To evaluate the impact of hypoxia (<2 mg O2 l−1) on habitat quality of pelagic prey fishes in the northern Gulf of Mexico, we used a spatially explicit, bioenergetics-based growth rate potential (GRP) model to develop indices of habitat quality. Our focus was on the pelagic bay anchovy Anchoa mitchilli and Gulf menhaden Brevoortia patronus. Positive GRP was considered high-quality habitat (HQH)...

Energy is one of the most basic of human needs. The accomplishments of civilization have largely been achieved through the increasingly efficient and extensive harnessing of various forms of energy to extend human capabilities and ingenuity. Providing adequate and affordable energy is essential for eradicating poverty, improving human welfare, and raising living standards worldwide. The Persian...

Flow rates of oil, gas and water are most important parameters of oil production that is detected by Multiphase Flow Meters (MFM). Conventional MFM collects data on long-term, because of the radioactive source is used for detection and in unmanned location used due to being away from wells. In this work, a new method based on feed-forward artificial neural network (ANN) and Imperialist Competit...

the aim of this research is to simulate oil spill behavior in the persian gulf due to the wind andtidal currents. this is achieved by coding an oil spill mathematical model consisting of several major submodels including hydrodynamic model, oil slick dynamic model and oil weathering model. the base of all of them is eulerian approach and they are coupled together to simulate spill incident in t...

a r t i c l e i n f o JEL classification: D44 L71 Keywords: Oil and gas lease auctions Asymmetric information National oil company This paper analyzes bidding behavior in oil and gas tract auctions in Brazil, where the main winner has been Petrobras, a national company. We test predictions from the theory of common-value, first-price, sealed-bid auctions with asymmetric information. The tests i...

vital importance of the energy in national and international economic development has made oil as a crucial and attractive factor for great powers. these powers have had permanent competition for establishing an oil system for securing their national interests. the persian gulf has been focal point of these competitions. after september 11, 2001, the role of oil has considered as one of the mos...

The Persian Gulf is an important economic and geo-political region. Owing to its oil and gas resources, it is one of the busiest waterways in the world. There are many operating oil wells in the northern part of the Persian Gulf . As a result, the risk of contaminant dispersion is high. The deliberate discharge of 6.3 million barrels of crude oil during the 1991 war against Kuwait in this regio...
