Un antecedente imprescindible del Valle de los Caídos: la aportación de Manuel Abril en 1939
2021
En abril de 1939 veía la luz un artículo firmado por el crítico de arte Manuel Abril en el que abogaba por la existencia de un monumento para celebrar la victoria de la guerra y honrar a sus caídos. En esa misma fecha se dictó el decreto que disponía la erección de un monumento para perpetuar el recuerdo a los muertos en la Cruzada de Liberación, lo que supuso el primer paso para la construcción del Valle de los Caídos. Las coincidencias conceptuales y plásticas entre ambos monumentos, el propuesto y el ejecutado, son más que notorias. Es propósito de este trabajo ponerlas de manifiesto dentro del contexto histórico y conceder a la aportación de Abril la categoría de antecedente del monumen…
Brookite, the Least Known TiO2 Photocatalyst
2013
Brookite is the least studied TiO2 photocatalyst due to the difficulties usually encountered in order to obtain it as a pure phase. In this review, a comprehensive survey of the different methods available for preparing brookite powders and films is reported. Attention has been paid both to the most traditional methods, such as hydrothermal processes at high temperatures and pressures, and to environmentally benign syntheses using water soluble compounds and water as the solvent. Papers reporting the photocatalytic activity of pure and brookite-based samples have been reviewed.
Effect of total knee replacement surgery and postoperative 12 month home exercise program on gait parameters
2017
Abstract Objective To evaluate the effects of surgery and a postoperative progressive home exercise program on gait parameters among individuals operated with total knee arthroplasty. Design Single blinded randomized controlled trial. Subjects 108 patients (84 females, 24 males, mean age 69 years). Interventions Patients were equally randomized into an exercise group (EG) and control group (CG). The 12-months progressive home exercise program starting two months postoperatively was compared to usual care. Methods Gait analysis was performed using the Gaitrite electronic walkway system. In addition, knee extension and flexion strength were measured by a dynamometer preoperatively, and pain o…
Restoring Harmony in the Lifeworld? : Identity, Learning, and Leaving Preelite Sport
2020
Sport provides many youth participants with a central life project, and yet very few eventually fulfill their athletic dreams, which may lead them to disengage from sport entirely. Many studies have explored the processes of athletic retirement, but little is known about how youth athletes actually reconstruct their relationship with sport and embodiment postretirement. The authors explored these issues in the story of “Pilvi,” a Finnish alpine skier who disengaged from sport in her late adolescence. Employing an existential-phenomenological approach, they conducted six low-structured interviews with Pilvi, combined with visual methods, and identified key themes relating to the body, space,…
Visual saliency detection in colour images based on density estimation
2017
International audience; A simple and effective method for visual saliency detection in colour images is presented. The method is based on the common observation that local salient regions exhibit distinct geometric and and texture patterns from neighbouring regions. We model the colour distribution of local image patches with a Gaussian density and measure the saliency of each patch as the statistical distance from that density. Experimental results with public datasets and comparison with other state-of-the-art methods show the effectiveness of our method.
Cylindrical metal-coated optical fibre devices for filters and sensors
1996
Novel fibre-optic components suitable for sensor applications and wavelength filters are reported. The devices consist of a tapered fibre whose uniform waist has been coated with a thin layer of gold. The operation principle is the resonant excitation of a surface plasma mode of the metal film.
A MIDI sequencer that widens access to the compositional possibilities of novel tunings
2012
We present a new Dynamic Tonality MIDI sequencer, Hex, that aims to make sequencing music in and across a large variety of novel tunings as straightforward as sequencing in twelve-tone equal temperament. It replaces the piano roll used in conventional MIDI sequencers with a two-dimensional lattice roll in order to enable the intuitive visualization and dynamic manipulation of tuning.\ud \ud In conventional piano roll sequencers, a piano keyboard is displayed on the left side of the window, and white and black note lanes extend horizontally to the right, into which a user can draw a sequence of notes. Similarly, in Hex, a button lattice is displayed in its own pane on the left side of the wi…
Iron oxide-based magnetic photocatalysts: Recent developments, challenges, and environmental applications
2021
Abstract Magnetic separation of the solid photocatalyst from the reacting suspension has received great interest in recent research because it offers a suitable way for removing and recycling the heterogeneous photocatalytic material particles preventing the agglomeration and sedimentation during and after their use. The use of iron oxides such as heterogeneous photocatalysts is an appropriate choice to obtain a suitable photocatalyst easily separable from the fluid. This chapter presents a detailed investigation of iron oxide-based magnetic photocatalysts (IOMPs). We will discuss the required conditions for the synthesis of these photocatalysts, followed by their applications for the remov…
Project DyAdd : Nonlinguistic theories of dyslexia predict intelligence
2020
Two themes have puzzled the research on developmental and learning disorders for decades. First, some of the risk and protective factors behind developmental challenges are suggested to be shared and some to be specific for a given condition. Second, language-based learning difficulties like dyslexia are suggested to result from or correlate with also nonlinguistic aspects of information processing. In the current study, we investigated how adults with developmental dyslexia and ADHD as well as healthy controls cluster across various dimensions designed to tap the prominent nonlinguistic theories of dyslexia. Participants were 18–55-year-old adults with dyslexia (n = 36), ADHD (n = 22), and…
Montaje audiovisual e integración de la audiodescripción en la producción documental Estudio de caso del documental Vidas Olímpicas
2017
Este artículo es fruto de un proyecto de investigación multidisciplinar que une los ámbitos de la traducción audiovisual y la comunicación audiovisual: el proyecto ITACA (Inclusión social, Traducción audiovisual y Comunicación audiovisual), que gira en torno al concepto de producción audiovisual accesible o accessible filmmaking (Romero Fresco 2013). Este proyecto propone tener en cuenta las necesidades de las personas con discapacidad sensorial durante los procesos de preproducción, producción y postproducción de las obras audiovisuales para mejorar su nivel de accesibilidad. El presente trabajo se centra en descubrir si existen elementos del montaje audiovisual de una obra que podrían edi…
