Research ArticleOpen accessIn the abstractEffect of Physical Treatments on the Promotion of Seed Germination in Green and Giant FoxtailsInagaki Hidehiro, Sakakibara TakumiThe difficulty of breaking seed dormancy in Setaria (foxtail) species presents a problem in using them as model plants. In the present study, we observed the structure of the seed coat surface of two Setaria species, the green foxtail (Setaria viridis) and the giant foxtail (Setaria faberi), using an electron microscope. In addition, we tested the effects of physical treatment … …American Journal of Agricultural and Biological Sciences, Vol. 15, Issue 1 · 25 Nov 2020 · 6,477 accessesView PDFCite
Research ArticleOpen accessIn the abstractRole of Clothing Insulation for Thermal Comfort: A Numerical Study using Bio-Heat Transfer ModelKabita Luitel, Dil Bahadur Gurung, Harihar Khanal, Kedar Nath UpretyClothing plays a major role in protecting the human body from cold and hot environment by working as an insulator. The physical factors such as conduction, convection, radiation, evaporation and the physiological factors such as blood flow and metabolism within the body together with clothing system help to maintain human thermal comfort and the human thermoregulatory system. On the other … …Journal of Mathematics and Statistics, Vol. 16, Issue 1 · 24 Dec 2020 · 8,032 accessesView PDFCite
Research ArticleOpen accessIn the abstractNovel De-Oiling of Oil-WaterEmmanuel Ewa Ekeng, Jonah Chukwuemeka AgunwambaThe study anchors on developing a mechanistic model for oil-water separation. Over the years, researchers have been working on how to improve the quality of produced water effluent especially from oil and gas operations sent to the receiving waters. Despite the standard set for compliance by regulatory bodies like united nation agency, ministry, departments and other agencies both state and … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 2 Sep 2020 · 6,945 accessesView PDFCite
Research ArticleOpen accessIn the abstractConstructing Gibbs Measure in a Rigorous WayFarida Kachapova, Ilias KachapovEquilibrium statistical mechanics studies mathematical models for physical systems with many particles interacting with an external force and with one another. In this paper we describe an interaction model that generalizes several of these models in one model. An infinite model is constructed as the limiting case of finite interaction models, that is as a thermodynamic limit. The key point … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 29 Oct 2019 · 6,591 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Curcumin and Physical Training on the Brain and Motor Performance of Rats with Cerebral IschemiaKarine Sthéfany Serpa Amaral Dias, Jonas Augusto Ramos, Bruno Mattiello Gomes et al.Brain ischemia is the second most deadly disease in the world and it has already been proven that mild and moderate physical exercises minimize the deleterious effects of this disease on the brain. Curcumin has also been considered a neuroprotective substance. Therefore, the goal of this study was to evaluate the effects of high-resistance training and curcumin on the brain … …Neuroscience International, Vol. 10, Issue 1 · 25 Apr 2019 · 7,765 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Model-Based Fault Detection Approach using Black Box ObserverM. Abdullah Eissa, R. R. Darwish, A. M. BassiunyMost of the emerging engineering systems lack the presence of explicit physical insights or prior knowledge that clearly depicts the model. In such cases, the conventional observer-based fault detection is difficult to be employed because of its observer gain tuning. Herein, black box behaviors arose as a promising trend that could overcome those challenges that appears due to lacking the … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 15 Mar 2019 · 6,613 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 · 7,108 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Integrated Approach to Modelling of Flood Hazards in the Rapidly Growing City of Osogbo, Osun State, NigeriaSuleiman Abdul-Azeez Adegboyega, Oluchi Christiana Onuoha, Komolafe Akinola Adesuji et al.In recent times, the swift and uncoordinated urban expansion in the medium sized city of Osogbo has increasingly encroached on the environmental sensitive areas. This uncoordinated exploitation of the ecological fragile areas for urban development has triggered urban flooding, which poses serious threat to human lives and properties in the city. This study therefore utilized geospatial technologies to generate flood … …Space Science International, Vol. 4, Issue 1 · 8 Jan 2018 · 13,829 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 · 645 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessing the Comparative Effectiveness of Ensemble CatBoost Versus XGBoost Models in Predicting Heart Disease OutcomesManivannan D., G. Gifta Jerith, G. Chandra Sekhar et al.Cardiovascular Diseases (CVDs) are a common form of heart disease that remains a significant global cause of mortality, responsible for more than 30% of all fatalities. Without intervention, the global fatality count is projected to reach 22 million by 2030. Arterial plaque buildup may impede blood flow, potentially causing heart attacks or strokes. A combination of risk causes, including lack … …Journal of Computer Science, Vol. 22, Issue 4 · 4 May 2026 · 1,544 accessesView PDFCite
