  4. 3. Cabin Air Quality in Commercial Aircraft : Exposure, Symptoms and Signs

    Författare :Torsten Lindgren; Dan Norbäck; Gunilla Wieslander; Jan Sundell; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 4. Deliberations on the impact of antibiotic contamination on dissemination of antibiotic resistance genes in aquatic environments

    Författare :Björn Berglund; Per-Eric Lindgren; Dan I. Andersson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The great success of antibiotics in treating bacterial infectious diseases has been hampered by the increasing prevalence of antibiotic resistant bacteria. Not only does antibiotic resistance threaten to increase the difficulty in treating bacterial infectious diseases, but it could also make medical procedures such as routine surgery and organ transplantations very dangerous to perform.

  7. 5. Dislocation density based material model applied in FE-simulation of metal cutting

    Författare :Dan Wedberg; Bevis Hutchinson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik;

    Sammanfattning : Simulation based design enables rapid development of products with increased customer value in terms of accessibility, quality, productivity and profitability. However simulation of metal cutting is complex both in terms of numeric and physics. The work piece material undergoes severe deformations. LÄS MER
