Involvement of bread melanoidins in cellular pathways against ischemia
No full textComunicación presentada en: The 5th International Electronic Conference on Foods 2024, durante los días 28-30 de octubre de forma online.Ischemic hypoxia, a common condition that can cause neuronal damage, triggers multiple cellular pathways, including hypoxia-inducible factors and anti-apoptotic mechanisms. Using food industry by-products with antioxidant and anti-inflammatory properties, such as melanoidins, as functional ingredients allows their revalorization and may enhance neuronal survival. The scientific impact of this study also considered the bioaccessibility of these compounds to exert a beneficial effect.The authors thank to MICIU and ERDF (TED2021-132195B-I00
Design and usability of IndagApp: an app for inquiry-based science education
No full textLa indagación es una metodología didáctica que promueve el desarrollo de competencias científicas y el aprendizaje significativo de las ciencias. Sin embargo, su implementación en el contexto educativo español se enfrenta a diversas barreras, como la falta de recursos y formación docente. El objetivo de este estudio fue diseñar y evaluar la usabilidad de IndagApp, un recurso TIC que facilita la enseñanza de las ciencias por indagación con alumnado de 10 a 14 años de edad. Se utilizó un diseño de métodos mixtos convergentes, con un muestreo intencional compuesto por un panel de 14 expertos de distintas disciplinas. Los resultados cuantitativos mostraron una usabilidad elevada de la app, mientras que los cualitativos permitieron mejorar la interfaz del usuario, incluir estrategias de andamiaje y alinear el recurso con las demandas curriculares. A partir de este proceso se realizó una mejora de la app que, en su versión mejorada, consta de diez indagaciones que abordan contenidos centrales del nuevo currículo de la LOMLOE. Además, se han diseñado recursos de apoyo para su implementación, como programas-guía para el profesorado y fichas de clase imprimibles para el alumnado. En conjunto, este recurso se presenta como pertinente e innovador para la transposición didáctica de la indagación, brindando a la comunidad educativa e investigadora iberoamericana una herramienta valiosa para la enseñanza de las ciencias. Se propone el desarrollo de investigaciones que aborden el análisis del uso y la percepción de la usabilidad del recurso en potenciales usuarios del ámbito de la Educación Primaria y Secundaria.Inquiry is a didactic methodology that promotes the development of scientific competencies and the meaningful learning of science. However, its implementation in the Spanish educational context faces various barriers, such as the lack of both resources and teacher training. The objective of this study was to design and evaluate the usability of IndagApp; an ICT resource that facilitates the teaching of science by inquiry with students aged 10 to 14. A convergent mixed methods design was used, with an intentional sampling composed of a panel of 14 experts from different disciplines. The quantitative results showed high usability of the app, while the qualitative ones allowed for improving the user interface, including scaffolding strategies and aligning the resource with the curricular demands. From this process, an improvement of the app was made, which in its improved version consists of ten inquiries that address the central contents of the new LOMLOE curriculum. In addition, support resources have been designed for its implementation, such as guide programs for teachers and printable class sheets for students. Taken together, this resource is relevant and innovative for the didactic transposition of inquiry, providing the Ibero-American educational and research community with a valuable tool for the teaching of science. Future research delving into the usage and perceived usability among potential users in Primary and Secondary Education is warranted
El cenobio femenino de Vallbona de Les Monges, una adaptación histórica: del eremitismo a la conversión ecológica
Get PDFEl monasterio de Vallbona de les Monges ha sido desde su incorporación al Cister en 1175
el cenobio femenino más importante de Cataluña, recibiendo privilegios que le permitieron
erigirse como un centro eclesiástico independiente, siendo filial directa de Citeaux.
No obstante, con el paso de las centurias y, especialmente a partir del siglo XVI con el
Concilio de Trento hasta el siglo XXI, acontecerán numerosas dificultades donde bajo el
báculo de la abadesa las monjas han logrado una “adaptabilidad” al contexto histórico que
han prolongado la subsistencia de la vida monacal así como la buena conservación
patrimonial hasta nuestros días.Since 1175 when it became a membership of the Cister, the Vallbona de les Monges
monastery has been the Catalonia´s most important female abbay, receiving privileges that
allowed it to become as an independent catholic institution being a direct affiliated of
Citeaux.
However, through the centuries, and especially between the Trento Concilium in the XVI
century and the XXI century, the monastery had to face many difficulties, but under the
command of the abess, who knew how to adapt the monastic life of the nuns to the
historical context, achieved to prolong its activity and allowed to keep the heritage in
optimal condition
Antonio Fernández Alba e Desenho Arquitetônico
No full textLa dimensión artística e intelectual del arquitecto español Antonio Fernández Alba (Salamanca 1927-Madrid 2024), catedrático de la Escuela de Arquitectura de Madrid, miembro de la Real Academia Española y de la Real Academia de Bellas Artes de San Fernando ha sido objeto de numerosos reconocimientos durante su trayectoria profesional, que culminaron con la concesión de la Medalla de Oro de la Arquitectura del Consejo Superior de los Colegios de Arquitectos de España en 2002 y Premio Nacional de Arquitectura de España en 2003. En este artículo se profundiza en la relación de Antonio Fernández Alba con el dibujo que fue su lenguaje para crear y expresar la arquitectura. El análisis del ingente legado gráfico de apuntes, croquis y planos de arquitectura, así como los numerosos escritos del arquitecto revelan la importancia que para él tenía el acto de dibujar en el proceso ideación de la arquitectura. Además, Fernández Alba reconocía la autonomía estética del dibujo como una forma de expresión de la arquitectura superando su condición instrumental de documento técnico necesario para el desarrollo constructivo del edificio.The artistic and intellectual dimension of the Spanish architect Antonio Fernández Alba (Salamanca 1927-Madrid 2024), professor at the School of Architecture of Madrid, member of the Royal Spanish Academy and the Royal Academy of Fine Arts of San Fernando, has been recognized during his professional career, culminating with the award of the Gold Medal of Architecture by the Higher Council of Professional Associations of Architects of Spain in 2002 and the National Architecture Award of Spain in 2003. This article delves into the relationship of Antonio Fernández Alba with drawing, which was his language to create and express architecture. T he analysis of the vast graphic legacy of notes, sketches and architectural plans, and the numerous writings of the architect reveal the importance that the act of drawing had for him in the process of ideation of architecture. In addition, Fernández Alba recognized the aesthetic autonomy of drawing as a form of expression of architecture, overcoming its instrumental condition as a necessary technical document for the constructive development of the building.A dimensão artística e intelectual do arquiteto espanhol Antonio Fernández Alba (Salamanca 1927-Madrid 2024), professor da Escola de Arquitetura de Madrid, membro da Royal Spanish Academy e da Royal Academy of San Fernando, foi reconhecida sua carreira profissional, culminando com a atribuição da Medalha de Ouro de Arquitetura pelo Conselho Superior dos Colégios de Arquitetos de Espanha em 2002 e o Prémio Nacional de Arquitetura de Espanha em 2003.

An Extensive Performance Comparison between Feature Reduction and Feature Selection Preprocessing Algorithms on Imbalanced Wide Data
No full textThe most common preprocessing techniques used to deal with datasets having high dimensionality and a low number of instances—or wide data—are feature reduction (FR), feature selection (FS), and resampling. This study explores the use of FR and resampling techniques, expanding the limited comparisons between FR and filter FS methods in the existing literature, especially in the context of wide data. We compare the optimal outcomes from a previous comprehensive study of FS against new experiments conducted using FR methods. Two specific challenges associated with the use of FR are outlined in detail: finding FR methods that are compatible with wide data and the need for a reduction estimator of nonlinear approaches to process out-of-sample data. The experimental study compares 17 techniques, including supervised, unsupervised, linear, and nonlinear approaches, using 7 resampling strategies and 5 classifiers. The results demonstrate which configurations are optimal, according to their performance and computation time. Moreover, the best configuration—namely, k Nearest Neighbor (KNN) + the Maximal Margin Criterion (MMC) feature reducer with no resampling—is shown to outperform state-of-the-art algorithms.This work was supported by the Junta de Castilla y León under project BU055P20 (JCyL/FEDER, UE) and by the Ministry of Science and Innovation under project PID2020-119894GB-I00, co-financed through European Union FEDER funds.

The reconstruction has been carried out using 3D modelling software with the aim of generating an explanatory vídeo for the Museum of Burgos about this unique object and, in the future, to integrate it into Virtual Reality interactive experiences
The parish sacristies of the Salado valley: the unique iconographic and iconological program of the paintings in the sacristy of la Magdalena (Santamera, Guadalajara)
No full textEl desarrollo de los espacios auxiliares en las iglesias de la comarca del Salado, obispado de Sigüenza, parece responder a priori al modelo de sacristía dispuesto en Trento. Sin embargo, una primera aproximación a sus tipos y el análisis de la iconografía de las pinturas murales de la Magdalena de Santamera (Guadalajara), muestra que algunas de sacristías, más allá de ser espacios donde custodiar el ajuar sagrado, fueron concebidas por las instituciones eclesiásticas como lugares de adoctrinamiento y evidencia de la desconfianza que debían tener hacia los cristianos nuevos.The development of auxiliary spaces in the churches of the Salado region, bishopric of Sigüenza, appears at first glance to follow the model of the sacristy established in Trent. However, a pre-liminary examination of their types and the analysis of the iconography of the mural paintings of La Magdalena in Santamera (Guadalajara), shows that some sacristies, beyond being spaces for safeguarding sacred vestments, were conceived by ecclesiastical institutions as places for indoc-trination and evidence of the distrust they should have towards new Christians
