Item Assessment of bio-concentration factor of heavy metals in Indian soil-crop system(Scientific Publishers, 2017) Yadav, P.; Garg, V.K.; Singh, B.; Mor, S.Bioaccumulation of heavy metals in different agricultural products in soil-crop systems has fascinated pervasive attention in yester years due to food safety issues. The objectives of this study were to determine the influence of different soil parameters on bio-concentration of heavy metals? from soil to pearl millet grains. For the purpose, heavy metals were quantified in pearl millet grains and corresponding fields? rhizospheric soil samples from different study sites in Haryana, India. The mean concentrations of Cd, Pb, Ni, Zn, Fe and Cu in pearl miller garins were found to be 0.50, 6.74, 3.86, 49.72, 142.0 and 10.17 mg kg?1 respectively. Pearl millet showed capacity to transfer essential metals Zn and Cu from soil to grains while showed a restricting effect to the uptake of Co and Cr. Further multivariate statistical techniques like correlation analysis, principal component analysis and cluster analysis were applied to the data for supplementary and qualitative evaluation of inter-dependences among the studied parameters. Bio-concentration factors of all the studied heavy metals in pearl millet grains showed significant negative correlations with their respective soils? total metal concentrations. The results revealed lesser metal uptake with increasing soil total metal concentrations. Inspite of the variability in the characteristic of investigated soils, significant correlations among soil quality parameters and metal accumulation in grains were recorded. Cluster analysis revealed formation of many primary cluster pairs such as EC-Na, CEC-Ca, BCFNi-Cus, BCFFe-TOC, BCFzn-EC, BCFPb-pH, BCFCu-Na and CdS-Pbs etc. ? 2017, Scientific Publishers.

Drinking water samples collected from different sources, viz., hand pumps, tube-wells, and public water supply from Sonipat and Panipat districts of Haryana, India have been analyzed for uranium and other physico-chemical parameters. Uranium concentration in water samples was measured using Pulsed LED Fluorimeter. Uranium concentration in collected water samples ranges from 9.1 to 155.1 ?g/L in Sonipat district and 14.9 to 123.3 ?g/L in Panipat district. It was inferred from the data that uranium concentration in some water samples was higher than WHO & USEPA recommended limit of 30 ?g/L. The mean cancer risk due to uranium in drinking water in Sonipat and Panipat districts was found to be 1.40 ? 10?4 and 1.63 ? 10?4, respectively, which is lower than the maximum permissible limit (<10?3). Total Dissolve Salts (TDS) in water samples of some villages in Sonipat district was higher than permissible limits for drinking prescribed by WHO & BIS. ? 2018 Taylor & Francis Group, LLC.Item Bioaccumulation and health risks of heavy metals associated with consumption of rice grains from croplands in Northern India(Taylor and Francis Inc., 2017) Yadav, P.; Singh, B.; Garg, V.K.; Mor, S.; Pulhani, V.The present study focused on micronutrients and nonessential toxic heavy metals quantification and their bio-concentration in soil?rice system in Haryana, India. Composite samples of rice grains and paddy fields' soil were collected, processed and analyzed for heavy metals. Nutrient and heavy metals' content of paddy fields' soil varied over a wide range, having highest Fe content followed by Cu > Cr > Pb > Ni > Zn > Co > Cd. Most of the metals viz. Fe, Zn, Cu and Co found profusely in rice grains were essential micronutrients. Bio-concentration factors (BCFs) in rice grains were in the following order: Zn (0.11) > Co (0.10) > Cu (0.08) = Cr (0.08) > Ni (0.02) > Pb (0.011) > Cd (0.009) > Fe (0.003), indicating higher accumulation of micronutrients than non-essential toxic heavy metals. Principal component analysis revealed three factors accounting for 70% of the total variance which supported correlation among electrical conductivity (EC)-Na, EC-cation exchange capacity (CEC), CEC-Na, pH-TOC, and BCFCu-BCFZn. Health risk indices anticipated that the grains are safe for consumption as non-carcinogenic hazard quotients were less than unity for all the studied heavy metals. ? 2017 Taylor & Francis Group, LLC.Item Contributions of Indian authors in the subject category law of the web of science core collection: A bibliometric analysis(University of Tyumen, 2020) Kumar, D; Singh, B.This paper presents a bibliometric analysis of research works in the subject category Law published with the affiliation of India in the Web of Science Core Collection. A total of 529 published works by Indian authors from Indian law schools and institutions on or relating to the subject of the law have appeared in law journals and other sources. The works are indexed in the Core Collection for the years 1999�2019 and have been cited 2,041 times over this 20-year period. To conduct the analysis of the published data based on norms such as author-wise, country-wise and citation-wise figures, normative bibliographic techniques were applied to attain the objectives. After a detailed discussion of the analysis of the data, the research arrives at the conclusion that Indian authors have fewer published works in the subject category Law in the Core Collection than two other Asian countries, but that there has been a gradual increase in their number since 2011. � 2020, University of Tyumen.

CP and SP were rich in proteins and minerals (Cu, Fe, Zn, Mg, Ca, K and Na). Their blending significantly influenced the physicochemical and antioxidant properties of CG extrudates. TPC and AOA of extrudates increased with the increased incorporation of CP and SP, though specific mechanical energy and extrudate expansion, generally, decreased while density and hardness increased. Sensory analysis revealed that CP and SP at incorporation levels of 25% and 4%, respectively could be blended with CG for making highly acceptable antioxidant-rich expanded snack. © 2019, Association of Food Scientists & Technologists (India).Item Making sense of cancer through autobiography: suffering, stigma, and regeneration in Lance Armstrong's It's not about the bike(Routledge, 2017) Singh, B.The present paper through a discussion of the therapeutic value of autobiographical narratives of disease seeks to emphasize the importance of Lance Armstrong?s autobiography, showing how someone after once having physically and emotionally devastated by a disease like cancer, and bearing the stigma of socio-cultural myths and constructions of the disease can come out triumphant and attain regeneration through an indomitable will to survive and live. ? 2016 National Association for Poetry Therapy.Item Sino-Pakistan Friendship, Changing South Asian Geopolitics and India's Post-Obama Options(Sage Publications India Pvt. Ltd, 2017) Ahmad, P.; Singh, B.In the context of changing global geopolitics, South Asia as a global pivot amongst major regions and powers has recently acquired a more central geostrategic position. China and Pakistan have long been sharing strong political, cultural and economic relations and are portrayed as all-weather friends, amplifying their engagement to secure their respective specific interests within and outside the region. This Sino-Pakistan link has been treating India as a collective target, with China acting contrary to India?s interests also in light of rising Indo-US strategic leverage. Against this complex backdrop, which also implicates Central Asia, the ultimate focus of this article is to locate India?s geostrategic interests and future prospects in view of the strong Sino-Pak friendship. Our key findings suggest that in this new ?Great Game?, Indo-US links are going to become even more crucial, but that India should not just wait for US decisions. ? 2017 SAGE Publications.Item Transfer Factors and Effective Dose Evaluation Due to Natural Radioactivity in Staple Food Grains from the Vicinity of Proposed Nuclear Power Plant(Springer Netherlands, 2018) Yadav, P.; Garg, V.K.; Singh, B.; Pulhani, V.; Mor, S.This study focused on quantification of radioactivity concentration of naturally occurring radioactive materials 40K, 226Ra and 232Th in most staple food grain i.e. wheat of the study area using gamma spectrometry?for two years. 40K, 226Ra and 232Th activities were detectable in most of the wheat grain samples and ranged 111.3?245.7, <0.04?0.37 and <0.015?0.11?Bq?kg?1 respectively. Effective dose due to the consumption of radionuclides via wheat grains was calculated on its estimated annual intake by the local populace. Also to evaluate transfer factors of radionuclide?s, corresponding fields? soils were collected and assessed for their radioactivity content. Measured average radioactivity levels in soils from the site were in order: 40K (544.7???14.6?Bq?kg?1)?>?226Ra (41???1.6?Bq?kg?1)?>?232Th (32.3???1.2?Bq?kg?1) and comparable to the corresponding levels obtained worldwide. The geometric mean transfer factors of studied NORMs in wheat grains were in order: 40K (0.371???0.07)?>?226Ra (0.003???0.002)?>?232Th (0.001???0.001). Significant positive dependencies of transfer factors of 40K, 226Ra and 232Th in wheat grains were observed with total organic carbon content of soil. Estimated annual effective doses from ingestion of the wheat were 1.37E?01?mSv year?1 for 40K, 4.14E?03?mSv year?1 for Ra226 and 1.10E?03?mSv year?1 for 232Th, well under the permissible cumulative global average.. ? 2017, Springer Science+Business Media Dordrecht.Item Xi Jinping?s vision of South Asia: An appraisal of problems and potentials for India(Taylor and Francis, 2018) Singh, B.; Thoker, P.A.Under the leadership of Xi Jinping, a paradigmatic shift has been witnessed in China?s foreign policy goals from geopolitical interests to economic ones towards the international community in general and South Asia in particular. Concerning the South Asian region, China has expressed its willingness to adopt a trilateral approach, that is China, India, and other notable South Asian countries. In this complex geopolitical trilateralism, China will pose serious geopolitical and geoeconomic problems despite expanding economic engagements. India, being a close neighbour of China, figures prominently in China?s South Asian policy objectives. However, China?s strategic support to India?s long-standing rival Pakistan and involvement in Pakistan-occupied Kashmir (PoK) are being considered as major challenges for India. Apart from this, it is comprehensively engaged with the other neighbouring countries. On the other hand, its economic engagement with the region will open significant opportunities, not only for India but also for the entire South Asian region. In this backdrop, the primary focus of this chapter is to analyse China?s new approach under the leadership of Xi Jinping vis-?-vis South Asia and India?s overall position considering possible challenges and potential areas of cooperation. ? 2018 selection and editorial matter, Geeta Kochhar; individual chapters, the contributors.
