Comparación de modelos hidrológicos bidimensionales y semidistribuidos en una cuenca semiárida mediterránea
Get PDFThis study focuses on the comparison of different hydrological programs in a semiarid basin with the aim of providing an evaluation of their performance in the simulation of hydrological processes. For this purpose, two distributed or two-dimensional programs have been evaluated (Iber and HEC-RAS), and a semi-distributed program (HEC-HMS), considering three rainfall events recorded in the rain gauge network of the Confederación Hidrográfica del Segura and a synthetic event with a return period of 100 years. In addition, the behaviour of the models has been evaluated by exposing the digital terrain model to changes to better model it to the reality. The results show that, in general, the Iber model shows greater similarity of the simulated flows with respect to the gauged flows, and that the obstructions present in the basins analysed, on a large scale, do not have a significant influence on the results.Este estudio se centra en la comparativa de diferentes programas de modelización hidrológica en una cuenca semiárida con el objetivo de proporcionar una evaluación de su desempeño en la simulación de procesos hidrológicos. Para ello, se han evaluado dos programas de modelización distribuida o de enfoque bidimensional (Iber y HEC-RAS), y un programa de modelización semidistribuida (HEC-HMS), considerando tres eventos lluvia registrados en la red de pluviómetros de la Confederación Hidrográfica del Segura y un evento sintético de período de retorno de 100 años. Adicionalmente, se ha evaluado el comportamiento de los modelos al someter el modelo digital del terreno a cambios para una mejor modelización de la realidad. Los resultados demuestran que, en general, el modelo Iber presenta mayor similitud de los caudales simulados con respecto a los aforados, y que las obstrucciones presentes en las cuencas analizadas, a gran escala no ejercen influencia remarcable en los resultados
Análisis de actuaciones en la zona agrícola de las cuencas Sur del Mar Menor con el objetivo de mejorar el estado ecológico de la laguna
Get PDFAgriculture is considered the main source of diffuse pollution, being nitrogen and sediments its main environmental impacts. Therefore, an improvement of the current management practices of these areas is crucial. In that sense, this study is focused on the southernmost catchments of the Mar Menor, an area which is under threat due to diffuse export of nitrogen and sediments. Hence, this study evaluates the effectiveness of several best management practices based on Law 3/2020, de recuperación y protección del Mar Menor para el control de las descargas de nitrógeno y sedimentos a la laguna. Results showed that being totally compliant with Law 3/2020 significantly reduce the production of sediments to the lagoon, as well as the surface nitrogen export and nitrate leaching.La agricultura es una de las principales fuentes de contaminación difusa, cuya contaminación por nitrógeno y sedimentos de las son los principales impactos ambientales. Es por ello, que una adecuada gestión de estas zonas es necesaria. El presente estudio se llevó a cabo en la cuenca más meridional del Mar Menor, que se encuentra amenazado por la exportación difusa de nutrientes y sedimentos. Es por ello que este estudio evalúa la efectividad de varias actuaciones basadas en la Ley 3/2020, de recuperación y protección del Mar Menor para el control de las descargas de nitrógeno y sedimentos a la laguna. Los resultados de estas simulaciones mostraron que con el cumplimiento completo de la Ley 3/2020 es posible reducir de forma significativa la producción de sedimentos a la laguna, así como la exportación de nitrógeno en superficie y la lixiviación de nitratos
Las murallas históricas de la ciudad de Oviedo, España
Get PDFThe intervention in the section of Oviedo city wall on calle Paraíso has led to its recovery and valorization, raising the profile of this Asset of Cultural Interest, which is key to understanding the formation and evolution of the city itself and was declared a historic-artistic monument by Decree on 3 June 1931. This walled city was chosen by Alfonso II in the 9th century as the seat for the court of the Asturian monarchy, as well as the departure point for the first pilgrimage to Compostela to see the newly discovered sepulchre of the Apostle Santiago. Alfonso X ordered the wall to be built at the height of the Reconquest. This article analyses the legal and heritage situation prior to intervention and contractual needs, as well as the progression of the construction of the wall, technical treatments, and project decision-making by the multidisciplinary team led by the architect José Ramón Fernández Molina.La intervención en el tramo de la calle Paraíso de la muralla de Oviedo ha permitido su recuperación y puesta en valor, dando a conocer ampliamente este Bien de Interés Cultural (declarado monumento histórico-artístico por Decreto de 3 de junio de 1931), indispensable para entender la propia conformación y evolución de la ciudad. Una ciudad cercada por un recinto murado a la que Alfonso II en el siglo IXtrasladó la corte de la monarquía asturiana, y desde la cual se iniciaría la primera peregrinación a Compostela para visitar el sepulcro recién descubierto del apóstol Santiago. Siglos más tarde, en plena Reconquista, Alfonso X ordenaría construir una nueva cerca. En el presente artículo se analiza la situación jurídica y patrimonial previa a la reciente intervención, las necesidades contractuales, así como la evolución de la fábrica, los tratamientos técnicos y las decisiones proyectuales adoptadas por el equipo pluridisciplinar comisionado, encabezado por el arquitecto José Ramón Fernández Molina
Un frágil monumento. La restauración del complejo de la Tumba Brion: cuestiones y reflexiones
Get PDFThis work aims to illustrate difficulties in conservation and intervention with regard to Carlo Scarpa’s exposed reinforced concrete, which is characterised by unique formal features. The case study of the Brion Tomb (1969-78), designed by Carlo Scarpa (1906-1978), is exceptional for its monumental character, along with its designer’s desire to envisage its ageing, but not its deterioration, over time. In this sense, the almost exclusive use of reinforced concrete for the building and the choice of certain experimental technical solutions place this architectural complex within the general context of problems related to the restoration of contemporary architecture, due to the theoretical and operational difficulties in defining interventions for its conservation. The restoration of this complex, which was completed in 2020, was an extraordinary opportunity to reflect on the methods and limits of conservation work, and to update technical capabilities to the current state of the art.Este artículo pretende mostrar los desafíos en la conservación e intervención de una obra de hormigón armado visto que goza de valores formales únicos. El estudio de caso de la Tumba Brion (1969-78) de Carlo Scarpa (1906-1978) resulta excepcional por su carácter monumental, pero también por el hecho de haber tenido en cuenta su progresivo envejecimiento con el paso del tiempo, aunque no su deterioro. En este sentido, el uso casi exclusivo de hormigón armado y la elección de algunas soluciones técnicas experimentales encuadran este complejo arquitectónico entre los retos de la restauración de la arquitectura contemporánea, debido a las dificultades teóricas y operativas de definir una intervención de conservación. La restauración de este complejo, finalizada en 2020, supuso una oportunidad extraordinaria para reflexionar sobre la metodología y los límites de las intervenciones de conservación, así como para actualizar los métodos técnicos disponibles hoy en día
Social Justice Education as an Intercultural Experience for Foreign Students in the United States
Get PDFMany language learners struggle with unequal access and lack of opportunities for active participation in meaningful discussions in and outside of the classroom. In this study, 15 international college students engaged in critical media literacy discussion over a myriad of social justice topics through the lens of intercultural understanding and acceptance. Participants analyzed the content and recorded video reflection on an online video discussion platform, Flipgrid as they answer the five critical media literacy questions. These critical questions foster discussions of intercultural interpretation online and in class discussions as students expressed their perceptions of social justice issues. This project drew on the theory of intercultural communicative competence (Byram, 1997) integrating social justice into language curriculum in two ways: by exposing students to important issues, and by helping students claim their voice in the discussion. Results of students’ video reflections and face-to-face discussions show the trajectory and growth of students’ progress in intercultural awareness. The findings offer guidelines for language educators to incorporate issues of social justice by using engaging platforms and media literacy practices
Boosting Vocabulary through the WordUp App
No full textVocabulary is an essential component in language learning. In addition to its relationship with other language skills, such as pronunciation (form), reading (meaning), and grammar (use), vocabulary is required for language proficiency. In parallel, language learners must be equipped with specific amounts of vocabulary to comprehend texts of diverse genres (e.g., novels, newspapers, and movies). However, learning vocabulary is incremental, and this skill challenges many language learners in their language-learning journeys for several reasons. Nevertheless, emerging mobile technologies might mitigate the negative impacts on language learning (e.g., lack of motivation and engaging learning environment). In this regard, the present study evaluates a mobile app called WordUp using Kohnke and Moorhouse's (2022) framework
Bilingual Viewer: A bilingual text generation tool
Get PDFThis article describes the website BilingualViewer.com; it discusses the technologies used to build it and the engineering challenges that were encountered. BilingualViewer.Com is an open and free application that uses web technologies to create Bilingual versions of articles and books. The website can be saved onto the homepage of a smartphone and used like an App (for reading and converting newspaper articles on the fly), in addition to being opened on a computer's browser to process intensive tasks such as whole book translations. The website will henceforth be referred to as the app. Bilingual text refers here to a piece of writing where sentences in two different languages are presented sequentially, one sentence in the language to be learned followed by the user's primary language. Bilingual texts are particularly useful for students who rely heavily on dictionaries when reading books and newspaper articles.The app helps to create bilingual texts from almost any electronic content.
A key feature from a copyright point of view is that the content is generated and stored locally on the device (unless added to an online library). Where a subscription is required to access newspaper content, the app generates a bilingual text article and stores it locally, so that the restricted content does not leave the device (i.e., it does not appear in any cloud server other than Google or Apple translation servers).
There is a large features list including switching on and off languages, getting the device to read out loud, saving a list of items on the device along with the currently read position, sending content to an eBook, merging articles and more. A library of pre-translated books is provided in the app with the option of augmenting this with the user’s own on-line content. The app is available at https://www.bilingualviewer.com/
Documentation on the app can be found at hhtps://bv-fc.netlify.app/about
Tectónica de efectos y afectos. Transparencia y desmaterialización de la envolvente arquitectónica
Get PDFThe article analyses, through drawing, projects and, in the realised cases, photographs that reflect how transparency and dematerialisation from expressionism and Glassarchitektur evolves with Mies van der Rohe and the heir architecture of transparency in SANAA with the aim of generating effects that transform the viewer’s perception, a trend that leads to media architectures such as Diller Scofidio + Renfro (DS+R). The tour demonstrates how a graphic and visual narrative develops that combines utopia and reality.En el artículo se analizan, a través del dibujo, proyectos y, en los casos realizados, fotografías que reflejan cómo la transparencia y la desmaterialización desde el expresionismo y la Glassarchitektur evoluciona con Mies van der Rohe y la heredera arquitectura de la transparencia de SANAA con el propósito de generar efectos que transforman la percepción del espectador, una tendencia que desemboca en arquitecturas mediáticas como la de Diller Scofidio + Renfro (DS+R). El recorrido demuestra cómo se desarrolla una narratividad gráfica y visual que compagina utopía y realidad
Le Corbusier. París, 1915. Construir dibujos, construir ciudades
Get PDFAfter writing the draft of La Construction des villes in 1910, this project was put on hold until 1915, when he moved to Paris for seven weeks. At the Bibliothéque Nationale he prepared a series of files with texts and sketches and, above all, devoted himself to copying new drawings. Now the workmanship is fast, and rather than faithfully reproducing, he interprets what he sees through a new prism: classicism. There are other references: Blondel and Laugier as sources of authority, but also books and plates by Piranesi, Perelle, Riat, Patte, oriental architecture, historical maps of Paris and prints and engravings from the Cabinet des Estampes. That book was definitively abandoned, but a new conception of the city began to take shape in those days and was reflected in his urban proposals and in Urbanisme, where he published some of these drawings.Tras la redacción del borrador de La Construction des villes en 1910, este proyecto fue relegado hasta 1915, cuando se trasladó a París durante siete semanas. En la Bibliothéque Nacional preparó una serie de fichas con textos y bocetos, y, sobre todo, se dedicó a copiar nuevos dibujos. Ahora la factura es rápida y más que reproducir fielmente interpreta lo que se ve bajo un nuevo prisma: el clasicismo. Son otros los referentes: Blondel y Laugier como fuentes de autoridad, también los libros y láminas de Piranesi, Perelle, Riat, Patte, la arquitectura oriental, las cartografías históricas de París y estampas y grabados procedentes del Cabinet des Estampes. Aquel libro fue definitivamente abandonado, pero una nueva concepción de la ciudad se comenzó a cimentar en aquellos días y vertida en sus propuestas urbanas y en Urbanisme, donde publicó alguno de estos dibujos
