The performance of anionic exchange resin Dowex 1x8 in the removal arsenic(V) from aqueous solutions was investigated. Batch experimentation carried out under different variables, including, stirring speed applied on system, pH solution, dosage and temperature. Due to characteristic speciation phases, this element solution is negligible at highly acidic or alkaline values, but it possible range...

Carcinoma of prostate (CaP) is the second most frequent malignant tumor occurring in men in Europe. Currently there is discussion on a wide range of potential CaP markers.One of them—nonprotein amino acid sarcosine, also known as N-methylglycine was chosen as a challenge for the development of microfluidic system with isolation by modified paramagnetic microparticles. Therefore, the aim of this...

Reduced, S-aminoethylated porcine ribonuclease was subjected to tryptic hydrolysis. A sequence of fractionation steps that included gel filtration and chromatography over SE-Sephadex C-50, Dowex 50-X2, and Dowex l-X2 afforded a series of glycopeptide fractions which were recognized to derive from three separate regions of the molecule. Heterogeneity of the attached polysaccharide chains preclud...

To make full use of computer vision technology in stores, it is required to consider the actual needs that fit characteristics retail scene. Pursuing this goal, we introduce United Retail Datasets (Unitail), a large-scale benchmark basic visual tasks on products challenges algorithms for detecting, reading, and matching. With 1.8M quadrilateral-shaped instances annotated, Unitail offers detecti...

The competition between magnetic order and Kondo effect is essential for the rich physics of heavy fermion systems. Nevertheless, how such manifested in quasiparticle bands a real periodic lattice remains elusive spectroscopic experiments. Here we report high-resolution photoemission study antiferromagnetic system CeCoGe3 with high TN1 21K. Our measurements reveal weakly dispersive 4f band at F...

Treatment of keratosulfates with alkali leads to the formation of 3,6-anhydroglucosaminyl groups in high yield. A similar reaction takes place with heparin and heparitin sulfate, though to a lesser extent. The anhydrosugar was isolated and compared with synthetic 3,6-anhydroglucosamine. The isolated compounds were identical in ion exchange chromatography in the amino acid analyzer and on Dowex ...

Fermentation of purines by Clostridium acidiuirici was observed in early studies (Barker and Beck, 1941) to yield acetate, carbon dioxide, ammonia, glycine and formate. The formation of glycine and formate was confirmed more recently by Radin and Barker (1953), and Bradshaw and Beck (1953). Sagers and Beck (1956) have demonstrated, as was first suggested by Radin and Barker (1953), that L-serin...
