Pakistan produces massive amount of crop residue with high bulk volume and low density. This residue is difficult to handle, transport, and store. Only a little amount of energy is recovered from it due to inefficient techniques while remaining is wasted. Farmers often use on site disposal via burning to remove this residue which results in release of enormous amount of harmful gases to the environment due to incomplete combustion. There is need to have modern technologies to convert loose biomass residue into dense, well-shaped product like briquettes that would be easy to burn and sustainable to the environment. Moreover, these energy blocks in the form of briquettes can be utilized in energy extraction systems as an alternative of wood and expensive fossil fuels (crude oil, natural gas and coal). Specially, deployment in electricity power generation plants can provide huge relieve from the energy shortage in the country. The present study shows the development, optimization and performance evaluation of intermediate pressure briquettes forming machine, working on mechanical piston press technology with production capacity ≈300 kg/m3 and produces 85 mm diameter briquettes. To develop it locally available material, technology and man power was used to reduce the cost of machine. Concavity of machine’s die was optimized at 20° tapered. It was optimized based on durability, density and compressible strength of briquettes at 20% moisture content, 9 mm particle size and 300° Cmould (die) temperature using a specific binder ratio i.e. crop residue: slurry: starch = 12:3:1. Comparison of Exhaust gases (CO, CO2, NOx and SO2) analysis of the raw biomass and briquettes showed that burning of briquettes released from 43 to 6 times less toxic gases as compared to their loose straws and conventional solid fuels. Payback period and benefit-cost ratio (BCR) of briquettes formation plant were calculated as eight months and 1.25 respectively.So, economical, environment friendly and good quality solid fuel was produced from crop residue.

ملکی ترقی میں نوجوانوں کا کردار

ملکی ترقی میں نوجوانوں کا کردار
نحمدہ ونصلی علی رسولہ الکریم امّا بعد فاعوذ بااللہ من الشیطن الرجیم
بسم اللہ الرحمن الرحیم
صدرِذی وقار، معزز اسا تذہ کرام اور میرے ہم مکتب ساتھیو!
آج مجھے جس موضوع پر لب کشائی کا موقع فراہم کیا گیا ہے وہ ہے:’’ملکی ترقی میں نوجوانوں کا کردار ‘‘
جنابِ صدر!
ملک کے ساتھ محبت وطن کے ساتھ محبت ہوتی ہے اور وطن سے محبت کی تائید دینِ اسلام بھی کرتا ہے۔ وطن اور ملک کے ساتھ ہمارا قلبی لگاؤ اس بات کا متقاضی ہے کہ ہم اس کی ہر شے کی حفاظت کریں۔ اس کے تحفظ اور بقا کی خاطر انتھک محنت کر یںاس کی ترقی اور عروج کے لیے جہد مسلسل کریں۔
جنابِ صدر!
ملک کی ترقی سے مراد اشجار وا حجار کی ترقی نہ ہے ،صحراؤں دریاؤں کی ترقی نہ ہے، کھیتوں اور کھلیانوں کی ترقی نہ ہے، بلکہ اس سے مراد عوام النّاس میں شعور کو اجاگر کرنا ہے۔ اچھے برے کا فرق واضح کرنا ہے اپنے تعلیمی نصاب کو معاشرتی اقدار کے مطابق ترتیب دینا ہے، باشندگان ملک و ریاست کا عروج ہی دراصل ملک کی ترقی اور عروج ہے۔
جہانِ تازہ کی افکار تازہ سے ہے نمود
کہ سنگ و خشت سے ہوتے نہیں جہاں پیدا
صدرِذی وقار!
ملک کی ترقی میں نوجوان ایک عظیم کردار ادا کر سکتے ہیں وہ اپنی سوچ کومثبت کریں،پروپیگنڈہ پراکسانے والی سوچ سے کنارہ کش ہو جائیں۔ حصولِ تعلیم کے لیے اپنے آپ کو وقف کر دیں۔ اپنی زندگی کا کوئی لمحہ ضائع نہ کریں۔ ان کے انہی اقدام سے ہمارا ملک ترقی یافتہ اقوام کی صف میں کھڑا ہو جائے گا۔
جنابِ صدر!
ملکی ترقی میں نوجوان کا کردار انتہائی اہمیت کا حامل ہے ،نوجوان کسی قوم کاعظیم سرمایہ ہوتے ہیں۔ اقوام ان سپوتوں...

الشيخ حافظ محمد إدريس وأسلوبه في تفسيره كشاف القرآن

Pashtun Ulama have always been in the service of Islam. The origin of Pashtun people in Pakistan is the province of Khyber Pukhtunkhwa formerly known is North West Frontier Province (NWFP). Pashtun Ulama have served Islam on different fronts; some have done Jihad against the non-Muslims, some of them have offered their services in the field of Islamic education, ie, teaching in Madrassas, while some have served Islam via their writing commentary of Qur’ān, explanation of Ḥadīth and juristic problems. This article discusses the worthy contributions of one of the great commentators of Qur’ān Shaykh Ḥāfiẓ Muḥammad Idrīs, who belonged to Mardan in the Province of Khyber Pakhtunkhwa, He lived in the 19th century. The article encompasses a detailed biography of the writer and his worthy contribution in serving Qur’ān, Islam and Muslims focusing on his commentary on Qur’ān in Pashto language named as “Kashshāf Al Qur’ān”. The method used for the research is descriptive and qualitative. The review literature showed that such an esteemed and vigorous scientist of different sciences of Qur’ān and his valuable contributions are out of the reach of scholars and libraries that may lead to an irreparable loss of the Islamic legacy. The study came up with the outcomes of his efforts in the field exegesis of Qur’ān, and the way and pattern he followed in interpreting different meanings of the revealed literature. The study would help out Islamic scholars and will enrich the domain of the Qur’ān’s research with new thoughts and viewpoints

Analysis of Relationship between Need Based Training and Assessment Reduction of Professional Obsolescence PO in Pakistan Banks.

According to the emergent case of Web services in Pakistani banking sector, two types of preconditions are investigated: technological preconditions and organizational preconditions vis-a-vis technically competent human resource. Based on these, a set of qualitative and quantitative research methods were carried out beside the bank direction, commercial staff and subscribed customers to technology based banking services. The research illustrates that centralized architectures, fragmented information systems, organizational rigidity, level of technological know-how and disregarding user's implication could be factors of slowness (or failure) in implementing technology based banking services. E-banking has to be a delivery channel that replicates and replaces many of the physical functions a bank currently performs. Hence, e-banking now becomes a virtual banking counter that the individual and corporate customer to carry out the regular activities. Even e-banking services are more electronic-based, but, it still strongly supports banking activities, therefore communication, transaction and distribution (Peterson, Balasubramanian and Bronnenberg, 1997). There are number of challenges that need to be faced by Pakistani banks, however, the opportunity in this industry is high due to the current trend especially application and development of ICT. The tremendous advances in technology and the aggressive infusion of information technology had brought in a paradigm shift in banking operations. Internet banking that has revolutionized the banking industry world wide has turned out to be the nucleus issue of various studies all over the world. However there has constantly been a literature gap on the issue in Pakistan. Exploring online banking customer requirements allowed the definitions of service criteria assuring customer satisfaction at the time of realization and so the factors regulating the quality level of Internet banking services. Analyzing voice of the customer and building a transformation framework bringing it into practice are the leading steps of the methodology and the most important factors in regulating the level of quality of internet banking services. Dove (2004) holds the opinion that failure to adapt to change in terms of skills development is professional obsolescence. Khan (2004: Dawn) says that influx of insincere, non professional, incompetent recruitees in banks in the aftermath of privatization badly affected the banking industry. This fact has been verified by Grip and Zwick (2001:4) who opined in their study on "the employability of low-skilled workers in the knowledge economy", changes in technology and occupation also spur shift in the kinds of skills needed to serve a specific job, and any neglect to update the skills leads to professional obsolescence. The continuous improvement in skills and knowledge in the Banks is vital and this view is supported by Grip and Zwick (2001:4) and they state that "Both the upgrading of the skill level and the shifts in the type of activities may deteriorate the applicability of skills the workers acquired in the past". The banks in Pakistan are facing new challenges due to globalization of financial markets. The international banks are equipped with modern technology, innovative products and services, skilled and knowledgeable human resource to capitalize on the major and valued segment of the clientele. The local banking industry is directionless. It is due to lack of required skills and knowledge the employees need to possess to perform their duties efficiently. Srivastava (2003:68) describes about the emerging competitive environment where performance of an individual depends upon different types of skills and knowledge and one of them is developing problem solving skills. Sridhar (2003:31) states that genuinely identified training needs will address the issue of skills development. Khan (2004:Dawn) proffers one significant remedy to improve the performance of banks which is institutionalization of HRM and it entails placement of best man to best assignment, updating his/her knowledge through refreshing courses, seminar on emerging banking and financial problems thereby heading towards reduction in professional obsolescence. Need-based trainings are the major tool to equip the human resource so as to make Pakistani banks sustainable and competitive apart from other reform measures like further strengthening of Prudential Regulations,
