Plant health index as an anomaly detection tool for oil refinery processes.

Early detection of significant abnormal changes is highly desirable for oil refinery processes, which consist of sophisticated unit operations handling hazardous and flammable inventories and operating at high temperature and pressure. Close monitoring and anomaly detection are vital for avoiding major accidents and losses and enable intervention before failure occurrence. A new big data analytics tool called Plant Health Index (PHI) is proposed in this work.

Preparation of Mesoporous Silica by Nonionic Surfactant Micelle-Templated Gelation of NaSiO and HSiF and Application as a Catalyst Carrier for the Partial Oxidation of CH.

Mesoporous silica (MSPN12) was prepared by nonionic surfactant micelle-templated gelation of sodium silicate (NaSiO) and fluorosilicic acid (HSiF) in aqueous solution, characterized by a range of instrumental techniques, and tested as a support for Ni and Rh catalysts in the partial oxidation of methane (POM). Calcined and sintered MSPN12 exhibited well-defined d-spacings (3.5-4.

Psychometric properties of the Korean version of the Short Post-Traumatic Stress Disorder Rating Interview (K-SPRINT).

Aims: The Short Post-traumatic Stress Disorder (PTSD) Rating Interview (SPRINT) is a validated, eight-item, brief global assessment scale for PTSD. This report investigated the psychometric properties of the Korean version of the SPRINT (K-SPRINT).

Methods: Eighty-seven PTSD patients, 47 other psychiatric patients, and 63 healthy control subjects were enrolled in the study.
