Microlens array homogenizers are an attractive choice in the field of radiometry and photometry to generate highly uniform beams with high efficiency. In the present paper a microlens array homogenizer used to determine the spectral responsivity of large size, partially filtered photometer is presented. The effect of nonuniformity of the field is shown to be smaller than 0.2% in the whole visib...

conclusions anova results showed that the effect of cycle and time on the selected bacterial removal efficiency were more important than that of the microbial concentration. results the results showed that e. coli and e. faecalis were effectively treated at 10 pulse/s in 9 minutes and 6 log cfu/ml bacterial suspension (p < 0.0001 for e. coli with 99.99% (4 log) and p = 0.0002 for e. faecalis wi...

Current work aims to study the mechanical and dynamical properties of non-woven bamboo (B)/woven kenaf (K)/epoxy (E) hybrid composites filled with nanoclay. The nanoclay-filled BK/E were prepared by dispersing 1 wt.% nanoclay (organically-modified montmorillonite (MMT; OMMT), (MMT), halloysite nanotube (HNT)) high shear speed homogenizer followed hand lay-up fabrication technique. effect adding...

Abstract In this work, the efficiency of a polyelectrolyte complex (PEC) to retain different cellulose micro/nanofibers (CMNFs) during paper formation and improve physical properties recycled unbleached fiber was analyzed. CMNFs were obtained from commercial bleached eucalyptus pulp (BEP) using PFI refiner followed by chemical treatment with oxalic acid at two concentrations. Finally, fibrillat...
