The interior of giant planets can give valuable information on formation and evolution processes of planetary systems. However, the interior and evolution of Uranus and Neptune is still largely unknown. In this paper, we compare water-rich three-layer structure models of these planets with predictions of shell structures derived from magnetic field models. Uranus and Neptune have unusual non-di...

as a committed writer, najib al-kayl?ni was of the belief that works of art and literature should be used as a means to promote the islamic culture; thus, he regarded writing narratives, in a realistic style, as the need of the arab world and particularly the egyptian society. features which distinguish his works from those written by other writers are the religious hue and spirit of his storie...

the revolution of 1919 and its positive and negative results reflex on the story’s form and subject. in this period, people were interested to draw events and reflect political and social events of society in their works. they want no more to see their desired world in phantom and dream, because their information to problems of society had increased and they had acquired sufficient statement ab...

Koike, K., On a conjecture of Stanley on Jack symmetric functions, Discrete Mathematics 115 (1993) 211-216. The Jack symmetric function J,(x; G() is a symmetric function with interesting properties that J,(x; 2) is a spherical function of the symmetric pair (GL(n, FQ O(n, [w)) and that J,(x; 1) is the Schur function S,(x). Many interesting conjectures about the combinatorial properties of J,(x;...

C. M. Weinbaum [Proc.AMS, 109(3):615–619, 1990] showed the following: Let w be a primitive word and a be letter in w. Then a conjugate of w can be written as uv such that a is a prefix and a suffix of u, but v neither starts nor ends with a, and u and v have a unique position in w as cyclic factors. The latter condition means that there is exactly one conjugate of w having u as a prefix and the...
