  1. 11. Use of remote sensing and in situ observations of the atmosphere in chemical transport models

    Author : Emma Ward; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate; Air quality; Ground based observations; Satellite observations; Chemical transport modelling;

    Abstract : Measuring and simulating atmospheric chemical compositions helps us to better understand the impact from long-range transport of different pollutants. Aerosols and tropospheric ozone are examples of pollutants with life times long enough to get transported between continents. READ MORE

  3. 13. Element transport in marine coastal ecosystems – modelling general and element-specific mechanisms

    Author : Lena Konovalenko; Clare Bradshaw; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Modelling; bioaccumulation; concentration ratio; radionuclides; marine foodweb.; Marine Ecology; marin ekologi;

    Abstract : Understanding the behaviour of naturally-occurring and anthropogenically-derived radionuclides (isotopes) in the marine environment is important, because there is a need for their effective utilization either as in situ tracers or for industry, medical applications, the planning of waste-disposal facilities, and estimations of human and animal health risks. Radionuclides generally have the same chemical properties as their stable element analogues and thus show similar environmental behaviour and cycling to their stable counterparts. READ MORE

  4. 14. Pyrolysis of biomass in fluidized-beds: in-situ formation of products and their applications for ironmaking

    Author : Pelle Mellin; Weihong Yang; Blasiak Wlodzimierz; Gerrit Brem; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; Pyrolysis; Fluidized bed; CFD; Blast furnace; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : The iron and steel industry emitted 8 % of all CO2 emissions in Sweden, 2011. Investigating alternative energy carriers is the purpose of this thesis. By pyrolyzing biomass, an energetic solid, gaseous and liquid (bio oil) fraction is obtained. READ MORE

  5. 15. Development of Multi-Dimensional Laser Techniques for In-situ Combustion Diagnostics

    Author : Jenny Nygren; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Laser Diagnsotics; Visualisation; Laser technology; Laserteknik; Motors and propulsion systems; Motorer; framdrivningssystem; Combustion; Temperature; Fysicumarkivet A:2003:Nygren;

    Abstract : Multi-dimensional, laser-based measurements of quantities important for obtaining a better understanding of combustion processes, particularly of temperature and of species distributions, were performed using laser-induced fluorescence (LIF). The main purpose of the temperature experiments was to investigate the potential of employing a two-line atomic fluorescence technique (TLAF), using indium as the tracer species, in sooting environments such as in diesel engines.
