NOx reduction for oxygen enriched combustion with two-stage tubular flame

Nihon Kikai Gakkai ronbunshu, 2016
Oxygen-enriched combustion is frequently applied to industrial furnaces for requiring high temperature heating. The burned gas temperature in the oxygen-enriched combustion becomes high because of a decrease of inert gas (nitrogen).

Chemical nonlinearities in relating intercontinental ozone pollution to anthropogenic emissions [PDF]

, 2009
Model studies typically estimate intercontinental influence on surface ozone by perturbing emissions from a source continent and diagnosing the ozone response in the receptor continent.

Managing sleep apnea: long-term outcomes from a comprehensive, patient-centered treatment care pathway

Frontiers in Sleep
IntroductionObstructive Sleep Apnea (OSA) is a chronic disease requiring life-long care, with clear benefit for those who remain adherent to positive airway pressure (PAP) therapy. Despite the efficacy of PAP, adherence to treatment has historically been

Ozone and alkyl nitrate formation from the Deepwater Horizon oil spill atmospheric emissions [PDF]

, 2012
Ozone (O3), alkyl nitrates (RONO2), and other photochemical products were formed in the atmosphere downwind from the Deepwater Horizon (DWH) oil spill by photochemical reactions of evaporating hydrocarbons with NOx (=NO+NO2) emissions from spill response

Decadal changes in summertime reactive oxidized nitrogen and surface ozone over the Southeast United States [PDF]

, 2018
Widespread efforts to abate ozone (O3) smog have significantly reduced emissions of nitrogen oxides (NOx) over the past 2 decades in the Southeast US, a place heavily influenced by both anthropogenic and biogenic emissions.

Patient satisfaction with a clinically integrated sleep apnea care model vs. the current sleep care paradigm

Frontiers in Sleep
IntroductionSleep apnea can have severe negative health effects, including cardiovascular diseases, metabolic disorders, and decreased quality of life. Continuous positive airway pressure (CPAP) therapy is highly effective and the gold standard treatment
