La variedad lingüística ecuatoriana a través del podcast educativo
(Ecuador: Latacunga: Universidad Técnica de Cotopaxi (UTC), 2024-08) Alajo Anchatuña, Andrea Salomé; Guagchinga Chicaiza, Nelson Wilfrido
Ecuador is a country with great linguistic diversity, with 14 official indigenous languages in addition to Spanish. This study focuses on the use of educational podcasts to teach fifth grade basic education students about the linguistic variety in Ecuador. The methodology of this research is qualitative, which included literature review, document analysis and interviews with experts. The study found that educational podcasts can be an effective tool for teaching students about the linguistic variety in Ecuador. The students who participated in the study showed greater knowledge of the different varieties of Spanish spoken in the country, as well as a greater interest in the culture and history of Ecuador. The research concludes that the use of educational podcasts can be an effective strategy to promote learning of the linguistic variety in Ecuador.

Desarrollo de indicadores de sostenibilidad ambiental como estrategia de protección y recuperación del páramo San Isidro, Cantón Pujilí, Provincia de Cotopaxi
(Ecuador: Cotopaxi: Latacunga: Universidad Técnica de Cotopaxi (UTC), 2024-08) Mena Pástor, Johny Adrián; Cajas Cayo, Isaac Eduardo
The project focuses on the development of environmental sustainability indicators as a protection and recovery strategy for the San Isidro páramo in Pujilí Canton, Cotopaxi Province. The main objective of this project was to develop environmental sustainability indicators as a protection and recovery strategy for the San Isidro páramo, Pujilí Canton. Specific objectives included the diagnosis of the current state of the páramo, the development of a local model using the PER (Pressure, State, Response) methodology, and the generation of environmental sustainability indicators. The methodology employed combined qualitative techniques, including the use of geospatial technologies such as the Global Positioning System and Geographic Information Systems for the collection and spatial analysis of environmental and socioeconomic data. A participatory approach was applied, integrating the perspective of the local community in the development of indicators. The results revealed a significant interdependence between the ecological health of the páramo and the socioeconomic well-being of the surrounding communities. The twenty-four proposed sustainability indicators reflect this relationship, covering aspects such as water quality, vegetation cover, biodiversity and changes in land use. The project highlights the usefulness of environmental sustainability indicators in effectively monitoring the ecological health of the San Isidro páramo and in promoting informed environmental management. The adoption of these indicators by the Prefecture of Cotopaxi and the GAD of Pujilí is recommended, in order to integrate them into their conservation policies and practices, ensuring a holistic and effective approach to environmental sustainability. This initiative represents a significant step towards the long-term conservation of one of the most valuable and vulnerable ecosystems, providing a replicable model for other protected areas in Ecuador and in the Andean region. The implementation of the indicators will allow local authorities and stakeholders to have a clearer and more quantifiable understanding of the impacts of human activities on the páramo ecosystem, favoring evidence-based decision-making for its management and restoration.

Toxicidad y eficacia de un Bioinsumo a base de extracto vegetal de Verbenaceae Essential Oil para el control de ácaros (Oligonychus sp.) del cultivo de aguacate
(Ecuador: Latacunga: Universidad Técnica de Cotopaxi (UTC), 2024) Muñoz Cachago, Mauro Daniel; Jácome Mogro, Emerson Javier
Los bioinsumos a base de extractos vegetales son propuestas interesantes para el control de plagas por su menor impacto ambiental y apoyo para el manejo de resistencia de las plagas, por ello el presente trabajo plantea caracterizar un biosinsumo a base de extracto vegetal de Verbenaceae Essential Oil comercial a través de Cromatografia de Gases-masas y establecer el nivel de control del producto a distintas concentraciones 0, 1, 2 y 3 mL/L, sobre ácaros (Oligonychus perseae), identificados en hojas de aguacate a nivel del laboratorio con un seguimiento en el tiempo a 0, 24, 48 y 72 horas después de la aplicación por atomización y el efectos sobre los estadios de desarrollo de estos tetraníquidos; huevos, ninfas y adultos. Los resultados obtenidos permitieron identificar que el principal componente de este extracto comercial es el timol con un contenido promedio determinado en las muestras de materia prima del 24,59%, con el cual se prepara el bioinsumo y se determina por el mismo método cromatográfico en 3 muestras de producto un valor promedio de 13,2 g/L de timol. Los resultados de la acción acaricida son: a 1 mL/L se alcanza un 46% de muerte promedio a 2 mL/L 78% y a 3 mL/L un 86% de muerte a las 24 horas después de la aplicación finalmente se determina que el mejor tratamiento es a 2 mL/L en los estadios de huevos, ninfas y adultos alcanzando valores sobre el 97% datos que verifican la acción acaricida del bioinsumo a base de extracto vegetal comercial Verbenaceae Essential Oil.

Evaluación de pérdidas de potencia activa en el sistema eléctrico de la Empresa Eléctrica Quito (EEQ) aplicando un Algoritmo de optimización
(Ecuador: Latacunga: Universidad Técnica de Cotoapaxi (UTC), 2024-08) Pereira Herrera, Luis Andrés; Saraguro Ramírez, Roberth Alcides
This research proposes to develop a methodology based on the mean-variance mapping optimization (MVMO) algorithm to reduce the active power losses of the sub-transmission system of Empresa Electrica Quito (EEQ), determining the best operating point of the system, considering the state of tap’s of the transformers, the capacitor banks and the contribution of reagents from the generation plants that EEQ currently has. The same ones when operating in a proper way lead to reduce the value of active power losses in the network, thus improving the operating conditions of the EEQ’s Electrical Power System.

Evaluación preliminar de la aplicación de rayos ultravioleta c (uvc) durante el proceso de poscosecha para disminuir los daños causados por botrytis (botrytis cinerea) en rosas.
(Ecuador: Latacunga: Universidad Técnica de Cotopaxi (UTC), 2024-08) Loachamín Tipán, Tatiana Nataly; León Antonio
Botrytis cinerea is a fungal disease that affects export roses. Currently, the common method to minimize the damage caused by Botrytis cinerea is the use of synthetic fungicides, however, continuous and uncontrolled application generates resistance by the pathogen. This study aims to provide other control alternatives through the use of Ultraviolet Rays (UVC), as an alternative to the use of chemical products that generate cross-resistance and environmental contamination. This study was carried out at the Floricultural Company Matiz Flowers Cía. Ltda. located in the Parish of Mulaló, Canton Latacunga. The research was carried out in two phases. The first was exploratory in nature. The damage caused by UVC irradiation was evaluated at different times (0, 5, 7.5, 10, 12.5, 15 min) of exposure to the flower buds of 7 rose varieties: Mondial, Pink Floyd, Fredoom, Hermosa, Atomic, Boulevar, Sweetness. In the second phase, the effect of 6 times (0, 5, 7.5, 10, 12.5, 15 min) of exposure of the buds to UVC rays was evaluated in order to evaluate the control of Botrytis cinerea in the buds of the Mondial and Pink Floyd varieties susceptible to Botrytis cinerea and of commercial interest to the company. Initially, prior to exposure to UVC rays, the flower buds received the washing treatments normally carried out by the Company, including the chemical alternative. In the second part, the buds were only washed with water. In general, in the exploratory phase, it was determined that the Mondial variety did not show damage due to exposure to UVC rays, while the Pink Floyd variety shows burning of the petals after 5 minutes of exposure to UVC rays, however, it is one of the varieties of greatest commercial interest and susceptible to attack by Botrytis cinerea. All the treatments under study were placed in a humid chamber for 3 days and the percentage of damage and the number of spots caused by Botrytis cinerea were recorded. In general, it was determined that the longer the exposure time to UVC rays on the flower buds, the lower the number of spots caused by Botrytis cinerea in the two varieties under study during the post-harvest process. They also showed significant differences between the two varieties.
