The immense proliferation of research papers in journals and conferences poses challenges for researchers wanting to access relevant scholarly papers. Recommender systems o er a solution to this research problem byltering all of the available information and delivering what is most relevant to the user. Several approaches have been proposed for research paper recommendation, variously based on metadata, content, citation analysis, collaborativeltering, etc. Approaches predicated on citation analysis, including co-citation analysis and bibliographic coupling, have proven to be signi cant. Co-citation has been analyzed at content level and the use of citation proximity analysis has shown signi cant improvement in accuracy. However, co-citation presents the relationship between two papers based on their having been mutually cited by other papers, without considering the contents of the citing papers. Bibliographic coupling, on the other hand, considers two papers as relevant if they share common references, but traditionally does not consider the citing patterns of common references in di erent logical parts of the citing papers. The improvement found in cases of co-citation when combined with content analysis, motivated us to analyze the impact of using proximity analysis of in-text citations in cases of bibliographic coupling. Therefore, in this research, three different approaches were proposed that extended bibliographic coupling by exploiting the proximity of in-text citations of bibliographically coupled articles. These approaches are: (1) DBSCAN-based bibliographic coupling, (2) centiles-based bibliographic coupling and (3) section-based bibliographic coupling. Comprehensive experiments utilizing both user study and automated evaluations were conducted to evaluate the proposed approaches. The results showed signi cant improvement over traditional bibliographic coupling and content-based research paper recommendation

شاہ فیصل شہید

فیصل، شاہ ( شہید )
کل شیء ھالک الا وجھہ
گزشتہ مہینہ شاہ فیصل کاحادثۂ شہادت موجودہ حالات میں عالم اسلام کا سب سے بڑا المیہ ہے جس کی شدت کوایک مدت تک فراموش نہ کیاجاسکے گا۔ مرحوم اس زمانہ میں عالم اسلام کی آبرو، عزت و وقار اورتمکنت تھے۔ قدرت نے انھیں سوز اورساز دونوں نعمتوں سے نوازا تھا۔کہنے کوخادم حرمین شریفین تھے لیکن درحقیقت وہ پاسبان ونگہبان حرم اسلام تھے۔ نورایمان ویقین ان کاجوہر ذاتی، تعامل بالکتاب والسنۃ ان کاآئین حقیقی، فہم وفراست اورتدبر و دوراندیشی ان کی طبیعت کے گوہر آبدار تھے۔ مرحوم کی سربراہی کی مدت گیارہ برس سے زیادہ نہیں ہے، اوریہ وہ زمانہ ہے جب کہ عالم اسلام اندرونی وبیرونی اسباب وعوامل کے باعث شدید کشمکش امید وبیم سے دوچار تھااوراس کے سرپر اضطراب وتشویش کی قیامتیں مچل رہی تھیں، لیکن شاہ فیصل کی قائدانہ بصیرت وبصارت نے وہ معجزہ نمائی کی کہ عالم ہی دوسرا ہوگیا۔ امریکہ جواس وقت دنیا کی سب سے بڑی طاقت و قوت ہے اورسیاست’’ فرنگ‘‘__جواس دور کا سب سے بڑاحربہ ہے، دونوں نے اس طرح سپرافگنی کی کہ روس اورامریکہ کے بجائے عالم کی نظریں شاہ کی جنبش مژگان وآبروپرمرتکز ہوگئیں اورامریکہ کے ٹائمز وغیرہ کوتسلیم کرنا پڑا کہ اس زمانہ کاسب سے بڑاسیاسی اورطاقتور انسان شاہ فیصل ہیں۔ یہ انھی کا حوصلہ تھا کہ عرب کی طاقت کالوہا دنیا سے منوالیا،انھوں نے عرب ممالک میں اتحاد پیدا کیا، انھیں خوداعتمادی سکھائی، عرب قومیت کی لعنت سے نجات دلا کرانھیں صراط مستقیم پر گامزن کیا۔ان کے دل میں اسلام اورمسلمانوں کادرد کوٹ کوٹ کر بھرا ہوا تھا۔ انھوں نے اربوں اورکھربوں روپیہ سے ضرورت مند عرب اوردوسرے عرب اسلامی ممالک کی بے تحاشا مدد کی، دنیا میں جہاں کہیں بھی مسلمان آباد ہیں ان پر اُن کی نگاہ رہتی اوراُن کے فوزوفلاح کی تدبیر...

Effect of storage on PHYSIO-CHEMICAL EVALUATION OF PEANUT YOGURT Effect of storage on peanut yogurt

ABSTRACT: Peanuts may be consumed in a variety of processed forms like roasted, raw and processed etc. And represent as a multimillion dollar crop worldwide with many potential dietary benefits as it contains high protein and health effective oils. Objective: The present investigation was planned to evaluate thephysio-chemical properties of peanut milk yogurt by the addition of different concentration of peanut milk (0 %, 10 %, 20 % and 30 %), skimmed milk liquid (60 %, 70 %, 80 %, and 90 %), skimmed milk powder (9 %) and sugar (1 %). Methods: The physico-chemical tests (pH, acidity, moisture, ash, fat, protein, syneresis, and viscosity) were examined after every 5 days of interval for a period of 15 days at 4 ºC. Results: The results of physico-chemical analysis revealed that pH, ash, fat, protein and viscosity decrease during storage period where as acidity, moisture and rate of syneresis increased during storage. Treatment T1 (10 % peanut milk) was comparatively best for manufacturing of peanut milk yogurt followed by T2 (20 % peanut milk + 70 % skimmed milk liquid + 9 % skimmed milk powder + 1 % sugar) while peanut milk yogurt from (30 % peanut milk + 60 % skimmed milk liquid + 9 % skimmed milk powder + 1 % sugar) had the lowest degree of firmness. Conclusions: It was noticed that correlation among fat, total solids and protein contents in peanut milk affect the extent of serum separation and pH of yogurt. The storage had significant effects on all physico-chemical parameters. Treatments had significant effect on all physico-chemical parameters

Integrated Management of Mycotoxins in Red Chilli

Red chilli (Capsicum annuum L.) is a major crop of Pakistan. Sindh contributes 85% of its production and a small town “Kunri” is one of the largest centres for red chilli production in Asia. Red chilli is a major food ingredient and is utilized for the production of essence, pungency and red color. It is an excellent source of vitamin C and has several medicinal uses. The overall production of red chilli has decreased during the years 2006-2007. One of the main reasons for this decline is mycotoxin contamination. Contamination by mycotoxins in the red chilli crop drastically reduces its quality, due to which Pakistani red chilli is unable to enter in the world market and has been banned by European Union Food Authorities, which led to the decrease in export and production. Mycotoxins are a chemically diverse group of fungal metabolites that have a wide variety of toxic effects. The most serious and toxic example are the Aflatoxins (B1, B2, G1, G2) produced by Aspergillus flavus and A. parasiticus. Aflatoxin B1 is considered a major cause of liver cancer. The present study was planned to develop an integrated approach for the management of mycotoxin contamination in red chilli. For this purpose, available germplasm was evaluated to determine the resistance level of red chilli varieties against mycoflora and production of mycotoxins. The mycoflora were isolated by employing standard techniques; associated mycotoxins were analyzed by chromatographic techniques; different antagonistic bioagents and plant diffusates were tested in-vitro for their effectiveness in managing the mycotoxins and mycotoxin producing fungi. The highly susceptible variety „Nagina‟ was subjected to crop management trials in the greenhouse. Firstly, different irrigation levels were evaluated; which have been reported to induce significant reductions in 1 2 toxins. Secondly, different species of yeast like Saccharomyces cerevisae, S. bayanus, S. postoranus and their doses were applied at flowering stage of crop. Finally, the best treatment from these individual trials was incorporated in an integrated mycotoxin management experiment. The significance of each treatment in trials was evaluated by detection and quantification of mycotoxins, estimation of yield components (fresh weight, dry weight, number of pods), nutritional profile and seed viability of produce. At this stage, the formulation of plant diffusates and bio agents with highest proficiency in the in-vitro management trial were applied to chilli pods and pre and post-application status of mycotoxins were recorded. This study provides a record of the mycoflora and mycotoxins associated with various varieties of red chilli. Most importantly, it provides the resistant/tolerant locally available red chilli cultivars (Kunri & Drooping type) which were less contaminated. In addition, the use of Saccharomyces species during pre-harvest and Lactobacillus rhamnosus at the post-harvest stage were some major findings of this study. Finally, the integration of best pre and post-harvest treatments was the most useful strategy for the management of mycotoxins in red chilli. This work provides better and more cost effective technology for farmers to produce high quality toxin free chillis which will not only increase the demand for Pakistani products in international markets but will also become the source of enhanced foreign exchange and farmer income.
