Membrane filtration, especially based on the size exclusion phenomenon, has long been established due to its abilities to addressing the growing demands of the clean water of the world’s population. However, widespread applications of the membranes face several challenges including chemical vulnerability, thermal deterioration, and biological degradation of the membranes that transpire while re...

rewriting systems on multisets (ARMS) are a simple construct in the context of Computational living systems, constituting a class of P systems that have been devised for modelling systems dynamics, with the belief that [177]: Environment + Computational living systems = Computation in agreement with the vision of living beings as computing entities whose computation purpose is keeping themselve...

endoplasmic reticulum has a critical role in the synthesis and folding of secretory and membrane proteins. high accumulation of proteins in er activates the unfolded protein response and glucose regulated protein 78 or gpr78 plays an essential role in this pathway.  unfolded protein response is activated in cancerous cells due to their adverse condition to survive and it has been shown that grp...

The characterizations of vegetable oil wastewater (VOW) are unpleasant odor, dark color, and high organic contents, including large amounts of oil and grease (O&G), chemical oxygen demand (COD), fatty acids and lipids. Therefore, VOWs should be treated efficiently to avoid the environment pollution. The aim of present study was the investigation of VOW biological treatment using membrane biorea...
