Research ArticleOpen accessIn the author namesComparison of Collinearity Indices for Linear Models in Agricultural TrialsDanny Villegas Rivas, José M. Palacios Sánchez, Cristina A. Alzamora Rivero et al.The deleterious consequences of collinearity in linear regression on the precision of estimators of regression coefficients and the interpretability of the fitted model are widely recognized. In this study, we compare several methodologies for assessing collinearity in linear models and explore the effect of outliers on collinearity. The robustness of collinearity measures (individual and overall) is validated through two detailed … …OnLine Journal of Biological Sciences, Vol. 24, Issue 2 · 28 Dec 2023 · 6,491 accessesView PDFCite
Research ArticleOpen accessIn the author namesFrozen Semen Quality of Kolbroek Boars Concerning Glutathione ConcentrationsLerato Deirdre Sehlabela, Masindi Lottus Mphaphathi et al.Glutathione (GSH) is an antioxidant that is being studied for its ability to improvecellular responses to semen preservation challenges. The research goal aimed toevaluate the impact of introducing different glutathioneconcentrations to boar semen freezing extender (0, 1, 5, and 10 mM) onthe Kolbroek boar sperm's quality after being frozen and thawed. For 2 h, thecollected sperm-rich fraction was chilled at … …American Journal of Animal and Veterinary Sciences, Vol. 18, Issue 1 · 1 Apr 2023 · 6,005 accessesView PDFCite
Research ArticleOpen accessIn the author namesAssessment of Efficient Thermal Conversion Technologies and HHV from Compositional Characteristics of Cassava Peelings, Plantain Peelings and Corn CobsSamomssa Inna, Oumarou Amadou Amadou, Jiokap Nono Yvette et al.The understanding of compositional characteristics permits to predict the efficient thermal conversion technologies and Higher Heating Value (HHV). Although HHV can be determined directly, many models have been proposed for HHV prediction. They are based on proximate, ultimate, and structural analysis and require much data collected. The present work assesses to predict efficient thermal conversion technologies and HHV of the … …Energy Research Journal, Vol. 13, Issue 1 · 27 Dec 2022 · 10,157 accessesView PDFCite
Review ArticleOpen accessIn the author namesUncrewed Ground Vehicles (UGVs) and Nature-Inspired Designed Robot DIGIT and SPOT: A ReviewMA Muktadir, Sun Yi, Sameer Hamoush et al.Researchers around the world are developing autonomous robot systems to assist humans with tedious, hazardous, complex, and time-consuming tasks. Today, autonomous robots are used for a variety of applications, ranging from delivering food to operating on patients. A robotic system can be operated with or without human assistance, depending on whether it is manned or unmanned. Additionally, the robot may … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 4 · 5 Dec 2022 · 6,745 accessesView PDFCite
Research ArticleOpen accessIn the author namesIsoquinoline Alkaloids and the Ionophore Monensin Supplemented Alone or Combined on Ruminal Fermentation and Nutrient Digestibility in Steers Fed a High-Energy DietJesús D. Urías-Estrada, Beatriz I. Castro-Pérez, Alfredo Estrada-Angulo et al.The aim of this experiment was to investigate the Influence of Alkaloids (IQA) and sodium Monensin (MON) supplementation on characteristics of ruminal fermentation, microbial protein synthesis and site and extend of digestion. For this, 4 cannulated steers were used in a 4×4 Latin square design. Treatments consisted of a high-energy basal diet supplemented with: (1) No additive (Control), (2) 15 … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 3 · 7 Oct 2021 · 6,580 accessesView PDFCite

Research ArticleOpen accessIn the author namesThe Vitamin A and E Forms Influence Differently the Plasma Vitamin Concentrations in Newly Received CalvesLorenzo Buenabad, Alberto Barreras, Alejandro Plascencia, Richard Avery ZinnTen Holstein steer calves (105±3 kg) were used to evaluate bioavailability of two Vitamin A or E forms, “natural” (EA1) or “synthetic” (EA2), based on plasma vitamin concentrations during a 3-d period post injection(subcutaneous). Plasma retinyl palmitate and plasma Vitamin A concentration (retinol equivalent of all forms) was greater 24 and 48 h (P<0.01) post injection of retinyl palmitate vs … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 2 · 31 May 2021 · 6,798 accessesView PDFCite
Research ArticleOpen accessIn the author namesXPS Studies of the SiO2 Substrates and Thermoelectric Thin Films of Sn/Sn+SnO2 under the Effects of the Different Thermal TreatmentsRichard Lagle, Stephen Egarievwe, Satilmis Budak, Mebougna DraboMultilayered thermoelectric Sn/Sn+SnO2 thin films were prepared using KJL DC/RF magnetron sputtering system under Ar gas plasma on the SiO2 substrates. The thicknesses of the fabricated thin films were found using Filmetrics UV thickness measurement system. The fabricated thin films were annealed at different temperatures for one hour to tailor the thermoelectric properties.
