  1. 1. Characterization of Aerosols Related to Occupational and Public Environments as Applied to Isocyanates and Road Wear

    Författare :Andreas Dahl; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The aim of this thesis was to characterize a personal denuder/filter sampler for isocyanate aerosol and to study the emission of airborne particles from the interaction between studded tires and pavements. Both types of aerosols are highly relevant for health studies in public and occupational environments. LÄS MER

  3. 2. Aerosol Measurements as Applied for Exposure Characterization

    Författare :Andreas Dahl; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railroad; indoor air; environment; occupational health; exposure; isocyanate; airborne particles; station; traffic;

    Sammanfattning : It is important to decrease the burden of disease. This is in part achieved by decreasing risks. The aim of this thesis is to provide a methodology for the characterization of aerosol exposure, which may lead to negative health effects. LÄS MER

  4. 3. Improved health economic assessments of sustainable transport solutions in urban environments

    Författare :Hedi Katre Kriit; Johan Nilsson Sommar; Joacim Rocklöv; Martin Andersson; Joel Schwartz; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; active commuting; electric vehicles; air pollution; particle matter; physical activity; morbidity; mortality; health economic evaluation; epidemiologi; Epidemiology; Public health; folkhälsa; sustainable development; hållbar utveckling;

    Sammanfattning : Introduction: Part of the European Strategy to achieve climate neutrality in the transport sector is to increase the proportion of electric vehicles (EVs) and active commuting. Health co-benefits from reduced air pollution and increased active commuting are assumed to follow; however, all dimensions of expected health effects are not quantified nor valued monetarily.

  5. 4. Tire Modeling and Friction Estimation

    Författare :Jacob Svendenius; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technological sciences; Vehicle Dynamics; Wheel Speed; Brush Model; Combined Slip; Tire Models; Teknik; Friction Estimation;

    Sammanfattning : New system technologies are continuously improving the performance of vehicles regarding comfort, stability, environmental stresses, and safety. Novel sensors are developed and used together with advanced control algorithms and faster and more accurate actuators to help the driver to maneuver the vehicle in a safer way. LÄS MER

  7. 5. Traffic related air pollution with emphasis on particle associated polycyclic aromatic hydrocarbons : Tire wear and biodiesel exhaust emissions

    Författare :Ioannis Sadiktsis; Roger Westerholm; Jan Andersson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical Chemistry; analytisk kemi;

    Sammanfattning : Particulate matter (PM) is regarded as one of the more important components of air pollution causing adverse health effects. A large group of compounds associated with PM are polycyclic aromatic compounds (PACs) which comprises polycyclic aromatic hydrocarbons (PAHs). LÄS MER
