This study proposes a microfluidic system comprising channel and cylindrical hole for holding commercially available culture insert with collagen vitrigel membrane. Because the bottom surface of top are in same plane, flow medium can be directly applied to cells on surface. Additionally, is easily removable from various biological analyses standard protocol, making this accessible users who not...

the reported work is on the preparation and characterization of polyvinyl alcohol -g- polyacrylic acid (pva-g-paa)/ polybenzimidazole sulfone (pbis) cation exchange membrane used for the electro dialysis of sodium chloride solution. the polymer syrup has been prepared using the grafting method with the help of polyvinyl alcohol and polyacrylic acid in the presence of water solvent. the polymer ...

a membrane bioreactor (mbr) system based on a dead-end immersed hollow fiber membrane and filamentous fungus aspergillus oryzae were used for treatment of baker’s yeast wastewater. the fungus was adapted to the wastewater in the bioreactor for two weeks before starting the continuous process. average organic loading rate of 4.2 kg cod/m3.d was entered the bioreactor. mbr system was able to redu...

Abstract Membranes are used widely in engineering applications, including the porous membranes fuel cells and ventilation systems. In order to understand mechanical behavior of membrane, one should know loads acting on it, tension applied it during manufacturing process. This study describes a novel contact-based method measure pre-tension for such as membrane energy exchangers, where optical a...

* Corresponding author ([email protected]) Abstract Membrane computing is an emergent branch of natural computing, which has been extensively used to solve various NP-complete and intractable problems. In this paper, a bioinspired algorithm based on membrane computing (BIAMC) is proposed to solve the engineering design problem. BIAMC is designed with the framework and rules of a cell-like P ...
