The inhibitive action of Reactive Red (RR31) dye against corrosion of carbon steel in 1M acetic acid solution has been studied using gravimetric method at temperature ranged (288-318)K. The antibacterial activity for the different concentrations of RR31 dye against different bacterial species was studied. The experimental data indicates that this dye acts as a potential inhibitor for carbon-steel in acetic acid medium and the protection efficiency increase with increasing (RR31) dye. The adsorption of (RR31) dye on the carbon steel surface was found to follow Langmuir adsorption isotherm. Thermodynamic data for the adsorption process such as Gibbs free energy change ∆Gads, enthalpy change ∆Hads, and entropy change ∆Sads were estimated. The results showed that the different concentrations of RR31 dye has antibacterial ability.
The city of Nishapur is one of the cities that had a prominent position and a clear impact on the flourishing of the scientific movement, and this position that it enjoyed was achieved because of the scholars who were incubating them. Who had a great role in the flourishing of scientific life through his scientific activity, as he worked as a teacher for thirty years in its regular school, in addition to his work in rhetoric, preaching and scientific circles, in addition to his many books in various sciences, as he did not specialize in one science only, but rather collected all the sciences of his time and excelled in them. He enriched the Arab and Islamic library with it.

Equation of motion of the plates was derived using the principle of virtual work and solved using modified Fourier displacement function that satisfies general edge conditions. The eigenvalue problem generated by using Ritz method, the set of linear algebraic equations can be solved using MATLAB for symmetric and anti-symmetric, cross and angle-ply laminated plate considering some design parameters such as aspect ratios, number of layers, lamination type and orthotropic ratio.
