The events caused by the COVID-19 pandemic forced educators to transition to a fully online education system. Therefore, the implementation of project-based learning (PBL) in education is not an easy task. However, since PBL offers students many learning benefits, the aim of this paper is to conduct a bibliometric analysis to measure the performance of using PBL in engineering courses. Two computer tools have been used to carry out the analysis: a) Scopus as a performance analysis tool and b) SciMAT to carry out the bibliometric analysis of content from scientific maps. The results show that the topic with the highest performance for the period 2000-2015 corresponds to the topic of engineering educators, with a h-index of 19, 157 linked articles and, 4815 citations. However, the transition to digital teaching is shown in the period 2016-2021, where e-learning systems represent a cross-cutting theme in the field of research. Therefore, the close relationship of the PBL methodology with engineering educators and the transition to virtual education is shown. However, it requires the integration of e-learning platforms. This is closely related to the driving topics shown in the strategic map for the 2016-2021 period, such as: ensuring the quality of teamwork; properly monitor learning experiences; enhance the focus on engineering design; and work on planning the design of the curriculum, to involve all the activities and evaluations of the educational goals.

Avoiding a resurgence of the COVID-19 virus is essential to minimize any risk of new infections in the population. Therefore, the objective of this research is to design an automatic temperature measurement and disinfection system as part of the biosafety protocols, to serve highly recurrent public and private establishments. The device is made up of two systems: the body temperature meter and the alcohol or disinfectant gel sprayer. The device design is done in Autodesk Inventor software, and the graphical interface of the system is developed in MATLAB software.The results determine that the temperature measurement data is displayed through a graphical interface, allowing, or preventing entry through an oscillating barrier.

Photovoltaic solar energy is one of the renewable, clean, and inexhaustible sources of energy. It is applied considering the basic needs for its operation in rural areas, where the supply of electricity is limited, as well as water. The main objective is to analyze the performance of a photovoltaic solar energy pumping system. The resultsshow that it is feasible to opt for a pumping system using this type of energy, based on its constant and high performance throughout the year. Therefore, these types of systems are recommended for family farming applications.
