background wastewaters with high salt content disturb the metabolic function of microorganisms causing plasmolysis or activity loss in microorganisms, so the efficiency of biological treatment of saline wastewater by conventional microorganisms will decrease. objectives this study aimed to find the outbreak of disorder in the biological wastewater treatment process and how much salt leads to lo...
abstract the present study deals with a comparison between reactive and pre-emptive focus-on-form in terms of application and efficiency. it was conducted in an intermediate english class in shahroud. 15 male learners participated in this research and their age ranged from 18 to 25. a course book, new interchange 3, and a complementary book were used. every session the learners gave lectures o...
Effect of deficit irrigation on evapotranspiration, yield, water use efficiency and some growth parameters of Hamadanian pepper (Bivar) using a completely randomized design (CRD) with a full irrigation treatment (FI) and three deficit irrigation treatments (85, 70 and 55% application of water requirement; DI85, DI70, and DI55, respectively) in five replications was examined. Evapotranspiration ...
an efficiency-centred hierarchical model is developed to assess the performance ofwastewater treatment plants (wwtps). specifically, a new treatment performance index (tpi) hasbeen proposed to determine the overall treatment performance of wwtp by analysing the tpivalues and the weights of individual treatment phase for overall treatment performance. threemodules have been developed to examine ...
In order to investigate the effect of combination of chemical and biological fertilizers on dry matter, uptake and efficiency of nitrogen (N), phosphorus (P) and zinc (Zn) by fenugreek (Trigonella foenum- graecum), an experiment was conducted as randomized complete blocks design with three replications in the Research Greenhouse of Shahrekord University. Eight fertilizer treatments consisted of...
introduction: due to the risks of hormones on human health and aquatic life, the aims of this study were to determine the efficiency of estrogen removal in the different stages of shiraz wastewater treatment plant using activated sludge process and marvdasht wastewater treatment plant using aerated lagoons process and also comparing the performance of both systems in removing the hormone of est...
