|Abstract||The inhihition efficiency of HEDI' -Zn2 + system in cnntrolling corrosion of mild steel ill a nl'ut.-al u1lueous environment containing 60 ppm cr, a situation commonly encountered in couling water systems, has heen evaluated hy weight Inss study. Val-inus concenh-aliuns of HED!' (10, 50, 700 ppm) and variuus concentmtinns of Zn2 + (10, 50, 700, 150 ppm) have been used. A f41nllUlatiun is arrived at, which has 98% inhihition efficiency. The protective film has been analysed using X-my diffraction, F"fIR and uv-visihle reflectance spech�a. Tht' protective film conist~ of .'e*. HEDP complex and Zn(OH)2; free from any oxides of iron. The inl1uem'e of a biocide, namely, N-cl'tyl-N, N,N-trimethylammonium bromide (CrAR), on thl' corrosiun inhihition efficil'ncy of HEDP-Zn* system and also the influence of HErW-Zn* system on the biocidal effidt'ncy of CTAU have heen investigated.|

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 9 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.
