|Abstract||The production of magnesium-28 by pile-produced tritons simultaneously- results in considerable sodium-24 contamination. The degree of contamination was determined for magnesium precipitates by precipitating magnesium ammonium phosphate, magnesium oxalate from homogeneous solution, and magnesium-8- quinolinolate both by the conventional method and from homogeneous solution. The extent of sodium and potassium coprecipitated decreased in the order: phosphate method (single precipitation)> phosphate method (double precipitation)> oxalate method> quinolinolate method> quinolinolate method from homogeneous solution. In this last case the amount of sodium coprecipitated per 69 mg of magnesium ranged from 0.02 to about 1 gamma for 0.4 to 4000 mg of sodium added. Adsorption is believed to be responsible for the contamination in most cases. TMe results show the quantitative accuracy and reproducibility of the magnesium-8quinolinolate procedure for precipitation from homogeneous solution. (auth)|

Ministry of Human Resource Development (MHRD) under its National Mission on Education through Information and Communication Technology (NMEICT) has initiated the National Digital Library of India (NDLI) project to develop a framework of virtual repository of learning resources with a single-window search facility. Filtered and federated searching is employed to facilitate focused searching so that learners can find out the right resource with least effort and in minimum time. NDLI is designed to hold content of any language and provides interface support for leading vernacular languages, (currently Hindi, Bengali and several other languages are available). It is designed to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is being developed to help students to prepare for entrance and competitive examinations, to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is being developed at Indian Institute of Technology Kharagpur.
NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Human Resource Development (MHRD), through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
