پروفیسر باور

پروفیسر باور
پچھلے مارچ میں جرمنی کے ہالے یونیورسٹی کے علوم مشرقیہ کے پروفیسر باور کا انتقال ہوگیا، وہ لسانیات کے ماہر تھے، وہ یورپ کی تقریباً جملہ زبانوں کے جاننے کے علاوہ ساری سامی زبانوں سے واقف تھے اور تورانی زبانوں خصوصاً چینی زبان میں خاص مہارت رکھتے تھے۔ اس حیرت انگیز وسیع لسانیاتی واقفیت کے سبب سے وہ راس شمرہ کی کھدائیوں میں بعض نئے خطوں کے کتبوں کے برآمد ہونے پر ان کو حل کرسکے، ماسوف علیہ کو امام غزالی کی احیاء العلوم سے خاص دلچسپی تھی، اس کے متفرق ابواب کے ترجمے اکثر شائع کرایا کرتے تھے، اسلامی علم مرایا و مناظر پر بھی بعض اچھے مضمون لکھے تھے، انسائیکلوپیڈیا آف اسلام کے شریک ناشر بھی تھے اور فلک، حاء، حفص الفرد، وغیرہ عنوانوں پر اس میں مقالے لکھے تھے، ’’حرف تہجی کی ابتداء‘‘ پر ان کی ایک جرمن تالیف اس وقت مطبع میں ہے۔ (سید سلیمان ندوی، جولائی ۱۹۳۷ء)

 

سیرت طیبہ ﷺ کی روشنی میں تصور فلاح و بہبود

Islam is the religion of welfare. It emphasizes on accomplishing the rights of human beings concurrently the rights of Allah. Similarly, the government and the member of society jolted regarding this collectively. And everyone is stimulated concerning his responsibilities and adjudges the followers just like one body. Islamic community is just like a cooperative society. It is a duty of everybody to assist the deprived not only financially but also ethically. Until, to meet affably is declared charity. The leader of Islamic state is the responsible for the welfare of everybody. Rather he is bound to feed every being. That is why Haḍrat ʻUmar said that he is liable in the Day of Judgment if a dog is died due to starvation in his regime. In the research paper, the concept of welfare has been manifested in the light of Sīrat-al-Nabī. The method adopted for the research is qualitative as well as descriptive. The Holy prophet urged the believers of Islam on mutual assistance in adverse times. In disaster situations, the responsibilities of every Muslim increase and he should devote his intention tooth, nail and body to rescue.

Some Flows of Non-Newtonian Fluids

This work presents new results regarding the behavior of some non-Newtonian fluids into different circumstances. Chapter 1 presents the preliminary concepts regarding Newtonian and non-Newtonian fluids, the constitutive equations and the equations of motion and integral transforms. New exact solutions for the velocity field and the shear stress corresponding to some flows of ordinary and generalized Maxwell fluids, ordinary second grade and Oldroyd-B fluids have been established. In chapter 2, by means of the Laplace transform, we have established new exact solutions corresponding to Stokes’ type flows for ordinary Maxwell fluids with slip boundary conditions. We obtained the velocity field corresponding to both cases with slip and non-slip conditions, for Maxwell and viscous Newtonian fluids . Also, the exact and approximate solutions are compared and a good agreement is found. In chapter 3, some new exact analytical solutions for Stokes’ first problem of Maxwell fluid with fractional derivative approach are established. The obtained so- lutions for the velocity field and shear stress, written in terms of generalized G − Lorenzo − Hartleyf unctions, are presented as a sum of the similar Newtonian solu- tions and the corresponding non-Newtonian contributions. Chapter 4 contains exact solutions for the helical flow of a second grade fluid, between two infinite coaxial circular cylinders. Solutions are presented in series form, in terms of Bessel functions and they are written as a sum of large-time and transient solutions. Lastly, chapter 5 is devoted to the study of unsteady flow of an Oldroyd-B fluid through the infinite circular cylinder on which a sinusoidal azimuthal tension is given. Solutions, obtained by means of the Hankel and Laplace transforms, are written as a sum of large-time and transient solutions. The corresponding solutions for Maxwell and Newtonian fluids are obtained as limiting cases.
