Item type: Artículo , Access status: Cerrado , El Juego del "Boliche" de la Aldea de Estenas (Utiel). La despoblación en la Comunidad Valenciana(Casa de Cultura de Utiel, 2024) Furió Orba, María Dolores[ES] La despoblación constituye un problema importante en numerosas regiones de España, incluida la Comunidad Valenciana. La despoblación también está relacionada con la pérdida de la cultura en la educación y los juegos tradicionales, lo que amplifica el impacto negativo en la sociedad y la identidad cultural de las áreas rurales.Item type: Artículo , Access status: Abierto , Integrating blue foods into food system approaches and frameworks(IOP Publishing, 2026-06-01) Smith, Hillary; Advani, Sahir; Suri, Sharon K.; Amadu, Iddrisu; Ahern, Molly; Obregon Lafuente, Clara; Kriegl, Michael; Standen, Sophie; Giordano, Chris; Partelow, Stefan[EN] Despite supplying essential nutrients to billions of people and sustaining hundreds of millions of livelihoods, blue foods are overlooked within food system frameworks and debates. This Perspective highlights the shortcomings and potential of the High-Level Panel Of Experts (HLPE) sustainable food systems (SFS) framework in addressing blue food dynamics. Drawing on a review of 124 peer-reviewed articles that cite the HLPE framework, and an examination of its authorship and values, we demonstrate that blue foods are rarely integrated into food systems analyses, reflecting epistemic inequalities in the field. We identify critical omissions-including production dynamics, food loss and waste, consolidation in supply chains, and normative values shaping decision-making-that constrain the framework's application to blue foods (and other diverse contexts). To advance more inclusive and effective food system approaches, we recommend (1) greater use of food systems frameworks to examine blue food dynamics and other diverse food systems contexts, (2) updates to the SFS framework to integrate blue food contexts, and (3) guidance to operationalize these frameworks for research and policy action. We call on the HLPE to update the SFS framework, particularly through the forthcoming (2027) report on fisheries and aquaculture, to spotlight the framework's utility for capturing the complexity of diverse yet essential food systems beyond production, including aquatic food systems.Item type: Artículo , Access status: Cerrado , Las disposiciones adicionales de la Ley 3/2025, de 22 de mayo, de Protección y Ordenación de la Costa Valenciana(La Ley, 2025) Hervás Más, Jorge[ES] La invocación del derecho comparado con otras Comunidades Autónomas en la elaboración de leyes se ha convertido, con demasiada frecuencia, en una coartada intelectual para justificar decisiones legislativas ya preconcebidas. Se presenta el derecho comparado como un ejercicio de erudición, cuando en realidad suele reducirse a copiar mecánicamente modelos foráneos sin considerar su razón de ser, legitimidad ni aplicabilidad. Todo sirve, siempre que respalde lo que ya se quería hacer desde el minuto cero. La Ley 3/2025, de 22 de mayo, de Protección y Ordenación de la Costa Valenciana (en adelante, LPOCV) es una muestra clara y evidente de esta técnica; una norma que carece por completo de originalidad y autenticidad y que replica y copia el contenido de otras disposiciones normativas, concretamente la Ley 4/2023, de 6 de julio, de Ordenación y Gestión Integrada del Litoral de GaliciaItem type: Artículo , Access status: Abierto , Laboratory-scale setup for radon transport monitoring in radionuclide-rich soils: Key points identification and protocols development(Elsevier, 2026-09) Trull-Hernandis, Cristina; Moreno-Ramón, Héctor; Sancho, M.; Lidón, Antonio; Juste-Vidal, Belen-Jeanne; UNIVERSIDAD POLITECNICA DE VALENCIA[EN] A laboratory-scale experimental setup has been developed to simulate radon transport from radionuclide-rich soils under dynamic conditions. The setup allows simultaneous monitoring of the mobility of radon gas by leaching and by exhaling into the air phase under varying soil moisture conditions. Given that radon is a radioactive gas classified as Group 1 human carcinogen and stands as the 2nd reason for lung cancer worldwide, understanding its release and transport mechanisms in any environment is essential for effective radiological risk assessment. This work highlights the key aspects that must be considered and controlled to ensure a reproducible and stable experimental design that emulates the configuration of scenarios such as phosphate waste ponds and zones where radioactive content is distributed throughout the terrain. The identification of critical operational parameters provides a robust framework on what to consider when addressing the radon transport characterization and, later, be able to investigate the influence that environmental and the soil conditions have over radon release mechanisms.Item type: Artículo , Access status: Abierto , Multiscale Experimental Framework for the Characterization of Unstabilized Rammed Earth(MDPI AG, 2026-06-15) Ávila, Fernando; Fagone, Mario; Puertas, Esther; Ranocchiai, Giovanna[EN] The mechanical response of unstabilized rammed earth (URE) depends on a chain of factors spanning from soil composition to compaction conditions and specimen geometry and manufacturing conditions. This paper proposes a multiscale experimental framework for the physical and mechanical characterization of URE, structured around three hierarchical scales¿soil, fabric and specimen¿and demonstrates it on a single soil sample used consistently across more than a decade of experimental campaigns. At the soil scale, mineralogical composition, particle size distribution, Atterberg limits and linear shrinkage are determined. At the fabric scale, Proctor compaction tests establish the optimum moisture content and maximum dry density, and cohesion tests quantify the tensile cohesion of the material. At the specimen scale, monotonic and cyclic uniaxial compression tests reveal that compressive strength is essentially isotropic with respect to loading direction, while stiffness exhibits a pronounced anisotropy, with an anisotropy coefficient of 2.6. A Proctor-based specimen manufacturing procedure is used to reduce the coefficient of variation of compressive strength from 11.8% to 1.8%, demonstrating the critical role of compaction control in result reproducibility. Diagonal compression tests yield a shear strength of approximately 10% of the compressive strength, consistent with the tensile-to-compressive strength ratio commonly reported for URE. The proposed framework highlights the limitations of single-parameter characterization and provides methodological guidance applicable from soil evaluation to full mechanical characterization of URE.Item type: Artículo , Access status: Cerrado , Inteligencia artificial para la generación de sinopsis en seminarios especializados(Sociedad Española de Química Analítica, 2025-12) Tortajada-Genaro, Luis Antonio[ES] La Inteligencia Artificial (IA) está transformando el panorama educativo, ofreciendo nuevas posibilidades y enriqueciendo la experiencia de aprendizaje. Esta investigación se centró en la integración de la IA en los seminarios docentes, especialmente en el proceso de análisis y generación de conclusiones. Tras sesiones de exposiciones, se generaron resúmenes y esquemas conceptuales que agruparon los principales resultados obtenidos. El uso de la IA redujo significativamente el tiempo de sinopsis y redacción, mejorando la precisión, atractivo visual y coherencia frente a los procesos tradicionales. Esto aceleró el desarrollo de capacidades de análisis, identificación de patrones y retroalimentación, abriendo nuevas vías para abordar la diversidad en el aula y fomentar la motivación. La actividad fue muy bien recibida por el alumnado, que mostró una actitud participativa y valoró positivamente su carácter innovador y colaborativo. Las implicaciones de esta investigación son extrapolables a entornos de formación continua y educación superior.Item type: Artículo , Access status: Cerrado , Beslenmek bizi insan yapti(Ulusal Strateji Merkezi Egitim Arastirma Danismanlik Yayincilik ve Ticatet Limited Sirketi, 2025) Mulet, José Miguel[ES] Es evidente que los seres humanos, como organismos vivos, son el resultado de millones de años de evolución, y que lo que comemos (y, por supuesto, la levadura) ha moldeado esa evolución. Sin embargo, hay otro aspecto más. ¿Por qué el Homo sapiens ocupa la cima de la cadena alimentaria o se considera (con el permiso de la levadura) el rey de la evolución? ¿Tiene esto alguna relación con lo que comemos o con la forma en que comemos?Item type: Artículo , Access status: Cerrado , Visión artificial para la identificación en tiempo real del comportamiento en cabras(Grupo de Comunicación AgriNews, 2025) Méndez-Reyes, Daniel Alexander; Fajardo-Viloria, Blanca; Gil-Vidal, Eliseo; Calvet, S.; Costantino, Andrea; Agencia Estatal de Investigación; UNIVERSIDAD POLITECNICA DE VALENCIA[ES] El comportamiento es clave para evaluar el bienestar y salud de las cabras, puesto que detectar cambios tempranos en sus patrones de actividad permite anticipar posibles problemas sanitarios.Item type: Artículo , Access status: Cerrado , Strategic-Financial Alignment in the Mining Industry Through Data-Driven Management(Universidad Tecnológica Atlántico Mediterráneo (UTAMED), 2025-12) García-Hurtado, Dayanis; Alarcón-Armenteros, Adelfa; Arocha-Hernández, Tania[EN] In a context of uncertainty and complexity, Peruvian organizations face the challenge of achieving strategic alignment that guarantees their competitive positioning. This environment demands data-driven management, where informed decision-making is the engine that propels institutional performance. The objective of this study is to evaluate the degree of coherence between financial processes and strategic objectives in a Peruvian mining company (Andina) using a data-driven management approach. A qualitative, single-case methodology with a multimethod approach was employed, integrating semistructured interviews with experts and the application of impact and alignment matrices. The quantitative results reveal a strategic alignment index (SAI) of 9.42, indicating ¿high alignment¿ in structural terms. Results indicate a high level of alignment, suggesting coherent integration of financial planning, risk management, operational efficiency, and sustainability objectives. The findings underscore the importance of information-based management and technological tools, such as digital control systems, automated processes, and strategic dashboards, in enhancing decision-making, improving performance, and fostering innovation within the mining sector.Item type: Artículo , Access status: Abierto , Physicochemical properties of La0.5Ba0.5Co1-xFexO3-o (0 <= x <= 1) as positrode for proton ceramic electrochemical cells(Elsevier, 2025-01-01) Wachowski, Sebastian L.; Szpunar, Iga; Pospiech, Joanna; Balcerzak, Daria; Mielewczyk-Gryn, Aleksandra; Nadolska, Malgorzata; Balaguer Ramirez, Maria; Serra Alfaro, José Manuel; Vollestad, Einar; Gazda, Maria; Strandbakke, Ragnar; Norby, Truls; European Commission; Research Council of Norway; Agencia Estatal de Investigación; Consejo Superior de Investigaciones Científicas[EN] We report on essential properties of materials in the series La0.5Ba0.5Co1-xFexO3-delta as positrodes for proton ceramic electrochemical cells (PCECs). The unit cell and thermochemical expansion coefficient (TCEC) of these cubic perovskites decrease with iron content x, the TCEC of La0.5Ba0.5FeO3-delta going as low as 1110(-6) 1/K. The materials behave as LaMO3 perovskites with small band gaps and Ba acting as acceptors compensated by electron holes and oxygen vacancies. The electrical properties are dominated by p-type conduction with high large polaron mobilities for the Co-rich compositions at low temperatures, shifting towards small polaron mobilities with increasing Fe content. X-ray absorption spectroscopy (XAS) shows that Co is in a high spin state and takes on the main part of the cation oxidation state changes, and that hole states are in orbitals overlapping with the O 2p states, confirming the large polaronic behaviour, while holes on Fe are more localised at the cation. Hydration is more pronounced in inert atmospheres, as hydration of oxygen vacancies is easier than hydrogenation and increases with Fe content, in line with the commonly accepted finding that delocalization of holes disfavours protonation. Fe-rich compositions benefit from lower TCEC and higher hydration and hence expected proton permeability, at the cost of lower electronic conductivity. The surfaces are hydrophobic irrespective of Fe content, suggesting weak chemisorption of the underlaying water layer, possibly giving relatively many available surface sites for oxygen adsorption, but limited surface proton conductance - both of importance to positrodes for operando PCECs.Item type: Artículo , Access status: Abierto , Sim-Exact Methods for Stochastic Optimization: A Complementary Approach to Simheuristics(MDPI AG, 2026-04-30) Juan, Angel A.; Rodríguez Uguina, Antonio; Escoto-Gomar, Marc; Medina-Rodriguez, Veronica; Generalitat Valenciana; Agencia Estatal de Investigación[EN] This paper introduces a sim-exact methodology for stochastic combinatorial optimization problems. The approach combines exact optimization models with Monte Carlo or discrete-event simulation to evaluate candidate solutions under uncertainty. The method iteratively adjusts a control parameter based on simulation feedback and solves a sequence of deterministic optimization problems. Unlike scenario-based stochastic programming, the approach does not rely on explicit scenario enumeration, and unlike simheuristics, it preserves optimality with respect to each deterministic subproblem. The methodology is tested on the vehicle routing problem with stochastic demands under different levels of demand variability. Results are compared with a simheuristic approach and a sample average approximation (SAA) method. The results show that sim-exact performance is comparable to simheuristics, with no statistically significant differences in most cases, while SAA shows weaker performance under medium and high variability.Item type: Artículo , Access status: Abierto , Targeting ParPMC Susceptibility Hubs in Prunus: eEF1A as a Conserved Mediator of Plum Pox Virus Infection in Nicotiana benthamiana(Blackwell Publishing, 2026-05-21) Polo-Oltra, Angela; Lloret-Compañ, Alba; Sánchez-Navarro, Jesús-Ángel; Rios, Gabino; Romero Salvador, Carlos; Zuriaga, Elena; Generalitat Valenciana; Agencia Estatal de Investigación; European Regional Development Fund[EN] Sharka, caused by Potyvirus plumpoxi (plum pox virus, PPV), is the most destructive viral disease affecting Prunus species worldwide. Two MATH domain-containing genes, ParPMC1 and ParPMC2, have been identified in apricot as host susceptibility factors required for PPV infection, but their molecular function remains unclear. Here, we investigated ParPMC functions by identifying their interacting partners and assessing their contribution to viral replication and movement. Yeast two-hybrid screening of PPV-infected apricot tissues revealed 13 ParPMC interactors involved in defence and stress responses, primary metabolism, protein folding and gene expression. Among them, two eukaryotic elongation factor 1-alpha proteins (eEF1A; Pruar1 and Pruar9) were selected for further analysis. In planta assays showed that both ParPMC proteins colocalize with eEF1A at endoplasmic reticulum-derived perinuclear structures associated with viral replication complexes; however, a specific physical interaction was detected only for ParPMC1, suggesting paralog specialisation. Phylogenetic analyses revealed independent diversification of eEF1A gene families in Rosaceae and Solanaceae. Despite the lack of strict orthology, silencing clade B eEF1A isoforms in Nicotiana benthamiana using a cucumber mosaic virus-based virus-induced gene silencing system strongly reduced PPV accumulation and systemic spread, highlighting a conserved proviral role. These results support a model in which ParPMC1 facilitates PPV infection by recruiting or stabilising eEF1A at viral replication sites, whereas ParPMC2 may contribute through alternative interactors. This study advances our understanding of ParPMC-mediated PPV-susceptibility in apricot and highlights host-virus interactions with potential relevance for resistance strategies in Prunus and other potyvirus-susceptible crops.Item type: Artículo , Access status: Cerrado , Aplicación de jugo de caqui como colorante natural sobre tejidos de algodón y seda(Asociación Española de Químicos y Coloristas Textiles, 2025) Herráez Aparicio, Víctor; Sirvent Segura, Elia Ana; Blanes-Company, María; Bou-Belda, Eva[ES] Actualmente, la mayor parte de la industria textil utiliza colorantes sintéticos que no son biodegradables y, en algunos casos, presentan una alta toxicidad. Por ello, existe un gran interés en reconsiderar las técnicas tradicionales de tintura y explorar opciones naturales para la coloración de textiles. Este proyecto se centra en la tintura de fibras naturales con zumo de caqui, un método artesanal que se utilizaba antes de la industrialización del sector textil. A través de procesos industriales convencionales, se evaluará la viabilidad de aplicar este colorante mediante técnicas de tintura en continuo y por agotamiento sobre tejido de algodón y seda. Se evaluará el color obtenido mediante espectrofotómetro de reflexión y se llevarán a cabo diversos ensayos para determinar la calidad de la tintura. El objetivo final es ofrecer a la industria textil moderna una alternativa natural a los colorantes sintéticos.Item type: Artículo , Access status: Cerrado , Estimación de la condición del pavimento a partir de datos de vehículos autónomos y conectados(Prensa Técnica, 2025) Llopis-Castelló, David; Camacho-Torregrosa, Francisco Javier; Romeral Pérez, Fabio; Valdecantos Álvarez, José Carlos; Tomás Martínez, Pedro[EN] Proper maintenance of the road network is crucial to preserving and improving citizens¿ quality of life. Otherwise, the costs associated with the transportation of goods and people would increase, since poor road conditions are linked to a higher risk of accidents, greater fuel consumption, and consequently, an increase in greenhouse gas emissions.Current methods for assessing pavement conditions on roads involve carrying out inspections with specialized equipment to evaluate both the state of the surface and driving quality or comfort. This means that the administration cannot inspect the entire road network annually due to technical and economic limitations. In this context, crowdsourcing data from connected and autonomous vehicles (CAVs) with enhanced attributes emerges as an alternative to the use of instrumented equipment. Unlike traditional inspection methods¿whose results largely depend on the specific track followed by the specialized equipment at the time of measurement and whose data collection frequency is very limited¿the use of data from CAVs provides more reliable, near real-time information on road conditions, since each point of the roadway can be monitored by hundreds or thousands of vehicles.Therefore, the main objective of this work is to evaluate the feasibility of using CAV data to assess pavement conditions through the International Roughness Index (IRI). To this end, CAV-derived data have been compared with traditional inspection data, establishing different thresholds to quantitatively and qualitatively define pavement condition based on vehicle data.Item type: Artículo , Access status: Abierto , Built Environment, Social Integration, and Well-Being Among Older Adults in NORCs: A Cross-Sectional Study in New York(MDPI, 2026-02-22) García-Sánchez, Ana María; Torres Barchino, Ana María; Llopis Verdú, Jorge; Universitat Politècnica de València[EN] Naturally Occurring Retirement Communities Supportive Service Programs (NORC-SSPs) are one of the most popular models of aging in place. While the existing NORC literature focuses on the social and service environments of these programs, their built environments remain underexplored, particularly across housing tenures. This study is the first to explore the built environment, social integration, and socio-demographic factors among older people living in NORCs in New York, and their associations with health and well-being. The mixed-methods research included qualitative (interviews with NORC directors) and quantitative (151 resident surveys and an architectural assessment) data on 26 housing developments in New York, collected simultaneously using a convergent parallel design. The findings show that socialization and exercise improve the health and quality of life of NORC residents. The study also revealed that older people living in public housing have different needs than those in cooperative housing, namely a worse perception of their health and dwellings of a poorer physical condition. Therefore, the services offered by NORC programs should vary according to housing type, while management and NORC staff should improve coordination to address maintenance in public housing. Future research should examine interventions to improve the physical environments of NORC residents.Item type: Artículo , Access status: Embargado , Opening the black box of loss on ignition of agricultural-based ashes as SCM: Carbon type characterization and its effect on cement hydration and rheology(Elsevier, 2026-08) Vieira, Amanda Pereira; Tavares, Luis Marcelo; Paya Bernabeu, Jorge Juan; Filho, Romildo Dias Toledo; Coordenaçao de Aperfeiçoamento de Pessoal de Nível Superior, Brasil[EN] Despite decades of research on rice husk ash (RHA) and sugarcane bagasse ash (SCBA) as pozzolanic materials, no study has systematically addressed the nature of residual carbon in these ashes. Several standards limit the loss on ignition (LOI) of pozzolans to <= 6%, a criterion that excludes many residual RHAs and SCBAs from potential use. This study demonstrates that LOI is neither a reliable indicator of the actual carbon content nor of its influence on cement hydration. A comprehensive characterization combining FTIR, Raman spectroscopy, and thermogravimetric analysis coupled with mass spectrometry identified three distinct forms of residual carbon: volatile organic fraction (VOF), amorphous carbon, and graphitized carbon. Amorphous carbon, the dominant carbon fraction in agro-industrial ashes, was associated with hydration acceleration, whereas graphitized carbon showed a negligible influence on hydration. In contrast, VOF, composed primarily of residual lignin and cellulose, was identified as the key factor responsible for hydration retardation and rheological modification. The presence of hydroxyl and carboxyl functional groups, analogous to those found in lignin/cellulose-based dispersants, explains the delayed hydration kinetics and the improved paste workability. This important identification of amorphous carbon was only possible through the use of chemical methods, which can discriminate reactive amorphous silica from alumina, which contrasts from Rietveld-based amorphous phase quantification, where amorphous carbon and vitreous inorganic phases are incorporated into the total amorphous fraction estimated. Multiple linear regression analysis confirmed the statistically significant influence of volatile organic fraction and specific surface area on both hydration kinetics and rheological parameters, revealing antagonistic effects whose combinations lead to distinct behaviors.Item type: Artículo , Access status: Abierto , Advanced Insurance Risk Modeling for Pseudo-New Customers Using Balanced Ensembles and Transfomer Architectures(MDPI, 2026-04-17) Solly, Finn L.; Soriano-González, Raquel; Juan, Angel A.; Guerrero, Antoni; GENERALITAT VALENCIANA; AGENCIA ESTATAL DE INVESTIGACION; Agencia Estatal de Investigación[EN] In insurance portfolios, classifying customers without a prior history at a given company is particularly challenging due to the absence of historical behavior, extreme class imbalance, heavy-tailed loss distributions, and strict operational constraints. Traditional machine learning approaches, including the baseline methodology proposed in previous studies, typically optimize global predictive accuracy and therefore fail to capture business-critical outcomes, especially the identification of high-risk clients. This study extends the existing approach by evaluating two complementary business-aware classification strategies: (i) a balanced bagging ensemble specifically designed to handle class imbalance and maximize expected profit under explicit customer-omission constraints, and (ii) a lightweight Transformer-based architecture capable of learning richer feature representations. Both approaches incorporate the asymmetric financial cost structure of insurance and operate under operational selection limits. The empirical analysis is conducted on a proprietary large-scale auto insurance dataset comprising 51,618 customers and is complemented by validation on nine synthetic datasets to assess robustness. Model performance is evaluated using statistical tests (ANOVA, Friedman, and pair-wise comparisons) together with business-oriented metrics. The results show that both proposed approaches consistently outperform the baseline methodology (p < 0.001) in terms of profit, with the ensemble offering a better balance of performance and efficiency, while the Transformer shows stronger robustness and generalization under data perturbations. The balanced ensemble provides the most favourable trade-off between predictive performance, robustness, interpretability, and computational efficiency, making it suitable for deployment in regulated insurance environments, while the Transformer achieves competitive results and exhibits stronger generalization under data perturbations. The proposed approach aligns machine learning with actuarial portfolio optimization by explicitly integrating profit-driven objectives and operational constraints, offering two practical and scalable solutions for risk-based decision-making in real-world insurance settings.Item type: Artículo , Access status: Abierto , Biofloc characterization after achieving a stable population of Chlorella sp. for Penaeus vannamei culture (Bonne, 1931)(Elsevier, 2026-09-15) Cascales-Martos, Tatiana; Aguilar-Escribano, Javier; Brol, Jéssica; Jover Cerda, Miguel; Martínez-Llorens, Silvia; Tomas-Vidal, A.; Sánchez-Jerez, Pablo; Peñaranda, D.S.; GENERALITAT VALENCIANA; AGENCIA ESTATAL DE INVESTIGACION; Universitat Politècnica de València[EN] This study investigated the integration of microalgae into biofloc systems for Penaeus vannamei under controlled photoperiods, assessing effects on growth performance, water quality, and biofloc ecology. Two consecutive experiments were conducted: (1) evaluation of four photoperiod regimes (16:8, 12:12, 8:16, 0:24 light:dark) combined with Chlorella sp. or Phaeodactylum tricornutum, and (2) the comparison of microalgae or probiotic addition in a biofloc system. Chlorella sp. under 16:8 and 12:12 photoperiods maintained stable populations, promoted greater biodiversity, particularly complex zooplankton and improved mineral profiles by increasing boron and arsenic while reducing bromine. In the second experiment, Chlorella sp. persisted up to 32 days, contributing to nitrate reduction and enriching arachidonic and eicosapentaenoic acid content in the biofloc. However, in terms of growth, the better SGR obtained in the first assay was not confirmed in a second trial. Principal component analysis highlighted a consistent correlation between nitrate concentration and the performance of shrimp, as well as microalgae inoculation and PUFA increase on biofloc. Overall, Chlorella sp. under a 12:12 photoperiod enhanced biofloc quality and ecological diversity, supporting its potential for improving aquaculture system performance.Item type: Artículo , Access status: Cerrado , La Ciudad Vergel, un barrio con personalidad propia(Ayuntamiento de Elda. Concejalía de Cultura, 2025) Martínez-Pérez, Francisco-Juan; Busquier-Corbí, Jose-David[ES] La riqueza histórica de nuestra localidad es a todas luces indiscutible. Para cualquier amante, aficionado o profesional del campo historiográfico, resulta evidente la diversidad de acontecimientos que han dado forma a la ciudad que hoy tenemos ante nosotros, desde hechos políticos de envergadura, acontecimientos históricos variados o visitas de personajes relevantes, entre otros. Sin duda, el urbanismo, entendido como la planificación y estudio de los entornos urbanos, para intentar satisfacer las necesidades de las personas que los habitan, completa, además, el conocimiento para comprender el desarrollo, no solo físico, sino también social o económico de una ciudad. En este sentido, Elda, cuenta con numerosos acontecimientos que marcan ese desarrollo urbano, su crecimiento, modificación de viales, barriadas, etc.Item type: Artículo , Access status: Abierto , Open-source kinetic modelling of downdraft biomass gasification in Python: validation and parametric analysis of syngas quality(Elsevier, 2026-03-06) Chuquin-Vasco, Daniel; Torregrosa López, Juan Ignacio; Lo-Iacono-Ferreira, Vanesa G.; Universitat Politècnica de València[EN] An open-source, kinetic model for downdraft biomass gasification was developed in Python to provide a transparent and reproducible reactor-scale framework. The approach integrates coupled mass and energy balances with a 26-reaction kinetic set describing drying, multi-stage pyrolysis, oxidation, reduction, and tar cracking in a plug-flow configuration. Validation against laboratory-scale experimental data for Scots pine under air-blown conditions yielded an average mean absolute percentage error (MAPE) of 3.03% and a root mean square error (RMSE) of 0.6693 for major syngas species (CO, CO2, H2, CH4). Additional validation using Miscanthus briquettes and rubber wood confirmed predictive robustness without parameter re-tuning, maintaining RMSE values below the established acceptance threshold (RMSE <1.60). Parametric analysis was conducted across representative ranges of equivalence ratio (ER), addition of steam(S/B), and pyrolysis temperature. Increasing ER reduced tar from 27.63 to 1.21 g Nm¿3 but decreased syngas energy content beyond the optimal point (ER ¿ 0.32). The higher heating value (HHV) ranged from 4.02 to 5.24 MJ Nm¿3, while lower heating value (LHV) reached 4.97 MJ Nm¿3 at elevated pyrolysis temperatures. Steam addition increased H2 up to 12.99 vol% (¿37% increase) with limited tar reduction (<5%). Temperature exerted the strongest influence, promoting near-complete tar conversion (99.7%). Overall, the proposed framework supports parametric, and reproducible model-based design of downdraft gasifiers.
