  2. 1. Cabin Air Quality in Commercial Aircraft : Exposure, Symptoms and Signs

    Author : Torsten Lindgren; Dan Norbäck; Gunilla Wieslander; Jan Sundell; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; airline crew; aviation medicine; micro-organism; cabin air quality; air humidity; atopy; occupational exposure; environmental tobacco smoke ETS ; psychosocial work environment; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; arbets- och miljömedicin; Occupational and Environmental Medicine;

    Abstract : The objective of the dissertation was to study the cabin environment, and identify personal and environmental risk factors, associated with symptoms, and perception of cabin air quality. Another objective was to study if ban of smoking, and increased relative air humidity on intercontinental flights, could have a beneficial health effect. READ MORE

  4. 2. On the fracture behaviour of softwood : a combined experimental and computational study of the interaction between fracture behaviour and material anatomy

    Author : Lars Olof Jernkvist; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : The propensity for fracture, i.e. failure through separation of the material, is a factor that must be regarded in the design of wooden structures, but also in wood machining operations and drying. READ MORE

  5. 3. Towards International Chemical Safety : Taking Action on Persistent Organic Pollutants

    Author : Henrik Selin; Loftsson Elfar; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Convention on Long-Range Transboundary Air Pollution CLRTAP ; persistent organic pollutants POPs ; regime analysis; social learning; Miljö; Föroreningar; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : Persistent organic pollutants (POPs) have been subject to increased international ro-operation over that past decade. The first international effort to address POPs collectively as a distinet class of pollutants was made under the United Nations Economic Commission for Europe (UNECE) and within the framework of the Convention on Long-Range Transboundary Air Pollution (CLRTAP), which geographically covers North America, Europe and the region of the former Soviet Union.

    Abstract : Industrial living is caused much people do live and work in closed and confined places; offices and residential buildings. This is why in this new world more fresh air which is generally provided by forced ventilation plays a vital role in living of human being. READ MORE

  7. 5. Aerothermal Study of Intermediate Turbine Ducts

    Author : Martin Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerodynamics; Intermediate Turbine Duct; Gas Turbine; Heat Transfer; Experimental;

    Abstract : An intermediate turbine duct guides the flow from the smaller diameter high pressure turbine to the downstream larger diameter intermediate or low pressure turbine. It is typically equipped with a structural vane transferring loads for the core to the external parts, and supplies the core with necessary services such as oil and air. READ MORE
