Many organizations interested in renewable, domestic energy have switched from petroleum diesel to biodiesel blends for use in transportation and heavy-duty equipment. Although considerable evidence exists on the negative health effects of petroleum diesel exhaust exposures in occupational settings, there has been little research examining biodiesel exposures. Working collaboratively with a loc...

OBJECTIVE Although petroleum products are useful chemical compounds which form an integral part of our modern technology, they have been reported to cause deleterious effect on health following their inhalation. Petroleum hydrocarbons-dependent health hazards and their mechanisms have been associated with the routes of administration. This study, therefore, aimed at the isolation and chemical c...

Electrospun non-woven poly(ε-caprolactone) (PCL) microfiber meshes are described as biodegradable, mechanically robust, and reusable polymeric oil sorbents capable of selectively retrieving oil from simulated oil spills in both fresh and seawater scenarios. Hydrophobic PCL meshes have >99.5% (oil over water) oil selectivity and oil absorption capacities of ~10 grams of oil per gram of sorbent m...

Microbial enhanced oil recovery: literature survey http://www.clw.csiro.au/publications/science/2008/ WFO-MicrobialOilRecovery.pdf This report is well referenced and contains some general information on enhanced recovery techniques and biosurfactants. Oil spill: Wikipedia http://en.wikipedia.org/wiki/Oil_spill This Wikipedia entry is a good starting point for information on oil spills. Parts of...

An improved procedure for controlling the acidity ofphosphate esters is described. In the presence of water phosphate esters undergo hydrolysis which increases the acidity of the jluid and eventually lea& to fluid degradation. Currently this problem is addressed through the use of acid adsorbing andor neutralizing agents such as Fuller's earth or activated alumina. Bese agents neutralize the ac...

For almost a century, various predictions have been made that the human race was imminently going to run out of available petroleum. The passing of time has proven all those predictions to have been utterly wrong. It is pointed out here how all such predictions have depended fundamentally upon an archaic hypothesis from the 18th century that petroleum somehow (miraculously) evolved from biologi...

<p>Vegetable oils have been an alternative to mineral oil for oil-immersed transformers due concern on less flammable, environmental-friendly, biodegradable, and sustainable resources of petroleum-based insulating oil. This paper presents the effect electrical discharges (200 up 1000 discharges) under 50 Hz inhomogeneous electric field properties (acidity, water content, breakdown voltage...
