introduction: previous studies indicate that exercise influences cognitive function. nevertheless, considering that exercise in animal study can be voluntary, or forced, effects of exercise (specially forced exercise) on learning and memory abides as a matter of controversy. the present study aimed to investigate the effects of treadmill exercise on ltp in the dentate gyrus of rats. methods: th...

introduction: over the last decade, exposure to non-ionizing electromagnetic waves due to base station antenna has increased. this in vivo study was planned for evaluating the effects of whole-body exposure to 950 mhz field of gsm mobile phone system on rat dentate gyrus long-term potentiation. materials and methods: 24 naive male wistar rats (3 month old, 225|¡|25 g) were randomly divided in t...

sewage effluent is the carrier of huge amounts of n (0.09 to 0.16%), p (0.023 to 0.029 %), and k (0.11 to 0.18%) and as well as it is rich in organic carbon (3.27%). transfer of the toxic trace metal (pb) from the contaminated site can be seized out from the food chain through application of feso4.7h2o and caso4 in a larger area. the efficacy of the toxic metal immobilization through an applica...

Runoff information can be used for establishing watershed water management plans. However, hydrological models with complex parameters make it difficult to quickly estimate runoff. This study developed a one-parameter new exponential (ONE) model simulating rainfall-runoff using single parameter, which was designed based on nonlinear function and balance that varies according the soil storage. T...

The drought event which reached severe levels in 1972 and 1973 caused a major disaster in the Sahalian and sub-Sahalian zones in Africa. This disaster has drawn attention to the need for data surveys and detailed studies for meaningful long-term measures to combat the effects of future droughts. The study reported in this paper is an attempt to assess the hydrological aspects of the drought eve...

Abstract The accuracy of medium- and long-term runoff forecasting plays a significant role in several applications involving the management hydrological resources, such as power generation, water supply flood mitigation. Numerous studies that adopted combined models to enhance have been proposed. Nevertheless, some do not take into account effects different lag periods on selection input factors....

In the application of medium and long-term runoff forecasting, machine learning has some problems, such as high cost, limited computing difficulty in satisfying statistical data assumptions regions, leading to popularization hydrology industry. case a few data, it is one ways solve problem analyze characteristics consistency. This paper analyzes hypothesis periodicity mutation. Aiming at effect...
