Hardcover. Condizione: New. Sanskrit underwent drastic changes in status and function in India during the medieval period, which was characterised by the growth and development of vernacular languages and far-reaching political upheavals in the sub-continent. Its exclusive stature as the medium of India's imagination and intellectual pursuits came to be challenged with the advent of different languages and discourses in other parts of the country. The ages between the 12th and 17th centuries witnessed the reworking of tradition in the classical framework and in regional cultures with exciting inputs and additions that succeeded in making India's past an organic force, having contemporary relevance and engagement. This volume is the results of a Three-day International Conference on "Sanskrit in Medieval India; Retrieving Lost Traditions" organised jointly by Research Forum Sahitya (RFS) with the Department of Sanskrit Sahitya.

Paperback. Condizione: new. Paperback. The world without water is unimaginable and the demand for clean water is increasing rapidly for the survival of all living being. Adequate access to potable water is questionable for every one out of six people living today. So, the present work focus more on treatment of organic and industrial toxic pollutant contaminated water through photocatalysis. Co-precipitation based synthesized tin oxide (SnO2) nanoparticles preferred as catalyst to conduct photodegradation experiment. The crystallographic structure and cell parameters were calculated from XRD data. Tetragonal, rutile structure having calculated cell parameter a=b=4.735 nm and c=3.185 nm. As per the Scherer formula, the average crystalline size found to be 11.40 nm. Thermogravimetric study carried out for the precipitate before calcination to understand the thermo-chemical reactions happening during calcination. Finally, the photocatalytic activity was conducted against standard dye, methylene blue. The optimal concentration of 10-4M methylene blue solution found degraded gradually with help of SnO2 photocatalyst under UV irradiation. The absorption maximum was recorded for different interval of UV-irradiation. This item is printed on demand.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The single crystals of 2 wt% ADP doped K2SO4 crystal was synthesized and white coloured good optical quality single crystals were grown deionized water as solvent by slow evaporation solution growth technique at room temperature. From the single crystal XRD, the doped K2SO4 crystal belongs to orthorhombic system. From the powder XRD, appearance of sharp and well defined Bragg's peaks confirmed the crystalline nature of the grown crystal. T The doped K2SO4 crystal is active in the UV-Vis region and it has good transparency of about 70% with lower cut-off wavelength 390 nm. The band gap of the crystal is found to be 4.6 eV and the estimated refractive index is found to be 1.37 at 532 nm. From the microhardness, the hardness value found is to be n = 3.1, that the crystal belongs to soft material category. The SHG efficiency of doped K2SO4 is 0.457 times greater than that of KDP. It is found that the conversion efficiency of the doped crystal is greater than pure K2SO4. 76 pp. Englisch.

O acesso adequado a agua potavel e questionavel para uma em cada seis pessoas que vivem atualmente. Assim, o presente trabalho centra-se mais no tratamento de agua contaminada com poluentes organicos e industriais toxicos atraves da fotocatalise. As nanoparticulas de oxido de estanho (SnO2) sintetizadas por co-precipitacao foram preferidas como catalisador para realizar a experiencia de fotodegradacao. A estrutura cristalografica e os parametros celulares foram calculados a partir de dados de XRD. A estrutura tetragonal e rutilica com parametros de celula calculados a=b=4,735 nm e c=3,185 nm. De acordo com a formula de Scherer, o tamanho medio dos cristais e de 11,40 nm. Foi efectuado um estudo termogravimetrico do precipitado antes da calcinacao para compreender as reaccoes termoquimicas que ocorrem durante a calcinacao. Finalmente, a atividade fotocatalitica foi conduzida contra o corante padrao, azul de metileno. A concentracao optima de solucao de azul de metileno 10-4M foi gradualmente degradada com a ajuda do fotocatalisador SnO2 sob irradiacao UV. O maximo de absorcao foi registado para diferentes intervalos de irradiacao UV. This item is printed on demand.
