This paper develops an econometric framework for the analysis of exploration and production policies of "price-taking" suppliers, and derives theoretically-consistent exploration and output equations for oil which explicitly take account of the oil discovery process and the intertemporal nature of exploration and production decisions. The framework is then applied to an empirical analysis of oi...

Background: Orange peel essential oils were obtained using supercritical fluid extraction. This method is an important high scaling extraction methods that used for extraction of plant and animal extracts. Methodology: The experimental parameters of SFE such as temperature, pressure, and extraction time and modifier volume were optimized using a central composite design after a 24-1fractional ...

investment in oil and gas upstream activities is very important for the exploration and development of oil and gas fields. different and various laws and regulations deal with the investment in upstream operations. by reviewing these various laws and regulations, this research paper tries to discuss to what extent these laws and regulations have created legal confident for foreign investment up...

Nanotechnology has the potential to introduce revolutionary changes to several areas of oil and gas industry such as exploration, production, enhanced oil recovery, and refining. In this paper, the effect of different concentrations of Fe2O3 nanoparticles as a catalyst on the heavy oil viscosity at various temperatures is studied. Furthermore, the effect of a mixture of Fe2O3 nanoparticles and ...

cinnamon is the bark the cinnamomi cassia that exhibits many medical properties such as anti-cancer effect and anti-diabetic effect. moreover, because of its antioxidant activity; it can be used in food industries. many studies have already reported biological and chemical properties of the cinnamon extracted essential oil such as their antimicrobial, antifungal, antimosquito, free radical scav...
