Charged anisotropic compact objects by gravitational decoupling

In the present article, we have constructed a static charged anisotropic compact star model of Einstein field equations for a spherically symmetric space-time geometry. Specifically, we have extended the charged isotropic Heintzmann solution to an anisotropic domain. To address this work, we have employed the gravitational decoupling through the so called minimal geometric deformation approach. The charged anisotropic model is representing the realistic compact objects such as $RXJ1856-37$ and $SAX J1808.4-3658(SS2)$. We have reported our results in details for the compact star $RXJ1856-37$ on the ground of physical properties such as pressure, density, velocity of sound, energy conditions, stability conditions, Tolman-Oppenheimer-Volkoff equation and redshift etc

Enseñar en competencias en educación infantil y primaria. La agenda telefónica

Las leyes educativas van cambiando, adaptándose a las necesidades de las nuevas sociedades presentes en nuestro entorno. Lo mismo debe suceder con nuestra forma de enseñar, de utilizar los recursos y de presentar los conocimientos y experiencias. Con la finalidad de trabajar en la línea de las competencias básicas, se presenta esta actividad, realizada conjuntamente con el alumnado de infantil y primaria. Se trata con ella de dar un sentido a la enseñanza de la numeración en el primer contacto que se tiene en la escuela

Molecular Mechanisms Used by Salmonella to Evade the Immune System

Human and animal pathogens are able to circumvent, at least temporarily, the sophisticated immune defenses of their hosts. Several serovars of the Gram-negative bacterium Salmonella enterica have been used as models for the study of pathogen-host interactions. In this review we discuss the strategies used by Salmonella to evade or manipulate three levels of host immune defenses: physical barriers, innate immunity and adaptive immunity. During its passage through the digestive system, Salmonella has to face the acidic pH of the stomach, bile and antimicrobial peptides in the intestine, as well as the competition with resident microbiota. After host cell invasion, Salmonella manipulates inflammatory pathways and the autophagy process. Finally, Salmonella evades the adaptive immune system by interacting with dendritic cells, and T and B lymphocytes. Mechanisms allowing the establishment of persistent infections are also discussed.European Regional Development Fund SAF2013-46229-R, SAF2016-75365-

La utilización de la bicicleta entre el alumnado universitario

El objetivo de este estudio es saber el uso de la bicicleta entre el alumnado de Maestro de Educación Primaria y Maestro de Educación Física de la Facultad de Educación de Huelva. La muestra se ha obtenido entre los estudiantes que cursan el primer curso de carrera de las especialidades descritas (n = 47), de los cuales, 26 eran de la especialidad de Educación Física y 21 de la especialidad de Educación Primaria. Se llevó a cabo un muestreo no probabilístico. Como instrumento se utilizó un cuestionario. El proceso de recogida de información constó de dos fases: la primera ponernos en contacto con los profesores de las asignaturas y en segundo lugar, la cumplimentación del cuestionario. Para el registro de los datos se utilizó el paquete estadístico SPSS v17.0. En primer lugar se realizó un análisis descriptivo de la situación actual y seguidamente un estudio ex postfacto. Todos los análisis estadísticos se realizaron con un nivel de significación de p ≤ 0,05.The objective of this study is to know the use of the bicycle among the student body of Elementary Education Teacher and Physical Education Teacher degrees of the School of Education of Huelva. The sample has been obtained among the students that study the first year of the degree of the described specialities (n = 47), of which, 26 were of the speciality of Physical Education and 21 of the speciality of Elementary Education. A non-probability sampling was carried out, with a questionnaire as the tool. The process of collecting information consisted of two phases: firstly, we have to get in contact with the teachers of the subjects, and secondly, the filling of the questionnaire. In order to register the data, a statistical package SPSS v17.0. was used. In the first place, a descriptive analysis of the actual situation was done, and continuously, a study ex post facto. All the statistic analysis were made with a level of significance of p ≤ 0,05
