Effect of operation factors on permeate fluxes in pervaporation.

KAGAKU KOGAKU RONBUNSHU, 1989
(CH3) 3NH+にカチオン置換したNAFION®-125膜を用いてエタノール水溶液の透過実験を行い, 透過流束への操作因子の影響について検討した.実験条件は, 1次側試料溶液中の水のモル分率=0.0-1.0, 1次側圧力=101-1082kPa, 2次側圧力=0.1-20kPa, 温度 =303-343Kであった.透過成分間および膜と透過成分間の相互作用を表す透過流束の補正係数を用いて透過挙動を評価した.実験結果は以下のように要約される.透過流束は1次側組成に強く影響した.補正係数は組成に対して非線形に変化した.

Feasibility and Safety of Somato‐Cognitive Coordination Therapy for Cerebellar Ataxia Following Pediatric Brain Tumor Treatment

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cerebellar ataxia after pediatric brain tumor treatment can cause persistent gait, balance, and speech impairment, yet no established rehabilitation strategy exists. Somato‐cognitive coordination therapy (SCCT) is a virtual reality–guided intervention designed to promote sensorimotor integration through visually constrained reaching

Transient permeate flux analysis: model validation

Water Supply, 2001
An extended model integrating several particle back-transport theories has been proposed by Sethi and Wiesner to predict transient permeate flux as a function of operational parameters for constant permeate flux (CF) and constant transmembrane pressure (CP) cross-flow regimes.
