https://minerva.autanabooks.com/index.php/Minerva/article/view/160
<p><span class="OYPEnA text-decoration-none text-strikethrough-none">The present work proposes the process for obtaining biodiesel from the transesterification of commercial sunflower oil. Characterization of the oil was carried out considering the acidity index, the peroxide index, the humidity, and the density, using the test method established by the Ecuadorian Technical Standard. To obtain biodiesel, the oil was transesterified, a process in which a triglyceride reacted with an alcohol to form esters and glycerol. The biodiesel obtained was characterized according to ASTM and EN standards. Parameters such as density, kinematic viscosity, humidity, and acid number were analyzed at 30 min, 45 min, and 60 min. It is concluded that sunflower oil is a good alternative for obtaining biodiesel, being within the established international standards.</span></p>Jenniffer Alexandra Agila TufinoIvette Andrea Moya ReinaAlcides Muentes Segundo GarciaRamón Eudoro Cevallos Cedeno

https://minerva.autanabooks.com/index.php/Minerva/article/view/161
<p><span class="OYPEnA text-decoration-none text-strikethrough-none">The objective of this work was to statistically test whether the free software GeoGebra is useful as a didactic tool to facilitate the teaching-learning process of linear ordinary differential equations (ODE). For this purpose, we worked with a group of engineering students who, in the first instance, were taught traditionally, while in the second phase, GeoGebra was used as a didactic support tool to improve understanding and facilitate the solution of these equations. The grades obtained by the students in each stage of the process were used to perform the Wilcoxon nonparametric test for two related samples applying the free software R, which showed that the didactic strategy implemented allowed the students to achieve a better understanding of the basic theory of linear ODEs.</span></p>Edisson LascanoAlba AlayFredy Rivadeneira

https://minerva.autanabooks.com/index.php/Minerva/article/view/162
<p>This study aimed to promote collaborative work as a pedagogical strategy to foster school coexistence in a group of three-year-old children. A mixed methodology was employed, with a pre-experimental longitudinal design of 36 children. An observation sheet was applied before and after<br>implementing the pedagogical strategy over five weeks. The results were analyzed through statistical techniques, using the T-Student hypothesis test processed in the statistical software SPSS version 0.25. The main findings reveal statistically significant differences in school coexistence when comparing the means of pre-experimentation (M=52.08) and post-experimentation (M=59.36). It can be asserted that the work positively impacted the children's school coexistence, improving their social and cognitive skills. It is recommended to continue exploring collaborative approaches to promote harmonious environments from the early stages.</p>Veronica Rocio Garcia VeraGeilert De la Pena Consuegra

https://minerva.autanabooks.com/index.php/Minerva/article/view/163
<p><span class="OYPEnA text-decoration-none text-strikethrough-none">This study analyzes the determinant factors of non-attendance to medical appointments through a mixed-methods approach. A survey was conducted with 200 patients, supplemented by semi-structured interviews to delve deeper into the reasons behind absenteeism. The logistic regression analysis results showed that transportation problems and long waiting times for appointments are the main factors influencing non-attendance. Variables such as age, gender, forgetting the appointment, work-related reasons, dissatisfaction with medical care, improvement in health status, and education level were not significant predictors. The study's limitations include the small sample size and the lack of consideration of patients by treatment type. Future research should focus on increasing the sample size and conducting longitudinal studies to evaluate the effectiveness of specific interventions.</span></p>Wilson Francisco Zambrano JimenezDivina Monserrate Macías QuirozJorge Andres Fernandez SanchezShaileen Mariela Zambrano Cevallos

<p><span class="OYPEnA font-feature-liga-off font-feature-clig-off font-feature-calt-off text-decoration-none text-strikethrough-none">This study analyzes the protection coordination of an electrical system using the ETAP software, which models each element based on the system’s single-line diagram. The initial conditions are established by considering the load levels of the elements and lines, corresponding to the presence of nominal loads. Next, a fault analysis is performed, followed by a protection coordination study that defines fault scenarios in different busbar systems and evaluates the performance characteristics of the protection devices. Finally, a techno-economic analysis is performed, incorporating historical energy consumption data of the industrial plant.</span></p>Luis Franklin Casa ChancusigJose Efren Barbosa Galarza Carlos Ivan Quinatoa Caiza

https://minerva.autanabooks.com/index.php/Minerva/article/view/165
<p><span class="OYPEnA font-feature-liga-off font-feature-clig-off font-feature-calt-off text-decoration-none text-strikethrough-none">Thyroid Dysfunction corresponds to the early phase of a thyroid disorder that predominantly affects middle-aged and elderly individuals. This research analyzes studies conducted in a laboratory, where the relationship between thyroid dysfunction and serum lipid levels was evaluated. The methodology was descriptive and cross-sectional, with a sample of 52 patients, from which 8 were excluded due to unusual findings in the thyroid examination that were unrelated to the requirements of this study. The results revealed a high percentage of patients with serum levels of total cholesterol and triglycerides above the upper normal limit. It is crucial to monitor and regulate thyroid function to prevent complications related to elevated blood lipid levels and to reduce the risk of developing cardiovascular diseases in affected individuals.</span></p>Darwin Gustavo Veliz Bazurto

https://minerva.autanabooks.com/index.php/Minerva/article/view/169
<p><span class="OYPEnA font-feature-liga-off font-feature-clig-off font-feature-calt-off text-decoration-none text-strikethrough-none">This work analyzes the options for repowering, reconfiguration, and automatic load transfer that a feeder can have. The study was carried out from the head of a distribution substation using the CYMDIST application, through which the failure rate, repair time, and availability and unavailability indices were determined. Using the "Reliability Analysis" module of the CYMDIST software, consumer-oriented reliability indices are obtained, allowing a reconfiguration and the optimal path to be identified in a reasonable analysis time. The main results show that the repair time should be shorter than the maneuvering time for reconnection. It was also possible to define the conditions for ensuring proper operation before and after the fault, the location of the automatic reconnection equipment, and the communication system used.</span></p>Cesar Augusto Taday AlvarezMauricio Eduardo Mullo PalloMauro Stalin Castro Yanez Carlos Daniel Mejia Banda
