Using absorption refrigeration cycles instead of vapor compression refrigeration cycles can drastically decrease energy consumption. In these systems, high level of energy consumption is reduced due to the partially elimination of vapor compression refrigeration systems. On the other hand, utilization of waste heat of the plant, which is a very good opportunity for energy saving,  is possible. ...

compressibility factor and viscosity of natural gasses are of great importance in petroleum and chemical engineering. to calculate the natural gas properties in the pipelines, storage systems and reservoirs, the exact values of gas compressibility factor and viscosity are required. a new method that allows accurate determination of compressibility factor and gas viscosity for all types of: swee...

The impending energy and natural resource crisis forces us to research innovative ways of optimizing our resource consumption. Recent studies have shown that a better understanding of an individual’s energy consumption helps people to lower their energy footprint significantly. We propose SPOTLIGHT, a system that profiles an individual's natural resource consumption pattern in real time using w...

abstractmodernism and social class both are categories rose up from the west capitalism system and create somechallenges for the society. the aim of this discussion is explaining the conflict between tradition andmodernism based on one of the main conflict roots which is called class conflict. in the other words, in thisarticle authors tried to indicate that one the creator or accelerating fact...

Abstract Europe is facing an energy crisis caused by the dramatic rise in gas prices. This situation damaging European economy and urgent measures to reduce consumption are crucial short term. paper aims analyse potential contribution of Power-to-Gas strategy Italian Natural Gas (NG) context current crisis. To do so, system has been modelled means EnergyPLAN software. The electrolysers’ install...

As the COVID-19 virus spread over world, governments restricted mobility to slow transmission. Public health measures had different intensities across European countries but all significant impact on people's daily lives and economic activities, causing a drop of CO2 emissions about 10% for whole year 2020. Here, we analyze changes in natural gas use industry distribution built environment duri...
