this study investigates the amount of suspended solid particles in three drinking water wells, conducted several times per day in the city of mashhad. the results have also been used for the review and optimization of tested hydro-cyclones. for this purpose, 18 different hydro-cyclones, based on the experimental design process of the taguchi method, were designed and the affecting factors were ...

Hydro generation scheduling is a nonlinear programming problem. This paper describes the hydro generation scheduling problem constraints. The optimal hydro scheduling problem is formulated as a large scale linear programming algorithm and is solved using a commercially available linear programming package. The selected objective function requires minimization of demand and generation of a hydro...

hydro-forming is a fabrication process that uses a fluid medium to form a piece by using high internal pressure. in tube hydro-forming, a tubular blank is placed between two dies, sealed and pressurized water injected, deforming the tube walls in the cavity form of the dies. exist several typical hydro-forming processes such as t- shapes, cross-shapes and y- shapes. successful hydro-forming dep...

Voids are extremely important to water science, because their size and connectivity determines the storage and flow of water both above and below the ground surface. While previous formal theories about voids strictly consider holes hosted inside objects, we generalize voids to also include spaces between objects, and distinguish voids in macroscopic objects from those occurring microscopically...

background:   objective: the aim of this study was to investigate the effects of aqueous and hydro-alcoholic extracts of lettuce seed on testosterone level and spermatogenesis.   materials and methods: in this experimental study 24 adult male nmri mice weighing 20-25gr were purchased. animals were randomly divided into 4 groups: controls, hydro-alcoholic (200 mg/kg) and aqueous extracts (50, 10...

persian oak (quercus brantii lindl., the fagaceae family) is a medicinal plant which seed flour is used to treat inflammatory and gastric ulcers by the tribes in southwestern iran. the current study was done to evaluate the effect of hydro-alcoholic extract of q. brantii seed flour for treatment of gastric ulcers induced by ethanol in wistar rats. the hydro-alcoholic extract of q. brantii was t...

The HYDRO mini-application has been successfully used as a research vehicle in previous PRACE projects [6]. In this paper, we evaluate the benefits of the tasking model introduced in recent OpenMP standards [9]. We have developed a new version of HYDRO using the concept of OpenMP tasks and this implementation is compared to already existing and optimized OpenMP versions of HYDRO.

nowadays,it is important to consider environmental issues,as ecological problems and their severe effect intensify in iran,particularly in khuzestan province.the environmental effects of hydroelectric plants are highly regarded due to their significant impact on an extensive area.the lack of safe path for fish passing through the turbines is one of these damages. in order to deal with these cha...
