the aim of the present study was to determine the in?uence of presence or absence of corpus luteum (cl) on hormonal and metabolites composition of follicular ?uid (ff) harvested from different sized follicles and its relationship with blood serum concentrations in sanjabi ewes. ovaries and blood samples were collected from 60 clinically healthy adult ewes (sanjabi breed) 1–3 years of age in dio...
Air pollution measurements during April 1991 are reported from the Craeybeckx highway tunnel in Antwerp, Belgium. The tunnel was used daily by an average of 45,000 vehicles, of which 60% were gasoline fueled passenger cars, 20% diesel cars, and 20% trucks. Of the gasoline cars, only 3% had three-way catalysts. Tunnel air concentrations of nitrogen oxides, sulphur dioxide, carbon dioxide, carbon...
This study investigated the seasonal variation of ambient air quality status of Burdwan town using GIS approach. Concentration of SO2 (sulphur dioxide), NO2 (nitrogen dioxide) and RSPM (respiratory suspended particulate matter) were measured once a week for 24 hour in both premonsoon and postmonsoon season. The seasonal average concentration of the RSPM, SO2 and NO2 in premonsoon season was obs...
Introduction: Emission of volatile organic compounds through industrial processes to the environment has been received more attentions currently. Photocatalytic oxidation process as a new emerging technique in air purification can be substituted for conventional techniques such as activated carbon adsorption. In photocatalytic oxidation process, pollutant molecules decompose to water and carbo...
Background and Objectives: There is a direct relationship between the air quality and human health. In this research, the air quality of Rafsanjan city was monitored regarding the concentration of some pollutants within a year. Materials and Methods: In this descriptive study, portable particle counter and air analyzer were used. Measurement of air pollutant parameters was done every two week...
conclusions according to the results of this study, this increase could be due to higher fuel consumption, usage of gasoline in vehicles, oil industry, and steel and heavy industries in ahwaz. the risk of mortality and morbidity were detected at the current concentrations of air pollutants. results according to the findings, the concentration of sulfur dioxide in ahvaz had an annual average of ...
Background:Consequences of air pollution on the health effects, including the formation and aggravation of respiratory ,neurological and cardiovascular disease, caused air quality monitoring and control as something inevitable in most urban & industrial areas issue that should be raised at national level. Industries are among important pollutant factors of the environment that contaminate thei...
The pattern of economic growth that we are adopting is increasingly associated with environmental pollution. It is clear that in the developing or developed countries increased mechanization, transportation, populations, etc. causes air pollution which is a major and effective environmental problem. Present study focuses on analysis of air pollution in Kannur city of Kerala. In this study, pred...
The present research analyzes air quality in Ahvaz, a city in the south of Iran, paying special attention to sulfur dioxide (SO2). In order to prepare the average data in the city, measurements have been carried out between 2009 and 2010 in two different locations. Relations between sulfur dioxide and some meteorological parameters have been calculated statistically, using the daily average dat...
