سیّد محفوظ علی بدایونی مرحوم
اسی مہینہ میں ۲۰؍ اکتوبر کو ایک اور پرانے ادیب سید محفوظ علی صاحب بدایونی مرحوم نے فالج کے مرض میں انتقال کیا، مرحوم بدایوں کے ایک قدیم اور شریف خانوادہ کی یادگار علیگڑھ کالج کے ممتاز تعلیم یافتہ اپنے دور کے نامور ادیب اور علی گڑھ منتھلی، اولڈ بوائے، دکن ریویو، نقیب اور ہمدرد کے دور اول کے ممتاز لکھنے والوں میں تھے اور اس زمانہ میں ان کے مضامین بڑے ذوق و شوق سے پڑھے جاتے تھے، وہ سنجیدہ اور ظریفانہ دونوں طرز کے شگفتہ نگار ادیب تھے، غالباً متفرق مضامین کے علاوہ کوئی مستقل قلمی یادگار نہیں چھوڑی، ادھر برسوں سے علم و ادب کا کوچہ چھوڑ کر خلوت گزینی کی زندگی اختیار کرلی تھی، وہ ابتداء سے بڑے دیندار اوظاہری وضع و قطع میں بھی پابند شریعت تھے، ناواقف شخص ان کو دیکھ کر انگریزی تعلیم یافتہ ہونے کا گمان بھی نہیں کرسکتا تھا اور یہ رنگ برابر گہرا ہوتا گیا، آخر میں بڑا ذوق و شوق اور بڑی کیفیت پیدا ہوگئی تھی اور اسی پر ان کا خاتمہ ہوا، اﷲ تعالیٰ اس طالب آخرت کو اپنی رحمت و مغفرت سے سرفراز فرمائے، ہماری پرانی بزم ادب کی شمعیں ایک ایک کرکے بجھتی جاتی ہیں، جو باقی ہیں وہ بھی شمع سحر ہیں اور جب تک ہیں غنیمت ہیں، ان کے بعد یہ روشنی بھی نظر نہ آئے گی۔
مرحوم مولانا شبلی مرحوم کے زمانہ میں علی گڑھ میں پڑھتے تھے، اس نسبت سے ان کو میرے ساتھ بھی یک گونہ محبت سی تھی اور خصوصیت کی ملاقات مرحوم دوست مولانا عبدالماجد صاحب بدایونی کی وساطت سے ہوئی اور ایسی ہوئی جو ان کے اخیر لمحہ تک قائم رہی، وہ اپنے مذہبی انقلاب کا ایک عجیب ظریفانہ واقعہ بیان فرماتے تھے۔

Sindh remains a center of great Islamic scholar in early ages till now, scholars of Sindh served in all the fields of Islamic studies. Among Islamic Scholars of Sindh who have left unmatchable repute Sayyed Badi‘ud-Din Shah alR┐shidi, is one of them. He was at home in Quran and its sciences, Hadith and its science, Fiqah and its science. He was author of many books among them was Badi‘ul Taf┐sir, Badi‘ul Taf┐sir (اافتلرس دبعی (currently Contains 11th volumes including excurses (دقمہم (this tafsir adheres to the following sequence: (1) Tafsir of Quran by the Sunnah. (2) Tafsir of Quran by Language. (3) Tafsir of Quran by Opinion. Badi‘ul Tafasir is worthy to get the award of best Sindhi tafsir of this time. In this manuscript it is proved that Badi‘ul Tafasir is best collection of Religious commandments which has been described in detail according to jurisprudential Viewpoints and qualities.
A huge amount of electrical energy in Pakistan is lost due to inefficient generation and distribution of power. [13] This project aims to address a very specific problem in this regard which is the energy conversion losses in power converters used with systems of renewable energy generation. The main problem that is being looked into is how the efficiency of an Isolated DC-DC Boost Converter can be improved. Addressing this issue helps in making effective use of renewable energy sources which in turn helps in reducing the energy deficit. To improve upon the design of an Isolated DC-DC Boost converter, it is imperative that first an in-depth study of the already existing designs be carried out. A detailed literature review helped in identifying areas that can be worked upon to increase efficiency. The major losses that occur in an isolated converter come from core and copper losses in its high frequency (HF) magnetic components that are the inductor and transformer. Apart from that, MOSFET losses and diode rectifying losses are also quite significant if chosen poorly. Hence, to increase efficiency, the most important part is an optimized design of HF components, careful selection when it comes to MOSFETs and diodes and finally selecting an appropriate converter topology. Increasing efficiency of HF magnetic components needs a rigorous analysis of design methodologies used to implement them. It was identified that some of the main factors involved in that were core material and geometry and its winding methodology.The killer for inductor and transformer are the leakage inductance and AC resistance which occur due to proximity and skin effect. It was identified that the main losses occur due to the winding method and the type of copper winding geometry. After an in-depth study and comparison between different winding types and methods, it was realized that copper foils help in reducing skin-depth effect and interleaving the windings would help in dealing with proximity effect. Interleaving is when primary windings of the transformer are sandwiched between secondary windings. To validate this design, first a theoretical analysis was carried out after which this design was implemented xi and tested in the lab where significantly low AC resistance and leakage inductance was observed.The major challenges in this project in the design phase were to identify methods for inductor and transformer construction. For transformer design, from analysis it wasdecided to implement interleaved windings but it was challenging to understand how the windings will terminate and physically implementing the windings without any gaps in etween. An unexpected challenge during transformer implementation was soldering the winding terminals using a high wattage soldering iron. This was because the solder has to be minimal to avoid any bumps. Another tight spot faced was while procuring material for the project as most of the required components were not available locally and that led to slight delays in the implementation phase. The converter proposed after the design and analysis has a theoretical efficiency of 97%. There can be a huge impact in utilizing renewable energy effectively if a practical use of this converter is carried out. However, to validate this research, the next step would be to implement the proposed device and computing its actual efficiency. Careful and precise implementation of the design can potentially achieve the calculated efficiency because of the design considerations taken into account. This can then be taken forward to local stakeholders such as the Alternate Energy Development Board (AEDB) as using locally designed and implemented converter will have a significant impact on the cost and benefit breakdown of sustainable energy projects being deployed
