Agro ecological diversity and favorable environment have enabled Pakistan to harvest bulk of potato crop however facing problems of poor post harvest management practices and unavailability of superior raw material for the potato processing industry. A comprehensive study was planned to identify best packaging material and appropriate storage conditions for the premium potato variety. The present study has been divided in to three different phase to address specific objectives. The first phase of study encompasses physico-chemical, functional and processing attributes in prominent potato varieties. The selected variety was subjected to different post harvest storage conditions along with their processing parameters analysis in second phase of the study. The last phase of study evaluated the storage stability of premium variety under best results identified in the second phase. In the first phase of study, physical attributes (tuber size, geometric mean diameter, sphericity, surface area, firmness, specific gravity, total soluble solids, pH, sprouting %, tuber color) Chemical attributes (dry matter, starch, protein, fat, sugar, fibre, ash and predominant minerals) functional attributes (ascorbic acids, glycoalkaloids, total phenolic contents, radical scavenging activity) and processing performance (chip moisture contents, fat absorption, color and sensorial attributes) were evaluated in ten commercial varieties i.e. Agria, Atlantic, Cardinal, Chipsona, Courage, Desi, Desiree, Hermes, Lady Rosetta, and Satellite. In general Lady Rosetta followed by Hermes was the most appreciable variety regarding their physical attributes. Lady Rosetta followed by Atlantic attained maximum dry matter and starch contents. Least sugar contents were recorded in Agria and maximum fat and protein contents were quantified in Desiree. In general; functional attributes were found maximum in Desi followed by Desiree. A promising correlation was estimated between most of these parameters with distinctive correlation (R=0.903) identified between total phenolic contents and radical scavenging activity. Post processing parameters like moisture contents, fat absorption, and sensory evaluation in Lady Rosetta showed its preference over all other varieties followed by Hermes. In the second phase variety” Lady Rosetta” was evaluated under different storage conditions 1 2 (packaging, light, temperature, and anti sprouting agents) on the basis of transition in their quality attributes (reported in 1st phase) and enzymatic (polyphenol oxidase, peroxidase) activities. Potatoes were stored under different packaging materials (jute, nylon, polypropylene, cotton, low density polyethylene, medium density polyethylene, high density polyethylene) at ambient temperature (25±2oC). Results revealed that polypropylene packaging and low density polyethylene packaging were found best and maintained tubers quality attributes up to 63 days, while other packaging materials were also found effective as compare to control. Thirty days storage of tubers under different illuminations (blue, fluorescent, green, mercury, red, dark) at ambient temperature (25 ±2oC) was carried out. Potato tubers kept under dark presented minimum loss of quality parameters however green and mercury lights posed best storage performance over all other illuminations during one month. Tubers were found highly susceptible to fluorescent light with poor processing attributes were recorded in red and blue light exposures. Results under comparative temperature regimes (5, 15 and 25oC) showed maximum storage stability up to 126 days under 5oC, however associated with low enzyme activity, elevated sugars contents in tubers and poor processing performances in fried chips. Exposing tubers to different anti sprouting agents (hot water treatment, spearmint oil, clove oil, CIPC) showed that CIPC and Clove oils applications were found significant in preventing tuber sprouting at the end of 80 days storage. In general, both retained superior tuber characters with remarkable processing characters during the storage period. Tuber dormancy was ensured under both treatments till the end at ambient temperature (25 ± 2oC) storage. In the last phase integrated post harvest management of potato variety “Lady Rosetta” on the basis of best results identified in second phase ensured tuber dormancy and prolonged storage life up to 180 days with appreciable retention of tuber quality attributes and superior processing performance as compare to 100% sprouting observed in control on the 80th day of storage. Coating of potato chips with 20% aloe vera gel presented best results with reduced fat uptake along with appreciable sensorial scores.
مولانا سید شاہ رضوان اﷲ قادری مجیبی افسوس ہے کہ خانقاہ مجیبیہ پھلواری شریف پٹنہ کے سجادہ نشین مولانا سید شاہ رضوان اﷲ قادری مجیبی ۳۱؍ دسمبر ۲۰۰۳ء کو وفات پاگئے، اِنا ﷲ وَاِنا اِلیہ رَاجِعونْ۔ ابھی عمر کی جس منزل میں وہ تھے، یہ جانے کے دن نہیں ہوتے لیکن مشیت الٰہی میں کس کا دخل؟ موت کا تو وقت مقرر ہے، فَاِذَا جَآءَ اجلُھُمْ لَا یستَأخِرُونْ سَاعۃ وَّلَا یستَقْدِمُوْنَ۔[الاعراف:۳۴] خانقاہ مجیبیہ کا علمی و روحانی فیض مدت دراز سے جاری ہے، شاہ صاحب اس کی قدیم روایات اور اپنے عالی مقام اسلاف کی خصوصیات اور خوبیوں کے حامل تھے اور خود بھی ایک صاحب فیض عالم اور ذاکر و شاغل بزرگ تھے، ان کی ذات سے ہزاروں طالبین و سالکین فیض یاب ہورہے تھے مگر اب تزکیہ و اصلاح اور ارشاد کا یہ سرچشمہ بند ہوگیا۔ ان کو تقویٰ و اخلاص، صوم و صلوٰۃ کی پابندی، سادگی و درویشی اور خوش مزاجی و خوش خلقی ورثے میں ملی تھی، راقم کو دو تین بار ان کی خدمت میں حاضری اور ان کی پاکیزہ سیرت اور مطہر زندگی کے جلوے دیکھنے کا اتفاق ہوا، ہر بار نہایت خندہ پیشانی سے ملے اور لطف و کرم سے پیش آئے، اﷲ تعالیٰ ان کے درجات بلند کرے اور پس ماندگان کو صبر جمیل عطا کرے، آمین۔ (ضیاء الدین اصلاحی، فروری ۲۰۰۴ء)
In Islam the system of Judiciary halds an immense importance the judiciary after faith is counted as an important obligation amongst all other obligations and is eminent and virtous amongst all outs of worships. The virue of judiciary is mentioned at hundreds of places in the Quran and in the Ahadiths. The Progression of the system of judiciary has been hard from the begning of the prophet hood, during the Rashidun ealiphale and is promulgated till tody. Before the existence of Pakistan there were many states amongst which one was the state of Kalat. Where the Baloch Government was setup in 1530 Meer Ahmed Yar Khan was elected as the Khan of Kalat. Who at the very Beginning laid the foundation of the system of judiciary? The details about this would be discussed in the article ahead. The Government of Balochs was set up in Kalat the foundation of system of judiciary here was first of all laid by Mir Ahmed Yar Khan. First of all juges were appointed in every district.
Learning is the process of observation, exploration and discovery. Virtual Reality (VR) is one of the most popular training technologies today that introduced new methods and approaches for teaching-learning process. It offers advanced forms of interaction that enables students to find out, to explore and to build their own knowledge. The use of 3D-Virtual Learning Environments (VLEs) for educational purposes can improve a learner experience and motivation. Adaptive 3D-VLEs dynamically adapt to learners capabilities and show customized teaching mate rials which are relevant and according to the learning goals, learning style and knowledge level of an individual learner, which results in improved learning. Properly designed 3D-VLEs with adaptive capabilities increase both the effec tiveness of learning-process and interface usability. However, defining the adaptive aspect of 3D-VLEs is difficult as there is no clear strategy which modifies the con tents of the environment for a specific learner. Research on designing such systems is still in its infancy and needs attention for possible improvements. This research work focuses on the adaptive aspect of 3D-VLEs. We quantitatively measure the learning skill of a student in 3D-VLEs with the help of a mathematical function and use it an adaptation criterion for changing the contents of the environments. Using a fuzzy logic based approach, our system dynamically builds and maintains student model and delivers personalized learning content for good, average and weak students. Research shows that providing cognitive aids reduce mental load on learn ers but it also reduces active exploration which affects their performance in a non-supervised environments when these aids are no longer available. Using the proposed adaptive approach, we further extended our work and presents Adaptive Repetition as a control strategy for active exploration in 3D-VLEs which enables students to get the benefits of cognitive aids and remain actively involved in the learning and exploring process. Finally, we introduce the concept of horizontal transition inside adaptive 3D VLEs which provides an opportunity for students to get the desired knowledge according to their learning styles. The same concept is presented with detail information and more examples that facilitate the learning process and is especially designed for weak students. Based on the proposed adaptive criterion, we developed a simulated environ ment in Microsoft Visual Studio 2008 using OpenGL Library to perform experi ments and evaluate the efficiency of the proposed concepts. The analysis was based on task completion time, no of errors, test scores and student learning. We also used questionnaires to collect the data for subjective evaluations. The outcome of this research work is a student friendly framework that can be used efficiently for enhancing the learning capabilities of students in 3D-VLEs.
