QUALITY OF PHYSICS INFORMATION SOURCES – WITH SPECIAL REFERENCE TO INDIAN JOURNAL OF PHYSICS
Get PDFScientific Publishing is one of the fastest growing sub-sectors of the media industry. Science, technology and medicine (STM) market is a stable and reliable field for long-term investments. Over the last few years it is evident that publication of STM journals is predominantly controlled by a few commercial publishers of USA and European Unions. With the acquisition of publications of learned societies and universities by a small number of large commercial publishers, very few STM journals published by learned societies of third world countries survived. One of the bright examples is Indian Journal of Physics.
The present study aims to divulge the pattern of scholarly communication of Indian Journal of Physics from 2007 to 2012 to measure the coverage and quality of contribution of this journal towards physics literature. Beside the journal itself mainly the Web of Science (WoS) online and Scopus Database online were used to collect the initial data. The study analyze the concept like chronological distribution of citation, distribution of affiliating institution, geographical distribution of contributors, description of subjects, ranking of cited journals and is concluded with a discussion of findings.The present study aims to divulge the pattern of scholarly communication of Indian Journal of Physics from 2007 to 2012 to measure the coverage and quality of contribution of this journal towards physics literature
Effects of viscocity variation and very high permittivity on the magnetic field effect in pyrene- dimethyl aniline exciplex emission
No full textMagnetic field induced change in the pyrene-N,N-dimethylaniline exciplex fluorescence
has been studied in condensed phase with very high permittivity. In contrast to the commonly
observed enhancement of exciplex fluorescence in presence of magnetic field (solvent
dielectric constant ranging between 7 to 33), the effect shows a complete reversal at
low DMA concentration in dimethyl sulfoxide (DMSO) which is observed only at the blue
end of fluorescence. At high DMA concentration the negative MFE at blue end slowly
reverts back to the normal. At the red end of the emission the MFE retains its normal
character for all donor concentrations even at very high permittivity.THESIS SUBMITTED FOR THE DEGREE OF

Indian Journal of Physics: A scientometric analysis
No full textPeer reviewed journals in the field of Science, Technology and Medical (STM) are the main vehicles through
which scientists publish their research output, communicate opinions and exchange observations. Governments
and industries of many countries are investing more money than before in science research. As a result, research
output in terms of publications of original research articles has been increased substantially in the recent past. So
there is a steady growth in STM journal publishing industries too. But unfortunately journals published by
universities and learned societies of third world countries are facing a stiff competition from large commercial
publishing houses and those are on the verge of extinction due to merger and acquisitions by large commercial
publishers. India is one of the fastest growing nations in terms of research output in science. Over the last few
years India is trying to establish herself as a global leader in science. The number of original research articles
published by Indian scientists has been increased substantially in the recent past. But very few journals in science
and specifically in the subject physics with high impact factor are published from India. As a result Indian scientists
have no choice but to use journals with high impact factor published from outside India to publish their research
output. Amongst the core physics journals published from India, Indian Journal of Physics (IJP) is one bright
exception. It not only survived the stiff challenges from commercial publishers but also excelled in many ways
that is clearly visible with steady increase in its impact factor over the last few years and for the year 2012 the
impact factor of IJP is 1.785 that is highest for any physics journal published from India and comparable with
other well known physics journals published from USA and European countries. Bibliometric and scientometric
studies were carried out for individual journals in the past for different purposes. IJP is now in the centre of
attention to physicists all over the world because of its reasonably good impact factor and the journal is getting
more number of original articles from all over the world. The objective of this study is to throw light on the factors
those play the vital role for the improvement of its quality by analysing different bibliometric and scientometric
data for IJP. The result of this study may be useful and the measures taken by IJP can be extrapolated to other
similar journals published by universities and societies from third world countries for improvement.10th International Conference on Webometrics, Informetrics and Scientometrics & 15th COLLNET Meeting 2014 during September 3-5, 2014 in Ilmenau Technical University, GermanyIndian Association for the Cultivation of Scienc
