This article aims at contrasting aspectual oppositions in English and Persian in the context of the novel The Old Man and the Sea, and its translation by Daryabandari (1983) as the data. Unlike English, in Persian perfective and imperfective forms are morphologically marked. While the vast majority of English simple past forms are translated into Persian by past perfective forms, only less than...

Security is a crucial property of system behaviour. It generally requires some kind of control over the information ow among parts of the system. In order to analyze these possible ows it has been introduced the Non-Interference (NI) property 7]. In particular NI was introduced to detect all the possible ows from a group of users to another one. A lot of research has been done about NI in the f...

In this article, we examined the behavior of chemical reaction effect on a magnetohydrodynamic Prandtl nanofluid flow due to stretchable sheet. Non-linear thermally radiative term is accounted in energy equation. Constructive transformation is adopted to formulate the ordinary coupled differential equations system. This system of equations is treated numerically through Runge Kutta Fehlberg-45 ...

This paper addresses the combined effects of couple stresses, thermal radiation, viscous dissipation and slip condition on a free convective flow of a couple stress fluid induced by a vertical stretching sheet. The Cogley- Vincenti-Gilles equilibrium model is employed to include the effects of thermal radiation in the study. The governing boundary layer equations are transformed into a system o...
