Treatment isolated fungi from laboratory tools in some Baghdad hospitals by using biosynthesized nanoparticles
...Show More Authors

The study aims to biosynthesized of sliver nanoparticle from aqueous extract of olive leave and evaluate the effectiveness of the synthesis AgNPs against isolated fungi. The study mediating fifty samples were taken from various tools in laboratory from five hospitals in Baghdad. Four species of fungi were identified depending on the morphological and microscopic characteristics. The most common isolated fungi based on their frequency ratio were as follows Aspergillus niger 87.5%, Aspergillus flavus 62.5%, Aspergillus fumigatus 53.5% and Aspergillus nidulans 37.7%.The Biosynthesis of silver nanoparticle developed a rapid, eco-friendly and convenient green method for the stable silver nanoparticles (AgNPs) were synthesised with an average diameter of 30 ± 60 nm and like spherical in shape, using the aqueous solution of the Olive tree (Olea europaea) leaves extract.The reaction is carried out at 10-3M of silver nitrate. The AgNPs synthesized were confirmed by their change of color to (dark brown-grey). The characterization was studied using UV-Visible spectroscopy, Scanning Electron Microscopy (SEM) and Atomic Force Microscopy (AFM). Inhibition effect of AgNPs against fungi has been studied using well diffusion method by studying  the effect of different concentration (100, 75, 50 and 25). The results revealed that the AgNPs have considerable antifungal activity comparison with alcohol. The obtained results indicate that the highest level of inhibition zone was detected at the concentration of 100 µg/ml of AgNPs, where the inhibition zones are (23.33 ± 4.41) for A. flavus and the lowest level of  inhibition zone was detected at  the concentration 25 µg/ml of AgNPs ,where the inhibition zones are (6.00 ± 1.15) for A.nidalus. While using alcohol the highest level of inhibition zone was detected at the concentration of 100 µg/ml of Alcohol, where the inhibition zones are (12.33 ± 1.45) for A.nidalus, and the lowest level of  inhibition zone was detected at  the concentration 25 µg/ml of Alcohol ,where the inhibition zones are (4.67± 0.33) for A.flavus.

Estimate the Rate of Contamination in Baghdad Soils By Using Numerical Method
...Show More Authors

The aim of this paper is to evaluate the rate of contamination in soils by using accurate numerical method as a suitable tool to evaluate the concentration of heavy metals in soil. In particular, 2D –interpolation methods are applied in the models of the spread the metals in different direction.The paper illustrates the importance of the numerical method in different applications, especially nvironment contamination. Basically, there are many roles for approximating functions. Thus, the approximating of function namely the analytical expression may be expressed; the most common type being is polynomials, which are the easy implemented and simplest methods of approximation. In this paper the divided difference formula is used and extended

Treatment Missing Data of Daily and Monthly Air Temperature in Iraq by Using Mean Method
...Show More Authors

Frequent data in weather records is essential for forecasting, numerical model development, and research, but data recording interruptions may occur for various reasons. So, this study aims to find a way to treat these missing data and know their accuracy by comparing them with the original data values. The mean method was used to treat daily and monthly missing temperature data. The results show that treating the monthly temperature data for the stations (Baghdad, Hilla, Basra, Nasiriya, and Samawa) in Iraq for all periods (1980-2020), the percentage for matching between the original and the treating values did not exceed (80%). So, the period was divided into four periods.  It was noted that most of the congruence values increased, re

Biodisintegration of human mucin protein by protease produced from Escherichia coli AJ55 isolated from Urinary Tract Infection of Iraqi pa-tients
...Show More Authors

      Proteases have various applications in the food, pharmaceutical, medicine, pathogenicity of some pathogenic bacteria, and detergent sectors as well as meeting the needs of approximately 60% of the global enzyme industry, whereas they catalyze the breakdown of protein molecules into peptides and amino acids. Production and purification of protease enzyme by the isolate Escherichia coli AJ55 was scrutinized in the present study. Cultivation optimum conditions, were various complex medium, carbon source, nitrogen source, temperature, pH of the medium, and time of incubation were optimized to enhance the total protease production in shake flask culture of E.coli AJ55.

Estimation of Mechanical Rock Properties from Laboratory and Wireline Measurements for Sandstone Reservoirs
...Show More Authors

Mechanical rock properties are essential to minimize many well problems during drilling and production operations. While these properties are crucial in designing optimum mud weights during drilling operations, they are also necessary to reduce the sanding risk during production operations. This study has been conducted on the Zubair sandstone reservoir, located in the south of Iraq. The primary purpose of this study is to develop a set of empirical correlations that can be used to estimate the mechanical rock properties of sandstone reservoirs. The correlations are established using laboratory (static) measurements and well logging (dynamic) data. The results support the evidence that porosity and sonic travel time are consistent i
