Hydrophilic fumed silica (FS) and precipitated silica (PS) powders were suspended in mineral oil; increasing the silica volume fraction (φ in the suspension led to the formation of sol, pre-gel, and gel states. Gelation took place at lower φ values in the FS than the PS suspension because of the lower silanol density on the FS surface. The shear stresses and dynamic moduli of the FS and PS susp...
For improving the mechanical and thermal properties of polyurethanes based on glycidyl azide polymer (GAP), a series of polyurethane elastomers with two soft segments were prepared from hexamethylene diisocyanate (HDI) / (GAP) / (PPG) /TMP and isophorone diisocyanate (IPDI) / GAP/ PPG/ TMP formulation. The weight ratio of soft segments GAP/PPG in polyurethane samples is changed as following ord...
Two hundred and ninty four engorged female ticks were collected from 4 different geographical regions for assessment of tick resistance against acaricide compounds.The 15-21 day- old larvae have been tested in accordance with FAO recommended larvae packet test . Resistant factor for each region was calculated by LC50 and LC99. Minimum LC50 (0.008)and, Maximum LC50 (0.024) for Amitraz wer...
in this work dynamic recrystallization behavior of aisi 403 martensitic stainless steel was studied using hot compression tests over temperature range of 900 c -1200 c and strain rate range of 0.001 s-1 - 1 s-1. the obtained flow curves showed that the hot compression behavior of the alloy is controlled by dynamic recrystallization. the flow stress and strain corresponding to the critical, pe...

a small salt gradient solar pond with an average surface area of 1.8 m2 and depth of 0.8m has been tested. the depths of storage, gradient and surface zones are 0.3, 0.27 and 0.07m, respectively. the temperature of the storage zone for the summer days reaches its maximum of 65˚ c after about 8 days. daily variation of the storage zone temperature was about 8˚c which is due to small volume of th...
Groundwater is a major source of drought. Karstic aquifers are important sources of groundwater in the West and Kermanshah province. This study was performed to investigate the effects of the meteorological drought on the karstic aquifer with different conditions of development. The studied areas in this research included two karstic aquifers, Bistoon-Parau and Patagh mountain in Kermanshah pro...
In this paper, the consequences of filled volume on the transient lateral dynamic and stabilities boundaries displacement of an articulated vehicle carrying liquid is investigated. First, a sixteen-degrees-of-freedom nonlinear dynamic model of an articulated vehicle is developed then, using TruckSim software the model is validated. Next, the dynamic interaction of the fluid cargo with the vehic...
