Research ArticleOpen accessIn the keywordsStatic and Dynamic Performance Improvement of Conventional Computer Numerical Control Machine Tool Bed with Hybrid Welded SteelS.S. Abuthakeer, P.V. Mohanram, G. MohankumarProblem statement: The advancements in machine tools to maximize the production by increasing spindle speeds have caused vibration in machine tools. The two functional requirements of machine tool bed for machine tools are high structural stiffness and high damping, which cannot be satisfied simultaneously if conventional metallic materials such as cast iron are employed. Hence there is a need to … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 11,479 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Water Bath Heating on Tannin Content and Quality Improvement Potential of Gambier (Uncaria gambir Roxb.)Daimon Syukri, Bastian Nova, Rina Yenrina et al.Gambir (Uncaria gambir Roxb.) is a source of natural phenolic compounds rich in catechins and tannins and has potential as a sustainable industrial raw material. During heating, phenolic compounds may undergo structural changes, including possible oxidation and polymerization, which can affect gambier quality beyond its catechin content. This study evaluated the effect of indirect heating duration using a water bath … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 23 Sep 2026 · 704 accessesView PDFCite
Research ArticleOpen accessIn the abstractMolecular Identification and Antioxidant Profiling of Penicillium heteringtonii EUA-017 from Mangrove (Avicennia alba) in West Sumatra, IndonesiaAnthoni Agustien, Djong Hon Tjong, Yetria Rilda et al.Mangrove ecosystems harbor diverse endophytic fungi that produce bioactive secondary metabolites with potential antioxidant activities. This study aimed to identify an endophytic fungal isolate (EUA-017) from Avicennia alba mangroves in West Sumatra, Indonesia, and characterize its antioxidant metabolites. Molecular identification was performed using internal transcribed spacer (ITS) region sequencing. Secondary metabolites from ethyl acetate extracts were characterized using Fourier-transform infrared … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 25 Mar 2026 · 1,410 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Systematic Review of Metaheuristic-Metaheuristic (MH-MH) Hybridizations for OptimizationAugustina Dede Agor, Frank Kataka Banaseka, Prince Silas Kwesi Oberko et al.This systematic review following the PRISMA framework analyzes metaheuristic-metaheuristic (MH-MH) hybridizations published between January and October 2024 to uncover patterns of algorithmic dominance, functional roles and integration strategies, metaphor-based partnerships, domain mappings and evaluation orientations. Frequency mapping of 105 canonical algorithms identified Particle Swarm Optimization (PSO), Grey Wolf Optimizer (GWO), and Whale Optimization Algorithm (WOA) as the three most recurrent … …Journal of Computer Science, Vol. 22, Issue 2 · 4 Mar 2026 · 2,183 accessesView PDFCite
Research ArticleOpen accessIn the abstractCloning and Expression of SCAMP3 in Transgenic Silkworm (Bombyx mori)Selly S. Rajagukguk, Sabar Pambudi, Astari Dwiranti et al.SCAMP3 (Secretory Carrier Membrane Protein 3) is a crucial component of vesicular trafficking pathways and plays important roles in endocytosis and protein recycling. Previous studies demonstrate SCAMP3 dysregulation in various cancers, suggesting potential applications as a biomarker and therapeutic target. Understanding SCAMP3 expression and post-translational processing provides insights into its biological functions and potential applications in cancer diagnostics and therapy. … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 16 Feb 2026 · 1,521 accessesView PDFCite
Research ArticleOpen accessIn the abstractPurification, Structural Characterization and Anti-Aging and Stress Activities of Cordyceps Mycelium Polysaccharides from Paecilomyces HepialiXiaokang Hu, Huixiu Ma, Guicai Chen et al.This study identified and characterized the bioactive polysaccharide components from Cordyceps mycelium powder (CMP) derived from Paecilomyces hepiali, evaluating their anti-aging and stress-protective activities. Initial screening using Drosophila melanogaster revealed that crude Cordyceps polysaccharides (CCP) exhibited comparable effects to CMP and Cordyceps aqueous extracts (CAE) on natural lifespan and UV stress resistance, suggesting CCP as the primary bioactive component. CCP … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 16 Feb 2026 · 1,698 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Analysis of Proteins in Two Typical Chinese Thin-Shell WalnutsXu Meng, Tian YilingThis study compared functional properties and molecular characteristics of proteins from two thin-shelled walnut (Juglans regia L.) cultivars predominantly grown in China: Wen 185 and Lvling. Wen 185 walnut protein demonstrated significantly superior performance compared to Lvling across multiple functional parameters, including solubility, emulsifying capacity, foaming capacity, water absorption, and oil absorption. Molecular weight distribution analysis revealed that both proteins … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 4 · 15 Feb 2026 · 1,481 accessesView PDFCite
