  1. 1. Characterisation of airborne particles from rail traffic

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Saeed Abbasi; KTH.; KTH.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; airborne; railway; brake; block; TECHNOLOGY Engineering mechanics Other engineering mechanics; TEKNIKVETENSKAP Teknisk mekanik Övrig teknisk mekanik; SRA - Transport; SRA - Transport; Järnvägsgruppen - Effektiva tågsystem för godstrafik; Järnvägsgruppen - Effektiva tågsystem för godstrafik; Järnvägsgruppen - Effektiva tågsystem för persontrafik; Järnvägsgruppen - Effektiva tågsystem för persontrafik; Järnvägsgruppen - Tribologi; The KTH Railway Group - Tribology;

    Sammanfattning : Since the investigation of wear particles in rail transport started in late-1910s, the high mass concentration of these particles has raised worries among researchers concerned with air quality. However, effective action has yet to be taken because of lack of relevant knowledge. LÄS MER

  2. 2. Towards elimination of airborne particles from rail traffic

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Saeed Abbasi; KTH.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Airborne; brake block; brake pad; railway; subway; TEI; wheel–rail; wear; Järnvägsgruppen - Tribologi; The KTH Railway Group - Tribology;

    Sammanfattning : Since the investigation of wear particles from rail transport started in the late 1910s, the high mass concentrations of these particles have prompted concern among researchers interested in air quality. However, effective action has yet to be taken because relevant knowledge is still missing. LÄS MER

  4. 4. A study of airborne wear particles from automotive disc brakes

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Jens Wahlström; KTH.; [2011]
    Nyckelord :Disc brakes; Airborne wear particles; Nanoparticles; Cellular automaton; TECHNOLOGY Other technology Mechanical engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Maskinteknik;

    Sammanfattning : During braking, both the disc and pads in disc brakes are worn. Since disc brakes are not sealed,some of the wear particles generated can become airborne. LÄS MER

  5. 5. Particulate airborne impurities

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Kai Wilkinson; Sveriges lantbruksuniversitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The cumulative effects of air pollutants are of principal concern in research on environmental protection in Sweden. Post-industrial society has imposed many limits on emitted air pollutants, yet the number of reports on the negative effects from them is increasing, largely due to human activity in the form of industrial emissions and increased traffic flows.
