  2. 1. Innovative Bioreactors for the Degradation of Polycyclic Aromatic Hydrocarbons

    Author : Benoit Guieysse; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Bioteknik; Biotechnology; PAH; degradation; aromatic; contaminant; pollutant; bioreactor; organic pollutant; kontroll av utsläpp; Miljöteknik; pollution control;

    Abstract : The development of biological reactors for the treatment of toxic and recalcitrant organic pollutants is a complex task. Firstly, microbial inoculation, acclimation and selection must be optimized to provide the best microflora possible. READ MORE

  4. 2. Numerical study on flow and pollutant dispersion inside street canyons

    Author : Yang Yunkai; Martinac Ivo; Peng Shia-Hui; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flow; Pollutant dispersion; CFD; Street canyon; Reliability; SRA - Energy; SRA - Energi;

    Abstract : This thesis analyzes the characteristics of flow pattern and vehicle-emitted pollutant dispersion in roughness surface layer. In an urban environment, wind flow and transported-pollutant source interfere strongly with buildings and other roughness elements on the surface ground, which results in complex characteristics of flow pattern and pollutant dispersion in 3D circumstances.

    Abstract : Development and application of some laser techniques for the study of engine combustion are presented. The investigations mainly cover two aspects: fuel dynamics and formation of NO. READ MORE

  6. 4. The distribution of brown trout (Salmo trutta L.) in streams in southern Sweden

    Author : Anders Eklöv; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; growth; density; intraspecific competition; predation; cover; interspecific interaction; fish assemblage; pollutant; recolonization; Ecology; Ekologi;

    Abstract : This thesis examines the effect of water quality, habitat and species interactions on the occurrence and abundance of stream fishes in southern Sweden. I found that improvements in water quality between the 1960s and 1990s have led to recolonization of streams by brown trout (Salmo trutta L.), stone loach (Barbatula barbatula L. READ MORE

  7. 5. Sensitivity and Uncertainty Analysis Methods : with Applications to a Road Traffic Emission Model

    Author : Olle Eriksson; Stig Danielsson; Rolf Sundberg; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Emission; Grid; Model; Pollutant; Response surface; Road traffic; Sensitivity analysis; Simulation; Uncertainty analysis; Avgaser; Vägtrafik; Miljöaspekter; Statistics; Statistik;

    Abstract : There is always a need to study the properties of complex input–output systems, properties that may be very difficult to determine. Two such properties are the output’s sensitivity to changes in the inputs and the output’s uncertainty if the inputs are uncertain. READ MORE
