This review offers an overview of key developments that may assist researchers in improving thermal management strategies for photovoltaic systems across different environmental conditions. It's worth noting that temperature significantly affects the efficiency of photovoltaic systems. As operating temperatures rise, energy production decreases, impacting the system's lifetime. The main focus of this research paper, which examines recent developments in thermal management technologies for photovoltaic systems, is the use of fin-based cooling technologies. he efficiency of passive, active, and hybrid cooling technologies was evaluated, focusing on their ability to dissipate heat and increase the efficiency of photovoltaic

Radiation is the emission of energy in the form of particles or photons, and it has two types: cosmic radiation and terrestrial radiation. Materials that emit radiation as they decay over time are called naturally occurring radioactive elements. This study, which was conducted at the Asalah site after removing radioactive contamination, included taking 15 samples from different locations at the site and conducting radiological tests on them using the HpGe (high-purity germanium) system available at the laboratory of Iraqi Atomic Energy Commission- Radiological and Nuclear Applications and Laboratories Directorate From this study one can see that the average value of specific activity for ²²⁶Ra was 15.51 Bq/kg,

This paper proposes a novel control strategy for a Unified Power Quality Conditioner (UPQC) to effectively mitigate voltage and current disturbances in three-phase four-wire (3P-4W) systems. Existing UPQC control approaches often struggle to address unbalanced load conditions, resulting in significant power quality degradation. This research addresses this gap by introducing a fast fuzzy logic (FFZ) controller, which, in comparison to traditional PI controllers, offers enhanced performance in managing DC voltage fluctuations and generating accurate reference currents for the shunt active filter. The proposed FFZ controller effectively minimizes the impact of unbalanced loads on DC voltage, reducing error and improving ov

Environmental quality for a healthy life is a major focus of scientific studies on human life and health. Rapid economic growth and urbanization have exposed major cities such as Baghdad to the risk of environmental problems, including desertification, air and water pollution, and high greenhouse gas emissions. These risks can be studied and assessed using Geographic Information Systems (GIS), which provide a comprehensive understanding of environmental issues and evidence-based remedies. Focusing on water and air pollution, this study will examine and assess environmental risks in Baghdad. The study identified areas with high concentrations of PM10, NO₂, and SO₂ through analyzing GIS maps. These ar

This research aims to co-register UAV (Unmanned Aerial Vehicle) photogrammetry and Terrestrial Laser Scanning (TLS) for volumetric measurements of irregularly shaped material stacks available at construction sites in Iraq. The research investigates the potential of combining these techniques in comparison to standalone and traditional techniques to improve volume quantification and time consumption. An area containing a stockpile of bulk materials and building remnants was selected. A low-cost drone was used for data acquisition, whereas Structure from Motion (SFM) and Multi View Stereo (MVS) algorithms were used for processing and analysing the photogrammetric data. In contrast, Stonex X300 TLS device was used for laser

Nigeria's limited freshwater resources are at risk due to the discharge of wastewater from water-intensive industries, such as food processing, that does not comply with the regulations of the National Environmental Standards and Regulation Enforcement Agency (NESREA). This could significantly harm both the ecosystem and human health. This study aims to assess the physicochemical and biological properties of wastewater discharged from selected bakeries in Benin City, Nigeria, to determine compliance with NESREA standards and highlight potential environmental risks. Wastewater samples were randomly collected from five bakeries in Benin City and examined for their physicochemical and biological features. The findings indic

The research focuses on how to reach a mechanism that assists experts, engineers, and others in the architectural & engineering project to verify the co-existence of values and sustainability constituents in it. Research problem shows a clear lack, locally, in the interest to establish a value system and a list that cares about comprehending building components whether considering sustainable building criteria. Hypothesis shows that in order to head towards the applicable sustainable approach of buildings, then a local assessment system should be established to evaluate buildings during its life cycle, and from which buildings would be categorized as sustainable or not. Research aims at establishing main and general

Sports skills in some individual games require physical and motor qualities to facilitate the process of skill performance and also require the instructor or trainer to use more than one strategy, method and way to bring the performance to the level of mastery and avoid injury. The aim of the research is to know the effect of using special exercises using tools and their effect on teaching the skill of a front shoulder circle. The research hypothesis is that using special exercises with tools has a positive effect on teaching the skill of a front shoulder circle on the rings apparatus. Research method: - The researchers used the experimental method by designing two equal groups, the control and the experimental, to suit the research
