Videoblogging in secondary education language and literature classroom. A practical design

Este artículo ofrece estrategias para la alfabetización mediática, informacional y tecnológica a través del uso del videoblog en el aula de Lengua y Literatura de Secundaria. El objetivo es dar, con ello, respuesta a una demanda educativa actual: encontrar fórmulas para fomentar una competencia comunicativa integral en los nuevos entornos multimedia, a la vez que se desarrolla una actitud crítica sobre el consumo de información tradicional y digital. Los primeros resultados obtenidos de la práctica educativa puesta en marcha con alumnos de 3º de la E.S.O. reflejan en general la adquisición, por parte de los alumnos, de habilidades relacionadas con la competencia comunicativa-digital en el siglo XXIThis paper offers strategies to enhance media, informational and digital literacy through the use of videoblog in Language and Literature classroom. The aim is to meet a current educative demand: finding formulas to encourage a comprehensive communicational competence for new multimedia environments, at the same time that promotes a critic attitude for traditional and digital information consumption. The tentative results of the educational practice that has been developed among the students of 3rd of E.S.O. show that students acquired skills related to the communicative and digital competence in the 21st centur

Comparative effects of macro-sized aluminum oxide and aluminum oxide nanoparticles on erythrocyte hemolysis: influence of cell source, temperature and size

Al2O3 is the most abundantly produced nanomaterial and has been used in diverse fields, including the medical, military and industrial sectors. As there are concerns about the health effects of nanoparticles, it is important to understand how they interact with cells, and specifically with red blood cells. The hemolysis induced by three commercial nano-sized aluminum oxide particles (nanopowder 13 nm, nanopowder <50 nm and nanowire 2-6 nm × 200-400 nm) was compared to aluminum oxide and has been studied on erythrocytes from humans, rats and rabbits, in order to elucidate the mechanism of action and the influence of size and shape on hemolytic behavior. The concentrations inducing 50% hemolysis (HC50) were calculated for each compound studied. The most hemolytic aluminum oxide particles were of nanopowder 13, followed by nanowire and nanopowder 50. The addition of albumin to PBS induced a protective effect on hemolysis in all the nano-forms of Al2O3, but not on Al2O3. The drop in HC50 correlated to a decrease in nanomaterial size, which was induced by a reduction of aggregation Aluminum oxide nanoparticles are less hemolytic than other oxide nanoparticles, and behave differently depending on the size and shape of the nanoparticles. The hemolytic behavior of aluminum oxide nanoparticles differs from that of aluminum oxide

Impact of the COVID-19 lockdown on routine childhood vaccination coverage rates in Catalonia (Spain): a public health register-based study

COVID-19; Health lockdown; Vaccination coverageCOVID-19; Confinamiento sanitario; Cobertura de vacunaciónCOVID 19; Confinament sanitari; Cobertura de vacunacióObjective: The aim of this study was to determine the impact of the lockdown measures adopted during the COVID-19 pandemic on routine childhood vaccination coverage rates in Catalonia (Spain) and to estimate its recovery once the progressive return to 'normalcy' had begun. Study design: We conducted a public health register-based study. Methods: Routine childhood vaccination coverage rates were analysed in three periods: a first pre-lockdown period (from January 2019 to February 2020), a second lockdown period with full restrictions (from March 2020 to June 2020), and, finally, a third post-lockdown period with partial restrictions (from July 2020 to December 2021). Results: During the lockdown period, most of the coverage rates remained stable, concerning the pre-lockdown period; however, when comparing the vaccination coverage rates in the post-lockdown period to the pre-lockdown period, we observed decreases in all types of vaccines and doses analysed, except for coverage with the PCV13 vaccine in 2-year-olds, which experienced an increase. The most relevant reductions were observed in measles-mumps-rubella and diphtheria-tetanus-acellular pertussis vaccination coverage rates. Conclusions: Since the beginning of the COVID-19 pandemic, there has been an overall decline in routine childhood vaccine coverage rates, and the pre-pandemic rates have not yet been recovered. Immediate and long-term support strategies must be maintained and strengthened to restore and sustain routine childhood vaccination

Experimental verification of memristor-based material implication NAND operation

Memristors are being considered as promising devices for highly dense memory systems as well as the potential basis of new computational paradigms. In this scenario, and in relation with data processing, one of the more specific and differential logic functions is the material implication logic also named as IMPLY logic. Many papers have been published in this framework but few of them are related with experimental works using real memristor devices. In the paper authors show the verification of the IMPLY function by using $\mathrm{Ni}/\mathrm{HfO}_{2}/\mathrm{Si}$ manufactured devices and laboratory measurements. The proper behavior of the IMPLY structure (2 memristors) has been shown. The paper also verifies the proper operation of a two-steps IMPLY-based NAND gate implementation, showing the electrical behavior of the circuit in a cycling operation. A new procedure to implement a NAND gate that requires only one step is experimentally shown as well.Postprint (author's final draft
