The effective use of UAVs in agriculture, especially crop-spraying drones, requires a more extended flight range. Batteries currently limit a drone’s flight time since purely electric drones tend to consume more electrical energy with their higher payload capacity. For this reason, the present project proposes the improvement of an Agras MG-1P octocopter drone batteries’ load supply through a load system consisting of a double-cylinder VVRC RCGF 70cc combustion engine and a KDE10218XF-105 brushless motor as a generator. The brushless motor operates as a generator since it weighs less than an alternator or generator. The weight is significant, and the octocopter can stay longer in the air. This project aims to increase the Agra MG-1P Octocopter UAVs flight time by more than two hours, as well as its payload, having a 9 l variable load of fumigant and a 4.4 kg load of added components,...

Interactive whiteboards are an educational tool widely adopted as part of the integration of Information and Communication Technologies (ICT) and cost reduction. This technology becomes more effective when teachers know and apply interactive teaching methods that can improve the results of the teaching-learning process. This research presents a training model for primary and high school teachers in Yanaquihua, Condesuyos, Arequipa. The proposed training model generated good results: teachers improved their interactive content-making skills by 29 percent. Also, 50 percent of the interactive content created by teachers is considered satisfactory quality. Only 11 percent of teachers needed to dedicate more effort to achieve the objectives. This document reports the importance, the limitations, and the results of applying the proposed training model to improve the performance and effectivene...

La utilización de recursos virtuales para facilitar el aprendizaje de habilidades y técnicas de investigación en estudiantes de pregrado es fundamental para su formación profesional. Por esa razón, el objetivo del artículo es determinar la influencia de las tutorías virtuales en la redacción de informes de investigación en estudiantes de carreras de negocios en la modalidad de educación virtual. El artículo describe un diseño de investigación descriptivo longitudinal, analizando los resultados obtenidos por los estudiantes en la redacción de sus informes de investigación durante los años 2016, 2017, 2018 y 2019. Se evalúa cuantitativamente por los logros de aprendizaje de cada criterio definido y cualitativamente en función del juicio de experto de 8 docentes con experiencia en el desarrollo de asignaturas de investigación en pre y post grado. Los resultados muestran u...
