فکر اقبال کے تناظر میں تہذیبی تصادم

A thorough critical analysis of human history highlights that the clash of civilizations centered on themes of conflict, war, and struggle. Historical experts use the word encounter to interpret or explain these relations among civilizations. Trade played a vital role in flourishing these ties, however, conflict and encounter have also been a part of almost all the phases or eras of human history. Developing nations have always looked up to the western world as a role model of economic and military progression, but this philosophy has also resulted in the escalation of tensions among these nations. World peace faces daunting challenges and is one of the most talked-about human concerns in the present times. Islam is currently being challenged by the western world in terms of the right interpretation of religious teachings and the true message of the Holy Quran and Sunnah. Islam is still struggling to make its mark in the present world order, particularly after the 9/11 incident which painted Muslims as terrorists and fundamentalists. It is quite evident that the world is divided into factions or groups, where one group is the torchbearer of Islam and religious teachings, while the second group endorses western ideals or secularism. According to Samuel Huntington, it won’t be wrong to say that the next ideological challenge that the world faces after the ultimate demise of the Soviet Union is Islam and the prospective clash between the East and the West in the 21st century will be the most discussed topic. The present-day relationship between the East and the West is based upon rivalry. This conflict is not a new area of research and is centuries old. The only solution to this problem is to promote global peace and harmony and facilitate dialogue among nations. This would help in creating a social system that can center on values, harmony, peace, and love. Also, Iqbal’s philosophy can act as a guiding stone and can help in resolving this crisis. Iqbal’s universal social reconstruction theory highlights how different civilizations can live together and can facilitate constructive dialogue to improve civilizational ties. This article aims to incorporate the teachings of Iqbal, especially the universal social reconstruction theory to propose solutions for inter-civilizational clashes. This article aims to use the teachings of Iqbal as a beacon of light to promote constructive dialogue and peaceful coexistence among the two dominant sides of the world, resultantly leading in much prosperous and peaceful world order. 

Synthesis, Characterization and Modification of Gum Arabic Microgels for Biomedical and Environmental Applications

In this study, Gum Arabic (GA) microgels were successfully synthesized via reverse micellization method with a high yield (78±5.0%) in 5-100 μm size range using divinyl sulfone (DVS) as a crosslinker. The as synthesized GA microgels show 22.8±3.5% biodegradability property at stomach condition (pH 1) in 20 days, whereas no degradation was observed at pH 7.4 and pH 9 conditions at 37 oC. By using diethylenetriamine (DETA) and taurine (TA) as chemical modifying agents, GA microgels were chemically modified as GA-DETA and GA-TA microgels. Remarkably, GA-DETA and GA-TA microgels show zeta potential values of 5.23±4.07 and -24.85±1.33 mV in comparison to GA microgels which give -27.31±4.20 mV overall surface charge. Moreover, blood compatibility of GA, GA-TA, and GA-DETA microgels was tested via in vitro protein adsorption, % hemolysis ratio and blood clotting index. Interestingly, GA based microgels were hemocompatible with % hemolysis ratio between 0.23 and 2.05; and the GA microgels were found highly compatible with a blood clotting index of 81±40. The biocompatibility of GA, GA-DETA and GA-TA microgels against L929 fibroblast cells also indicate 84.4%, 89.1% and 67.0% cell viability respectively at 25.0 μg/mL concentration; suggesting a great deal of potential in vivo biomedical applications up to this concentration. In addition, 5 and 10 mg/mL minimum inhibition concentration (MIC) of protonated GA-DETA microgels (GA-DETA-HCl) was determined against E. coli and S. aureus respectively. The bare and GA-TA microgels present good loading capability of 160 and 57 mg.g-1 for phenylephrine (PHP) whereas, in case of Trimethoprim(TMP), GA-DETA and GA-TA microgels show a relatively higher loading capacity of 80 and 52 mg.g-1 respectively. Contrarily, 39.27 ±1.20, 18.40 ±3.130 and 3.10 ±1.140 mg.g-1 release of PHP was observed in case of GA, GA-TA and GA-DETA microgels respectively to the BPS medium in 8 Hrs. Likewise, GA and GA-TA microgels exhibits upto 4.5 ±3.32 and 9.80 ±4.10 mg.g-1 release respectively and an unexpectedly low release amount of 3.3 ±1.94 mg.g-1 from GA-DETA microgels was monitored in case of TMP. Besides, Zeta potential measurements in this study suggest that GA-DETA microgels denote a positively charged surface in DI water. Due to this fact, GA-DETA microgels were used as micro reactor in removal study of some negatively charged pollutants such as; chromate(Cr(III)), dichromate(Cr(VI)), arsenate(As(V)), methyl orange(MO), eosin Y(EY) and Congo red(CR) from aqueous media. Thus, 0.05 g feed of GA-DETA microgels show upto 69.80, 99.30 %, 40.0 %, 91.0%, 84.10 % and 73.0 % removal capability for As(V), Cr(VI), Cr(III), MO, EY and CR respectively in 2 Hrs. mixing time. Moreover, kinetic models such as; the Langmuir, the Fruendlich and modified Fruendlich isotherms were applied to the obtained adsorption data and it was concluded that modified Fruendlich model exhibits relatively practical fit for almost all pollutants giving R2 value nearer to unity. Moreover, maximum adsorption capacity (Qm) was determined for all the six pollutants with the numerical values of 217, 256, 271, 143, 130 and 116 mg.g-1 for As (V) Cr(III), Cr(VI), MO, EY and CR respectively. Further, it was observed that the modified Fruendlich isotherm give inclusively best fit for all pollutants showing R2 values of 0.9962, 0.9926, 0.9972, 0.9988, 0.9988 and 0.980 in case of adsorption As(V), Cr(VI), Cr(III), MO, EY and CR respectively.
