As an integration of artificial intelligence and advanced manufacturing technology, intelligent has realized the innovation mode created conditions for green development industry. After constructing a theoretical framework between industrial total factor productivity, this paper uses panel data 30 provinces in China from 2006 to 2020, expresses level with robot density, discuss economic effects...
the main goal of this study is to identify the determinants of the energy intensity in the iranian economy using annual data for the period 1974-2012. changes in energy intensity can be seen as related to three factors including price, income, and autonomous energy efficiency improvements (based on technical progress). moreover the role of energy quality in enhancement of total factor productiv...
This study determines the impact of E-commerce (EC) on some of important economic criteria including total factor productivity( TFP) of Iran country as a developing country in comparison with US standard as a developed country through analyzing and calculating interrelated issues.

in the present work, a simple and sensitive method was developed for determination of morphine and heroin using gold nanoparticles as resonance rayleigh scattering (rrs) and colorimetric technique’s probe. synthesized gold nanoparticles by sodium citrate reduction method have a negative charge layer on their surfaces because of self-assembled citrate anions on their surface. binding of morphin...
the purpose of this study was to investigate the effect of task repetition on accuracy of iranian efl learners ’speaking ability. in order to achieve this purpose, a null hypothesis was developed: there is no statistically significant difference between accuracy speaking ability in iranian efl learners by use of task repetition. ; of course i should mention that, beside this null hypothesis, an...
