The biological nitrogen removal process in wastewater treatment inevitably produces nitrous oxide (NO), a potent greenhouse gas. Coarse bubble mixing is widely employed in wastewater treatment processes to mix anoxic tanks; however, its impacts on NO emissions are rarely reported. This study investigates the effects of coarse bubble mixing on NO emissions in a pilot-scale mainstream nitrite shunt reactor over a 50-day steady-state period.

- Cyanobacteria of the genus contribute new nitrogen to nutrient-poor marine ecosystems, but their role as a food source is not well understood.
- In a lab study, researchers found that the predatory crown-of-thorns starfish (CoTS) larvae feed exclusively on this cyanobacteria during their larval phase.
- The presence of cyanobacteria in CoTS larvae suggests that increased blooms may contribute to rising populations of CoTS, which have been harmful to coral reefs in recent decades.
Anaerobic oxidation of methane (AOM) is a microbial process of importance in the global carbon cycle. AOM is predominantly mediated by anaerobic methanotrophic archaea (ANME), the physiology of which is still poorly understood. Here we present a new addition to the current physiological understanding of ANME by examining, for the first time, the biochemical and redox-active properties of the extracellular polymeric substances (EPS) of an ANME enrichment culture.

Methods: A retrospective review of patients treated with SBRT to HN sites from 2012 to 2020 was conducted. Treatment indications included the following: oligometastases, oligoprogression, and control a dominant area of progression (DAP).

Purpose: Advanced practice (AP) in radiation therapy (RT) is being implemented around the globe. In an effort to advance the understanding of the similarities and differences in APRT roles in Ontario, Canada, a community of practice (CoP) sought ways to provide quantitative data on the nature of APRT clinical activities and the frequency with which these activities were being executed.
Methods: In 2017, a consensus building project involving 20 APRTs and 14 radiation therapy (RT) department managers in Ontario was completed to establish a mechanism to quantify APRTs' clinical impact.
