| Abstract | The suitability of the two more extensively used sampling techniques, namelyin-situ dialysis and centrifugation followed by filtration were compared. Field measurements derived from Lake Simbirizzi, Sardegna, Italy were used for the comparison. Two groups of substances were selected; the first one consists of the relatively inert in the aquatic environment chlorides and bromides, while the second one consists of substances involved in diagenctic processes (ammonium-nitrogen and soluble reactive phosphorus). The field measurements show that for the applied sampling techniques the measurements are comparable for the first group of substances, while measurements derived by centrifugation followed by filtration give considerably different concentrations usingin-situ dialysis for the second group of substances. Since the second group is related to sediment-water interactions (adsorption-desotption and chemical processes), it seems that forced separation by centrifugation influences considerably die derived measurements. As a resultin-situ dialysis is expected to give more accurate measurements of porewater concentrations for nutrients and other reactive substances. |

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.
