| 61 | 2026 Article | Synergistic effects of radiotherapy and Capsaicin on Colorectal Cancer (CaCo-2) and Normal Fibroblast (HDFn) cell lines in vitro Hatif, Abbas R. Colorectal cancer is the second most frequent kind of cancer worldwide. The treatment may comprise surgery, chemotherapy, and radiation therapy. More than half of cancer treatments are derived from natural sources, such as capsaicin. The biggest challenge is to get the disease under control as much as possible while causing as little harm to the healthy tissues around it. Cells were treated with an extract, Capsaicin of (chili peppers) and irradiated at 1 Gy, 3 Gy and 5 Gy. The MTT test was used to determine viability, and absorbance was measured at 570 nm using a Counter reader (Mutiskan EX, Thermo Lab systems). Capsaicin extract has shown a potential radiosensitizing effect in vitro for colorectal cancer. The inhibition effect in the cell lines was not selective and is significantly different from conventional radiotherapy. Capsaicin extract from chili peppers concerted with radiation proved more effective in colorectal cancer cells than radiotherapy alone.

| 62 | 2026 Article | Rat dissection alternatives in Biology education: a systematic literature review Teoh, Chern Zhong Despite the importance of both rat dissection and alternatives for rat dissection, proponents for these alternatives became more apparent during the COVID-19 pandemic and post-pandemically. Incorporating humane education into the Malaysian education system, whereby 3R (reduction, replacement, or refinement) is urged, aligns with the United Nations Sustainable Development Goals (SDGs). Utilising technology is an essential component of any 21st-century learning. Therefore, this study was carried out to explore the need for alternatives in rat dissection that provide both a high learning experience and feasibility using the Systematic Literature Review (SLR). Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) technique is employed. Examining selected literature revealed a substantial positive effect on the student's learning experience regarding perception, task performance, exam performance, and motivation. It is found to be either superior or equivalent to the i..... 47 hits |

| 64 | 2026 Thesis | Investigation of Essential oil, phytochemicals and antibacterial activity of piper frustratum boerl Syarifah Nadhirah Wan Idrus The aim of this study was to investigate the essential oil composition, phytochemicals, and antibacterial activity of Piper frustratum, Piperaceae. Essential oil was obtained from the leaves of P. frustratum via hydrodistillation and its chemical composition was determined using gas chromatography (GC) and gas chromatography mass spectrometry (GC-MS). Cold extraction was performed to obtain the leaf extract, followed by isolation of phytochemicals using column chromatography techniques, and structural elucidation was achieved via various spectroscopic methods in comparison with literature. Antibacterial activity was evaluated using micro-dilution method. Results showed that nineteen chemical constituents were identified in the essential oil of P. frustratum leaf, accounting for 99.6% of the total composition. The major constituents include _-caryophyllene (12.6%), _-asarone (10.7%), myristicin (10.4%), _-copaene (9.6%), methyl eugenol (7.2 %), and _-cubebene (6.5%). Isolation and purif..... 60 hits |
| 65 | 2026 Article | Effect of mind-mapping instructional strategy on students achievement in Mathematics in Ogun State Nigeria Abiodun, T.O Several studies have shown that using mind mapping as an approach to teaching Mathematics has a more positive impact on student achievement than traditional approaches. However, these studies did not address the effect of mind mapping in other countries, such as Nigeria, at a secondary school level; they focused more on digital mind_mapping for pre-service teachers. This study examined how students' mathematics achievement in Ogun State, Nigeria, was affected by the mind mapping instructional technique. Nonrandomized pre-test post-test control group design, or quasi-experimental non-equivalent group research design, was used. A simple random sample technique was used to assign one school to the experimental group and another school to the control group. The data required for the study was collected using the Mathematics Achievement Test, which has a reliability coefficient of 0.87 according to the Kuder-Richardson formula 20 (KR20). Four hypotheses were tested at the 0.05 significant l..... 55 hits |
| 66 | 2026 Article | Computational analysis of fractional systems of korteweg-de vries equations using Elzaki Projected Differential Transform Method Gbodogbe, Sunday Oluwafemi This study investigates the application of the Elzaki Projected Differential Transform Method (EPDTM) to fractional-order nonlinear Korteweg-de Vries (KdV) equations, which describe various nonlinear wave phenomena in physics and engineering. The method effectively addresses both linear and nonlinear operators and fractional derivatives. Through two illustrative examples, the method accurately captures the dynamics of fractional-order wave systems and achieves results in excellent agreement with exact solutions. The findings demonstrate the method_s precision, fast convergence, and computational efficiency, underscoring EPDTM's potential as a robust tool for solving nonlinear partial differential equations with fractional dynamics.

| 67 | 2026 Article | Comparative analysis of particle grain size distribution and moisture content in beach and paddy field sediments Nur Azlin Atikah Mohd Nasir This study aims to compare particle grain size and moisture content in samples from beach sediment and paddy fields. Grain size variations were measured along different zones and stations in a line transect at each location. The grain sizes for both study areas were determined using drysieving and a Laser Diffraction Particle Size Analyzer. Results showed that beach sediment mostly consists of medium sand, is moderately sorted, very negatively skewed, and extremely leptokurtic. In contrast, paddy field sediment is mostly very fine silt, very poorly sorted, negatively skewed, and very leptokurtic. The mean of particle grain size recorded in beach and paddy field were 1.57 _ 0.23 and 7.63 _ 0.44 respectively. Moisture content was measured using oven-drying method. The mean of moisture content recorded in beach and paddy field were 6.72 _ 5.01% and 52.03 _ 3.35% respectively. Results revealed that paddy fields have significantly higher moisture content than beach sediment. Descriptive ana..... 62 hits |
| 68 | 2025 Thesis | Gamification as a mediator of teacher related factors and teaching effectiveness in science primary education Pingalan Gejandran This study aimed to develop a model explaining the mediating role of gamification in teaching effectiveness within the primary science education context. Data were collected from 686 primary school teachers in Perak using validated questionnaires on Technological Pedagogical Content Knowledge (TPACK), Teacher Behaviour, Teacher Self-Efficacy, Psychological Characteristics, Gamification, and Teaching Effectiveness. Measurement model analysis confirmed satisfactory reliability and validity (CR = 0.892_0.991; AVE = 0.623_0.868). Partial Least Squares Structural Equation Modeling (PLS-SEM) was conducted using SmartPLS 4.The results showed that Teacher Behaviour (_ = 0.063, p < 0.001), Self-Efficacy (_ = 0.159, p = 0.001), Psychological Characteristics (_ = 0.149, p = 0.001), and Gamification (_ = 0.143, p = 0.004) significantly influenced Teaching Effectiveness, while TPACK was not significant (_ = 0.063, p = 0.135). Mediation analysis revealed that Gamification significantly mediated the ..... 47 hits |
