ان سطروں کے لکھتے وقت پروفیسر محمد مجیب، سابق وائس چانسلر جامعہ ملیہ دہلی کے انتقال ِ پر ملال کی خبر ملی، ان کی وفات ایک ایثارپسند محب وطن ، ایک بہت ہی قابلِ قدر مصنف، اردو زبان و ادب کے ایک بہت ہی لائق عزت اور جانثار اہلِ قلم، جامعہ ملیہ کے ایک بہت ہی شفیق اور محبوب وائس چانسلر، ایک بہت اچھے انسان ، علم دوست و علم پرور کی رحلت ہے، سرِ دست ان کے لیے دعا ہے کہ اﷲ تبارک و تعالیٰ ان کو اپنی بے پایاں رحمتوں اوربرکتوں سے سرفراز فرمائے۔ آمین۔ (صباح الدین عبدالرحمن، فروری ۱۹۸۵ء)
Abstract The purpose of this study is to assess the potential of social media platforms to build a successful marketing campaign for the private health-care industry. This will be accomplished by studying the current trends, audiences, and marketing tactics that are applied to these channels. In addition, the research will make a contribution to this understanding by investigating the efficacy of various types of marketing strategies that are used in the private health-care industry, such as influencer marketing, content marketing, and social media advertising, and how these strategies can be leveraged to create marketing strategies that are more effective. This research project will also focus on identifying any bottlenecks that could be hindering the utilisation of these channels and providing solutions to improve their effectiveness in the marketing mix. This will be done as part of the overall goal of improving the effectiveness of the marketing mix. At the end of the day, the purpose of this research is to develop an understanding of how social media channels can be utilised successfully as an important instrument in marketing for the health-care industry.
In this dissertation, we investigate the properties (spectrum, radiative widths and strong decay widths) of open-bottom (B,Bs and Bc) mesons. We use the non-relativistic quark potential model to calculate the masses and wave functions of the mesons. We numerically solve the radial Schr¨odinger equation by using the shooting method to find energy eigenvalues. The radiative transitions are evaluated using the Coulomb plus linear plus smeared hyperfine wave functions. We predict strong decay amplitudes by assuming simple harmonic oscillator(SHO)wavefunctionsin themodified 3P0 model. Thesimpleharmonic oscillator parameter β for different states of mesons are obtained by fitting the SHO wave function to the corresponding quark model wave function. The total decay widths of different states of open-bottommesonsarepredictedbyincludingtheradiativeandstrongwidths. Thesetotal widths are further used to calculate the branching ratios of each decay channel for a specificinitialstateofopen-bottommesons. Thetheoreticallypredictedmassesandtotaldecay widthsarecomparedtoexperimentwherepossibleandusedtomakeassignmentsfortherecentlydiscoveredstatesofopen-bottommesons. Thepredictedpropertiesofdifferentstates of open-bottom mesons can be helpful for future experimental searches and also to test our theoretical understanding against experimental measurements once they are available.
