[ 1 ] - حذف بخارات اتیل بنزن با استفاده از نانوکامپوزیت MnO2/Al2O3/Fe2O3پوشش شده بر روی بستر زئولیت HZSM-5
Background and aims: Ethylbenzene (EB) is one of the most hazardous carcinogenic VOCs that is used or produced in various industrial, so it is important to reduce its use and control its emissions. The aim of this study is determine the effectiveness of MnO2/Al2O3/Fe2O3 nanocomposite coated on HZSM-5 Zeolite for the removal of ethylbenzene vapors. Methods: Nanocomposite coated on HZSM-5 zeolit...
[ 2 ] - پالایش بخارات کلروفرم با استفاده از راکتور پلاسمای غیر حرارتی جدید (سال 1394)
Background and aims: One of the innovative technologies for air pollution control is non-thermal plasma. The dielectric barrier discharge reactor is one of the reactors that applied in non thermal plasma technology for air polluation control. In dielectric barrier discharge reactor, the distance between the electrodes for electric discharge is low and led to increasing space velocity of the pol...
[ 3 ] - مدل سازی مواجهه صدا در رانندگان اتوبوس های شرکت واحد تهران به روش شبکه عصبی
Abstract: Background: Many parameters effect on the noise exposure of bus drivers, which can be noted the bus type, where the engine, fuel type, age of buses and speed. The object of this study is the neural network modeling of noise exposure in Tehran bus transportation drivers. Material and Methods: Noise levels in 90 buses were sampled in three separate sub-sample including (1)30...
[ 4 ] - Survey of gender effect on driving performance and mental workload of Young Drivers using a driving simulator
Background and aims: Road traffic accident annually lead to the death of 1.2 million people and also the disability of some 50 million people in the world. Iran is one of the countries with the highest rates of road accidents in the world. According to the annual statistics by the Iranian Legal Medicine Organization, 15,932 people have lost their lives in road traffic accidents in 1395 sh. Acco...
[ 5 ] - Investigating the status of prevention of coronavirus in industries
Background and aims: Considering the high prevalence and lack of standard treatment for the new coronavirus, the best way in the current situation is to avoid infection and prevent its spread. In occupational environments, especially industries, due to air pollution with dust, gases and vapors and allergens and irritants, workers are susceptible to COVID-19 infection. Respiratory exposure of wo...
[ 6 ] - Development of a visual Basic 6.0 based smart application for the design and selection of local exhaust ventilation systems
Introduction: Air pollution in industrial work environments has adverse effects on worker health, for example, chronic obstructive pulmonary disease and asthma. These diseases impose direct and indirect costs on society. In hierarchy controls, local exhaust ventilation is considered an "engineering control" to remove or control contaminants released in indoor work environments. It is one of the...
[ 7 ] - Survey the effect of texting on driving performances using drivers driving a Simulator
Introduction: There is evidence that driver distraction is one of the major causes of vehicle accidents. One of the key factors that can affect people's driving performance drastically, is texting. Therefore, the purpose of this study is to determine the effects of texting on driving functions using a driving simulator. Methods and Materials: This study was conducted on 80 students ranging fro...
