  1. 16. Constructed Wetlands and Deconstructed Discourses : Greenhouse gas fluxes and discourses on purifying capacities

    Författare :Elisabeth Johansson; Bo Svensson; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; växthuseffekter; vattenrening; miljöaspekter; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : This thesis is a study within the sciences ofconstructed wetlands. It has two sections. Section one is a natural scienrific study ofgas fluxes from construcred wetlands and section two is an analysis ofhow natural sciences describe constructed wetlands. LÄS MER

  3. 17. Life Cycle Impacts of Road Infrastructure : Assessment of energy use and greenhouse gas emissions

    Författare :Sofiia Miliutenko; Anna Björklund; Robert Karlsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cumulative Energy Demand CED ; Global Warming Potential GWP ; Life Cycle Assessment LCA ; road infrastructure; strategic planning;

    Sammanfattning : Road infrastructure is essential in the development of human society, but has both negative and positive impacts. Large amounts of money and natural resources are spent each year on its construction, operation and maintenance. Obviously, there is potentially significantenvironmental impact associated with these activities. LÄS MER

  4. 18. Greenhouse Gas Reduction in Industry through Process Integration

    Författare :Helén Axelsson; Chalmers tekniska högskola; []

  5. 19. Carbon trace gas dynamics in subarctic lakes

    Författare :Joachim Jansen; Patrick Crill; Andreas Lorke; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lakes; methane; carbon dioxide; fluxes; gas transfer; proxy; climate change; geokemi; Geochemistry;

    Sammanfattning : Northern lakes are important sources of greenhouse gases carbon dioxide and methane to the atmosphere. Emissions are expected to increase as the climate continues to warm. Even so, lake carbon budgets are currently poorly constrained. This is in part because of a limited understanding of the processes that govern the flux. LÄS MER

  7. 20. Humidification Processes in Gas Turbine Cycles

    Författare :Marcus Thern; Kraftverksteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; applied thermodynamics; Thermal engineering; Energiforskning; Energy research; HAT; Biomass; Biofuel; Humidification; Evaporation; Evaporative gas turbine ; Humid air turbine ; Termisk teknik; termodynamik;

    Sammanfattning : The global climate change caused by emissions of greenhouse gases from combustion processes has been recognized as a continuously growing problem and much research focuses on improving the environmental performance of gas turbines. The potential of improving gas turbine component efficiencies has become smaller each decade and therefore, thermodynamic cycles have become more interesting for power producing units. LÄS MER
