  1. 21. Climate change mitigation through CDM : bioenergy technology and energy efficiency in the steel industry

    Författare :Chuan Wang; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Sammanfattning : Climate change is one of the most significant challenges to sustainable development facing the international community. Increased attention has been given by industries and governments from both industrialized and developing countries to reduce greenhouse gas (GHG) emissions through the clean development mechanism (CDM), one of the Kyoto Protocol's (KP) flexible mechanisms.

    Sammanfattning : Global renewable energy requirements rapidly increase with the transition to a fossil-free society. As a result, intermittent energy resources, such as wind- and solar power, have become increasingly popular. However, their energy production varies over time, both in the short- and long term.

  4. 23. Reducing Carbon Dioxide Emissions from the EU Power and Industry Sectors - An assessment of key technologies and measures

    Författare :Johan Rootzén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industry; carbon dioxide; cement; European Union; technologies; emission reductions; CCS; power; steel; CO2< sub>; refining; mitigation;

    Sammanfattning : In February 2011, the European Council reconfirmed the goal of reducing EU greenhouse gas emissions by at least 80% by 2050, as compared to the levels in 1990. The power and industrial sectors currently account for almost half of the total GHG emissions in the EU. LÄS MER

  5. 24. Microplastic Mitigation in Urban Stormwater : Assessing Horizontal-Flow Filters of Bark, Biochar and Sand as Remediation Strategies

    Författare :Gabriella Rullander; Sahar S. Dalahmeh; Roger Herbert; Jes Vollertsen; Claudia Lorenz; Ann-Margret Strömvall; Giuliano Di Baldassarre; Uppsala universitet; []

    Sammanfattning : Urban stormwater has been suggested as a significant vector through which microplastics (MPs) reach aquatic environments. Currently, only a small fraction of stormwater in Sweden undergoes any form of treatment. LÄS MER

  7. 25. Harmonic Mitigation in Traction Drives

    Författare :Hans Bängtsson; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydraulics; Mechanical engineering; converter; line interference; track circuit; Railway signalling system; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Sammanfattning : In railway traffic the low friction between wheel and rail causes long braking distances, normally much longer than the sight distance of the driver, i.e. if the driver starts the braking when a problem on the track is discovered, it might be too late to brake the train. Therefore, safe railway traffic can not only rely on the driver. LÄS MER
