A More Aggressive Approach is Needed for Gas Separation Membrane Development

A Narrative Review of Norovirus Gastroenteritis: More Global Attention Is Needed

Noroviruses (NoVs), an important pathogenic agent of foodborne illness, lead to acute and chronic gastroenteritis in humans of all ages and to travelers’ diarrhea. Many genotypes exist in nature; GII.4 is widely known as the most predominant. Outbreaks mostly occur in semi-closed settings. Although the disease is self-limited to person, many cases have resulted in death, which has raised more c...

Membrane Technology for Gas Separation

Membrane technology applied to the separation of gaseous mixtures competes with conventional unit operations (e.g., distillation, absorption, adsorption) on the basis of overall economics, safety, environmental and technical aspects. Since the first industrial installations for hydrogen separation in the early eighties, significant improvements in membrane quality have been achieved in air sepa...

An Effective Iterative Algorithm for Modeling of Multicomponent Gas Separation in a Countercurrent Membrane Permeator

 A model is developed for separation of multicomponent gas mixtures in a countercurrent hollow fiber membrane module. While the model’s solution in countercurrent module usually involves in a time consuming iterative procedure, a proper initial guess is proposed for beginning the calculation and a simple procedure is introduced for correcting the guesses, hereby the CPU time is decreased ess...
