Manufacture of a Horizontal Type Wind Turbine WIND MILL and Study of Its Characteristics in the Qayyarah Region
No full textThe main goal of our research is to design a windmill to withdraw and pump groundwater in agricultural areas where delivering electrical current is expensive and requires high voltage. We designed, manufactured, studied and described horizontal axis wind turbines, as the system was designed locally. It is considered one of the best options for low-speed winds. The turbine contains ten blades, the length of each blade is 1.2 meters, and the turbine area is 4,524 square meters, with the height of the wind turbine tower reaching 8 meters. The gearbox contains 2 gears, one of which is a small one consisting of 24 teeth called Driver and the large gear contains 120 teeth called Driving, where the conversion ratio is 5:1 in order to obtain a lower speed and greater torque. The best characterization of the system was studied at low wind speeds, as the turbine power depends on the wind speed. It is suitable for use in the Qayyarah district during the summer. The cost of this project is very low compared to other projects that are used to pump water. It is also considered important for reducing desertification and increasing investment
A study on Identification of Bacterial Isolated From ICU Induce Nosocomial Infections
No full textThe aim of this study was to identify bacterial isolates associated with nosocomial infections in Intensive Care Units (ICUs) in Basrah hospitals during the COVID-19 pandemic. The research involved the collection of 103 clinical and environmental specimens, including blood, urine, patient bed swabs, ICU instruments, and walls. Standard microbiological methods were used to identify the bacteria, followed by antibiotic sensitivity testing to determine resistance patterns. The results revealed 46 bacterial isolates, with Enterobacter species (42.55%), Staphylococcus species (34.04%), and Pseudomonas species (14.89%) being the most dominant. These findings highlight the significant level of contamination in ICU environments, which may contribute to the spread of nosocomial infections, particularly during public health crises like the pandemic. This study emphasizes the importance of implementing stringent infection control measures to prevent the spread of resistant pathogens in ICU settings, which is crucial for reducing healthcare-associated infection risks
A Statistical Study on the Most Important Factors Affecting Infant Mortality in Iraq
No full textInfant mortality remains a significant health challenge in Iraq and other developing countries, with approximately 40 deaths per 1,000 live births. This study aims to identify key factors influencing infant mortality in Iraq by analyzing World Health Organization data from 2010 to 2018. Despite existing efforts, there is limited understanding of how economic, social, and health conditions collectively impact infant survival. The research examined variables such as age, gender, health and nutrition status, and the socioeconomic conditions of families and communities. The findings reveal that poor health and nutrition, coupled with low socioeconomic status, are the primary determinants of infant mortality. The study suggests that improving maternal and infant health care, enhancing community health education, and addressing poverty-related challenges are essential for reducing infant deaths. Further research is needed to deepen understanding and develop targeted interventions
Disparities in Gender and Postponement in the Manifestation of Pediatric Strabismus
No full textThe primary aim of this research study was to meticulously evaluate and analyze the variances in gender-related differences as well as the delays in the presentation of childhood squint conditions within the context of a tertiary care hospital environment. This investigation was conducted through a comprehensive assessment of a cohort of pediatric patients who were diagnosed with squint and subsequently presented for medical attention at the Al hussain medical city in Karbala, Iraq,. We undertook a retrospective examination of the pertinent clinical cases that were recorded during the time frame spanning from February 2010 to July 2017, thereby allowing us to gather extensive data for our analysis. A study involving 214 children with squint found that 52.4% were female. Boys presented for treatment earlier, at an average age of 3 years and 5 months, compared to girls at 4 years and 5 months, with a significant p-value of less than 0.05. Girls also had longer delays in seeking treatment, with a median delay of 2 years and 3 months, while boys had a median delay of 1 year and 3 months. Amblyopia was observed in 25.3% of the children, with girls showing a higher, though not statistically significant, prevalence (P-value 0.09). In summary, our study revealed a significant gender disparity in the age at which children present with squint conditions, highlighting the need for further investigation into the underlying factors contributing to this phenomenon in our patient population
A Statistical Study of Stroke Patients
No full textStroke is a critical medical emergency characterized by a blockage of blood flow to the brain, which can result in irreversible damage and increased mortality risk. Despite widespread awareness of its symptoms—such as weakness in limbs, speech difficulties, severe headaches, and vision disturbances—there remains a knowledge gap regarding timely intervention and response strategies. This research aims to assess current understanding of stroke recognition and emergency response among the general public. Utilizing a mixed-methods approach, we surveyed and interviewed individuals to evaluate their knowledge and perceptions of stroke symptoms and urgency. Preliminary results indicate significant variability in awareness, highlighting a need for improved educational initiatives. The implications of this study underscore the importance of enhancing public knowledge to facilitate quicker emergency responses, ultimately reducing the incidence of long-term disabilities associated with stroke

No full textIn this paper, a detailed chemical analysis of the hydrodistillate of the above-ground part of the plant Melissa officinalis L. using gas chromatography with mass spectrometry (GC-MS) was carried out. The study showed that the hydrodistillate obtained from the above-ground part of Melissa officinalis contains a rich complex of bioactive compounds including terpenes, flavonoids, phenolic acids and other volatile substances. The major components identified include 1,4-Dioxaspiro[4.5]decane-7-butanoic acid, 6-methyl-, 2-(methylsulfonyloxy)ethyl ester (12.59%) and 2-octadeca-9,12-dienoxyethanol (8.59%). Analysis of the hydrodistillate composition also revealed the presence of compounds such as Dipalmitin, Ethyliso-allocholate and Glycine, N-[(3α,5β)-24-oxo-3-[(trimethylsilyl)oxy]cholan-24-yl]-, methyl ester. These data are important for standardisation and quality control of melissa-based phytopreparations and for the development of new therapeutic and cosmetic product
COMPARATIVE ANALYSIS OF STRUCTURAL AND FUNCTIONAL INDICATORS OF THE HEART IN PATIENTS WITH ATRIAL FIBRILLATION DUE TO MYOCARDIAL INFARCTION OF DIFFERENT LOCATIONS
No full textLarge epidemiological studies have shown that AF is associated with high mortality and adverse events in patients with AMI. However, the answer of this association is still not clear. According to the literature, atrial fibrillation (AF) complicates the course of myocardial infarction (MI) in 1213% of patients. The appearance of arrhythmia is associated with a worsening prognosis of the disease. Against the background of tachysystole , which often develops with AF, coronary blood flow is depleted and acute heart failure appears. The absence of coordinated atrial systole during fibrillation plays an important role in the development of hemodynamic complications, because the atrial component of diastole provides up to 25% of left ventricular (LV) filling. One of the main reasons for the development of AF during myocardial infarction is considered to be an increase in the hemodynamic load on the atrium with the development of acute left ventricular failure. Against the background of pressure overload, overstrain and stretching of the atrial myocardium occurs, which significantly increases its electrical instability. In addition to acute hemodynamic overload, the causes of AF include ischemia and damage to the atrial myocardium in the case of thrombotic occlusion above the origin of the arteries supplying the atria. After the cessation of the arrhythmia attack, as a rule, hemodynamics and coronary blood flow improve. However, in the case of persistent dysfunction of the left atrium (LA), the risk of distant reversion thromboembolism of the systemic circulation remains
