Abstract | An EoN (Electrical impedance spectroscopy-On-a-Needle) with bipolar interdigitated electrodes at the very end of a hypodermic needle has been introduced. The device can be utilized to analyze the electrical impedance of biotissues for the purpose of discriminating between tissues prior to biopsy. A flexible photomask and photoresist spray coating were employed in the lithography process to realize the electrode pattern on the round surface of the needle. To evaluate the discrimination capability of the EoN, the impedance of the leg fat and muscle from a slaughtered chicken was measured over the frequency range 10 kHz to 1 MHz. The resistance and reactance were classified into two groups, which was in good agreement with the reported permittivity of fat and muscle tissues from bovines. |

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.
