| Abstract | First results of ULF geomagnetic anomalies observed at the Tlamacas station (98deg 37' 41" W, 19deg 04' 01" N) located at 4 km near the volcano Popocatepetl (active volcano, 98.62 W, 19.02 N) for the period March-July, 2005 and their analysis are presented. The geomagnetic data were collected by a 3-axial fluxgate magnetometer designed at UCLA, (1 Hz sampling rate frequency, GPS). Our analysis reveals some anomalies, which are suspected to be generated by the local volcanic origin: the EM background in the vicinity of the volcano is significantly noisier than in other reference stations; the sporadic strong noise-like geomagnetic activity observed in the H-component; some geomagnetic pulsations (without preferred polarization) observed only at the Tlamacas station. Also the dynamics of the geomagnetic fractal index for the Tlamacas station in a comparison with the reference station points out to the some changes in critical processes, which may occur in the vicinity of the volcano. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built 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 designed 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 developed, operated and maintained from 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 Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
