    Sammanfattning : Fine airborne particles are associated with adverse health effects in the human population. The aim of this research was to develop and evaluate methods for in-situ characterisation of fine and ultrafine particles and to determine their deposition in the human airways. LÄS MER

  5. 9. Dynamic Mechanical Studies of Wood, Paper and some Polymers Subjected to Humidity Changes

    Författare :Reza Ebrahimzadeh Pirshahid; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood; paper; mechanosorption; hygroscopic polymers; PEO; cellophane; PVAc; PA6; diffusion; dynamic mechanical properties;

    Sammanfattning : The dynamic mechanical response of several hygroscopic materials including wood (Scots pineveneer), paper (unbleached sulphate), cellophane, polyamide 6 (PA6) and poly(vinyl acetate)(PVAc) have been studied especially under conditions of a stepwise varying humidity in the atmosphere surrounding the samples. In all cases the in phase and out of phase components of the force necessary to achieve a given deformation were measured for various oscillation frequencies (from 0. LÄS MER

  7. 10. Multiphase continuum modeling of wood : A hybrid mixture theory approach
