Scientometric dimensions of technical reports from Bhabha Atomic Research Centre

Technical report is one of the media to record the scientific information generated by scientists and engineers, Bhabha Atomic Research Centre (BARC) published 554 technical reports during 1990-99 under the categories: External (373) and Internal (181), Engineering and technology generated 207 technical reports followed by chemistry, materials and earth sciences (129), while their interdisciplinary interactions resulted in 31 technical reports, Life and environmental sciences produced 42 technical reports,' followed by Physics (16),' Other aspects of nuclear and non-nuclear energy (6); Isotopes, isotope and radiation applications (4), Technical reports in subjects outside the scope of nuclear science and technology were 69, Scientometric analysis of these reports has been carried Out for physical bibliographic characteristics, authorship collaboration, inter-divisional collaboration, inter-institutional collaboration activities and content analysis, Types of documents referenced in the technical reports indicated first rank for journal articles, followed by books, technical reports, conference papers, standards/codes, personal communications, patents, theses, drawings, and lectures

Statics and dynamics of phase segregation in multicomponent fermion gas

We investigate the statics and dynamics of spatial phase segregation process of a mixture of fermion atoms in a harmonic trap using the density functional theory. The kinetic energy of the fermion gas is written in terms of the density and its gradients. Several cases have been studied by neglecting the gradient terms (the Thomas-Fermi limit) which are then compared with the Monte-Carlo results using the full gradient corrected kinetic energy. A linear instability analysis has been performed using the random-phase approximation. Near the onset of instability, the fastest unstable mode for spinodal decomposition is found to occur at $q=0$. However, in the strong coupling limit, many more modes with $q\approx K_F$ decay with comparable time scales.Comment: 14 figure

Effective usage of e-resources

There is large quantity of subscribed e-resources which contain quality rich information in most of the technical institute libraries. In spite of advantages in terms of access and search capabilities, they are underused. Systematic plan has to be in place for their promotion of use. While a good ICT infrastructure is a prerequisite, it alone will not do. Proactive strategies are required and these need to be adopted imaginatively. Access to e-resources need to be made easier for both on campus and off campus users. Training will increase the confidence level of the users. Traditional awareness methods include: Personal visits, orientations, brochures, posters and displays. Newer technologies from the Web 2.0 such as RSS alert service, Blogs, Wikis and Face book make the interaction with the library not only interesting but also add more value
