An experimental and numerical study was carried out to investigate the heat transfer by natural convection in a three dimensional annulus enclosure filled with porous media (silica sand) between two inclined concentric cylinders with (and without) annular fins attached to the inner cylinder under steady state condition. The experiments were carried out for a range of modified Rayleigh number (0.2 ≤Ra*≤ 11) and extended to Ra*=500 for numerical study and for annulus inclination angle of (δ = 0˚, 30˚, 60˚ and 90˚). The numerical study was to give the governing equation under assumptions that used Darcy law and Boussinesq’s approximation and then it was solved numerically using finite difference approximation. It was found that t

impersonality. Such discourse is characterized by the choice of specific vocabulary and syntactic
structures as well. However, there are some tendencies to bring political speech nearer to the
everyday discourse and that is why political speeches have been becoming more informal and
personal. Like any other types of discourse, the American political speeches are loaded with
deictic expressions that form an essential complementary

The research entitled (The Visual Illusion in American Contemporary Ceramics) includes four chapters، the first chapter of which includes the methodological framework for the research، which contains the research problem focused on the following question: Has the American potter succeeded in achieving the artistic and aesthetic In the art of ceramics، as in the art of drawing and graphics، the fact that the art of ceramics has its advantages and limits in terms of material and technology? The aim of the research was to identify visual illusions in visual art in the works of a selected group of American potters. While the importance of the research was evident in that it sheds light on the methods and techniques of optical art in cont
