The purpose of this paper is to explain the causes of long-run movements in the parallel market premium in the pre-and-post revolution Iranian economy. The paper suggests that the premium is affected by both real and monetary shocks. Non-spurious co-integration results indicate that negative oil revenue shocks and a revolution-induced exogenous capital outflow caused the parallel market paralle...

up to now, studies of mirza agha tabrizi's works (a pioneer of iranian drama) have been carried out from the perspective of the evolutionary history of drama in iran. but this paper explores the enlightening aspects of these texts about social life in iran before the constitutional revolution. furthermore, the present study discovers a potentially aesthetic revolution in these works. by ma...

Core-shell nanostructures are emerging as more important materials than alloy nanostructures and have much more interesting potential applications in various fields. In this work, we demonstrated the fast and facile synthesis of core-shell nanoparticles consisting of Pt thin layer as the shell and Ni nanoparticles as the cores. The described method herein is suitable for large-scale and low-cos...

axial vibration effect of shell particles on dynamic stability of a cantilevered cylindrical shell under an axial follower force was addressed. in spite of free-ended shells, the reduced axial force under this effect cannot be derived analytically. instead, an approximate method was proposed based on the fact that the static (and harmonic) axial deformation under an axial load in a free-ended b...

introduction breeding quail and quail egg industrial production because of the high nutritional value of these products has been developing these years. considering the high demand and economical production, further development in the future is predicted. in order to design and effective utilization of the equipment for transportation, separation, packaging and storage, the physical and mechani...

We propose a mathematical model of vibration elastic systems formed by conjugated shells revolution with different geometry in the field combined static axisymmetric loads. The is based on concepts geometrically nonlinear theory mean bending and realized within framework classical Kirchhoff–Love use contemporary methods applied mathematics numerical analysis. spectral picture shell structure el...
