In China, coal combustion to generate electric power is the primary method, the energy-saving and emission reduction is the urgent task. At present, the energy-saving dispatching trial method in some area evaluates energy-saving and emission reduction of coal combustion power generation according to power supply coal consumption rate only. But the power supply coal consumption rate can’t reflec...

according to international trade theories, countries attempt to produce and export commodities with their abundant resources. iran has great energy resources and availability of inexpensive energy input has increased energy consumption per capita in manufacturing sector as well as in consuming sector. relying on low energy price, manufacturers employ energy-intensive methods for producing and e...

BACKGROUND Healthy eating by primary school-aged children is important for good health and development. Schools can play an important role in the education and promotion of healthy eating among children. The aim of this review was to: 1) perform a systematic review of randomised controlled, quasi-experimental and cluster controlled trials examining the school-based teaching interventions that i...

The climate changes as well as the sustainability of our energy supplies present multiple challenges and require a worldwide coordinated response. Europe 2020 is a jigsaw of policies and measures binding targets for 2020 to reduce greenhouse gas emissions by 20%, ensure 20% of renewable energy sources in the EU energy mix, and the reduction of EU global primary energy use by 20%. In the longer ...

unlike other studies in which the autours have focused on testing the existence of an environmental kuznets curve, in this study, causality relationship between the energy consumption (oil equivalent), carbon emissions, gross domestic production, total labor force and fixed capital formation is investigated during 1960 to 2007 in iran. following an examination of stationary tests for all the va...

To address the increasingly important energy efficiency problem, a Standby-Sparing scheme has been studied previously to reduce the energy consumption in dual-processor fault-tolerant systems. However, the dedicated (spare) processor in the Standby-Sparing scheme needs to execute backup tasks at full speed to preserve system reliability and thus cannot effectively exploit its available slack ti...

Energy-aware task scheduling is critical for real-time embedded systems. Although dynamic power has traditionally been a primary source of processor power consumption, leakage power is becoming increasingly important. In this paper, we present two optimal energy-aware polynomial-time algorithms for scheduling a set of tasks with release times, deadlines and precedence constraints on a single pr...

Climate change has become a challenge with adverse impacts on the Earth. Reducing the use of fossil fuel is a primary step to solve environmental problems. As the population continues to rise, to meet the growing demand for construction with a large share in energy Consumption, Efforts to make the built environment more energy efficient is crucial. The main objective of this research is to eval...

Objective: The main objective pursued in this paper is to investigate the energy consumption for drying of potato slices using vacuum-infrared drying method. Methods: Drying of potato slices with the thicknesses of 1, 2 and 3 mm were conducted at vacuum levels of zero (without vacuum), 20, 80 and 140 mm [Hg], infrared radiation at power levels of 100, 150 and 200 W in the three repetition. Resu...
