Magnanimous Kunti by Samaresh Basu/ সমরেশ বসুর কলমে মনস্বিনী কুন্তী
No full textSamaresh Basu wrote a number of books based on Puran-Mahabharata under the pseudonym Bhramar and Kalkoot. Such as, ‘Shamba (1978)’, ‘Juddher Sesh Senapati (1984)’, ‘Prachetas (1984)’, \u27Pritha (1986)\u27, ‘Antim Pranay (1987)’ etc. ‘Pritha’ was published in the magazine \u27Prasad\u27 under the pseudonym \u27Bhramar\u27. In such books, the author analyzed the traditional story of the Puranas in a new perspective.
One of the memorable Panchakanyas in Puranas, Empress Kunti has been recreated in the light of the author\u27s spirit in this book. In the present article we will discuss how the character of Kunti has been recreated by Samaresh Basu in \u27Pritha\u27.
At the beginning of the story, before reaching the context of Kunti, the author undertakes a very realistic analysis of heaven-hell, Gods-demons, Samhita era-Puranic era, male-female relationship, marriage customs, child birth and the position of women in society. Then he explained the solitude, self-immolation and transition of Kunti from a feminist perspective.
The story of love-marriage-motherhood-heroism-restraint-pain-sacrifice of this remarkable female character of Mahabharata has been captured in a new way in the unique writing of Kalkoot. Inventing many thoughtful arguments the author tried to establish the father-son relationship between Yudhisthira-Vidura and Karna-Durbasha. How the author incarnated new contexts in the familiar story of Mahabharata and how he made it acceptable by arranging relevant arguments in favour of his new thoughts – this essay will try to elaborate these points
Non-thermal Plasma Synthesis of Carbon Nanoparticles
No full textThesis (Ph.D.)--Michigan State University. Chemical Engineering - Doctor of Philosophy, 2025Carbon nanoparticles are highly valued for their unique physicochemical properties and diverse applications in fields such as energy storage, catalysis, sensing, and biomedicine. These materials are typically produced through various chemical or physical processes; however, synthesizing well-structured carbon nanoparticles directly from methane\u2014a highly abundant but chemically inert greenhouse gas\u2014remains a significant challenge. Methane's strong C-H bonds and low reactivity often lead to the formation of amorphous carbon rather than the more desirable crystalline graphitic structures. This study addresses these limitations by leveraging a non-thermal flow-through plasma reactor to synthesize crystalline carbon nanoparticles directly from methane, demonstrating potential pathway for both greenhouse gas mitigation and material synthesis. Careful tuning of plasma reactor parameters enabled the controlled formation of crystalline graphitic nanoparticles. Transmission electron microscopy (TEM) provided clear evidence of graphitic crystallinity, showing well-defined lattice fringes that confirmed the structural quality of the synthesized nanoparticles. Optical Emission Spectroscopy (OES) identified the presence of the diatomic carbon radical (C2) within the plasma, a key precursor species necessary for nanoparticle formation. Laser-Induced Fluorescence (LIF) further complemented these findings by providing spatially resolved absolute density measurements of C2 along the reactor. These measurements revealed that C2 concentration was highest near the powered electrode, where the plasma is most intense, and gradually decreased downstream as the radicals were consumed in the growth of carbon nanoparticles. The insights gained from this study underscore the critical role of plasma parameters and reactive species in governing the synthesis process. By controlling the spatial and temporal dynamics of key intermediates like C2, it is possible to steer the growth of nanoparticles toward crystalline graphitic structures. This work not only advances the understanding of methane activation in plasma environments but also demonstrates the viability of using plasma technology as a sustainable and efficient route for transforming a potent greenhouse gas into high-value nanomaterials.Description based on online resource.

Etymology. This name “dinendra” is a patronym dedicated to Professor Dinendra Roychoudhury of Department of Zoology of University of Calcutta, who had encouraged the first author to carry out entomological research. Habitat. This species was collected from high mountainous cascades within the Neora Valley National Park of the Darjeeling District in West Bengal. The insects were found in steep, rocky areas flooded with splashing water, and appear adapted to the cold waters. A preference for rushing, high gradient upland streams has also been observed by the second author (DP) for another currently undescribed species of the Metrocoris compar species group collected in northern Vietnam, suggesting this habitat association may be typical of the group as a whole. Comparative notes. Metrocoris dinendrai sp. nov. belongs to Metrocoris compar group based on the structure of male fore femur, which is slender and slightly curved; the strongly curved male parameres; the elongate male pygophore which bears dense dark pilosity; and the laterally constricted female terminal abdominal sterna. This new species can be recognized within this group by the distinctive shape of male paramere, which has a a slightly expanded apex that is somewhat concave on its outer margin (Fig. 43); the structure of male endosomal sclerites (Fig. 44); and the female trochanter clothed with thick black bristles. Within the Metrocoris compar group, M. dinendrai seems most similar to M. pardus from the Malay Peninsula (Zettel, 2011a), but has the distal arm of the male paramere more slender and elongate, and the outer margin of the paramere apex concave rather than convex (compare Fig. 43 to Fig. 8 in Zettel, 2011a). The basal lobes on the male proctiger also are more angular than in M. pardus, whereas the internal sclerotization of the male endosoma is similar in both species.Published as part of Basu, Srimoyee, Polhemus, D.
