The treatment performance and spatial microbial community structure of three parallel denitrifying biological filters (DNBFs) operated with methanol, ethanol and acetate, respectively, were explored. The acetate-fed DNBF presented the highest denitrification rate and NOx-N (NO2-N and NO3-N) removal efficiency, while the methanol-fed DNBF showed the lowest carbon consumption and NOx-N removal ef...

STUDY OBJECTIVES In maxillary nosocomial sinusitis (MNS) related to severe sepsis, nitric oxide (NO) concentration in the maxillary sinuses is drastically reduced secondarily to a downregulation of type-2 NO synthase. NO plays a major role in nonspecific immune defense of sinuses. We therefore aimed to study maxillary NO concentration during the treatment of MNS with drainage, daily lavage, and...

Solid-state electrochemical sensors using yttria-stabilized zirconia (YSZ) and oxide sensing electrode (SE) were fabricated and examined for NOx detection at high temperatures. Among various single-oxide SEs examined, NiQSE for the mixed-potential-type NOx sensor was found to exhibit rather high sensitivity to N@ even in the high temperature range of 800900°C. This sensor showed quicker respons...
