| Abstract | This work reports the feasibility of a nondestructive synchrotron radiation X-ray transmission imaging technique development at Brazilian synchrotron light source. The quality control image parameters (spatial and density resolution and noise) were available and tomography preliminaries were evaluated. Microtomograms of biomedical samples are presented. The tomographic system was mounted into the XRF beamline that uses a high intensity white beam with 12 keV effective energy, and maximum width and height equals to 11 mm and 1 mm, respectively. The detector used to collect the data was a 512-pixel EG&G Reticon linear array with width of 50 /spl mu/m (36 /spl mu/m of sensitivity length ) and cooled by a Peltier junction, causing the temperature falling down to 15/spl deg/C. The samples were placed over a computer controlled table with 0.5 degree angular resolution and turned around the center covering 360 degrees. To reconstruct the sample was used a parallel beam filtered backprojection algorithm. |

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.
