Graphene oxide (GO) membranes on Nylon support were modified by UV-assisted reduction to control their behavior in the filtration of water containing organic pollutants. Pyridine, phenol, 2-naphthol and disperse blue 3 used as probe pollutants determinate molecular weight cut-off (MWCO) prepared. The prepared with GO loads 0.04 0.06 mg cm?2 subjected UV radiation from a Hg lamp (30 W m?2) for 3...

Two peptides with antioxidant activity were isolated from Pseudosciaena crocea proteins. Pseudosciaena crocea muscle was hydrolyzed with neutral protease to obtain Pseudosciaena crocea protein hydrolysates (PCPH). After ultrafiltration through molecular weight cut-off membranes of 10, 5 and 3 kDa and assessment of free radical scavenging ability, the fraction (PCPH-IV) with the highest antioxid...

In the construction process of a plastic concrete cut-off wall, concreting is usually performed using the termie pipe method. In this method, concreting is performed from the lowest point in the excavated trench (containing the slurry) using a funnel and the pipe connected to it. The concrete poured in the funnel gradually settles in the panel through the termie pipe which is beneath the slurry...

The colloidal organic matter (COM) was isolated from the exudates of three cultured phytoplonkters, namely chlophyte nanoflagellate Tetraselmis sp., diatom Chaetoceros socialis and dinoflagellate Prorocentrum minimum, Gulf Trieste (northern Adriatic Sea). isolation COM performed by ultrafiltration with molecular weight cut-off membranes 5 kDa final desalinisation dialysis. composition character...

background: brucellosis is a world-wide disease, which has a diverse clinical manifestation, and its diagnosis has to be proven by laboratory data. serum agglutination test (sat) is the most-widely used test for diagnosing brucellosis. the enzyme linked immunosorbent assay (elisa) can also determine specific antibody classes against brucella. it is a sensitive, simple and rapid test, which coul...

Defocusing effects in modulation transfer function (MTF) measurement of charge coupled device (CCD) cameras is the main focus of current paper. We introduce measuring Point-spread function (PSF) in order to calculate the MTF and further more we will study the shape of MTF and its cut-off frequency by adjusting the lens focusing in different locations. A collimated white light LED by broadband s...

Following on from recent studies which suggest in patients over 50 years of age an age-dependent D-dimer cut off of ‘age multiplied by 10’, in conjunction with a non-high clinical probability, can be used to safely exclude pulmonary embolism (PE), we read with interest the application of the same age-dependent D-dimer cut off to the exclusion of deep vein thrombosis (DVT) by Douma et al. Their ...

Forming hydrogels with precise geometries is challenging and mostly done using photopolymerization, which involves toxic chemicals, rinsing steps, solvents, bulky optical equipment. Here, we introduce a new method for in situ formation of well-defined geometry sealed microfluidic chip by interfacial polymerization. The the hydrogel programmed design capillary pinning structures bringing into co...
