Analysis of the covers of textbooks of Primary Physical Education
2017
Esta investigación analiza las imágenes del cuerpo humano y el tipo de actividad física que practica en las portadas de los libros de texto del área de Educación Física (EF) en Educación Primaria (EP), para determinar si reproducen y transmiten estereotipos en relación al sexo, raza, cuerpo, discapacidad y actividad física en función del currículum. La muestra universo consta de 30 portadas, publicadas bajo la Ley Orgánica de Educación (LOE). Los resultados muestran portadas preferentemente dibujadas y en color, los protagonistas de la actividad física son niños y niñas conjuntamente (agrupación mixta), pero a la vez permanecen estereotipos de raza (blanca) y somatotipo (ectomorfo) realizan…
Importance of Strategic Social Media Marketing
2017
Technological innovation has grown at an unprecedented rate over the past couple of decades, creating multiple opportunities for marketing in online settings. The proliferation of social media helps customers become more empowered and engaged in their brand interactions, while also providing them with new tools in their search, evaluation, choice and purchases of marketing offerings. Consequently, these developments are influencing marketing practices, both strategically, and tactically. Nowadays, social media has developed in an essential part of marketing strategy for its ability to generate co-created value, to interactively connect brands to consumers, to monitor brand-related discussio…
A new member of the fusaricidin family – structure elucidation and synthesis of fusaricidin E
2017
Two hitherto unknown fusaricidins were obtained from fermentation broths of three Paenibacillus strains. After structure elucidation based on tandem mass spectrometry and NMR spectroscopy, fusaricidin E was synthesized to confirm the structure and the suggested stereochemistry. The synthesis was based on a new strategy which includes an efficient access to the 15-guanidino-3-hydroxypentadecanoyl (GHPD) side chain from erucamide.

The castle's Hermitage of Yecla (Region of Murcia) constituted during the 13th to 16th centuries the first parish of the population, hosting a triptych-shaped altarpiece presided over by a tempera painting on wood of Our Lady of Humility or "Virgo Lactans", dated around 1370 and attributed to the painter Barnaba da Modena, which was the titular image of the mentioned temple under the title of Our Lady of the Incarnation, until at the end of the 18th century it changed ownership for the Conception of Our Lady. The table at averages of the eight hundred was placed in an a loft, appropriating it at the beginning of the 20th century by the retired military Pascual Spuche y Lacy, who sold it aro…
Global Europe
2013
Nicolas Levrat realiza un recorrido histórico por la conformación del Instituto Europeo y su relación con el proyecto de integración de la Unión Europea, primero Comunidad Económica y posteriormente ampliada a Unión Política. Los principales trazos del Instituto hasta su integración en la Universidad de Ginebra propician un conjunto de actividades tendientes a un proyecto intelectual-político y cultural más amplio.
Les racines plurielles de l'Europe. De la pertinence d'étudier aujourd'hui les racines de l'Europe
2013
El proceso de configuración de la Unión Europea no ha de verse como el camino hacia una entidad política homogénea, sino como una puesta en valor de la especificidad de cada pueblo: la idea de «unidad en la diversidad». Resulta más productivo identificar y atender a estas diversidades que buscar los rasgos de las trayectorias históricas que convergen en determinados momentos. Así, el uso del concepto «raíces europeas» nos remite a un proceso de integración que va modificando las bases de los primeros pasos de la construcción de la Unión, dado que las raíces fortalecen el tronco (botánico y político-cultural) a la vez que se extienden por la superficie, dando lugar a nuevos brotes
Active-passive decentralized H∞ control for adjacent buildings under seismic excitation
2011
Author's version of a chapter in the book: Proceedings of the 18th IFAC World Congress 2011. Also available from the publisher at: http://dx.doi.org/10.3182/20110828-6-IT-1002.01192 In this paper, a control strategy to reduce the vibrational response of adjacent buildings under seismic excitation is presented. The proposed strategy combines passive linking elements with an active decentralized H∞ control system. The overall active-passive control system admits decentralized design and operation, and achieves an excellent vibrational reduction when the active control system works; in case of a full or partial failure of the active control system, a remarkable reduction in the vibrational res…

Robust delay-dependent H∞ control of uncertain time-delay systems with mixed neutral, discrete, and distributed time-delays and Markovian switching p…
2011
Author's version of an article published in the journal: IEEE Transactions on Circuits and Systems I: Regular Papers. Also available from the publisher at: http://dx.doi.org/10.1109/tcsi.2011.2106090 The problem of robust mode-dependent delayed state feedback H ∞ control is investigated for a class of uncertain time-delay systems with Markovian switching parameters and mixed discrete, neutral, and distributed delays. Based on the LyapunovKrasovskii functional theory, new required sufficient conditions are established in terms of delay-dependent linear matrix inequalities for the stochastic stability and stabilization of the considered system using some free matrices. The desired control is …
Combined dynamics of the 500–600 nm leaf absorption and chlorophyll fluorescence changes in vivo: Evidence for the multifunctional energy quenching r…
2021
Carotenoids (Cars) regulate the energy flow towards the reaction centres in a versatile way whereby the switch between energy harvesting and dissipation is strongly modulated by the operation of the xanthophyll cycles. However, the cascade of molecular mechanisms during the change from light harvesting to energy dissipation remains spectrally poorly understood. By characterizing the in vivo absorbance changes (Delta A) of leaves from four species in the 500-600 nm range through a Gaussian decomposition, while measuring passively simultaneous Chla fluorescence (F) changes, we present a direct observation of the quick antenna adjustments during a 3-min dark-to-high-light induction.
