مسٹر کینیڈی
امریکہ کے پریسڈنٹ مسٹر کنیڈی کا قتل بہت بڑا بین الاقوامی حادثہ ہے، جس کا اثر پوری دنیا کی سیاست پر پڑیگا، وہ غیر معمولی صلاحیتوں کے مالک تھے، ابھی ان کی عمر ۴۶ سال کی تھی، اور ان کی مدت صدارت بھی ڈھائی سال سے زیادہ نہ تھی، اس عمر اور اس مدت میں بین الاقوامی معاملات میں انہوں نے جس تدبر اور ہوشمندی کا ثبوت دیا وہ ان کی سیاسی بصیرت اور عالی دماغی کی بین شہادت ہے، وہ مختلف رنگ و نسل کی قوموں کے درمیان مساوات، دوستانہ تعلقات اور امن کے بڑے علم بردار تھے، اور اس راہ میں ان کے بڑے کارنامے ہیں، وہ نسلی تفریق و امتیاز کے سخت خلاف تھے اور اس میں انہوں نے اپنی قوم کی بھی مخالفت کی پرواہ نہیں کی اور نیگرو اور یورپین نژاد امریکنوں کے درمیان حقوق کے مساوات کی کوشش کے جرم میں قتل کیے گئے، اس لیے ان کا قتل درحقیقت انسانیت کی راہ کی قربانی ہے، مذہبی حیثیت سے بھی وہ قابل قدر تھے، وہ راسخ العقیدہ کیتھلک تھے، پروٹسٹنٹ میں تو برائے نام مذہب رہ گیا ہے، گورومن کیتھلک کی بعض رسمیں مشرکانہ ہیں لیکن یورپ و امریکہ کی خدا بیزار اور مادہ پرست سرزمین میں مذہب انہی کے دم سے زندہ ہے۔ (شاہ معین الدین ندوی، دسمبر ۱۹۶۳ء)
This research is a conceptual paper that examines the impact of the presence of the Covid-19 vaccine on investor sentiment and the performance of the global stock market after being hit by high concerns due to the pandemic. The results showed that each stage of vaccine development received high appreciation from stock investors, especially after vaccine candidates passed clinical trials in humans. Investors' positive sentiment towards the vaccine program boosted stock market performance. However, the sentiment of this vaccine cannot stand alone, it needs government policy support to truly restore market confidence in the recovery of social and economic conditions, including the stock market. This research combines secondary data published from high-ranking journals that can be used to help develop future tests.
The industrial revolution has led to an unequal and uncontrolled distribution of the toxic substances in different compartments of the environment. A large number of researchers have offered specific solution to combat the hazardous and toxic substances. The real challenge faced today is the complex interaction of the pollutants in each compartment compelling the scientists to develop materials offering one spot solution applicable to a wide range of toxicants. The present investigation is an effort to synthesize a range of different materials having multi-dimensional potential for removing diverse pollutants with general efficacy and limited specificity. Though a number of materials fall under the same category, the Zeolites and their tailored forms offer advantages such as thermal stability, low-cost, ease of availability, and high sorption affinity. Zeolites and their functionalized hybrids have attracted interest from academic and industrial laboratories due to high catalytic and exchange properties. In the present research, Zeolite as base material is synthesized from economical precursors using hydrothermal method. Post modification for synthesis of functionalized hybrids is attempted with doping of metals (Cu, Zn, and Cu/Zn), organic moieties ((Thiophene, Dibenzothiophene, and Thiophene/ Dibenzothiophene), and combination of both into the Zeolite framework. On the basis of induced functionality the eleven hybrids of Zeolite are grouped into three categories. The purpose of preparation of hybrids is to have diverse functional groups on the surface of a single Zeolite to adsorb a variety of pollutants from environmental media. The synthesized materials are subjected to a series of characterization techniques to determine surface and bulk properties for effective adsorption. The successful incorporation of the functional groups (Thiol, CH3, and Metal-Oxygen) is indicated by FTIR, BET surface area and SEM analysis proposes that crevices and channels serve as pores for uptake of incoming pollutants. Further, EDX shows silica and alumina percentage which is involved in developing zeolite framework (internal and external linkages) for binding. The thermal stability of Zeolite (360-570°C) is assessed from TGA studies. XRD demonstrates the amorphous nature of Zeolite framework that generally decreases on functionalization. Zeolite and the functionalized hybrids are applied for the removal of Metals (Hg, As), Dyes (Methylene Blue, Methyl Orange), Polyaromatic Hydrocarbons (Benzene, Naphthalene, Phenanthrene, and Pyrene), Sulfur (Model Fuel, Commercial fuel) and Insecticide (Imidacloprid). For each application, closed batch adsorption protocol is followed. The results of adsorption experiments confirm the efficiency of synthesized hybrids as adsorbents for the removal of a number of pollutants. Generally, mercury showed better removal than arsenic on the adsorbents. Moreover all Zeolite based hybrids testifies the fitness of pseudo-second order kinetics & Langmuir and Freundlich isotherms for the removal of mercury and arsenic. The hybrids depict higher removal capacity for methylene blue in comparison to methyl orange. Moreover Zeolites shows good removal potential for sulphur, Imidacloprid and polyaromatic as well.
