Study of the Structural, Optical, and Morphological Properties of SnO2 Nanofilms under the Influence of Gamma Rays
...Show More Authors

This study reports the fabrication of tin oxide (SnO2) thin films using pulsed laser deposition (PLD). The effect of 60Co (300, 900, and 1200 Gy) gamma radiation on the structural, morphological, and optical features is systematically demonstrated using X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), atomic force microscopy (AFM), and ultraviolet-visible light analysis (UV-Vis), respectively In XRD tests, the size of the crystallites decreased from 45.5 to 40.8 nm for the control samples and from 1200 Gy to 60Co for the irradiated samples. Using FESEM analysis, the particle diameter revealed a similar trend to that attained using XRD; in particular, the average diameters were 93.8 and 79.9 nm for the samples mentioned above. A similar profile was observed for the AFM analysis in which an increase in the radiation dose from 300 to 1200 Gy resulted in a decrease in the RMS values from 74.6 to 32.25 nm. Contrariwise, the calculated optical band gap demonstrated an increasing profile where optical band gaps of 3.08 and 3.18 eV were acquired for control and samples irradiated with 900 Gy. However, the attained optical band gap was further increased to 3.24 eV due to the 60Co gamma radiation increment to 1200 Gy.

Effect of Additives on Rheological Properties of Invert Emulsions
...Show More Authors

This research deals with study of the effect of additives on rheological properties (yield point, plastic viscosity ,and apparent viscosity) of emulsions. Twenty seven emulsion samples were prepared; all emulsions in this investigation are invert emulsions when water droplets are dispersed in diesel oil. The resulting emulsions are called water-in-oil (W/O) emulsions. The rheological properties of these emulsions were investigated using a couett coaxial cylinder rotational viscometer (Fann-VG model 35 A), by measuring shear stress versus shear rate. It was found that the effect of additives on rheological properties of emulsions as follow: the increase in the concentration of asphaltic material tends to increase the rheological propertie

Effect of Biopolymer Alginate on some properties of concrete
...Show More Authors

Alginate from Large brown seaweeds act as natural polymer has been investigated as polymer and has been added to concrete in different percentages ( 0% , 0.5% , 1% and 1.5% ) by the cement weight and the study show the effect of using alginate biopolymer admixtures on  some of the fresh properties of the concrete (slump &  the density  fresh) also in the hardened state (  Compressive strength , Splitting tensile strength  and Flexural strength ) at 28 days. The mix proportion was (1:2.26:2.26) (cement: sand: gravel) respectively and at constant w/c equal to 0.47. The results indicate that the use of alginate as a percent of the cement weight possess a positive effect on fresh properties of co

Job Enrichment and Its Influence in Organizational Cynicism among Workers in Iraqi Youth and Sport Forums
...Show More Authors

This study aims to (1) identify the level of job enrichment and organizational cynicism among workers in some youth and sport forums, and (2) identify the influence the job enrichment in the organizational cynicism from their perspective. A descriptive survey was used to guide this study. The study included 478 workers who were randomly selected from the youth and sport forums in Baghdad City in 2019. The Job Enrichment Scale and the Organizational Cynicism Scale were used. Data were analyzed using the statistical package for social science, version 26. The study results revealed that the level of job enrichment and organizational cynicism among workers were unsatisfactory. This calls for paying more attention to these phenomena and improve
