Cross-country data on energy consumption, GDP and vulnerability are used to measure percentage changes in vulnerability associated with percentage changes in per capita GDP and per capita energy consumption. Energy consumption, through its nonlinear effects on per capita income, have the effect of reducing a country’s overall vulnerability to climate change by a greater amount at moderate incom...

predation rate is basic to any investigation of prey-predator interaction and a major component in the selection of predators for biological control. the predation rate of variegated lady beetle, hippodamia variegata (goze), fed on different densities (20, 40, 60, 80 and 100) of third instar nymphs of cotton aphid, aphis gossypii glover, was studied under laboratory conditions (25 ± 1 °c, 65 ± ...

In the new era of ICT, cloud computing is in demand. As cloud usage increases day by day, energy consumption required for its infrastructure also increases drastically. So it is critical to study energy consumption in cloud system infrastructure. Green Cloud Computing is the need in industries and research areas. GCC has become critical focus on economic and environmental policies of the countr...

the growth of the electrical energy consumption form one side and the bounded available fossil fuel and other limitations from the other side, makes the thermal power plants upgrading as a main demand in the world. decreasing the internal energy consumption, increasing the performance and the output power with the minimum costs are the important targets of the power plants retrofitting. nowaday...

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...

Fiber thermomechanical refining is a critical step for the manufacturing of medium density fiberboard (MDF). To increase productivity and improve fiber quality with a reduction in energy consumption during refining, it is essential to determine appropriate refining conditions, such as the chips retention time (accumulated chip height, CH) in the pre-heater, feeding screw revolution speed (SR) i...

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...

An increasing attention has been dedicated to the innovation in methods and approaches in tackling energy consumption issues. Among these, the Practice-oriented design approach, combined with Living Lab concept, seem to have a considerable innovation potential for the consumption reduction. In this paper I will analyse these approaches with a specific focus on the role of the body and implement...

Load side management is the basic and significant principle to keeping the balance between generation side and consumption side of electrical power energy. Load side management on typical medium voltage feeder is the power energy consumption control of connected loads with variation of essential parameters that loads do reaction to their variation. Knowing amount of load's reaction to each para...
