  2. 2. Spread of smoke and fire gases via the ventilation system

    Detta är en avhandling från Division of Building Science, Lund University

    Författare :Polina Gordonova; [1997]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compartment fires; fire flow; fire pressure; fire simulation; smoke spread; ventilation ducts; brandteknik; brand; brandspridning; rökspridning; ventilation; ventilationskanaler; beräkningsmodeller; datorprogram; simulering; teori;

    Sammanfattning : This thesis examines the problem of smoke spread via ventilation ducts to adjacent room(s) in case of a compartment fire. The main goal is to examine the possibility of operating the fans during different fires in four types of buildings (compartments, hospitals, offices and hotels) and to estimate the risk of smoke spread in different conditions..

  3. 3. Meteoric Aerosols in the Middle Atmosphere

    Detta är en avhandling från Stockholm : Meteorologiska institutionen (MISU)

    Författare :Linda Megner; Stockholms universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; meteoroid; meteor; nucleation; mesosphere; stratosphere; ablation; smoke; NLC; PMSE; PSC; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap; atmosfärvetenskap; Atmospheric Sciences;

    Sammanfattning : This thesis concerns the fate of the meteoric smoke in the Middle Atmosphere, and its effect on ice phenomena such as noctilucent clouds (NLC) and polar stratospheric clouds (PSC). The potential role of NLC as tracer for mesospheric processes and variability, and as a tool for monitoring this remote and inaccessible region, has generated substantial interest within the scientific community.

    Sammanfattning : In this thesis, human behavior in rail tunnel fires is explored. Descriptive knowledge is presented related to the evacuation of passenger trains, and the subsequent tunnel evacuation to a safe location. LÄS MER

  5. 5. Diesel exhaust and wood smoke mechanisms, inflammation and intervention

    Detta är en avhandling från Umeå : Umeå Universitet

    Författare :Ala Muala; Umeå universitet.; [2014]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Air pollution; deposition; bronchoscopy; Immunohistochemstry; filter; NO bioavailability; lungmedicin; Lung Medicine;

    Sammanfattning : Background Particulate matter (PM) air pollution is associated with increased respiratory and cardiovascular morbidity and mortality. Diesel engine exhaust (DE) and wood combustion are major contributors to ambient air pollution and adverse health effects. LÄS MER
