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 ...

in this study, the essential oil content in the aerial parts of cleome heratensis which is growing in the east of iran was investigated. the aerial parts of the plant were collected from the late august to october 2014, for a total of four harvests (s1-s4). essential oils were isolated by hydro-distillation. the oils were analyzed by gc-fid and 30 constituents, representing 84.93-92.9 % of the ...

hydro-induction sediment discharge technique (hsdt) aims to prevent reservoir sedimentation by withdrawing the discharge water from the reservoir bottom to suck up and discharge sediments, and by inducing vertical vortexes and undercurrents in the reservoir bay to keep sediments agitated and moving. the technique is facilitated with an innovative discharge conduit system having bottom intakes t...

in this research work, it was planned to study influences of hydrothermal treatment temperature, holding time and press temperature on wood density, spring back, moisture absorption as well as dimensional stability of combined-hydro-thermo-mechanically modified poplar wood. wood blocks were treated hydrothermally at temperatures 120, 150 and 180°c for holding time of 0, 30 and 90 min. afterward...

background: coriandrum sativum l. has been recommended for relief of insomnia in iranian traditional medicine. however, no pharmacological studies have yet evaluated its sedative effects. the aim of this study was to determine if extracts and essential oil of coriander seeds have sedative-hypnotic activity.   methods: the aqueous or hydro-alcoholic extracts or essential oil of coriander seeds (...

in saturated soils, heating induces thermal expansion of both grains and the pore fluid. lower thermal expansion coefficient of aggregates results in the increase of pore pressure and reduction of the effective stress besides subsequent volume changes due to the dissipation of pore pressure and heat transfer. dissipation of thermally induced pore pressure with time is a coupled thermo-hydro-mec...
