In this work, Direct Contact Membrane Distillation (DCMD) was applied for the treatment of municipal wastewater collected from primary clarifier a plant (MWWTP). The water flux at 60℃ and 20℃ feed permeate side, respectively 51 kg/m2h in treating effluent. Meanwhile, electrical conductivity distillate good range 1.5 – 1.8 S/cm. Most representative parameters reuse (SS, nitrate, nitrite, phospha...

Protein crystallization techniques are very important in drug development. This paper discusses a membrane-based micro-volume dialysis method suitable for rapid and high-throughput protein crystallization. A droplet of solution was deposited on the membrane surface device. Crystallizing agents could be added to either directly or through membrane. The process easily monitored real time under mi...

Countercurrent membrane supported reactive extraction (MSRE) was studied for removal of carboxylic acids from aqueous streams with a PTFE capillary membrane. Analysis the mass transfer rates performed to support modeling process. Total coefficients ranging 2.0·10-7 4.0·10-7 m/s were obtained when extracting lactic acid 20 wt% tri-N-octyl amine in 1-decanol thicknesses 260 µm and 80 µm. The limi...

polyethylene glycol (peg) is a hydrophilic polymer, known to be capable to fuse numerous single cells in vitro, to join the membranes of adjacent neurons and giant invertebrate axons, and to seal damaged neural membranes. the molecular mechanism of the action of peg is still unknown. it is believed that peg dehydrates membranes and enables their structural components to resolve and rearrange in...

Outer membrane blebs are naturally shed by Gram-negative bacteria and are candidates of interest for vaccines development. Genetic modification of bacteria to induce hyperblebbing greatly increases the yield of blebs, called Generalized Modules for Membrane Antigens (GMMA). The composition of the GMMA from hyperblebbing mutants of Shigella flexneri 2a and Shigella sonnei were quantitatively ana...

Administration of S-adenosylmethionine (AdoMet), the main biological methyl donor, has been shown to exert favourable effects on liver disorders in man and animal models. The mechanism of action of AdoMet has, however, remained elusive, mainly owing to controversies with respect to its capacity to enter intact liver cells. Incubation of isolated rat hepatocytes with 2 or 50 microM -methyl-14C-A...
