Determination of Aerosol Particle Size Distribution using Electrical Differential Mobility Analyzer (DMA)
Introduction: Determining the size distribution of the particles for assessing their effects on human health and their control mechanisms is very effective. One of the most important equipment used in determining particle size distribution is the DMA. In this study, in addition to the design and construction of a DMA, the size distribution measurement of aerosol particles was carried out. Mate...
متن کاملStudying Peak Particle Velocity Due to Blast in Development Tunnels’ Face in Coal Stoping
The impact of blast-driven shocks on the safety and stability of the underground coal mines has been well established. The seismic imperfections resulting from blasting depend on the total explosive energy released during blasting and the closeness of the development tunnel face to the stope face. Also, the quality of the rock mass wherein the whole stope face is located might pose considerable...
متن کاملEfficacy of 3-Layer Felt Masks Containing Polypropylene Membranes in Particle Filtration with SARS-CoV-2 Size Range
Background and Aim: The use of a mask is an effective measure to reduce the transmission of Covid-19. Today, due to the lack of N95 masks and medical masks with good performance, felt masks are widely used due to their ease of manufacture and low cost. The aim of this study was to determine the effectiveness of 3-layer felt masks containing polypropylene membranes in filtering particle size in ...
متن کاملDesign and Construction of an Aerosol Particle Classification System Based on Electrical Mobility
Introduction: The application of particles’ electrical mobility in the electric field has always been an important concern, as the functional basis of a number of particle measuring and classification instrumentations. The objective of this study was to design and construct an aerosol particles classification system using electrical mobility feature in laboratory scale. Methodology: This labo...
متن کاملDesign of aerosol face masks for children using computerized 3D face analysis.
BACKGROUND Aerosol masks were originally developed for adults and downsized for children. Overall fit to minimize dead space and a tight seal are problematic, because children's faces undergo rapid and marked topographic and internal anthropometric changes in their first few months/years of life. Facial three-dimensional (3D) anthropometric data were used to design an optimized pediatric mask. ...
