Residents of nursing homes have been significantly affected by COVID-19 in Spain. The factors that have contributed to the vulnerability of this population are very diverse. In this study, physical agents, chemical pollutants, population density and different capacities of residences were analysed to understand their influence on the number of elderly people who have died in geriatric centres in different autonomous communities (AACCs) of Spain. A statistical analysis was carried out on the variables observed. The results show that many residences with a larger number of deaths were private, with some exceptions. Physical agents and pollutants were found to be determining factors, especially for the communities of Extremadura and Castilla–La Mancha, although the large number of factors involved makes this study complicated. The compromise between air quality and energy efficiency is of great importance, especially when human health is at stake.

It can be broadly considered that academic factors in general, and the quality of teaching in particular, contribute significantly to academic failure, although they are not the only important factors. Moreover, academic factors are, at least theoretically, the most easily alterable through the intervention of university teachers. This chapter proposes incorporating microlearning into physics teaching in order to favour students' understanding of it. Specifically, it presents a series of considerations for the design of effective micro-modules for teaching physics to general education students. The first part of the chapter discusses the concept of microlearning and highlights the advantages of its implementation in the classroom. The second and last part summarises six important considerations when creating an effective micro-module and presents a concrete example developed by teachers at the Escuela Politécnica Superior de la Universidad CEU - San Pablo in Madrid, Spain.

RESUMEN El enfoque principal de este estudio es discutir la influencia de la longitud del proyectil en los resultados de un experimento de la barra Hopkinson de tracción (SHTB). Se han realizado simulaciones por medio de elementos finitos utilizando el software comercial ABAQUS en ensayos de tracción a altas velocidades de deformación en muestras de aleación de aluminio 7017T73 variando la longitud del proyectil. Los análisis por elementos finitos se han aplicado para simular los efectos de la variación de la longitud del proyectil en las mediciones obtenidas en las barras incidente, reflejada y transmitida. Se han obtenido diferentes velocidades de deformación, al variar la longitud del proyectil permaneciendo su velocidad constante. Los resultados de la simulación muestran que la longitud del proyectil tiene un efecto significativo en la tensión obtenida en la muestra y también en la curva de tensión-deformación. Se puede concluir que la longitud del proyectil es un factor que influye en los ensayos de tracción dinámica, ya que tiene un efecto significativo en la tensión obtenida dentro de la probeta. Las simulaciones también proporcionan información complementaria a los experimentos y una comprensión profunda del comportamiento de la probeta.

The study of earthquakes and their impact on buildings from the practical application of Physics in Architecture is essential to ensure the safety of building occupants in seismic zones. Models made with spaghetti and tested on a shaking table allow architects and engineers to experiment with different designs and materials to determine the best way to resist the vibrations produced by earthquakes. Teaching innovation and education play a fundamental role in the study of earthquakes and their impact on buildings through the practical application of Physics in Architecture. To ensure the safety of occupants in seismic zones, it is necessary to have well-trained and up- to-date professionals in the latest techniques and knowledge related to earthquake-resistant design.
