    El progreso tecnol贸gico y el desarrollo de sistemas inform谩ticos de las 煤ltimas d茅cadas, unido a su impacto en nuestra vida cotidiana, ha provocado un replanteamiento de las metodolog铆as de ense帽anza-aprendizaje en las aulas, permitiendo la incorporaci贸n en las aulas de las TICs y las TACs y as铆, favoreciendo el modelo TPACK, que implica el uso de contenidos educativos digitales en las aulas, por lo que se hace indispensable el desarrollo de la competencia digital de los docentes, que a su vez fomentar谩 el desarrollo de la competencia digital de los alumnos, garantizando una educaci贸n y un proceso de ense帽anza-aprendizaje adaptado a la sociedad del siglo XXI.Technological progress and the development of computer systems in recent decades, along with its impact on our daily lives has led to the emergence of the teaching-learning methodologies in the classroom, allowing the incorporation of ICT management and LTK in the classrooms, and thus favoring the TPACK model, which involves the use of digital educational content in the classrooms, so it is essential to the development of digital competence of teachers, which in turn promote the development of digital competence of students, thereby ensuring an education and teaching-learning process adapted to the XXI century

    Improvement of Bearing Capacity in Recycled Aggregates Suitable for Use as Unbound Road Sub-Base

    Recycled concrete aggregates and mixed recycled aggregates are specified as types of aggregates with lower densities, higher water absorption capacities, and lower mechanical strength than natural aggregates. In this paper, the mechanical behaviour and microstructural properties of natural aggregates, recycled concrete aggregates and mixed recycled aggregates were compared. Different specimens of unbound recycled mixtures demonstrated increased resistance properties. The formation of new cement hydrated particles was observed, and pozzolanic reactions were discovered by electronon microscopy in these novel materials. The properties of recycled concrete aggregates and mixed recycled aggregates suggest that these recycled materials can be used in unbound road layers to improve their mechanical behaviour in the long ter

    The objective of this practical exercise is to provide an amusing way to learn how to use verbs of change. First, students must describe in detail an image of a character (provided on cards with pictures of people or monsters on them). They then receive another card which describes a situation that causes their character to transform. Now the students must give another description of their character, paying particular attention to the transformations it has undergone

    Abstract. In this study the tools are analyzed to cause that the PyMEs looks for to be more competitive in the market. The different proposals will appear on the Models of the Innovation Process from already existing and they will focus in the variables that conform these models compatible to analyze each one of the proposals made by the different authors and to integrate a new proposal of variables as a hypothesis that integrates a Model that allows the Pymes of Nuevo Leon to be innovating. Resumen. En este estudio se analizan las herramientas para hacer que las PyMEs busquen ser m谩s competitivas en el mercado.

    Ranking the impact of human health disorders on gut metabolism: Systemic lupus erythematosus and obesity as study cases

    Get PDF
    Multiple factors have been shown to alter intestinal microbial diversity. It remains to be seen, however, how multiple collective pressures impact the activity in the gut environment and which, if any, is positioned as a dominant driving factor determining the final metabolic outcomes. Here, we describe the results of a metabolome-wide scan of gut microbiota in 18 subjects with systemic lupus erythematosus (SLE) and 17 healthy control subjects and demonstrate a statistically significant difference (p < 0.05) between the two groups. Healthy controls could be categorized (p < 0.05) based on their body mass index (BMI), whereas individuals with SLE could not. We discuss the prevalence of SLE compared with BMI as the dominant factor that regulates gastrointestinal microbial metabolism and provide plausible explanatory causes. Our results uncover novel perspectives with clinical relevance for human biology. In particular, we rank the importance of various pathophysiologies for gut homeostasis.The present investigation was funded by the Spanish Ministry of Economy and Competitiveness and the Federal Ministry of Education and Research (BMBF) within the ERA NET PathoGenoMics2 program, grant number 0315441A.
