For many individuals, heavy metal persistence and toxicity are severe problems. Most of these heavy metals collect in wastewater from effluents discharged by various industries. The efficient re-use of these particles as catalysts is another new development in research that complements the success of hazardous metal particle removal. Five locations along the Euphrates River in western Iraq’s Anbar Governorate were the subject of the research (Husaibah Al-Sharqiah, Al-Karābilah, Barwana, Al-Garma, Al-Forat sub district) and for four seasons (Summer, Autumn, Winter, and Spring) from November 2021 to November 2022 in order to examine how the physical and chemical characteristics of the water in the Euphrates River vary over space and time in these areas. Based on these locations of garbage, contaminants, and heavy metal components that may flow into the river without environmental management, sampling locations on the Euphrates River were chosen. In order to better understand the distribution of heavy metals (HMs: Arsenic (As), Antimony (Sb), Selenium (Se), Molybdenum (Mo), Cyanide (CN-), and Chromium (Cr) in river sediments, five locations in western Iraq were chosen for the research. The PH, electrical conductivity (EC), algaes, and sediments (Nitrate (NO3), sulfate (SO4), and HMs content) were all measured in the river’s edge water. A qualitative research was also carried out at various times of year and locations. 104 different kinds of algae were found, and some of them dominated all the research locations. In each station near the beginning of the estuary, the quantitative research revealed a rise in the number of algae species indicative of pollution, confirming that these sites are impacted by the pollutants from untreated sewage discharged into the Euphrates River in those locations. The average concentrations of HMs and compounds in the sediments were as follows: SO4> NO3>Mo>Cn>Cr>Sb>Se>As. According to the investigation, the HMs polluted cities in the following ways: Sediment concentrations are greater in Husaibah Al-Sharqiah, Al-Karbilah, Barwana, Al-Garma, and Al-Forat subdistrict cities.

“…The programs (SPSS) were used to do the analysis of Variance (ANOVA) test which is significance of the differences in the measured characteristics was determined using the analysis of variance method [21][22][23][24][25]. The test is the presence or absence of significant differences in the studied variables (physical and chemical properties, according to the variables (spatial differences between locations and temporal differences between four seasons) [26][27][28][29][30]. In addition, arithmetical average (M), Standard deviation (SD), Least Significant Difference (L.S.D.…”

Heavy metal toxicity and persistence are becoming major issues for people. These heavy metals mostly gather in wastewater from effluents released by different industries. The effectiveness of hazardous metal particle removal is currently just one recent trend in research; another is the efficient re-use of these particles as catalysts. The study was conducted for five sites on the Euphrates River in Anbar Governorate, western Iraq (Al Muḩammadī, Al-Khalidiya, Al-Habbaniya, Al-Saklawiya, Amirya Al-Falluja) with four stations for each site (the beginning of the estuary, after the estuary and before the estuary) and for four seasons (Summer, Autumn, Winter and Spring) from October 2021 to October 2022 to study spatial and temporal variation on the physical and chemical properties of the Euphrates River water in these locations. Sampling sites on the Euphrates River were selected based on these sites of waste, pollutants and heavy metal components that may flow into the river without environmental control. So, the study aimed at investigating the distribution of heavy metals (HMs: Manganese (Mn), Iron (Fe), Nickel (Ni), Copper (Cu), Lead (Pb), Cadmium (Cd)) in the sediments of the river for five sites in the west of Iraq. In the edge of the river (water) the Hardness, Salinity, algaes have been examined and for (sediments) the compounds (nitrite (NO2) and Sulfate (SO4)) and HMs concentration were measured too, and a qualitative study was conducted during the different seasons and sites. 79 types of algae were identified and some species prevailed in all studied sites. The quantitative study showed an increase in the number of algae species indicative of pollution in the sites in each station (the beginning, before and after the estuary), which confirms that these sites are affected by the untreated sewage pollutants thrown into the Euphrates River in those sites. The average concentrations of HMs and compounds in the sediments were as follows: SO4> NO2>Mn>Fe>Cu>Ni>Pb>Cd. The analysis showed that the pollution of cites by the HMs was as follows Al Muḩammadī, Al-Khalidiya, Al-Habbaniya, Al-Saklawiya, Amirya Al-Falluja cites concentrations are higher in sediments.

“…For a theoretical analysis of the processes occurring in PV installations with various switching options for solar cells operating in conditions of uneven illumination, a mathematical model of a solar cell was compiled, with an accuracy sufficient for engineering calculations-not exceeding the design tolerance. Thus, the initial mathematical model describing the operation of the solar cell model is as follows [19][20][21].…”

This article is devoted to the relevant problem of increasing the efficiency of PV systems. The presented analysis discusses the available methods for improving the power generation of PV modules under partial shading. Mathematical models for power loss calculation were compiled based on the results of this analysis. The proposed approach minimizes the negative impact of partial shading on the energy production of PV modules. It is based on the equalization of voltages of parallel-connected arrays of modules by installing additional power elements in them. The proposed solution is promising for various areas; it allows for the minimization of the unfavorable influence of existing urban objects (buildings, trees, communications, etc.) on the energy efficiency of PV modules. The obtained results are useful for the sustainable development of the urban environment in the context of digital transformation. They are the basis for the promising methodology of the parametric optimization of power plants using renewable energy sources.
