Actividad física y calidad de vida en las personas mayores: estudio piloto PQS

Diferentes investigaciones muestran los efectos de la actividad física (AF) sobre la salud en los adultos mayores. Los objetivos principales de este estudio fueron: 1) evaluar la relación entre las recomendaciones de AF de la OMS y la percepción de calidad de vida en las personas mayores, y 2) valorar el efecto de un asesoramiento basado en la concienciación sobre el estilo de vida. Para ello participaron 28 adultos mayores (70,6±6,2) del municipio de Villanueva de Gállego (Zaragoza), que fueron distribuidos en grupo experimental (GE) y control. Todos los sujetos completaron un cuestionario de calidad de vida (EQ-5D) y de nivel de AF (RAPA). Los sujetos que practicaban AF regular presentaron mayores niveles de percepción de calidad de vida (p<0,05). La intervención basada en la concienciación podría ser una estrategia de utilidad en la mejora de la percepción de la calidad de vida de los adultos mayores

Light elements in stars with exoplanets

Light elements are important tracers of the internal stellar structure and kinematics. Li and Be are both burned in the stellar interiors but Be requires much higher temperatures and thus we can expect to measure Be abundances in stars which have no detectable Li in their atmospheres. The study of these elements can give us information about processes related to the angular momentum history of these stars, since rotation and angular momentum loss are important mechanisms responsible for the depletion of light elements. Additionally, if pollution has played an important role in determining the high-metal content of planet host stars, we would expect to find a similar or even higher increase in the Li and Be contents. We present Be and Li abundances in a sample of 69 stars with planets and 31 stars without known planetary companion, spanning a large range of effective temperature

Light elements in stars with exoplanets

It is well known that stars orbited by giant planets have higher abundances of heavy elements when compared with average field dwarfs. A number of studies have also addressed the possibility that light element abundances are different in these stars. In this paper we will review the present status of these studies. The most significant trends will be discusse

Layer-dependence of macroscopic and atomic magnetic correlations in Co/Pd multilayers

The development of multilayered materials with engineered magnetic properties compels a deep knowledge of physical properties at the atomic scale. The magnetic anisotropy is a key property in these materials. This work accounts for the magnetic anisotropy energy and its correlation with atomic properties of Co/Pd multilayers with the number of Co/Pd repetitions. Magnetometry measurements confirm stronger perpendicular magnetic anisotropy energies as the number of repetitions increases up to 40. However, the intrinsic anisotropy, related to the Co-Pd orbital hybridization and spin-orbit coupling, saturates at 15 repetitions. This finding is supported by x-ray magnetic circular dichroism analysis that reveals a direct correlation of the atomic Co and Pd orbital magnetic moments and the effective anisotropy of the system. The proximity effect that accounts for the Pd induced magnetization, along with the increasing Co moment, provides a suitable mechanism for the observed anisotropy energy layer dependence

Desarrollo de software sensible al contexto

Los Sistemas Informáticos fueron evolucionando desde aplicaciones científicas, comerciales y de escritorio, hasta el momento actual, en que pueden brindar servicios de acuerdo a la ubicación, tiempo y perfil del usuario. Las aplicaciones que brindan este tipo de funcionalidad se denominan Aplicaciones Sensibles al Contexto (CA – Context Aware), donde tienen predominancia los dispositivos móviles y el perfil del usuario. También va cambiando la forma de uso de la computadora, evolucionando desde brindar servicios a pedido del usuario hasta brindarlos en forma automática y extender la percepción y la interacción del usuario con el mundo real (realidad aumentada). La Ingeniería de Aplicaciones CA se ocupa de proporcionar un enfoque sistematizado para desarrollar este tipo de aplicaciones. El propósito de este proyecto es abarcar los aspectos de Ingeniería de Software para el desarrollo de aplicaciones CA.Eje: Ingeniería de SoftwareRed de Universidades con Carreras en Informática (RedUNCI

Small Bowel Enteroscopy - A Joint Clinical Guideline by the Spanish and Portuguese Small-Bowel Study Groups

The present evidence-based guidelines are focused on the use of device-assisted enteroscopy in the management of small-bowel diseases. A panel of experts selected by the Spanish and Portuguese small-bowel study groups reviewed the available evidence focusing on the main indications of this technique, its role in the management algorithm of each indication, and its diagnostic and therapeutic yield. A set of recommendations was issued accordingly.info:eu-repo/semantics/publishedVersio
