Assessment of Heavy Metal Contamination in Euphrates River Sediments from Al-Hindiya Barrage to Al-Nasiria City, South Iraq
...Show More Authors

The degree of contamination in the sediments of the Euphrates River (Shatt Al-
Hindiya), for the metals As, Cd, Co, Cu, Cr, Mn, Ni, Pb, Sc Se, Sr, V and Zn has
been evaluated using the index of geo-accumulation (I-geo), Enrichment factor (EF),
Contamination factor (CF) and pollution load index (PLI), whereat the I-geo has
been widely utilized as a measure of pollution in freshwater sediment. Enrichment
factor (EF) is one widely used as approach to characterize the degree of
anthropogenic pollution to establish enrichment ratios, while the pollution load
index (PLI) represents the number of times by which the heavy metal concentrations
in the sediment exceeds the background concentration, and gives a summative
indication of the overall level of heavy metal toxicity in a particular sample. By
using these numerical sediments indexes we found that the Sediments of Euphrates
River in the study area are polluted by the metals of Nickel (maximum 194ppm) and
Strontium (maximum 543ppm), and moderately polluted by the metals of Copper
(maximum 47.9), Cobalt (maximum 22.8ppm), Chromium (maximum 111ppm) and
Selenium (maximum 1.1ppm), while the sediments of Euphrates River are not
polluted by the metals of Arsenic (maximum 10.2ppm), Cadmium (maximum
0.29ppm), Manganese (maximum 949ppm), Lead (maximum 14.8ppm), Scandium
(maximum 8.96ppm), Vanadium (maximum 81ppm) and Zinc (maximum 91ppm).

Microwave Assisted Synthesis, Solution State, Spectral Studies and Theoretical Treatment of Pd(II) , Pt(IV) and Au(III) ions Complexes Containing 2-Benzamide Benzothiazole
...Show More Authors

2-benzamide benzothiazole complexes of Pd(II) , Pt(IV) and Au(III) ions were prepared by microwave assisted radiation. The ligand and the complexes were isolated and characterized in solid state by using FT-IR, UV-Vis spectroscopy, flame atomic absorption, elemental analysis CHNS , magnetic susceptibility measurements , melting points and conductivity measurements. The nature of complexes in liquid state was studied by following the molar ratio method which gave results approximately identical to those obtained from isolated solid state; also, stability constant of the prepared complexes were studied and found that they were stable in molar ratio 1:1.The complexes have a sequar planner geometry except Pt(IV) complex has octahedral .

 A study was conductedto determine thethe effects of two insect pathogenic fungiMetarhizium anisopliae and Beauvaria bassiana In biological control and comparing, insecticide, Icon, on larva , pupa and adults stage of house fly  was tested. The results  revealed non-significantly superiority differences in the percentages of cumulative death between the recommended concentration of Icon and the M.anisopliae(2 × 1011), but the results showed, significant difference in accumulation death between M. anisoplia ( 2 × 1011 ) and  B. bassiana were found at the same concentration, the accumulation death of  M.anisoplia reached to 100, 80, 95% for larval, pupa and stage after 96  hours respectively,  com

A Semi-Empirical Equation based on the Strut-and-Tie Model for the Shear Strength Prediction of Deep Beams with Multiple Large Web Openings
...Show More Authors

The behavior and shear strength of full-scale (T-section) reinforced concrete deep beams, designed according to the strut-and-tie approach of ACI Code-19 specifications, with various large web openings were investigated in this paper. A total of 7 deep beam specimens with identical shear span-to-depth ratios have been tested under mid-span concentrated load applied monotonically until beam failure. The main variables studied were the effects of width and depth of the web openings on deep beam performance. Experimental data results were calibrated with the strut-and-tie approach, adopted by ACI 318-19 code for the design of deep beams. The provided strut-and-tie design model in ACI 318-19 code provision was assessed and found to be u

Electro-polymerization of poly eugenol on ti and ti alloy dental implant treatment by micro arc oxidation using as anti-corrosion and anti-microbial
...Show More Authors

In this work, electrochemical process was presented to polymerized eugenol on Gr.2 and Gr.5 titanium alloys before and after treated by Micro Arc Oxidation (MAO), where Gr.2 is commercial pure titanium and Gr.5 is Ti-6Al-4V dental alloys. The deposited layers were characterized by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR). The adhesion strength of polymeric thin-film was estimation by using pull-off adhesion test and the result was the adhesion strength of PE was (1.23 MPa) on Gr.2 before MAO and increase to (1.98 MPa) on Gr.2 after MAO treatment. The corrosion behavior of Gr.2 and Gr.5 alloy in artificial saliva environment at
