Emission Control of Particles and Gaseous Pollutants with a High-Temperature Granular Bed Filter

Granular Temperature under Segregation in a Vibrated Granular Bed

The dominant mechanism affecting the flow behavior of granular materials is the random motions of particles resulted from the interactive collisions between particles. The velocity fluctuations induce the segregation in granular flows. The different physical properties of granular material were used to investigate the segregation in a vibrated granular bed in this paper. The image processing te...

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

Adsorption of Gaseous Pollutants

Is the Association of Airborne Particles with Daily Deaths Confounded by Gaseous Air Pollutants? An Approach to Control by Matching

Is the association of airborne particles with daily deaths confounded by gaseous air pollutants? An approach to control by matching.

Although particulate air pollution has been associated with increased numbers of daily deaths in dozens of cities around the world, issues still remain about the association. Some have questioned the complex modeling used to control for season in Poisson regression or the role of gaseous air pollutants as potential confounders of the association. I examined the association between deaths and pa...
