As researchers involved in chromatography for 30 years we would like to present three approaches of implementation of principles of green chemistry into gas chromatography.

the purpose of this paper is to investigate causality relationship between emission of carbon dioxide, the level of national income and energy consumption in iran consumption of fuel fossil as an input of production or as a final consumption which produces significant amount of pollution such as green house gases in the world. c02 emission is the most important green – house gases which has the...

The Climate Group notes that energy consumption by ICT activities represented 2 % of global human activity in 2009 [1]. ICT is therefore a sector contributing both to natural resource depletion and to greenhouse gas emission. Moreover, ICT generates considerable quantities of electronic waste, it emits radio waves (including GSM and WiFi) that can adversely affect human and animal health, and i...

To overcome many-query optimization, control, or uncertainty quantification work loads in reliable gas and energy network operations, model order reduction is the mathematical technology of choice. this end, we enhance model, solver reductor components morgen platform, introduced Himpe et al. [J. Math. Ind. 11:13, 2021], conclude with a mathematically, numerically computationally favorable mode...

This paper reviews the greenhouse gas emissions of prefabrication elements for residential development in Hong Kong. Prefabrication becomes a common practice in residential development in Hong Kong and is considered as a green approach. In Hong Kong, prefabrication took place at factories in Pearl River Delta. Although prefabrication reduces construction wastage, it might generate more greenhou...

In this paper, an Adaptive-Network-based Fuzzy Inference System (ANFIS) is used for forecasting of natural gas consumption. It is clear that natural gas consumption prediction for future, surly can help Statesmen to decide more certain. There are many variables which effect on gas consumption but two variables that named Gross Domestic Product (GDP) and population, are selected as two input var...

in this work, response surface methodology (rsm) and artificial neural network (ann) were used to predict the decolorization efficiency of reactive red 33 (rr 33) by o3/uv process in a bubble column reactor. the effects of four independent variables including time (20-60 min), superficial gas velocity (0.06-0.18 cm/s), initial concentration of dye (50-150 ppm) and ph (3-11) were investigated us...

Local city authorities are making a serious effort to expand the number of low-greenhouse gas vehicles (green vehicles) at home. There is no reliable methodology , however , to support the implementation of this passenger transportation concept. In order to optimize the green capacity , a system has been developed to support decision making in urban green vehicle routing. The objective of this ...
