A bstract Recently, an effective membrane theory was proposed that describes the “hydrodynamic” regime of entanglement dynamics for general chaotic systems. Motivated by new bit threads formulation holographic entropy, given in terms a convex optimization problem based on flow maximization, or equivalently tight packing threads, we reformulate as max proving flow-min cut theorem. In context hol...

membrane technology is used to separate water or solvents from salts or pollutants. this technique could be used for water treatment. for using of polyether sulfone (pes) hollow fiber membranes in water treatment processes, the pes hollow fiber membranes were prepared by dry-wet spinning method and heated in an oven at: 120°c, 150°c and 180°c. the effect of heating on performance of membranes w...

large unilamellar liposomes and multilamellar vesicles consisting of dmpc interacted with cationic phosphorus-containing dendrimers cpds g3 and g4. dsc and ζ -potential measurements have shown that liposomal-dendrimeric molecular recognition occurs due to the interaction between the complementary surface groups. calorimetric studies indicate that the enthalpy of the transition of the lipids tha...

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 ...
