Characterization of ultrafiltration membranes by tracer's retention:Comparison of methods sensitivity and reproducibility [PDF]

open access: yes, 2010
Previous studies have shown that the absolute membrane cut-off and the value quoted by the manufacturers may be very different because of differences in methodologies and testing conditions.

Model selection and model averaging on mortality of upper gastrointestinal bleed patients [PDF]

open access: yes, 2018
Model Selection (MS) is known to produce uncertainty into model-building process. Besides that, the process of MS is complex and time consuming. Therefore, Model Averaging (MA) had been proposed as an alternative to overcome the issues.

Behaviours of natural organic matter in membrane filtration for surface water treatment : a review [PDF]

open access: yes, 2006
Membrane application in surface water treatment provides many advantages over conventional treatment. However, this effort is hampered by the fouling issue, which restricts its widespread application due to increases in hydraulic resistances, operational
