اسلامی ریاست میں قومی قیادت کے اصول

To serve humanity and nation leadership is a noble and glorious position. Sensible, talented, honest and true leadership not only works honestly with dedication and commitment in solving internal and external challenges, but also plays a key role in the development of peace and prosperity in society. Due to the lack of spirit and training of the people, especially of the younger generation, these incompetent leaders succeed in befooling many people and it transferred from generation to generation, in order to change this scenario, education and training of the young generation is urgently needed. True spirit of leadershipcan be promoted by creating sincerity, awareness in students in the light of Islamic teachings. This article focuses on the Islamic attributes of leadership through which a person can have opportunities to transform social system by bringing reforms and development in social system to perform the duties by guiding and governing people with the noble aim to serve humanity according to modern requirements in the light of the teachings of holy Prophet.

Composite Material Solution for Armoring

Textile composite materials are extensively used for high-tech applications like aerospace, ballistics, automotive, sports, etc. Ballistics are one of the hot research topics owing to the law and order issues around the globe. Conventionally the ballistic composite materials are produced by laminating 2D fabrics. The composite materials fabricated from 3D woven textile reinforcement are widely studied for different applications, but fewer products are being manufactured from them. This research focused to investigate the effect of fillers on the performance of 2D laminated composites and weaving parameters (stuffer yarn count and binding thread density) on the ballistic performance of 3D composite materials. Firstly, the composites were fabricated using silica nano-fillers to reinforce the Kevlar/epoxy composites. It was found that the addition of silica nano-fillers results in the formation of hybrid composite materials that offer improved flexural, tensile and impact properties. Optimum properties were obtained at a filler concentration of 8%. Limited data is available on the properties of 3D woven structures and the associated composite materials. Therefore, the subsequent studies investigated the effect of weaving parameters (stuffer yarn count and binding thread density) on the properties of 3D woven structures. An extensive experimentation was performed to understand the behavior of 3D woven structures using flax fibre, owing to the high cost of para-aramid. Novel hybrid 3D woven structures were produced, and it was seen that increase in stitching points in a 3D structure increase the mechanical properties and energy absorption of the fabric. Similarly, addition of stuffer yarn in the 3D woven structure leads to improved mechanical properties. Based on the performance of the developed composites, structures with better performance were reproduced with para-aramid to fabricate composite materials. The energy absorption behviour of these composite materials was investigated using an indigenously developed setup. The energy absorption was also modelled numerically for these composites to validate the experimental results. It was found that the woven structure with more stuffer yarns and high binding density exhibits better performance and can be potentially used to produce the ballistic vest.
