Alteration and release of aliphatic compounds by the polychaete Nereis virens (Sars) experimentally fed with hydrocarbons [PDF]
, 2001 In the laboratory, marine worms were fed with a mixture of algae and several aliphatic hydrocarbons for 15 days. After ingestion by the worms, 34.9% of hydrocarbons are found in the faeces and only 3.1% accumulated in the gut.

A five year record of high-frequency in situ measurements of non-methane hydrocarbons at Mace Head, Ireland [PDF]
, 2011 Continuous high-frequency in situ measurements of a range of non-methane hydrocarbons have been made at Mace Head since January 2005. Mace Head is a background Northern Hemispheric site situated on the eastern edge of the Atlantic. Five year measurements

Cuticular hydrocarbons for the identification and geographic assignment of empty puparia of forensically important flies. [PDF]
, 2022 Research in social insects has shown that hydrocarbons on their cuticle are species-specific. This has also been proven for Diptera and is a promising tool for identifying important fly taxa in Forensic Entomology.

New model for standpipe pressure prediction while drilling using Group Method of Data Handling
Petroleum, 2022 The continuous evaluation of the measured Stand Pipe Pressure (SPP) against a modeled SPP value in real-time involves the automatic detection of undesirable drilling events such as drill string washouts and mud pump failures.

Recycling of solvent used in a solvent extraction of petroleum hydrocarbons contaminated soil. [PDF]
, 2011 The application of water washing technology for recycling an organic composite solvent consisting of hexane and pentane (4:1; TU-A solvent) was investigated for extracting total petroleum hydrocarbons (TPH) from contaminated soil. The effects of water

Atomic displacements due to spin–spin repulsion in conjugated alternant hydrocarbons [PDF]
, 2013 We develop a theoretical model to account for the spin-induced atomic displacements in conjugated alternant hydrocarbons. It appears to be responsible for an enlargement of the distance between pairs of atoms separated by two atoms and located at the end

Fate of polycyclic aromatic hydrocarbons during composting of lagooning sewage sludge [PDF]
, 2005 The fate of 16 polycyclic aromatic hydrocarbons (PAHs), targeted by the USEPA agency, has been investigated during composting of lagooning sludge. Composting shows efficient decrease of the content and the bioavailability of each PAH.
