The transport of anthropogenic constituents by runoff from urban roadways can adversely impact the quality of adjacent receiving waters and soils. Metal elements are the most persistent constituents found in pavement runoff. A section of urban highway pavement in Cincinnati, Ohio, USA with an average daily traffic count of 150 000 vehicles was instrumented to sample lateral sheet flow from the ...

In many 3-D forging simulations, the master-grid method or uniform-grid method is adopted as an effect tool for hexahedral element mesh generation, because the method is robust and reliable to construct the intermediate mesh during forging simulation. However, almost equalsized element mesh is employed regardless of the local characteristics of the deforming region. In order to overcome this dr...

This research explored the feasibility of using portable X-ray fluorescence (pXRF) spectrometry to quantify Fe, Cu, Zn, and As concentrations in dried ground organic materials (fungi, vegetation, animal tissues) with intermediate thickness.

a palladium composite membrane was prepared via electroless plating technique using organic-inorganic method during activation process. the ceramic support surface was modified by two tio2-boehmite and one γ-alumina layers to avoid pd penetration in support pores. thin and defect-free pd composite membrane was obtained by creating a relative smoothness on the ceramic support and using pd nanopa...

this paper tries to analyze the impacts of intermediate goods trade on production, consumption, investment, net exports, employment, labor wage and capital rent of iran in its bilateral trade relations with china. this analysis has been done by modeling, solving and calibrating an international real business cycles (irbc) model in period 1980-2009. the results show that when elasticity of subst...

telegram is now considered as one of the most famous platform online social networks among media university students. nowadays, the immense popularity of social networking websites such as telegram has created new opportunities for english learners. accordingly, the present study aims to investigate whether telegram would be an effective and easy learning tool of vocabulary for iranian female e...

molecular dynamic simulation is a powerful method that monitors all variations in the atomic level in explicit solvent. by this method we can calculate many chemical and biochemical properties of large scale biological systems. in this work all-atom molecular dynamics simulation of polyalanine (pa) was investigated in the presence of 0.224, 0.448, 0.673, 0.897 and 1.122 m of guanidinium chlorid...

the present study investigated efl teachers’ beliefs about oral corrective feedback (cf), their cf-provision practices across elementary and intermediate levels, and their beliefs-practices correspondence. to this end, the researchers conducted a semi-structured interview with the teachers and went on an overall forty-hour observation of their classrooms across both levels. the findings reveale...

The traditional element-based topology optimization based on material penalization typically aims at a 0/1 design. Our numerical experiments reveal that the compliance of smooth design is overestimated when properties boundary intermediate elements under fixed-mesh finite element analysis are interpolated with model. This paper proposes floating projection (FPTO) method for seeking using ersatz...
