Life cycle of glaciers in the Himalayan region has notably changed due to the climatic variability since last few decades. Glaciers across the world and specially the Himalayan glaciers have shown large scale degeneration in the last few decades. Himalayan glaciers serve as an important fresh water resource for the downstream communities, who are dependent on this water for domestic and other purposes. Therefore, glacier shrinkage and the associated hydrological changes pose a significant problem for regional-scale water budgets and resource management. These issues necessitate the regular and rigorous monitoring of the wastage pattern of the Himalayan glaciers in field and using satellite remote sensing data. In this work, we report rapid and enhanced degeneration of the frontal part of the Kangriz glacier, Jammu and Kashmir(J & K), in terms of surface melting, debris cover, snout characteristics and meltwater discharge. Ablation data acquired during 2016-2017 shows the average lowering of the frontal part of the glacier to be ~148 ± 34 cm, one-third of which was found to have occurred within a 13 day time period in September, 2017. Also, the quantum of ice melt was found to be inversely influenced(r =-0.84) by the debris thickness. 15 day meltwater discharge measurement revealed its strong relationship with snout disintegration pattern, evidenced twice during the said time period. Volume of water discharged from the glacier was estimated to be 7.91×10~6 m^3 for the measurement duration. Also, mean daily discharge estimated for the 15 days interval showed good positive correction(r = 0.78) with temperature indicating the direct dependency of the former on land surface temperature conditions of the region. Besides the lowering and discharge observations, the frequent ice-block break-offs at the glacier snout further enhance its overall drastic degeneration. The study suggests that, being the largest glacier in the Suru basin, the Kangriz glacier needs to be continuo

Applying the classical Lie symmetry approach to the barotropic and quasi-geostrophic potential vorticity equation without forcing and dissipation on a β-plane channel, we find a new symmetry, which is not presented in a previous work [F. Huang, Commun. Theor. Phys. （Beijing, China） 42 （2004） 903]. A general finite transformation group is obtained based on the full Lie point symmetry, Furthermore, two new types of similarity reduction solutions are obtained.

Record of Additional Middle Eocene Vertebrate Remains from the Mikir Hills, NE India: Implications on Paleoenvironment and Paleobiogeography

International Journal of Geosciences 2022年第8期13卷 609-626页

作者： Shantajhara Biswal Kapesa Lokho Annie Needham Ansuya Bhandari uma kant shukla Kezhakielie Whiso Kuldeep Prakash Wadia Institute of Himalayan Geology Dehradun India Department of Geology Banaras Hindu University Varanasi India Department of Geology School of Basic and Applied Sciences Sri Guru Ram Rai (P.G) College Dehradun India Birbal Sahni Institute of Paleosciences Lucknow India Ampeli Danda Lackhond Shastradhara Road Dehradun India

The fossiliferous middle Eocene deposits of Sylhet Limestone of Mikir Hills have yielded vertebrate and invertebrate faunas. The fossil assemblages recorded in this contribution consist of shark, ray, crocodile, conical tooth, broken fragments and echinoderm spines. Ray and crocodile tooth are reporting for the first time from the Mikir Hills. Paleoenvironmental analysis based on the fossil fish assemblage in association with invertebrate (foraminifera) remains and sedimentogical observations suggest a shallow marine environment ranging from open marine, inner neritic to more proximal coastal settings. Also, the presence of common marine elements (similar faunas) from Kutch, Rajasthan, Himachal Pradesh, Assam (India), New Hampshire, Libya, Iraq, Iran, North Western Sahara (Algeria), Tanzania (East Africa), Italy, Germany, Southern North Sea basin (Europe) based on previous published works and the present finding testifies to the connection of the Tethys Sea during Lutetian-Bartonian of middle Eocene.

Justice and Civic Friendship： An Aristotelian Critique of Modern Citizenry

引用

Frontiers of Philosophy in China 2014年第1期9卷 1-20页

作者： Rajesh C. shukla School of Public Ethics Saint Paul University Ottawa K 1S 1 C4 Canada

Modem moral and political theorists make a sharp separation between justice and civic friendship, arguing that justice deals with the fair terms of co-operation in the social sphere whereas civic friendship is about an individual＇s contingent affections in the political domain. In addition, they also argue that the principles of justice must determine the nature and function of civic friendship in modem liberal society. Even though the historical origin of the above view can be traced to the writings of Immanuel kant （2007）, John Rawls provides us with its most cogent formulation in recent times. In his book A Theory of Justice （1971）, Rawls argues that the considerations of right are prior to the considerations of good; therefore the principles of justice must determine the limits of civic friendship. Against RaMs, I argue that justice and civic friendship are intrinsically connected and that they cannot be separated in experience. I draw upon Aristotle＇s theory of virtue to strengthen my arguments. Following Aristotle, I show that both justice and friendship are virtues and that all virtues hold together. The Aristotelian coherence of virtues, I argue, can be useful in redefining the obligations of justice and civic friendship in contemporary liberal democracies.

High Performance Polymer Light-Emitting Devices

World Journal of Nano Science and Engineering 2014年第1期4卷 16-20页

作者： Vivek kant Jogi School of Studies in Electronics Pt. Ravi Shankar Shukla University Raipur India

In order to improve the performance of polymer light-emitting devices, driving voltages, current efficiency, luminance and power efficiency of different cathode metals such as Ca/Al, CsF/Al, LiF/Al and LiF/Ca/Ag were compared. The results show that cathode metals CsF/Al contain the highest current efficiency, maximum luminance and power efficiency. Therefore, we can choose the CsF/Al to be the cathode for improving the performance of polymer light-emitting devices.
