دور جدید میں میڈیا کی ضرورت و اہمیت اور حقیقت احوال

This article highlights the role of media in the contemporary world. Man since his birth had bestowed with quest to enfold the encompassing surroundings. In addition, due to his very nature, it is almost impossible for him to keep himself indifferent from environment. With the process of time, his primitive means of communication enhanced to the level that is playing a vital role in the current globalized social set up. Consequently, string of communication has been expended and manifested in print, electronic and social media. Media can play a very constructive, positive and meaningful role in accordance with the parameters laid down in Islam. But at the same time, it has a negative edge that can put human social set up in chaos and destruction. Current situation is that media specially western media is plaing a very undesirable role that is not only detrimental for the world as a whole, but specifically for the Muslim World. Greater responsibility lies on the shoulders of media to play his positive and apostolic role. In the article, the writer highlights the incredible role of media for establishment of interfaith harmony and peace in human society. He stresses that man is in nuclear era, the situation is very tense and little mis-happening can destroy the whole world.

Synthesis and Applications of Reactive Triazine Based Uv Protectors for Textile

Human body is very delicate towards harsh environmental variations. High energy UV radiations intentionally or unintentionally interact with our skin and eyes, causing some acute effect such as, photokeratitis, skin aging and also some chronic effects like melanoma skin cancer and DNA damage. Clothing is an important precautionary measure to combat with these damages, but low weight and high porosity of cotton fabric make it unfit for protection against UV rays. Hence, to improve the protection factor of white cotton fabric, computational approach was utilized to search the effective UV absorbers for cotton fabric. The Density Functional Theory (DFT) theory with three functionals was utilized to study the design molecules and results indicated that all the five design molecules (1-5) absorbed inthe UV region of the solar spectrum. These deigned molecules were synthesized via a condensation reaction and their structure confirmation attained through UV/Vis., FTIR and ESI-MS analysis. The theoretically calculated λmax and experimental λmax of all the five UV absorbers were in close agreement. The cottonfabric was treated with designed and synthesized UV absorbers via the exhaust method of dying and its processing conditions optimized by adapting a statistical design “central composite rotatable design” of response surface methodology. The outcomes directed that all the synthesized molecules showed 65-78 % exhaustion and 62-80 % fixation at the acquired optimized conditions. Maximum exhaustion with cotton fabric was presented by 1 and minimum shown by 5. The protection factor of the treated cotton fabric was assessed and results directed that the treated fabric with 1-4 fells in the very good Ultraviolet Protection Factor (UPF) range at 3 % concentration while fabric treated with 5 fells in good range. The UPF increased as follows: 5 <4 < 2<3<1. Whiteness index test results revealed that all the synthesized molecules did not decrease the whiteness of the fabric as much at 3 % concentration, but after exposition to light fastness testing decreased its whiteness little bit as compared to standard. Washing test results indicated that UPF of treated fabric decreased after washing process, with UV absorbers (1-4), it remained in the very good range of UPF after ten washings. While the 5 showed more reduction in UPF value after washing. Degradation studies revealed that synthesized molecules were degradable by safer advance oxidation process technology. Current study opened a new prospect for search of such molecules having more persistent nature after laundry action.
