حاجی رشید الدین

حاجی رشیدالدین
گذشتہ مہینہ اعظم گڑھ کی ایک پرانی یادگار حاجی رشید الدین صاحب نے بھی وفات پائی، مرحوم ترجمان القرآن مولانا حمیدالدین فراہیؒ کے سگے اور مولانا شبلی مرحوم کے ماموں زاد بھائی تھے، دارالمصنفین سے ان کا تعلق بہت قدیم اور مخلصانہ تھا، اس کی مجلس انتظامیہ کے رکن بھی تھے، مولانا حمید الدین صاحب مرحوم کے بعد مدرستہ الاصلاح سرائے میر کو ان ہی نے سنبھالا تھا، اور عرصہ تک اس کے ناظم رہے، ادھر چند سال سے ضعف پیری کی وجہ سے اس خدمت سے سبکدوش ہوگئے تھے، طبعاً بڑے نیک سیرت، پاک دل اور مرنجاں مرنج تھے، مولانا شبلی کے اعزہ میں سب سے زیادہ سن رسیدہ اب وہی رہ گئے تھے، نوے سال کے قریب عمر تھی، ادھر کئی سال سے بالکل معذور ہوگئے تھے، ہوش و حواس نے بھی جواب دیدیا تھا، صرف رشتۂ حیات باقی تھا، افسوس کہ وہ بھی منقطع ہوگیا، اﷲ تعالیٰ مرحوم کو اپنی رحمتِ کاملہ سے نوازے۔
(شاہ معین الدین ندوی، نومبر ۱۹۵۹ء)

أعلام النثر العربي في شبه القارة الهندية

This research article is based on contribution of sub-continent’s outstanding Islamic personalities and their leading role which they have played in establishing and strengthening linguistically, literarily and cultural links between Arabs and non-Arabs Various Arabic cultured institutions of higher learning under the personal guidance and scholarly interest Sultans setups which produced a good number of writers, Islamic thinkers, commentators of the holy Quran, scholars of hadith and understanding of language and literature. Moreover, their nobal work can be composed to any great arab scholar. The work, personalities and their extra ordinary Arabic books including literature in sub-continent is key part of this research. These personalities are Ameer Ali, Mohammad Aizaz Ali, Allama Syed Abu-Alhasan Ali Al-Nadvi, Shah Waliullah Dehlvi, Mahmmod Bin Muhammad Al Janfori, Shaikh Nizamuddin Lakhnavi, Al-Hindi Saffiduddin and Hazarat Shah Ismail Shaeed Brailvi.

Study of Gamma Ray Detector Efficiencies and Integral Parameters Using Stochastic Simulations and Analytical Techniques

Shakeel ur Rehman, PhD, Department of Physics & Applied Mathematics, PIEAS, July 2010. “Study of gamma-ray detector efficiencies and integral parameters using stochastic simulations and analytical techniques”; Supervisor: Dr. Nasir M. Mirza; Co-Supervisor: Dr. Sikander M. Mirza; Department of Physics & Applied Mathematics, PIEAS, Nilore 45650, Islamabad. In this work a novel primary-interaction based methodology has been developed for Monte Carlo based calculations of the detector efficiency which accelerate the computations and yields converged results with much shorter computer time. The proposed methodology has been first implemented in a MATLAB based computer program PIMC and later implemented in the state-of-the-art GEANT4 Monte Carlo simulation toolkit. The methodology has been used for point isotropic sources and thin disk sources at axial locations as well as off-axial locations with respect to the detector axis, excellent agreement has been found between the predictions of the PIMC code with the corresponding results obtained by using hybrid Monte Carlo as well as by analytical techniques and experimental measurements over a wide range of γ-ray energy values. Using the PIMC program, the energy dependent detector efficiency has been found to approach an asymptotic profile by increasing either thickness or diameter of scintillator while keeping the other fixed. The variation of energy dependent total efficiency of a 3" × 3" NaI(Tl) scintillator with axial distance has been studied using the PIMC code. About two orders of magnitude change in detector efficiency has been observed for zero to 50 cm variation in the axial distance. For small values of axial separation, a similar large variation has also been observed in total xviiefficiency for 137 Cs as well as for 60 Co sources by increasing the axial-off set from zero to 50 cm. The results for disk sources show a gradual decreasing trend in the total efficiency as disk source radius increases. For coaxial thin disk sources, the total detection efficiency has been found to approach a corresponding maximum value as length is increased in 1–20 cm range for various values of radii of disk sources and γ-ray energy while keeping the diameter of the detector fixed at 3” (7.62 cm). A similar behavior is observed when the radius of the detector is increased from 1–20 cm while keeping the length of detector fixed at 3” (7.62 cm), for various values of radii of disk sources and γ-ray energy. Then Monte Carlo simulations were carried out for the determination of photo peak- to-total ratio using the GEANT4 based detector model for various gamma ray energies and detector materials. The effect of variation of length and radius of the detector, while keeping the other fixed, was studied for various gamma ray energies. Mathematical curves for peak- to-total ratio were derived for various detector materials.
