Particulate matter (PM) models are used for demonstration of progress in visibility under the Regional Haze Rule and the formulation of State Implementation Plans (SIPs) for the PM2.5 National Ambient Air Quality Standards (NAAQS). For models to be used convincingly in the regulatory arena, they must first be shown to produce satisfactory performance . The evaluation of models is a data-intensi...

background: in the past few decades, indoor air pollution (iap) has become a primary concern to the point. it is increasingly believed to be of equal or greater importance to human health compared to ambient air. however, due to the lack of comprehensive indices for the integrated assessment of indoor air quality (iaq), we aimed to develop a novel, fuzzy-based indoor air quality index (fiaqi) t...

Introduction: Air pollution is now one of the greatest environmental hazards to human health in the world. The aim of this study determines the relationship between air quality and cases of myocardial infarction in Yazd. Methods: This Ecological study was performed in Yazd, Iran. In this study, all individuals who referred to emergency cases with myocardial infarction in Yazd in one year from ...

background:: this study developed a smart co 2 detector, which attach to the general ventilation system to reduce the gas level. methods: indoor air quality measurement was performed in five selected rooms between january 2015 to february 2015 using tsi q-trak tm indoor air monitor 7575. the perceived indoor air quality conditions was gathered using questionnaires adopted from the industrial co...

background: contemporary development of growing urban communities and increasing the economical and industrial activities in the current century without paying attention to assess the effect of these activities on human health, as the axis of the development, is caused urban air pollution and risks from different pollutant emissions. tehran air pollution has received considerable media coverage...

conclusions in order to diminish the health impacts of particulate matter in khorramabad, health training for the public, especially for persons with chronic lung and heart diseases, the elderly, and children, should be conducted by health systems to encourage them to reduce their activities during dusty days. materials and methods the pm10 sampling was carried out with a high-volume sampler at...

The Squale project was born from industrial effort to control software quality. Its goals are to refine and enhance Qualixo Model, a software-metric based quality model already used by large companies in France (Air France-KLM, PSA Peugeot-Citroën) and to support the estimation of return on investment produced by software quality. Qualixo Model is a software quality model based on the aggregati...

background: air pollution and concerns about health impacts have been raised in metropolitan cities like tehran. trend and prediction of air pollutants can show the effectiveness of strategies for the management and control of air pollution. artificial neural network (ann) technique is widely used as a reliable method for modeling of air pollutants in urban areas. therefore, the aim of current ...
