ABSTRACT: The object of this study is to extract the oil from millets and evaluate the chemical properties of the extracted oil. Commercial millet oil was obtained by cold solvent extraction adopting soxhlet procedure. Quantitative and qualitative tests concerned with the non-saponifiable matter, fatty acid composition, phosphorus content representing total phospholipids, refractive index, pero...
In this paper, we develop a dynamic system model to predict the effects of shale oil production on demand and supply of oil. We study the interaction between demand and supply of OPEC and non-OPEC member countries and supply of shale oil, oil price, growth of the global economy, development of new oil reserves and alternative energies. In our model, OPEC acts passively and covers the market d...
