mithraism and zoroastrianism, the ancient iranian religions, are rooted in the culture of this country; consequently, their reflections are vividly evident in persian literature. the prominent iranian poet nizami ganjavi utilized these cults allegorically and symbolically in his two prominent versified stories of haft paikar, and khosro and shirin. this paper aims at discussing the primary samp...

The results of a complete and sensitive X-ray survey of all known stars of spectral type A, F, and G in the immediate solar vicinity with distances less than 13 pc are presented. The X-ray data were obtained primarily from the ROSAT all-sky survey (RASS); those program stars not detected in the RASS data, were subsequently studied in the ROSAT pointed observation program. The detection rate amo...

one of the distinctive manifestations of odes at age of is jahelid is depiction and description of ridding animal for the jahelid arabic man in general and camel in particular, that is friend, attendant and associate for the poet and apparently by allusive borrowing from limbs of symbolic animals like zebra, ox and ostrich etc he/ she has sparsely illustrated it. unlike the technique adapted by...

In the past decade, helioseismology has revolutionized our understanding of the interior structure of the Sun. In the next decade, asteroseismology will place this knowledge into context, by providing structural information for dozens of pulsating stars across the H-R diagram. Solar-like oscillations have already been detected from the ground in a few stars, and several current and planned sate...

Abstract: In this paper, we demonstrate the effectiveness of the (G ′ G )-expansion method by seeking more exact solutions of the SRLW equation, the (2+1) dimensional PKP equation and the (3+1) dimensional potential-YTSF equation. By the method, the two nonlinear evolution equations are separately reduced to non-linear ordinary differential equations (ODE) by using a simple transformation. As a...

today, knowledge is considered as a competitive advantage. so, different countries try to prepare necessary infrastructure for knowledge development in different levels. one of the solutions in this field especially for know-how development is establishing physical places with purpose of doing knowledge based projects. these physical places were established in different countries with various n...
