Extensive arsenic contamination of groundwater, rivers, and agricultural farms has led to widespread poisoning consequent problems associated with health economy. In recent years, many studies have been performed understand bacterial detoxification metabolism which paved the way for bioremediation applications. This study attempted isolate characterize arsenic-resistant bacteria from drying Urm...

Urmia Lake, which is the second largest permanent hypersaline lake in world, shrinking recent decades. Since accurate spatial information about essential to managing current and emerging crises of lake, this study used Lake satellite images time-series investigate drought trends by analyzing via Artificial Neural Networks (ANN). The proposed approach comprising following four steps. First, year...

most of the environmental threates and resources depletion are direct consequences of human behavior, so altering the behavior could decrease environmental problems. in this regard, identification of the effective factors on behavior would be the first step. lake urmia as a public good, needs public contribution to prevent its more deterioration that could have serious impacts on social welfare...

Specifying the soil types and profiling the subsurface soil layers are the excellent examples of CPTu test potentials. In this research, the capability of CPTu test for specifying subsurface soil layers and classification of sediments in Urmia Lake is investigated. According to previous studies, the sediments of Urmia Lake are commonly fine grained and soft deposits with organic materials. To e...

Precise forecasting of streamflow is crucial for the proper supervision water resources. The purpose present investigation to predict successive-station using Gated Recurrent Unit (GRU) model and quantify impact input information (i.e., precipitation) uncertainty on GRU model’s prediction Generalized Likelihood Uncertainty Estimation (GLUE) computation. Zarrineh River basin in Lake Urmia, Iran,...

Urmia Lake (also known as Oroumieh Lake) is a shallow terminal lake located in northwest Iran and one of the largest permanent lakes in the Middle East. Due to its biodiversity it has been designated as a Biosphere Reserve by UNESCO and a National Park under the 1971 Ramsar Convention. At present, the entire lake’s watershed is threatened due to drought and abrupt decline of the lake’s water le...

PURPOSE Carotenoids are of great interest in many scientific disciplines because of their wide distribution, diverse functions and interesting properties. The present report describes a new natural source for carotenoid production. METHODS Halorubrum sp., TBZ126, an extremely halophilic archaeon, was isolated from Urmia Lack following culture of water sample on marine agar medium and incubati...
