The purpose of this paper was concerned of the behavior of six samples of deep beams under the influence of pure torsion. Such samples were self-compacting concrete (SCC) and two ratios of Steel Fibers (SF (were also added (0.75 % and 1.5 %). This study examined the behavior of the samples when pure torsion was applied and reacted to angles of torsion, longitudinal strains and concrete strains. It was obvious from the results of the test that the addition of steel fiber to the SCC mixture increased the strength of the compression and tensile strength, which increased the hardness of the samples, thereby decreasing the response of the samples to the angle of twisting, longitudinal strains of concrete and concrete strains.

Background: Not many studies have investigated the knowledge outcomes among medical students with regards to contact lenses (CL). Thus, in this study, we aim to assess the attitude and awareness of CL use and the associated factors among medical students of King Faisal University (KFU), Al Ahsa, Saudi Arabia. Methods: This a cross-sectional study that based developed based on a designed questionnaire that was composed of 31 questions with a maximum score of 57 points. We have also conducted a linear regression model to explore the possible important factors that may affect the level of knowledge and awareness about contact lenses care. Results: A total of 208 participants were included in this study, with a mean age of 21.0 ± 1.9, and 56.3% (n = 117) of them being females. The total mean knowledge score in our study was 30.1 ± 7.74, which was higher in females (31.5 ± 7.09) than in male participants (28.7 ± 7.69). The results of the linear regression model showed that being female (E = -0.37; 95%CI = -0.65— -0.10; P = 0.007), using contact lenses (E = 0.56; 95%CI = 0.29 — 0.82; P < 0.001), and in the third year (E = 0.66; 95%CI = 0.19— 1.13; P = 0.007) is significantly correlated with having higher knowledge scores about using CLs. Conclusion: Female participants had higher total mean knowledge scores than males. We recommend that further educational campaigns should be inaugurated to raise awareness about taking care of CLs and enhancing the related practices of wearing them.

The presented study has the aim of finding out the relationships between input variables and process parameters that describe mathematical models, also to estimate the impact of independent parameters on the Heat Affected Zone (HAZ). In the presented paper, A2-Tool Steel material is the utilized workpiece material, whereas copper is the electrode material. RSM, which is the abbreviation of Response Surface Methodology, is used for identifying the impact of controllable parameters; such controllable effects consist of pulse current, pulse on time, and pulse off time on HAZ. It has been noticed that model has been developed by RSM adequacy is suitable since the coefficient related to the determination is considered closest to one for HAZ, whereas the highest percentage of error between experimental and predicted data is (-13.829%). From ANOVA, the pulse current has the most significant factor affected on HAZ with 67.219% contribution.

BACKGROUND: Owing to the rising population of the Kingdom of Saudi Arabia, the need for family physicians is growing. The number of family physicians who would be available in the health service in future is dependent on the attitudes of medical students because their choice of specialty is a major factor in satisfying this demand. The aim of the study was to evaluate the attitudes of medical students to family medicine as a future career. MATERIALS AND METHODS: This cross-sectional study was conducted at King Saud Bin Abdulaziz University for Health Sciences. A total of 308 students were randomly selected from problem-based learning groups. Data were collected using a 25-item validated questionnaire, and Excel and SPSS were used for data entry and analysis. Mean and standard deviation were used to describe numerical data and frequencies and percentages to describe categorical data. P < 0.05 was considered statistically significant. RESULTS: A total of 308 medical students, 201 (65.3%) of whom were male, completed the questionnaire. Majority of the students (229 [74.3%]) agreed that family physicians make important contributions to medicine although family medicine was one of the least preferred specialties of the students. CONCLUSIONS: Most students were aware of the importance of family medicine; however, only a few of them chose this specialty. Further studies should be conducted to identify the factors that influence medical students' decisions in their choice of family medicine as a future career.

Chemical machining is a well-known nontraditional machining process and is the controlled chemical dissolution of the machined work piece material by contact with a strong acidic or alkaline chemical reagent. It is also called as chemical etching. The present work is aimed at studying the effect of machining time, machining temperature, etching solution concentration on the surface finish of stainless steel 304 using mixed of acids (HCL+HNO3+HF+ H2SO4+H2O). Alloy samples are of (33×33×6) mm dimensions. Three machining temperatures (45, 50 and 55 ºC) for each of which three machining times (3, 6, and 9 min) were used as machining conditions. Surface roughness increases with the machining temperature and machining time. An assessment of CHM was achieved by empirical models for selecting the appropriate machining conditions of the required surface finish. The models were designed based on multiple regression method via Mtb 16 software.

Introduction: Bird attacks are in general an uncommon event. To our knowledge, this is the first reported case in Bahrain. There have been very few cases reported worldwide. Mainly, birds attack humans as retaliation to threats surrounding their environment. At certain occasions, bird attack frequency increases especially during mating season or in the presence of a threat toward their young. Methods: A 31-year-old male presented with a history of left-eye trauma, loss of vision, pain and tearing for 2 hours. A left corneal penetrating laceration and traumatic cataract were diagnosed. The corneal laceration was closed surgically, the lens was aspirated and anterior vitrectomy performed. Results: After 4 months of follow-up, penetrating keratoplasty and posterior chamber intraocular lens implantation were performed elsewhere. The patient's vision improved from hand motion in his left eye to 20/200 without correction. Conclusion: Corneal perforation secondary to a bird injury can be treated successfully with surgical closure and broad intravenous antibiotic coverage. This rare type of ocular trauma does not require any specific additional measures.

All Distributed association rules mining (DARM) algorithms which bases on Apriori algorithm don't have an efficient message optimization technique, so they exchange numerous messages during the mining process which needs several distributed scan operations to the distributed warehouses or distributed databases to get the support values, also the performance of these DARM algorithms decreased with increasing communication cost especially when increasing the number ofdistributed mining sites as well as the itemsets to be mined become more larger . The aim of this work is to improve association rules in distributed data mining by proposing a new efficient method of distributed association rule mining, which reduce the average size of records transferred, datasets and messages transferred without needto any distributed scan to the distributed data warehouses or distributed databases to retrieve the values of the support values of these datasets. The results obtained from the proposed method prove that the proposed method is better than the existing algorithms by reducing communications costs, centralstorage requirements, enhanceperformance and achieves high degree of scalability compared with the existing algorithms.

Inthis work clustering optimization includes segmenting the image to find regionsthat represent objects or meaningful parts of objects depending on the abovementioned three features which base on gray value of image and two standardmathematical theories these are chessboard distance and breshenham's algorithm.There are many recent researches in this subject some of them depending on grayvalue feature to clustering images, but in this research depended on three featureswhich is making the clustering operation more accuracy.

This study is an experimental investigation of the effect of bioethanol gasoline blending on exhaust emissions in terms of carbon dioxide CO2, carbon monoxide CO, unburnt hydrocarbons UHC, and nitric oxide NOx of a spark ignition engine. Tests are conducted at controlled throttle and variable speed condition over the range of 1200 to 2000 rpm with intervals 400 rpm. Different compression ratios are tested for each speed, namely (7,8,10, and 11). Pure gasoline and bioethanol gasoline blends are used. The bioethanol used is produced from Iraqi date crop (Zehdi). Blending is done on energy replacement bases. Ethanol energy ratio (EER) used is 5%, 10%, and 15%. At each of the three designated engine speeds, the torque is set as 0, 3, 7, 10, and 14 N·m. It is found that ethanol blending reduces CO and UHC concentration in the exhaust gases by about 45% and 40.15%, respectively, and increases NOx and CO2 concentrations in the exhaust gases by about 16.18% and 7.5%, respectively. It is found also that load and speed increase causes an increase in CO2 and NOx concentrations and reduces CO and UHC concentrations. It is also found that increasing the compression ratio causes the emissions of CO2 and NOx to decrease and those of CO and UHC to increase.

In this paper we describe the causes, patterns of presentation, and management of obstructive uropathy in Sudanese patients in a retrospective multi-center audit. All patients who presented with obstructive uropathy during 2005 were included in this study. All of the patients were subjected to serial investigations including imaging and tests of renal function. Diversion, stenting, and/or definitive surgery were performed in order to relieve the obstruction. Five hundred twenty patients were diagnosed with obstructive uropathy during this period; 345 (66%) patients presented with chronic obstruction and 175 (34%) with acute obstruction. Of the study patients, 210 (40%) presented with significant renal impairment; 50 (23%) of them required emergent dialysis. The patterns of clinical presentation of the obstructed patients included pain at the site of obstruction in 48%, lower urinary tract symptoms in 42%, urine retention in 36.5%, mass effect in 22%, and anuria in 4%. Patients in the pediatric age group constituted 4% of the total. The common causative factors of obstruction included congenital urethral valves, pelvi-ureteral junction obstruction, urolithiasis, and iatrogenic trauma, especially in the obstetric practice. Renal function was completely recovered with early management in 100% of patients with acute obstruction and was stabilized in 90% of patients with chronic obstruction. Four patients were diagnosed with end-stage renal failure; two of them were transplanted. The mortality rate in this study was less than 0.3%.

This report describes a case of cortical blindness that followed successful surgical repair of two stab wounds in the heart in a 29-year old Libyan man. The patient presented in a state of pre cardiac arrest (shock and low cardiac output status), following multiple chest stab wounds. Chest tube was immediately inserted. Surgery was urgently performed suturing the two wounds; in the root of the aorta and in the left ventricle, and haemostasis was secured. Cardiac arrest was successfully prevented. The patient recovered smoothly, but 24 hours later he declared total blindness. Ophtalmic and neurological examinations and investigations that included fundoscopy, Electroencephalograms (EEGs) and Computed Tomography Scans revealed no abnormalities, apart from absence of alpha waves in the EEGs. We diagnosed the case as cortical blindness and continued caring for the patient conservatively. Three days later, the patient regained his vision gradually and was discharged on the 7th postoperative day without any remarks.

Introduction: The war caused huge devastation to rehabilitation centers in Mosul City, leading to a significant gap in rehabilitation services, which was further compounded by the COVID-19 pandemic. Objectives: We sought to incorporate simple and safe clinical exercises by utilizing common household items, thereby maximizing effectiveness through a combination of psychological simulation and physical impact while ensuring safety, and evaluate its efficacy as a home telerehabilitation program (HTRP) for participants with spinal cord injury (SCI) following a 4- to 5-year rehabilitation interruption. Methods: Eighteen volunteers, including 13 with SCI (injuries sustained 53.4–55 months prior), were split into an experimental group (Exp., n = 8), a first control group (first Con., n = 5), and a second control group of healthy individuals (second Con., n = 5), averaging 21.2 years old. The HTRP focused on muscles and whole-body joints, conducted with five weekly sessions gradually increasing from 45 to 120 min, with sufficient rest. Assessments occurred every 3 months. Results: The Friedman test indicated no significant effect of HTRP on weight, body mass index, 3 of 4 anthropometric measures, and 4 of 19 muscle strength tests, p > 0.05, and small effect sizes (ES). However, significant effects were observed in pelvic strength (p < 0.001, ES = 0.73), exceeding control groups (first Con. 1.6%, second Con. 1.0%). Muscle strength in the lower extremities, head, and trunk showed significant improvements (p < 0.05, ES = 18.3–81.8%), it is indicating functional enhancement despite morphological weaknesses, particularly in individuals with SCI. Conclusion: The HTRP demonstrated weak effects on muscle morphology but strong effects on functionality, highlighting its potential for long-term management and improvement of muscle functional outcomes in individuals with SCI, even after prolonged rehabilitation interruptions.

Introduction: The significance of comprehensive investigations specifically addressing the characteristics and implications of nervous system injuries (NSIs) and particularly war-related spinal cord injuries (SCI) remain limited. Iraq lacks comprehensive survey studies for quality of life for people after SCI. The objective of this work was to identify the number of NSIs and mortality of those injured during the Islamic State of Iraq and Syria (ISIS) war in Iraq and analyze events specifically as sociodemographic variables to assess quality of life healthy, psychological, and social disorders from onset of injury till the involving. Methods: A survey-based descriptive study, and analytical retrospective at community-based of Nineveh Governorate, in Iraq. The participants were 34 survivors of ISIS war with SCIs, ages between 9 and 60 years, and 7 females (20.59%) and 27 males (79.41%) as registered in Nineveh Center of Disability Rehabilitation. Data collection was conducted using Telephone Video Interviews and respondents' health information. Protocol-specific questions and some psychological and social scales (PTSD) (DSM-IV), (TAS-20), (SWLS), and (MSPSS) were also used. Results: There were 2,990 NSIs with the highest rate of injuries occurring from 2017 to 2018, and the SCIs were 267 injuries (8.93%), and (70.59%) at level T the mortalities were 57 cases, all participants suffered from physical and psychological chronic complications, while the results of the PTSD, GPC, and SWLS were at a moderate level. Conclusions: In urban warfare, there's a rise in NSIs, notably SCIs influenced by the type of weaponry. The survivors face significant physical, psychological, social, and financial burdens. More research is crucial to understanding their situations and developing strategies to alleviate their health, social, and financial challenges. [ABSTRACT FROM AUTHOR]

Air pollution is a serious issue that has an impact on human health all over the world. Improving air quality is a main part of environmental sustainability, and it begins with identifying contaminants and their sources. This paper examines air quality in urban areas and the background levels of pollutants in Kuwait by analyzing pollutant data from a number of fixed monitoring stations managed by the Environment Public Authority in the State of Kuwait. The concentrations of SO2, CO, O3, NO, and PM10 were measured at several sites in Kuwait. This study examines time series and wind rose plots for temporal and spatial variation, and pollutant sources. The results of this study show different variation patterns for SO2, which could be linked to traffic levels. There were similar daily profiles for CO, NO, and O3 at all the sites. Most of these pollutants exceeded the limits set by air quality standards. [ABSTRACT FROM AUTHOR]

Abstract Antibodies are essential to immune homeostasis due to their roles in neutralizing pathogenic agents. However, failures in central and peripheral checkpoints that eliminate autoreactive B cells can undermine self-tolerance and generate autoantibodies that mistakenly target self-antigens, leading to inflammation and autoimmune diseases. While autoantibodies are well-studied in autoimmune and in some communicable diseases, their roles in chronic conditions, such as obesity and aging, are less understood. Obesity and aging share similar aspects of immune dysfunction, such as diminished humoral responses and heightened chronic inflammation, which can disrupt immune tolerance and foster autoantigen production, thus giving rise to autoreactive B cells and autoantibodies. In return, these events may also contribute to the pathophysiology of obesity and aging, to the associated autoimmune disorders linked to these conditions, and to the development of immunosenescence, an age-related decline in immune function that heightens vulnerability to infections, chronic diseases, and loss of self-tolerance. Furthermore, the cumulative exposure to antigens and cellular debris during obesity and aging perpetuates pro-inflammatory pathways, linking immunosenescence with other aging hallmarks, such as proteostasis loss and mitochondrial dysfunction. This review examines the mechanisms driving autoantibody generation during obesity and aging and discusses key putative antigenic targets across these conditions. We also explore the therapeutic potential of emerging approaches, such as CAR-T/CAAR-T therapies, vaccines, and BiTEs, to tackle autoimmune-related conditions in aging and obesity.
