Abstract

General background: Polymer composites are widely developed to meet structural and functional demands through tailored fillers. Specific background: Epoxy matrices combined with particulate carbon black offer tunable mechanical strength and thermal transport. Knowledge gap: The coupled compressive response and heat conduction behavior across varied carbon black loadings, including recovery phenomena, remains insufficiently clarified. Aims: This study examines compressive strength and thermal conductivity of epoxy composites containing 0–9 wt% carbon black fabricated via hand lay-up. Results: Compressive strength peaked at 5 wt% carbon black, attributed to improved interfacial bonding and stress transfer, while higher contents reduced strength due to agglomeration. An unusual elastic-like recovery under compression occurred without catastrophic failure. Thermal conductivity increased monotonically, reaching a maximum at 9 wt% as conductive pathways developed. Novelty: The identification of pseudo-elastic recovery alongside opposing optima for mechanical strength and thermal transport provides a distinctive structure–property relationship. Implications: These findings guide composition selection for lightweight components requiring balanced load-bearing capacity and heat dissipation. Highlights Peak compressive strength achieved at 5 wt% carbon black. Elastic-like recovery observed under compressive loading. Thermal conductivity rises steadily with filler content. Keywords: Epoxy Composites; Carbon Black; Compressive Strength; Thermal Conductivity; Particle Reinforcement

Abstract

General Background: Education quality has shifted from output metrics toward institutional adaptability in producing relevant and competitive graduates amid global and technological disruption. Specific Background: Muhammadiyah private schools in Asahan Regency face dual demands to meet national standards while maintaining competitiveness with limited resources, especially across differing mandates of SMA and SMK. Knowledge Gap: Prior studies rarely provide comparative multi-case analysis distinguishing quality improvement strategies between general and vocational Muhammadiyah schools in specific regional contexts. Aims: This study aims to analyze and construct a strategic model of education quality improvement through a multi-case comparison of SMA and SMK Muhammadiyah in Asahan. Results: The findings reveal a Contextual-Differential Strategy Model based on two pillars: convergence in Al-Islam Kemuhammadiyahan values and teacher professionalism, and divergence in institutional focus, where SMA prioritizes academic pathways to higher education while SMK emphasizes industrial partnerships and work readiness. Novelty: The study introduces a pluralistic and goal-oriented perspective of education quality, rejecting uniform management approaches and emphasizing strategic differentiation within a shared organizational framework. Implications: The model provides a practical framework for policy formulation and school governance, promoting adaptive, context-based resource allocation and strengthening institutional identity to sustain competitiveness in regional education systems Highlights• Identifies dual strategic pillars combining shared values with operational differentiation• Demonstrates distinct institutional focus between academic and vocational pathways• Proposes adaptive governance framework based on contextual resource allocation KeywordsEducational Quality; Contextual Differential Strategy; Multi Case Study; Muhammadiyah Education; Asahan Regency

Abstract

General Background Local traditions represent accumulated cultural values that function as social frameworks within community life. Specific Background The Mangngade tradition in Mattampawalie Village, Bone Regency, persists as a hereditary cultural practice involving collective rituals, symbolic offerings, and communal participation rooted in local wisdom and acculturated religious values. Knowledge Gap Despite its continued practice, limited scholarly attention has explicitly positioned Mangngade as an active social mechanism that maintains social cohesion and collective identity amid modernization pressures. Aims This study aims to analyze the construction of the Mangngade tradition and examine its role in sustaining social cohesion and collective identity within the Mattampawalie Village community. Results Findings indicate that Mangngade functions beyond a spiritual ritual by internalizing core social values such as sipakatau, sipakalebbi, mutual cooperation, togetherness, and social responsibility through intensive intergenerational interaction and collective participation. These practices foster solidarity, trust, and harmonious social relations while reinforcing communal bonds. Novelty This research highlights Mangngade as a form of local wisdom that remains socially functional through adaptive practices, demonstrating its role as living social capital rather than a static ceremonial tradition. Implications The findings suggest that sustained synergy among customary leaders, village governance, and community members—particularly youth—supports the continuity of Mangngade as a cultural instrument that maintains social cohesion and collective identity in the context of ongoing social change. Highlights: Communal rituals internalize shared values that maintain solidarity and togetherness. Collective participation creates sustained intergenerational social interaction. Adaptive cultural practices preserve communal bonds amid social change. Keywords : Mangngade Tradition, Social Cohesion, Collective Identity, Local Wisdom, Community Participation

Abstract

General Background: Intestinal protozoal infections constitute a substantial public health burden in developing countries, contributing to considerable gastrointestinal morbidity among pediatric populations. Specific Background: Entamoeba histolytica and Giardia lamblia infections have been associated with malabsorption and subsequent micronutrient deficiencies in children. Knowledge Gap: Despite documented individual nutrient deficiencies, the concurrent effects of these protozoal infections on vitamin D, calcium, and vitamin C status remain inadequately characterized in Middle Eastern pediatric populations. Aims: This case-control study evaluated serum concentrations of vitamin D, calcium, and vitamin C among male children aged 1-10 years infected with E. histolytica, G. lamblia, and healthy controls in Thi-Qar Governorate, Iraq. Results: Infected children demonstrated significantly reduced micronutrient levels compared to controls (P < 0.001), with G. lamblia infection exhibiting the most pronounced deficiencies. Large effect sizes were observed for vitamin D (η² = 0.41), calcium (η² = 0.36), and vitamin C (η² = 0.52). Novelty: This investigation represents the first comprehensive assessment of multi-micronutrient deficiency patterns associated with these protozoal infections in Iraqi children. Implications: These findings underscore the necessity for integrated parasitological-nutritional interventions in clinical management protocols to optimize therapeutic outcomes and prevent long-term developmental consequences.Highlight : Children infected with Giardia lamblia showed the lowest serum vitamin D and calcium levels, indicating more severe malabsorption than Entamoeba histolytica infection. Intestinal protozoal infections were associated with concurrent deficiencies of vitamin D, calcium, and vitamin C, reflecting a multi-micronutrient depletion pattern rather than isolated deficits. Large effect sizes confirmed a strong association between protozoal diarrhea, reduced body mass index, and disturbed micronutrient homeostasis in affected children.

Abstract

General Background: Preeclampsia is a leading cause of maternal and perinatal morbidity and mortality worldwide, with early prediction remaining a critical challenge in obstetric care. Specific Background: Conventional diagnostic approaches based on clinical and isolated biochemical markers often identify the disorder at advanced stages and fail to capture its multifactorial pathophysiology. Knowledge Gap: There is limited integration of multidimensional clinical, biochemical, and Doppler data into robust predictive models capable of early and individualized risk assessment. Aims: This study aimed to develop and evaluate a machine learning–based model for early prediction of preeclampsia using comprehensive antenatal data. Results: In a retrospective cohort of 1,200 pregnant women, the Extreme Gradient Boosting (XGBoost) model demonstrated superior performance, achieving an AUC of 0.94, sensitivity of 91%, specificity of 89%, and overall accuracy of 90%, outperforming random forest, support vector machine, and logistic regression models. Key predictors included mean arterial pressure, maternal age, uterine artery pulsatility index, placental growth factor, and soluble fms-like tyrosine kinase-1. Novelty: The study integrates 35 heterogeneous parameters into an AI-driven framework, highlighting the strength of ensemble learning in capturing nonlinear risk patterns. Implications: AI-based predictive tools offer significant potential for early identification of high-risk pregnancies, enabling targeted preventive interventions and advancing precision obstetrics to reduce preeclampsia-related adverse outcomes.Highlight : XGBoost showed high accuracy for early preeclampsia risk prediction. Combined clinical, biochemical, and Doppler data enabled early risk identification. Early prediction supports timely preventive obstetric interventions.

Abstract

General Background: Acute appendicitis represents the most prevalent acute abdominal pathology requiring surgical intervention. Specific Background: Appendicular infiltrate, occurring in 1-10% of acute appendicitis cases, poses diagnostic challenges that frequently result in inappropriate treatment selection and unjustified surgical procedures. Knowledge Gap: Despite its clinical significance, standardized diagnostic criteria and management protocols for appendicular infiltrate remain inadequately defined, particularly regarding intraoperative recognition and intervention decisions. Aims: This study analyzed diagnostic approaches and treatment outcomes in patients presenting with appendicular infiltrate to establish evidence-based management protocols. Results: Among 3,567 patients treated for acute appendicitis between 2020-2024, appendicular infiltrate was identified in 38 cases (1.1%). Delayed presentation constituted the primary etiological factor (75%), while atypical appendiceal positioning complicated diagnosis in 7.9% of cases. Conservative management achieved successful resolution in 78.9% of patients, whereas 21.1% required surgical intervention due to abscess formation. Intraoperative identification of infiltrate in six patients necessitated procedure termination with drainage placement; one attempted appendectomy resulted in postoperative complications. Novelty: This investigation establishes that immediate cessation of surgery upon intraoperative infiltrate recognition minimizes complications. Implications: These findings emphasize prioritizing conservative management and avoiding appendectomy when infiltrate is encountered operatively.Highlight : Late patient presentation is the primary factor in the development of appendicular infiltrate. Diagnostic difficulties, including atypical appendix location, often lead to tactical errors. Conservative management is effective in most cases, while unjustified appendectomy increases postoperative complications.

Abstract

General Background: Accurate assessment of liver functional reserve remains critical in surgical practice, as hepatic dysfunction substantially elevates postoperative morbidity and mortality risks. Specific Background: Conventional biochemical markers (ALT, AST, bilirubin) predominantly reflect cytolysis and cholestasis but fail to evaluate hepatocellular energetic status or regenerative capacity. Knowledge Gap: Current diagnostic approaches lack objective quantitative indicators that directly measure mitochondrial function and viable hepatocyte populations in surgical patients. Aims: This study evaluated a novel prognostic coefficient based on the ratio of cytochrome C to TMPD oxidase mitochondrial activities for quantifying liver parenchymal preservation in patients with hepatobiliary surgical diseases. Results: Analysis of 24 patients demonstrated strong inverse correlation between coefficient values and viable hepatocyte percentages. Coefficients of 2.5-3.5 units indicated favorable prognosis, 5-7 units signaled elevated complication risk, while values ≥8 units predicted unfavorable outcomes, irrespective of standard biochemical parameters. Novelty: Unlike traditional markers, this coefficient directly reflects mitochondrial respiratory chain integrity and hepatocellular viability through objective biochemical measurements. Implications: The proposed coefficient serves as an integrated quantitative marker of hepatic functional reserve, enabling improved surgical risk stratification and outcome prediction in hepatobiliary surgery.Highlight : The cytochrome C to TMPD oxidase ratio correlates better with hepatocyte viability than standard biochemical markers in both experimental and clinical contexts. Coefficient values predict postoperative outcomes: 2.5-3.5 units indicate favorable prognosis, 5-7 units suggest complications, and ≥8 units correlate with mortality. Mitochondrial dysfunction demonstrates universal quantifiable patterns across different etiologies, showing consistent relationships between the coefficient and hepatocyte viability. Keywords :Liver Functional Reserve, Mitochondrial Dysfunction, Cytochrome C Oxidase, Hepatocyte Viability, Postoperative Prognosis
