A theoretical and protection study was conducted of the corrosion behavior of carbon steel surface with different concentrations of the derivative (Quinolin-2-one), namly (1-Amino-4,7-dimethyl-6-nitro-1H-quinolin-2-one (ADNQ2O)). Theoretically, Density Functional Theory (DFT) of B3LYP/ 6-311++G (2d, 2p) level was used to calculate the optimized geometry, physical properties and chemical inhibition parameters, with the local reactivity to predict both the reactive centers and to locate the possible sites of nucleophilic and electrophilic attacks, in vacuum, and in two solvents (DMSO and H2O), all at the equilibrium geometry. Experimentally, the inhibition efficiencies (%IE) in the saline solution (of 3.5%) NaCl were studied using potentiometric polarization measurements. The results revealed that the (%IE) for carbon steel corrosion by ADNQ2O is (89.88%). The obtained thermodynamic parameters support the physical adsorption mechanism. The adsorption followed the Langmuir isotherm. The surface change on carbon steel was studied using SEM (Scanning Electron Microscopy).
It is weII known that Iraq was alerted to the fact the need to catch up with globalization and the need to attract foreign investment , perhaps the solutions is able to or control over its economic problems which centers on the problem pf unemployment .
Imposing the Investment Law No (13) for the year 2006 is the most basic steps to attract foreign investment through Madmen Law of incentives KaIiafaouat tax , it must be the study of those exemptions and compare them with tax exemptions for some of the investment Laws of the Arab countries as one investment Lebanese , Jordanian and Egyptian that we have the knowledge Marvel Law Iraqi investment in respect of such &

The Constitutional Revolution is an important event in the modern history of Iran. It led to major changes in the political system and the education system. In addition to it, laws were enacted that contributed to increasing the number of students who were unable to learn because of their deteriorating economic situation. The revolution also contributed to opening the way for girls to enter the country. Schools after that was forbidden due to the opposition of the clergy, as the enemy of female education is contrary to Sharia, and different classes appeared in society calling for the fight against ignorance, the development of learning, the education of girls, and the establishment of modern schools for their education
Knowledge was varied at all level, and it reached to all sector of society during the Arabic Islamic Renaissance that lasted five centuries. Its creativity and originality had a great effect on every aspect of life in the countries laborited by Arab Muslims.Esfahan was one of these countries, in which Arab Muslims played a great role in dissemination of knowledge and science in the society.
The role of Arab bookworms and thinkers in circularizing Islamic knowledge was distinguished. Islamic religion improved the behavior of Arabic people so they became able to learn people and nations the principles of knowledge. This lead to develop the scientific movement by man

Religious is the faith of finding powers with senses , it aims to connect between groups of behaviors and spirit guides that presents interpretation to person about myths of death and life .
It is difficult to understand ancient Iraqi civilization before we can study religious and faiths . This civilization is an everlasting until today in spite of passing more than 5000 years to emergence it in Sumerian .It is concluded that character of Mesopotamia has deep hidden faith who made Gods for them these which characterized with four characters that are similarity ,similarity &
