Investigating the Antioxidant and Apoptosis Inducing Effects of Biologically Synthesized Silver Nanoparticles Against Lymphoma Cells in Vitro
...Show More Authors

     The current study aimed to synthesize silver nanoparticles (Ag NPs) in a safe and eco-friendly biological method using green tea extract, characterize them using UV-vis spectroscopy, FTIR, XRD, FESEM, and AFM tools, then investigate their antioxidant potentials against DPPH and their cytotoxicity toward lymphoma cells using MTT and ethidium bromide/propidium iodide dual staining assays, and their genotoxic capacities by assessing their effects on the gene expression of p53, caspase3, bcl-2, and bax genes by qPCR and DNA fragmentation.  Results confirmed the synthesis of silver nanoparticles; the UV-vis results showed a peak of absorbance at 414 nm; FTIR analysis showed absorbance belonging to the functional groups of green tea; XRD assay results confirmed the crystallinity of Ag NPs; and AFM revealed a mean diameter of around 24.37 nm. Finally, FESEM showed that the shape of Ag NPs was that of spherical aggregated nanoparticles. The synthesized nanoparticles showed antioxidant activity and cytotoxic effects against lymphoma cells, with an IC50 =  1.138 μg/ml. Cell staining results showed alternations in the shape of treated cells due to apoptosis. Ag NPs affected gene expression as they increased proapoptotic genes p53, caspase3, and bax by 3.3, 2, and 4.25fold, respectively, while decreasing antiapoptotic gene expression bcl-2 by 0.59fold. We concluded that the biological way is an efficient way to synthesize silver nanoparticles, and the synthesized NPs have antioxidant potential and are cytotoxic and genotoxic toward lymphoma cells; thus, they may be utilized in related biomedical applications.

Evaluating the Performance of High Modulus Asphalt Concrete Mixture for Base Course in Iraq
...Show More Authors

In the 1980s, the French Administration Roads LCPC developed high modulus mixtures (EME) by using hard binder. This type of mixture presented good resistance to moisture damage and improved . mechanical properties for asphalt mixtures including high modulus, good fatigue behaviour and excellent resistance to rutting. In Iraq, this type of mixture has not been used yet. The main objective of this research is to evaluate the performance of high modulus mixtures and comparing them with the conventional mixture, to achieve this objective, asphalt concrete mixes were prepared and then tested to evaluate their engineering properties which include moisture damage, resilient modulus, permanent deformation and fatigue characteristics. These prope

Elastic electron scattering from Te-isotopes in the framework of Skyrme-Hartree-Fock method
...Show More Authors

The ground state charge, proton and matter densities and their rms radii of some Te-isotopes are studied by means of the Skyrme–Hartree–Fock (SHF) method with the Skyrme parameters namely; SKB, SGI, SKM, SKX, MSK7 and SLy4. Also, the neutron skin thickness, the elastic charge form factor and the binding energy per nucleon are calculated in the same framework. The calculated results have been compared with the available experimental data.

Estimation of the Rock Mechanical Properties Using Conventional Log Data in North Rumaila Field
...Show More Authors

Hydrocarbon production might cause changes in dynamic reservoir properties. Thus the consideration of the mechanical stability of a formation under different conditions of drilling or production is a very important issue, and basic mechanical properties of the formation should be determined.
There is considerable evidence, gathered from laboratory measurements in the field of Rock Mechanics, showing a good correlation between intrinsic rock strength and the dynamic elastic constant determined from sonic-velocity and density measurements.
The values of the mechanical properties determined from log data, such as the dynamic elastic constants derived from the measurement of the elastic wave velocities in the material, should be more a

Determination of Polycyclic Aromatic Hydrocarbon (PAHs) in the Tigris River through Passing Baghdad Province
...Show More Authors

Tigris River receives many pollutants while passing through Baghdad province due to increasing of population, discharge of untreated industrials, agricultural wastes on the river. The present study was conducted from January 2013 to December 2013 on the Tigris River starting from Al-Muthana Bridge to Al-Zaufurania city before it's jointed with Diyalla Tributaries. Six stations were chosen on the Tigris River along Baghdad city. The study was included measuring the bimonthly concentrations and distributions of polycyclic aromatic hydrocarbons (PAHs) in the samples of surface water. The sixteen polycyclic aromatic hydrocarbons (PAHs) listed by USEPA as priority pollutants (Naphthalene, Acenaphthalene, Acenaphthene, Fluorene, Phenanthrene,

A Critical Discourse Analysis of Women’s Representation in Maysaloon Hadi’s Novel The Black Eyes
...Show More Authors

This study applies a discourse analysis framework to explore the portrayal of women in Maysloon Hadi’s novel (The Black Eyes) (2011), using Critical Discourse Analysis (CDA) and Norman Fairclough’s tri-dimensional model (1989) as the analytical foundation. It investigates the roles and challenges women face in the novel. While there is growing interest in the portrayal of women in literature, Iraqi literature—especially from the perspective of Iraqi women writers remains underexplored. Hadi’s *The Black Eyes* provides a unique case to examine this intersection. Despite the novel’s rich narrative, which offers insight into Iraqi women’s lives, there is a lack of comprehensive CDA to understand how its language constructs
