In this paper, we propose novel decision support system (DSS) named OPEC-DSS to support OPEC’s decisions on oil production level. OPEC-DSS is based on two important factors in oil prices; the first is OPEC oil production level (OPEC-PL) and the second is USA oil imports level (USA-IL). The OPEC-DSS support the analysers and decision-makers in three following issues: 1) OPEC-DSS can propose the ...

Automatic detection and monitoring of oil spills and illegal oil discharges is of fundamental importance in ensuring compliance with marine legislation and protection of the coastal environments, which are under considerable threat from intentional or accidental oil spills, uncontrolled sewage and wastewater discharged. In this paper the level set based image segmentation was evaluated for the ...

A membrane inlet mass spectrometry (MIMS) system has been used for detection and analysis of two types of North Sea crude oil. The system was installed on-field on the Flotta Oil Terminal (Orkney, UK). It consisted of a quadrupole mass spectrometer (QMS) connected to the capillary probe with a silicone-based membrane. The produced mass spectra and calibration plots from the MIMS instrument show...

salvia is a valuable medicinal and aromatic genus belongs to the lamiaceae family. in this study, morphological traits and essential oil content were used for the estimate of variability and to determine the relationship among different species of salvia including s. syriaca (5 ecotypes), s. virgate (8 ecotypes), s. reuterana (6 ecotypes) and s. multicaulis (6 ecotypes) collected from the south...

Ecological disasters resulting from oil spills have created a great need to find more efficient materials for oil spill cleanup. This research highlights the use of a novel macroporous polymeric material based on butyl rubber (BR) as a sorbent in an oil spill cleanup. The sorption capacity of BR for crude oil and petroleum products is 15-23 g g(-1) as compared to the value of 10-16 g g(-1) obta...

In this study, the growth of sixty-one bacterial strains in crude oil were determined spectrophotometrically at 620 nm. Pseudomonas aeruginosa G1, Pseudomonas fluorescens G6, Pseudomonas stutzeri G11 and Pseudomonas putida G15 were chosen for the study based on the efficiency of crude oil utilisation. At 1% (v/v) crude oil concentration, P. stutzeri G11 strain degraded a maximum of 69%. The per...

BACKGROUND Nonomuraea dietziae is a promising microorganism to mediate the region-specific monooxygenation reaction of cyclosporine A (CsA). The main product [(4'-OH)MeLeu]4-CsA possesses high anti-HIV/HCV and hair growth-stimulating activities while avoiding the immunosuppressive effect of CsA. However, the low conversion efficiency restricts the clinical application. In this study, the produc...
