ABSTRACT
The application of radio frequency (RF) vacuum electronics for the betterment of the human condition began soon after the invention of the first vacuum tubes in the 1920s and has not stopped since. Today, microwave vacuum devices are powering important applications in health treatment, material and biological science, wireless communication-terrestrial and space, Earth environment remote sensing, and the promise of safe, reliable, and inexhaustible energy. This article highlights some of the exciting application frontiers of vacuum electronics.
ABSTRACT
Para desarrollar un curso o asignatura a través de la educación a distancia utilizando la plataforma Moodle, es preciso dominar los recursos que esta ofrece; aunque sin el conocimiento del contenido, de pedagogía y una experiencia práctica de impartición tradicional de la materia, no es posible lograrlo con posibilidades de éxito. Es propósito de los autores socializar algunas acciones metodológicas sencillas, conformadas por ellos y aplicadas ya en su práctica docente, las que pueden ser útiles a los que se inician en la virtualización del proceso enseñanza aprendizaje.
To develop a course or subject through distance learning using the Moodle platform, it is necessary to master the resources that it offers; although without knowledge of the content, pedagogy and a practical experience of traditional teaching of the subject, it is not possible to achieve it with any chance of success. It is the purpose of the authors to socialize some simple methodological actions, formed by them and already applied in their teaching practice, which can be useful to those who are starting out in the virtualization of the teaching-learning process.
