برصغیر میں عربی ادب کا تحقیقی جائزہ اور اس کے اثرات

At the time of arrival of Muslim community in Sub-Continent Region and due to their settlement in the region Arabic Language has been prevailed and such as the system of its publication and learning has been commenced. Because the directives of Islam and laws are in the Arabic Language as per Quran & Sunna so that it is necessary to learn the Arabic language for the awareness of Islamic directions. So that to achieve the knowledge of Sharia inclu-ding the expertise the peoples of Sub-continent has been achieved the expertise of Arabic language, literature, knowl-edge Ilmul Saraf al-khawa, knowledge of al-ishtiaq & Ilmul Balaghta etc. Moreover it is clarify that Scholar of religious have shown their expertise so that the scholar of Arab have been convinced their expertise. The basic point of service in Arabic Language of Scholars of Sub-Continent that they do not served only to enhance the language but the cause of service was to serve themselves on religious matters and represents themselves on work hard and tried themselves to achieve the better performance of identification of Islam.  A positive result and effects have been achieved as a sun shining of Islam is remaining and its waves are enhancing all around the world such as the sun shining of Islam is remained in Arab world such as the publication of literature is also remaining in the Sub-Continent region in the actual shape and saved. Because the Islam will remain till the day of judg-ment and its representatives/workers will born till the date such as the scholars of literatures will also born and they will save the knowledge of Arabic.  They will alive till the Day of Judgment.

Kinetics of Photochemical Reactions of Thionine

Hie photochemical reduction of thionine by N-phenyl glycine, N-allylurea, N -phonylurea and thiourea in absolute me¬ thanol ms investigated. An apparatus for the irradiation of air free solutions, with known intensities of monochromatic light was constructed. Double walled glass reaction cell was deviced in which nitrogen inlet/outlet, water inlet/outlet ar¬ rangements were made. Acidities of the reaction solutions were controlled using buffer solutions. Acidities determined spec- trophotometrically using basic indicator were expressed in terms of a Hamnett acidity function. Variations of quantum ef¬ ficiencies in absolute methanol have been determined at various concentrations of thionine, reductants, and acidities. The oxy¬ gen free reaction solutions were irradiated and the react ions were followed by measuring the intensity of light transmitted. The quantum efficiency, in yellow light, for the dis¬ appearance of thionine, was found to be a function of reductant concentration, acidity and temperature. The quantum efficiency was found to be independent of the concentration of thionine. The results have been interpreted in terms of a reaction mechanism Ratios of the certain rate constants for the proposed mec banian have been evaluated. It was found that the quantum efficiency is controlled by two equilibriums between: i) triplet state of thionine with proton, and protonated triplet state of thionine, and ii) protonated triplet state of thionine with reductant, and associated complex of thionine with reductant.
