The 2010 Deepwater Horizon (DWH) catastrophe had considerable impact on the ∼ 50 km long sandy beach system located along the Alabama shoreline. We present a four-year dataset to characterize the temporal evolution of various polycyclic aromatic hydrocarbons (PAHs) and their alkylated homologs trapped in the residual oil buried along the shoreline. Field samples analyzed include the first arriv...

Olive oil mill wastewaters (OOMW) represent a significant environmental problem especially in the Mediterranean, the main olive oil production region in the world. Characterization of OOMW is carried out by determination of various parameters, such as BOD5, COD and content of total phenols. The aim of this paper is to evaluate existing (physical, biological etc.) and emerging technologies for a...

Aquilegia vulgaris seed oil contains high levels of the rare fatty acid columbinic acid (18:3 Delta(5,9,12)), which is unusual in having the double bond at the Delta(5) carbon in the trans configuration. Columbinic acid was found to be a seed-specific fatty acid not only present in the storage oil but also in membrane lipids. Several putative gene fragments have been isolated from plant RNA wit...

Effective tribofilms are desirable to protect mechanical systems. In the present research, we investigated the formation of a tribofilm through the use of α-ZrP (Zr(HPO4)2 ̈H2O) as an additive. Experiments were conducted on a base oil where 0.2 wt% of the additive was used. Experimental results showed a 50% reduction in friction and a 30% reduction in wear when compared to the base oil containin...

This study focused on the characterization of olive oil produced in the Kairouan area (center of Tunisia) in order to install Protected Geographical Indication (PGI). Thus, chlorophylls, carotenoids, phenols and tocopherols contents, fatty acid composition, quality parameters and organoleptic profile were determined on 90 samples of extra virgin olive oil extracted from two different varieties ...

Biosurfactant production using Candida bombicola ATCC 22214, its characterization and potential applications in enhancing oil recovery were studied at laboratory scale. The seed media and the production media were standardized for optimal growth and biosurfactant production. The production media were tested with different carbon sources: glucose (2%w/v) and corn oil (10%v/v) added separately or...

Optimal climate policy is studied in a Ramsey growth model with exhaustible oil reserves, an infinitely elastic supply of renewables, stock-dependent oil extraction costs and convex climate damages. We concentrate on economies with an initial capital stock below that of the steady state of the carbon-free economy and the initial cost of oil (extraction cost plus scarcity rent and social cost of...
