<abstract> <p>Vegetable oils are among the foodstuffs produced and consumed in abundance by population Burkina Faso. These edible nutrient sources for health. However, oxidation of is a phenomenon that leads to their degradation. Hence, objectives this study were determine antioxidants compounds, evaluate antioxidant activity vegetable Faso propose good manufacturing practices. Thus...
The purpose of this study was to determine the antibacterial activity of ten essential oils. The ten essential oils were tested on MRSA and MSSA from hospital patients using the disk diffusion (Kirby Bauer) method. Based on this study, all ten oils showed higher effectiveness inhibiting MRSA and MSSA growth than vancomycin, which is the currently used standard for treatment. Essential oils coul...
Crude oil contamination is one of the major environmental concerns and it has drawn interest from researchers and industries. Heavy oils contain 24-64% saturates and aromatics, 14-39% resins and 11-45% asphaltene. Resins and asphaltenes mainly consist of naphthenic aromatic hydrocarbons with alicyclic chains which are the hardest to degrade. Crude oil biodegradation process, with its minimal en...
Palm oil is the most consumed and traded vegetable oils in the EU and the world. Increasing non-food uses for vegetable oils in especially feedstock of biofuels in recent years have caused the price volatility to rise in both EU and global market. The most efficient pricing of crude palm oil (CPO) is to found on Bursa Malaysia (BMD), and it provides by far the world’s most liquid palm oil contr...
Abstract In this study, bimetallic catalysts based on transition metals CuFe 2 O 4 , CoFe and NiFe are proposed for catalyzing aquathermolysis reaction during steam-based EOR method to improve in-situ heavy oil upgrading. All upgrading experiments were carried out under a nitrogen atmosphere 24 h in 300-ml batch Parr reactor at 250 300 °C high pressure 35 75 bar, respectively. To evaluate the c...
Modern use of petroleum-derived oils as agricultural crop protectants dates back to the 1800s, but it was not until the latter half of the 20th century that advances in petroleum chemistry allowed substantial modification and diversification in their commercial applicability. In the 1880s, a kerosene–soap emulsion was used with some success against scales and aphids in citrus trees. The search ...
The Hebei Spirit oil spill (HSOS) in December 7, 2007 spilled approximately 10,900 tons of crude oil in about 10 km off the Taean coasts in South Korea. We first summarize and overview, in the present study, the current status of environmental and ecological effects of the HSOS focusing on i) pollution status for surrounding environment (water, sediment, and porewater), ii) biological effects o...
Abstract This essay considers the multiscalar manifestations of loss and destruction through material-semiotic figure “spent earth,” a toxic waste by-product generated by industrial bleaching crude oils into edible oils. Drawing on two distinct encounters with spent earth in Indonesian palm oil sector, reflects substance's unevenly distributed effects across peoples, places, generations; its as...
