Hazaribag, India

The Vinoba Bhave University is located at Hazaribagh, India and is funded by Government of India. The university came into existence on 17 September 1992 after the bifurcation of Ranchi University as a teaching-cum-affiliating university. Being among one of the premier universities of Jharkhand, it offers high standards of teaching and research. The university offers courses at the undergraduate and post-graduate levels.The Governor of Jharkhand is the chancellor of Vinoba Bhave University. The university has a distinguished alumni body and faculty. This university is also a member of Association of Commonwealth Universities, London. The UGC, New Delhi recognized the university and registered it under section 12B of the UGC Act 1956. Wikipedia.

The Shiala Formation of the Garhwal-Kumaon subbasin of the Tethyan Himalaya, has been sampled for chitinozoans in the Chamoli district of Uttarakhand, India. The greenish gray colored silty shale at the lower horizon of Shiala Formation yielded a relatively rich though poorly diverse assemblage of chitinozoans. The chitinozoans are mostly acceptably well-preserved. The assemblage is dominated by two species, i.e. Belonechitina capitata and Belonechitina micracantha with rare specimens of Conochitina chydaea. These microfossils are very poorly documented from the low-latitudinal part of Gondwana and this is the first time that they are reported from this part of globe. The chitinozoan data are from below the Ordovician-Silurian boundary as indicated by an acritarch study from the same section, which is in agreement with our identification of the species that suggest a Mid to Late Ordovician age. © 2011 Elsevier B.V.

A novel design of a single-channel thermally tunable photonic filter by cascading two one-dimensional (1D) superconductor-dielectric photonic crystals (SDPCs) through low loss silica fiber for wavelength selective switching (WSS) application is being presented theoretically. This filter is capable to separate and switch unique wavelength channel (without interfering with each other) from 12 equally spaced wavelength channels adopted by the International Telecommunication Union (ITU). It may be used in wavelength division multiplexing (WDM)-based optical networks for routing signals at specific wavelengths into an optical fiber with minimum distortion. This idea may also be explored in the design of very precise thermal sensing devices for remote sensing applications. © Springer Science+Business Media New York 2015.

Belonechitina capitata, a typically middle to late Ordovician chitinozoan index taxon was for the first time recovered from the northeastern Kumaon region, a part of Garhwal-Kumaon Tethys basin of the Himalaya, India. This species is of great biostratigraphic importance and has already been reported from Avalonia, Baltica and northern Gondwana. The study area was during Ordovician, part of a low-palaeolatitudinal Gondwana region. The vesicles of recovered forms are black and fragmentary. This is principally attributed to intense tectonic activity during the Himalayan orogenic movement which resulted into high thermal alteration. The chitinozoans are found along with melanosclerites. © 2015 China University of Geosciences (Beijing) and Peking University.

A simple relation between the bulk modulus, plasmon energy, electronic polarisability are given for ternary chalcopyrite semiconductors. Bulk modulus has been evaluated from plasmon energy by proposing a linear relation between them. From bulk modulus electronic polarisability has been evaluated. The estimated values are in good agreement with the experimental values and earlier researchers. © 2010 IACS.

Propagation of electromagnetic waves in one-dimensional plasma dielectric photonic crystals, the superlattice structure consisting of alternating plasma and dielectric materials, is studied theoretically for oblique incidence by using the transfer matrix method. Our results show that complete photonic band gaps for all polarizations can be obtained in one-dimensional plasma dielectric photonic crystals. These structures can exhibit a new type of band or gap, for the incidence other than the normal one, near frequencies where the electric permittivity of the plasma layer changes sign. This new band or gap arises, from the dispersive properties of the plasma layer, only for transverse magnetic polarized waves, and its width increases with the increase in incident angle. This differential behavior under polarization can be utilized in the design of an efficient polarization splitter. The existence of both photonic gaps and resonance transmission bands is demonstrated for experimentally realizable structures such as double electromagnetic barriers.
