Distributions of critical flux: modelling, experimental analysis and consequences for cross-flow membrane filtration [PDF]
, 2005 This paper discusses the distribution of critical flux (DCF) in cross flow filtration. These distributions are described here by a normal function with a mean critical flux and its standard deviation.

Calcium Channel Permeation: A Field in Flux [PDF]
The Journal of General Physiology, 1999 In 1955, Alan Hodgkin and Richard Keynes published a study whose intent was to answer a rather technical question, but whose result triggered the modern analysis of ion channel permeation ([Hodgkin and Keynes, 1955][1]). They aimed to determine whether the K+ fluxes in giant axons followed the “

A Comparison Study of Brine Desalination using Direct Contact and Air Gap Membrane Distillation
Journal of Engineering, 2019 Membrane distillation (MD) is a hopeful desalination technique for brine (salty) water. In this research, Direct Contact Membrane Distillation (DCMD) and Air Gap Membrane Distillation (AGMD) will be used. The sample used is from Shat Al –Arab water (TDS=

Complete Momentum-Balance Analysis of Permeate Flux for Ultrafiltration in Hollow-Fiber Modules [PDF]
, 2010 The predicting equations for the declines of transmembrane pressure and permeate flux in hollow-fiber ultrafilters were derived from the complete momentum balance with the consideration of the rate of momentum transfer by convection, instead of simply ...
