One key ingredient used in the formulation of aquafeed is fish oil, which is produced from small marine pelagic fish and represents a finite fishery resource. At the present time, global fish oil production has reached a plateau and is not expected to increase beyond current levels. Recent estimates suggest that fish oils may be unable to meet demands from the rapidly growing aquaculture indust...

because iran’s economy is based on oil industry, related issues in this area are very important. one of the important issues in this context is the low participation of oil industry in the total portfolio of the insurance industry that suggests numerous challenges in the interaction between the two. in addition, the imposition of international sanctions against oil projects and oil shipping ins...

Wildlife campaigners are hoping to do a deal with the burgeoning oil palm industry in Borneo in the hope of creating a forest framework to save the threatened orang-utan. Palm oil companies and the Sabah government in Borneo have agreed to a project to create wildlife corridors that will link forest areas and create a network of safe havens for the ape. Palm oil companies and the Sabah governme...

Dependent bigrams are two consecutive words that occur together in a text more often than would be expected purely by chance. Identifying such bigrams is an important issue since they provide valuable clues for machine translation, word sense disambiguation, and information retrieval. A variety of significance tests have been proposed (e.g., Church et. al., 1991, Dunning, 1993, Pedersen et. al,...

This article explores the relationship between rising rates of violent crime and suicide in the oil producing region of western North Dakota during a time of rapid expansion for the oil extraction industry. The objectives of this article are: (1) to introduce the preliminary findings of a larger study that examines the rising rates of crime and other social problems within the socioeconomic con...

The American oil shale industry is on the threshold of commercial industrial development. Potential occupational hazards include shalosis or oil shale pneumoconiosis, dermatoses, cancer of the skin, lung, and possibly other sites, and accidents. Air, water, and solid waste pollution problems are complicated by the aridity of the Green River oil shale formation located in Utah, Colorado, and Wyo...

In the oil industry, huge saving may be made if suitable multi-interface level measurement systems are employed for effectively monitoring crude oil separators and efficient control of their operation. A number of techniques, e.g. externally mounted displacers, differential pressure transmitters and capacitance rod devices, have been developed to measure the separation process with gas, oil, wa...

since the strategies and plans for e-commerce development are different for different industries and since the oil industry is one of the most important industries in Iran, the scope of this research is thus confined to that of the oil industry in Iran. The main aim of this study is to identify and classify the different features of e-commerce development stages and features based on the differ...

The US shale exploration and production (E&P) industry has grown since 2007 due to the development of new techniques such as hydraulic fracturing and horizontal drilling. As a result, the share of shale gas in the US natural gas production is almost 50%, and the share of tight oil in the US crude oil production is almost 52%. Even though oil and gas prices decreased sharply in 2014, the product...
