Impact of Open Access Educational Resources in Library and Information Science Domain: A Study
No full textThe growth of the internet and the developments in Information Communication Technologies (ICTs) highly influenced the teaching and learning process. Open Access Resource (OER) generally designated as teaching, learning, and research materials freely available under the Open License domain. This paper discusses the different segments of OER and evaluates their impact in the LIS domai
Library Knowledge Portal: an advanced User Interface for Disseminating Services
No full textDigital libraries are complex information systems, which run on the Internet. Their facilities are increasing daily with the advances in the technology. The purpose of the digital libraries is to provide the required information to its users in a convenient format in time. Since the digital libraries are running on the Internet and the users are from different psychological, educational and social backgrounds, the usage of digital libraries is varying from user to user which necessitates the best user interface. Hence web sites providing single point of access to applications and information is important. The paper discusses library’s knowledge portal, technologies used, digital resources, web sites, and related services
Improved Efficiency of a Linearly Homomorphic Cryptosystem
No full textWe present an extended version of the Castagnos and Laguillaumie linearly homomorphic cryptosystem in which the non-maximal imaginary quadratic order is allowed to have conductor equal to a power of a product of distinct primes as opposed to a single prime. Numerical results obtained with an optimized C implementation demonstrate that this variation improves performance when large messages and exponents are used. When compared to the cryptosystems of Paillier and Bresson et al. at the same security levels, the basic version of Castagnos and Laguillaumie is the fastest at high security levels for small messages
Enhancement Effects of Biosurfactant Produced by Pseudomonas aeruginosa MTCC 2297 and Pseudomonas fluorescens on Sugar Cane Bagasse Composting
No full textBiosurfactant produced by Pseudomonas aeruginosa MTCC2297 and Pseudomonas fluorescens (a Mangrove forest isolate) was added to the Sugar cane bagasse decomposing process to initiate and enhance the production of reducing sugars. Both isolates produced a glycolipid biosurfactant, namely a rhamnolipid that was confirmed by biochemical and analytical studies. The surface tension of fermentation broth reduced from 73 to 34.2 mN/m by P. aeruginosa MTCC 2297 and from 76 to 29 mN/m by P. fluorescens. Sugar cane bagasse decomposing process was attempted by two different methods, adding pure rhamnolipid and on-site production of it were compared. The study revealed that rhamnolipid concentration of 0.75gl-1 was optimum for composting process and the optimum temperature for compost pile production was 32°Cfor the first 48h subsequently 35°C for the next 48h. At the optimum temperature for this two-stage fermentation, the production of reducing sugar could be increased to 15.73 gl-1 for P. aeruginosa MTCC 2297 and for the P. fluorescens reducing sugar increased to 15.88 gl-1, both experiments resulted in higher values than that of the treatment without rhamnolipid sample. The results indicate that application biosurfactant could possibly reduce the composting period. As the compost pile production of rhamnolipid does not require the purification process, the production cost reduced significantly.--------------------------------------------------------------------------------------------------------Department of Microbiology, Faculty of Agriculture, Annamalai University, Annamalai Nagar, Chidambaram, Tamil Nadu, India-608002. *Corresponding author, Email: [email protected], Mob: +91-9842059688               Cite This Article As: Parthasarathi, R. and  P.

Electromagnetic and gravitational scattering at Planckian energies
No full textSherpa Romeo green journal. Permission to archive final published versionThe scattering of pointlike particles at a very large center-of-mass energies and fixed low momentum transfers, occurring due to both their electromagnetic and gravitational interactions, is reexamined in the particular case when one of the particles carries a magnetic charge. At Planckian center-of-mass energies, when gravitational dominance is usually expected, the presence of magnetic charge is show to produce dramatic modifications to the scattering cross section as well as to holomorphic structure of the scattering amplitude.Ye
