Global manufacturing businesses have contributed to energy and resource consumption, pollution. Along with governmental legislation, social market pressure that growing as awareness about environmental issues increases. To tackle such problems the study focuses on analysis of direct consequence Green Manufacturing (GM) practices operational performance in industry. A model for evaluating effect...

With prominent environmental pollution and depleted resources, how to coordinate economic growth eco-environmental protection guide green development represented by total factor productivity (GTFP) is an urgent issue. This study aims empirically evaluate the direct effect, indirect spatial spillover effect non-linear of digital economy on using data 284 prefecture-level cities in China. The emp...

The increasing attention towards the environmental impact of IT (information technology) demands reorientation from IT departments. Research has outlined that the importance of Green IT is related to IT business alignment and environmental initiatives while uncertainty potentially derives from missing standards, measurements, or missing internal support for Green IT. We assume that importance a...

background: by decreasing oxidative stress and whereby decreasing insulin resistance, it may be possible to decrease complications of diabetes mellitus (dm). green tea and sour tea contain phytochemicals which have anti-oxidative function. the aim of this study is to compare the effect of sour and green tea consumption on insulin resistance and oxidative stress in dm. methods: this study is a r...
