inhalation delivery of aerosolized antibacterials is preferred over conventional methods of delivery for targeting lung infection. the present study is concerned with the development and characterization of a novel, spray dried, aerosolized, chitosan polyelectrolyte complex (pec) based microparticles containing antibacterials for the treatment of lung infections.chitosan polyelectrolyte complex...

background: welding is one of the most exercised industrial processes which welders are exposed to chemical and physical hazardous agents. this study was conducted to evaluate occupational and environmental exposures to aerosols generated by welding processes in a factory. methods: a total of 28 samples of aerosols were collected at 4 different locations including indoor, outdoor, source of wel...

background: most rural carpet weaving workshops are part of the house and sanitary conditions of the workshop not only affect the weaving but also other family members this study aimed to determine the aerosol and bioaerosols concentration in the rural household carpet weaving workshops in isfahan. methods: in this this study is a cross - sectional study and was performed in 92 rural household ...

The effect of the surface roughness of solid atmospheric aerosol particles on their heterogeneous nucleation capability has been examined using the concept of Aself-affineB rough surfaces. The surface roughness has a great influence on the contact angle between the particle surface and the nucleating liquid droplets. Roughness enhances wetting and the rate of heterogeneous nucleation from the v...

In a reverse microemulsion consisting of water, oil (octane), an anionic surfactant [aerosol OT (AOT)], and the reactants of the oscillating Belousov-Zhabotinsky (BZ) reaction, a variety of complex spatiotemporal patterns appear. These include traveling and standing waves, spirals that move either toward or away from their centers, spatiotemporal chaos, Turing patterns, segmented waves, and loc...

indicate a near-100% deposition efficiency of the aerosol entering the precipitator. The final objective is to have a precipitator, for which the particle deposition rate can be calculated as a function of particle size and operating conditions.
