Research ArticleOpen accessIn the abstractSafe Ulvan Silver Nanoparticles Composite Films for Active Food PackagingHadear Hanie AminProtecting food from the corruption caused by different microbes is a big problem, as we need safe methods for food packaging. In this study, Ulvan (U), edible sulfated polysaccharide extracted from Ulva lactuca, was mediated for the first time non-toxic biosynthesized silver nanoparticles (Ag-NPs) to produce new and safe bio-nanocomposite films called (U/Ag-NPs) films for active food packaging. Ulvan was … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 1 · 28 Jan 2021 · 7,748 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancing Kidney Stone Detection Accuracy Using Image Processing and a Hybrid Convolutional Deep Belief NetworkGeetha M. N, Barkathulla A, S. Nandhini Devi et al.Automated CKD is a rapidly expanding non-communicable ailment that significantly contributes to global mortality and morbidity. CKD impacts more than 10% of the worldwide population, leading to millions of deaths annually. This paper proposes an enhanced deep learning model for renal disease detection that integrates convolutional and involution layers to enhance classification accuracy. CKD is a worldwide health issue characterised … …Journal of Computer Science, Vol. 22, Issue 10 · 9 Oct 2026 · 774 accessesView PDFCite
Research ArticleOpen accessIn the abstractSustainable Technology for Agriculture at Extreme Altitudes: Design and Evaluation of a Sprinkler Irrigation System in a Peruvian High Andean CommunityJuan Eduardo Suarez Rivadeneira, Freddy A. Manayay, Daniel Olivier Carranza Lizana et al.In high-altitude agroecosystems, erratic rainfall patterns and steep topography severely constrain crop productivity by exposing plants to soil water deficits during critical phenological stages. This study aimed to enhance the productivity of eleven staple and horticultural crops corn (Zea mays), tomato (Solanum lycopersicum), cucumber (Cucumis sativus), eggplant (Solanum melongena), lettuce (Lactuca sativa), carrot (Daucus carota), barley (Hordeum vulgare), celery (Apium … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 2 Oct 2026 · 663 accessesView PDFCite
Research ArticleOpen accessIn the abstractMRI Observation and Analysis of Muscle Activity During ExerciseLi-Chang Zou, Hong-Wu LiWhile conventional biomechanical testing techniques are able to determine the mechanical characteristics of muscle tissue, they do not offer precise insight into how muscle metabolism and microstructure change in response to various types of exercise activities over the course of time. Using Magnetic Resonance Imaging (MRI) analysis of muscle tissue allows researchers to examine how different levels of intensity affect … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 30 Jul 2026 · 1,035 accessesView PDFCite
Review ArticleOpen accessIn the abstractLeveraging Artificial Intelligence and Other 4IR Technologies for Driving Education 4.0 in South Africa: A Scoping StudyEmmanuel Adetiba et al.The advent of the fourth Industrial Revolution (4IR) has impacted human life across many disciplines including healthcare, agriculture, telecommunication, manufacturing, education etc. It is characterized by cyber physical systems thus enabling automation of processes, in which devices can autonomously communicate. Some of the technologies that drive 4IR include Artificial Intelligence (AI), Internet of Things (IoT), big data, drone technology, robotics … …Journal of Computer Science, Vol. 22, Issue 7 · 9 Jul 2026 · 1,685 accessesView PDFCite
Research ArticleOpen accessIn the abstractTesticular Development in Holstein, F1 Crossbred Holstein-Gyr, Gyr, and Nellore Bulls During Puberty and Sexual Maturity in Tropical ConditionsGustavo Eduardo Freneau, Jose Domingos Guimaraes, Vicente Ribeiro Vale Filho, Arnhold EmmanuelContext: Puberty and sexual maturity are very important economic aspects in the beef industry and bull production. The aim of this study was to characterize and determine the sexual development of Bos taurus, Bos indicus, and F1 crossbreeds of these two subspecies of bulls and their testicular growth and shape. We observed the evolution of testicular development characteristics and seminal … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 2 · 9 Jul 2026 · 1,204 accessesView PDFCite
Research ArticleOpen accessIn the abstractOff-road Vehicle-Induced Substrate Vibrations Are Associated with Strong Declines in Ectomycorrhizal Mushroom Fruiting in Forest EcosystemsLev ShestakovWe conducted a multi-year (2020-2024) control-impact field study in a pine forest of the Moscow Region to assess whether off-road vehicle activity affects the fruiting of two ecologically important ectomycorrhizal fungi, Boletus edulis and Suillus luteus. Substrate vibrations associated with vehicle passage were recorded and characterized by dominant energy in the low-frequency range. Over the study period, abundance in disturbed … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 23 May 2026 · 1,309 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimizing KNN for Face Recognition and Location Detection in Mobile Employee Attendance Systems Using Machine LearningPainem, Hari Soetanto, Achmad Solichin, Ibnu RamadhanEmployee attendance is critical to company operations, particularly for firms involved in ATM installations collaborating with banks. An effective attendance system enables bank vendors to verify the completion of ATM installations. The current attendance method employed by the company requires employees to send photos of themselves with the installed ATM, including the machine number and installation location. The company's admin … …Journal of Computer Science, Vol. 21, Issue 5 · 14 Apr 2025 · 5,996 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel River Meander Migration and Cutoff Model: A New PerspectiveYoussef Ismail HafezAccurate prediction of river meander migration is crucial for effective river management and operation, particularly in light of climate changes and human-induced interventions. Existing models often rely on single-equation approaches, such as bank erosion rate versus excess bank velocity or excess bank shear stress, which limit their ability to comprehensively capture the complex dynamics of meander evolution. This study presents … …American Journal of Environmental Sciences, Vol. 21, Issue 1 · 21 Mar 2025 · 7,687 accessesView PDFCite
Research ArticleOpen accessIn the abstractTopological Approach for Mechatronic SystemsDamasse Harold Tchouazong, Jean Bosco SamonIn this study, we propose a topological methodology for mechatronic systems which is much more focused on the mechanical part of the mechatronic system based on the work of Casner. The methodology starts with the optimization of the electronic and control models (control command). Then, a characterization is done to highlight the optimization constraints that may affect the mechanical model. … …Journal of Mechatronics and Robotics, Vol. 8, Issue 1 · 26 Sep 2024 · 7,110 accessesView PDFCite
