  1. 11. Computed Tomography of the Coronary Arteries : Developmental and Prognostic Investigations

    Författare :Mårten Sandstedt; Anders Persson; Joakim Alfredsson; Magnus Janzon; Jan Engvall; Mats Lidén; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Computed tomography (CT) is an increasingly used modality for investigations of patients with suspected coronary artery disease (CAD). Technical advances could improve diagnostic accuracy and lead to clinical workflow improvements. Also, more prognostic information can optimize clinical follow-up strategies and treatments. LÄS MER

  3. 12. Sustainable valorization of Biomass into Syngas/H2 via Biocarbon catalyst

    Författare :Hanmin Yang; Weihong Yang; Pär Jönsson; Linda Sandström; Chunfei Wu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrolysis; Catalytic upgrading; Biomass; Biochar; Syngas; Hydrogen; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : Environmental issues stemming from the rapid growth in global energy demand and carbon dioxide emissions require urgent resolutions. Biomass represents a viable alternative for displacing fossil fuels, as its energy can be converted into electricity, heat, fuels, and chemical precursors, thus substituting petrochemicals. LÄS MER

  4. 13. Renewable Heat on Demand : High-temperature thermal energy storage: a comprehensive study from material investigation to system analysis via innovative component design

    Författare :Silvia Trevisan; Björn Laumert; Rafael Guédez; Wujun Wang; Kurt Engelbrecht; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Technology;

    Sammanfattning : High-temperature thermal energy storage could enable widespread exploitation of renewable energy sources, providing the required energy flexibility. Technology and component development is needed to enhance the storage thermo-dynamic performance, and identify key design features. LÄS MER

  5. 14. Modelling Life Cycle Cost for Indoor Climate Systems

    Författare :Dennis Johansson; Institutionen för bygg- och miljöteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVAC; life cycle cost; energy; Energy research; Energiforskning; Byggnadsteknik; Building construction; indoor climate system; ventilation; maintenance; LCC;

    Sammanfattning : The indoor climate system, which serves a building with a proper indoor air quality and thermal comfort, has been predominantly designed based on the initial cost. A life cycle approach could improve both the economic and environmental performance since the energy use could decrease. LÄS MER

  7. 15. Biofiltration of odorous gas emissions

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

    Sammanfattning : 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.
