Compilation and Composition of Bituminous Coals

Mapping and Prediction of Coal Workers’ Pneumoconiosis with Bioavailable Iron Content in the Bituminous Coals

Based on the first National Study of Coal Workers' Pneumoconiosis (CWP) and the U.S. Geological Survey database of coal quality, we show that the prevalence of CWP in seven coal mine regions correlates with levels of bioavailable iron (BAI) in the coals from that particular region (correlation coefficient r = 0.94, p < 0.0015). CWP prevalence is also correlated with contents of pyritic sulfur (...

Effect of Gamma Irradiation on the Thermal Decomposition Behaviour and Electrical Resistivity of Some Indian Lignite and Bituminous Coals

It is known that irradiation of coal by high-energy and ionising gamma rays affects the structure of coal, as a result of which its physical and chemical properties are also likely to be and indeed are, affected or modified. Very little work has heen on this aspect of Indian coals, which are quite different from their foreign counterparts. From this point of view. over the past some years, the ...

Composition and Compilation in Functional Programming Languages

Functional programming languages, such as Backus' FP, and high level expression oriented languages, such as APL, are examples of programming languages in which the primary method of program construction is the process of composition. In this paper we describe an approach to generating code for languages based on compositions. The approach involves nding an intermediate representation which grow...

The first liquefaction of high-rank bituminous coals by preceding hydrogenation with homogeneous borane or iodine catalysts.

Parse Table Composition Separate Compilation and Binary Extensibility of Grammars

Module systems, separate compilation, deployment of binary components, and dynamic linking have enjoyed wide acceptance in programming languages and systems. In contrast, the syntax of languages is usually defined in a non-modular way, cannot be compiled separately, cannot easily be combined with the syntax of other languages, and cannot be deployed as a component for later composition. Grammar...
