The movement of smoke; the diffusion and flow of coloured water, mercury, oil, and so on; pneumatic inflation and deflation; and the movement of masses of bubbles have all served as media for kinetic sculpture.
Since the height of the neutral plane is related to the direction of the high-temperature smoke and airflow diffusion of fires in high-rise buildings, the identification of the neutral plane is important for both the evacuation of residents and the safety of fire fighters.
PM2.5 concentration was measured using Harvard impactors (Air Diagnostics and Engineering Inc., Naples, ME, USA); PM2.5 absorbance was assessed from the reflectance of the particulate filters by M43D Smoke Stain Reflectometer (Diffusion Systems Ltd., Hanwell, UK) (Hoek et al. 2002), and NO2 concentrations by Palmes tubes (Cyrys et al. 2000).
We propose the difference in trumpet circumference may have an impact on smoke velocities and therefore diffusion and deposition within the chamber.
Threshold sooting index (TSI), which correlates linearly with the ratio of fuel molecular weight and smoke point in a diffusion flame, is proposed as a new lumped parameter for sooting tendency correlation.
Yet, the low smoking prevalence, lack of association between education and cigarette smoking and high probability of never having smoked does not indicate that any diffusion of smoking habits has taken place.
The collected filters were then measured using Smoke Stain Reflectometer (model 43; Diffusion Systems Ltd).
Filters were analyzed gravimetrically and for light reflectance using a Smoke Stain reflectometer (M43D EEL; Diffusion Systems Ltd., London, UK).
The researchers monitored smoke exposure via a passive diffusion CO tube attached to the mothers' and children's clothing.
We determined soot content of the filters using a smoke stain reflectometer (model M43D, Diffusion Systems Ltd., London, UK).
