In this thesis the transport of nanofluid along with heat transfer towards the stretching surface is investigated. The boundary layer flow of nano and hybrid nanofluids is examined towards stretching surface by considering three distinct cases namely; plane sheet, hollow cylinder and curved sheet. These stretching flows are encounter in aerodynamics, plastic sheet extrusion, continuous stretching of plastic films and artificial fibers. The complex governing system is simplified by employing similarity analysis and the transformed non-linear system of equations is solved numerically through well established and stable computational techniques via computational software MATLAB. The numerical procedures of authenticity are performed by means of grid independence test. The validation of the numerical results is carried out by comparison with the available literature in a limiting sense and an excellent match is attained. The influence of emerging physical parameters on fluid flow, temperature, instigated magnetic field, skin friction coefficient and Nusselt number are analyzed through graphs, bar charts, and tables. One of the notable findings includes that the thermophysical characteristics of nanoparticles and surface curvature have a dominant effect on velocity and temperature distributions.

محمد نعمت اللہ ارشد گھمن
ادب انسانی زندگی کی عکاسی کرتا ہے۔ ہر انسان کی پہچان معاشرے سے ہوتی ہے اس لیے ادب اور معاشرہ باہم لازم و ملزوم ہیں۔اردو زبان کی تاریخ زیادہ قدیم نہیں ہے۔ تخلیق کارانسانی زندگی کے فہم کا دوسرا نام ہے اسی طرح نقاد تخلیق کاروں کی الجھی ہوئی گتھیاں سلجھاتا ہے۔وقت گزرنے کے ساتھ ساتھ اردو شاعری کے علاوہ اردو نثر کے دائرے بھی وسیع تر ہوتے جا رہے ہیں۔پاکستان بھرکی جامعات میں ایم فل اردو اسکالرز کے لیے سب سے بڑا مسئلہ ان متنوع موضوعات کے حوالے سے مواد کا حصول ہے اور ان کا بہت زیادہ وقت اسی میں ضائع ہوجاتا ہے۔اسی بات کو مدنظر رکھتے ہوئے اس کتاب کو پایہ تکمیل تک پہنچایا گیا ہے۔ ایم فل اردو کے مباحث پر اس سے پہلے کوئی کتاب میری نظر سے نہیں گزری اسی وجہ سے غالب امکان ہے کہ تحقیق کے طلبا کے لیے یہ کتاب آب حیات سے کم نہیں ہوگی۔
اس کتاب کی تیاری میں مجھے اپنے اساتذہ ڈاکٹر مشتاق عادل، ڈاکٹر محمد یوسف اعوان، ڈاکٹر محمد عامر اقبال، ڈاکٹر یاسمین کوثر،ڈاکٹر عبدالستار نیازی،ڈاکٹر قیصر آفتاب، ڈاکٹر عظیم اللہ جندران، میڈم ماریہ بلال کے علاوہ ہم جماعت صائمہ اختر کی بھرپور معاونت اور تعاون شامل حال رہا۔میں سب سے زیادہ اپنی شریک سفر کا ممنون ہوں جنہوں نے میرے تحقیقی اور تخلیقی سفر میں ہمیشہ آسانیاں پیدا کیں۔کوئی بھی بات یا تحریر حتمی نہیں ہوتی، اس کی بہتری کے دروازے ہمیشہ کھلے رہتے ہیں۔ قارئین کی آرا اور ناقدین کے مثبت تبصروں سے اس کتاب کا آئندہ ایڈیشن بہتر انداز میں سامنے آ سکے گا۔

صارفین کے حقوق: معاصر پاکستانی قوانین اور سیرت نبوی ﷺ کا تقابلی مطالعہ

In order to protect consumer rights, the government has made regular legislation on national and provincial level. In which the rights of the consumers are clearly explained. These rules are contemporary and comprehensive, those who are more likely to ensure the protection of consumer rights. With the help of these laws, different issues and conflicts of consumers can be resolved. The Sharia, the rights reserved for the users/consumers are also of a wide variety. In this article first the contemporary laws of Pakistan about the consumers protections has been explained and then in the lights of Saying of Muhammad (PBUH) the rights of users and consumers have been mentioned in details, in the last the comparison of the both laws is presented.

پاکستان میں اردو زبان کی تدریس کے مسائل و مباحث

Language is a means of communication. Language is the recognition of a nation and the custodian of the culture in a society. Among the various languages of Pakistan, Urdu enjoys a unique status as national language. It is not only a lingua franca but also a means of unifying the whole nation as well. Urdu is taught as a compulsory subject up to higher secondary level. Teaching of Urdu language has been a very chronicle problem since long. A general outcome shows that Urdu is taken for granted as an easier subject, so no extra measures and arrangements are made in its teaching. There was a dire need to review this problem in order to find out the remedial measures. This research is an effort to find a clue for the said purpose. The research study includes both pedagogical and linguistic aspects keeping in view the ground realities. The first chapter deals with a comprehensive introduction and teaching importance of Urdu language whereas the second chapter relates to the pedagogical concepts associated with its teaching. Third chapter deals with the skills covering listening, speaking, reading and writing problems faced by the learners residing in all the areas of this country. Fourth chapter follows the art of written mode, punctuation, annotation and pronunciation problems. Fifth chapter deals with teaching of prose, poetry, grammar and composition. An overall summary and analysis has been given in the last chapter. Besides this, it includes conclusions and recommendations for the improvement of existing situation and further research. I hope this research may prove a useful addition in the realm of teaching Urdu as a language.
