Research ArticleOpen accessPhrase in the titleMutagenic Screening of Crude Oil Fractions Using Modified Ames Test and Allium cepa (Linn) AssayOlufunsho Awodele, Alade Akintonwa, Sunday O. Olayemi et al.Problem statement: Crude oil which may be broadly characterized as paraffinic or naphthenic is a complex mixture of alkanes, cycloalkanes and aromatic hydrocarbons. About 500,000 workers are employed in crude oil exploration and production worldwide. There have been reports of occupational exposure during drilling, pumping and transportation of crude oil, including maintenance of equipment used for these processes. Thus, skin … …American Journal of Pharmacology and Toxicology, Vol. 5, Issue 1 · 31 Jan 2010 · 8,629 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleEffects of Crude Oil and Spent Oil on Clarias garipinus: A Typical Marine FishA. M. Gbadebo, A. M. Taiwo, O. B. OlaProblem statement: Petroleum hydrocarbon and petroleum residue (i.e., spent oil) remains the foremost pollutants to the fish communities in various aquatic media-ponds, streams, rivers, creeks, coastal and marine environments through indiscriminate disposal of oil contaminated drilling muds, cutting and oil spillages. Approach: Also, the spent oil enters into aquatic media through run-off following unguided disposal. Both the petroleum hydrocarbon and … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 7,467 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titlePrice Volatility of Grains: Relationship with Crude Oil Price Using CCC-Multivariate GARCH ModelAreerat Todsadee, Hiroshi Kameyama, Shoichi ItoAgricultural commodities prices have increased and become significantly more volatile during the past few years periods. The high agricultural commodity prices in recent years have raised the question of whether or not volatility is increasing and leading to more frequent extreme price swings. It is very important to quantify price variability of agricultural products. This paper measures the volatility of … …American Journal of Economics and Business Administration, Vol. 6, Issue 4 · 2 Jan 2015 · 6,640 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleDAILY CRUDE OIL PRICE FORECASTING MODEL USING ARIMA, GENERALIZED AUTOREGRESSIVE CONDITIONAL HETEROSCEDASTIC AND SUPPORT VECTOR MACHINESRana Abdullah Ahmed, Ani Bin ShabriCrude oil price forecasting is gaining increased interest globally. This interest is due mainly to the economic value attached to the product. For this reason, new forecasting methods are proposed in the literature. This paper proposes a novel technique for forecasting crude oil price based on Support Vector Machines (SVM). The study adopts the data on crude oil price of … …American Journal of Applied Sciences, Vol. 11, Issue 3 · 11 Jan 2014 · 8,725 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleComposition-Explicit Distillation Curves of Waste Lubricant Oils and Resourced Crude Oil: A Diagnostic for Re-Refining and EvaluationLisa Starkey Ott, Beverly L. Smith, Thomas J. BrunoProblem statement: We have recently introduced several important improvements in the measurement of distillation curves for complex fluids. The modifications include a composition-explicit data channel for each distillate fraction and temperature measurements that are true thermodynamic state points that can be modeled with an equation of state. The composition-explicit information is achieved with a sampling approach that allows precise qualitative … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 8,101 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleA screen for Benzo(a)pyrene in Fish Samples From Crude Oil Polluted EnvironmentsChimezie Anyakora, Mohsen Arbabi, Herbert CokerSeveral studies have shown that exposure to Benzo(a)pyrene increases the risk of cancer. In this study several fish samples from Niger the Delta region of Nigeria were screened for the presence of Benzo(a)pyrene. The study was carried out using Gas chromatograph coupled to a mass spectrometry detector. Benzo(a)pyrenes in the samples were identified through both retention time match with authentic … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 6,766 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleImprovements on Semi Critical Assisted-Solvent Extraction of Biocrude Oil from Spirogyra. sp Macro AlgaeTulio Chavez-Gil, Hany F. Sobhi, Alexis Pacheco-LaracuenteHere, we report on an improved chemical method to extract hydrocarbons (CH) and Fatty Acid Methyl Esters (FAME) from wild green macro algae, which is higher than that carried out with conventional Soxhlet (Sx) and similar to that of Subcritical (SbC) or supercritical fluid (SCE) extraction methods. Crude oil plus residual biomass gave combined calorific values of 49.05 MJ/kg in … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 2 · 18 Apr 2018 · 10,083 accessesView PDF Cite
