Faunal Remains from Girawad (2006-2007), District Rohtak, Haryana
No full textThe Harappan site of Girawad was excavated for a single season in 2006‐07 by excavators from Deccan College, Pune; MD University, Rohtak and Research Institute for Humanity and Nature, Japan to salvage fast‐vanishing archaeological record. This single culture site, circular in plan and 8 ha in area, lies 3 km to the east of the present village of Girawad. Altogether 41 trenches revealed 13 pitdwelling complexes with ceramics similar to Hakra Ware which portrays a regional variation that can roughly be dated to middle of Fourth Millennium BC. The faunal material (n=4671) from this site was analyzed at the Archaeozoology Laboratory at Deccan College, Pune following internationally standardized procedures. This paper throws light on the diverse faunal spectra and the role and contribution of different mammalian and non‐ mammalian species to the human subsistence at Girawad. Methods used include NISP, skeletal representation and a minute study of pre and post depositional bone modifications generated by anthropogenic and other causal agents in the background of their contexts

Ni–Co–S–Se Alloy Nanocrystals: Influence of the Composition on Their in Situ Transformation and Electrocatalytic Activity for the Oxygen Evolution Reaction
No full textThe
electrocatalytic oxygen evolution reaction (OER) is an important half
reaction in various technologies, such as metal air batteries and
electrochemical water splitting. Transition metal chalcogenides, especially
those based on Co and Ni, are emerging as promising OER catalysts,
thanks to their high activity and low cost. However, it is still being
debated whether they act as actual catalysts or as catalyst precursors,
undergoing structural and morphological changes under OER conditions.
To gain a better comprehension of this topic, we have developed a
simple colloidal synthesis method for alloy nanocrystals (NCs) based
on Ni, Co, S, and Se with a tunable composition, and we studied their
structural and morphological evolution during OER. We found that binary
CoSe, ternary Ni–Co–Se and quaternary Ni–Co–S–Se
NCs, with the exception of NiSe, each undergo structural and morphological
changes under OER conditions, forming the corresponding metal oxides/hydroxides,
which act as the actual active catalysts. Interestingly, we discovered
that the composition of the starting metal chalcogenide NCs plays
a major role in dictating the crystallinity, conductivity and activity
of such oxide/hydroxide materials. This compositional tuning, that
is going from CoSe to Ni0.25Co0.65S0.4Se0.6 NCs, resulted in a ∼7 fold improvement in
the OER activity in terms of turnover frequency. Our results suggest
that the compositional engineering of metal chalcogenide materials
could potentially be used to control their inevitable transformation
into the corresponding oxide/hydroxide counterparts, eventually improving
their OER activity
Historiografía feminista con referencia especial de Pandita Ramabai y Tarabai Shinde
No full textIn colonial Maharashtra women tried to converse with themselves and the society through biographies, autobiographies, articles in newspapers, journals and they even wrote books, trying to discuss women\u27s issues that arose from the patriarchal system of society at the time. They criticized social customs and blind faith in religion pertaining women, very intensely. Their writings were theoretical and visionary, and stood out creating a baseline for feminist historiography; here my efforts are to interpret their writings from that point of view. The first part of this paper discusses the efforts of feminist historiography as a whole and the second part is based on the book, "The High Caste Hindu Woman" and "Stri-Purush Tulana" by Pandita Ramabai and Tarabai Shinde respectively.En el Maharashtra colonial, las mujeres intentaron conversar con ellas mismas y con la sociedad a través de biografías, autobiografías, artículos en periódicos, revistas e incluso escribieron libros, tratando de discutir los problemas de las mujeres que surgieron del sistema patriarcal de la sociedad en ese momento. Criticaron muy intensamente las costumbres sociales y la fe ciega en la religión de las mujeres. Sus escritos fueron teóricos y visionarios, y se destacaron creando una línea de base para la historiografía feminista; Aquí mis esfuerzos son para interpretar sus escritos desde ese punto de vista. La primera parte de este documento discute los esfuerzos de la historiografía feminista en su conjunto y la segunda parte se basa en el libro "La mujer hindú de la casta alta" y "Stri-Purush Tulana" de Pandita Ramabai y Tarabai Shinde, respectivamente
