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.

مولوی مجید حسن

مولوی مجید حسن
افسوس ہے پچھلے دنوں مولوی مجید حسن صاحب مالک اخبا ر مدینہ بجنور کا انتقال ہوگیا۔مرحوم نے اپنے اخبار کے ذریعہ ملک وملّت کی جوعظیم اورطویل خدمات انجام دی ہیں اُن کوہندوستانی صحافت کی تاریخ کاکوئی طالبِ علم نظر انداز نہیں کرسکتا۔ اُن کی پوری زندگی جدوجہد اورمحنت ومشقت کی تفسیر تھی اوراس اعتبارسے وہ آج کل کے نوجوانوں کے لیے ایک لائقِ تقلید نمونہ تھے۔علمائے دیوبند کے بڑے گرویدہ اورنہایت مخیر وسیر چشم انسان تھے، اﷲ تعالیٰ اُن کی قبر ٹھنڈی رکھے۔ [جنوری ۱۹۶۷ء]

 

حروف مقطعات کے حوالے سے مستشرق نولڈ یکے اور آٹو لوتھ کی آراء کا تجزیاتی مطالعہ

Mystical letters are among the miracles of Quran. These mystical letters are present at the start of Quranic Surah’s (Chapters). These are among the mutashabihat (Analogies) of Quran. Muslim scholars tried to define their meanings. Like other aspects of Quran and Hadith orientalists talk about mystical letters of the Quran. This article analyses the theories of Noldeke and Otto Loth regarding mysterious letters of Quran. What are their views about mystical letters of the Quran? Are their views according to the Islamic point of view of mystical letters? What are the deviations and differences as compared to traditional Islamic point of view of mystical letters? This research has been analytical by nature, both qualitative and analytical methods have been implemented.  Analyses of the views of both of the scholars in the light of traditional Islamic concept of mystical letters, shows that Orientalists including Noldeke and Otto Loth thought that mystical letters are not the part of revelation. According to them these are the names of the sources from which different chapters of the Quran had been taken during its compilation. These are on the same pattern as mystical letters are present in the Jewish books. Holy Prophet had copied them. The present study argues that Quran being the book of Lord is unchanged and mystical letters are a part of it. It is further highlighted that even some orientalists argue that the opinion of Noldeke and Otto Loth is not correct.

The Potential of Breeding Gossypium Hirsutum L. for Salinity Tolerance

Salinity is an abiotic stress that can significantly reduce the crop productivity. The primary purpose of the research was to explore the breeding potential of cotton for salinity tolerance. For this purpose, 50 cotton genotypes were grown at control, 10 dS m-1 and 15 dS m-1 salt stress conditions at seedlings stage. Variations were observed for all the genotypes for chlorophyll contents, root and shoot length, fresh shoot and root weight, dry root and shoot weight, Na+, K+ and K+/Na+. The genotypic and phenotypic coefficient of variance was moderate to high, heritability and genetic advance was also high, which indicated that genotypes can be improved for salinity tolerance at seedlings stage through selection. The genotypes that performed better for the characters having high heritability were selected as tolerant genotypes whereas the genotypes that performed poor for characters were considered salt sensitive. NIAB-824, FH-312, FH-118, MNH-992, CIM-612 and KEHKSHAN were found salt tolerant and SB-149, BS-80 and FH-114 were found salt sensitive genotypes. The Line × Tester mating design was used to find out the genetic components for yield (Plant height, Number of bolls, boll weight and seed cotton yield), fiber traits (fiber fineness, fiber strength, fiber length and ginning out turn), ionic traits (Na+, K+ and K+/Na+) and physiological traits (H2O2, SOD, POD, CAT and TSP) at control, 10 dSm-1 and 15 dSm-1 salt stress conditions. Analysis of variance indicated that there were significant differences among genotypes. The salt stress caused the reduction in all traits except Na+, ginning out turn percentage, H2O2 and SOD. Non- additive gene action was found for yield, fiber, ionic and physiological traits except Na+ ions which indicated the additive gene action. Proportional contribution to total variance for all the traits was maximally contributed by the lines whereas tester’s contribution was less. Among lines, KEHKSHAN was the best general combiner for plant height, number of bolls and seed cotton yield under control, 10 dSm-1 and 15 dSm-1 and FH-312 was best general combiner for fiber fineness, fiber length, fiber strength, ginning out turn percentage and catalase under control, 10 dSm-1 and 15 dSm-1 salt stress and FH-118 had highest GCA effects for K+ concentration, SOD and TSP under control and salt stress. Among testers FH-114 was best general combiner for most of the traits. SB-149 had positive significant GCA effects for fiber fineness, fiber length, fiber strength, POD and catalase under control and salt stress. KEHKSHAN×FH-114 had positive and significant specific combining ability effects for most of the traits and hybrid KEHKSHAN × FH-114 also indicated highly significant mid-parent and better parent heterosis for most of the studied traits. The selected hybrid can be utilized in the future breeding programs against salt stress.
