A interpreting his views on the development of science and their commemoration of the 50th anniversary of the publication of the original version of Kuhn＇s epoch-making book The Structure of Scientific Revolutions （henceforth： SSR） should thus provide a thorough reflection on this thesis. However, this thesis is not easy to interpret. It is not only complex in itself but has also undergone a historical development--in Kuhn＇s own hands and in those of his interpreters. In this article, I sort out the different interpretations of it, in particular, in Part A. In Part B, I demonstrate their epistemological consequences. Under closer scrutiny, Kuhn＇s incommensurability-thesis contains several sub-theses Different senses of ＂incommensurability＂ thus need to be distinguished. However, the way in which those distinctions are drawn in Kuhn-scholarship differs. In paragraph I of Part A, I provide an overview of the reception of the incommensurability-thesis in Kuhn-scholarship. In Paragraph II, I trace its development in Kuhn＇s later writings： given its importance and contested nature, Kuhn later clarifies his original thesis. Those later clarifications＇ main function consists in domesticating the most radically relativistic aspects his original incommensurability-thesis had, at least, in the eyes of his interpreters. The upshot of Part A （Paragraphs I and II） is to provide a coherent interpretation of Kuhn＇s incommensurability-thesis. To that end, I distinguish in line with much of Kuhn-scholarship a semantic from a methodological sense of incommensurability. In part B, the question is raised： What sort of epistemological consequences follow from both senses of incommensurability？ In particular, what consequences follow for the issues of reference, subjectivity （objectivity）, pluralism, and realism？ The underlying question is to what extent Kuhnian incommensurability caters to a relativistic understanding of those issues. This question is answered in Paragraph Ill with the help of the analyses of a currently leading Kuhn-scholar, C. H. Sankey. His answers are taken as a vantage point for my concluding evaluation of the consequences of Kuhnian incommensurability in Paragraph IV.展开更多

Further, the average heat to power ratio (kWth/kWe) of sponge iron plants ranges from (25:1) to (31:1). This shows that the manufacturing process mostly uses thermal energy and application of electrical energy is insignificant. The main & only source of thermal energy is coal and the entire coal is fed to the rotary kiln. Therefore we find that “Kiln” is the “Black-Box” of this industry and the success of energy efficiency is hidden in the kiln process chemistry. This article tries to establish detailed energy audit methodology of sponge iron manufacturing process or kiln operation with a view to finding out major energy saving potential of the unit. In the research work we find that it is the incomplete reaction of coal that causes the major energy inefficiency in the process. Substantial amount of un-reacted carbon comes out with the char (by-product) which has virtually zero commercial value. The article also puts a question mark on the justification of using high-grade imported coal in such energy inefficient industries.展开更多
