Actividad física y deporte extraescolar: rendimiento escolar e índice de masa corporal (IMC)

Abstract

Objetivos: Conocer el perfil deportivo y educativo de la población y establecer la relación existente entre la Actividad Física y Deporte Extraescolar y el Índice de Masa Corporal (IMC) y las Notas Académicas. Material y Método: Se trata de un estudio, descriptivo, transversal, realizado sobre una población diana de 62 sujetos, de entre 6 y 12 años, a quienes se les aplicó un Cuestionario -que indagaba acerca de Variables de Identificación Familiares, Educativas, IMC y relacionadas con la Actividad Física y Deporte Extraescolar- estructurado, anónimo, voluntario y autoadministrado. Resultados y Conclusiones: Están siendo realizados.

On the Rate of Convergence of the 2-D Stochastic Leray- $$\alpha $$ α Model to the 2-D Stochastic Navier–Stokes Equations with Multiplicative Noise

“…In this section we introduce some notations that are frequently used in this paper. We will mainly follow the presentation of Cao and Titi [10].…”

“…However, only a few papers deal with the rate of convergence, see [10,15]. In [10] the rates of convergence of four α-models (NS-α model, Leray-α model, modified Leray-α model, and simplified Bardina model) in the two-dimensional (2D) case, subject to periodic boundary conditions on the periodic box [0, L] 2 are studied. The authors of [10] mainly showed that all the four α-models have the same order of convergence and error estimates; that is, the convergences in the L 2 -norms are all of the order O α L log( L α ) 1 2 as α L tends to zero, while in [15] the rate of convergence of order O(α) is obtained in a mixed L 1 − L 2 time-space norm with small initial data in Besov-type function spaces.…”

“…These results can be found in Theorem 4.1 and Theorem 4.2. We mainly combine the approaches used in [4] and in [10].…”
