Synthesis, Identification of Co(II), Cu(II) and Ni(II) Complexes with A Schiff Base–Azo Ligand Derived from Imidazol Derivatives, 4- Aminoacetophenon and 4- Chloroaniline and Study Their Physical Properties and Their Thermodynamic Stabilities

The complexes of Co(II), Cu(II) and Ni(II) were synthesized by using schiff base – azo as a ligand, which were prepared under this study by the reaction between the Schiff base diazonium salt and the imidazole derevitive. They were characterized by element analysis, FTIR spectroscopy and UV.VIS. spectroscopy. Their electric conductivity and magnetic features were determined. Their stepwise and overall stability constants and their thermodynamic data ( , and ) were determined. The results showed that all the complexes have paramagnetic features and all of them have good conductivity. The formula of the complexes under this paper were suggested by using the mole ratio method which lead to the formation of (1 : 2) metal : ligand formula for all the complexes. In all the complexes the coordinated sites was through N atoms of the azo groups and N atom of the imidazol ring. The suggested geometrical shapes of the complexes was the octahedral shape due to the ( d2sp3 ) hybridization. Their stepwise stability constants were determined, it was found that for all the complexes they were increased toward the addition of ligand that because of the chelate effect. Their overall stability constants were determined, it was found that for all the complexes were high that because of the chelate effect. Their thermodynamic functions ( , and ) were had negative value, that refer to good stability for the complexes and these results were satisfied with the spontaneous reaction and high stability complexes.

Parameter Estimation of Fractional Trigonometric Polynomial Regression Model

Trigonometric Polynomial Regression is a form of non-linear regression in which the relationship between the outcome variable and risk variable is Fractional modeled as 1/nth degree polynomial regression by combining the function of cos(nx) and sin(nx) on the value of natural numbers. The model was used to analyze the relationship between three continuous and periodic variables. Coefficients of the model were estimated using the Maximum Likelihood Estimate (MLE) method. From the results, the model obtained indicated that an increased in body mass index will increase the level of blood pressure while age may or may not have an influence on the blood pressure level. The values of the Coefficient of variation showed the variation in the dependent variable was well explained by the independent variables and the value of the adjusted coefficient of determination showed the model had a good fit with a high level of predictive power.

The spread of insufficiency of vitamin D may expose primary students at hazard for bone development, innate and adaptive immune responses, and increases risk of certain chronic diseases. The study provides an examination of the pervasiveness of 3 levels of sera 25(OH)D (≥30, 29-20, and <20 ng/ml) in students at the age 6 to 13 years. The data highlights that several of children in the Babylon city have levels of 25(OH)D some consider low and that urban girls have a lower record 25(OH)D. The serum is used to estimate the circulating level of vit.D by using microplate technique. Serum level 25(OH)D for children age 6 to 13 years is 28.77 ± 11.51ng/ml. Girls have suboptimal levels of 25(OH)D (25.96±9.95 ng/ml (95% CI:10.39-2.74) in comparison with the boys (32.53±12.44 [95% CI:5.75-2.29). The prevalence of levels at <10 ng/ml is 15%, less 20 ng/ml is 56%, and less 30 ng/ml is 29%. The predominance of sera '25(OH)D levels of <30 ng/ml is higher among boys (43%) in comparison with the girls (32%); urban (45%) in comparison with rural (30%). Based on a delegate test of Babylon kids of primary students, many children have inadequate levels of 25(OH)D.

Analytical Study of the Phenomenon of Money Laundering and its Impact on the Iraqi Banking Sector

This study discusses the phenomenon of money laundering and its impact on the financial sector in general and the Iraqi banking sector. The research methodology describes money laundering in detail and the three basic stages of money laundering, placement, layering, and integration. How and where money laundering is a key reason to address this problem and what is the role of governments? It also deals with the impact of money laundering on the Iraqi economy, which is the theft of banks, the suspension of industrial projects, terrorism and corruption. The most important recommendations that limit this phenomenon is international cooperation and legal assistance in money laundering investigations. The use of programming and electronic systems to enter the information of owners of real estate and businesses to detect suspicious activities. To reduce this problem requires the establishment of specialized units in the Central Bank and the Ministry of Finance, Justice and the security services to apply all laws against money laundering. As for the Iraqi banking sector, it is necessary to verify the identity of the owners of the funds deposited in banks. Inform the competent authorities by the bank's management of any suspicious activity. In addition to confirming the documents proving the legality of the funds deposited.
