سیرت طیبہ پر استشراقی فکر کے اعتراضات کے اسباب و عوامل کا تاریخی و ارتقائی جائزہ

Over the course of time and with the rapid increase in human population need for mutual relations become crucial. Resultantly on behalf of this closeness, separation, anti-standpoints and comparisons also emerged. As the time passed by hatred and hypocrisy and other social vices spread on large scale. Thus human society was waiting for such liberator who may lead and work for the betterment of this society. With the dawn of Islamic civilization all such issues were not only resolved but also provided with a model for containing the difference of opinion and multiple traditions under its unique worldview. Islamic History presents itself as a model where the minorities were provided with the opportunities of participating in political, social, educational and collective affairs. Thus in a society where tyranny, injustice, un-forbearance, religious intensity, terrorism and the activities of violating the human rights were very common, were substituted by the Islamic ideal  of forbearance. It is argued here that the solution of all these issues was only in religion contrary to what is being claimed about an idea of social harmony where religion is not given its due position. Today its our dire need to develop a sense of harmony, modesty, affection and peacefulness among the masses of various religions of Pakistani society. It is further argued that for this very noble cause all the religious scholars and their followers can come forward playing their pertinent role.  

Evaluating the Efficacy of Compacted Clay Liner Ccl for Arid/Semiarid Region

Geotechnical applications are useful for environmental protection of surface as well as ground water by liner system. Use of clay soils in constructing low permeability liners that covers waste containment is common and cost effective. In arid and semi-arid regions, desiccation and shrinkage cracking adversely affect the integrity of compacted clay liners. The technique and methodology of combining sand, cement, polyethylene chips with medium plastic soil was used for the first time in Pakistan. A mixture of sand, cement and polyethylene chips in different proportions with medium plastic clay has been proposed to reduce the shrinkage potential of medium plastic clay. The basic purpose of this soil modification is to control the volumetric shrinkage of medium plastic clay. The polyethylene bags from garbage dumps were reused for making polyethylene chips, which will not only reduce environmental hazardous waste but also provide a useful additive for controlling soil shrinkage. It was hypothesized that combined effect of sand, cement and polyethylene chips would control the shrinkage potential of soil. The study entails characterization of soil, interaction with synthetic leachate, soil treatment in two phases and effect of leachate on treated soil. About three hundred specimens through forty five different combinations of sand, cement and recycled polyethylene chips were used to optimize volumetric shrinkage and compressive strength properties of soil. The study also evaluates the effect of synthetic leachate on soil samples. Microstructural analysis including Energy Dispersive X-Ray, X-Ray Diffraction and Scanning Electronic Microscopy were used to evaluate the efficacy of treated soil. The combination of additives with medium plastic soil not only reduced the volumetric shrinkage and permeability but also improved the unconfined compressive strength of treated soil. Regression based statistical analysis results revealed that fair correlation exists between mixture of medium plastic clay, sand, cement, polyethylene chips and volumetric shrinkage.
