مولانامسعود عالم ندوی

مولانا مسعود عالم ندوی
ابھی حضرت الاستاذ رحمہ اﷲ کا غم نہ بھولا تھا کہ ندوہ کے ایک نامور فرزند مولانا مسعود عالم ندوی کا ماتم گسار ہونا پڑا، مرحوم نے چند گھنٹوں کی علالت کے بعد ۱۶؍ مارچ کو کراچی میں وفات پائی، وہ ندوہ کے اس دور کی بہترین پیداوار تھے۔ اﷲ تعالیٰ نے ان کو بڑی صلاحیتیں عطا فرمائی تھیں، عربی کے ممتاز ادیب و انشاء پر داز تھے انگریزی سے بقدر ضرورت واقفیت اور اردو کا ستھرا مذاق رکھتے تھے ان کے مضامین مصر و شام کے اخبارت و رسائل میں شائع ہوتے تھے، اور اہل زبان ادیبوں سے خراج تحسین حاصل کرتے تھے، ابتداء میں ندوہ میں ادب کے مدرس تھے، اسی زبان میں انھوں نے حضرت الاستاذؒ کی نگرانی میں عربی کا ایک رسالہ الضیاء نکالا تھا، جو چند سال نکلنے کے بعد بند ہوگیا، اس کے بعد اورنٹیل پبلک لائبریری پٹنہ میں فہرست نگار ہوگئے اور انگریزی میں عربی کے متفرق محظوطات کی فہرست کی ایک جلد مرتب کی جو چھپ کر شائع ہوگئی ہے۔
ان میں مسلمانوں کی دینی اصلاح کا جذبہ شروع سے تھا اور وہ وقتاً فوقتاً اصلاحی مضامین لکھتے رہتے تھے اس سلسلے میں شیخ محمد بن عبدولوہاب نجدی پر معارف میں ایک طویل مضمون لکھا تھا جو بعد میں ترمیم و اضافہ کے بعد کتابی صورت میں شائع ہوا، اسی جذبہ کے ماتحت وہ جماعت اسلامی میں شامل ہوگئے اور پاکستان ہجرت کر گئے تھے اس کے وہ بڑے سرگرم کارکن تھے، ان کی شرکت سے اس تحریک کو بڑا فائدہ پہنچا اس کو مضامین کے ذریعہ اسلامی ملکوں میں روشناس کرایا اس کی تبلیغ و اشاعت کے لیے عراق و شام کا سفر کیا اس کی متعدد اہم کتابوں کا عربی میں ترجمہ کیا ابھی حال میں ہندوستان میں اسلامی دعوت کی تاریخ اور...

Muslim-Christian Dialogue from Pakistani Perspective: Evaluation of the Contribution of Christian Study Center

The twentieth century is considered as the most notable era for interfaith dialogue and other interreligious activities among the followers of different faiths across the globe. A number of interfaith activities were launched to bring closer, especially, the adherents of the Abrahamic faiths: Jews, Christians and Muslims. Many Christian institutes and organizations are actively involved in such activities. We cannot ignore the role of Christian Study Centers situated across the globe, which are rendering considerable services in the field of interfaith dialogue. One of them is the Christian Study Center Rawalpindi (CSC), Pakistan, which is the focal subject of this research paper. The CSC has a long journey in the course of interfaith dialogue and harmony, as it was its objective since its commencement. The CSC was established in 1967 as an extension of HMI (Henry Martyn Institute, Hyderabad India) to promote interfaith dialogue, harmony and good relationship among the followers of different faiths in Pakistan. It is conceded; the Christian Study Center Rawalpindi has provided great services and contributed a lot to interfaith dialogue, harmony and peace in Pakistan. In this study the efforts were made to evaluate the 50 years dialogical activities of the Christian Study Center (CSC), Rawalpindi.

Modeling of High Strength and Wear Resistance Alumi

Modeling of high strength and wear resistance aluminum alloy based casting of composite material developed via conventional foundry method which is one of the most economical versatile and active research area and so for has not been thoroughly investigated. Due to complex nature of the composite materials and their related problems such as the nonlinear relationship between composition, processing parameters, heat treatment with the strength and abrasive wear, resistance can more efficiently be modeled by artificial neural networks. The artificial neural networks modeling requires sufficient data concerned with chemical composition , processing parameters and the resulting mechanical properties which were not available for such type of modeling. Therefore, a wide range of experimental work was conducted for the development of aluminum composites using conventional foundry method. Alloy containing Cu-Mg- Zn as matrix and reinforced with 1- 15 % Al 2 O 3 particles were prepared using stir casting method. The molten alloys composites were cast in metal mold. More than eighty standard samples were prepared for tensile tests and sixty samples were given solution treatment at 580 0 C for 1⁄2 hour and tempered at 120 0 C for 24 hours. Various characterization techniques apparatus such as X-ray Spectrometer, Scanning Electron Microscope, Optical Metallurgical Microscope, Universal Tensile Testing Machine, Vickers Hardness and Abrasive Wear Testing Machine were used to investigate the chemical composition, microstructural features, density, tensile strength, ductility (elongation), hardness and abrasive wear resistance. xixThese investigations including the material development and characterization were used for data generations as needed for modeling of high strength and abrasive wear résistance aluminum cast composites. For modeling purpose a multilayer perceptron (MLP) feedforward was developed and back propagation learning algorithm was used for training, testing and validation of the model. The modeling results shows that an architecture of 14 inputs with 9 hidden neurons and 4 outputs which include the tensile strength, elongation, hardness and abrasive wear resistance gives reasonably accurate results with an error within the range of 2-7 % in training, testing and validation. The modeling results shows that an alloy contents 2-3 % Cu, 2-3 % Mg, 3-5 % Zn reinforced with 10 % Al 2 O 3 can successfully be developed for highest strength (297 MPa) and highest abrasive wear résistance (0.4 gm weight loss /15 minutes using stir casting method. The modeling results also suggest that it is possible to develop the highest strength 466 MPa tensile strength and highest abrasive wear resistance aluminum alloy based casting composite materials having the matrix composition of 6 % Si, 2 % Mg with 3 % Zn reinforced with 2-5 % Al 2 O 3 particles.
