“…The statistical technique known as the coefficient of determination (R 2 ) can be used to evaluate the accuracy and dependability of a predictive model [58,59]. The R 2 coefficient serves as a measure of the extent to which the model that has been fitted conforms to the data that has been observed [67,68]. The metric evaluates the degree of congruence between the model and the data [69].…”

Concrete is a widely utilized construction material globally; however, it is characterized by a fundamental deficiency in its tensile strength when it is not reinforced. The incorporation of diverse novel materials into concrete is being pursued with the aim of mitigating its limitations while concurrently enhancing its reliability and sustainability. Furthermore, it is noteworthy that concrete embodies a significant quantity of carbon. The primary cause of this phenomenon can be attributed to the utilization of cement as the principal binding component in concrete. Recent advancements in research have indicated that jute fiber, commonly referred to as JF, exhibits considerable potential as a novel material for enhancing the mechanical robustness of concrete. Although there is a significant body of literature on the application of jute fiber in concrete, there has been a dearth of research on the capacity of jute fiber (JF) to improve the mechanical strength of concrete and mitigate its carbon emissions. This study aims to cover a gap in the existing literature by analyzing and enhancing the application of JF in relation to its mechanical properties and environmental impact. The study involved conducting experiments wherein JF was added at varying weight percentages, specifically at 0%, 0.10%, 0.25%, 0.50%, and 0.75%. The investigation encompassed a number of examinations of both the fresh and hardened states of concrete, in addition to assessments of its durability. The fresh concrete tests included the slump test, while the hardened concrete tests involved measuring compressive strength (CS), split tensile strength (STS), and flexural strength (FS). Additionally, the durability tests focused on water absorption (WA). The study involved the computation of embodied carbon (EC) ratios for various mix combinations. The findings suggest that incorporating JF into concrete results in a decrease in environmental impact relative to alternative fiber types, as demonstrated by a rise in eco-strength efficiency (ESE). Based on the findings of the conducted tests, an optimal proportion of 0.10% JF has been determined to be conducive to enhancing the CS, STS, and FS by 6.77%, 6.91%, and 9.63%, respectively. The aforementioned deduction can be inferred from the results of the examinations. Using data obtained from extensive experimentation, the RSM (Response Surface Methodology) was used to construct a model. The model was optimized, resulting in the establishment of definitive equations that can be used to evaluate the effects of incorporating JF into concrete. Potential benefits have been identified for the advancement of concrete in the future through the utilization of JF.

Purpose The study explores the impact of Musculoskeletal Injuries on the quality of life in youth athletes, aiming to understand the extent of these injuries’ effects on their physical and mental wellbeing. Patients and Methods This cross-sectional study included 130 youth athletes, using questionnaires to collect data on demographics, training exposures (averaging 11±3.8 hours/week), overuse symptoms (using the Oslo Sports Trauma Research Center Overuse Injury Questionnaire), acute injury history, and overall wellbeing (assessed by the RAND 36-item Short Form Health Survey). Results Findings indicated that 55.4% of participants had suffered an acute injury in the past 6 months, leading to an average of 4 weeks of time loss. The mean score for OSTRC-O Scores was 16.8±6.4, with knee overuse averaging 21.3± 8.8. In terms of wellbeing, physical and mental health scores were 82.4±15.3 and 81.7±14.1 respectively. There were significant correlations between higher overuse scores and poorer physical functioning (r=−0.42), bodily pain (r=−0.38), vitality (r=−0.32), and mental health (r=−0.31). Acute injuries were linked with worse physical functioning and role limitations. Regression analysis showed that both overuse and acute injuries predicted poorer physical health. Conclusion The study underscores the significant prevalence of musculoskeletal injuries among youth athletes and delineates their profound impact on the quality of life, encompassing both the physical and mental health realms. These findings advocate for the critical integration of preventive measures and personalized training protocols, spotlighting the pivotal role of comprehensive biopsychosocial strategies in nurturing athletes’ overall wellbeing. By prioritizing the quality of life as a key outcome, this research advocates for a more nuanced approach to injury management and recovery.

Operators of offshore production units (OPUs) employ risk-based assessment (RBA) techniques in order to minimise inspection expenses while maintaining risks at an acceptable level. However, when human divers and workers are involved in inspections conducted at high heights, the operational risks can be significant. Recently, there has been a growing trend towards the use of unmanned aerial vehicles (UAVs), autonomous surface vehicles (ASVs), remotely operated vehicles (ROVs), and autonomous underwater vehicles (AUVs) for inspections of offshore structures as a means to reduce exposure to human risk. This article provides an analysis of these vehicle inspection capabilities and their potential to enhance robustness and safety within the oil and gas industry. The review assesses both the advantages and the drawbacks associated with these innovative systems, providing valuable comparisons and assessments on their potential use as viable alternatives to conventional inspection methods.
