abstract i n this paper we investigated total energy consumption and its individual forms (oil, natural gas, electricity, renewable energies and coal) relationship with real gross domestic product (gdp) in iran. we employed hsiao’s (1981) methodology and annual data which cover 1967-2010 for investigation. the empirical findings indicate there is bidirectional causality effect with real gdp and...

abstract in order to assess the environmental impact of agricultural activity, the long-term sustainability should be considered. in order to achieve solutions to reduce energy consumption and carbon emissions in the production of rainfed sunflower, this assessment was conducted in the north east of iran. four production methods, i.e. conventional tillage (ct), tow reduced tillages (rt1and rt2)...

typically, two configurations are used for energy harvesting, with different advantages: piezoelastic and piezomagnetoelastic. best performance of piezoelastic configuration is limited to its narrow bandwidth around the resonance frequency. if the excitation frequency slightly deviates from the resonance frequency, the power-out is severely reduced. to overcome this, the piezomagnetoelastic has...
