climate change is one of the most important factors that will affect different parts of human life on earth and will be adverse effects on environmental resources, economic, social and especially water resources, with changes in rainfall and timing of runoff amount.one of the strategies to mitigate the effects of climate change is to assess its effects on precipitation, temperature and runoff i...

Meteorological satellite data and images have been operationally utilized in weather services for more than 30 years. Since the inception of weather forecasting based on satellite remote sensed data, meteorologists have faced the challenge of using this tool to minimize the potential damage caused during adverse weather conditions by collecting and analyzing these images. Based on this analysis...

the purpose of this study is the analysis of the farmers economic behavior to reduce the adverse environmental effects of agricultural chemical inputs by using contingent valuation approach and tobit model by heckman's two stage. to achieve the desired goal, 100 questionnaires collected by a random sampling from farmers of kashaf- rood basin in mashhad city in 2013. results showed that variable...

Many Alpine rivers are affected by hydro-peaking, strong sub-daily fluctuations of discharge caused by intermittent power production from hydropower plants. Adding a retention volume at the outlet of a hydropower plant aims at attenuating hydro-peaking to a level where adverse effects on fish and invertebrates are minimal. The performance of such a retention volume needs to be assessed when ext...

Although nitrate is recognized as the most common groundwater contaminant due to growing anthropogenic sources, such as agriculture in particular, its adverse effects on human and animal health are debatable. The current issue, however, is to control and reduce nitrate contamination with regards to the long residence time of groundwater within aquifers. Denitrification has recently been recogni...

the purpose of this study is to evaluate financial participation of farmers to reduce the adverse environmental effects of contaminated water by using contingent valuation approach and tobit model by heckman's two stage. to achieve the desired goal, 100 questionnaires collected by a random sampling from farmers of kashaf- rood basin in mashhad city in 2014. results showed that variables of age,...

background : following establishment of iranian adverse drug reaction (adr) monitoring  center  in  1997, adr  committees  were  established  in  all  hospitals  of mazandaran province of iran. clinical pharmacists from mazandaran university of medical sciences have been involved with these committees since 2007. the aim of this study was to compare the results of the pharmacovigilance system b...

Recent tropical seasons in the Atlantic basin have been quite active. This has translated to an increased frequency of land falling tropical cyclones in the United States. In several instances, a concentrated area of heavy rainfall was observed well upstream from the land falling tropical system itself; separate from the cyclone’s primary precipitation shield. In some of the more pronounced cas...

In dynamical systems examples are common in which two or more attractors coexist and in such cases the basin boundary is non-empty. The purpose of this paper is to describe the structure and properties of basins and their boundaries for two-dimensional diffeomorphisms. If a two-dimensional basin has a basin cell (a trapping region whose boundary consists of pieces of the stable and unstable man...
