Extensive field surveys were conducted to collect Pierid butterflies and their host plant flora from all districts (Jhelum, Rawalpindi, Chakwal, Attock, and Islamabad) of Potohar region of Punjab Pakistan during January 2012 – February 2015. A total of 1839 specimens belonging to 19 species were identified under two subfamilies and ten genera. The identified species were Catopsilia pyranthe, C. crocale, C. pomona, Gonepteryx mahaguru, G.rhamni, Colias fieldii, C. erate, Eurema laeta, E. hecbae, Delias eucharis, Pontia daplidice, Belenois aurota, Pieris rapae, P. canidia, P. brassicae, Ixias pyrene, Colotis amata, C. etrida, and C. protactus. Among these, eight (08) species; Delias eucharis, Belenois aurota, Pieris rapae, Colotis amata, C. etrida, Gonepteryx mahaguru,G.rhamni and Colias erate were reported for the first time from Potohar region. The current study as being first biogeograhical study from Potohar region recognizes the elements from all biogeographical regions of the world. However, the Afrotropical and the Aust- oriental elements remain dominant. Among reported host plants, 21 species of 15 plants [Capparis aphylla, (family Capparaceae), Cassia fistula, Sesbania grandiflora (family Fabaceae), Salvadora oleoide (family Salvadoraceae), Loranthus longiflorus, Scurrula pulverulenta, (family Loranthaceae), Rhamnus triquetra, R. purpurea (family Rhamnaceae), Brassica napus, B. oleraceae, B. oleraceae var. italica, B. campestris, B. officinalis, Raphanus sativus, Eruca sativa (family Cruciferae)] are new records for Pakistan, However six (06) host plants [Lepidium pinnatifidium, Coronopus didymus, Arabidopsis thaliana (family Cruciferae), Cassia occidentalis, Medicago sativa, and Melilotus officinalis (family Fabacae)] are new addition to world''s host plant list of Pierids fauna. GIS map distribution of all the butterflies along with their host plants is provided for the first time from pakistan.Taxonomic keys for subfamilies, genera and species were also prepared. From the study area, the complete list of host plants of family Pieridae up to species level has been provided first time. In the present study, relative abundance and percentage of different butterflies were found in each district. In district Jhelum, Pieris brassicae showed highest relative abundance (0.18) and percentage (18.12), with its host plant Brassica oleraceae (0.25) and percentage (25) respectively. In district Rawalpindi, xvii Pontia daplidice showed highest relative abundance (0.20) and percentage (20.05) with its host plant Lepidium pinnatifidium (0.28) and percentage (28). In the districts Attock and Chakwal, Catopsilia pomona showed highest relative abundance (0.19) and percentage (18.99) with host plant Coronopus didymus (0.38) and percentage (38) and Lepidium pinnatifidium, Brassica napus, Brassica compestris (0.16) and percentage (16). In district Islamabad, Pieris canidia showed highest relative abundance (0.23) and percentage (23.22) with its host plant Coronopus didymus (0.28) and percentage (28). Diversity of Pierids butterflies and their host plants was calculated by using five diversity indices namely; Simpson, Shannon, Evenness, Menhinick, Margalef and Equitability. The values from five districts of Potohar region were within suitable range of Simpson index i.e. between 0.8-0.9 for butterflies species and host plant which shows their stable community in the region. However, Shannon and Weiner values of five districts revealed that Potohar region has rich host plant flora and butterfly fauna with even distribution as most of values were between 1.8 and 2.4. In Potohar region, the values of evenness index ranges between 0.5-0.8 which shows even distribution of butterfly''s species and host plants in the region. The overall calculated values of Menhinick index of butterfly''s species were between 0.5- 0.7 which showed high diversity of butterfly''s species and host plants within the region. The Margalef and equitable index values showed high species richness for butterflies and host plants in the region. Highest species richness were recorded in Rawalpindi and Islamabad districts (2.336-2.023) and comparatively low species richness were recorded in district Attock (1.516) and for the host plants highest specie richness were recorded in the same 2 districts i.e. 1.83 and in Rawalpindi and Islamabad.

آیت اﷲ خمینی

علامہ آیت اﷲ روح اﷲ خمینی
یہ سطریں زیر تحریر تھیں کہ اسلامی جمہوریہ ایران کے بانی علامہ آیت اﷲ روح اﷲ خمینی کے انتقال کی خبر ملی، وہ اسلامی نظام کے علمبردار ہونے کی بنا پر قید اور جلاوطن کیے گئے، ایران سے شہنشاہیت کا خاتمہ اور جمہوریت کا قیام نیز اسے مغربی ملکوں کی گرفت سے نکال کر اسلام کے راستہ پر ڈال دینا ان کا اہم کارنامہ ہے، اپنی آخری وصیت میں انھوں نے ساری دنیا کے مسلمانوں کو امریکی و روسی تسلط سے چھٹکارا حاصل کرکے باہم متحد ہونے، اپنے دست و بازو پر بھروسہ کرنے اور بتان رنگ و بو کو چھوڑ کر اخوت اسلامی کے رشتہ میں منسلک ہوجانے کی دعوت دی ہے، مگر اسلامی انقاب کے بعد ایران میں خون خرابہ ہوا، عراق سے آٹھ برس تک جنگ ہوتی رہی، حرم میں شورش بپا ہوئی، اس لیے ایران کے انقلاب کو نسلی و قومی سمجھا جانے لگا، مگر انھوں نے امریکی سفارتخانہ کو یرغمال بنانے کا اعلان کرکے ساری دنیا کو دم بخود کردیا۔
سلمان رشدی کے قتل کے فتوے سے وہ عام مسلمانوں میں بہت محبوب ہوگئے تھے، ایرانی انقلاب نے پھر ثابت کردیا کہ علماء اور مذہبی رہنما بھی قوموں کی تاریخ موڑ دینے کا کام انجام دیتے رہے ہیں، آج اسلامی ممالک مغربی حکومتوں کی کٹھ پتلی بنے ہوئے ہیں لیکن مرحوم خمینی کی جڑیں عوام میں بہت گہری تھیں، اس لیے بڑی طاقتیں ان کا کچھ بگاڑ نہیں سکیں، وہ انقلاب کے روز ہی کی طرح وفات کے دن تک عوام میں مقبول رہے، ان کی وفات بڑا سانحہ ہے، اﷲ تعالیٰ لغزشوں کو معاف کرے اور مرحوم کی مغفرت فرمائے۔ (ضیاء الدین اصلاحی، جون ۱۹۸۹ء)

الأصوات العربية الفرعية في الدراسات الصوتية

يهدف هذا البحث إلى المساعدة على التعرف على كيفية تركيب الألفاظ العربية من حيث إتيان الحروف المجاورة في بنائها، وعند جمع أربعة أو أكثر في التلفظ بها. ويعين على تمييز الألفاظ الأعجمية التي لها ألفاظ عربية. واتبع الباحث المنهج الوصفي التحليلي في إجراء البحث. وفي ضوء ما تم تناوله تم التوصل إلى النتائج الآتية: 1- أن تصنيف الحروف الفرعية إلى مستحسن ومستقبح راجع عند القدماء لمبدأ الكثرة والقلة، فما كثر استعماله كان مستحسنا، وما قل استعماله وصف بالاستقباح. 2- تمثل الحروف الفرعية ألوانا من الآراء يعكس اختلاف القبائل العربية آدابها، وهي من صور الأداء المعروفة، مما جعل العلماء يقومون ببيان خواصها الصوتية. 3- جاءت هذه الحروف لإحداث نوع من التناسق والإنسجام في البنية الصوتية.

Study of the Elementary Mathematics Curriculum of Class 7 As Implemented

The present study investigates the enactment of the mathematics curriculum in class 7 at a government school in Karachi. Using classroom observation, interviews of a teacher and sampled students and analysis of the curriculum document, the textbook and written work of the students, an attempt was made to understand how far the objectives of the elementary mathematics curriculum were being realised. Also, the constraints on the translation of these objectives from theory into practice were explored. The study focused on the curriculum statement', delivery' and enactment' of four lessons on the simplification of algebraic expressions, each followed by a test' question given to a mixed ability sample group from the class. It was discovered that the very generally stated curriculum was differently implemented in the textbook and by the teacher, which produced unnecessary conceptual and terminological confusion. When students received no help from the teacher, they drew upon their prior arithmetic knowledge. Upon probing, it was found that due to situational constraints, the teacher was herself unclear about the symbolic property of algebraic signs and procedures. A proper understanding of and distinction between operational symbols and quantity symbols was missing. Besides, the bilingual terminology, duplication was found to be an important complicating factor. Addressing the teacher's understanding of algebraic concepts can help reduce the gaps between the stated curriculum and the enacted curriculum. The research findings underlie the need for re-sequencing the curriculum objectives and textbook topics.
