شیخ ظہور الحسن
افسوس ہے کہ شیخ ظہورالحسن صاحب سابق ریوینیو سکریٹری حکومت اتر پردیش نے کراچی میں انتقال کیا، وہ اپنے محکمہ کے ماہر اور اس صوبے کے لائق ترین عہدہ داروں میں تھے، حکومت میں ان کا بڑا وقار تھا، عملاً بڑے مذہبی اور دیندار تھے، مذہبی مطالعہ وسیع تھا، دینی کاموں سے بڑی دلچسپی تھی، ترک وطن سے پہلے دارالمصنفین کی مجلس انتظامیہ کے رکن تھے، کئی سال ہوئے ریٹائرڈ ہوچکے تھے، ان کے لڑکے پاکستان میں بڑے عہدوں پر تھے، لیکن وہ خود ہندوستان ہی میں مقیم رہے، ۱۹۶۵ء کی جنگ سے کچھ پہلے لڑکوں سے ملنے کراچی گئے تھے، اسی دوران میں جنگ چھڑگئی، اس لیے لڑکوں کے اصرار سے وہاں مستقل قیام اختیار کرلیا، اور وہیں قلبی دورے میں وفات پائی، مسلمان عہدہ داروں میں ایسے لائق اور دیندار کم ہوتے ہیں، اﷲ تعالیٰ اس مرد مومن کی مغفرت فرمائے۔ (شاہ معین الدین ندوی، جنوری ۱۹۷۲ء)
Sindh remains a center of great Islamic scholar in early ages till now, scholars of Sindh served in all the fields of Islamic studies. Among Islamic Scholars of Sindh who have left unmatchable repute Sayyed Badi‘ud-Din Shah alR┐shidi, is one of them. He was at home in Quran and its sciences, Hadith and its science, Fiqah and its science. He was author of many books among them was Badi‘ul Taf┐sir, Badi‘ul Taf┐sir (اافتلرس دبعی (currently Contains 11th volumes including excurses (دقمہم (this tafsir adheres to the following sequence: (1) Tafsir of Quran by the Sunnah. (2) Tafsir of Quran by Language. (3) Tafsir of Quran by Opinion. Badi‘ul Tafasir is worthy to get the award of best Sindhi tafsir of this time. In this manuscript it is proved that Badi‘ul Tafasir is best collection of Religious commandments which has been described in detail according to jurisprudential Viewpoints and qualities.
The primary objective of this thesis is to investigate the flow of various physiological and biological fluids in a small diameter permeable tube under different flow conditions as an application to the flow in the renal tubules of kidney. The problem of creeping motion of an incompressible fluid in a small diameter permeable tube is being presented. The fluid absorption at the tube wall is taken as a function of wall permeability and the pressure gradient across the tube wall. Hydro dynamical flow equations and the appropriate boundary conditions for the flow of Newtonian fluid and some non-Newtonian fluids in a permeable tube are developed. Assuming the tube radius to be very small as compared to its length, exact/approximate solutions of these equations are obtained. Expressions describing variations in the axial volumetric flow rate, mean pressure difference, wall leakage flux, wall shear stress and the fractional re-absorption are derived. Graphs are sketched in order to describe effects of various parameters of interest on different flow variables and implications of the results are discussed briefly. The obtained solutions are applied to the flow problem in the renal proximal tubule of kidneys and theoretical values of the wall permeability parameter, inlet pressure, mean pressure drop and fractional re-absorption in the proximal tubule are obtained. It is found that along with other quantities of interest, the mean pressure drop and the fractional reabsorption in proximal tubule have significant variations as the underlying fluid model and/or flow conditions are varied. For specific values of parameters, the expression of the axial flow rate reveals that volumetric flow rate in the renal tubule decreases exponentially as a function of the axial distance. This is a biologically significant, well accepted and frequently reported result in the literature. When certain parameters are set equal to zero, the derived solutions coincide well with the existing solutions for creeping flow of a linearly viscous (Newtonian) fluid in a small diameter permeable tube.
