Theoretical and Experimental Study of Corrosion Behavior of Carbon Steel Surface in 3.5% NaCl and 0.5 M HCl with Different Concentrations of Quinolin-2-One Derivative
...Show More Authors

A theoretical and protection study was conducted of the corrosion behavior of carbon steel surface with different concentrations of the derivative (Quinolin-2-one), namely 7-Ethyl-4-methyl-1-[(4-nitro-benzylidene)-amino]-1H-quinolin-2-one (EMNQ2O). Theoretically, Density Functional Theory (DFT) of B3LYP/ 6-311++G/ 2d, 2p level was carried out to calculate the geometrical structure, physical properties and chemical inhibition chemical parameters, with the local reactivity in order to predict both the reactive centers and to know the possible sites of nucleophilic and electrophilic attacks, in vacuum and two solvents (DMSO and H2O), all at the equilibrium geometry. Experimentally, the inhibition efficiencies (%IE) in (3.5% NaCl) and (0.5M HCl) solutions were studied using potentiometric polarization measurements. The results revealed that the (%IE) in the salty solution (94.98%) is greater than that in the acidic solution (81.40%). The thermodynamic parameters obtained, supported the physical adsorption mechanism and the adsorption followed the Langmuir adsorption isotherm. The surface changes of the carbon steel were studied using SEM (Scanning Electron Microscopy) and AFM (Atomic Force Microscopy) techniques.

The book of Alphendidad is considered as an important part of the holy book of
Avesta in the Zoroastrian religion. It is a religious and urbanization book that consists of a
number of chapters dealing with the creation. The book includes 22 chapters, mostly edited
as a dialogue between Ahuaramzda the god of goodness and his prophet Zoroaster. The
biggest chapter deals with the rules of purification of vices of the devil and dismissing it of
the places around, hence it is the book of law of Zoroastrian about the important animals,
birds , insects, and reptiles and their categorization according to their creation; creatures of
the spirit of goodness and creatures of the spirit of evilness.
Some of these creatures ar

Federal Russia remains the central player in the space of post-Soviet Union,
particularly in the regions of Middle Asia and the Caucasus , which set standard for
the local transformations of the two regions.
The Russian concern continued about the shift of power in the
world, as long as Russia is concerned with limiting the action of the United States
in the area in which Russia sees as vital area to its national interests. Russia's
nationalists play a main role in reviving Russia's influence in Middle Asia as a vital
area and the natural ally of Russia, but without resorting to the old ways of using
the threat of military force.
The idea of the return of Russia as a superpower in the global arena in

objective of this research is to identify some of the obstacles that face secondary school teachers of the Arabic language courses in using modern teaching methods in class.

The research focuses on secondary school teachers of the Arabic language courses at the central region of Nineveh Governorate for the school year (2008-2009). 30 teachers out of 792, were randomly chosen to apply the research tool upon.

To fulfill the objective of this research, the researcher first surveyed a number of teachers , he then identified four categories of obstacles; obstacles related to school administrative system and environment, the teacher, courses and pupils, and the nature of teaching method
