different approaches have been presented for estimating river environmental flow which hydrological approach has a lot addressed because of its need to access to limited data and moderately rapid assessment. this approach incorporates various methods therefore comparison between results of different methods is essential. the objective of this study is to investigate and compare the consequences...

in the hot compression test friction has a detrimental influence on the flow stress through the process and therefore, correcting the deformation curve for real behavior is very important for both researchers and engineers. in this study, a series of compression tests were simulated using abaqus software. in this study, it has been employed the taguchi method to design experiments by the factor...

in the present study, the production of low-salt water from salty water by nanofiltration as well as membrane fouling was investigated. furthermore, a new method was proposed and tested experimentally for creating the backpulse in order to minimization of fouling and increase of the filtration efficiency. in the proposed method, the permeate was used instead of gas for creating the backpulse. t...
