120 samples were collected from different clinical samples including swabs from wounds, noses, and pimples, blood, CSF, and medical equipment (catheters for dialysis and heart valves), among different age groups and sexes, from Gazzi Al-Hariri Hospital and Baghdad Teaching Hospital, during the period from Dec. 2022 to Aug. 2023. The ages from 10 to 65 years old were the range of the study. According to the results, 73 (60.83%) of the samples tested positive for Staphylococcus epidermidis, and the 47 females (64.38%) were more infected than the 26 males (35.61%). The age group of (36–50 years) showed a considerable increase in the infection ratio, followed by (25-35 years), then the age group of (51-65 years) and (10-24 years). The current study was performed in Baghdad Teaching Hospital/Department of Bacteriology. Differential and specific culture media were used to confirm the isolated clinical specimens. Virulence factors and biochemical tests were performed. The diagnosis was verified with the Vitek 2 system. Antibiotic sensitivity testing was achieved by applying the disk diffusion method. Ten S. epidermidis isolates were chosen, and their DNA was extracted and amplified using PCR to detect and validate the presence of the (mecAand ermA) genes. The current study used male mice as a model to perform the lethal dose (LD50). The mice weighed between 22 and 30 g and were between the ages of 2 and 3 months. And in the College of Veterinary Medicine, the mice were sheltered in the animal house. The mice were treated with the bacterial suspension that was adjusted to 0.5 McFerland standard, while, the control group was treated with phosphate buffer saline (PBS), and the mice were daily monitored. The mice exhibited transient behavioral abnormalities, decreased movement, and lethargy when compared with the control group. The skin showed pictures of severe dermatitis. When the mice died, their affected skin, liver, intestine, and heart were taken and preserved in the formalin to send them to the laboratory of histopathology. The histopathology techniques were performed in the histopathology laboratory-College of Veterinary Medicine. Normal cytoarchitecture and appearance were seen in the histopathology figures of the control group. While, the figures of the histopathology of the injury group showed severe hepatitis, severe myocardial infarction, severe enteritis, and the skin appeared with severe dermatitis.

Energy supply and waste management are becoming increasingly important for Iraq and the Middle East. Population growth, rapid urbanization, and economic development have increased waste generation. In addition, when energy demand exceeds supply, it leads to frequent power outages. Waste-to-energy is a new approach that offers environmental, economic, and security benefits by integrating waste treatment with clean energy production. This paper examines several waste-to-energy methods in Iraq today, including gasification, incineration, and others. These technologies have the potential to reduce global greenhouse gas emissions, increase local and sustainable energy sources, and reduce the amount of garbage that ends up in landfills. Strategies for waste-to-energy are also discussed, as are the challenges facing waste-to-energy programs in Iraq. The role of the world and the Middle East in waste-to-energy, especially electricity, is also discussed. In addition, future prospects for Iraq are highlighted, including strengthening government initiatives, the possibility of international cooperation, and utilizing large amounts of waste as a resource for energy generation. Several suggestions have been made to improve the method waste-to-energy projects are implemented in Iraq. These suggestions include developing a strong infrastructure for waste management and energy conversion, using appropriate and advanced waste-to-energy technologies, such as electricity. Also, efficient policies and regulations should be enacted to support waste-to-energy. Iraq can also seize the opportunity to develop strategic partnerships with international companies specialized in environmental technology and waste-to-energy and also focus on marketing and awareness to enhance community awareness of the benefits of waste-to-energy and electricity generation, which would encourage increased investment projects in this field.

This paper aims to explore the role of Artificial Intelligence (AI) in improving the environmental and economic analysis of the life cycle of green hydrogen production. The study includes a presentation of how AI can be used to collect and analyze data, model future scenarios, improve process efficiency, and manage risks. Green hydrogen is one of the most promising solutions to achieve sustainability and clean energy goals, but its production requires advanced technology and high efficiency. The study used a multi-level approach that includes a literature review, experimental data analysis, and the application of predictive models and simulations, with a focus on practical applications of AI in the life cycle stages. The study showed that AI can improve the accuracy and effectiveness of data collection, build advanced predictive models, and experiment with scenarios to determine the best environmental and economic options. AI also has the potential to improve the efficiency of production processes by optimizing resource allocation and reducing waste, which increases the productivity of electrolyzer. In addition, AI has contributed to the effective assessment and management of risks, which helps in making informed decisions. AI tools have provided advanced graphical visualizations and data-driven recommendations, which facilitate the decision-making process and enhance sustainability. The study finds that AI plays a crucial role in enhancing the efficiency and sustainability of green hydrogen production and recommends further research and development in this area to achieve global sustainability goals.
