The aim of this study is to investigate a data mining approach to help assess consequences of oil spills in the maritime environment. The approach under investigation is based on the visual detection of suspected oil droplets in the water column adjacent to the Deepwater Horizon oil spill. Our method detects particles in the water, classifies them and provides an interface for the visual displa...

The objectives of the present study were to evaluate and compare the antimicrobial activities of olive oil and vinegar against Salmonella and Escherichia coli. The spread plate method was used to determine the growth of Salmonella and Escherichia coli. The concentration of preservatives used for inhibition of Salmonella and Escherichia coli was determined by using minimum inhibitory concentrati...

Nonionic surfactant-stabilised oil-in-water emulsions offer a potentially useful vehicle for transporting heavy crude oils from oilfields to refineries or distribution terminals. Prior to refining, separation of the oil from the emulsion is necessary. Previous studies have suggested that heating the emulsion is sufficient for destabilisation and recovery of the oil. The present work examines th...

In the present work, a comprehensive study was made on the analysis of chemical composition of essential oil and antibacterial activity from the leaves of Ajuga bracteosa. The essential oil was extracted by Cleavenger type apparatus and analyzed by GC-MS. The main components present in the essential oil of leaves are Limonene, α-humulene, β-Myrcene, Elemol, Camphene, βCaryophellene, α-phellendr...

Essential oil of Juniperus oxycedrus growing in Algeria was obtained by steam distillation extraction method. The oil was analysed by capillary columns (non-polar DB5 and HP-chiral-20B) using gas chromatography with flame ionization and mass spectrometric detections. The compounds were identified according to their retention indices and mass spectra (EI, 70 eV). The oil contained α-pinene (36.7...

In November 2014, OPEC announced a new strategy geared towards improving its market share. Oil-market analysts interpreted this as an attempt to squeeze higher-cost producers including US shale oil out of the market. Over the next year, crude oil prices crashed, with large repercussions for the global economy. We present a simple equilibrium model that explains the fundamental market factors th...

Essential oils present a fine antibacterial performance against a variety of bacteria. The main component of the cinnamon oil was eugenol (75.52%). In this study, the goal was to evaluate the antimicrobial activity and reveal bactericidal mechanism of cinnamon oil. Firstly, the minimum inhibitory concentration (MIC) and the minimum bactericide concentration (MBC) of cinnamon oil were tested. Th...

The seeds of the wild Prunus armeniaca L. (wild Apricot) from the Garhwal Region of Uttarakhand (India) was analysed for its proximate compositions and the physico-chemical characteristics of the oil. The elements present in seed oil were also determined which reflected that apricot is rich in Phosphorous, Calcium, Magnesium, Iron and Copper which makes it suitable for edible and commercial oil...

Omega-3 polyunsaturated fatty acids are essential fatty acids offering multiple health benefits. They form an integral part of cell membrane and are indispensable for normal metabolism. Fish oil and flaxseed oil are among few dietary sources of these fatty acids. In present investigation, hepatoprotective potential of omega-3 fatty acids in the form of flaxseed oil and fish oil was assessed aga...

Joint Inversion of Fracture Model Properties for CO2 Storage Monitoring or Oil Recovery History Matching — For oil recovery or CO2 storage, “reservoirs” are commonly used to designate geological structures where oil can be found or CO2 can be stored. All reservoirs present a heterogeneity in terms of rock type and properties (such as porosity and permeability). In addition, some of these reserv...
