Employing gas chromatography-mass spectrometry (GC-MS), a complete collection of 509 gas samples provided volatile organic compounds (VOCs) for training and testing a Multilayer Perceptron Network (MPN) model for discrimination. Intraluminal and exhaled gas samples, with distinct VOC profiles, yielded an area under the curve (AUC) greater than…[Leer más]

Dimpled surface piers, in comparison to cylindrical piers, minimize the disruption caused by turbulent flow and induce a miniaturized, swirling flow. The lower downstream lateral velocity behind the dimpled pier reduces drag, energy loss, and subsequently lessens scour.

By examining two municipal water plants and a pilot facility in Jinan,…[Leer más]
