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

Water Environment Research, 2015
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 analogy between absorptive optical bistability (AOB) and equilibrium thermodynamics

Optics Communications, 1988
Abstract It is shown that if one neglects quantum fluctuations, the Fokker-Planck equation of AOB satisfies the conditions of detailed belancing, and then draws a parallel between the potential function contained in the stationary solution of this equation and the “Gibbs' free energy” G ∽ in equilibrium thermodynamics.

The different responses of AOA and AOB communities to irrigation systems in the semi-arid region of Northeast China [PDF]

Frontiers in Microbiology
Ammonia oxidation is the rate-limiting step in nitrification and the key step in the nitrogen (N) cycle. Most soil nutrients and biological indicators are extremely sensitive to irrigation systems, from the perspective of improving soil fertility and ...

[Inhibiting Form of Ammonium to AOB and Inhibiting Rule].

Huan jing ke xue= Huanjing kexue, 2016
The inhibiting form and rule of ammonium to ammonia oxidation bacteria ( AOB) were investigated through a series of batch experiments using biofilm reactor,in which the reaction conditions were controlled to 30 degrees C, HRT 4.76 h, ORP 100 mV. The results showed that when the AOB activity was half-inhibited at an ammonia nitrogen concentration of 2 ...

Akutno oštećenje bubrežne (AOB) funkcije. Poseban osvrt na AOB u sepsi i malnutriciji kao nedovoljno prepoznat problem

Liječnički vjesnik : glasilo Hrvatskog liječničkog zbora. Suplement, 2011
Akutno bubrežno oštećenje funkcije (AOBF) je ozbiljna komplikacija sepse. Uzrok je produljene hospitalizacije i povećanih troškova njege i liječenja. Malnutricija je čest problem, nedovoljno prepoznat, koji utječe na ishod i oporavak od bolesti. Od ranije prisutna kronična bubrežna bolest povećava rizik od razvoja AOBF, a rizik smrtnosti udružen je s ...

Simulated distribution nitrification: Nitrification Index evaluation and viable AOB

Journal AWWA, 2013
Lab‐scale reactors were used to evaluate the impact of simultaneously increasing temporal influent monochloramine (NH2Cl) concentrations (0.0 to 3.2 mg/L Cl2) and chlorine‐to‐nitrogen mass ratios (0:1 to 3.2:1) on nitrification, allowing evaluation of the recently proposed Nitrification Index (NI) for chloraminated drinking water distribution system ...

Manipulation of DNA damage checkpoint signaling in cancer cells by antioxidant biofactor (AOB)

Food Funct., 2013
Antioxidant biofactor (AOB) is one of the fermented grain food supplements commercially available in Japan and other countries. Herein, we investigated the effect of AOB on the UVC (254 nm) induced DNA damage in A549 cells. Both distilled water and MeOH extracts of AOB did not show any significant cell toxicity.

Phenols in anaerobic digestion processes and inhibition of ammonia oxidising bacteria (AOB) in soil

Science of The Total Environment, 2006
This study focuses on the presence of phenols in digestate from seven Swedish large-scale anaerobic digestion processes and their impact on the activity of ammonia oxidising bacteria (AOB) in soil. In addition, the importance of feedstock composition and phenol degradation capacity for the occurrence of phenols in the digestate was investigated in the ...

Low AOB Component Loads Derivation to Implement MH-60R HUMS

Proceedings of the Vertical Flight Society 76th Annual Forum, 2020
Presently the fatigue lives of MH-60R dynamic components and airframe are based on a usage spectrum developed using pilot surveys. In order to better define the usage spectrum and to extend component and airframe fatigue life, the Health & Usage Spectrum (HUMS) System was installed on the U.S. Navy MH- 60R Rotorcraft.

Approach Wood AOB, Fife: Archaeological Mitigation Data Structure Report

2022
The study area comprised a 30m by 20m rectangular area orientated on its long axis NE to SW with a 10m by 10m area in the W corner omitted. This area encompassed the conjectured footprint of the Auxiliary Operations Bunker (AOB) (from what could be discerned from visible surface elements of the AOB), the location of the stump of the transmitter tree ...
