   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

3. 7. Head Injuries in Car-to-Pedestrian Accidents - Investigation of Head Impact Dynamics, Injury Mechanisms and Countermeasures

   Författare :Jianfeng Yao; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; accident analysis; head injury; head protection; mathematical simulation; accident reconstruction; injury mechanism; Pedestrian accident;

   Sammanfattning : The aim of this study was to investigate head impact dynamics and to establish risk functions for head injuries by mathematical reconstructions of real-world car-to-pedestrian accidents. Furthermore, an attempt was made to develop an approach for the design and evaluation of head-protective devices. LÄS MER
