Enrichment of AOB and NOB Population by Applying a BABE Reactor in an Activated Sludge Pilot Plant.

This paper deals with the effect of a bioaugmentation batch enhanced (BABE) reactor implementation in a biological nutrient removal pilot plant on the populations of ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB). The results of fluorescence in situ hybridization (FISH) technique showed that AOB and NOB populations were significantly enhanced, from 4 to 8% and from 2 to 9%, respectively, as a result of the BABE reactor implementation. Regarding AOB, the percentage of Nitrosomonas oligotropha was mainly increased (3 to 6%).

Impact of a program to improve pain management in an emergency department.

The objective of this study is to assess the impact of various actions in the management of pain in a pediatric hospital emergency department. This is an observational study, preaction (phase 1) and postaction (phase 2), with two cohorts of patients diagnosed with abdominal pain, chest pain, and severe headache. Between the two phases, various actions were carried out (distribution of pain assessment scales and a new guide for the management of pain, and the holding of clinical training sessions).
