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...

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.
