  1. 1. Experimental measurements of water mist systems and implications for modelling in CFD

    Detta är en avhandling från Department of Fire Safety Engineering and Systems Safety, Lund University

    Författare :Bjarne Husted; Lunds universitet.; Lund University.; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Technological sciences; fire suppression; CFD; FDS; fire safety engineering; PDA; water mist; PIV;

    Sammanfattning : The use of water mist for fire extinguishment has increased rapidly in recent years. The main reason is the abandonment of halon-based extinguishing systems in favour of environmentally friendlier systems. Furthermore the use of water mist systems has spread from mainly marine applications to also include the protection of buildings. LÄS MER

    Sammanfattning : Popular Abstract in Swedish Ett beräkningsprogram, "FREIA", lämpligt för industriell brandriskanalys presenteras. Programmet beräknar skada på människor inom och utom en byggnad på grund av en brand eller ett utsläpp av farligt gods. För några av de i riskanalysen ingående momenten har ytterligare forskning utförts. LÄS MER

  3. 3. Studies on Airway Surface Liquid in Connection with Cystic Fibrosis

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Inna Kozlova; Uppsala universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cystic fibrosis; CFTR; airway surface liquid; ion content; anesthesia; mist tent therapy; Pseudomonas aeruginosa infection; NATURAL SCIENCES Biology Cell and molecular biology Cell biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Cellbiologi;

    Sammanfattning : Cystic fibrosis (CF) is one of the most common fatal inherited diseases, most prevalent among Caucasians. CF is caused by a mutation in the gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR), which helps to create sweat, digestive juices, and airway surface liquid (ASL).

    Sammanfattning : Lithium-ion batteries offer high energy and power densities as well as long life time but have a more narrow stability window compared to other battery types and contain reactive and flammable materials. In case of overheating the battery cell can release gas (vent) and, at temperatures of about 150-200 °C, a so called thermal runaway can occur, that is a rapid self-heated temperature increase which is typically accompanied with a large release of smoke and gas, fire and a potential cell case explosion or gas explosion.
