Sidho Kanho Birsha University is a state university established in 2010 and situated in Purulia, West Bengal, India. Tapati Mukherjee has been appointed as the first Vice-Chancellor of the University. The focus of the University would be to promote and protect indigenous culture and language, and especially the Santali language.Sidho-Kanho-Birsha University began its nascent but promising journey as an academic institution of higher learning from the day it was created as a state University in 2010. Since then it has been a chronicle of consistent effort and ascendant drive to keep alive the dynamics of academic flourish. Currently the university is on the throes of novelty of vision and constitutive endeavours to script a new dimension in the annals of higher education. The Post-Graduate Departments of the university started functioning from the session 2011-12 with total number of twelve academic Departments . Over the years in an expansive and forward looking drive, we have enhanced the number into seventeen Departments with the introduction of five new departments many of which are situated in the frontier areas of Science and Social science. We are proud to initiate the Department of Tribal Studies to fulfill the mandate of the University which is situated in the remotest part of the State but having a vibrant social history and indigenous culture. We are soon going to open the Department of Performing Arts and introduction of such wings would provide a greater dimension in our efforts for growth and further development. The University is proud to have highly qualified faculty members, motivated students and adequate supporting and administrative officers and staff in order to absorb the forces of modernization and globalization in the field of Higher Education.Sidho Kanho Birsha University , Purulia aspires to be a premier center for advanced knowledge and top quality research.

Ethnopharmacological relevance In order to explore the traditional medicine practised by the ethnic communities residing in the topographically and climatically challenged Purulia, an underprivileged district of West Bengal, India, a quantitative ethnobiological approach was adopted to document the folkloric use of ethnomedicinals against different sexual, gynaecological and related ailments. Materials and methods Ethnobiological surveys were conducted during 2012-2015 by interviewing 82 informants or traditional healers with the help of a semi-structured questionnaire. The survey included questions on botanical and non-botanical ingredients and additives mixed with monoherbal and polyherbal formulations, vernacular names of the plants and animals, methods of preparation and administration and restrictions during medications. Additional quantitative indices such as use value, informant's consensus factor and fidelity level were used for data analysis. Results Twenty eight sexual and gynaecological disorders were found to be treated with 18 monoherbal and 31 polyherbal formulations consisting of a total number of 96 plant species from 86 genera and 47 families and four animal species. A variety of additives, either botanicals or non-botanicals were used with the formulations for higher efficacy and taste enhancement. Fabaceae (16 species) was found to be the most common family of medicinal plants whereas herbs (42.7%) and roots (32%) were the most common habit type and plant part used respectively. Use value's consensus factor and fidelity level indicate frequency and coherence of citations. Conclusion Age old belief on traditional medicine prevails in the studied area due to its efficacy, inexpensive price and the remoteness of tribal villages from conventional medical centres. Traditional healers had detailed knowledge of preparations, doses, methods of administration, restrictions during medications, safety and efficacy of using folkloric therapeutics against sexual and gynaecological disorders. Possible synergistic interactions among phytochemicals and additives were indicated to explain enhanced therapeutic efficacy of mixed herbal formulations. © 2015 Elsevier Ireland Ltd.

Reactive oxygen species (ROS) and free radicals are produced intrinsically during normal cellular metabolic processes or extrinsically due to ionizing radiations, UV rays, xenobiotic insult, etc. ROS are important signal mediators and are used by the immune system to destroy pathogens, but as these are highly reactive, they also have the capacity to cause DNA damage and alter protein and lipid components of a cell. As a result, cells have evolved a tight regulation of internal redox environment that involves a balanced interplay between free radicals produced and quenched by cellular antioxidants and enzyme systems. Any deregulation of this subtle balance can result in oxidative stress that can lead to various pathological conditions including cancer. Oxidative stress can be a cause of neoplasia, or it can be induced by a growing tumour itself. The link existing between oxidative stress and inflammation is also very strong. Suppressed cellular immune system, especially effector T cell system, is a characteristic of tumour-bearing host. Both the direct oxidative stress caused by tumour cell(s) and oxidative stress mediators present in tumour microenvironment play a significant role in the suppression of effector T cell function and induction of T cell death. This review discusses in detail the complex interplay between tumour-stroma-immune system in the light of oxidative stress that dominates every phase of cancer including initiation, progression and establishment. This review also addresses in detail the mechanisms of oxidative stress-induced T cell dysfunction in tumour-bearing host and also briefly points out the possible therapeutic interventions. © 2015 The Foundation for the Scandinavian Journal of Immunology.

Nanocrystalline layered perovskite Sr0.5A0.5Bi2Nb2O9 (A = Co2+, Ni2+, Cu2+) ferroelectric ceramics were synthesized through chemical process. The synthesized compounds were found to have tolerance values 0.90, 0.865 and 0.872 which are well within its limit. The electrical behaviour was thoroughly studied through impedance analysis within the temperature range between 400 °C and 500 °C after sintering the pressed pellet at 750 °C for 4h. Strong relaxation behaviour was found for Sr0.5Co0.5Bi2Nb2O9 and Sr0.5Cu0.5Bi2Nb2O9. The ac activation energy was calculated from the relaxation behaviour. All the studied samples showed grain conductivity behaviour only. The binding energy and density of states were studied with respect to temperature and frequency. The hopping behaviour was also studied and established a correlated barrier hopping model. © 2017 Springer Science+Business Media New York

A novel architecture of bidirectional gigabit signal transport system over long-haul single-mode fiber (SMF) using wavelength division multiplexed passive optical network technique is proposed and demonstrated. In order to offer multimedia services of high bandwidth, four signals of 5Gbps data rates are externally modulated and transmitted through four channels over 100-km SMF in uplink and downlink. In our proposed scheme, an excellent bit error rate, good Q-factor and clear eye diagrams are observed for both 100-km uplink and downlink transmission. This architecture has potential to transmit 4×5Gbps over long-haul fiber backbone and it will be useful in future broadband communications. © 2017 Walter de Gruyter GmbH, Berlin/Boston 2017.

A hybrid wavelength division multiplexing/time division multiplexing passive optical network (WDM/TDM) PON employing fiber-to-the-home (FTTH) for triple play services with 128 optical network units has been proposed and demonstrated, to transmit data, voice and video services simultaneously. 10 Gbps differential phase shift keying signal is employed to symbolize the internet and voice component. The radio frequency (RF) and sub carrier multiplexing scheme are utilized to comprehend analog video services. The multiplexed RF and data signal is modulated by external LiNbO3 phase modulator to mitigate chromatic dispersion and to obtain a small power penalty in receiver. The results show that FTTH triple play services can be successfully transmitted over a distance of 50 km with low transmission power penalties and better receiver sensitivity. High Q-factor, low bit-error-rate and excellent eye-diagram are achieved in our proposed network system and the results affirm the acceptability of proposed high capacity radio over fiber based hybrid WDM/TDM-PON. © 2017 The Optical Society of India

The occurrences of Pinus L. (family Pinaceae) megafossils (cones and leaf remains) have been abundantly documented from the Cenozoic sediments of eastern Asia (Japan and China), but none has been confirmed from the Indian Cenozoic till date. Here, we describe Pinus arunachalensis Khan and Bera, sp. nov. on the basis of seed remains from the middle to late Miocene Siwalik sediments of the Dafla Formation exposed around West Kameng district in Arunachal Pradesh, eastern Himalaya. Seeds are winged, broadly oblong to oval in outline, 1.3–1.5 cm long and 0.4–0.6 cm broad (in the middle part), located basipetally and symmetrically to wing, cellular pattern of wing is seemingly undulatory and parallel with the long axis of the wing. So far, this report provides the first ever fossil record of Pinus winged seeds from India. This record suggests that Pinus was an important component of tropical-subtropical evergreen forest in the area during the Miocene and this group subsequently declined from the local vegetation probably because of the gradual intensification of MSI (monsoon index) from the Miocene to the present. We also review the historical phytogeography and highlight the phytogeographic implication of this genus. © Indian Academy of Sciences.

Theoretical calculations of optical absorption (OA) spectra of Zn nanoparticles (NPs) in silica glass, using a simple model, have been resulted in appearance of three OA bands, all of which are found to blueshift with decrease in NP radius due to quantum confinement effects of free electrons. The intensities of the OA bands are seen to increase with increase in incident light energy. Importantly, all the three OA bands have been found to satisfy, accurately, the surface plasmon resonance (SPR) condition. All these observations clearly indicate that the observed OA bands are originated from the SPR absorptions in Zn NPs, but not due to inter-band absorption. © 2016 Springer Science+Business Media New York

The presence of multiple markets create profitable opportunities to the supply chain system. In this regard, this paper consists of the joint relationship between a manufacturer and multiple markets in which manufacturer offers part-payment to the markets due to their collection of finished products during the production run time. Here it is also considered that manufacturer is facilitated with credit period by raw material supplier where credit period has been presented as an interactive fuzzy fashion. In this paper, two types of deterioration have been assumed such as one for finished products and the other for raw materials. A solution algorithm is presented to get fuzzy optimal profit for the proposed integrated production inventory system optimizing production run time. A numerical example is used to illustrate the proposed model. Finally, sensitivity analysis has been carried out with respect to the major parameters to demonstrate the feasibility of the proposed model. © 2014 Elsevier B.V. All rights reserved.

Peak-to-total ratios have been extracted for a segmented clover detector for various modes of operation and suppression cases. Based on absorption and scattering of gamma-rays, a formalism has been presented for quantifying the advantages of using addback mode and active suppression. Further investigations have been performed to find if the reduction of background counts is caused more by active suppression or by addback process. © 2014 IOP Publishing Ltd and Sissa Medialab srl.

Full energy peak, single escape peak and double escape peak areas have been extracted for an escape suppressed clover detector. Results have been obtained for the single crystal and addback modes of operation as well as the active and passive suppression cases at several gamma energies. We have compared the ratio of single escape peak areas in addback mode with that of single crystal mode to study if the single escape peak gains or loses counts due to addback mode. Detailed analysis has been performed for quantifying the advantages of using addback mode and active suppression. Comparison is made for different types of clover detectors with different volumes. © 2014 IOP Publishing Ltd and Sissa Medialab srl.
