An analytic study was conducted on coupled partial differential equations. We formally derived new solitary wave solutions of generalized coupled system of Zakharov-Kuznetsov (ZK) and KdV equations by using modified extended tanh method. The traveling wave solutions for each generalized coupled system of ZK and KdV equations are shown in form of periodic, dark, and bright solitary wave solution...

A later stage scores the four cards in your hand together with a card cut randomly from the deck after the discards have been made. The two cards that were discarded are used to form anothe...

The most recent results and some of the open key questions on the evolution of early-type galaxies are reviewed in the general cosmological context of massive galaxy formation.

Hardly could any poet, like Al-Mutanabbi, draw to himself the constant attention of scholars, literary man and poets. In this article, we try to find the secret of the admiration that Al-Mutanabbi’s poetry has won and see why he is one of the most preferred poets and considered the prophet of Arab poets. Scholars have studied this issue from various perspectives. In this article, however, I wil...

The author contends that sex differentials in childhood mortality in Pakistan are a likely outcome of son preference behavior by parents. Consideration is given to the historical improvement in the female disadvantage in mortality, the neglect of female children, gender and class factors, and son preference and high fertility. Data are from the 1981 Pakistan census and other official surveys....

no matter what the extent of effort and diligencr devoted, it seems almost impossible to duely appreciate the role and works of sharif al-razi: in addition to specific and unique features of his time/age which flourished in science,  knowledge, and enlightment, al-razi had his own distinguished poetic personality. though this article we aim at fairly evaluating the genius and talent of al-razi ...
