شری مشرو والا
افسوس ہے کہ گزشتہ مہینہ گاندھی جی کے مشہور چیلے شری مشرو والا نے انتقال کیا، وہ ہریجن کے اڈیٹر اور گاندھی جی کے مشن کے سچے حامل و مبلغ تھے اور اس زمانہ میں جب کہ کانگریس اپنے اصولوں سے عملاً بالکل ہٹ گئی ہے اور کانگریسیوں کی اکثریت اقتدار کی ہوس، ذاتی اغراض اور فرقہ پرستی میں مبتلا ہے اور فرقہ پرستوں اور خود غرضوں کی قوت اتنی بڑھ گئی ہے کہ سچے کانگریسی بھی مشکل سے ان کے مقابلہ میں زبان کھولنے کی جرأت کرسکتے ہیں، مشرووالاجی اپنے اصولوں پر قائم تھے اور آخر دم تک نہایت دلیری کے ساتھ گانگریس کی غلط روی پر تنقید اور گاندھی جی کے اصولوں کی تبلیغ و اشاعت کا فرض انجام دیتے رہے انھوں نے ان کی تعلیمات پر متعدد کتابیں لکھی ہیں، اس خود غرضی اور فرقہ پرستی کے دور میں ایسے مخلص اور سچے کانگریسی کا اٹھ جانا ایک ناقابل تلافی نقصان ہے، ان کی موت سے متحدہ قومیت کا ایک بڑا ستون گرگیا، جس کی جگہ مدتوں نہ بھر سکے گی۔ (شاہ معین الدین ندوی، اکتوبر ۱۹۵۲ء)
To serve humanity and nation leadership is a noble and glorious position. Sensible, talented, honest and true leadership not only works honestly with dedication and commitment in solving internal and external challenges, but also plays a key role in the development of peace and prosperity in society. Due to the lack of spirit and training of the people, especially of the younger generation, these incompetent leaders succeed in befooling many people and it transferred from generation to generation, in order to change this scenario, education and training of the young generation is urgently needed. True spirit of leadershipcan be promoted by creating sincerity, awareness in students in the light of Islamic teachings. This article focuses on the Islamic attributes of leadership through which a person can have opportunities to transform social system by bringing reforms and development in social system to perform the duties by guiding and governing people with the noble aim to serve humanity according to modern requirements in the light of the teachings of holy Prophet.
The cross section measurements of a single top quark in association with a Z boson using proton-proton collision data collected by CMS experiment are reported in this thesis. The measurements are performed by analyzing integrated luminosities of 19.7 fb1 and 35.9 fb1 which were collected at 8 TeV and 13 TeV. The measurement are performed within the standard model framework where top quark is produced via the t-channel process. The measurements in three lepton final state, where the W boson from the top quark and the Z boson decay into either electrons or muons, resulting in four possible lepton combinations namely eee, eeµ, µµe, µµµ, are discussed. The final state electrons or muons can also come from from leptonic ⌧ decays, as they are not specifically excluded. The main sources of background to the tZq process are t¯ t production, diboson production (WZ, ZZ), ttV (V = W or Z) and Drell-Yan (DY) production. A simple cut and count technique is used for the cross section measurement. For theps = 8 TeV measurement, a one bin likelihood fit is performed to event yields in each four lepton channels and to the combined channel. The cross section for the combined channel is measured to be (t`+`q) = 18+11 9 (stat)+4 4(syst) fb, where ` stands for electrons, muons and ⌧ leptons, with an observed (expected) significance of 1.81 (0.81) standard deviations. The measured value is compatible with the NLO standard model prediction of 8.2 fb with a theoretical uncertainty of less than 10%. For the second cross section measurement at 13TeV, the signal is extracted by performing a simultaneous binned likelihood fit to yields in the signal and the background enriched control regions. The cross section for the combined channel is measured to be (t`+`q) = 156+47 42(stat)+40 34(syst) fb, which is compatible with the NLO standard model prediction of 94.2 ± 3.1 fb. The measurement is found to be in agreement with the standard model with an observed (expected) significance of 2.81(1.95) standard deviations.
