|Abstract||As the demand for greater throughput and shorter turnaround times for analytical work is increasing, instrumental neutron activation analysis (INAA) has come under pressure to substantially improve its performance in these areas. Of course, such improvements are expected without any loss of quality in other performance parameters, such as precision and accuracy. The National Institute of Standards and Technology (NIST) is responding to the aforementioned demands with increased utilization of short-lived ultrashort-lived nuclides and high-rate counting techniques in INAA. Part of this effort involves, in the course of the renovation of the NIST research reactor irradiation laboratories, the establishment of a newly designed gamma-ray spectrometry facility with three high-rate, high-resolution germanium detectors. The three detectors allow simultaneous counting of three samples and/or standards irradiated at the same time. The detector systems have been evaluated in a preliminary setup and are now being relocated in close proximity of the irradiation terminals to achieve short sample transfer times.|

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.
