid systems in stirred vessels. Also studies of macro-instabilities in a single-phase system and how they affect flow and thus mixing are conducted. READ MORE

  5. 3. Plasticity modelling of nickel based super alloy Alloy 718

    Author : Ted Sjöberg; Paul Åkerström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : The ever growing demand on reduced fuel consumption in modern aircrafts puts high requirements on manufacturers to reduce weight in all parts of the aircraft. With a total weight of up to one fifth of an aircraft’s total operating weight, ways to decrease the weight of the engine systems are continuously sought. READ MORE

  6. 4. Does fish health matter? The Utility of Biomarkers in Fish for Environmental Assessment

    Author : Niklas Hanson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biomarkers; Fish; Environmental monitoring; Ecological risk assessment; Rainbow trout; Perch;

    Abstract : Two common strategies to assess exposure to environmental toxicants are to measure chemical concentrations in the environment and to examine the presence of certain species that are known to be sensit... merive to pollution. READ MORE
