Research ArticleOpen accessIn the keywordsKinematics of a Mechanism with a TriadRelly Victoria Virgil Petrescu, Raffaella Aversa, Taher M. Abu-Lebdeh et al.The Assuric Structural Groups are the most well-known classification and modulation used in machine and machine theory, and even though other modular classifications adapted to robots have emerged today, they still remain a reference classification in industrial mechanics and engineering. Diada in the mechanics can be studied similarly to the diode in the electronics, the triad is studied in the … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 2 Mar 2018 · 7,340 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 abstractAn Adaptive Detail Preserving Modified Progressive Pca Thresholding Based Image DenoisingN. Anilkumar, S. Radhakrishnan, Shaik Syed Basha et al.Radiologists use medical imaging tools to assess the anatomy and function of interior organs. However, medical images are frequently distorted by various types of noise generated during the capture, transmission, and reconstruction operations, which can dramatically reduce image quality and hide critical diagnostic features. As a result, developing effective denoising algorithms that suppress noise while maintaining structural information remains a … …Journal of Computer Science, Vol. 22, Issue 8 · 8 Sep 2026 · 529 accessesView PDFCite
Research ArticleOpen accessIn the abstractFrom Digital Engagement to Social Welfare: Measuring the Impact of the mSmart Application in a Developing RegionHendro Nindito, Evaristus Didik Madyatmadja, Siti Elda Hierra, MaryaniThe mSmart platform, introduced as a pilot initiative in Labuan Bajo, Indonesia, was developed to strengthen community participation in local digital services. This study explores the extent to which the application delivers social value to its users and the broader community. Guided by the Information Systems Success Model (ISSM) and the WebQual framework, the research focuses on three main factors: … …Journal of Computer Science, Vol. 22, Issue 5 · 25 May 2026 · 1,228 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 abstractAssessing Behavioral Intention to Adopt Online Tax Return in BangladeshMustafa Manir Chowdhury, Kulsuma Aktar, Mohammad Toufiqur Rahman et al.Tax e-filing, which allows individuals to submit their taxes electronically to the government, is a key e-government service increasingly adopted in developed countries. Bangladesh, a developing nation, has recently introduced online tax filing. This study aims to explore the factors influencing the adoption of online tax returns, focusing on awareness, accessibility, benefits, costs, and their impact on the future of … …Journal of Computer Science, Vol. 21, Issue 2 · 31 Dec 2024 · 5,104 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermodynamic Inference of the Antioxidant Process of Malic Acid and Its Structural AnalogsHan Wu, Wenhao Dong et al.Two structural analogs of Malic Acid (MA), 2-isopropylmalic Acid (2-IPMA), and 3-isopropylmalic Acid (3-IPMA) were recently identified and separated from wine. Although they have been shown to have antioxidant activity, the mechanism of their actions is still unclear. Antioxidant activities of 2-IPMA and MA were tested through DPPH, ABTS, and PTIO methods and the antioxidant-related thermodynamic properties were evaluated using … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 4 · 30 Oct 2024 · 4,824 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessing the Toxic Effects of Topik80ec on Rabbit Testicular Morphometry and HistologySamia Rebahi, Alouani Abdelouahab, Meguini Mohamed Nadir et al.This study aimed to investigate the toxic impact of Topik80ec on rabbit testes through morphometric and histological analyses. Twenty-four adult male domestic rabbits (Oryctolagus cuniculus) were used, where three experimental groups, G1, G2, and G3, were assigned and provided escalating dosages of Topik80 EC for a duration of four weeks, while one group served as the control group and received … …OnLine Journal of Biological Sciences, Vol. 25, Issue 1 · 14 Sep 2024 · 5,015 accessesView PDFCite
Research ArticleOpen accessIn the abstractUltrastructural Morphology of the Muscle System Organization in the Trematode Typhlocoelium cucumerinumIrina Yurievna Chidunchi, Ainagul Balgauovna Kaliyeva, Natalya Petrovna Korogod et al.Trematodes, also known as flatworms, are a diverse group of parasitic organisms that live in a variety of ecosystems, from freshwater to marine habitats. Their complex life cycle often involves intermediate and definitive hosts and multiple developmental stages. Trematodes have unique morphological features that allow them to adapt, move and parasitize within host tissues and organs. The parasitic lifestyle of … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 1 Jun 2024 · 5,112 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Acute Oral Toxicity Induced by Tablets Based on Ethanolic Extract of Salvia dumetorum Leaves in Experimental RatsYana Levaya, Karakoz Badekova, Mussa Zholdasbayev, Gayane AtazhanovaThe aim of this study was to assess the acute oral toxicity of a solid dosage form based on Salvia dumetorum Andrz. ex Besser leaf extract (SDT5) in experimental rats.
