The presence of heavy metals in plants from oil sand deposits may reflect mineralization resulting petroleum biodegradation. Petroleum composition and metal analyses were performed using thermal desorption gas chromatography atomic absorption spectrophotometry on plant root samples the same localities Dahomey Basin. results showed mainly heavy-end hydrocarbon components, humps unresolved comple...

There are many challenges associated with development of offshore petroleum fields. Subsea production facilities are increasingly used in the petroleum industry as the technology has matured and quality increased. The use of subsea technology has advantages as well as challenges. Based on a literature review this paper identifies some if the development challenges related to the design and oper...

Aquamicrobium defluvii W13Z1 was isolated from petroleum-contaminated drill cuttings from the Bohai Sea and could degrade petroleum hydrocarbon with 5% NaCl at 15°C. Here, we present the 4.8-Mb draft genome sequence of this strain, which may provide useful information about the mechanism of petroleum degradation in drill cuttings.

The relevance of this study is due to the need replace petroleum diesel fuel with motor fuels obtained from alternative raw materials. Rapeseed oil and ethyl alcohol are considered as promising fuels. use these biofuels a makes it possible solve problem reducing carbon dioxide emissions into atmosphere switch carbon-neutral energy. possibility using mixtures for engine considered. Poor flammabi...

BACKGROUND In general, organic solvents are inhibiting many physiological enzymes and alter the behavioural functions, but the available scientific knowledge on laboratory solvent induced organ specific toxins are very limited. Hence, the present study was planned to determine the sub-chronic toxic effects of petroleum ether (boiling point 40-60°C), a laboratory solvent in Sprague-Dawley (SD) r...

The aim of this communication was to expand the results of numerical analyses performed by Sun et al. on their experimental solubility of fenofibrate in aqueous mixtures of ethanol and acetone at 298.15 K, in terms of the evaluation of the preferential solvation of this compound by the organic solvents and water in the saturated mixtures based on the inverse Kirkwood-Buff integrals (IKBI). ...

Petroleum ether extract of Caesalpinia bonduc L. (Roxb) seeds (Family: Caesalpiniaceae) was evaluated for its anti-inflammatory activity in rats. Wistar rats (120-150 g) of either sex were pretreated with petroleum ether extract of seed kernel of C. bonduc. Inflammation was induced in rat paw by injecting 0.1 ml of carrageenan (1% w/v) in subplantar region of right hind paw. Inflammation induce...

rutting of hot mix asphalt pavements due to increased number of heavy vehicles, especially in tropical regions, causes several performance problems. large stone asphalt mixtures have more stiffness and shear resistance and so more rutting resistance compared to conventional mixtures. hence, using these mixtures in thick layers of hot mix asphalt pavements at tropical regions could be an appropr...

Determination of concentrations of sulfur compounds in different petroleum samples is a true analytical challenge. Only analytical procedures based on gas chromatography can meet the sensitivity and accuracy requirements dictated by up-to-date petroleum industry. The objective of this work is to develop the method for the quantifying of sulfur compounds in petroleum hydrocarbon streams. The opt...
