|Abstract||Clear cut differences in the protein and esterase pattenns were shown in the irradiated and control halves of rat brains. The changes induced by acute doses of x radiation in the esterases of brain cells and blood serum after crandial exposure appeared, on the basis of the differences in electrophoretic migration and substrate-inhibitor activity, to be largely inigenous to the respective systems. The most profound changes occurred in blood. Several of the esterase components of the blood serum zymogram patterns were decidedly inactivated by irradiation while the brain tissue zymogram patterns exhibited an apparent increase, or a decrease in the activity of certain esterolytic proteins. It was concluded that these divergencies in the zymogram patterns may not only represent additions or deletions of enzymatically active molecules from the various cellular elements comprising the brain tissue, but also certain ancillary changes in their structural configurations and charge distributions as well.

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.
