دو شنبہ، ۱۸؍ شعبان المعظم ۱۴۲۲ھ مطابق ۵؍ نومبر ۲۰۰۱ء کی صبح کو عربی زبان و ادب کے استاد، تاریخ اسلام کے ماہر اور ممتاز مصنف ڈاکٹر خورشید احمد فارق کوئی ۸۵ سال کی عمر میں طویل علالت کے بعد دہلی میں وفات پاگئے۔
وہ ۱۹۱۶ء میں بریلی میں پیدا ہوئے۔ فارسی و عربی کی متد اول کتابیں انھوں نے گھر پر اپنے والد ماجد سے پڑھیں۔ کالج کی تعلیم انھوں نے بریلی میں حاصل کی۔ ایم۔اے اور پی۔ایچ۔ڈی انھوں نے مسلم یونیورسٹی علی گڑھ سے کیا۔ ریسرچ کے دوران وہ شعبہ عربی میں کچھ کلاسیں بھی لیتے رہے۔ ۱۹۴۳ء کے اواخر میں وہ اینگلو عربک کالج دہلی میں لکچرر، ۱۹۵۳ء کے اواخر میں دہلی یونیورسٹی میں ریڈر مقرر ہوئے۔ اکتوبر ۱۹۵۶ء میں حکومت ہند کے ایک وظیفے پر ایک سال کے لیے وہ مصر گئے۔ وہاں دارلکتب المصریہ کے مخطوطات کے مطالعے کا انہیں اچھا موقع ملا۔ ریاض الرحمن خاں صاحب شروانی اور عبدالحلیم ندوی صاحب کو بھی اسی سال یہ وظیفہ ملا تھا۔ قاہرہ میں ان تینوں کا خوب ساتھ رہا۔ فروری ۱۹۶۹ء میں وہ دہلی یونیورسٹی میں پروفیسر اور صدر شعبہ مقرر ہوئے۔ جولائی ۱۹۸۵ء میں وہ متقاعد ہو کر علی گڑھ آگئے اور سر سید نگر میں اپنے تعمیر کردہ مکان ’’بانس کلی‘‘ میں مقیم ہوکر علمی و ادبی کاموں میں مصروف ہوگئے۔ آخر عمر میں وہ اپنے بچوں کے پاس دہلی چلے گئے تھے، وہیں ان کی وفات ہوئی۔ جامعہ ملیہ اسلامیہ کے قبرستان میں ان کی تدفین عمل میں آئی۔
ڈاکٹر فارق نے اردو، انگریزی اور عربی میں عربی اور تاریخ اسلام کے موضوعات پر متعدد کتابیں لکھیں اور کثرت سے مضامین سپرد قلم کیے جو زیادہ تر رسالہ ’’برہان‘‘ دہلی میں شائع ہوئے۔ ان کی تصانیف حسب ذیل ہیں:

Media in its various forms has become a significant part of everyday social life. It influences both how we see ourselves and the world around us to some extent. At different screens of media, images of men and women are presented in different ways and with different characteristics. Studies have been conducted at large regarding representation of gender in movies and television drama serials. This paper was meant to be an addition to this vast canvas of research through analysis of gender representation in the comedy dramas of Pakistan. According to West and Zimmerman’s theory of ‘doing gender’, gender is performed by the people in their everyday actions and interactions. Keeping in view the concept of doing gender this study analyzed roles of males and females and tried to find out how different characters maintain their gender identities in comedy dramas. Results suggested that the characters were, at many places, observed to be acting contrary to the roles associated to their genders by the society. They did or performed gender to maintain their identities.
The re-introduced liquid/semisolid matrix technology, in recent past encompasses filling of hard gelatin capsules for thixotropic system at ambient and thermosoftened system at elevated temperature. Formulations in both of the above systems may contain dissolved or dispersed drugs. In the present work thixotropic gels were prepared using a series of hydrophilic poloxamers (Pluronic/Synperonic L31, L43, L62, L64, L92) of different viscosities and composition of polyoxyethhylene and polyoxypropylenein co-polymers thickened with hydrophilic silicon dioxide (Aerosil®A200) to form gel structure. Model drugs of varying solubilities, isoniazid, metronidazole, paracetamol and mefenamic acid were dispersed in gels of above poloxamers. The gel formulations were filled into hard gelatin capsules via syringe. The rheological characteristics, dispersion stability, and FTIR of the gels with and without drugs were investigated. The gels with drugs were additionally characterized for their release pattern. In preliminary studies, twenty separate gels of poloxamers L31, L64 were thickened with concentrations 1 to 10% w/w of Aerosil® A200 to incorporate isoniazid (unsifted, 10% w/w). Different concentration of Aerosil® A200 affected dispersion stability as well as release of the drug incorporated into gels. All gels were thixotropic and shear thinning. A little change in apparent viscosity on storage upto 30 days was noted. Disperse phase sedimentation was not observed with more viscous poloxamer and with higher concentration of silicon dioxide. Higher concentration of Aerosil® A200 resulted into stronger gel structure between silicon dioxide and poloxamers and thereby, hindered release of drug from a gel. Rheograms of poloxamers, L31 and L64 confirmed their Newtonian behaviour, in contrast to the thixotropic behaviour of all gels made with Aerosil® A200 concentrations (1-10% w/w) and 10% w/w isoniazid. Therefore, ii in-vitro release of highly water soluble drug, isoniazid could be controlled by poloxamer/A200 thixotropic gel system which depended upon concentration of Aerosil® A200, viscosity of poloxamer and the aqueous solubility of drug. In the further work, the effect of selected concentration of Aerosil® A200 (8% w/w) and five liquid poloxamers of different viscosities on release of drugs with characterized particle size (180-250 μm) and of different from semi solid matrix/ thixotropic gel filled into hard gelatin capsules was tested by in-vitro dissolution test. The drugs with different solublities used in this study were isoniazid, metronidazole, paracetamol and mefenamic acid. The interaction of drug in gel formulations was also determined by Fourier transform infrared (FTIR) spectroscopy. The release of drugs from different formulations was related to their aqueous solubility, viscosity of poloxamers, and poloxamer’s polyoxyethylene and polyoxypropylene proportions. In most of the formulations drug remains dispersed over a period of one month depending upon the viscosity of gels. Most of the gels showed little change in apparent viscosity on storage. The apparent viscosity for each gel was found to be dependent on the viscosity of poloxamers from which the gel was prepared. Like in preliminary work, rheograms of five pure poloxamers showed Newtonian behaviour whereas each gel exhibited thixotropic and shear thinning. In-vitro dissolution data of drugs from their respective stable gels followed first order kinetics. No chemical interaction or incompatibilities between drugs and polymers were noted by FTIR. Long term stability studies at International conference on harmonization (ICH) recommended conditions of temperature/relative humidity (30°C/65% RH) over one year revealed that almost all the gels retained their rheological, dispersion stability, release profile and chemical integrity. Thus, the hydrophilic semisolid matrix (gels) made by mixing poloxamer and Aerosil® (A200) was suitable for filling into hard gelatin capsules because of their rheological characteristics. The release of drugs with different solubilities could be modified by using iii poloxamers of different viscosity. Overall present research study demonstrates the effect of silicon dioxide on the microstructure of the gel prepared with various poloxamers which is evident from the rheological studies, FTIR and release pattern of the drugs.
