C orporate governance structures in the wake of observed differences in firm ownership structures in developed markets and emerging market economies are distinct. In this paper, we examine the effect of an ownership structure of firms on the market reaction to corporate news flows in the context of emerging market economies like India. We observe the price and volume movements associ...

Abstract Vortex pumps are usually designed based on its inner flow model. Currently, the models of vortex pump just consider rate at design condition, which results in low efficiency under off-design rates practical engineering. Therefore, main objective this article is to build a model that takes into account impact rates. To reveal mechanism pump, we provide refined field simulations for pump...

before making decisions about the investment and financing the companies. it is necessary to know how the value of a company is determined. in this article three valuation methods are discussed: 1) value dirver method. 2) free cash flow method 3) economic value added method. in these methods the factors affecting the value of companies such as operating rate of return, cost of capital. amount o...

In this paper, a numerical study has been carried out for coupled mass, momentum and heat transfer in the field under effects of natural convection. For this purpose, the unsteady incompressible Navier-Stokes equations with the terms of the Buoyancy forces (due to temperature gradients), energy conservation and concentration (mass) transfer equations have been simultaneously solved using approp...
