|Abstract||A model for unsteady interactions between solar wind disturbances and the magnetosphere associated with the southward shift of the solar wind magnetic field during the growth phase of substorms is presented. It is emphasized that the presence of the solar wind electric current relating to the southward turning of the magnetic field and its interaction with the magnetosphere are essential in describing the transient process that generates the large-scale magnetospheric convection. Conceptual discussion on the stress generation due to the interaction in the outermost part of the magnetosphere and its transport into the inner magnetosphere and the high-latitude ionosphere are given. In comparison with the fast transient process, for instance, scc* of magnetic storms, the slow magnetosonic wave will play an essential role in the slow process, such as the early stage of the growth phase. By using the equivalent circuit model along with the above consideration the time response of the magnetosphere-ionosphere current system for this interaction is examined. The results indicate that a coupling of a rather large capacitance for the slow mode, in comparison with that for the Alfven mode, with the ionospheric resistance can yield a long time delay for the saturation of the ionospheric current.

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.
