قاری حفظ الرحمن
قاری حفظ الرحمن صاحب کم وبیش تیس برس سے دارالعلوم دیوبند میں درسِ تجوید وقراء ت کی خدمت انجام دے رہے تھے اب ادھر ایک عرصہ سے اس شعبہ کے صدر تھے۔ انڈوپاک کے قراء میں ان کی شخصیت بڑی ممتاز اورنمایاں تھی۔ چنانچہ عام طور پرانہیں شیخ القراء کہاجاتا تھا اورواقعی وہ اس کے مستحق تھے۔ فن میں مہارت وبصیرت کے علاوہ قدرت نے آواز بھی ایسی پرسوز وگداز دی تھی کہ جہاں کہیں پڑھتے تھے معلوم ہوتاتھا کہ لحنِ داودی کے نغمے برس رہے ہیں اور فضا سرتاپا سماعت بن گئی ہے۔فالج میں کئی برس سے مبتلا تھے لیکن کام چل رہا تھا۔ آخروقت موعود بھی آپہنچا اور رباب ہستی بے نغمہ وصوت ہوگیا۔اﷲ تعالیٰ ان کی قبرٹھنڈی رکھے اورمغفرت وبخشش کی نعمتوں سے نوازے۔

Coronary artery stenosis bypass by using radial artery is good techniques which have longer outcomes. In coronary artery bypass grafting (CABG) the radial artery has several advantages. The radial artery has a thick muscular wall which is more susceptibleto contraction from the competitive flow. As compared to the open harvesting technique endoscopic harvest of the radial artery has long lasting cosmetic results it also reduces the post-operative complications. The purpose of the study is to compare the two harvesting techniques and compare the short term and long term results related to intra-operative and post-operative outcomes Methods: This is retrospective study (In Queen Alia Heart Institute, Amman, Jordan) to compare endoscopic radial artery technique versus open technique by reviewing patients files through a period between June 2013 and June 2018. Total 50 patients of CABG surgery was selected they were divided into two groups. Group A includes endoscopic radial harvest (n= 10) and Group B includes open harvest (n=40). Data was collected on predesigned Performa. Data were entered and analyze through IBM SPSS 22.0 Results: There was insignificant dissimilarity between the pre-operative outcomes between groups. The Post-operative outcomes were almost same in both groups except hand numbness (P-value<0.005). The comparison of intraoperative outcomes like harvest time between both groups indicate that the mean harvest time in group A was shorter than group B (39.20 + 3.73 Vs 51.90 + 2.09, P-value=0.000). The operative time in group A was higher than the group B (306.0 + 11.6 Vs 278 + 4.25 p-value=0.00). The hospital stays in both groups were insignificantly different (p = 0.09) Conclusions: Endoscopic radial artery harvest is best suited technique for CABG surgery as it significantly decreases the harvest time as well as hospital stay. It is also proven that it is safer, less painful and better wound appearance technique with exceptional outcomes based on positive surgical experience.
Hands-on activities make vibrant connections between abstract concepts and material examples in the science classroom. Therefore, this study aimed to explore the efficacy of specially designed hands-on activities to develop conceptual understanding of properties of air in science. A qualitative research design was employed to investigate the research question. Six students of grade VI from a Bright Future School (Pseudonym), a private school in Hunza participated in this study, among which three were girls and three boys. Pre and post- test were undertaken to explore students understanding about properties of air before and after teaching through hands-on activities. Moreover, five activities were designed and implemented to develop conceptual understanding of students about four properties of air such as air exists everywhere, air occupies space, air has weight, and air exerts pressure. More specifically, I was interested in examining how the designed hands-on activities act as an effective pedagogical tool in the science classroom. Findings of the study revealed that students who had weak and partial understanding in pre-test developed better and deep understanding in the post-test. It was also found that each activity designed and implemented can indeed offer distinct benefits in developing in-depth understanding, removing alternative conceptions along with promoting student active engagement and interest in valuable ways. The study also indicates that teacher plays a pivotal role in developing and effective implementation of hands-on activities. The activity work best, if the teacher has a deep understanding of the instruction, plays the role of facilitator and be able to use multiple methods of assessment to assess the effectiveness of the activity while teaching and learning science. The results of the study also bring valuable insights into how teacher successfully develop and implement hands-on activities effectively in the science classroom. For instance, it was difficult for me to develop and implement hands-on activities successfully without pedagogical knowledge and support from the supervisor. Thus, it brings implications for science educators and teachers that teachers should provide opportunities and encourage participating professional development programs and calls for the change in teaching and learning processes in a science classroom in the context of Hunza-GB.
