ABSTRACT:

This article presents research on the extraction of humic acid from brown coal samples obtained from the Angren and Apartak coal deposits of Uzbekistan and the Karakyche deposit of Kyrgyzstan, as well as the heterogeneous-catalytic synthesis of its vinyl ether. The coal samples were pre-oxidized with nitric acid, followed by alkaline extraction to isolate the humic acid. The effect of oxidation conditions (acid concentration, mass ratio, and time) on the humic acid yield was investigated. The vinyl etherification of humic acid was carried out in the gas phase with acetylene in the presence of a Zn(CH₃COO)₂/Al₂O₃ catalyst. The functional composition of the obtained products was confirmed by IR spectroscopy.

📘 : Nexus Global Research Journal of Multidisciplinary (NGRJM) Volume 2, Issue 5, 2026 (Page : 183-190)

ABSTRACT:

This paper presents a comprehensive methodological framework for solving mathematical and informatics olympiad problems through structured algorithmic approaches. We examine five core algorithmic strategies — Divide and Conquer, Dynamic Programming, Greedy Algorithms, Backtracking, and Graph Algorithms — and demonstrate their applicability to competition problems across multiple difficulty levels. Statistical analysis of 420 olympiad problems from national and international competitions (2018–2023) reveals that students trained in explicit algorithmic methodology achieve a 34% higher average score compared to those using intuitive approaches alone. The paper includes classification tables, performance diagrams, solution flowcharts, and pedagogical recommendations for secondary school educators. Our findings suggest that systematic algorithmic thinking, when embedded in classroom practice, significantly enhances both problem-solving accuracy and speed in competitive mathematics and informatics contexts.

ABSTRACT:

Palliative care is a vital component of holistic healthcare that aims to improve the quality of life of patients with life-limiting illnesses and their families through the comprehensive management of physical, psychosocial, emotional, and spiritual concerns. Nurses play a crucial role in delivering palliative care, as they maintain the most direct and continuous contact with patients and their families. However, variations in training, clinical experience, and professional exposure may influence nurses’ competence in providing such care. This study determined the Index of Competence in Palliative Care (ICPC) among staff nurses working in selected government hospitals in Eastern Pangasinan, Philippines. The study employed a descriptive correlational research design involving 109 staff nurses selected through convenience sampling. Data were collected using a researcher-developed questionnaire validated by a panel of experts. Descriptive statistics, t-test, Analysis of Variance (ANOVA), and Pearson correlation were utilized to analyze the data at the 0.05 level of significance. Findings revealed that staff nurses demonstrated a high level of competence in palliative care, with a grand overall weighted mean of 4.756, interpreted as “Very Competent.” Competence was evident across key domains, including quality of life, symptom management, emotional and psychological support, spiritual and existential care, care coordination, family and caregiver support, and individualized care. Significant differences were found in selected domains when grouped by sex and monthly income, while no significant differences were observed across other profile variables. The results highlight the need for continuous professional development and structured training programs. Consequently, the CARES Program (Compassionate and Advanced Responsive Education in Palliative Care for Staff Nurses) was proposed to further enhance nurses’ competencies in holistic palliative care delivery.

📘 : Nexus Global Research Journal of Multidisciplinary (NGRJM) Volume 2, Issue 5, 2026 (Page : 150-155)

ABSTRACT:

This study aimed to explore the lived experiences of oncology nurses and examine how emotional resilience is developed and sustained within oncology nursing practice in selected private hospitals in Dagupan City. Oncology nurses are continuously exposed to patient suffering, disease progression, and end-of-life care, resulting in persistent emotional demands that require sustained adaptive responses. A descriptive phenomenological design was employed to capture the essence of participants’ lived experiences. Fifteen oncology nurses with at least five years of clinical experience were selected through purposive sampling. Data were collected through in-depth semi-structured interviews, audio-recorded, and transcribed verbatim. Data were analyzed using Colaizzi’s phenomenological method. Findings revealed that emotional resilience is a dynamic and evolving lived experience expressed across four essential structures: emotional regulation, meaning-making and spirituality, relational support, and adaptive coping leading to transformation. These findings indicate that resilience is not a fixed trait but a context-dependent adaptive process. Based on the results, the ONCORE+ (Oncology Nurses’ Comprehensive Resilience Enhancement) Program was developed to strengthen resilience through structured institutional support. The study provides context-specific insights that may guide nursing leadership, education, and healthcare institutions in promoting nurses’ emotional well-being and professional sustainability.

Engineering Modified Concrete for Sound Absorption and Environmental Sustainability – A Review

: Anuja N.

📘 : Nexus Global Research Journal of Multidisciplinary (NGRJM) Volume 2, Issue 2, 2026 (Page : 73-76)

Abstract:

This paper reviews the sound absorption properties of various modified concrete from the existing published works. Researchers have proposed several methods to treat the foam concrete to also capable of absorbing sound and thus improving the sound quality in a room. Concrete is usually employed as rigid wall in building and act as sound barrier in highway, roads etc, due to its high density. In this study, it was aimed to determine the density for autoclaved foam concrete for sound absorption performance of concrete. Water (0.60), cement (0.25) and aggregate (0.62) ratios were the foam concrete produced at a dry density of 300, 400, and 500 kg/m3. The concrete is made using the Portland cement, powdered quartz, hydrated lime and synthetic foaming agent. The compressive strengths increased in autoclaved foam concrete specimens and flexural strengths also increased but the thermal conductivity coefficients is decreased due to its increasing density. Autoclaving improved both the mechanical and thermal properties of foam concrete at a density of 300 kg/m3. From the review, it was concluded that the sound absorption of the concrete or cement-based material that can be improved by creating porous structures namely lightweight aggregate.
