introduction after the rapid population growth in the iranian cities, these cities have experienced great changes. the physical structures of the cities are eroded and the managers have no attention to them. many immigrants entered the cities  have dwelled in the inefficient urban textures like in the marginal areas and old textures. thus, the environmental quality of place has been weak. undes...

The reduction of agricultural nonpoint source (NPS) pollution is essential to protect the quality of North Carolina's water resources. In order to reduce these pollutants, increased implementation of Best Management Practices (BMPs) by individual producers is being proposed. Recommended BMPs include soil and water conservation practices, fertilizer and animal waste management and integrated pes...

Normalisation of environmental data aims at clarifying the human impact on the environment by suppressing meteorologically driven fluctuations and other natural variation in the collected data. This paper shows that the procedures presently used to adjust air and water quality data have a common probabilistic framework. Furthermore, this framework can support a number of new techniques for the ...

OBJECTIVES An increasing number of reports suggest that chemical and physical agents in the environment, introduced and spread by human activity, may affect male fertility in humans. This article aims at evaluating the impact of environmental exposures (pesticides, phthalates, PCBs, air pollution, trihalomethanes (THMs), mobile phones) on semen quality, by reviewing most recent published litera...
