Petrol 18 946: Downhole failures revealed through ontology engineering

Analysis of a petrol plume over England : 18 - 19

Objectives—About 7000 tonnes of unleaded petrol were discharged into the English Channel after a tanker collision oV Ostend on Saturday 18 January 1997. The petrol evaporated and the vapour plume was carried across the central part of England to Wales, resulting in reports of unidentified odours, and irritation of the eyes, skin, and upper respiratory tract. This work uses this incident to show...

RDF Ontology (Re-)Engineering through Large-scale Data Mining

As Linked Open Data originates from various sources, leveraging well-defined ontologies aids integration. However, oftentimes the utilization of RDF vocabularies by data publishers differs from the intended application envisioned by ontology engineers. Especially in largescale datasets as presented in the Billion Triple Challenge a significant divergence between vocabulary specification and usa...

Lignans are phytoestrogens that are metabolized by the gut microbiota to enterodiol and enterolactone, the main biologically active enterolignans. Substantial interindividual variation in plasma concentration and urinary excretion of enterolignans has been reported, this being determined, at least in part, by the intake of lignan precursors, the gut microbiota, and the host’s phase 2 conjugatin...

Primordial germ cells (PGCs) form at the posterior pole of the Drosophila embryo, and then migrate to their final destination in the gonad where they will produce eggs or sperm. Studies of the different stages in this process, including assembly of germ plasm in the oocyte during oogenesis, specification of a subset of syncytial embryonic nuclei as PGCs, and migration, have been informed by gen...
