Mantle wedge regions in subduction zone settings show anomalously high electrical conductivity (~1 S/m) that has often been attributed to the presence of aqueous fluids released by slab dehydration. Laboratory-based measurements of the electrical conductivity of hydrous phases and aqueous fluids are significantly lower and cannot readily explain the geophysically observed anomalously high elect...

SPARG/AIRFIX is developed by Mohtar and Rahbeh in 2001 as a practical unsaturated flow and multiphase transport model that can be used for the design and operation of sparging and soil vapor extraction systems [5]. The model uses first order kinetics to represent the mass transfer among the aqueous, gaseous, solid, and NAPL phases. The theoretical basis of the model is build on the fact that so...

Abstract Irradiated fuel based on UO 2 is expected to be disposed of in an underground repository according a “once-through” cycle policy. In addition, those countries that have chosen reprocessing their irradiated will also need this kind repository. There international consensus option as the best dispose properly high-level waste. multiple-barrier concept repository, pellet first barrier rel...

The medicinal plant Olea europaea L. is a valuable one whose fruit and its oil are considered as food. There are some reports in ancient medical literature that aqueous extract of its leaves has analgesic effects. This prompted us to investigate the analgesic effect of aqueous extract of its leaves using formalin and tail-flick tests. For this purpose, male NMRI rats weighting 220-260 g were us...

Purpose: To investigate the effect of the aqueous extract of Achillea millefolium on recognition memory in mice. Methods: Male mice (35) were used. The aqueous extract of A. millefolium was prepared using a Soxhlet apparatus and injected intraperitoneally in a dose of 50, 250, 500 or 1000 mg/kg daily for 20 days. The control group was treated with saline 1 ml/mouse/day. Tactile learning was ass...

Color metallography is a useful method for characterizing microstructures of steels with multiple phases. In this paper, application of three different color etching techniques for a bainitic-martensitic steel is reported. Comparisons between the results showed that 10% Na2S2O5 aqueous solution was the best etchant for distinguishing martensite, bainite and ferr...
