USTED ESTÁ AQUÍ. Estrategias de desplazamiento y reapropiación espacial en las prácticas artísticas contemporáneas
No full text[ES] La siguiente investigación aborda el desplazamiento como categoría estética, política y metodológica en el arte contemporáneo, a partir de una perspectiva que conjuga relaciones conceptuales entre prácticas culturales periféricas y producciones legitimadas, buscando abrir un espacio híbrido en el que ambas puedan dialogar. A través del estudio de manifestaciones situadas fuera del sistema institucional del arte, se indaga en formas de reapropiación espacial que operan desde la marginalidad, la desregulación y la subversión, examinando su potencial para contribuir como herramientas críticas y productivas, capaces de articular nuevas formas de presencia, circulación y resistencia en la ciudad contemporánea. Desde una metodología que combina praxis artística, revisión teórica, numerosos ejemplos y análisis de obras, trabajo de campo y diálogo con otras voces involucradas, se estudia cómo estas formas de acción permiten repensar las nociones de obra, autoría, espacio público y representación. Este trabajo se propone investigar las posibilidades de documentar y traducir estas experiencias en formatos artísticos contemporáneos, conservando sus valores originales y evitando su neutralización en la medida de lo posible.[CA] La següent investigació aborda el desplaçament com a categoria estètica, política i metodològica en l'art contemporani, des d'una perspectiva que conjuga relacions conceptuals entre pràctiques culturals perifèriques i produccions legitimades, amb la voluntat d'obrir un espai híbrid on ambdues puguen dialogar.

Aquest treball es proposa investigar les possibilitats de documentar i traduir aquestes experiències en formats artístics contemporanis, tot conservant-ne els valors originals i evitant, en la mesura del possible, la seua neutralització.[EN] This research addresses displacement as an aesthetic, political, and methodological category in contemporary art, from a perspective that weaves conceptual relationships between peripheral cultural practices and legitimized productions, seeking to open a hybrid space in which both can engage in dialogue. Through the study of manifestations situated outside the institutional art system, it explores forms of spatial reappropriation that operate from marginality, deregulation, and subversion, examining their potential to function as critical and productive tools capable of articulating new forms of presence, circulation, and resistance in the contemporary city. Using a methodology that combines artistic practice, theoretical review, numerous examples and artwork analysis, fieldwork, and dialogue with other involved voices, this study investigates how these forms of action allow us to rethink notions of the artwork, authorship, public space, and representation. This work aims to investigate the possibilities of documenting and translating these experiences into contemporary artistic formats, preserving their original values and avoiding their neutralization as much as possible.Martínez Torrente, J.

A combined Method Of Lines and Orthogonal Collocation with Second kind Chebyshev nodes for convection diffusion reaction equation with Danckwerts Conditions
No full text[EN] We analyze and develop two numerical methods to solve the convection¿diffusion¿reaction equation with Danckwerts boundary conditions. One of the methods is an approach based on the method of lines using spatial discretization by orthogonal collocation. While this method has been applied to other equations, it has not been previously studied for this particular case. Furthermore, the convergence of the method is demonstrated for various values of the Péclet and Damköhler numbers. We also describe the implementation of a weighted residual method by orthogonal collocation method, using Lagrange polynomials and Chebyshev nodes of the second kind to solve the same problem. Both methods are presented in matrix form to facilitate its implementation in Matlab. Finally, we compare the results with both the analytical solution and those from a previous conventional method of lines discretization based on finite differences, implemented by the authors. The computed errors demonstrate that the adapted method of lines with orthogonal collocation yields a more accurate overall approximation than the alternative approaches.Funding for open access charge: CRUE-Universitat Politècnica de València.Agud Albesa, Lucia;Boix García, Macarena;Torregrosa Sánchez, Juan Ramón (2026).

Thermal and Acoustic Characterization of Recycled Ground Tyre Rubber and Aggregate Seismic Isolator
No full text[EN] Currently, large amounts of aggregate waste from the construction industry and ground tire rubber from the automotive sector are being generated. Enhancing and expanding recycling options for these materials is essential to support the transition toward a circular economy in both industries. This study proposes the use of recycled materials in the development of a seismic isolator designed for building partitions. As such, the new element must meet the performance requirements applicable to all materials used in building enclosures. Polyurethane is employed as a binder for the recycled components. The composite material is produced by combining polyurethane with varying proportions of recycled ground tire rubber and aggregates, expressed as a percentage of the polyurethane mass. The polyurethane is directly mixed with the recycled constituents. The resulting samples are subjected to thermal and acoustic testing to evaluate their suitability for partitions and enclosures in building construction in accordance with regulations. The results of the three tests indicate improvements in the measured properties, with the magnitude of enhancement depending on the ratio of ground tire rubber to aggregate. Overall, the developed composite materials exhibit characteristics and behavior compatible with the intended application.This work was made possible thanks to the following projects: 1.

Estudi del paper de proteïnes tipus VAP com a reguladors generals de l'endocitosi en Arabidopsis
No full text[ES] El canal de potasio KAT1 es un actor clave en la determinación de la dinámica del movimiento estomático, que controla la pérdida de agua por transpiración y desecación. Por lo tanto, sus reguladores pueden ser dianas para desarrollar en el futuro herramientas biotecnológicas para mejorar o generar plantas resistentes a la sequía. Este canal de la membrana plasmática (PM) está altamente regulado y un screening por interacción proteína-proteína nos permitió identificar y caracterizar varios reguladores de KAT1. Uno de ellos pertenece a la familia VAP de proteínas asociadas a VAMPs (proteínas de membrana asociadas a vesículaspero poco se sabe sobre esta proteína.
En el genoma de Arabidopsis, se han identificado diez homólogos de VAP (VAP27-1 a VAP27-10) y se pueden dividir en tres clados distintos. Las proteínas VAP27-1 y VAP27-3 se localizan en las uniones ER-PM e interactúan con clatrina y lípidos PIP de las membranas endocíticas, lo que les permite unirse al RE y mantener así el tráfico endocítico general en Arabidopsis. Sin embargo, en mutantes dobles por pérdida de función vap27-1/vap27-3, la endocitosis sólo está parcialmente comprometida. Nuestra hipótesis es que el regulador de KAT1 de tipo VAP que hemos identificado puede participar en la endocitosis y/o el tráfico de KAT1 hacia o desde la PM pero también tener un papel más general en la endocitosis y tal vez complete el papel de VAP27-1 y VAP27-3.
La endocitosis es un proceso esencial, y la endocitosis mediada por clatrina (CME) es un mecanismo importante que controla el proteoma de la PM. Cómo se asocia la clatrina a los subdominios de la membrana no está completamente entendido. En las células vegetales, la homeostasis de la endocitosis depende de la interacción del RE con las membranas endocíticas, pero los mecanismos subyacentes son aún desconocidos. Si se confirma una función general en endocitosis para este regulador de KAT1 tipo VAP, sería una proteína de gran interés en términos del tráfico de membranas en células vegetales y ayudará a descifrar los mecanismos moleculares de la endocitosis en plantas. El hecho de que interactúe físicamente con KAT1 resulta de gran interés para conocer el mecanismo de endocitosis de dicho canal de potasio.
En este trabajo se generan dobles y triples mutantes de Arabidopsis por pérdida de función de VAP27-1, VAP27-3 y el regulador de KAT1 tipo VAP indentificado. Para ello se disponía de los mutantes simples y el mutante doble vap27-1/vap27-3. Estos nuevos mutantes permitirán analizar la endocitosis general en los mismos, y determinar el papel de este regulador tipo VAP en dicha endocitosis general. Por otro lado, en este trabajo se generan las construcciones necesarias para estudiar la posible interacción de este regulador tipo VAP, así como de KAT1, con la clatrina por BiFC y CoIP. Para dicho análisis se utiliza la agroinfiltración en Nicotiana, así como la microscopía confocal de fluorescencia y el Western blot. Estos ensayos permitirán entender mejor el mecanismo de endocitosis de KAT1 en plantas.[EN] The potassium channel KAT1 is a key player in determining the dynamics of stomatal movement, which controls water loss through transpiration and desiccation. Therefore, its regulators may be targets for the future development of biotechnological tools to improve or generate drought-resistant plants. This plasma membrane channel of guard cells is highly regulated, and a protein–protein interaction screening allowed us to identify and characterize several regulators of KAT1. One of them belongs to the VAP family of VAMP-associated proteins (vesicle-associated membrane proteins), but little is known about this protein.
In the Arabidopsis genome, ten members of the VAP family (VAP27-1 to VAP27-10) have been identified and can be divided into three distinct clades. The proteins VAP27-1 and VAP27-3 interact with clathrin and PIP lipids of endocytic membranes, which allows them to bind to the endoplasmic reticulum and thus maintain general endocytic trafficking in Arabidopsis thaliana. However, in double loss-of-function vap27-1/vap27-3 mutants, endocytosis is only partially compromised. Our hypothesis is that the VAP-type KAT1 regulator that we have identified may participate in the endocytosis and/or trafficking of KAT1 to or from the plasma membrane, but may also have a more general role in endocytosis and perhaps complement the role of VAP27-1 and VAP27-3.
Endocytosis is an essential process, and clathrin-mediated endocytosis (CME) is an important mechanism that controls the plasma membrane proteome. How clathrin associates with membrane subdomains is not completely understood. In plant cells, endocytic homeostasis depends on the interaction of the endoplasmic reticulum with endocytic membranes, but the underlying mechanisms are still unknown. If a general function in endocytosis is confirmed for this VAP-type KAT1 regulator, it would be a protein of great interest in terms of membrane trafficking in plant cells and would help to decipher the molecular mechanisms of endocytosis
in plants. The fact that it physically interacts with KAT1 is of great interest for understanding the mechanism of endocytosis of this potassium channel. In this work, double and triple loss-of-function mutants of Arabidopsis thaliana for VAP27-1, VAP27-3, and the identified VAP-type KAT1 regulator were generated. For this purpose, single mutants and the vap27-1/vap27-3 double mutant were available. These new mutants will
make it possible to analyze general endocytosis in them and to determine the role of this VAPtype regulator in such general endocytosis. On the other hand, in this work the necessary constructs were generated to study the possible interaction of this VAP-type regulator, as well as KAT1, with clathrin by BiFC and CoIP. For this analysis, agroinfiltration in Nicotiana benthamiana was used, as well as confocal fluorescence microscopy and Western blotting. These assays will allow a better understanding of the mechanism of KAT1 endocytosis in plants.Morcillo Teruel, G. (2026).

Evaluation of Postgraduate Architect Candidates' Opinions on the Use of 3D Printers
No full text[EN] Nowadays, when technology is developing at a rapid pace, new technological devices are being developed to become a part of both professional life and educational programs. One of these technological developments is the development of the development of three-dimensional printers. Recently, presentations have been presented in three dimensions and multimedia, allowing professionals to have better knowledge about these tools and their uses. 3D printers are rapidly becoming tools that support the production and creation process in small and medium-sized businesses. These printers are used not only for prototyping but also in many fields such as industrial planning, engineering, design, architecture, medicine, and scientific research. The aim of this study is to reveal the opinions of graduate architect candidates regarding the use of 3D printers within the scope of architectural education. The main reason for choosing graduate-level architects as the sample group is that they have reached a certain level by completing their undergraduate education and have a level of awareness in terms of increasing their competencies by continuing their education at the graduate level. In the study, data was collected using an opinion form with semi-structured questions. Participation in this study was provided on a voluntary basis. As a result of the study, it has been proven that the use of 3D printing will have an important place in the future of architecture, as will 3D representation and 3D models. This situation has revealed the awareness that future architects need to be supported and trained in this regard.Taşan, LE.;İsmailoğlu, S. (2026).

Robust grid forming control for black start operation of diode rectifier based wind power plants
No full text[EN] Black start capability of off-shore wind power plants is an important feature to reduce the number of traditional power plants required for robust system operation. The impedance seen by each wind turbine shows a large variation during the complete black start procedure, normal operation and during faults. This paper proposes a controller design methodology for the voltage control of grid-forming wind turbines based on mu-synthesis optimisation that ensures the stability of the wind power plant during all the considered modes of operation (black start operation, normal operation and faults). The use of mu-synthesis optimisation leads to the optimal controller in terms of robustness and performance for all the impedance variations that occur during the operation of the wind power plant, as is confirmed by the obtained results. The results include Matlab simulations for a limited number of wind turbines and a validation on a real-time co-simulation of a detailed large scale wind power plant, including detailed aeroelastic, mechanical, electric and power electronic models of the complete wind power plant.Authors would like to acknowledge the support of the Spanish Research Agency through Grant TED2021-130120B-C21 funded by MCIN/AEI/10.13039/501100011033 and by the European Union NextGenerationEU/PRTR, Grant PID2020-112943RB-I00, grant PID2023-146747NB-C21 funded by MCIN/AEI/10.13039/501100011033 and by ERDF/EU; and grant FPU22/00791 funded by Ministerio de Ciencia Innovacion y Universidades, Spain.Navarro-Martínez, Gala;Martínez-Turégano, Jaime;Sala, Antonio;Blasco-Gimenez, Ramon (2026).

Design and Manufacturability-Aware Optimization of a 30 GHz Gap Waveguide Bandpass Filter Using Resonant Posts
No full text[EN] This paper presents the design and optimization, based on electromagnetic simulation, of a fifth-order bandpass filter centered at 30 GHz, implemented using Gap Waveguide (GWG) technology and pole-type cylindrical resonators, intended for applications in 5G communication systems and high-frequency satellite links. Unlike conventional Chebyshev designs reported in the literature, this study proposes an integrated methodology that combines theoretical synthesis, full-wave electromagnetic modeling, and multivariable optimization, while accounting for manufacturing constraints. The developed method encompasses the electromagnetic characterization of individual resonators, the extraction of cavity-cavity coupling parameters, and the complete implementation of the filter using full-wave electromagnetic simulations. A distinctive aspect of the proposed approach is the explicit incorporation of practical manufacturing effects, such as rounded corners induced by machining processes, alongside analytical and numerical geometric compensation procedures that preserve the device's electrical response. Furthermore, a combination of gradient-based optimization algorithms and evolutionary strategies is employed to align the electromagnetic response with the target theoretical behavior. The results obtained through electromagnetic simulation indicate that the designed filter achieves return losses exceeding 20 dB and a fractional bandwidth of 4.95%, consistent with the reference Chebyshev response. Finally, the potential extension of the proposed approach to higher frequency bands is discussed conceptually, laying the groundwork for future work that includes experimental validation.Ccasani-Davalos, A.;Sacoto-Cabrera, EJ.;Utrilla Mego, LW.;Herrera-Levano, JC.;Coaquira-Castillo, RJ.;Concha-Ramos, Y.;Moreno-Cardenas, E.

Optimizing reactive maintenance intervals for the sustainable rehabilitation of chloride-exposed coastal buildings with MMC-based concrete structure
No full text[EN] Coastal cities face significant challenges in maintaining their infrastructure due to harsh environmental conditions, such as high humidity and airborne chlorides, which accelerate material degradation. This issue is particularly critical for reinforced concrete structures in beachfront buildings, such as hotels, where corrosion is a common and progressive problem. Timely maintenance and repair are essential to prevent structural failures caused by accidental loads, such as wind or earthquakes, which can compromise safety. Historically, the focus in construction has been on reducing environmental impact, often overlooking the importance of maintenance and end-of-life stages. This paper presents a novel, integrated methodology combining preventive design assessment with reactive maintenance optimization to study the sustainability of repair strategies for maintenance in coastal cities of buildings with reinforced concrete exposed to chloride-induced corrosion. The study focuses on structures based on Modern Methods of Construction (MMC) to minimize life cycle impact by optimizing material consumption compared to traditional construction. Twelve preventive design alternatives are evaluated, each subjected to four maintenance strategies addressing different damage levels caused by deterioration throughout the structure's service life. A FUCOM-TOPSIS model aggregates eight sustainability criteria¿economic costs, life-cycle environmental burdens, and social performance indicators¿to identify optimal year-by-year maintenance intervals and rank alternatives. Results reveal that the most sustainable designs involve multiresistant cement, hydrophobic anti-corrosion impregnation, and silica fume additive, achieving sustainability ratings up to 86 % higher than the baseline. This approach enhances the resilience and sustainability of coastal infrastructure, effectively addressing challenges posed by harsh environmental conditions and supporting long-term, sustainable urban development.Grant PID2023-150003OB-I00 funded by MICIU/AEI/10.13039/501100011033 and by "ERDF/EU".Sánchez-Garrido, AJ.;Navarro -Martinez, Ignacio Javier;Yepes, V.
