This study aims to elucidate the underlying mechanism of association between heat characteristics and influencing factors provide theoretical guidance for increasing safety economics during waxy crude oil storage. Physical mathematical models with numerical approaches represent static cooling are established. Based on simulations, effect wall temperature velocity distribution is mainly confined...

BACKGROUND Adjuvants can improve pesticide application efficiency and effectiveness. However, quantifications of the adjuvant-amended pesticide droplet actions on foliage, which could affect application efficiencies, are largely unknown. RESULTS Droplet evaporation rates and spread on waxy or hairy leaves varied greatly with the adjuvant types tested. On waxy leaves, the wetted areas of dropl...

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...

A molecule-based characterization methodology was developed for correlation and prediction of assays and properties for crude oil and petroleum fractions. From readily accessible crude oil, the assay data such as distillation curve, API gravity, and PNA contents, identifies an optimal set of chemical compositions of model hydrocarbon molecules that were designed to mimic measurable physical and...

Crude oil is one of the most necessitated worldwide required commodities. Any slight fluctuation in crude oil prices can have both direct and indirect influence on the economy of the countries. The unpredictability of crude oil prices forced many companies away from the competition and it influence the stock market and many other macroeconomic variables (inflation, GDP, Import bill etc). Crude ...
