Although Iran's Ghaen Plain provides saffron to much of the world, no regional groundwater quality (GQ) assessment has yet been undertaken. Given the region's potential for saltwater intrusion and heavy metal contamination, it is important to assess the GQ and determine its main probable source of pollution (MPSP). Such knowledge would allow for informed mitigation or elimination of the potenti...

Saffron is an important crop in social and economical aspects in Khorassan Province (Northeast of Iran). In this research we tried to evaluate trends of saffron yield in recent years and to study the relationship between saffron yield and the climate change. A regression analysis was used to predict saffron yield based on 20 years of yield data in Birjand, Ghaen and Ferdows cities. Climatologic...

Cargo terminals are the gateways for entrance of commodities into the transportation network. Therefore, locating them in optimal location could have a major impact on the cost effectiveness and efficiency of transport, traffic safety and reduction in environmental pollutions. Due to the presence of a large number of parameters involved and the existing uncertainties, decision making in this fi...

events and accidents in drinking water distribution networks are among cases that lose water and increase the rate of non revenue water. network events in addition to wasting water can cause destruction, traffic jam, pressure reduction, pollution and enormous reconstruction costs.the main focus of this study is to statistically evaluate these incidents and to develop an analytical method to pre...

Saffron flowers harvested manually used as spice, dye or medicinal applications. The natural propagation rate most geophytes including saffron relatively low...

introductionclimate change has played an important role in all aspects of human life. therefore, climatepredictions in atmospheric general circulation models (gcm) will have particular importance.in this study, downscaling by a1b scenarios, ipcm4 and bcm2 of atmosphere generalcirculation models in lars-wg model are used for analysis of climate change impacts onmaximum and minimum temperature, s...

in order to study the effects of fall planting dates on yield and yield components of six cumin (cuminum cyminum l.) ecotypes an experiment was arranged in a randomized complete block design as a split-plot with three replications during 2007-08 growing season at the agricultural research station of ferdowsi university of mashhad. three planting dates (18 oct. (first), 8 nov. (second) and 29 de...
