The assimilation potential (assimilative capacity) of the atmosphere can be represented in two ways: one as the ventilation coefficient and the other as the dispersion potential of emission loads discharged into the region. In the present study, the atmospheric assimilation potential of a typical urban area in Kochi city has been determined with respect to sulfur dioxide (SO(2)). The ventilatio...

Background & objective: Industrial ventilation systems and dust collectors are effective solutions to reduce particulate emissions in the workplace and environmental in mineral processes. In this study, Local Exhaust Ventilation System and dust collectors for control of emitted silica, coke, silicon carbide dusts from crushing unit was designed and evaluated.

Introduction: Adherence to the design values and ventilation standards (VS) after installing and also maintaining continuous work of ventilation system with maximum performance throughout its life are amongst the reasons of ventilation systems monitoring. Therefore, the aim of this study was to evaluate performance of local exhaust ventilation system for control of dust by measuring the operati...

Background & Objectives : Hospital indoor air contains a wide range of airborne pathogenic bioaerosols which have a significant impact on health care staff’ health and welfare. The aim of this study was to assess the effects of ventilation system types on occupational exposure of the health care staffs to airborne bioaerosols in the isolation room based on the patient bed arrangements and...

I applied well-known hierarchical clustering algorithms to datasets of workstation activity during fiveminute intervals recorded over periods of time ranging from 9 days to one month. I grouped together workstations into ventilation subsystems based on the usage data as well as static pressure values measured in the factories. In simulations, I achieved significant energy savings even when the ...
