“…As gemini surfactants have got an excellent antimicrobial activity, they are great corrosion inhibitors for carbon steel in acidic environments, due to the presence of nitrogen and oxygen atoms in their chemical structure [13]. In the work of Abdel Hameed et al [14], nonionic surfactants derived from plastic waste have been studied as corrosion inhibitors for mild steel in 2.0 M NaCl solutions. Weight loss, potentiodynamic polarization techniques and open circuit potential measurements have been used.…”

Benzyl dimethyl dodecyl ammonium chloride-zinc ion system, as quaternary ammonium salt (QA-Zn +2), was investigated as corrosion inhibitor for carbon steel in a 2.0 M sodium chloride solution, by different techniques such as weight loss, open circuit potential, potentiodynamic polarization and electrochemical impedance spectroscopic techniques. The inhibition efficiency of the used system (QA-Zn +2) increases with increasing mixed inhibitor concentrations and with rising temperatures. A synergistic effect exists between QA and Zn +2. Potentiodynamic polarization curves indicate that the used system mainly acts as an anodic mixed inhibitor. The polarization resistance values were (Rp) increased, and the interface capacitance (Cdl) was decreased in the mixed inhibitor system (QA-Zn +2) presence, more than in the case of individual inhibitors. The corrosion inhibition is due to the adsorption of (QA-Zn +2) onto the metal surface, and the formation of a barrier film that separates the metal from the corrosive medium. The maximum inhibition efficiency of 98% was obtained at 200 QA and 50 ppm Zn +2 of the mixed inhibitor system, due to a synergistic effect.

“…Nonionic polymeric surfactants derived from plastic waste considered as green corrosion inhibitors. These compounds were tested as an inhibitor for dissolution of steel in nitric acid, acetic acid and sodium chloride corrosive medium [17][18][19][20][21][22][23][24][25][26][27][28]. In the present study the P6000 was prepared, characterized and tested as an inhibitor for the dissolution of mild steel in 2.0 M H 2 SO 4 solution with open circuit potential, potentiodynamic polarization and weight loss methods and their results were compared.…”

Polyoxyethylene stearate of molecular weight 6000 (P6000) as nonionic polymeric surfactant was prepared by the esterification reaction between citric acid with polyethylene glycol (Mwt. 6000) in the presence of para toluene sulfuric acid, PTSA as a catalyst. The chemical structure of the prepared polymeric surfactant was recognized by FT-IR spectra. The inhibition of P6000 on mild steel surface in 2.0 M H 2 SO 4 solution was investigated using different techniques such as open circuit potential, potentiodynamic polarization and weight loss. The inhibition efficiency of the used polymeric surfactant increases with increasing its concentration, but decreases with rising temperature. The potentiodynamic polarization proved that P6000 acted as a mixed inhibitor controlling both cathodic and anodic reactions. The inhibition process is the result of the adsorption of P6000 on the mild steel surface through the formation of barrier film which separates the mild steel from the corrosive medium. The adsorption of P6000 on steel surface follows Langmuir's isotherm.

Background Dyslexia is characterized by difficulties in spelling and reading. The aim of this study is to identify domains of cognitive strength and weakness of students with dyslexia and to study the effect of an especially designed computerized training program on their reading abilities. This study was conducted on 2nd-grade primary school students in Asyut city, Egypt (n = 560). Identification of students with dyslexia was done using Arabic Reading Achievement test and a newly constructed computerized Arabic Cognitive Abilities diagnostic battery for Reading (CADB-R). Training was applied using a newly constructed Computerized Cognitive abilities training battery for reading (CATB-R). Results The prevalence of dyslexia was 13.9% (N = 52/373), and it was higher among girls (15.8%) than boys (11.7%). After application of the training program, there was a significant increase in post-training mean scores of CADB-R score in their total and all sub-items. Conclusions All struggling readers should be included in well-tailored research-based rehabilitation programs.
