Mumbai, India

The University of Mumbai , erstwhile the University of Bombay or informally Bombay University, is one of the first three state universities in India, located in the city of Mumbai in the state of Maharashtra. It is abbreviated as either "UoM" or "MU" .The University of Mumbai offers Bachelors, Masters and Doctoral degrees apart from diplomas and certificates in many disciplines. The language of instruction for most courses is English. A majority of private colleges are also affiliated to MU. One of its two campuses in Mumbai is located in Kalina, Santacruz. The campus houses academic and administrative departments. Another campus located in Fort carries out administrative work only. Several world-renowned institutes in Mumbai were affiliated to the university. Most of them are now autonomous institutes or deemed universities. The University of Mumbai, is one of the largest universities in the world in terms of the number of students. In 2011 the total number of enrolled students was 5,49,432. It has 711 affiliated colleges. Wikipedia.

The x-ray wavelengths and rates from double electron radiative transitions in Li isoelectronic sequences are evaluated for 17 ions with 14≤Z≤54 using fully relativistic multiconfiguration Dirac-Fock wave functions in the active space approximation with the inclusion of finite nuclear size, Breit interaction, self-energy, and vacuum polarization. A detailed discussion on the anomalous mixing coefficients contributions to the 1s2s(3S 1)3p 2P1/2 level for ions with 38≤Z≤43 is given. The sensitivity of transition rates to the Breit interaction is also analyzed. The present results are compared with other available theoretical data. The errors associated with the transitions are highlighted for some of the strongest lines, taking into account the uncertainties on the fine-structure energy levels and also on the line strengths. © 2013 American Physical Society.

We predict proton radioactivity and structural transitions in high spin state of an excited exotic nucleus near proton drip line in a theoretical framework and investigate the nature and the consequences of the structural transitions on separation energy as a function of temperature and spin. It reveals that the rotation of the excited exotic nucleus 94Ag at excitation energies around 6.7 MeV and angular momentum near 21h{stroke} generates a rarely seen prolate non-collective shape and proton separation energy becomes negative which indicates proton radioactivity in agreement with the experimental results of Mukha et al. for 94Ag. © 2010 .

Purpose: The purpose of this paper is to investigate LIS instructors' familiarity with Web 2.0 concepts, tools and services, and applications related to LIS education. Design/methodology/approach: The survey method was used and the data collection tool was a web questionnaire, which was created with the help of software provided by surveymonkey.com Findings: It was found that LIS instructors, in some Indian universities, have a low level of familiarity regarding the use of Web 2.0. Most of the instructors use Web 2.0 for video sharing via YouTube. Nearly, half of teachers have never used Wikis. The main problem in use of Web 2.0 in teaching was the lack of training programs organized by universities and other institutions for instruction in the use/teaching of Web 2.0 tools. Research limitations/implications: The state government-funded universities of the Maharashtra state of India were considered for the study. Originality/value: This is one of the first papers focusing on the use of web 2.0 tools in teaching by LIS instructors in India. © Emerald Group Publishing Limited. Source

Quantum confinement and surface effects (SEs) dramatically modify most solid state phenomena as one approaches the nanometer scale, and superconductivity is no exception. Though we may expect significant modifications from bulk superconducting properties when the system dimensions become smaller than the characteristic length scales for bulk superconductors - such as the coherence length or the penetration depth - it is now established that there is a third length scale which ultimately determines the critical size at which Cooper pairing is destroyed. In quasi-zero-dimensional (0D) superconductors (e.g. nanocrystalline materials, isolated or embedded nanoparticles), one may define a critical particle diameter below which the mean energy level spacing arising from quantum confinement becomes equal to the bulk superconducting energy gap. The so-called Anderson criterion provides a remarkably accurate estimate of the limiting size for the destabilization of superconductivity in nanosystems. This review of size effects in quasi-0D superconductors is organized as follows. A general summary of size effects in nanostructured superconductors (section 1) is followed by a brief overview of their synthesis (section 2) and characterization using a variety of techniques (section 3). Section4 reviews the size-evolution of important superconducting parameters - the transition temperature, critical fields and critical current - as the Anderson limit is approached from above. We then discuss the effect of thermodynamic fluctuations (section 5), which become significant in confined systems. Improvements in fabrication methods and the increasing feasibility of addressing individual nanoparticles using scanning probe techniques have lately opened up new directions in the study of nanoscale superconductivity. Section6 reviews both experimental and theoretical aspects of the recently discovered phenomena of 'parity effect' and 'shell effect' that lead to a strong, non-monotonic size dependence of the superconducting energy gap and associated properties. Finally, we discuss in section7 the properties of ordered heterostructures (bilayers and multilayers of alternating superconducting and normal phases) and disordered heterostructures (nanocomposites consisting of superconducting and normal phases), which are primarily controlled by the proximity effect. © 2014 IOP Publishing Ltd.

Back in the mid-1980s, a new branch of investigation related to the interaction of eta mesons with nuclei came into existence. It started with the theoretical prediction of possible exotic states of eta mesons and nuclei bound by the strong interaction and later developed into an extensive experimental program to search for such unstable states as well as understand the underlying interaction via eta-meson producing reactions. The vast literature of experimental as well as theoretical works that studied various aspects of eta-producing reactions such as the π+n → p, pd → 3He, p 6Li → 7Be η and γ 3He → η X, to name a few, had but one objective in mind: to understand the eta-nucleon (ηN) and hence the η-nucleus interaction which could explain the production data and confirm the existence of some η-mesic nuclei. In spite of these efforts, there remain uncertainties in the knowledge of the ηN and hence the η-nucleus interaction. Therefore, this review is an attempt to bind together the findings in these works and draw some global and specific conclusions which can be useful for future explorations. The ηN scattering length (which represents the strength of the η-nucleon interaction) using different theoretical models and analyzing the data on η production in pion, photon and proton induced reactions was found to be spread out in a wide range, namely, 0.18 e aηN 1.03 fm and 0.16 m aηN 0.49 fm. Theoretical searches of heavy η-mesic nuclei based on η-nucleus optical potentials and lighter ones based on Faddeev type few-body approaches predict the existence of several quasibound and resonant states. Although some hints of η-mesic states such as He and Mg do exist from previous experiments, the promise of clearer signals for the existence of η-mesic nuclei lies in the experiments to be performed at the J-PARC, MAMI and COSY facilities in the near future. This review is aimed at giving an overall status of these efforts. © 2013 IOP Publishing Ltd. Source
