Aedes aegypti also known as Asian tiger is the vector responsible for Dengue fever in whole South Asia. Approximately 50-100 million people are at risk from this disease. Pakistan is also endemic for this disease. The need is to control the vector responsible for this disease. Chemical control by Indoor residual spraying and Insecticides treated nets is used for this purpose but this vector has acquired resistance for insecticides. Among alternates, one is the herbal control by phytochemicals but the use of direct extract may be toxic for non-target population, hence the present study is planned to evaluate the larvicidal efficacy of neem seed oil and leaves extract Nanoemulsion against Aedes aegypti. LC50 was 10.6(20.7-3.9) after 48 h. Tween 20 based high energy nanoemulsion of neem seed oil was obtained by ultrasonication which was found stable at room temperature. Larvicidal efficacy of neem seed oil nanoemulsion having size 175nm with ratio 1:3 of oil and surfactant was 95%. It was found more ecofriendly, low-cost and effective against Aedes aegypti larvae. LC50 value shows good larvicidal potential of neem seed oil nanoemulsion as compare to neem leaves extract nanoemulsion after 48 hours. P values (p<0.05) also show the significance of results

محمد ثانی حسنی
ان سطروں کے لکھتے وقت مولانا سید ابوالحسن علی ندوی کے عزیز بھانجے جناب محمد ثانی حسنی کی وفات حسرت آیات کی اندوہناک خبر ملی، ان کو مولانا علی میاں اپنے فرزند کے برابر سمجھتے رہے، وہ اپنی متانت ، سنجیدگی اور خاموشی کی وجہ سے اپنے حلقہ میں بڑی قدر کی نظر سے دیکھے جاتے تھے، بڑے اچھے اہل قلم بھی تھے، ان کی کتابوں میں ایمانی حرارت و حمیت جلوہ گر رہتی تھی، ان کی وفات سے دارالمصنفین بھی سوگوار ہے، اس لیے بھی کہ یہاں جو سیمینار ہورہا ہے اس کے روح رواں مولانا علی میاں اور ان کے دست و بازو مولانا رابع ندوی تھے، جو مرحوم کے منجھلے بھائی تھے، ان کی سوگواری سے ہمارے سیمینار کی فضا بھی غم ناک رہے گی، دعا ہے کہ مرحوم کو کروٹ کروٹ جنت نعیم اور ان کے سوگوارماموں، بھائیوں اور بچوں کو صبر جمیل عطا ہو۔ (صباح الدین عبدالرحمن، فروری ۱۹۸۲ء)

 

From Jihad to Salam in Pursuit of Political Change: A Perspective based on Qur’ānic Sources

The political reality of many countries in the Muslim World is untenable and reforms and change is absolutely necessary. This article argues that use of force and violence for political change is making things worse as one can witness in Syria and Iraq. The article advances a Qur’ānic perspective on the desirability of peace as a goal and peaceful means as instruments of change. The article acknowledges that the Qur’ānic sanction for use of force to defend religious freedom prcludes the advocacy of pacifism but nevertheless the article does make a strong case for privileging peace over use of force.

Effect of Synectics Model of Teaching on Understanding of Mathematical Concepts of Students of Grade Eight

Mathematics education faces a lot of problems all over the world. Students often consider it a dull and a bore subject and their achievement in this subject is often poor.They only rely on memorization without paying attention to underlying concepts. Without learning concepts there is no comprehension and no cognitive development. Present study is an attempt to utilize and apply Synectics Model of teaching for mathematical concept understanding of students of grade eight. It was a type of quasi experimental study and Nonequivalent Control Group design was used. It was eleven-week long study. The subjects were two intact groups of 8th class, Control group (N=35) and experimental group (N=33) taken from two typical public high schools of district Haripur, KP, during session 2016-17. The instrument used in the study was a self-developed achievement test, developed on the idea of Constructed Response Questions (CRQ) from three units of 8th class mathematics textbook of KP Textbook Board Peshawar.A parallel form of the instrument from unit one was also constructed on the above mentioned pattern. The data was collected and analyzed using appropriate software. The statistical techniques as mean, standard deviation, t-test for independent and paired samples and repeated measure ANOVA were used. The results of the study revealed that after analogy integrated lessons students were able to: (i) redefine the concept in new way using their own words, (ii) relate learnt knowledge to their daily life, (iii) apply learnt knowledge in daily life, (iv) analyze and synthesize the concept, and (v) comprehend abstract concepts.
