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. Data are from the 1981 Pakistan census and other official surveys....
sio2-supported silyl chromate catalyst is an important industrial catalyst for production of high grade hdpepipe materials. the control of the short chain branch (scb) distribution using this catalyst system is still a greatchallenge. in this work, ethylene and 1-hexene copolymers were synthesized using sio2-supported silyl chromatecatalyst combined with triisobutylaluminium (tiba), triethylalu...
health status of individuals and organizations allows expected to have higher performance. due to the fast moving world of today's globalization managers to have a healthy organization must be equipped with a weapon called cultural intelligence. cultural intelligence as an ability to function effectively in different cultural environments is defined.this study examines the effects of cultu...
In this study, a wide range of combined ageing treatments and cold work deformations in the Al 4.2 wt% Ag alloy matrix were proposed, aiming to investigate the effect of defects such as precipitates (Ag2Al plates) and dislocations on the mechanical and electrochemical behavior of Al–4.2 wt% Ag alloys. Further reductions of thickness from 10 to 60%, decreases the mean size of Ag2...
This paper begins a series studying D-modules on the Feigin-Frenkel semi-infinite flag variety from the perspective of the Beilinson-Drinfeld factorization (or chiral) theory. Here we calculate Whittaker-twisted cohomology groups of Zastava spaces, which are certain finite-dimensional subvarieties of the affine Grassmannian. We show that such cohomology groups realize the nilradical of a Borel ...
