On A Kp Class Of Partial Differential Equations Conservation Laws And Solitary Wave Solutions
(
Qatar University
, 1996 , Article)
It is shown that a KP class of partial differential equations possesses an infinite number of conservation laws. In addition, exact and explicit solitary wave solutions are constructed for the KP class of equations, which ...

Photo-interpretation of Landsat MSS images of Qatar Peninsula reveals several surface lineaments of different types, extentions and trends. Some of these photo-lineaments are of structural nature while others represent ...
Characterization of Polymers in Dilute Solutions
(
Qatar University
, 1997 , Article)
Basic moleculer characterisitics of polymers are: molecular architecture, molecular weight and size, and their distributions. All these characterisitics are derived from measurements of very dilute solutions. Methods of ...
