Nanofibre filters may offer new properties not available in commercial fibre filters. These include a higher surface area and the ability to novel materials within fibres. In addition small size allows potential gains performance due slip-flow phenomenon which normal gas viscosity does apply objects smaller than mean free path of gas. We tested electrospun generated from polyvinyl alcohol solut...

population growth, industrial pollution and high-energy consumption, cause the release of significant amounts of pollutants in the environment. power plants play an important role in the release of pollutants such as sulfur dioxide, nitrogen oxides, and carbon dioxide. if the necessary measures in the field of prevention and control do not be implemented, human health and other living creatures...

The study aimed to appraise the effect of different air pollutants viz. SO2, NOx, SPM and RSPM on biophysiological as well as yield characteristics of wheat and mustard plants grown at different sites in the urban and industrial areas of Haridwar City. The ambient levels of air pollutants were lowest at site 2 and 4 and hence these sites were treated as control sites for comparing the response ...

Non-thermal plasma reactors have recently been used for the treatment of gaseous pollutants. High energy electrons (several eV) are produced in the plasma while the gas remains near ambient temperatures. Pollutant molecules are decomposed by highly reactive chemical radicals created through electron collisions. The focus of this work is the treatment of pollutants from the exhaust of electric a...

The association between total daily mortality and air pollution was investigated for a 1-year period (January 1995 to December 1995) in Inchon, Korea. The purpose of this study was to evaluate the relative importance of particulate and gaseous air pollution as predictors of daily mortality. Concentration of total suspended particulates (TSP), inhalable particles (PM10), and gaseous pollutants, ...

The distribution of airflow in a residential building varies with the periodic operation of a heating, ventilating and airconditioning (HVAC) system. Depending on the HVAC fan operation, mixing airflow (fan ON) or stratified airflow (fan OFF) occurs in the space. The objectives of this study are 1) to examine the time needed for room air to stabilize after a central ventilation fan turns ON/OFF...

A lifecycle environmental impact analysis was conducted for SF6 used as an insulating gas in electrical devices. Eight scenarios with different forms of usage as an insulating gas (pure SF6 and gaseous mixture of SF6 with nitrogen) and treatment processes of waste SF6 (e.g., reproduction after decomposition, reuse after purification) are assumed. Energy consumption and emission of pollutants an...
