Dr. Biman Bagchi a bibliometric portrait
No full textAnalyses bibliometrically 226 publications [Papers Published in journals-220, thesis [others 4] by Biman Bagchi, a renowned physical chemist from India, published during 1981 to 2002. The first contribution of the author was in 1981 at the age of 27. The number of his contributions in a year peaked in 1999 and 2002 when it touched 19. The author is highly productive in as much as on average the author has produced 10 papers per year. In the byline of authorship, Bagchi occupies the first authorship position in 69 cases. His collaborator A. Chandra occupies the first authorship position in 30 papers thus becoming Bagchi's closest collaborator. The journal has been the most preferred channel of communication of the author in as much as 220 papers out of 226 have been praced in journals. J. Chem. Phys. is found to be the most preferred journal that carried 91 papers of the author, followed by Chem. Phys. Lett. (21 papers). J. Phys. Chem. (19 papers), Proc. Indian Acad. Sci. - Chem. Sci. (13 papers), and others. Of the papers, 179 received 4030 citations and 47 received no citations. It is expected that more than 20 uncited papers till 2002 will receive citations in future. Three papers of the author have received more than 200 citations each, and another three received between 100-200 citations each. The number of papers receiving 10 citations or more total 92. On four different years the scientist has received more than 300 citations and his citation rate per paper has peaked at 18.98. The article shows with a concrete example the growth, peaking and declining of citation rate. A few new terms such as citation gain, citation loss, gaining citation rate and losing citation rate have been introduced and described

An analytic solution of the non-linear equation ∇2λ(r)=f(λ) and its application to the ion-atmosphere theory of strong electrolytes
No full textFor a long time the formulation of a mathematically consistent statistical
mechanical theory for a system of charged particles had remained a formidable unsolved problem. Recently, the problem had been satisfactorily solved, (see Bagchi [1] [2]) ,by utilizing the concept of ion-atmosphere and generalized Poisson-Boltzmann (PB) equation. Although the original Debye-Hueckel (DH) theory of strong electrolytes [3] cannot be accepted as a consistent theory, neither mathematically nor physically, modified DH theory, in which the exclusion volumes of the ions enter
directly into the distribution functions, had been proved to be mathematically consistent. It also yielded reliable physical results for both thermodynamic and transport properties of electrolytic solutions. Further, it has already been proved by the author from theoretical considerations (cf. Bagchi [4])as well as from a posteriori verification (see refs. [1] [2]) that the concept of ion-atmosphere and the use of PB equation retain their validities generally. Now during the past 30 years, for convenice of calculations, various simplified versions of the original Dutta-Bagchi distribution function (Dutta & Bagchi [5])had been used successfully in modified DH theory of solutions of strong electrolytes. The primary object of this extensive study, (carried out by the author during 1968-73), was to decide a posteriori by using the exact analytic solution of the relevant PB equation about the most suitable, yet theoretically consistent, form of the distribution function. A critical analysis of these results eventually led to the formulation of a new approach to the statistical mechanics of classical systems, (see Bagchi [2]), In view of the uncertainties inherent in the nature of the system to be discussed below, it is believed that this voluminous work, (containing 35 tables and 120 graphs), in spite of its legitimate simplifying assumptions, would be of great assistance to those who are interested in studying the properties of ionic solutions from the standpoint of a physically and mathematically consistent theory

The mu vector, Morse inequalities and a generalized lower bound theorem for locally tame combinatorial manifolds
No full textIn a recent work (Bagchi and Datta, 2014) with Datta, we introduced the mu-vector (with respect to a given field) of simplicial complexes and used it to study tightness and lower bounds. In this paper, we modify the definition of mu-vectors. With the new definition, most results of Bagchi and Datta (2014) become correct without the hypothesis of 2-neighbourliness. In particular, the combinatorial Morse inequalities of Bagchi and Datta (2014) are now true of all simplicial complexes.As an application, we prove the following generalized lower bound theorem (GLBT) for connected locally tame combinatorial manifolds. If M is such a manifold of dimension d, then for 1≤ℓ≤d-12 and any field F,gℓ+1(M)≥(d+2ℓ+1)∑i=1ℓ(-1)ℓ-iβi(M;F). Equality holds here if and only if M is ℓ-stacked.We conjecture that, more generally, this theorem is true of all triangulated connected and closed homology manifolds. A conjecture on the sigma-vectors of triangulated homology spheres is proposed, whose validity will imply this GLB Conjecture for homology manifolds. We also prove the GLB Conjecture for all connected and closed combinatorial 3-manifolds. Thus, any connected closed combinatorial manifold M of dimension three satisfies g2(M)≥10β1(M;F), with equality iff M is 1-stacked. This result settles a question of Novik and Swartz (2009) in the affirmative
Analyzing Toru Dutt’s Oeuvre Today: How a Transnational Literary-Educational Case from Colonial India Can Enrich Our Conception of Transnational History
No full textBagchi argues that our conceptualization of the transnational in educational history is enriched by examining the multicentric histories and educational trajectories of Toru Dutt. She analyzes the transnational educational history of Dutt’s life as writer-in-the-making. A teenage prodigy who produced an astonishingly varied and rich corpus in a life that spanned India and Europe, before dying at the age of twenty-one, Dutt created a transnational literary and cultural space for her own work. Bagchi demonstrates that, using a feminist lens, we can recognize the character and enriching quality of such transnational female friendships and networks. While Dutt can be situated in the concepts of imperial as well as critical and vernacular cosmopolitanism, cosmopolitanisms need to be seen as important in our conceptualization of the transnational
