The crude oil prices as well as the effective exchange rate of the dollar are both time series and non -stationary as well. In this paper, we investigate the relationship between real effective exchange rate and crude oil prices by hybrid wavelet network. We use a simple Multi-layer Perceptron Neural Network (MLPNN) based wavelet decomposition to analyse the relatio nship between real effective...

crude oil is enriched in polycyclic aromatic hydrocarbons (pahs). many pah analogs have proved to potentially damage dna. dna damage can be assessed using various biomarkers to find out the degree of genotoxicity of pollutants following in vitro exposure. in this research the comet assay and micronucleus (mn) test were used to detect dna damages and cytogenetic changes following crude oil expos...

Oil from brebra (Millettia ferruginea) is the potential raw material for biodiesel production. The refining of crude oil requires a series of purification steps to produce quality biodiesel. The objective of the study was to produce refined oil from brebra seed for biodiesel production. Crude oil extraction was carried out using mechanical press and solvent extraction methods. Impurities of the...

Crude oil distillation (atmospheric distillation column with furnace) consumes about 50% of the energy required in oil refinery plant. To achieve further reduction of the energy required in oil refinery plants, it is required to investigate the crude oil distillation and to retrofit it for energy saving process. Recently, authors developed an innovative process design technology, self-heat recu...

Although planktonic protozoans are likely to interact with dispersed crude oil after a spill, protozoan-mediated processes affecting crude oil pollution in the sea are still not well known. Here, we present the first evidence of ingestion and defecation of physically or chemically dispersed crude oil droplets (1-86 μm in diameter) by heterotrophic dinoflagellates, major components of marine pla...

Based on monthly observations, I specify an econometric model capturing the driving forces behind the crude oil price series in recent years. A large set of covariates, such as supply and demand variables as well as futures market variables, is used to test the impact on the crude oil price. Current price movements are a result of scarce refining capacity and speculators betting on higher price...

Crude oil plays an increasingly significant role in world economic development and also in the generation of wealth since nearly two-thirds of the world’s energy consumption comes from crude oil and natural gas. Worldwide consumption of crude oil exceeds $500 billion—roughly 10% of US GDP and crude oil is also the world’s largest and most actively traded commodity, accounting for about 10% of t...
