مولانا یعقوب مجددی بھوپالی
افسوس ہے کہ گذشتہ مہینے حضرت مولانا محمد یعقوب صاحب مجدوی بھوپالی نے انتقال فرمایا، موصوف کو حضرت مجدد الف ثانی ؒ سے نسبی اور خاندانی تعلق بھی تھا، وہ اس دور کے عارف کامل اور نامور شیخ تھے، ان کی خانقاہ ارشاد و ہدایت کا مرکز تھی اور اس سے بڑا فیض پہنچا، راقم کو بھی ان کی خدمت میں حاضری اور کئی مجلسوں میں شرکت کی سعادت حاصل ہوئی معلوم ہوتا تھا علم و عرفان کا چشمہ ابل رہا ہے اور دلوں کی کھیتیاں سیراب ہورہی ہیں، میری حاضری کے وقت حضرت کی عمر اسّی (۸۰) سال کے قریب رہی ہوگی، خلقتہً بھی نحیف تھے، لیکن روحانی قوت کا یہ حال تھا کہ گھنٹوں پورے جوش کے ساتھ تقریر و ملفوظات کا سلسلہ جاری رہتا تھا اور یہ روزانہ کامعمول تھا، آپ کے ملفوظات و مواعظ علم و عرفان کا گنجینہ ہیں، جہاں تک معلوم ہے ان کو قلم بند کرنے کا اہتمام نہیں کیا گیا، مولانا علی میاں نے کچھ مجلسوں کے ملفوظات قلم بند کئے تھے، جو الفرقان میں شائع ہوچکے ہیں، اگر تمام ملفوظات و مواعظ قلم بند ہوکر شائع ہوگئے ہوتے تو علم و عرفان کا یہ گنجینہ ہمیشہ کے لیے محفوظ ہو جاتا، ان کی وفات سے ارشاد و ہدایت کی ایک نورانی شمع گل ہوگئی، اﷲ تعالیٰ ان کے مدارج بلند فرمائے۔ (شاہ معین الدین ندوی، جون ۱۹۷۰ء)
Horoscopes are considered as one of the important content items in the mass media. Many people perceive and believe that these Zodiac signs have an impact on their lives. That is why they check these signs on different media regularly. The purpose of this study was to determine the perception of Sindh University students about horoscope. A cross-sectional survey was conducted from 100 students of Sindh University through a close-ended questionnaire. The results concluded that girls are more interested in horoscope than boys. The sources for horoscope prediction were mainly newspapers among the Sindh University students. The students reported that they read horoscope daily to skip the pressure and try to satisfy their minds. This research is limited to the University of Sindh students. In the future, the researchers should conduct a large-scale study with a more significant population to determine the perception of the public about horoscopes.
Modifications to the surface, structural and mechanical properties of brass have been investigated by using three different kinds of radiation sources. The first radiation source was laser, second one was laser induced plasma ions and the third one was Pelletron accelerator. Brass targets were exposed to various laser pulses ranging from 1200 to 3000 of excimer laser (248 nm, 20 ns, 120mJ and 30 Hz) at constant fluence of 6.4 J/cm2 in oxygen atmosphere (100 Torr). In order to explore the ion induced modification in properties of brass, ions were generated by two different ion sources. The laser induced plasma was employed as a first ion source for the generation of Ni, Si and C ions. Excimer laser (248 nm, 20 ns, 120mJ and 30 Hz) was used for the generation of Ni, Si and C plasma. In order to estimate ion flux and energies, Thomson parabola technique was employed. By using this technique, magnetic field of strength 80 mT was applied on the plasma plume to give appropriate trajectory to generated ions. These ions were detected by solid state nuclear track detector (CR39). In response to stepwise increase in number of laser pulses from 3000 to 12000, the Ni ion flux varies from 60 × 1013 to 84 × 1016 5 ions/cm2 with constant energy of 138 KeV. Similarly Si ion flux varies from 45 × 1012 to 75 × 1015 ions/cm2 with constant energy of 289 KeV. The flux of C ions flux changes from 32 × 1011 to 72 × 1014 ions/cm2 with constant energy of 678 KeV. The second source of ion generation is Pelletron accelerator. Brass targets were bombarded by Ni and C ions of energy 2MeV for various ions flux ranging from 56×1012 to 26×1013 ions/cm2. Scanning Electron Microscope (SEM) and X-Ray Diffractometer (XRD) were used to analyze the surface morphology and crystallographic structure of irradiated brass respectively. Universal Testing Machine (UTM) and Vickers Hardness Tester (VHT) were employed to explore Yield Stress (YS), Ultimate Tensile Strength (UTS) and mirohardness of ion irradiated brass targets. SEM analysis reveals the formation of micro/nano sized cavities, bumps, cones and wave-like ridges with non-uniform shape and density distribution after laser irradiations. Whereas, ion irradiation causes the formation and growth of nano/micro sized cavities, pores, pits, voids and cracks for lower and moderate ion flux (in all cases). At maximum ion flux the granular morphology (in case of brass irradiated by laser induced Ni and Si ions) and dendritic morphology (in the case of brass irradiated by laser induced plasma and Pelletron accelerator C ions) are observed. XRD analysis reveals that no new phases are identified in case of laser irradiated brass. However new phases of CuZnNi (200), CuSi (311) and ZnC (0012) are identified in the brass substrate after laser induced Ni, Si and C ions irradiation respectively. Whereas, no new phases are formed in case of Ni and C ion irradiation obtained by Pelletron accelerator. The variation in peak intensity, crystallite size, dislocation line density and induced stresses along with angular shifting is observed in all cases of laser and ion irradiations. Significant variations in mechanical properties of brass are observed after laser and ion irradiations. The changes in mechanical properties of an irradiated brass are well correlated with surface and crystallographical modifications and are attributed to generation, augmentation, recombination and annihilation of the ion induced defects. The laser and ion induced surface, structural and mechanical modifications of brass are significantly influenced by nature, energy and flux of radiations.
