    No full text
    In this study, the concentration of natural radionuclide activity, risk factors, and annual effective dose in 18 samples of consumer food in the city of Hilla were calculated using a gamma-ray detector due to the high degree of accuracy in the spectroscopic measurement of the detector. The average activity concentrations of 232Th, 238U, and 40K were found to be 9.67±0.149, 6.08±0.145, and 220.21±0.895 Bqkg-1, respectively. The average radium equivalent activity in all samples was calculated as 36.87 Bqkg-1, which is less than the permissible limit of 370 Bqkg-1. The average values of the external risk indicators and internal risk indicators for the food samples were 0.10 and 0.12, respectively, which are less than unity in all models, which indicates that nutritional models are not harmful. The average gamma hazard index (Iγ) was determined to be 0.28. The average annual effective dose equivalent was calculated as 135.67 μSvy-1, It is less than the permissible limits recommended by the United Nations Committee on the Effects of Radiation. Radiation is 1000 μSvy-1. These results may be useful for creating a database to evaluate the concentration of natural radioactivity in foodstuffs consumed in the city of Hilla

    A review of Water Quality and Pollution Assessment of the Euphrates River

    No full text
    Water contamination is widely acknowledged as a serious environmental problem, largely due to the rapid rise of human civilization and inadequate management of water resources. Due to its detrimental effects on ecosystems and public health, river and lake contamination—caused by trash from industry, agriculture, and residential sources—has gained significant attention in environmental and conflict studies. The purpose of this review is to assess the environmental changes in water quality along the Euphrates River from its source at the border between Turkey and Syria to southern Iraq. Identifying seasonal fluctuations in chemical concentrations, evaluating variations in the physical and chemical qualities of water, and improving the water quality database for academics are some of the main goals. Iraq's rivers, such as the Tigris and Euphrates, have seen a decline in water quality because of untreated waste discharge and climate change. The effects of critical water quality parameters on aquatic life and agricultural appropriateness are assessed. These factors include temperature, pH, total dissolved solids, and the concentration of components including sodium, calcium, magnesium, chloride, and sulfate. The review also looks at the hydrological and geological aspects of the Euphrates River, emphasizing the role of climate, groundwater, and rock formations. The construction of dams in Syria and Turkey has drastically decreased the river's discharge, making Iraq's problems with water quality worse. The study emphasizes the necessity of collaborative water management and environmentally friendly methods to lessen the negative impacts on the Euphrates River and guarantee the wellbeing of the region's population and ecosystems

    Assessment of Groundwater Recharge Under Changing Climatic Conditions in Alguwair Area, Northern Iraq

    No full text
    Water resources in the Alguwair region of Northern Iraq are largely dependent on groundwater, making effective management critical, especially under changing climate conditions. This study applied the SWAT model to estimate groundwater recharge and assess its sensitivity to climate variability. The model was calibrated and validated using hydrological data, and sensitivity analysis identified key recharge parameters. Results showed that shallow unconfined aquifers receive an average annual recharge of 350 mm, while deep confined aquifers receive 500 mm, influenced by hydrogeological characteristics and aquifer connections. Recharge contributed 34.4%-37.9% of total rainfall from 2016-2023, suggesting watershed characteristics, rather than rainfall variability, drive recharge patterns. These findings highlight the SWAT model’s utility in predicting sustainable groundwater management and could inform water resource policies for the region

    A Computational Study of the Properties of Pure, Adsorbed, and Doped Zinc Oxide With Copper and Nickel Atoms

    No full text
    Zinc oxide (ZnO), a promising n-type semiconductor with hexagonal-layered structure, has attracted significant attention due to its versatile applications in optical and electronic devices, including field-effect transistors, nanogenerators, LEDs, laser diodes, and solar cells. Despite extensive research on pure ZnO, the effects of doping with transition metals like copper (Cu) and nickel (Ni) on its electronic properties remain underexplored. This study investigates the electronic properties of pure ZnO, ZnO doped with Cu and Ni, and ZnO co-doped with Cu and Ni using Density Functional Theory (DFT) and the GGA-PBE approximation (CASTEP). Results reveal that Cu and Ni preferentially adsorb above oxygen sites on the ZnO surface, altering its electronic structure. Pure ZnO exhibited a band gap of 1.68 eV with a bond length of 1.89 Å. Upon Cu adsorption, the gap reduced to 0.11 eV with a bond length of 1.97 Å, while Ni adsorption resulted in a 0.862 eV gap and a 2.03 Å bond length. Doping ZnO with Cu eliminated the band gap, making it conductive with a bond length of 1.888 Å, whereas Ni doping narrowed the gap to 0.369 eV with a bond length of 1.85 Å. These findings underscore the potential of Cu- and Ni-doped ZnO for enhanced electronic applications by tuning the band gap, paving the way for advances in nanoscale device engineering

    Renewable energy is the only way to reduce global energy shortages. Solar is a high-yield renewable resource. Solar energy is becoming a major renewable energy source. Modern technologies include solar heating, photovoltaic, solar thermal energy, solar architecture, molten salt power plants, and artificial photosynthesis utilise solar light and heat. We represented the Dual Axis Solar panel with a 10W, 21V, 0.57 solar panel. We built a solar panel framework. Crafting the framework using cardboard cuts project costs. Trackers point solar panels at the sun. These devices rotate to follow the sun to maximum energy capture. Solar trackers can boost electricity generation by a third or even 40% in some countries compared to fixed-angle modules. When modules are constantly adjusted to the optimal angle as the sun moves, solar conversion efficiency improves. This paper designs an Arduino UNO-based Dual Axis Solar Tracking system to move solar panels toward maximum sunlight. The fixed solar system could maximise solar panel production by improving efficiency. LDRs send a signal to the Arduino UNO, which sends it to the servo motor connected to it, which positions the Axis Solar Panel in the sun's direction. This allowed Arduino UNO to track dual-axis solar panels with maximum power. Our technology is more efficient, small, low-cost, and easy to use. &nbsp

    This study investigates the relationship between maternal blood zinc levels and preterm birth outcomes. Recognizing that zinc deficiencies in pregnant women correlate with various pregnancy complications, this research aimed to clarify zinc's impact on preterm delivery. Using a case-control design, zinc levels were measured via spectrophotometry in 138 pregnant women, including 76 who delivered prematurely and 62 who delivered at term, at Abi Ghraib General Hospital from February 2018 to September 2019. Results indicated a significantly lower average blood zinc concentration in the preterm group (39.62 µg/dL) compared to the term group (59.81 µg/dL) (P < 0.001). Additionally, women experiencing membrane rupture had lower zinc levels (43.06 µg/dL) than those who did not (50.46 µg/dL) (P = 0.01). No significant correlation was found between zinc levels and parity (P = 0.634). The study highlights the critical prevalence of zinc deficiency among expectant mothers and suggests that addressing micronutrient deficiencies through targeted nutritional interventions could improve maternal and neonatal health outcomes
