Prevalence Ratio of Otitis Media with Effusion in Laryngopharyngeal Reflux
International Journal of Otolaryngology, 2019 Background Otitis media with effusion (OME) in adults is less prevalent than in the pediatric population but still causes considerable morbidity. It has been suggested that laryngopharyngeal reflux (LPR) may have a role in the aetiology of adult OME ...

Is a low sacral ratio associated with primary vesicoureteral reflux in children? [PDF]
Journal of Pediatric Nephrology, 2013 Introduction: The association of sacral anomalies with fecal incontinence and lower urinary tract dysfunction is known. The sacral ratio is proposed as a tool for evaluation of sacral development. The aim of this cross-sectional study was to evaluate the

On the Minimum Reflux Ratio in Multicomponent Distillation
Chemical engineering, 1967 著者らは、理論段数無限大のときの多成分系蒸留における末端組成の解析を行ない, 留出量および非分配成分の数を与えたときの最小還流比の有用な決定法を提出した。この解析の結果, ビンチポイントおよび原料供給段の組成の挙動が明らかになった。

GRAPHICAL CALCULATION METHOD FOR MINIMUM REFLUX RATIO IN AZEOTROPIC DISTILLATION
JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 1972 In an azeotropic distillation column, the rate of net flow and the composition of net flow for both stripping and rectifying sections can be calculated from the limiting conditions of the separation desired. The pinch points are dotted on the radial lines starting from the point of net flow composition by trial and error, and locus of the pinch points ...

Effect of reflux ratio on COD and nitrogen removals from coke plant wastewaters.
Water Science and Technology, 2010 A laboratory-scale anaerobic-anoxic-aerobic-moving bed biofilm reactor (A1-A2-O-MBBR) system was undertaken to treat coke plant wastewaters from two different factories (wastewater A and B). Wastewater B had higher BOD5/COD ratio and COD/TN ratio than wastewater A. The effects of reflux ratios on COD, TN and NH3-N removals were studied.
