Free swelling index (FSI) is an important parameter for cokeability and combustion of coals. In this research, the effects of chemical properties of coals on the coal free swelling index were studied by artificial neural network methods. The artificial neural networks (ANNs) method was used for 200 datasets to estimate the free swelling index value. In this investigation, ten input parameters ...
Large deposits of coal over vast expanse of lands attract mining companies, power stations and petrochemical companies and thus the development of coal towns with rail and road networks. High traffic volume of large quantities of coal across coal cities often result in the gradual accumulation of fine coal dust particles on road pavements, rail ballast and sleepers. The effect of coal dust on t...
BACKGROUND We consider the problem of optimizing a liposomal drug formulation: a complex chemical system with many components (e.g., elements of a lipid library) that interact nonlinearly and synergistically in ways that cannot be predicted from first principles. METHODOLOGY/PRINCIPAL FINDINGS The optimization criterion in our experiments was the percent encapsulation of a target drug, Amphot...
Coal is most important fossil fuel in world. Energy requirement of world is increasing in many fields day by day. The crude oil and coal are the main backbone of energy. Since the reserves of crude oil are decreasing day by day as a result the coal becomes the main sources of fossil fuel. Ash content of Indian coal is very high ranging from 15% to 55% [1]. Ash is an inorganic compound present i...
Background and objectives Mining results in degradation of rangelands ecosystem structure and function. Coal mining in rangelands produces significant quantities of waste dumps in mining area which are considered as the main environmental pollutants in the site and surrounding ecosystems. Vegetation restoration in mining area could reduce soil pollution and could be of great help in restoring ...
