La percusión corporal en la música tradicional y popular en España
No full textSince the dawn of time, human beings have expressed their musical essence using the elements
provided by nature. For this reason, the body, through the voice, hands and feet,
has been the first instrument used to produce sounds and rhythms, which is why body percussion
can be considered a primitive form of musical expression. Today, we can see
how it is used in various cultures and for specific purposes. In Spain, in particular, body percussion
represents a musical behaviour integrated into various choreographic expressions,
such as flamenco in Andalusia, the Ball dels moretons in Mallorca (Balearic Islands),
the Esku-dantza in the Basque Country or Las panaderas in Castile, and is used by
composers (not only Spanish) in the composition of music for bands.
Over the last two decades, the BAPNE Method has contributed significantly to the
study of body percussion through the production of an extensive scientific bibliography and
a pedagogical/didactic proposal developed from the contribution of five disciplines
(biomechanics, anatomy, psychology, neuroscience and ethnomusicology) with the aim of
demonstrating the benefits that its use can have in the development of executive and
cognitive functions.
Therefore, this doctoral thesis aims to demonstrate the hypotheses put forward by the BAPNE Method
through neuropsychological research in an Italian primary school, based
on the results obtained through an ethnomusicological, bibliographic and field study
carried out on body percussion in traditional and popular music in Spain.Desde sus orígenes, el ser humano ha manifestado su esencia musical utilizando los elementos

ha sido el primer instrumento útil para producir sonidos y ritmos, por lo que la percusión
corporal puede considerarse una forma primitiva de expresión musical. Hoy es posible observar
cómo se utiliza en varias culturas y con fines especificos. En España, en particular, la percusión
corporal representa un comportamiento musical integrado en diversas expresiones
coreográficas, como el flamenco en Andalucía, el Ball dels moretons en Mallorca (Islas
Baleares), la Esku-dantza en el País Vasco o Las panaderas en Castilla, y es utilizada por
autores (no solo españoles) en la composición de música para bandas.

From conventional to adapted microbiomes: Promoting high short-chain fatty acid yields and productivities from agricultural waste
No full textProducción CientíficaMicrobial consortia play an essential role in anaerobic fermentation (AF) devoted to the production of short-
chain fatty acids (SCFAs) from organic wastes. AF is usually performed by a conventional anaerobic micro-
biome (CM) sourced from anaerobic digestion reactors. During AF, the microbiome undergoes an adaptation
period to the imposed operational conditions and substrate characteristics, leading to the bio-enrichment of
certain microorganisms. This work compared the use of CM and a bio-enriched microbiome (BM) as inoculum for
AF of agricultural wastes in continuous stirred tank reactors (CSTR) with hydraulic retention time (HRT) of 8 d.
The novelty of this study lies in demonstrating that using a BM enhances the production rate of SCFAs when
compared to CM. BM, composed of adapted microorganisms previously working at an HRT of 10 d, allowed the
highest SCFAs productivity (1.97 g/L⋅d) and concentration (15.6 g/L). Bioconversion efficiencies achieved with
BM and CM (60.1 % and 71.8 %, respectively) were among the highest reported in literature. Microbiome
analysis revealed inoculum-driven changes in the microbial community. However, Clostridium and Megasphaera,
which are involved in the hydrolysis and acidification steps of AF and are associated with acetic acid formation
and chain elongation, predominated in all cases (up to 48 % of the microbial abundance within the total com-
munity). These results evidenced the feasibility of operating CSTRs at an HRT of 8 d with diverse inoculum
sources to maintain exceptionally high SCFA productivity and bioconversion. The outcomes also highlighted the
robustness of the microbial community, even under short HRT, providing a novel strategy for AF processes
optimization.Ministerio de Economía y Competitividad (grand RYC2019-027773-I)Ministerio de Ciencia e Innovación (contrato predoctoral para la formación de futuros doctores (FPI 2021) - (PID2020-119403RB-C21)

Non-invasive electroluminescence and photoluminescence imaging through module-level electronics in photovoltaic power plants
No full textPhotovoltaic technology has experienced a rapid increase in global capacity in recent years, becoming one of the renewable technologies with the highest growth potential. Proper maintenance and operation of PV power plants require module inspection techniques to detect faults and analyse degradation, which could reduce power output or pose safety risks. Among the most common inspection methods for field-deployed modules are current–voltage curve tracing, infrared thermography, and luminescence imaging. Luminescence imaging (electroluminescence and photoluminescence) is particularly valuable, as it reveals the inner structure of solar cells, enabling fault detection and performance analysis, although its integration in PV plants is limited by practical constraints.
Conventional luminescence imaging relies on EL signal acquisition in dark conditions, requiring module disconnection, external power supplies, and nighttime measurements. These requirements make it invasive, time-consuming, and logistically complex, unsuitable for inspecting thousands of modules. Novel approaches overcome these limitations by enabling measurements under daylight without disconnection, typically through modulation of electroluminescence or photoluminescence signals and post-processing to remove sunlight signal. This thesis explores a technique based on module-level electronic devices to enhance signal modulation.
For this purpose, an electronic architecture has been designed and validated, enabling the modulation of both electroluminescence and photoluminescence signals. By installing this device in each module where modulation is required, non-invasive electroluminescence and photoluminescence imaging can be achieved. Moreover, these measurements do not require external energy sources such as power supplies, and image acquisition can be performed during daytime while the photovoltaic power plant operates under normal conditions.
In addition, different approaches for processing image sequences acquired during luminescence signal modulation have been explored. First, time-domain processing has been studied using two strategies: a synchronous strategy, which requires continuous communication between the electronic device that modulates the signal and the camera that captures the images, allowing direct labelling of each picture according to its emission state; and an asynchronous strategy, which does not require continuous communication but instead relies on an algorithm to automatically classify the images. Secondly, frequency-domain processing based on the Fast Fourier Transform has been successfully validated, enabling background removal when the luminescence signal is modulated using any periodic waveform.
Finally, photoluminescence signal modulation has been integrated into the topology of a module-level PV optimizer. In addition, current–voltage curve tracing has also been incorporated. Taken together, a module-level electronic device with extended functionalities and only minor hardware modifications has been developed and validated. The device integrates maximum power point tracking alongside non-invasive photoluminescence modulation and non-invasive current-voltage curve tracing, two inspection techniques that are conventionally invasive.La tecnología fotovoltaica ha experimentado un rápido aumento de capacidad mundial en los últimos años, convirtiéndose en una de las energías renovables con mayor potencial de crecimiento. El mantenimiento y operación de las plantas fotovoltaicas requieren técnicas de inspección para detectar fallos y analizar degradación, que pueden reducir la producción de energía o generar riesgos de seguridad. Entre los métodos más comunes para módulos en campo están el trazado de curvas de corriente y tensión, la termografía infrarroja y las imágenes de luminiscencia. Las imágenes de luminiscencia (electroluminiscencia y fotoluminiscencia) son valiosas, pues revelan la estructura interna de las células solares, permitiendo detectar fallos y analizar rendimiento, aunque su integración en plantas fotovoltaicas sigue limitada por restricciones prácticas.
Las imágenes de luminiscencia convencional se basan en la adquisición de la señal de electroluminiscencia en condiciones de oscuridad, requiriendo la desconexión de módulos, fuentes de alimentación externas y mediciones nocturnas. Estos requisitos hacen que el método sea invasivo, lento y logísticamente complejo, inadecuado para inspeccionar los miles de módulos de una planta moderna. Los enfoques novedosos superan estas limitaciones al permitir mediciones diurnas sin desconexión, generalmente mediante la modulación de señales de luminiscencia y un procesamiento posterior para eliminar la señal solar. La presente tesis explora una técnica basada en dispositivos electrónicos a nivel de módulo para lograr dicha modulación.
Para ello, se ha diseñado y validado una arquitectura electrónica que permite la modulación de señales tanto de electroluminiscencia como de fotoluminiscencia. La instalación de este dispositivo en cada módulo permite realizar imágenes de electroluminiscencia y fotoluminiscencia de manera no invasiva. Además, estas mediciones no requieren fuentes de energía externas y las medidas pueden realizarse durante el día mientras la planta fotovoltaica opera en condiciones normales.
Asimismo, se han explorado diferentes estrategias para procesar las secuencias de imágenes obtenidas durante la modulación de la señal de luminiscencia. Primero, se ha estudiado el procesamiento en el dominio del tiempo con dos enfoques: una estrategia síncrona, que requiere comunicación continua entre el dispositivo que modula la señal y la cámara, permitiendo etiquetar cada imagen según su estado de emisión; y una estrategia asíncrona, que no requiere comunicación continua y se basa en un algoritmo para clasificar automáticamente las imágenes. En segundo lugar, se ha validado con éxito el procesamiento en el dominio de la frecuencia, basado en la transformada rápida de Fourier, que permite eliminar la señal de fondo cuando la luminiscencia se modula con cualquier forma de onda periódica.
Finalmente, la modulación de la señal de fotoluminiscencia se ha integrado en la topología de un optimizador fotovoltaico a nivel de módulo. Además, también se ha incorporado el trazado de curvas de corriente y tensión. En conjunto, se ha desarrollado y validado un dispositivo electrónico a nivel de módulo con funcionalidades ampliadas y modificaciones de hardware mínimas. Este dispositivo integra el seguimiento del punto de máxima potencia junto con la modulación de fotoluminiscencia y el trazado de curvas de corriente y tensión de manera no invasiva, dos técnicas de inspección que convencionalmente son invasivas.Escuela de DoctoradoDoctorado en Ingeniería Industria
Terminología y traducción (ES>EN) del vinagre de vino
No full textThe wine and vine language constitutes a specialized language nourished by texts from the wine sector, and these texts need a specific analysis. While wine has been widely studied from linguistic and translation perspectives, wine vinegar has received little attention beyond chemical and oenological fields. This study addresses this gap with two objectives: (1) to determine whether the limited research is linked to the negative connotation associated with vinegar and (2) to describe the fact sheet and its lexical units. To this end, the representation of vinegar was analyzed in specialized discourse —treatises— and in texts aimed at heterogeneous audiences —fact sheets—, assessing whether negative perceptions influence these texts.
The research is grounded in corpus linguistics through two resources: the GIRTraduvino macrocorpus “ENOCORP,” which contains texts representing this specialized language, and “AcetiCorpus,” composed of fact sheets split into a parallel corpus (vinegars with and without PDO) and a comparable corpus (U.S. products). The former enabled a diachronic and contrastive analysis of vinegar definitions; the latter was used to categorize the fact sheet, the tasting phase, and specialized lexical units. Given the sector's cultural and export relevance, these corpora also served to evaluate linguistic transfer.
Results confirm that vinegar-related texts are shorter, less persuasive, and less descriptive than wine texts. Nevertheless, a broad lexical repertoire was systematized in Spanish and U.S. English, mainly originating from tasting —especially the olfactory phase—. These units, derived from general language, acquire specialized nuances, which makes them relatively transparent for native speakers but poses challenges in translation due to cultural differences in production and characterization. U.S. descriptors were more specific, and issues were detected in transferring Spanish culturemes. The study examined how wineries and various machine translation systems, including AI, manage this transfer, concluding that AI, when oriented toward lay audiences, produces more adapted texts than MT systems and official winery translations.
As an applicable outcome for the wine sector, a multimodal tool —the wine vinegar aroma wheel— was designed for olfactory evaluations, sensory learning, wine tourism, and gastronomy. This research highlights the need to consolidate a new branch within the language of vine and wine, with future projects ensuring its continuity and applicability for companies, regulatory councils, and individual users.La lengua vinculada a la vid y el vino constituye una lengua de especialidad que se compone de los textos del sector vitivinícola y esto requiere el análisis de todos ellos. Mientras el vino ha sido ampliamente estudiado desde perspectivas lingüísticas y traductológicas, el vinagre de vino apenas ha recibido atención fuera de ámbitos químicos y enológicos. Este estudio aborda dicha carencia con un doble objetivo: (1) indagar si la escasa investigación responde a la connotación negativa asociada al vinagre y (2) describir la ficha técnica y las unidades léxicas que la conforman. Para ello, se analizó la representación del vinagre en discursos especializados —tratados— y en textos dirigidos a públicos heterogéneos —fichas técnicas—, evaluando si la percepción negativa condiciona los textos.
La investigación se sustenta en la lingüística de corpus mediante dos recursos: el macrocorpus de GIRTraduvino “ENOCORP”, que contiene textos sobre dicha lengua de especialidad, y “AcetiCorpus”, compuesto por fichas técnicas estratificadas en corpus paralelo (vinagres con y sin D. O. P.) y comparable (productos estadounidenses). El primero permitió analizar diacrónica y contrastivamente la definición del vinagre; el segundo, la categorización de la ficha técnica, la fase de cata y las unidades léxicas especializadas incluidas en estos documentos. Dada la relevancia cultural y exportadora del sector, estos corpus también sirvieron para evaluar la transferencia lingüística.
Los resultados confirman que los textos sobre vinagre son más breves, menos persuasivos y con menor carga descriptiva que los del vino. No obstante, se sistematizó un amplio repertorio léxico en español e inglés estadounidense, principalmente procedente de la cata —sobre todo, la fase olfativa—. Estas unidades, originadas en la lengua general, adquieren un valor especializado, lo que facilita su comprensión para hablantes nativos, aunque plantea dificultades en traducción por divergencias culturales en producción y caracterización. Se detectaron descriptores más concretos en textos estadounidenses y problemas en la transferencia de culturemas españoles. El estudio analizó cómo las bodegas y diversos sistemas de traducción automática e inteligencia artificial gestionan este trasvase, concluyendo que las IA, cuando se orientan a receptores legos, generan textos más adaptados que las TAN y traducciones oficiales.
Como resultado aplicable para el sector vitivinícola, se diseñó una herramienta multimodal —la rueda de aromas— para evaluaciones olfativas, aprendizaje sensorial, enoturismo y gastronomía. Esta investigación evidencia la necesidad de consolidar una nueva línea dentro de la lengua de la vid y el vino, con proyección hacia futuros proyectos que garanticen su continuidad y aplicabilidad en empresas, consejos reguladores y usuarios particulares.Escuela de DoctoradoDoctorado en Traductología, Traducción Profesional y Audiovisua
Attitudes in didactic change: design and validation of a questionnaire of Primary Education teachers’ attitudes toward the teaching of the Nature of Science and Technology
No full textProducción CientíficaIntroduction: Neglecting the role of attitudes in didactic change is a serious obstacle to progressing toward the inclusion of the Nature of Science and Technology (NoST) in the classroom and achieving a scientific culture that enables the development of a critical and socially engaged citizenship capable of addressing contemporary societal challenges.
Method: For this reason, this study presents the design and validation of an assessment tool that allows attitudes to be collected in a holistic way, taking into account the cognitive, affective and conative components of trainee and practicing Primary School (PS) teachers toward the teaching of NoST. For this purpose, an instrumental-psychometric study was carried out. A sample of 210 subjects participated in the validation of the questionnaire.
Results: The statistical analyses of the scale show that it has an adequate content validity, an appropriate construct validity with a good fit to the theoretical model, and a high level of reliability. Furthermore, a first approximation to the description of the attitudinal profile indicates that thereis, in general, a positive attitude toward NoST teaching.
Discussion: It is concluded, on the one hand, that the instrument is optimal and adequate for assessing attitudes and, on the other hand, that teacher training should consider both the cognitive and affective factors that hinder the transformation of educational practices in the field of science teaching.This research was funded by the Ministry of Education and Vocational Training of the Government of Spain through a grant contract for University Teacher Training (FPU 21/04817)

The miniversal deformation of certain complete intersection monomial curves
No full textProducción CientíficaThe aim of this paper is to provide an explicit basis of the miniversal deformation of a monomial curve defined by a free semigroup—these curves make up a notable family
of complete intersection monomial curves. First, we dispense a general decomposition result of a basis B of the miniversal deformation of any complete intersection monomial curve. As a consequence, we explicitly calculate B in the particular case of a monomial curve defined from a free semigroup.

Hate Speech on Social Media: Unpacking How Toxic Language Fuels Anti-Immigrant Hostility
No full textProducción CientíficaThis study investigates the influence of toxic language in hate speech targeting immigrants, particularly through narrative formats like first-person X (Twitter) threads. Hate speech, defined as promotion of hatred based on personal or group characteristics, increasingly escalates
on social media, impacting public attitudes and behaviors. While previous research
has primarily focused on measuring the scope of hate speech through content analysis and computational methods, there has been limited attention to its effects on audiences.
This study presents the results of an online experiment (N = 339) with a 2 × 2 between subjects design that manipulates the presence of toxic language and message popularity.
Results indicate that hate messages lacking toxic language promote greater identity fusion with the author of the message, which in turn increases the intention to share the message,
reinforces negative attitudes toward immigrants, and increases support for harsh policies against irregular immigration. Moreover, non-toxic hate messages significantly enhance narrative transportation exclusively for individuals with conservative political views, thereby further increasing their intention to share the message. These findings highlight that subtler forms of hate speech can create strong audience connections with
hostile perspectives, emphasizing the need for anti-hate campaigns to address both overt and subtle hate content
Cost-benefit analysis of the nesting approach in HARMONIE-AROME for a supercell outbreak case study
No full textSupercells are among the most hazardous convective systems, frequently producing large hail, destructive winds,
and severe socio-economic impacts. The enhancement of weather simulations is identified as a primary strategy
to optimise short-term forecasting. The present study investigates the performance of two high-resolution con-
figurations of the HARMONIE-AROME model during a severe supercell outbreak over eastern Iberia on 31st July
2015, when six confirmed supercells caused significant damage. The setups tested include a two-step one-way
nested approach (2.5 km outer domain and 500 m inner domain), and a single-domain configuration at 500 m
resolution. The model outputs, which include reflectivity, precipitation and temperature, are validated against
OPERA radar composites and surface observations. At the same time, key convective parameters, derived from
the Murcia sounding, are analyzed to assess the pre-convective environment. Although the simulations
demonstrate a similar structure to the observed event, the two-domain nested simulation offers a slightly su-
perior depiction of reflectivity and thermodynamic profiles. Nevertheless, precipitation analysis reveals that
while nesting improves moderate rainfall representation, it introduces larger errors for the most extreme
amounts, limiting its overall benefit. The obtained gain is not sufficient to offset the 30% higher computational
cost when the two-domain nested approach is used. The single-domain non-nested configuration demonstrates a
superior level of efficiency, exhibiting equivalent accuracy while exhibiting a diminished resource requirement.Ministerio de Ciencia, Innovación y Universidades (MICIU), AEI/10.13039/501100011033/FEDER y UE (grant PID2023-146344OB-I00
