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
Engineering a biomimetic environment to pre-condition stem cells for efficacious cardiovascular repair
No full textStatement of Purpose: Myocardial infarction (MI) is amongst the main causes of mortality worldwide, affecting people across a wide range of ages. Stem cell-based therapies are a viable approach to repair cardiovascular tissues due to their advantageous effect in promoting angiogenesis and decreasing scar tissue development. But, their translation to the clinic is hindered by their lack of ability to secrete sufficient therapeutic factors and poor differentiation in vivo. To combat this problem, various strategies like genetic modification and biophysical pre-conditioning have aimed at enhancing the efficacy of stem cells for cardiovascular tissue regeneration
Post-Reform Development in Asia: Essays for Amiya Kumar Bagchi
No full textThis festschrift volume for professor Amiya Kumar Bagchi dwells on issues often raised in the development debate whether neo-liberal reforms in developing nations have raised inequality and poverty, food insecurity, hindered empowerment of women, aggravated agrarian distress, reallocated resources for private profitability and facilitated the rise of multi-national oligopoly according inferior status to the domestic industries in the host countries most of the issues have been examined on the basis of empirical data drawn from China, India and Bangladesh essays on china concentrate on post-reform issues of inequality across regions and rural-urban locations and its failure to achieve targets of human development while experiencing rapid economic growth discussions on changes in policy environment since the early days of the people\u27s republic of china also constitute the basic themes of the essays food insecurity, growth-poverty-employment relationship, gender discrimination in the labour market and agrarian distress caused by withdrawal of state support to small farmers growing commercial crops and revision of priority sector lending policy at the cost of small farmers and entrepreneurs are the major themes of essays written in the Indian context of post-reform development in an essay on Bangladesh the poverty issues has been revisited in the context of child work agrarian issues have also been raised in an essay where the author proposes an alternative peasant social construction for the dual affirmation of land rights of the state and of the peasant family in the last two essays authors look far beyond the mainstream tradition to develop an analytical framework for understanding issues relating to the recent rise of multi-national firms and the phenomenal growth of India\u27s software technology. -- Provided by publisherhttps://scholarworks.uni.edu/facbook/1150/thumbnail.jp

No full textAmiya Kumar Bagchi, an eminent economist of the modern
Cambridge tradition, has produced a timely treatise, in a condensed
form, on the development problems of the Third World countries. The
author's general thesis is that economic development in the developing
societies necessarily requires a radical transformation in the economic,
social and political structures. As economic development is actually a
social process, economic growth should not be narrowly defined as the
growth of the stock of rich capitalists. Neither can their savings be
equated to capital formation whose impact on income will presumably
'trickle down' to the working classes. Economic growth strategies must
not aim at creating rich elites, because, according to the author,
"maximizing the surplus in the hands of the rich in the Third World is
not, however, necessarily a way of maximizing the rate of
growth"

A geometric proof of a theorem on antiregularity of generalized quadrangles
No full textA geometric proof is given in terms of Laguerre geometry of the theorem of Bagchi, Brouwer and Wilbrink, which states that if a generalized quadrangle of order s > 1 has an antiregular point then all of its points are antiregular. © 2011 The Author(s).published_or_final_versionSpringer Open Choice, 21 Feb 201
