<p>The <span>performance of every electrical system depends on the different devices especially transformers. Petroleum-based mineral oil is widely used for insulation and cooling purpose. The disadvantage its low biodegradability a major threat to ecosystem due poor oxidative stability. To remedy drawbacks, focus alternative fluids that can replace traditional oil. Alternative liqu...

Oil spills and petroleum based pollutions are very common which cause a potential threat to both terrestrial as well as aquatic life. Bioremediation has become an alternative way to remedy. These microorganisms can degrade a wide range of target constituents present in oil sludge. An ability to isolate high numbers of certain oil degrading microorganisms from an environment is commonly taken as...

The buried China-Russia Crude Oil Pipeline (CRCOP) across the permafrost-associated cold ecosystem in northeastern China carries a risk of contamination to the deep active layers and upper permafrost in case of accidental rupture of the embedded pipeline or migration of oil spills. As many soil microbes are capable of degrading petroleum, knowledge about the intrinsic degraders and the microbia...

The presence and abundance of non-indigenous, and/or harmful or toxic dinoflagellate species in ballast sediments is examined for 65 cargo ships visiting ports on the East coast of Canada, as part of the Canadian Aquatic Invasive Species Network (CAISN). Ships visiting several ports in the provinces of Quebec, New Brunswick and Nova Scotia were sampled during three summers (2007, 2008, 2009). T...
