The Large Hadron Collider (LHC) is a top-quark factory, the large number of the topquarks are produced which can be used to measure various properties of the top-quark with a much higher precision. This thesis describes the single-top-quark t-channel inclusive and differential cross-section measurements in a proton-proton collisions at a center-of-mass energy of 8 TeV using lepton+jets in the final state. The results for the inclusive cross-section and the differential cross-section measurements are based on a data set which corresponds to an integrated luminosity of 19.7 fb?1 recorded with the CMS detector at the LHC. The measured inclusive production cross-section of the t-channel single-top-quark is: st?ch. = 83.6 2.3 (stat.) 7.4 (syst.) pb. The measured single t and t production cross-sections in the t-channel is: st?ch.(t) = 53.8 1.5 (stat.) 4.4 (syst.) pb, st?ch.(t) = 27.6 1.3 (stat.) 3.7 (syst.) pb. The measured cross-section ratio, top-quark(t) and the anti-top-quark(t), when separated on the basis of charged lepton at p s = 8 TeV is: Rt?ch. = st?ch.(t)/st?ch.(t) = 1.95 0.10 (stat.) 0.19 (syst.), and the measurement of CKM matrix element, j fLvVtbj = 0.979 0.045 (exp.) 0.016 (theo.), comes out to be in good agreement with the standard model predictions. The single-topquark differential cross-section measurements as a function of the top-quark pT and jyj are performed. The differential cross-section measurements are essential for the comparison of the QCD predictions in the standard model. The measured normalized differential cross-sections come out to be in a remarkable agreement with the various theoretical predictions.

ڈ اکٹر محمد معظم جیراج پوری

آہ! ڈاکٹر محمد معظم جیراجپوری
دارالمصنفین کی مجلس عاملہ و انتظامیہ کے رکن ڈاکٹر معظم جیراجپوری بھی ۱۴؍ جولائی کو دہلی میں انتقال کرگئے اور وہیں جامعہ ملیہ اسلامیہ کے قبرستان میں تدفین ہوئی۔ ان کا وطن اعظم گڑھ کا معروف گاؤں جیراج پور ہے، یہیں ۱۹۲۰؁ء میں وہ پیدا ہوئے تھے، ان کا خاندان علمی، تعلیمی، اور دینی حیثیت سے ممتاز تھا، ان کے دادا مولانا سلامت اﷲ جیراجپوری مولانا سید نذیر حسین محدث دہلوی کے ارشد تلامذہ میں تھے، وہ نواب صدیق حسن خاں کی دعوت پر بھوپال تشریف لے گئے اور ریاست کے مدارس کے اہتمام کی خدمت پر مامور ہوئے، وہ جمعیۃ اہل حدیث کے سرخیل تھے ان کے اثر سے اعظم گڑھ میں اس مسلک کی ترویج و اشاعت ہوئی۔ ڈاکٹر محمد معظم کے والد مولانا حافظ محمد اسلم جیراجپوری انہی کے لایق فرزند اور ملک کے مشہور عالم و مصنف تھے جو مدۃالعمر جامعہ ملیہ اسلامیہ میں تاریخ اسلام و دینیات کے استاد رہے، ڈاکٹر محمد معظم کی تعلیم بھی جامعہ میں ہوئی۔ اس کے بعد انہوں نے طب کی تحصیل کی۔
تعلیم مکمل کرنے کے بعد انہوں نے اعظم گڑھ میں اپنا مطب کھولا۔ اپنی اصول پسندی، محنت، پیشہ میں یکسوئی و انہماک اور مریضوں کے علاج میں نہایت دلسوزی کی وجہ سے بہت جلد کامیابی نے ان کے قدم چومے اور وہ پورے ضلع میں ایک اچھے معالج کی حیثیت سے مشہور ہوگئے، صبح و شام کو مریضوں کا تانتا لگا رہتا تھا۔
علم، ادب اور شعر و سخن سے دلچسپی کی بنا پر شام کے وقت ان کے مطب میں ادیب و شاعر، شبلی کالج کے اساتذہ اور دارالمصنفین کے رفقاء کی نشست ہوا کرتی تھی، بڑے باغ و بہار آدمی تھے اپنی دلچسپ اور پُرلطف باتوں سے مجلس کو زعفران زار بنادیتے تھے، خود بھی شعر کہتے...

مروّجہ انعامی اسکیمیں اور ان کی شرعی حیثیت

Islam is a complete code of life. It provides injunctions for every field of life. In economics it not only provides us details in finance and trade but also provides us information about "Halal & Haram". Needless to emphasize that economy plays an important role in the development of nation and financial matters cannot be ignored if development is a target. According to Islamic teachings all earnings must be lawful. Generally, new ways are being adopted to increase and generate wealth. Islam encourages to get more wealth and profit but no illegal means should be adopted for that. All kinds of fraud and unfair means while doing business must be avoided. Islam lays stress on using lawful and valid means in all economic activities. Scholars of Sub-continent have different opinions about the prevailing prize money schemes. Some scholars consider them lawful regarding some aspects but majority term them unlawful.

A Critical Analysis of Innovative Approaches Applied in Teacher Education in Pakistan

Education is the basic need of every human being that is imparted by the teachers. A teacher needs up to date education which enables him to transfer his knowledge to the new generation appropriately. In order to increase teachers’ professional competencies and effectiveness in implementing the teaching strategies, teachers should always be given training of innovative approaches cropping in the educational system. The aim of present study was to critically analyze the innovative approaches applied in teacher education in Pakistan. The objectives of the study were to find the innovative approaches of teacher education in Pakistan and extension of innovative approaches those are employed in teacher education in Pakistan. This study was also focused on analysing male and female prospective teacher attitude towards the use of innovative approaches in pre-service teacher education in Pakistan. It was a descriptive study and only GCETs of Punjab province were selected for study as other provinces of Pakistan are providing the same education to teachers like GECTs of Punjab. 10 The population of the study consisted of 1535 B.Ed level prospective teachers and 231 teacher educators of formal education in the 33 GCETs of the Punjab. Purposive sampling technique was used and 11 GCETs (33 percent) were selected. The sample of prospective teachers was 941 and teacher educators were 86. The data was collected with the help of questionnaires, administrated to prospective teachers and teachers. Percentage of recovered questionnaire responses was 82 percent of prospective teachers and 83 percent of the teacher educators. The data collected were analyzed by using percentage, mean scores, t-test and one way ANOVA. The main findings about teacher educators were that there were 71 teacher educators (46 male and 25 female). There was no significant difference between male and female teacher educators regarding use of CAI, Multimedia, Micro-Teaching technique and other training aids at GCETs. The more professional teaching experience at B.Ed level of teacher educators had increased the efficiency of prospective teachers like aware about of innovative approaches, usage of training aids and dealing with the problems of innovative approaches. There was significant difference between male and female prospective teachers about the use of CAI and multimedia. The hostel resident’s prospective teachers were using teaching aids more as compared to the day scholars. The main conclusion about teacher educators indicated that despite teacher educators had different academic and professional qualification, total teaching experience and total professional teaching experience, all had similar opinion regarding use of different innovative approaches in teachers’ education in Pakistan. On the other hand, conclusion about prospective teachers projected that they were 11 of the same opinion regarding the use of innovative approaches (CAI, Multimedia and Micro-Teaching technique) and its factors in teachers’ education in Pakistan. The comparative conclusion of teacher educators and prospective teachers about use of CAI indicated that prospective teachers were more interested in using the computer assisted instruction as compared to their respective class teacher educators. The main recommendations about the use of innovative approaches, it was suggested that Directorate of staff development and provincial institute of teachers education of all provinces may instruct their respective Govt college for elementary teachers to use the innovative approaches during teaching learning process and Directorate of staff development may pursue the funding agencies to provide the requisite funds to their respective Govt. college for elementary teachers to use the other innovative approaches like teleconferences and co-operative learning process.
