| Abstract | Summary form only given. We carried out $NO_{x}$ removal test using co-axial non-thermal plasma reactor driven by inductive energy storage system pulsed power generator with focusing influence of primary capacitor capacitance on $NO_{x}$ removal. Semiconductor opening switch (SOS) diodes are employed as opening switch. A primary capacitor is charged up negatively to the voltage using a dc high voltage power supply. The charges are released from the capacitor by switching-on a gap switch mechanically, as the results, the current flow to the LC circuit through the SOS diode as forward-pumping current. After the current direction reverses with LC oscillation, the reverse current is injected into the SOS. With the current interrupted by the SOS, tire high voltage pulse is applied to the high voltage electrode as a short nanosecond pulse. This nanosecond pulse produces the streamer discharges homogeneously. A co-axial cylinder plasma reactor, which consists of 1 mm diameter tungsten wire and 19 mm i.d. copper tube with 30 cm in length, is employed as the nonthermal plasma reactor. The gas mixture of 200 ppm NO diluted with $N_{2}:O_{2}=9:1$ is used as a simulated diesel engine exhaust gas. The gas flow rate is 2 l/min. The energy efficiencies of NO removal are around 16 g/kWh at 50 % removal when the capacitance is in range from 100 to 500 pF. However, the energy efficiency decreases to 3.5 g/kWh with increasing capacitance of the primary capacitor from 500 pF to 4.2 nF. This efficiency decrease is caused by glow discharge generation. |

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.
