مولانا حافظ محمدیوسف کوکن مدراسی

افضل العلماء حافظ محمد یوسف کوکن مرحوم
تار کے ذریعہ یہ افسوسناک خبر ملی کہ دارالمصنفین کی انتظامیہ کے رکن اور مدراس یونی ورسٹی کے سابق صدر شعبہ عربی و فارسی، افضل العلماء حافظ محمد یوسف کو کن کا انتقال ۶؍ اکتوبر کو مدراس میں ان کے گھر پر ہوگیا، اِنا ﷲ واِنا الیہِ راجعُون۔
انہوں نے سرزمین مدارس میں مشرقی و دینی علوم کی قابل قدر خدمت جس خاموشی، محنت اور انہماک سے انجام دی اس کی وجہ سے برسوں ان کی کمی محسوس کی جائے گی۔ وہ ۴؍ نومبر ۱۹۱۵؁ء مدراس سے تقریباً ۹۵ میل دور ایک مردم خیز قصبہ مینمبور میں پیدا ہوئے یہ قصبہ مشہور قلعہ جبنحی سے متصل ہے، اس مضبوط قلعہ کو مسلمان فاتحین نے کئی بار اپنے قبضہ میں لیا، آخری بار نواب سعادت اﷲ خاں نے ۱۱۲۵؁ھ میں اس پر قبضہ کیا، چونکہ ان کا تعلق نوائط سے تھا اس لیے اکثراہل نوائط وہاں جاکر آباد ہوئے، مینمبور قصبہ کی ساری آبادی نائط مسلمانوں کی ہے جو اپنے حسب نسب، عزوشرف، دینی اور دنیوی وجاہت اور اپنے بعض مخصوص رسم و رواج کی وجہ سے جنوبی ہند میں امتیازی شان رکھتے ہیں، یہ لوگ شافعی المسلک ہوتے ہیں لیکن مینمبور کے نوائط عام طور سے حنفی ہیں، کوکن خاندان بھی حنفی المسلک ہے، گویہ خاندان عرصہ سے مدراس میں آباد ہے لیکن اس کی مادری زبان اردو ہے اور نصف صدی قبل اس کی علمی زبان فارسی تھی۔
کوکن مرحوم نے جامعہ دارالسلام عمر آباد میں تعلیم حاصل کی ، بعد میں انہوں نے گورنمنٹ مسلم کالج مدراس سے افضل العلماء اور منشی فاضل کی سند حاصل کی، دارالسلام عمرآباد کے مقاصد میں یہ بات بھی تھی کہ جامعہ کے طلبہ میں عربی اور فارسی کے ساتھ اردو کا اعلیٰ ذوق اور تصنیف وتالیف کا سلیقہ و ملکہ...

Association of COVID-19 with obesity Association of COVID-19 with obesity

COVID-19 is a disease that cause respiratory illness due to novel corona virus. It was reported to WHO on December 31,2019 for the first time. The outbreak of this disease started from Wuhan city, China. Now COVID-19 pandemic is spreading worldwide mostly in Europe and North America, these regions have high prevalence of obesity. In the pathogenesis of COVID-19 disease, obesity assumes a significant job. Theinsusceptible framework, which is official in the pathogenesis of COVID19, assumes asignificant job in weight instigated fat tissue aggravation. In the fat tissue the irritationbrings about metabolic brokenness conceivably prompting dyslipidemia, type 2diabetes mellitus, insulin obstruction, hypertension and cardiovascular sickness. Obesity has been expanded the vulnerability to contaminations. In this pandemic, a large number of obese individual with Covid-19 are reported. Infection rate in obese is greater due to poor immunity, comorbidity and inadequate nutritional needs. Statistical analysis showed that about 41.7% patients reported in New York city were obese. Whereas 40% obese have been reported in United State of America with Covid-19. A report from UK indicated that 38% obese were admitted in ICU with Covid-19. According to Chinese researchers, obese individuals are 3-timesmore prone toward the development of Covid-19. So recent analysis indicated that obesity is the major risk factor of Covid-19. In COVID-19, overweight and obese patients have high danger of metabolic difficultiesand eternal infections that stoutness works. More nutrition care is required for such patients. As nutrition is a key factor for keeping up human wellbeing, for example, denseimpervious framework and satisfactory admission of supplements and dietaryenhancements. Tolerant with COVID-19 create contamination from slight to seriousindications bound to the dietary status. Consequently, assessing wholesome status ofindividuals with contamination turns out to be increasingly significant. Through dietaryhelp, we can bring down the danger of oxidative pressure, infection contamination andexpands invulnerability framework among obese people especially.

Synthesis, Characterization and Fabrication of Metal Organic Framework Composites for Adsorption and Electrochemical Applications

Four metal organic frameworks [Zn(3-bpmh)(1,4-bdc)]n, [Cd(3-bpmh)(1,4-bdc)]n [C8H10CdO7]n.4H2O and C15H17N2NiO8 (Ni-BTC) were synthesized and characterized. N-doped nanostructured porous carbon materials coded as PCN920 and PCN900 were obtained through the thermal treatment of two frameworks [Zn(3-bpmh)(1,4-bdc)]n and [Cd(3-bpmh)(1,4-bdc)]n, respectively under argon gas environment, while the third compound [C8H10CdO7]n.4H2O had produced porous carbon material (PC900) through the same heating process as described earlier. The thermal evaporation of Zn metal yielded impressively high surface area carbon (PCN920), which is found to be 1171 m2g-1, while Cd metal elimination from [Cd(3-bpmh)(1,4-bdc)]n and [C8H10CdO7]n.4H2O had generated relatively low surface area carbon i.e. 407 m2g -1 for PCN900 and 877 m2g -1 for PC900. The derived carbon materials PCN920, PCN900 and PC900 had been utilized for the synthesis of bimetallic composites with 10% Pt and 5% second metal (Ni, Cu, Er) through polyol reduction procedure. The bimetallic composites synthesized from PCN920 are coded as Pt-Ni@PCN920, Pt-Cu@PCN920 and Pt-Er@PCN920, while that were prepared from PCN900 are coded as Pt-Er@PCN900 and Pt-Ni@PCN900 and Pt-Cu@PCN900. The PC900 used as support to prepare composites are Pt-Er@PC900 and Pt-Ni@PC900 and Pt-Cu@PC900. The layered cadmium framework [C8H10CdO7]n.4H2O was synthesized in crystal form and characterized through single crystal X-ray analysis. The infrared spectroscopy (IR), UV-Vis spectroscopy and terahertz time-domain spectroscopy (THz TDS) were performed for cadmium metal organic framework. The computational investigations of the framework were performed at B3LYP/LANL2DZ level in gas phase to support our experimental results. The terahertz time domain spectroscopy of [C8H10CdO7]n.4H2O was performed and its refractive index along with absorption coefficient in 0.2-1.3 THz range x were calculated. The Nonlinear optical properties analysis reveals that the first static hyperpolarizability of [C8H10CdO7]n.4H2O is 38 times greater than that of urea. All the composites have been characterized through PXRD, FTIR, RAMAN, BET, XPS, ICP, CHNS/O, EDX, SEM and TEM. The composites Pt-Ni@PCN920, Pt-Cu@PCN920, Pt-Er@PCN920, Pt-Er@PCN900, Pt-Ni@PCN900 and Pt-Cu@PCN900 were analyzed for three important electrocatalytic reactions oxygen evolution (OER), hydrogen evolution (HER) and oxygen reduction reactions (ORR), while Pt-Er@PC900, Pt-Ni@PC900 and Pt-Ni@PC900 were used as electrocatalysts to perform HER and ORR. The performance of Pt-Ni@PCN920 is found to be better than Pt-Er@PCN920 and Pt-Cu@PCN920 having the same substrate PCN920. Secondly, Pt-Er@PCN900 showed excellent performance for HER, OER and ORR than Pt-Ni@PCN900 and Pt-Cu@PCN900. The durability and stability of Pt-Er@PCN900 was marvelous. Thirdly, the performance of Pt-Er@PC900 was superb than Pt-Ni@PC900 and Pt-Cu@PC900. The Nickel metal organic framework, graphene oxide (GO) and their composites Ni-BTC@GO(1%), Ni-BTC@GO(2%), Ni-BTC@GO(3%), Ni-BTC@GO(4%) and Ni-BTC@GO(8%) were synthesized, characterized and used as adsorbents for denitrogenation of synthesized model fuel. The porosity of the composite was enhanced by adding GO as compared to pristine Ni-MOF. The composite material with enhanced porosity and high surface area was used as adsorbent to remove indole, pyridine and quinoline from synthesized model fuel. The adsorption results showed profound increase in the adsorption capacity of the Ni-MOF@GO composite as compared to the pristine MOF. The composites also showed good regenerative ability and reusability.
