This study investigates the levels of gaseous and particulate pollutants (PM2.5, PM10, CO, and CO₂) emitted during charcoal-grilling activities in five selected restaurants in the Al-Karkh district of Baghdad, with a focus on their environmental and health implications. Developing countries, including Iraq, face severe pollution-related challenges exacerbated by inefficient combustion processes inherent to traditional cooking practices. Restaurants that rely on charcoal grilling are a significant source of both indoor and outdoor air pollution, posing acute and chronic health risks to workers and patrons. This research documented measured amounts of pollutants released from burning coal using two types of particulate matter (PM2.5; PM10) by checking each sample for the amount present during specific times (both day and night) over nine workdays in December 2024. Data indicate that very often, PM2.5 and PM10 measurements are substantially greater than the 24-hour guideline values set by both the World Health Organization (WHO) and the US Environmental Protection Agency (US EPA) -- especially on evening peak hours, with maximums of 211 µg/m³ and 212.8 µg/m³, respectively. Carbon dioxide levels were found to be well over 900 parts per million (ppm) at most of the sites checked, indicating very poor air quality from insufficient ventilation, and carbon monoxide (CO) levels were consistently over 35 ppm and as high as 83.0 ppm at night - which can lead to headaches, dizziness, problems with thinking/working, and if exposed to this for an extended time, heart disease. Temperature and relative humidity were both found to be in a thermally good zone; however, relative humidity was found to be 60 percent or more, which adds to increased health problems associated with the pollutants from burning coal, due to a much higher risk of growth of microorganisms. The researchers believe that there is a critical need to put in place effective pollution control measures; that high-efficiency exhaust systems need to be put in place; and there should be a collaborative effort by governmental bodies and restaurant owners to develop strong, enforceable policies for regulating emissions from burning coal and protecting public health in the food-service sector of Baghdad.
Multi-spectral satellite images of the Landsat satellite by the tow sensitive Thematic Mapper (TM) and Thematic Mapper Enhancement (ETM+), which covered the study area located south east of Iraq. In this research; used the sixth thermal spectral band (Thermal Band) for study the water cover in the AlRazzaza Lake located within the province of Karbala. We intended to study the cover a case of the study area, used satellite images showing the status of region during the period from 1990 to 2001 and 2007. From this study we conclude that cover the water of the study area change in sequence case to decrease during these years.

Gas-assisted gravity drainage (GAGD) has emerged as a promising enhanced oil recovery (EOR) method that utilizes the natural buoyancy of injected gas to mobilize oil in gravity-dominated systems. The scope of this work is to experimentally evaluate the performance of CO2-assisted GAGD in the presence of bottom-water support, a common reservoir condition that complicates gas flooding efficiency. The primary objectives are to (i) assess the impact of injection pressure and oil production rate on oil recovery, (ii) determine the operational conditions that maintain gravity dominance and delay breakthrough, and (iii) identify the trade-offs between maximizing recovery and minimizing ga
Analysis system of sports players is very important for individuals in weightlifting. Assessment of player and strength is important for the performance of weightlifting. This paper proposes an analytical method for weightlifters with check-by-frame video. This analysis system can compute the major steps of seven positions in both snatch and clean and jerk methods in frame-video weightlifting monitoring of movements. Each user can compute the major steps of the seven positions of Hu moments among two frames in the video during training, and the Euclidian distance can be computed for the Hu moment values and lifting moment values in the snatch and clean and jerk methods during training. The outcome of the proposed system shows on efficien

Lip reading is essential for speech recognition in noisy environments or for those with hearing impairments. It refers to recognizing spoken sentences using visual information acquired from lip movements. Also, the lip area, especially for males, suffers from several problems, such as the mouth area containing the mustache and beard, which may cover the lip area. This paper proposes an automatic lip-reading system to recognize and classify short English sentences spoken by speakers using deep learning networks. The input video extracts frames and each frame is passed to the Viola-Jone

Cobalt was used for producing a polymer metal complex and solution casting was used to produce a polymer blend including nano chitosan. All produced compounds have been characterized by FT-IR, DSC/ TGA, and SEM techniques as well as biological activity. The production of polyacetal is illustrated by the FT-IR analysis. The DSC/TGA results indicate the prepared polymer blends' thermal stability. Staphylococcus aureas, Klebsiella pneumoniae, Bacillus subtilis, and Escherichia coli were the four types of bacteria selected to study and evaluate the antibacterial activity of produced polyacetal, its metal complex, and polymer blend. Results indicates that ther
