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....

Data envelopment analysis (DEA) is a methodology for measuring the relative efficiencies of a set of decision making units (DMUs) that use multiple inputs to produce multiple outputs. In the conventional DEA, all the data assume the form of specific numerical values. However, the observed values of the input and output data in real-life problems are sometimes imprecise or vague. Previous method...

Among the brilliant contributors to the sciences of medicine, pharmacy, and chemstry during the Iranian era was one genius who seems to stand for his time- the Persian, Razi, (about 865-925 AD), called Rhazes by the western world. The most important authorship of Razi is the "contines" (Alhavi) that in fact, it is a medical encyclopedia and there is the describtion of all the illnesses, the way...

Amaç: Nazopalatin kanalın (NPK) farklı morfolojik tipleri bulunmaktadır. Bu çalışmanın amacı; NPK morfolojisinin konik ışınlı bilgisayarlı tomografi (KIBT) görüntüleri üzerinden olarak değerlendirmektir.
 Gereç ve Yöntemler: Rastgele seçilen 500 hastanın KIBT retrospektif taranmıştır. Sagittal kesit üzerinde yapılan incelemede hastaların yaş cinsiyetlerine göre (silindirik, ağaç dalı, kum ...
