In the present study, Alishewanella sp. CBL-2 was characterized on the basis of biochemical and 16S rRNA sequencing. The bacterium was found to decolorize 83% Sumifex Tourqi blue within a period of 6 days at 37C and pH 7. The predominant form of the enzyme was found to be extracellular (78%) as compared to intracellular (16%). The breakdown of azo bond was confirmed through thin layer chromatography (TLC) analysis as new bands and peaks were observed in chromatograms of extracted metabolites of decolorized samples. Growth of beneficial microbial fauna in the presence of bacterial decolorized wastewater indicates that this wastewater is safe for the survival of microorganisms. High bioremediation potential makes Alishewanella sp. CBL-2 an impending foundation for green chemistry to remove azo dyes from industrial wastewater.In the present study, Alishewanella sp.

مفتی محمد عبداﷲ ٹونکی

مفتی محمد عبداﷲ صاحب ٹونکی

اخبارات سے یہ خبر معلوم ہوچکی ہوگی کہ جناب مولانا مفتی محمد عبداﷲ صاحب ٹونکی نے ۷؍ نومبر ۱۹۲۰؁ء کو بعارضۂ فالج بھوپال میں انتقال کیا، مفتی صاحب مرحوم عربی درسگاہوں کی قدیم تعلیم کے بہترین نمونہ تھے، ہندوستان کے مشاہیر علماء میں ان کا شمار تھا، وہ ادب میں مولانا فیض الحسن صاحب اور دینیات میں مولانا احمد علی صاحب محدث کے شاگرد تھے، مولانا فیض الحسن صاحب کے انتقال کے بعد اورینٹل کالج لاہور کی پروفیسری کی جگہ ان کو ملی اور ان کی عمر کا بڑا حصہ اسی درسگاہ میں گزرا، اخیر زمانہ میں وہ دارالعلوم ندوہ کے مدرس مقرر ہوئے تھے اور اس کے بعد مدرسۂ عالیہ کلکتہ کے صدر مدرس ہوئے اور یہیں سے بیمار ہوکر اپنے صاحبزادہ جناب مفتی انوارالحق صاحب ایم، اے ناظم و مشیر تعلیمات بھوپال کے پاس گئے تھے جہاں انہوں نے وفات پائی، غالباً وفات کے وقت مفتی صاحب مرحوم کی عمر ستر (۷۰) کے قریب ہوگی، تعلیمی خدمات کے علاوہ مفتی صاحب کا بڑا کارنامہ انجمن مستشار العلماء لاہور ہے، جو ایک قسم کا دارالافتاء ہے۔ مرحوم نے بعض عربی کی درسی کتابوں پر حواشی بھی لکھے تھے۔ ان کی وفات سے علماء کی صف میں ایک ایسی جگہ خالی ہے جس کے بھرنے کی اب آئندہ امید نہیں۔

تقسيم العقوبات المادية بين الشريعة الإسلامية والقانون الوضعي

Allah (S.W.T) has given solutions to all worldly problems in Islamic Sharīʿah; this is why many crimes are punished through monetary laws. Whatever money is collected through these monetary punishments is deposited in the government’s treasury. This monetary punishment is called gharāmah. According to Islamic jurisprudence penalty plus punishment might be reduced if the accused is a juvenile or mentally unstable or drunk or has committed the crime by mistake, or was asleep or not fully awake or not in his full senses. Furthermore, some criminals are acquitted just after acceptance and repentance. This paper attempts to study this topic.

The study of Mediating Effect of Perceived Value Between Brand Equity and Customer Repurchase Intentions of Mobile Phone Users

This study is conducted to analyze that perceived value of brand has an impact on the consumer purchasing and revisiting intentions. The study explores the influences of brand consciousness, brand experience, brand loyalty, brand awareness, and brand association on brand perceived value due to these this influences on revisiting intentions. The sample size of 250 mobile phone users has been taken in this research. The non- probability convenience sampling is used and target respondents are the cellular users living in Islamabad and Rawalpindi. Close-ended structured questionnaire is used for data collection and correlation and regression used for data analysis. Six hypotheses were tested in the study. Survey was conducted among mobile phone users in Rawalpindi and Islamabad. In overall perspective and in mobile phone sector, there is a high correlation between the independent and dependent variables. There is strong positive correlation between perceived value (mediating variable) and customer repurchase intentions (dependent variable) brand consciousness, brand experience, brand awareness, brand loyalty, and brand associations (independent variables) but with little distinction. For both academics and practitioners, the discoveries of this study hold significant implications. This research escorts the policy makers and academics about the main predictors of consumer's attitude towards repurchase in mobile phones industry.
