data envelopment analysis (dea) is a method for measuring the efficiency of peer decision making units (dmus) with multiple inputs and outputs. the traditional dea treats decision making units under evaluation as black boxes and calculates their efficiencies with first inputs and last outputs. this carries the notion of missing some intermediate measures in the process of changing the inputs to...

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...

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...
