One of the future technologies for energy supply in the electricity and automotive industries is the use of fuel cells. Hydrogen is the main source of fuel in fuel cells. Methane reforming through partial oxidation of methane is one of the methods of hydrogen production. In this paper, this process for the production of hydrogen gas, which is the energy source of these fuel cells, is examined n...
Doubtlessly, establishing sustainable growth and development of urban areas is a major goal of policy-makers since a considerable proportion of total population with various levels of income live in such areas. Given the scope and diversity of the economic activities, industrial sector may provide an effective instrument for fulfilling the balanced development of economic activities, which coul...
Regional output per worker has converged across Chinese provinces in 19791989. The estimated rate of convergence is 2.2 percent. This rate of convergence can be explained by neoclassical growth model conditional on assumptions about factor mobility and production elasticities. My empirical results show that capital mobility has been high across Chinese provinces and that the production elastici...
The importance of drug as a valuable export product in the global economy becomes more clear every day. Understanding the problems of exports and factors affecting it, can be an important step to keep Iran’s position in the world markets and further export development of this product.In this study, Iranian pharmaceutical exports’ supply and demand functions were calculated using co-integration ...
This paper estimates the Frisch elasticity of labor supply, which represents the intertemporal elasticity of substitution. Estimation of this elasticity has previously required assuming that utility is either separable between consumption and leisure or quasi-homothetic with respect to leisure. These restrictions are required to generate hours equations in which individual effects, representing...
Based on 3-D elasticity approach, differential quadrature method (DQM) in axial direction is adopted along with Globalized Nelder–Mead (GNM) algorithm to optimize the stacking sequence of a laminated cylindrical shell. The anisotropic cylindrical shell has finite length with simply supported boundary conditions. The elasticity approach, combining the state space method and DQM is used to obtain...
While numerous studies assess the impact of healthcare spending on health outcomes, typically reporting multiple estimates of the elasticity of health outcomes (most often measured by a mortality rate or life expectancy) with respect to healthcare spending, the extent to which study attributes influence these elasticity estimates is unclear. Accordingly, we utilize a meta-data set (consisting o...
In this work, the nonlocal elastic waves in a fluid conveying armchair thermo elastic single walled carbon nanotube under moving harmonic load is studied using Eringen nonlocal elasticity theory via Euler Bernoulli beam equation. The governing equations that contains partial differential equations for single walled carbon nanotube is derived by considering thermal and Lorenz magnetic force. The...
گل محمدی (r. damascena mill.)مهمترین گونه ای است که در تولید گلاب، عطر و اسانس، در صنعت عطرسازی و دارویی کاربرد دارد. با وجود اهمیت عطر گل محمدی، پژوهش های مولکولی و بیوشیمیایی عطر گل این گونه هنوز در مراحل ابتدایی است. در این پژوهش، ویژگی های مولکولی و فیزیولوژیکی تولید عطر در گل محمدی در آزمایش های مختلف مورد بررسی قرار گرفتند. در آزمایش اول، پژوهشی به منظور بررسی تنوع شیمیایی اسانس میان 44 ت...
