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 PDF Cite

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 PDF Cite

Research ArticleOpen accessIn the author namesNON-INVASIVE OPTICAL METHOD FOR EPIDERMAL THICKNESS ESTIMATIONAdrian Pena, Miguel Arronte, Eduardo De Posada et al.A non-invasive method to determine epidermal thickness from the intensity of transmitted visible light is proposed. A simple model for passing light through the epidermis layers, then measuring what is transmitted back out of the surface, is implemented by using the Montecarlo method. Simulations revealed that the transmittance is linearly dependent on the thickness of the epidermis and so demonstrated … …OnLine Journal of Biological Sciences, Vol. 14, Issue 2 · 25 Jun 2014 · 7,478 accessesView PDF Cite

Research ArticleOpen accessIn the author namesA NOVEL ARTIFICIAL HYDROCARBON NETWORKS BASED SPACE VECTOR PULSE WIDTH MODULATION CONTROLLER FOR INDUCTION MOTORSHiram Ponce, Luis Ibarra, Pedro Ponce, Arturo MolinaMost of machine-operated industrial processes implement electric machinery as their work sources, implying the necessary improvement of control techniques and power electronics drivers. Many years have passed since the control conflicts related to induction motors have been overcome through torque-flux control techniques so their advantages over direct current motors have made them to be the most common electric actuator found … …American Journal of Applied Sciences, Vol. 11, Issue 5 · 26 Feb 2014 · 7,039 accessesView PDF Cite

Research ArticleOpen accessIn the author namesEr: YAG Laser Device for Taking Blood SamplesJosé L. Cabrera, Luis Ponce, Miguel Arronte et al.Problem statement: Secure methods for blood sampling which is performed at present by metallic lancets, has been a concern in the modern medicine in order to diminish the risk of contamination. A novel solution has appeared recently and consists in the use of laser pulses which ablates a tiny hole in skin. Approach: A laser device with Er: YAG active … …OnLine Journal of Biological Sciences, Vol. 8, Issue 1 · 31 Mar 2008 · 7,179 accessesView PDF Cite
