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...

Data are from the 1981 Pakistan census and other official surveys....

Weke hemû edebiyata cîhanê, yek ji mijarên sereke yên berhemên ku bi zaravayên cuda Kurdî hatine nivîsandin jî mijara eşq e. Ev têgeh di cureyên de, çerçove û wateyên de hatiye bikaranîn.
 Yek wan edebî navborî Perîşanname ye aliyê Mela Perîşan Dinewerî ve sedsala nehem a hicrî awayekî helbestkî, nivîsandin. Di berhema em dikarin wekî dînî yê bihesibînin, şair têgeha eşqê li hember aqil da...

comparing the islamic logic and jurisprudential principles, and basedon the separation between minor and major authorities (hujjiyyatsughrawi wa kubrawi), it can be proved that (1) minor authority ofsuitable verbal text per nexum (al-mantuq al-muwafiq al-iltizami),minor authority of suitable concept per nexum (al-mafhum al-muwafiqal-iltizami), and minor authority of contrary concept (al-mafhum ...
