with the increasing world population and limitations on arable land, increasing the yield per unit is one of alternatives human food supply. greenhouse cultivation as one ways of increase the performance can arrive this purpose. but the energy restriction of another human challenges, so that increase the performance without considering energy consumption almost appears to be meaningless. due to...

conclusions this study showed a high prevalence of energy drinks consumption among youth. the current results highlight the importance of education to prevent the consumption of energy drinks in excessive quantities and modifying some wrong perceptions regarding the benefits of energy drinks in youth. patients and methods a pilot cross-sectional study survey was undertaken on students aged betw...

steel industry is one of the most consumption of energy in the world, which is related to melting furnace which result environmental pollution. we calculate the energy consumption and capital cost of dust collectors of venturi scrubber (vs) and electrostatic precipitator (esp) which are connected to melting furnace in respect to industrial ecology for selection of appropriate dust collection sy...

in this study, 10 normal volunteers and 5 sports-trained paraplegics with lesions between t6 and l2 were studied whilst walking with axillary crutches and knee-anlde-foot orthoses. all subjects walked at their preferred speed on a figureof- eight track. normal subjects also walked at slower and faster speeds. oxygen consumption, heart rate and rating of perceived exertion were measured. in norm...

this paper investigates the possibility of both linear and nonlinear effects of energy consumption on economic growth in iran, using data for the period of 1959–2007 based on threshold regression. some previous studies support the view that energy consumption may promote economic growth. however, the conclusion drawn from this study suggests that such relationship exists only where there is a l...

in the recent years, renewable energy sources are an important component of world energy consumption. gdp is one of the main measures of a country’s economic activity. most of the studies examine the impact of renewable energy consumption on gdp with single equation model and the others use dynamic panel data. since the granger causality analysis’s findings of this paper establish bidirectional...

today, one of the biggest problems that gripped the banking sphere, the high cost of implementing advanced technologies and the efficient use of the hardware. cloud computing is the use of shared services on the internet provides a large role in developing the banking system, without the need for operating expenses including staffing, equipment, hardware and software reducing the cost of implem...
