ڈاکٹر محمد ایوب قادری

ڈاکٹر محمد ایوب قادری
پاکستان وبھارت کے علمی اور دینی حلقوں میں یہ خبر بڑے رنج وغم کے ساتھ سنی گئی کہ۲۵/نومبر۱۹۸۳ء کوپاکستان کے ایک نامور ادیب،مصنف اور مؤرخ ڈاکٹر محمد ایوب قادری کراچی میں ٹریفک کے ایک حادثے میں جاں بحق ہوگئے۔ وفات کے وقت ان کی عمر۵۶برس کے لگ بھگ تھی۔
قادری صاحب روہیلکھنڈ کے مشہور تاریخی قصبے آنولہ کے رہنے والے تھے۔ان کی ابتدائی تعلیم بدایوں اوربریلی میں ہوئی۔تقسیم ملک کے بعد موصوف کراچی چلے گئے۔کراچی جاکر انھوں نے اپنی تعلیم جاری رکھی اوربالآخر اردو کالج کراچی میں شعبۂ اردو میں لیکچرار مقرر ہوئے اور محنت،لگن اورخلوص کی بدولت آخر میں شعبۂ اردو کے صدر بن گئے۔
قادری صاحب کوروہیلکھنڈ کی تاریخ، رجال اور اماکن پربڑی دسترس تھی۔اس کے علاوہ۱۸۵۷ء کی جنگِ آزادی کے ہیرو ان کی تحقیق کا محور تھے۔ انھوں نے مخدوم جہانیاںؒ کاایک تذکرہ لکھا اورمآثرالامراء کااردو میں ترجمہ کیا۔ مرحوم نے مجلہ اردو کالج کراچی کے کئی شاندار نمبرنکالے۔پاکستان اوربھارت کے علمی وادبی رسائل میں ان کے مضامین اکثرچھپتے رہتے تھے۔
۲۵/نومبر کی شام کو موصوف اپنے گھرواقع شمالی ناظم آباد سے چلے۔ابھی انھوں نے بمشکل سو سواسوگز کا فاصلہ طے کیاہوگا کہ ایک ویگن ان کے سرسے ٹکرا گئی اورموصوف موقع پرہی جان بحق ہوگئے۔
یہ بھی عجیب بات ہے کہ ان کے ایک حقیقی بھائی ابومعاویہ نعمت اﷲ قادری بھی ۲/فروری۱۹۸۱ء کولیاقت آباد کراچی میں ٹریفک کے ایک ایسے ہی حادثے میں جاں بحق ہوئے تھے۔ابومعاویہ کودیکھ کرقرنِ اوّل کے مسلمانوں کی یادتازہ ہوتی تھی۔انھوں نے اس مادی دور میں اپنے تمام بچوں کودینی مدارس میں تعلیم دلوائی۔
یہ دونوں بھائی بڑی خوبیوں کے مالک اور اعلیٰ انسانی اوصاف سے متصف تھے۔اﷲ تعالیٰ ان کومغفرت وبخشش کی نعمتوں سے سرفراز فرمائے۔

Plating versus Ilizarov Technique for Complex Tibial Plateau Fractures: A Comparative Study on Functional Outcome and Patient Satisfaction

ObjectiveTo compare clinical and functional outcomes and complications of open reduction internal fixation (ORIF) by plating and Ilizarov technique in complex tibial plateau fractures. MethodsThis study is a randomized clinical trial accompanying 56 patients having Schatzker type V and VI tibial plateau fractures. We divided patients into two groups for management. Group I; open reduction internal fixation versus Ilizarov technique (Group II). We conducted at the Orthopedics Department, Jinnah post-graduate medical centre, Karachi, from April-2018 to Oct2020. The endpoint assessed patients’ satisfaction and clinical and functional outcomes up to an 18-month follow-up. ResultsThe aetiology of tibial fracture was mainly road traffic accidents (RTA); 17 (70.9%) in ORIF versus 23 (71.8%) in the Ilizarov group. According to clinical outcomes, excellent extension lag was achieved in 100% of patients in both groups. Most patients had excellent knee flexion, thigh atrophy and instability outcomes (54.1% vs 59.37%, 87.5% vs 81.2% and 83.3% vs 87.5%). The functional outcome assessment was done and recorded for 18 months of follow-up. There was no significant difference in normal walking, stair climbing, squatting, jumping and duck walking between the groups. The overall rate of complications was similar; 11 (45.8%) in ORIF versus 17 (53.12%) in the Illizarov group (p-value 0.78). ConclusionOur study concludes that there is an excellent clinical and functional outcome found in both procedures.   DOI: https: //doi. Org/10.59564/amrj/01.01/008

Comparative Study of Enriched Compost, Inorganic Fertilizer and Pgpr on Soil Fertility Status and Physiology of Wheat Triticum Aestivum L.

Present investigation was aimed to formulate an efficient phosphatic bio-fertilizer to supplement or substitute chemical fertilizers and to evaluate its effect on the availability of P for growth and yield of wheat. For this purpose rock phosphate enriched compost (RPEC) was prepared and the effect of plant growth promoting rhizobacteria (PGPR) was evaluated for phosphorus availability through composting. Impact of PGPR alone or in combination with different (organic and inorganic) fertilizers were studied on wheat crop grown under natural conditions of field and axenic condition of pots. In the first experiment, poultry litter alone and in combination with rock phosphate was composted with and without PGPR (Pseudomonas sp. and Proteus sp.) inoculation in pits for 120 days (d) and shuffled with 10 d interval for proper aeration. The RPEC prepared by the combination of poultry litter, rock phosphate (RP) and Pseudomonas sp. inoculation showed maximum total phosphorus, available (Mehlic-3 extracted) phosphorus, microbial biomass (carbon and phosphorus), but lower total organic carbon, total nitrogen and carbon/nitrogen ratio over poultry litter without inoculation and addition of RP. Pseudomonas sp. enhanced P solubilization from rock phosphate (RP) and showed 79% higher P availability from RP added poultry litter over un-inoculated treatment on 120th day of composting. Experiments under natural condition of field as well as under axenic condition in pots were conducted for two consecutive years. The residual impact of the treatments were also studied on soil chemical and biological properties. The wheat seeds were surface sterilized and inoculated with Pseudomonas sp. (Accession No. KF307201) and Proteus sp. (Accession No. KF307202) at the rate 106cells ml- 1 prior to sowing. Seven treatments; simple poultry litter (SPLC), Rock phosphate enriched compost (RPEC1, inoculated with Pseudomonas sp. during composting), RPEC2 (solubilized with Proteus sp. during composting), Rock phosphate, Half recommended dose of inorganic P fertilizer (HDP) and Full recommended dose of inorganic P fertilizer (FDP) were applied with and without seed inoculation of PGPR (Pseudomonas sp. and Proteus sp.). Average of two year data on field and pot experiments showed increase in plant height, number of tillers, grain yield, dry matter yield, seed phosphorus and plant P-uptake with application of Pseudomonas sp. solubilized rock phosphate enriched compost compared to recommended dose of inorganic (single super phosphate) fertilizer. The chlorophyll content and phytohormones (Indole Acetic Acid and Gibberellic Acid) in flag leaves were also enhanced with application of rock phosphate enriched vii compost. Post-harvest soil phosphorus availability, nitrate nitrogen content, extractable potassium, alkaline phosphatase activity and microbial biomass increased with the application of rock phosphate enriched compost over full recommended dose of inorganic fertilizer. Moreover, seed inoculation with PGPR (Pseudomonas sp.) also significantly increased yield and yield parameters of wheat and post-harvest soil properties over un-inoculated treatments. Economic analysis in terms of value cost ratio showed 3.23:1 from the treatment where RPEC in combination with Pseudomonas sp. seed inoculation was applied. Thus rock phosphate enriched compost can be used as an alternate to inorganic phosphatic fertilizers and seed inoculation with Pseudomonas sp. can enhance wheat growth and yield applied in combination with enriched compost. In another experiment, wheat (AGS2060) root phosphatase activity was also determined in presence of different P sources; compost (C), rock phosphate (RP), single super phosphate (SSP), C + RP, C + SSP, RP + SSP, C +RP + SSP and results showed maximum (447%) increase in P mineralization with compost (C) grown roots over SSP. It was inferred that compost is the best source to mineralize organic P for better crop production.
