Background & Aims of the Study: Ozone is a summer pollutant which can cause respiratory complications, eye burning sensation and failure of immune defense against infectious diseases. Ahvaz city (southwestern Iran) is one of the seven polluted Iranian metropolises. In this study we examined the health impacts of ozone pollution in Ahvaz city during years 2010 and 2011. Ma...
abstract the primary purpose of this study was to explore the actual practices and cognitions of two groups of iranian eap teachers, i.e. language teachers and content teachers, with respect to teaching reading-comprehension and vocabulary. to this end, tehran university of medical sciences which authorizes both groups of teachers to teach eap courses was selected as the context of the study s...
Background and Objective: Skin ulcers and their slow healing are considered as one of the important medical aspects. Nowadays, various antibiotics and materials are used to accelerate the wound healing process. One of the methods taken in the field of wound healing is using ozone. On the other hand, one of the factors that hurt the speed of wound healing is stress. Therefore, the present study ...
air pollution is a challenging issue in some of the large cities in developing countries. air quality monitoring and interpretation of data are two important factors for air quality management in urban areas. several methods exist to analyze air quality. among them, we applied the dynamic neural network (tdnn) and radial basis function (rbf) methods to predict the concentrations of ground-level...
The dangers posed by O3to historical properties and art works, as well as limited accessibility and inapplicable instrumental methods for measuring O3concentrationhave made it much more necessary to use low tech and inexpensive methods for this purpose in almost all museum environments. On the other hand, elastomers are known as polymers with high reactivity to ozone and latex as a natural elas...
[1] The statistical relationship between springtime and summertime ozone over middle and polar latitudes is analyzed using zonally averaged total ozone data. Shortterm variations in springtime midlatitude ozone demonstrate only a modest correlation with springtime polar ozone variations. However by early summer, ozone variations throughout the extratropics are highly correlated. Analysis of cor...
