Última Aniline effect on concrete steel rebar degradation in saline and sulfate media CIGR Journal Olugbenga Adeshola Omotosho; Covenant University; Cleophas Akintoye Loto; Covenant University, Ota; Oluseyi Olanrewaju Ajayi; Covenant University, Ota; Joshua Olusegun Okeniyi; Covenant University, Ota. Electrochemical potential monitoring experiments were performed on mild steel rebars embedded in concrete admixed with aniline inhibitor and fixed amount of sodium chloride salt partially immersed in sulfuric acid and sodium chloride solution.  The open circuit potential corrosion monitoring technique was employed and the potential readings were taken in accordance with ASTM C 876.  Repressive attribute and consistency of the inhibitor was then estimated by the Weibull probability density distribution as an extreme value statistical modeling approach to study performance effectiveness and to predict the most efficient inhibitor concentration in each media.  Aniline effect on the compressive strengths of the reinforced concrete samples was also investigated...

Ano: 2011 URL: http://www.cigrjournal.org/index.php/Ejounral/article/view/1830 Linear competitive inhibition of human tissue kallikrein by 4-aminobenzamidine and benzamidine and linear mixed inhibition by 4-nitroaniline and aniline BJMBR Sousa,M.O.; Miranda,T.L.S.; Costa,E.B.; Bittar,E.R.; Santoro,M.M.; Figueiredo,A.F.S.. Hydrolysis of D-valyl-L-leucyl-L-arginine p-nitroanilide (7.5-90.0 µM) by human tissue kallikrein (hK1) (4.58-5.27 nM) at pH 9.0 and 37ºC was studied in the absence and in the presence of increasing concentrations of 4-aminobenzamidine (96-576 µM), benzamidine (1.27-7.62 mM), 4-nitroaniline (16.5-66 µM) and aniline (20-50 mM). The kinetic parameters determined in the absence of inhibitors were: Km = 12.0 ± 0.8 µM and k cat = 48.4 ± 1.0 min-1. The data indicate that the inhibition of hK1 by 4-aminobenzamidine and benzamidine is linear competitive, while the inhibition by 4-nitroaniline and aniline is linear mixed, with the inhibitor being able to bind both to the free enzyme with a dissociation constant Ki yielding an EI complex, and to the ES complex with...
