11. By 1985, a three-dimensional configuration was introduced specifically to measure the scattering properties of single aerosol particles . 12. Tuck has already worked out that aerosol particles on Mars would be smaller than those on Earth. 13. An impinger system is a device in which particles are removed by impacting the aerosol particles into a liquid. 14. Lidar can also be used to measure wind speed and to provide information about vertical distribution of the aerosol particles . 15. When a depleted uranium round strikes armor or burns, it produces uranium dusts or aerosol particles , which can be inhaled. 16. The former framework is used for measuring aerosol particles while the latter was used to examine marine organisms such as phytoplankton. 17. The location of deposition of aerosol particles within the respiratory system strongly determines the health effects of exposure to such aerosols. 18. He also, with V . H . Guerrini, developed in 1935 the diffusion battery for measuring the size of aerosol particles . 19. These may be gas phase, such as molecular iodine or noble gases, or condensed aerosol particles after leaving the high temperature region. 20. Computer models can be used to understand the behaviour of aerosol particles , and are particularly useful in modelling their effect on global climate.
