Al-Razzaza Lake is one of the most important water resources in Iraq, holding significant economic and environmental value for the country. The lake is now undergoing significant ecological changes and experiencing water level declines, primarily driven by increased evaporation due to climate change and reduced inflow from the Euphrates River. It is, therefore, important to monitor the changes affecting the lake using remote sensing and geographic information systems (GIS). This study aims to assess environmental changes in Al-Razzaza Lake by analyzing Landsat 4-5 images for 2004 and Landsat 8-9 images for 2014 and 2024. Climate data were obtained from the NASA Energy website (2004 and 2014) and the Al-Razzaza station of the Ministry of

In this study, reduced graphene oxide (rGO) was synthesized from graphene oxide (GO) via an ascorbic acid-assisted reduction process. GO was synthesized from graphite powder using a modified Hummers technique. The surface morphology, structure, functional groups, and elemental compositions of the produced materials were studied using various methods, such as scanning electron microscopy (SEM)/EDX, X-ray diffraction (XRD), atomic force microscopy (AFM), Fourier transform infrared (FTIR), and UV-Vis. The removal of oxygen-containing functional groups in rGO through reduction resulted in poor sample quality. In addition, FTIR investigations revealed that GO contained more oxygen-containing functional groups than rGO. Typical peaks at 26.708

This study methodically investigates the correlation between plasma parameters and the structural properties of Ni nanoparticles synthesized using pulsed laser ablation in liquid (PLAL) at varying laser energies (600 - 900 mJ). Optical emission spectroscopy (OES) revealed that increasing laser energy enhanced plasma ionization with electron temperature (T_e) rising from 0.262 to 0.334 eV, and electron density (n_e) increased from 5.00×10¹⁸ to 5.63×10¹⁸ cm⁻³ through intensified collisional excitation. Plasma parameters directly influenced the variation in crystallite size and morphology, demonstrating that higher plasma temperatures and densities en

Oil extraction is a crucial industry for Iraq, significantly contributing to the country's economy, particularly in Basra Governorate. However, intensive extraction activities can lead to ground deformation, manifesting as subsidence and uplifts, which may impact infrastructure and the environment. This study investigates ground deformations caused by oil extraction in the Rumaila oilfield, one of Iraq's major oil-producing areas, located in southern Iraq. The study employed Differential Interferometric Synthetic Aperture Radar (DInSAR) techniques using Sentinel-1 SAR data from the European Space Agency. To analyze these deformations, DInSAR allows for precise measurement of surface deformation by calculating displacement differences bet

This study outlines a technique for enhancing a metal oxide semiconductor gas sensor's sensitivity to nitrogen dioxide (NO₂) gas. Using a sol-gel and spin-coating process, the gas sensor was constructed from hydrothermally generated ZnO nanorods (ZNRs) and decorated with different concentrations of CuO nanoparticles (NPs). Field-emission scanning electron microscopy (FE-SEM), X-ray diffraction, and optical characteristics were used to examine the gas sensor's morphology, crystal structure, and UV-Vis absorption. The primary pattern's hexagonal structure was revealed by X-ray diffraction and FESEM images, which showed the rough surface of ZNRs/CuO NPs. NO₂ gas-sensing characteristics were examined at three different CuO NP c

Thermal conductivity of compacted bentonite is one of the most important properties where this type of clay is proposed for use as a buffer material. In this study, Lee's disc method was used to measure the thermal conductivity of compacted bentonite specimens. The experimental results have been analyzed to observe the three major factors affecting the thermal conductivity of bentonite buffer material. While the clay density reaches to a target value, the measurement is taken to evaluate the thermal conductivity. By repeating this procedure, a relationship between clay dry density and thermal conductivity has been established in specimens after adjusting the water contents of the bentonite by placing its specimens in a drying oven for diffe

In recent years, the deployment of surveillance cameras has significantly increased to enhance security in public and private spaces. Numerous businesses continue to employ individuals to monitor these cameras. However, unusual and suspicious activities in the video feeds are often overlooked due to the potential for human error. Consequently, manual monitoring of security cameras can be time-consuming and inefficient. This study investigates the application of deep learning techniques, particularly convolutional neural networks (CNNs) and support vector machines (SVMs), to predict violence in surveillance video streams. The proposed CNN model is optimised through the utilisation of gamma correction as a preprocessing step to extract ess

This study investigates the influence of structural geometry, elastic modulus, mass density, and section dimension uncertainty on the stochastic earthquake response of portal frames subjected to random ground motions. The North-South component of the El Centro earthquake in 1940 in California is selected as the ground excitation. Using the power spectral density function, the two-dimensional finite element model of the portal frame’s base motion is modified to account for random ground motions.

Background: Substance use disorders (SUDs) are among the common psychiatric disorders and constitute a major public health concern. Iraqi’s were exposed to widespread violence and wars in the last decades. High prevalence of alcohol and substance use was reported recently in Baghdad. Research literature documented the association of SUDs with exposure to trauma events e.g. wars, terrorist attacks and natural disaster. Published articles on SUDs among prisoners in Iraq are scarce. Therefore, this work was carried out to report on SUDs among prisoners in Al-Diwania governorate and its relation to antisocial activity.
Methods: A total of 1200 prisoners in Al-Diwania civilian prison were included in the stu
