  1. 21. Determination and control of some pollutants in indoor environments

    Författare :Pawel Markowicz; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; indoor air quality; indoor pollutants; dampness; purification; tobacco smoke;

    Sammanfattning : Unsatisfactory indoor air quality (IAQ) may result from polluting emissions that are spread from building materials such as volatile organic compounds (VOCs) and/or microbial components or from various kinds of human activity such as smoking. Different methods are available to limit the exposure to unwanted pollutants and improve human wellbeing and health. LÄS MER

  3. 22. Fatal Residential Fires : Prevention and Response

    Författare :Marcus Runefors; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Residential fires; Fatal fires; Fire services; Fire fatalities; Emergency services; Smoke alarms; Sprinkler system; Prevention; Response;

    Sammanfattning : Fatal fires in residential occupancies show a decreasing trend over time, but are still responsible for takingapproximately 90 lives in Sweden each year. Much is known about the victims, but less is known about how thesedeaths can be prevented. LÄS MER

  4. 23. Volatile Hydrocarbons in Ambient Air. Gas Chromatographic Assessment, Emissions and Human Exposure

    Författare :Gunnar Barrefors; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; adsorbent sampling; 1; gas chromatography; biomass burning; Benzene; ethene; vehicle emissions; urban air; tobacco smoke; 3-butadiene;

    Sammanfattning : Hydrocarbons in ambient air constitute a potential health risk for a large number of individuals. The work reported in this thesis focusses on human exposure to volatile hydrocarbons in ambient air. The analytical determinations were made by adsorbent sampling followed by thermal desorption and gas chromatography. LÄS MER

  5. 24. Rocket-borne in situ measurements in the middle atmosphere

    Författare :Jonas Hedin; Jörg Gumbel; Markus Rapp; Ove Havnes; Stockholms universitet; []
    Nyckelord :rocket measurements; noctilucent clouds; meteoric smoke; nightglow; mesosphere; aerodynamics; NATURAL SCIENCES; NATURVETENSKAP; atmosfärvetenskap; Atmospheric Sciences;

    Sammanfattning : The Earth's mesosphere and lower thermosphere in the altitude range 50-130 km is a fascinating part of our atmosphere. Complex interactions between radiative, dynamical, microphysical and chemical processes give rise to several prominent phenomena, many of those centred around the mesopause region (80-100 km).

  7. 25. Measurement of T1 relaxation time in lungs - Preclinical and clinical MRI applications to COPD

    Författare :Daniel Alamidi; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic Resonance Imaging; biomarker; tobacco smoke; mouse; smoking; lung imaging; Chronic Obstructive Pulmonary Disease; ultrashort echo time UTE ; T1 mapping; longitudinal relaxation time;

    Sammanfattning : Monitoring of regional lung function in clinical trials of chronic obstructive pulmonary disease (COPD) requires alternative endpoints beyond global pulmonary function tests (PFTs), which is the most common approach for diagnosing lung function abnormalities in humans. A promising magnetic resonance imaging (MRI) biomarker of lung disease in humans and animals is the T1 relaxation parameter. LÄS MER
