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.

Oral Health Status, Salivary MMP-8& Secretory Leukocyte Peptidase Inhibitor (SLPI) Among Uncontrolled Type-I Diabetes Mellitus In Iraqi Patients
...Show More Authors

Background: diabetes is a metabolic disease characterized by hyperglycemia that results in deficiency or absence of insulin production. The dental caries and gingivitis/periodontitis are widespread chronic diseases in diabetes. The aim of the present study was determined the salivary matrix metalloproteinase (MMP-8), Secretory Leukocyte Peptidase Inhibitor (SLPI) and oral health status among uncontrolled diabetic group in comparison with healthy control group. Materials and Methods: The total sample composed of 90 adults aged (18-35) years. Divided into 60 uncontrolled diabetic patients (HbA1c >7%) and 30 healthy control group. Unstimulated saliva was collected from each subject with type-I DM, BMI, duration of diabetes, HbA1c%, DMFT, gingi

A Predictive Model for Estimating Unconfined Compressive Strength from Petrophysical Properties in the Buzurgan Oilfield, Khasib Formation, Using Log Data
...Show More Authors

Unconfined compressive strength (UCS) of rock is the most critical geomechanical property widely used as input parameters for designing fractures, analyzing wellbore stability, drilling programming and carrying out various petroleum engineering projects. The USC regulates rock deformation by measuring its strength and load-bearing capacity. The determination of UCS in the laboratory is a time-consuming and costly process. The current study aims to develop empirical equations to predict UCS using regression analysis by JMP software for the Khasib Formation in the Buzurgan oil fields, in southeastern Iraq using well-log data. The proposed equation accuracy was tested using the coefficient of determination (R²), the average absolute

            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

(التعليم في ايران في سنوات الثورة الدستورية 1905-1911م)

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
