Bacillus pumilus strain CCMA-560 was isolated from an oil-contaminated mangrove swamp and was shown to produce biosurfactants. The strain appears to be capable of degrading some plant cell wall-related compounds, including hemicelluose and pectin. Genes for biopolymer export and polysaccharide intercellular adhesin synthesis were also annotated.

Crude oil blending is an important unit operation in petroleum re…ning industry. A good model for the blending system is bene…cial for supervision operation, prediction of the export petroleum quality and realizing model-based optimal control. Since the blending cannot follow the ideal mixing rule in practice, we propose a static neural network to approximate the blending properties. By input-t...

In 2013, China imported 282 million tons of crude oil with an external dependence of 58.1%, surpassing the USA as the world’s largest net oil importer. An import source diversification strategy has been adopted by China to ensure oil supply security and to prevent oil supply disruption. However, the strategy is restricted by the imbalance of oil reserves. What is the reasonable and clear object...

the economy's dependence on oil revenues and derivatives of these products make the country's economy heavily influenced by the volatility and instability of the pricing of these products. therefore, it seems necessary to develop non-oil exports. this paper examines the causality relation and the effect of foreign direct investment, economic openness and real exchange rate on non-oil ...

The objective of this paper is to investigate the impacts of implementation of the FTAA and China’s lower import tariffs on international trade of soybean oil, soybean meal, and soybeans. A two-commodity spatial model was formulated. The base model was calibrated to simulate the average level data of 1996, 1997, and 1998. Two alternative trade scenarios were simulated. The results indicated tha...

this paper investigates the short- run and long-run effects of government size and exports on the economic growth of iran as a developing oil export based economy for the period of 1974 - 2008 using an autoregressive distributed lags (ardl) framework. a modified form of feder (1982) and subsequently ram’s (1986) model has been applied to include both government size and exports in growth equati...

Agricultural products export has main role among non-oil exports and pistachio is the most important exportable agricultural product in Iran. In this research we tried to deal with the most important weak and strong spots, opportunities and threats facing the advertisement of exporting pistachio in Kerman province. This has been done with the usage of factor analysis (PFA) in combination with S...
