Extant Green IT practices and reports reveal that many organizations implementing Green IT face the problem of sustaining Green IT initiatives to gain long term advantage. This study attempts to address the issue by proposing a sustainability model for Green IT initiatives. It evaluates longitudinal changes in Green IT environmental performance of 24 firms featured in the top Green IT rankings ...

This study considers priorities of primary goals to increase policy efficiency of Green ICT. Recently several studies have been published that address how IT is linked to climate change. However, most of the previous studies are limited to Green ICT industrial statute and policy directions. This paper present Green ICT policy making processes systematically. As a result of the analysis of Korea...

abstract today, the concept of a city without green spaces in any shape is not imaginable. by the results of a city development and their ecological complexity, the existence of green spaces and their development have been inevitable forever. in recent research, the condition of the green space in firoozabad city has been studied. the methodology in this research is descriptive-analytical and a...

This paper reports the transient photoluminescence (PL) properties of an InGaN/GaN multiple quantum well (MQW) light-emitting diode (LED) with green emission. Recombination of localized excitons was proved to be the main microscopic mechanism of green emission in the sample. The PL dynamics were ascribed to two pathways of the exciton recombination, corresponding to the fast decay and the slow ...

to evaluate the most suitable method as well as different conditions of blanching in the process of green tea production from local tea green leaves, this research was conducted in split plot in time and on the basis of a randomized complete block design of six treatments in 3 replications (different plucking times). two common methods of blanching by steaming and panning were used. green leaf ...

In this study, an efficient and green process for the synthesis of dihydropyrimidin-2(1H)-ones from aromatic benzaldehydes, ethyl acetoacetate and urea using Al-MCM-41 as heterogeneous catalyst and microreactor under solvent-free conditions has been developed. The advantages of this method are easy work-up procedure, regeneration of the catalyst, clean and neutral reaction conditions.

A composite foam of polyurethane/chitosan with chitosan content of 20 wt% was successfully prepared as an adsorbent for the removal of malachite green from aqueous solution, the structures and properties were characterized by scanning electron microscope and Fourier transform infrared spectroscopy. The results showed open cell content of polyurethane/chitosan was more than 95% and open cell str...
