|Abstract||A 3.63-g, 30-mm diameter U/sup 233/ specimen was irradiated in a 15-Mev neutron flux and placed on a polyethylene block containing 10 parallel-coupled BF/ sub 3/-filled counters; simultaneously, the high voltage was turned on. From the total decay curve corresponding to an irradiation of 300 seconds, the relative yields of all the groups were determined at the given half-life values. The thus- derived yield ratio of the first 2 groups was introduced into the equation system of the decay curve corresponding to an irradiation of 30 seconds; this allowed the relative yields of all the groups to be determined. The total yield of the delayed neutrons accompanying the fission of U/sup 233/ by 15.0-Mev neutrons was found to be 1.6 times larger than that of thermal and 3.8Mev neutrons, amounting to 0.780 plus or minus 0.066 of the total yield of delayed neutrons created by the fissioning of U/sup 235/ by thermal neutrons.

|Learning Resource Type||Article|
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.
