آہ ڈاکٹر عبدالرّب عرفان!
قارئین معارف کو یہ سن کر بڑا افسوس ہوگا کہ ڈاکٹر عبدالرب عرفان ۳۰؍ اپریل کو انتقال کرگئے، وہ معارف کے بڑے قدر دانوں اور خاص مضمون نگار اور دارالمصنفین شبلی اکیڈمی سے گہرا تعلق رکھتے تھے، اردو، فارسی کے عالم اور ان زبانوں کی ادبیات کی تاریخ سے اچھی واقفیت رکھتے تھے، ہندوستان کے عہد اسلامی کی تاریخ پر ان کی نظر تھی، اس عہد کے سلاطین و مشائخ اور علماء و فضلاء کے حالات و تراجم سے ان کو بڑی دلچسپی تھی اور اس پر ان کے مضامین ملک کے بلند پایہ رسالوں میں شائع ہوتے تھے مگر معارف پر ان کی نظر عنایت زیادہ تھی۔ اس شمارے میں بھی ان کا ایک مضمون شامل ہے اور ابھی دو ایک اور مضامین میری فائل میں ہوں گے۔
میری ان کی ملاقات کبھی نہیں ہوئی مگر خط و کتابت رہتی تھی، ان کے خطوط سے اندازہ ہوتا تھا کہ ان کے دل میں میری کتنی قدر و محبت اور معارف سے ان کو کیسا والہانہ لگاؤ تھا۔ مجھے ان کے حالات زندگی سے کوئی واقفیت نہیں تھی ان کے ایک ہم وطن جناب فیروز حیدری کے خط سے معلوم ہوا کہ انہوں نے کامٹی کے ایم۔ایم ربانی ہائی اسکول سے میٹرک کا امتحان امتیازی نمبر سے پاس کیا تھا۔ اور مارس کالج ناگپور سے بی۔اے کیا تھا۔ پھر فارسی زبان و ادب میں ایم۔اے میں امتیازی نمبر ہی نہیں بلکہ گولڈ میڈل کے بھی حق دار قرار پائے تھے، ۱۹۶۱ء میں ودبھ مہاودیالیہ امراؤتی میں فارسی کے استاد کی حیثیت سے ان کا تقرر ہوا اور بہت جلد شعبہ فارسی کے صدر بنائے گئے، ۱۹۸۲ء میں ان کا تبادلہ ناگپور میں وسنت راؤناٹک گورنمنٹ انسٹی ٹیوٹ آف آرٹس اینڈ سوشل سائنسز (سابق مارس کالج) ہوگیا۔ ڈاکٹر عبدالرب عرفان طبعاً شریف، سادہ مزاج،...
The question of the end of morality is certainly as old as moral speculation itself. It is this question that prompted Aristotle speculating on moral or character virtue. Moral question is properly a human question since only human beings are expected to act in a given way and are subject to praise and reward or blame and punishment. We should remember that also God and angels are expected to act in a given way, but that would, strictly speaking, be the subject of moral theology and revelation, since without revelation depending only on reason, we cannot examine the acts of God and angels in order to determine how they should act. In short, it is only human beings who can be judged to act morally or immorally if we depend only on human reason, without the support of revelation. In the whole work, Stuart Mills and Jeremy Bentham stick on happiness, though each differ in approaches. Consequentialists are after the greatest happiness of the greatest number, by advocating on the struggle to that which may make man happy and avoid evil by all means. Aristotle on his side is on eudaimonism, where man is found to be happy but moral happy. Happiness for Aristotle should be reasonable, morally good and means should be maintained. This research is analytical by nature, where both qualitative and analytical methods have been implemented throughout the work. The work has been successful though some challenges could not be avoided. Finally, in doing or acting, man should observe virtue; and this is always doing good and avoiding evil.
Water and nitrogen (N) are the most important limiting inputs of maize (Zea mays L.) production in semi-arid environment. Irrigation regimes, N application timing and rate significantly influence maize growth and yield. To study effects of the nutrients in semiarid environment, two experiments were conducted. The crop was sown on August 1, 2009 and August 2, 2010 at the Agronomic Farm of the University of Agriculture Faisalabad, Pakistan. The Cropping System Model (CSM) CERES-Maize was used to predict crop growth and yield under semi-arid environment. In Experiment-I, effects of times of N application were studied with five N levels (100, 150, 200, 250 and 300 kg ha-1). In Experiment-II, effects of three irrigation regimes (normal, water deficit at vegetative and water deficit at reproductive stage) were studied with the five N levels. The times and rates of N significantly affected grain yield and the yield components. Effect of N was linear, quadratic and cubic. Results revealed that application of N at the rate of 250 kg ha-1 in three splits (at 2 leaves, 16 leaves and silking stages) produced the highest grain yield (8.38 t ha-1). At these levels maximum values of leaf area index (LAI), photosynthesis and all others yield components were achieved. In contrary, crop growth rate and biological yield increased up to 300 kg N ha-1. However, the biological yield at 300 kg N ha-1 was statistically similar with 250 kg N ha-1. The crop was more sensitive to water deficit at reproductive stage than at vegetative stage. Water deficit at vegetative stage reduced grain yield 14% while of grain yield was decreased 22% when crop faced water deficit at reproductive stage. The CSM-CERES-Maize application predicted crop growth and yield well. So, the model can be used as a research tool in semi-arid zone of Pakistan. The model predicted phenology of crop well with less MPD and RMSE. The model predicted grain yield very closely to that observed; RMSE ranged from 656 to 1586 kg ha-1 among all treatments. In nutrient stress treatments, time course simulations of the model for LAI were satisfactory in both experiments. Prediction of the model was excellent in treatments which had adequate nutrients supply. The value of d-statistics ranged from 0.56 to 0.99 for LAI. The model predicted TDM very close to the observed values having low RMSE with 0.97 to 0.99 d-statistics. The application of 250 kg N ha-1 in three splits i.e., 1/3rd N at V2, 1/3rd N at V16, and 1/3rd N at R1 stages with supplemental irrigation of 530 mm ha-1 is the best management practice for semi-arid environment.
