Complex refractive index, single scattering albedo, and mass absorption coefficient of secondary organic aerosols generated from oxidation of biogenic and anthropogenic precursors [PDF]

, 2019
Refractive index and optical properties of biogenic and anthropogenic secondary organic aerosol (SOA) particles were investigated. Aerosol precursors, namely longifolene, α-pinene, 1-methylnaphthalene, phenol, and toluene were oxidized in a Teflon ...

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).

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

Atmospheric nitrogen oxides (NO and NO2) at Dome C, East Antarctica, during the OPALE campaign [PDF]

, 2014
Mixing ratios of the atmospheric nitrogen oxides NO and NO2 were measured as part of the OPALE (Oxidant Production in Antarctic Lands & Export) campaign at Dome C, East Antarctica (75.1 degrees S, 123.3 degrees E, 3233 m), during December 2011 to January

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

Evaluation of simulated O-3 production efficiency during the KORUS-AQ campaign: Implications for anthropogenic NOx emissions in Korea [PDF]

, 2019
We examine O3 production and its sensitivity to precursor gases and boundary layer mixing in Korea by using a 3-D global chemistry transport model and extensive observations during the KORea-US cooperative Air Quality field study in Korea, which occurred
