Theoretical Optimization of Troposphere Ionization Exchange Points to Reduce the Concentration of Fine Dust in Ahvaz City, Iran
Aims: The dust crisis and the numerous problems caused by it, which have affected most of the Western and Southwestern regions of Iran in recent years, need an appropriate and cost-effective solution to improve living and respiratory conditions without adverse human or environmental effects. The purpose of this study was to analyze the location of injection technology equipment to reduce the co...
متن کاملExperimental Investigation of Friction Coefficient in Ribleted Pipes and the Effect of Fine Particles
The effect of fine particles on turbulence damping and reduction of flow friction coefficient in ribleted pipes, have been investigated experimentally. Tests have been conducted in a ribleted pipe with hydraulic diameter of 18.6 mm, and 20 stream wise riblets of 1.8 mm depth, along the pipe. Flows of water tap with Reynolds number from 5000 to 30000 were compared with flows containing silt-clay...

This discussion paper is/has been under review for the journal Atmospheric Chemistry and Physics (ACP). Please refer to the corresponding final paper in ACP if available. Abstract A detailed characterization of air quality in Paris (France), a megacity of more than 10 million inhabitants, during two one month intensive campaigns and from additional one year observations, revealed that about 70 ...
متن کاملFine Particles Processing
It is vell known that fines and ultrafines can cause severe problems in mining and mineral processina. The decrease in the grade of ore combined with the arowinS demand for aineral products baa led to the minina and milling of increasing tOQnage or ore. Cl08ely linked with the problem of reduction in the grade of ore is. the more serious problem of the decrease in libration size. A direct cODsq...
متن کاملFine particles and mortality.
In an interesting paper in a recent issue (vol 17, issue 14) of the journal, Enstrom examined the association between fine particulate matter (PM) pollution and mortality in a cohort of elderly Californians. The analyses used proportional hazards regression and after adjusting for age, sex, cigarette smoking, and other potential confounders, Enstrom concluded, “These epidemiologic results do no...
