|Abstract||HCl yields from irradiated chloroform are, for doses at least as high as 1.3 x 10/sup 2//sup 1/ ev per gram, greater at 70 plus or minus 4 deg than at 20 deg . The initial G-value at the higher temperature is 31 compared with an average of 11.9 at 20 deg . Chlorine yields from irradiated carbon tetrachloride are slightly smaller at 70 plus or minus 4 deg than at 20 deg . The corresponding G-values are 0.58 and 0.65. The addition of hexachloropthane to carbon tetrachloride prior to irradiation causes a nearly linear decrease in G(/ sub C//sub l//sub 2/) with per cent hexachlorothane. The addition of hexachloroethane to chloroform prior to irradiation causes, at low doses, an increase in G(/sub H//sub C//sub l/) above that in pure chloroform. G(/sub H// sub C//sub l/) in chlorofo rmhexachloroethane mixtures decreases with dose and above approximately 1 x 10/sup 2//sup 1/ ev per gram, becomes less than in pure chloroform. These results are discussed in terms of free radical mechanisms. (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.
