| Abstract | Extracorporeal shock wave lithotripsy (ESWL) has recently become the preferred procedure for the treatment of urinary and gall bladder stones. The device used in this treatment generates acoustic shock waves which are focused onto the stone, causing it to disintegrate. Interest in studying the properties of the shock waves quantitatively has intensified, since it is believed that the acoustic shock wave parameters, such as rise time, peak positive and peak negative pressure amplitudes, and frequency content, may influence the treatment's efficiency. In the present work the authors describe the evaluation of several piezoelectric materials and design configurations for their applicability to quantitative shock wave measurement. Preliminary experimental results indicate that PVDF (polyvinylidene fluoride) polymer sensors with a low acoustic impedance backing have the greatest potential as shock wave sensors. |

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.
