Background: Conventional chemical coagulation is considered as the old method to color and COD removal in textile effluent. Electrocoagulation (EC) process is a robust method to achieve maximum removal. Methods: This work was designed to compare the result of operational parameters including optimum pH and coagulant concentration for chemical coagulation with ferric chloride and alum. Also, th...

This research investigates the potential use of pyrite cinder (PC) as an efficient Fenton-like catalyst for removal reactive azo dye Reactive Red 120 (RR120) from aqueous solutions. The characterization its PC structure and composition confirmed great to act catalytic iron source in a heterogeneous Fenton system. Dye optimization was performed terms dosage (0.4–8 g/L), H2O2 concentration (2–25 ...

Aerobic metabolism in biological systems produces reactive oxygen species, and defense against such prooxidants requires antioxidant activity, e.g., predominantly vitamins C and E in serum. Recently, flavonoids (polyphenols occurring widely in plants) have been investigated in vitro for their antioxidant activity; whether they are absorbed after ingestion is not clear. Using a chemiluminescent ...

Peroxynitrite, the reactive species formed in vivo by the reaction of nitric oxide with superoxide anion, is capable of diffusing across erythrocyte membranes via anion channels and passive diffusion (A. Denicola, J. M. Souza, and R. Radi, Proc. Natl. Acad. Sci. USA 95, 3566-3571, 1998). However, peroxynitrite diffusion could be limited by extracellular targets, with the reaction with CO(2) (k(...

Synthetic dyes, azo dye in particular, are widely found in the effluents from textile industries. The persistence and toxicity of these compounds cause adverse impact in the receiving streams. A mixture of isolated cultures, from domestic sewage treatment plant was found to decolourize reactive azo dyes, Red RB, Blue M2B and Yellow, efficiently in the absence of added external nitrogen source. ...

Abstract Generally, red wines made from cold-hardy hybrid grapes have much lower tannin content than Vitis vinifera and they are often perceived as being of quality. This study evaluated the chemistry sensory perception whole-cluster (WC) fermented “Frontenac” “Marquette” Iowa (F-ISU, M-ISU) Minnesota (M-UMN). Three conditions were compared: Control 0% WC (w/w), 25% 50% (w/w). The had significa...

OBJECTIVE The aim of this study was to evaluate the protective effects of quercetin, rutin, hesperidin and myricetin against reactive oxygen species production with the oxidizing action of tert-butylhydroperoxide in erythrocytes from normal subjects and sickle cell anemia carriers treated with hydroxyurea. METHODS Detection of intracellular reactive oxygen species was carried out using a lipo...

We present Big Red, a visual editor for bigraphs and bigraphical reactive systems, based upon Eclipse. The editor integrates with several existing bigraph tools to permit simulation and reachability analysis of bigraphical models. We give a brief introduction to the bigraphs formalism, and show how these concepts manifest within the tool using a small motivating example developed in Big Red. We...
