The inhibition action of Aloe Vera leaf extract as environmentally friendly inhibitor for the corrosionprotection of stainless steel in 1 M H2SO4 solution was studied by electrochemical techniques as well asscanning electron microscope. The results of linear polarization and electrochemical impedancespectroscopy proved the effectiveness of Aloe Vera extract as concentration increased. Corrosioninhibition of Aloe extract was also studied by electrochemical noise (EN). Employing EN, differentaspects like transient analysis, noise resistant and characteristic charge were characterized. Moreover, aliterature review of Aloe Vera characterization using high-performance liquid chromatography and GCMSwas carried out.

In this paper, He’s energy balance method is applied to nonlinear vibrations and oscillations. The method is applied to four nonlinear differential equations. It has indicated that by utilizing He’s energy balance method (HEBM), just one iteration leads us to high accuracy of solutions. It has illustrated that the energy balance methodology is very effective and convenient and does not require linearization or small perturbation. Contrary to the conventional methods, in energy balance method, only one iteration leads to high accuracy of the solutions. The results reveal that the energy balance method is very effective and simple. It is predicted that the energy balance method can be found wide application in engineering problems, as indicated in following examples.
