[ 1 ] - A Study of Features of Backpack Carrying Methods by Schoolchildren: A Population-Based Study
Background: Nowadays, backpack is the best and most commonly used tool for carrying books and stationery by students. There are huge evidences which confirmed that carrying method of school backpack influences on the students’ health status. The aim of this study was to determine of features of backpack carrying methods by schoolchildren.Materials and Methods: A cross-sectional study was conduc...
[ 2 ] - Evaluation of X-Ray Radiation Levels in Radiology Departments of Two Educational Hospitals in Ahvaz, Iran
Introduction: The ionizing radiation is increasingly applied in various fields for industrial and medical purposes due to its benefits. The aim of this study was to measure the radiation levels in six radiology departments of two educational hospitals in Ahvaz, Iran. Materials and Methods: The radiation levels were measured at six locations of six radiology departments, including behind the pat...
[ 3 ] - استفاده از وسایل حفاظت شنوایی با رویکرد درک ریسک کاهش شنوایی ناشی از سروصدا در تعدادی ازصنایع تولیدی
Background & Objective : Noise is a widespread physical agent and although is a most risk factors in workplaces that workers of health to exposed. Thus, different actions is done for reduce exposure to it in work places, which one of them is use of hearing protection devices. The use of hearing protection devices with approach risk perception of noise induced hearing loss in several manu...
[ 4 ] - Removal of styrene from air by photocatalytic process of Zeolite Socony Mobil-5 coated with zinc oxide nanoparticles
Background: Volatile organic compounds (VOC) are considered as major environmental contaminants that have a harmful effect on human and ecosystem health, so much effort has been focused on their removal. The aim of this study was to investigate the removal efficiency of styrene by Zeolite Socony Mobil-5 (ZSM-5) after immobilization of nanoparticles of zinc oxide (ZnO) on it. Materials and Meth...
[ 5 ] - Effect of Nano-TiO2 Immobilized on Activated Carbon, Zeolite Y and ZSM-5 on the Removal of Styrene Vapors from Polluted Air
TiO2 is a very well-known and well-researched material due to the stability of its chemical structure, biocompatibility, and its physical, optical and electrical properties. In this study, the synergistic effect of nano-TiO2 immobilized on activated carbon, zeolite Y and ZSM-5 on the removal of styrene vapors from polluted air was investigated. The prepared catalysts were characterized by SEM, ...
[ 6 ] - تعیین استرس ناشی از صدا با سنجش تغییرات کورتیزول بزاقی
Introduction: Noise exposure is known as a risk factor for hearing loss and one of its effects is noise-induced stress. Cortisol, as stress hormone- is used in noise-induced stress assessments studies. The aims of this study were:(1) measuring and comparing saliva cortisol concentrations in the morning and evening in normal work day and rest day between two groups, (2) assessing the relationshi...
[ 7 ] - survey effect of illuminance source on alertness in a laboratory design
Background and aims: Workplaces with poor lighting conditions often created occupational accidents or illness. This occurs because light cause visual and nonvisual effects on numerous physiological variables, such as the human sleep-wake cycle and cognitive performance. Indoor lighting conditions, as one aspect of the work environment, Influence on occupant’s mood, well-being, task performance ...
[ 8 ] - Measurement of exposure to radionuclides (40-K, 226-Ra, and 232-Th) in the oil and gas drilling industry
Background: Naturally occurring radioactivity is a root cause of human exposure to harmful radiation. The occupational exposure hazard due to natural radionuclides occurring in drilling wastes is especially important in this regard. In this study the concentration of radionuclides namely 232Th, 226Ra and 40K were assessed in soil samples that were taken from various oil drilling areas. Methodol...
[ 9 ] - Photocatalytic removal of ethylbenzene from air flow using ZnO nanoparticles immobilized on modified natural zeolite
Introduction: Ethylbenzene is a volatile organic compound used in many industries, including oil and gas, oil colored and insecticides. Due to the toxic effects of this chemical substance, control and elimination of this vapor is necessary. Photocatalytic degradation is a possible method to remove organic compounds from air. This study was performed to determine the efficiency of photocatalytic...
