in the face of limited water resources, better utilization and operation of irrigation networks is essential. use of control systems is considered as one of the most assured ways to achieve the aim. in the course of the present study, two centralized controllers are applied to the west canal of aghili irrigation district in i. r. iran. the proposed control algorithms consist of a distant downst...

tehran has been facing water shortage challenge for decades and it has not hesitated to exploit neighboring watersheds. rising demand and limited resources might make water crisis a strong possibility in the near future. an accurate and applied analysis of tehran's urban water system (uws) would be the first step to be taken to prevent such a crisis. this research is an effort to make an a...

in today’s world renewable energy is highly demanding because of increasing oil and fuelprices, desire and necessity to avert irreversible climate damage and also the unreliability of the non -renewablesources. in renewable energy, water is an important source. previously water is used only for survivalof human being as much as food but no attentionhas been givenen to economical use and conserv...

In this paper, polyacrylamide/chromium acetate gel polymer system was prepared as water shut-off system to control water production in one of the Iranian oil reservoirs condition. Effect of various parameters such as temperature (90 °C) and water formation from view point of salinity and divalent cations, was evaluated on the gelation kinetic and gel strength using bottle testing method. Th...

the contact between major settlements in the central plateau of iran, especially in desert areas, was not possible without having a secure communication system. in this regard, designing communication networks through constructing secure roads with halfway caravansarais in desert areas, usually without secure underground and surface water supply, needed special insights and provisions. iranians...

serum albumin is the most aboundant protein in blood plasma. its two major roles aremaintaining osmotic pressure and depositing and transporting compounds. in this paper,albumin-methanol solution simulation is carried out by three techniques including montecarlo (mc), molecular dynamic (md) and langevin dynamic (ld) simulations. byinvestigating energy changes by time and temperature (between 27...

a long-term field experiment was conducted for 7 years to evaluate the effect of different amendments to mitigate the adverse effect of saline-sodic water in a calcareous soil under cotton-wheat cropping system. the pooled results over 7 years revealed that the application of saline-sodic water decreased the mean cotton-seed yield by 20.7% as compared to good quality canal water. however, wheat...
