Germination generally increases the nutritive value of seeds by modulating phytochemical composition depending on processing conditions. Therefore, the current study was conducted to compare the effect of emerging processing techniques such as ultrasound (US) and microwave (MW) on phytochemicals composition of sorghum sprouts. Overnight steeped sorghum grains were divided into four groups. The first group was designated as control without applying any treatment. Second group was subjected to ultrasonic treatment using 40% & 60% amplitude for 5 & 10 min. Third group was exposed to microwave treatment at 450 W & 700 W power levels for 15 & 30 sec. Similarly, fourth group was treated with combined MW & US application for different intervals. Microwave and sonication processing significantly improved the germination percentage and growth parameters, hence the phytochemical profile improvement. After germination, sprouts subjected to different quantitative analysis showed that with increased germination significant reduction was observed in anti-nutritional components such as alkaloid, saponin, tannin and phytate contents while contents of total free amino acids, sterols, and digestible proteins and carbohydrates increased. The oil yield and fatty acid composition increased with increasing amplitude of processing techniques. Antioxidant activities and HPLC analysis for individual phenolic compounds also improved significantly with high germination. In-vitro protein digestibility was significantly higher while bio-accessibility of polyphenol and flavonoid was insignificantly affected. From the present investigation, ultrasound processed treatment US1 (40% amplitude for 5 min) and microwave processed treatment MW2 (700 watt for 5 sec) are found paramount to improve the composition and bio-accessibility of phytochemicals through enhanced germination of seeds.

یونس رضوی
یونس رضوی(۱۹۲۷ئ) سیالکوٹ میں پیدا ہوئے۔ آپ نے ۱۹۴۹ء میں محکمہ انکم ٹیکس میں ملازمت حاصل کی۔ ۱۹۵۴ء میں فلم انڈسٹری لاہور سے رابطہ قائم کیا۔ آپ نے غزل ،نظم اور دیگر اصناف میں طبع آزمائی کی لیکن فلم انڈسٹری سے منسلک ہونے کی وجہ سے آپ کی زیادہ توجہ گیت نگاری کی طرف تھی۔(۷۳۳) ان کا شعری کلام ملک کے مختلف رسائل و جرائد میں چھپتا رہا۔ ایک شعری مجموعہ ’’میرے آنسو میرے گیت‘‘ ،زمزمہ پرنٹنگ پریس سیالکوٹ سے ۱۹۷۶ء میں شائع ہوا۔
یونس نے اردو شاعری میں کوئی نئی اور انوکھی راہیں دریافت نہیںکیں ۔بلکہ وہ اپنی شاعری میں روایت پسندنظر آتے ہیں۔ ان کی شاعری غم و اندوہ کی شاعری ہے۔ مگر ان کے ہر شعر کے پردے میں ایک ایسی چھپی ہوئی مضبوط انا کا وجود ملتا ہے۔ جو حوادث کی ستمرانیوں سے کبھی زخمی نہیں ہوتی۔ اور زندگی کا ہر آنے والا زخم انھیں پہلے سے کہیں زیادہ حوصلہ مند اوربا وقار بنا دیتا ہے۔یونس رضوی کا نمونہ کلام ملاحظہ ہو:
شبِ سیاہ مکمل شبِ سیاہ نہ تھی
تمہاری زلف کا سایہ بھی اس میں ڈالا گیا
بساطِ عشق کی بازی تمام ہار گئے
مذاقِ عشق ہمارا بلند و بالا گیا(۷۳۴)
غم زمانے کا متاع جسم و جاں تک آگیا
آگ کا شعلہ لپک کر آشیاں تک آگیا
کٹ تو جائیں گے شب و روز فراق ان کے بغیر
دکھ یہی ہے کہ رونق شام و سحر جاتی رہی(۷۳۵)

گردش دوراں کے ہاتھوں اس قدر مجبور ہوں
زندگی کی ہر مسرت سے میں کوسوں دور ہوں(۷۳۶)

تواریخ ادبیات اُردو کا فروغِ ادب میں کردار

تواریخ ادبیات اُردو کا فروغِ ادب میں کردار History is political, cultural or literary, is a social and social study. History writers have a great significance. If they are not unbelievable or not aware, then there are many misconceptions in the future. Therefore, history writers should always be obscurely, self-confident and powerful. The history and research capabilities of the writer in history are estimated. If a historian is not a researcher, then he is unable to present the truth. Similarly, a history trader does not have critical ability, he can try to review the facts. The historian not only parses events, but also offers a unique map of culture and culture. History of literature is especially described by culture and culture. History of the History of Urdu, it is known that historian literature is an important role in the promotion of Urdu. If the dates are removed, the understanding of literary literature will be impossible, that is why historians also play an important role promoting literature.

Use of Portfolio As a Tool for Assessing On-Going Development of Students Writing Skills

Action research is a qualitative study through which, one can improve the existing practice. Classroom teachers are actually action researchers, who can improve their teaching and the students' learning through critically reflecting on their practices. My interest evolved as a result of my dissatisfaction of the existing practice of the assessment system in my school, which, motivated me to work on this issue. Teachers consider teaching and assessment as two different aspects. Assessment is done at the end of the term or yearly basis which teachers judge the students learning. The problem is that teachers can't do justice to the students through summative assessments. In contrast, formative assessments help the teachers to assess students' progress on an on-going basis. It also helps teachers to improve their practices. We can try our best to use new and modern techniques and strategies in our classroom, but we cannot be effective teachers until and unless we assess the students' learning on an on-going basis. . This research study was done in my own school keeping in mind the possibilities and challenges of using portfolio as a tool for on-going development of the students' writing skills. The process approach was used to teach the students writing where both the mechanics and structure of the story were focused. Assessment of writing is integral to effective teaching and learning. Portfolio is a manageable, effective, and a fair way of assessing individual student's on-going development of writing skills. It helps the teachers to diagnose the students' needs and interests. In this way the teachers become more aware of them as individuals. That's why we say that it helps teachers to improve their teaching. Certainly when you know the students problems you will probably think about some ways to help them to re-solve those problems. Students need encouragement and qualitative feedback. This is the basic purpose of portfolio assessment so that students bring improvement in their work. Teachers feel it as a burden only because they are not aware of the advantages and the effective uses of portfolio assessment. Once they realize its effectiveness and its contribution in their teaching as well as the students' learning they would not feel it as a burden or extra work.
