In this thesis, the problems of flow and ion-induced deformation of soft porous bi ological tissues have been examined by using continuum mixture theory approach. In particular, we focus on the tissue deformation due to non-Newtonian fluid and externally applied magnetic field. In this regard, we first analyze the problem of non-Newtonian flow-induced deformation from pressurized cavities in absorbing porous tissues. Specifically, a model with a spherical cavity embedded in an in finite porous medium is used to find fluid pressure and solid displacement in the tissue as a function of non-dimensional radial distance and time. The governing nonlinear equations have been solved numerically to highlight effects of various emerging parameters. Furthermore, based on the geometry of the previous prob lem, the effect of the externally applied magnetic field on flow-induced deformation of absorbing porous tissues is investigated. A biphasic mixture theory approach has been used to develop a mathematical model. The governing dimensionless equations for fluid pressure and solid displacement have been solved numerically using the method of lines approach and the trapezoidal rule, respectively. The effect of magnetic parameter on fluid pressure and solid displacement is illustrated graphically. Finally, the problem of ion-induced deformation of articular cartilage with strain-dependent nonlinear permeability and magnetohydrodynamic effects is presented. The governing set of coupled partial differential equations are non dimensionalized using suitable dimensionless variables. Analytical solutions are provided for the constant permeability case whereas for the nonlinear permeabil ity case the displacement equation is solved numerically using the method of lines technique. The influence of magnetic and permeability parameter on solid dis placement and fluid pressure is illustrated graphically. In some cases, a graphical comparison to the previously reported literature is also presented.

ہم سے درویش کوئی مال نہ زر رکھتے ہیں

ہم سے درویش کوئی مال نہ زر رکھتے ہیں
کوئی دیوار نہ در اور نہ گھر رکھتے ہیں

یہ بھی سچ ہے کہ نہ ہم بال، نہ پر رکھتے ہیں
جاری ہم پھر بھی وفائوں کا سفر رکھتے ہیں

رکھتے بے تاب ہیں دل، آنکھ کو تر رکھتے ہیں
مرے حالات مجھے زیر و زبر رکھتے ہیں

چاکِ دامان لیے خاک بسر رہتے ہیں
تیرے دیوانے کہاں اپنی خبر رکھتے ہیں

اُن کے تُو میرے خدا! خیر سے سینے بھر دے
میرے احباب کہ جو سینوں میں شر رکھتے ہیں

روٹھنے والے بھلا بیٹھے ہیں تائب ؔہم کو
روٹھنے والوں کو ہم یاد مگر رکھتے ہیں

معالم السنن میں امام خطابی كا منہج و اسلوب

The status of Ma'Iim-us-Sunan is very high in explanations of Sunan Abu Dawood because it is considered first an explanation of Sunan Abu Dawood. Imam Khattabi has adopted such a fine method in it that with the literal explanation of words and description of jurisprudential commandments, he has also collected in it sayings ofSalaf-us-Saalih, Arabian proverbs, different opinions of various scholars, grammatical rules and Jarh-o-ta'deel etc. To add, he, as a specially, Ahadith and quotations ofSahabah and scholars, has made provision to describe his chain of narrators. Due to this, the book has adopted the basic primary status of Hadith knowledge. And further, because of these chains of narrators, this book has adopted the form of reference source in matters of teachers' identification of Imam Khattabi. Due to all these qualities undoubtedly the way this book was a need of scholars and researchers of every era, in the same way, scholars can never be exempted from this today.

دیوان نور احمد چشتی

Editing of Deevan-e-Chishti and a comprehensive research on his Deevan has a purpose that is attainment of M.Phil Degree. The work, being a very significant discipline, is to pass on the true spirit with its all realistic approaches to the next generation. Molvi Noor Ahmed Chishti belonged to Punjab. His era was important regarding Urdu Poetry. It was the time when Urdu Poetry had established a strong tradition in Delhi and Lukhno. But, in Punjab, Urdu Poetry was bereft of true patronage because the then non-muslim regime was partial to other languages. In those circumstances, the father of Moulvi Noor Ahmed Chishti. Moulvi Ahmed Bukhsh Chishti Yakdil had been striving for the establishment of a society where Muslims, important branches of knowledge like history, comprehension of Din and literature could get their esteem and status. Yakdiln was successful enough in winning a keen interest of his students towards Urdu and Persian Poetry and prose. He successfully produced such a devoted group of his students who made Punjab, Delhi, and Lukhno important places for the nourishment of Urdu prose and poetry. Moulvi Noor Ahmed Chishti, Amarnath Akbari, Facieer Noor-ul-Din Munnawar, Anwar Hussain Huma and Ghulam Hussain Khurrum are some prominent names in this regard. Literary circles of Delhi felt deeply indebted for their contribution. The last Mughal Emperor Bahadar Shah Zafar conferred Moulvi Ahmed Bukhsh with the title of ' Fakhar-ul-Shu'ara' and he was awarded with seven-pieces `Khila'at'. Moulvi Noor Ahmed's prose work, research and Yaadgar-e-Chishti are his valuable contributions. His poetic work has been edited in the light of his unpublished manuscripts. This editing and research work will be an addition to the literary history of Punjab. I hope it will enhance the value of Urdu literature of Punjab.
