In recent years, optical fiber Raman amplifiers (FRA) have been widely investigated. FRAs use the transmission fiber itself as the gain medium, creating a lossless communication link and reducing the overall noise figure. The later and other promising characteristics put them among the most important technologies in lightwave systems. In Raman amplified(More)
This work aimed to study the pH and the transmembrane pressure effects during the recovery of α and β amylases enzymes from corn malt (Zea mays) by hollow fiber membrane. The optimal condition was obtained for a statistical model, established by response surface methodology (RSM). The response surface analysis showed that the best operation condition for(More)
