Focusing on environmental impact assessment as a new tool to determine the harmful effects of projects on the environment is very necessary. The establishment of cement plants in Iran is accompanied by huge investments that aim to create jobs and have others economic aspects; this trend is on the rise. However, cement plants contribute to environmental pollutions. Therefore, understanding the e...
Rapeseed as one the most crops is the basic needs of human feeding in order to produce oil. A field experiment was conducted to study the effects of different tillage system, seeding method and rates on yield and its components, as well as, seed oil percentage of rapeseed (Brassica napus L. cv. Hyola-401) during 2011-12 growing season at Rice Research Institute of Iran-Department of Ma...
one of the most important factors in study of project’s , is the study of environmental opportunities factors the permanent study of environmental opportunity factors . the study of permanent environmental changing and knowing golden threats’ cooperate with possible threats and at the result in structure forming and future skeleton of organization has a vital effects . the petrochemical industr...
BACKGROUND Weather is a potentially important determinant of physical activity. Little work has been done examining the relationship between weather and physical activity, and potential modifiers of any relationship in older people. We therefore examined the relationship between weather and physical activity in a cohort of older community-dwelling people. METHODS We analysed prospectively col...
A simplified environmental biological model has been developed based on biodegradation kinetics correlation to regulate and optimize wastewater treatment system of activated sludge process. All parameters included in the model are calibrated in accordance with reference data and experimental results and good agreements are achieved between calculated results and reference data or experimental r...
