In this paper, we describe an industrial experience with the creation of a new product for collaboratively navigating and reviewing 3D engineering models, applied to the oil industry. Together with professional oil industry engineers from a large oil company, a team of HCI researchers performed task analysis and storyboards, designed, implemented and qualitatively evaluated a prototype that com...

Accidents involving rotating equipment in chemical, petrochemical, petroleum, and gas plants can result in damage to other process equipment and catalysts along with lost production. Conversely, process upsets, process instrumentation failure, or failures of other process equipment can result in damage to rotating equipment. An effective rotating equipment loss prevention program will be an int...

BACKGROUND Persian Gulf is an exposed and stressed area as a result of oil pollution and other fossil fuels containing PAHs. The susceptibility of using mudskippers to monitor marine pollution, like PAHs, points to the fact that mudskippers are able to accumulate and record the PAHs presented in the coastal environments. METHODS Polycyclic aromatic hydrocarbons (PAHs) were examined in the coa...
