مولانا حکیم محمد عرفان الحسینی

مولانا حکیم محمد عرفان الحسینی
افسوس کہ کلکتہ کی معروف ، متحرک اور مرنجاں مرنج شخصیت یعنی مولانا حکیم عرفان الحسینی گذشتہ اپریل میں دنیا کی اس بزم فانی سے رخصت ہوگئے، انا ﷲ و انا الیہ راجعون۔ وہ کلکتہ کے مشہور اور نہایت قابل احترام عالم، مفسر قرآن حکیم محمد زماں حسینی کے صاحبزادے تھے، قدیم تہذیب اور اسلاف کی دینی و علمی روایتوں کی امانت ان کو ورثہ میں ملی اور انہوں نے اس کو نبھایا بھی بڑی خوبی سے، اپنے عظیم والد کے نقش قدم پر انہوں نے کلکتہ بلکہ پورے بنگال میں دیوبند، ندوہ، امارت شرعیہ جیسے اداروں کی نمائندگی بڑے اخلاص و استقامت سے کی، وہ ندوہ کی مجلس انتظامی کے اہم رکن رہے، مسلم پرسنل لا بورڈ میں بھی ان کی موجودگی اپنا احساس دلاتی، دارالمصنفین اور معارف سے تعلق خاندانی رشتوں کی طرح استوار و پائدار رہا، کلکتہ کی مصروف ترین ز ندگی میں وہ تحریر کے لیے وقت نکال لیتے ، روزانہ آزاد ہند میں ان کا تفسیری اور مذہبی کالم بڑی پابندی سے آتا اور قارئین اس کے منتظر رہتے، ہم نے ان کو اس وقت دیکھا جب وہ بڑے صحت مند اور چاق و چوبند تھے، لیکن ادھر کئی برسوں سے عالم اس کے برعکس نظر آیا، آگ کے خاک ہونے کا منظر پرانا ہے لیکن ابتدا و انتہا کے فاصلے جب سمٹتے ہیں تو یہی منظر حیرانی کا سبب بن جاتا ہے، کلکتہ کے قاسمی دواخانہ کی رونق عرفان صاحب کے دم سے تھی، جس کی شکل میں مذہب، علم، ادب ، شعر، حکمت اور کسی حدتک صحافت و سیاست کے سات رنگوں نے کلکتہ کے آسمان پر ایک قوس و قزح بکھیر دی تھی، مرحوم نے ان رنگوں کو پھیکا نہیں ہونے دیا، محبت کی گرمی اور گفتار کی گلفشانی، بھولنے کی چیز نہیں، اﷲ...

Association of Serum Ferritin with Risk of Anemia in Non-Diabetic Adolescents with Family History of Type 2 Diabetes Mellitus

Background: Controversy occurs in the relationship between serum ferritin levels, insulin resistance and risk of developing anemia in adolescents with family history of diabetes. Aims & Objectives: This study was designed to find out the association between serum ferritin levels with risk of developing anemia in non-diabetic adolescents with family history of type 2 diabetes mellitus (T2DM). Materials & Methods: A descriptive cross-sectional was conducted in a local medical institute of Lahore. Study included 50 non-diabetic, non-obese male / female adolescent with family history of type 2 diabetes mellitus and 50 healthy male/female non-obese adolescents without family history of T2DM considered as controls. Level of serum ferritin and serum insulin was estimated by Enzyme Linked Immunosorbent Assay. Blood glucose was estimated by auto-analyzer. Insulin resistance was calculated by HOMA-IR index and beta cell function was assessed by HOMA- beta index. Results: Levels of fasting blood sugar, insulin resistance were found to be increased with decreased level of serum ferritin and decrease beta cell function in both male as well as female cases as compared to controls. Negative correlation was found between serum ferritin and insulin resistance while a positive correlation was found between serum ferritin and beta cell function. Conclusions: Low level of serum ferritin is associated with reduced beta cell function and increased insulin resistance. This may increase the risk of developing iron deficiency anemia that can affect both immune system as well as increase susceptibility to infections.

Atmospheric Dispersion and Consequence Modeling of Radiological Emergencies

The Medium Term Development Frame Work (MTDF) 2005-10 by Planning Commission Government of Pakistan states the policy for power sector in which it puts a greater emphasis on nuclear power resources by increasing its share from currently 425 MW to 8800MW by 2030. With the increase of nuclear share in the overall national energy mix, a corresponding environmental impact and nuclear safety analysis are equally important. These are usually taken care of by Primary Safety Analysis Report (PSAR) of a proposed nuclear power plant. The PSAR of any proposed nuclear power plant involves the assessment of a hypothetical accidental release of radionuclides in the atmosphere as set forth by US-NRC and PNRA such as those given as criteria for preparation and evaluation of radiological emergency plans and preparedness (10CFR100, PAK/910). Modeling atmospheric dispersion (both transport and diffusion) is the first step of such assessments. The objective of this work is to determine a more precise modeling methodology that can better predict the radiological consequences in terms of radionuclide concentration and doses compared to Gaussian dispersion approach that is based on assumptions such as uniform turbulence, flat topography and non-variant wind speed with time and space. The research goal was achieved by developing two broad strategies on the basis of Lagrangian approach. The first strategy is an effort to provide a simple answer to the complex problem. This methodology makes use of empirical parameterization of meteorology which serves as input for dispersion calculations by Lagrangian Stochastic Particle Model (LSPM). But the beauty of approach is its capability to capture complex atmospheric phenomenon like wind directional shear. This approach was used to study hypothetical accidental release of radionuclides in nocturnal atmosphere which generates maximum wind directional shear. The results of dispersion in terms of dispersion coefficients were in good comparison with that of experimental findings in the available literature. The resulting ground level concentrations of radio-nuclides and radiological dose contours were also compared with those based on approach analogous to Gaussian Plume Model (GPM). The exercise proved that how misleading results would be if we ignore wind directional shear in stable atmosphere. The second approach is based on a state of the art solution. It involves the coupling of an Eulerian meteorological model (RAMS) with LSPM. The meteorological model is responsible to provide meteorological input to LSPM at each grid point and at each time step. This computational technique was used to simulate a hypothetical accident at a proposed site for Nuclear Power Plant. The meteorological output of the modeling system was compared with observed values. The comparison proved the efficacy and reliance of the approach. This computationally intensive but effective strategy is quite capable of supporting a real time decision making system for tackling nuclear emergency.
