  1. 1. Organophosphates and phthalates in air and dust from indoor environments : Method development and applied measurements

    Författare :Caroline Bergh; Conny Östman; Peter Haglund; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organophosphate esters; phthalate esters; air; dust; sampling; method development; GC MS; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Sammanfattning : Organophosphate and phthalate esters are polymer additives that are frequently found in air and dust in indoor environments. This thesis describes the development and application of air sampling and selective mass spectrometric (MS) determination of these two compound groups. LÄS MER

    Sammanfattning : Natural ventilation is the dominating ventilation process in ancient buildings like churches, and also in most domestic buildings in Sweden and in the rest of the world. These buildings are naturally ventilated via air infiltration and airing. LÄS MER

  4. 3. Aircraft Design Automation and Subscale Testing : With Special Reference to Micro Air Vehicles

    Författare :David Lundström; Petter Krus; Jean- Marc Moschetta; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This dissertation concerns how design automation as well as rapid prototyping and testing of subscale prototypes can support aircraft design. A framework for design automation has been developed and is applied specifically to Micro Air Vehicles (MAV). LÄS MER

  5. 4. Health effects of air pollution in Iceland : respiratory health in volcanic environments

    Författare :Hanne Krage Carlsen; Anna Oudin; Thorarinn Gislason; Kadri Meister; Bertil Forsberg; Gunilla Wieslander; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Respiratory health; air pollution; volcanic ash; epidemiology; hydrogen sulfide.; Epidemiology; epidemiologi; folkhälsa; Public health;

    Sammanfattning : Air pollution has adverse effects on human health. The respiratory system is the most exposed and short-term changes in air pollution levels have been associated with worsening of asthma symptoms and increased rates of heart attacks and stroke. Air pollution in cities due to traffic is the major concern, as many people are exposed. LÄS MER

  7. 5. Biological and air monitoring of exposure to isocyanates

    Författare :Carl Johan Sennbro; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; industrial medicine; Occupational health; asthma; protein adducts; polyurethane; biomarkers; occupational exposure; DBA; ICA; NDI; MDI; TDI; Diisocyanates; Isocyanates; Biomonitoring; Air monitoring; arbetsmiljömedicin; Yrkesmedicin;

    Sammanfattning : Exposure to isocyanates may induce disorders in the airways of workers. Therefore, application, development and validation of methods for exposure assessment is of great importance. LÄS MER
