A new two Schiff bases derivatives was synthesized and characterized with studying their biological activity and employed Manganese(II), Cobalt(II), Nickel(II), Copper(II) and Mercury(II) complexes: 2-((Z)-4-((Z)-2-hydroxy-1,2- diphenylethylideneamino)-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-ylideneamino) benzoic acid and (E)-4-(2-hydroxy-1,2- diphenylethylideneamino)-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one. The first ligand were obtained through are action of Benzoin and 4-Aminoantipyrine while the second result from the condensation of the first ligand with 2-aminobenzoic acid. Ten new coordination compounds were synthesized and structurally characterized: [Co(L1)(Cl)], [Cu(L1)(Cl)] [Ni(L1)(Cl)], [Mn(L1)(Cl)], [Hg(L1)(Cl)], [Co(L2)], [Ni(L2)], [Cu(L2)], [Mn(L2)] and [Hg (L2)]. All of the suggested chemical structures of the prepared ligands and metal complexes are confirmed by using FT-IR, UV, 1H & 13C-NMR spectra. Most of the prepared compounds show antibacterial activity to Staphylococcus aureus, Escherichia coli, Bacillussubtilis and Pseudomonasaeroginosa.
Synthesis of a new class of Schiff-base ligand with a tetrazole moiety to form polymeric metal complexes with CoII, NiII, ZnII, and CdII ions has been demonstrated. The ligand was synthesised by a multi-steps by treating 5-amino-2-chlorobenzonitrile and cyclohexane -1,3-dione, the 5,5'-(((1E,3E)-cyclohexane-1,3-diylidene)bis(azanylylidene))bis(2-chlorobenzonitrile) was obtained. The precursor (M) was prepared from the reaction 5,5'-(((1E,3E)-cyclohexane-1,3-diylidene)bis(azanylylidene))bis(2-chlorobenzonitrile) with NaN3 to obtained (1E,3E)-N1,N3-bis(4-chloro-3-(1H-tetrazol-5-yl)phenyl)cyclohexane-1,3-diimine (N). By reacting the precursor (M) with CS2

The batch experiments were carried out to determine the adsorption isotherm constants for each adsorbent, and five isotherm models were tested to choose the best fit model for the experimental data. The pore, surface diffusion coefficients and mass transfer coefficient were found by fitting the experimental data to a theoretical model. Partial differential equations were used to describe the adsorption in the bulk and solid phases. These equations were simplified and the

The risk of complications increases with age if the disease is not managed properly. Diabetic neuropathy is caused by excessive blood glucose and lipid levels, resulting in nerve damage. Apelin is a peptide hormone that is found in different human organs, including the central nervous system and adipose tissue. The aim of this study is to estimate Apelin levels in diabetes type 2 and Diabetic peripheral Neuropathy (DPN) Iraqi patients and show the extent of peripheral nerve damage. The current study included 120 participants: 40 patients with Diabetes Mellitus, 40 patients with Diabetic peripheral Neuropathy, and 40 healthy

The current research aims to measure the job satisfaction of educational counselors in the general directorate of education of the second Rusafa in the ministry of education of Iraq. Moreover, it aims to identify the significant differences in job satisfaction according to the gender (Male-Female), the length of service (less than 15 years more than 15 years), and the relationship between these two variables. To achieve the objectives of the research, the researcher developed a scale to measure job satisfaction. This tool was applied to sample of (100) educational counselors selected randomly. The results showed that educational counselors have job satisfaction, in which males are more satisfied in their job than females. The results als
