Research ArticleOpen accessIn the abstractCharacterization of Pseudomonas aeruginosa Infecting Bacteriophages from Swiftlet House Pond Water and Sewage in South Kalimantan, IndonesiaSiti Gusti Ningrum, Dyah Widhowati, Titin Yulinery et al.Pseudomonas aeruginosa is an opportunistic bacterium that may occur in animal-production environments and contribute to microbial contamination of animal-derived products. However, information on P. aeruginosa-infecting bacteriophages in artificial swiftlet-house environments remains limited. This study aimed to isolate and evaluate P. aeruginosa-infecting bacteriophages from the swiftlet-house environment in South Kalimantan, Indonesia. A total of 75 samples involving pond waters (n = … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 3 · 26 Oct 2026 · 55 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 abstractA Context-Aware Temporal Convolutional Network for Water Replacement Prediction in Catfish Biofloc Ponds With Imbalanced Event HandlingYaddarabullah, Inanpi Hidayati Sumiasih, Mutiara Dewi PuspitawatiWater replacement is a biologically critical yet under-automated decision in biofloc-based aquaculture systems. Mistimed actions can destabilize microbial ecosystems, elevate fish mortality, and compromise sustainability through excessive water usage. Traditional rule-based heuristics often fail to account for the nonlinear and multiscale dynamics of pond environments. To address this, we propose a Context-Aware Temporal Convolutional Network (CA-TCN), a rare-event classification framework … …Journal of Computer Science, Vol. 22, Issue 3 · 5 Mar 2026 · 1,664 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Ozonated Water on the Bond Strength of FL Bond II Adhesive to EnamelFernanda Rafaela Ribeiro, Caterine Renata Passaglia, Julio Katuhide Ueda et al.The aim of this study was to investigate the potential of ozonated water as an oxidative cleaning solution to improve the bond strength of a bioactive adhesive system to enamel without prior etching. Forty bovine anterior tooth crowns were used and divided into four groups according to the cleaning solution and storage time: AD24 h (cleaning with distilled water, 24 … …Current Research in Dentistry, Vol. 16, Issue 1 · 7 Jul 2025 · 5,787 accessesView PDFCite
Research ArticleOpen accessIn the abstractBond Strength of Bioactive vs. Conventional Resin Composites on Dentin Cleaned with Ozonated Water: An In Vitro StudyFernanda Rafaela Ribeiro, Anna Caroliny Detogni, Julio Katuhide Ueda et al.This study aimed to compare the micro tensile bond strength (μTBS) of bioactive and conventional resin composite to human dentin after the use of ozonated water (AO) as a cavity cleaning solution. A total of 32healthy human third molars were randomly assigned to four groups (n = 8)based on the type of composite and dentin cleaning. The first group received … …Current Research in Dentistry, Vol. 16, Issue 1 · 9 Jun 2025 · 6,312 accessesView PDFCite
Research ArticleOpen accessIn the abstractImportance of Soil and Mineral Characteristics in Supporting Sustainable AgricultureIda Suryani, Marliana Sjuaib Palad, Nur Fitriani et al.Soil consists of four main components: Minerals, organic matter, air, and water, which are arranged in the space to form the soil body. Inorganic minerals in the soil come from rock fragments and other primary minerals. Sustainable soil fertility is supported by the nutrient content contained in the minerals. The research objectives were: 1) to observe the physical and chemical … …OnLine Journal of Biological Sciences, Vol. 25, Issue 2 · 25 Mar 2025 · 5,938 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiosynthesis and Evaluation of Zinc, Copper, and Methionine Feed Supplements Using Saccharomyces cerevisiae on Duck Performance in Minimal Water SystemsHendi Setiyatwan, Muhammad Rifqi IsmirajOptimizing duck performance under minimal water conditions is essential for sustainable poultry farming. Biosynthesizing essential feed supplements like Zinc (Zn), Copper (Cu), and methionine using Saccharomyces cerevisiae presents a promising method to enhance growth and meat quality. This study developed a biosynthesis method for Zn, Cu, and methionine supplements using S. cerevisiae and evaluated their effects on duck performance.
