Pulp and peel breadfruit flours as techno-functional ingredients. Rheological and staling behavior of their gels
No full textProducción CientíficaBreadfruit represents an exceptional nutritional source. However, its potential as a techno-functional food
ingredient remains largely unexplored. In this context, this study aimed to produce and characterize flours
derived from breadfruit (BF) pulp and peel in terms of their physical, techno-functional, pasting and rheological
properties. Banana flour was used as a reference for comparison purpose. BF flours formed heat-stable gels at a 4
% concentration, double the threshold required for banana flour, with higher water absorption capacity (+68 %),
swelling power (+75 %), and five-fold lower solubility than banana flour. BF-pulp flour demonstrated 10 %
higher emulsifying activity and 60 % higher emulsion stability. Additionally, it showed a higher pasting tem-
perature, increased final viscosity (+24 %), and substantially lower breakdown viscosity ( 75 %) compared to
banana. All gels exhibited pseudoplastic flow behavior, with BF-pulp presenting the highest consistency index
and thixotropy. Dynamic oscillatory tests revealed superior viscoelastic properties in BF-gels, with storage and
loss moduli exceeding those of banana gel at equivalent concentrations. Retrogradation kinetics showed faster
amylopectin recrystallization in BF gels, in particular those from BF-pulp flour, compared to banana gel, sug-
gesting an earlier achievement of structural stability during storage. In contrast, banana gels exhibited a higher
leveling-off retrogradation enthalpy, reflecting a firmer and more stable texture over long-term storage. These
findings position BF-pulp flour as a high-performance hydrocolloid, offering enhanced gel strength and emulsion
stability, suitable for gluten-free sauces or bakery fillings. Meanwhile, the lower viscosity and unique shear
rheology of BF-peel flour may benefit low-viscosity applications. The distinct viscometric and staling profiles
exhibited by BF-samples enable the design of novel foods with a wide range of textures.Ministerio de Ciencia, Innovación y Universidades (PID2023-153330OB-100)Junta de Castilla y León y el programa FEDER de la UE (CLU 2019-04 – Unidad de Excelencia BIOECOUVA de la Universidad de Valladolid)Universidad de Valladolid / Banco Santander: contrato predoctoral UVa de Caleb Samir Calix River
Two-Variable Domination Structures and Applications in Vector Optimization
No full textProducción CientíficaIn this paper, we introduce and study domination structures in real topological Hausdorff linear spaces that take into account the two involved points at each comparison. These binary relations are then applied to define notions of minimizer of a set and optimality concepts for vector optimization problems in the usual way, and their basic properties are obtained. Results on nonlinear scalarization to characterize them are also stated, which can be applied to vector optimization problems with variable ordering structures where the known ones do not work. Comparisons with results of the literature and illustrative examples are given as well.Ministerio de Ciencia, Innovación y Universidades (MICIU) / Agencia Estatal de Investigación (AEI) / Fondo Europeo de Desarrollo Regional (FEDER): PID2024-156273NA-I00 (MICIU/AEI/10.13039/501100011033 / FEDER, UE)Programa Erasmus+ KA171Open access funding provided by FEDER European Funds and the Junta de Castilla y León under the Research and Innovation Strategy for Smart Specialization (RIS3) of Castilla y León 2021-2027
On the development of high-performance, multi-GPU applications on heterogeneous systems leveraging SYCL
No full textProducción CientíficaComputational platforms for high-performance scientific applications are increasingly heterogeneous, incorporating multiple GPU accelerators. However, differences in GPU vendors, architectures, and programming models challenge performance portability and ease of development. SYCL provides a unified programming approach, enabling applications to target NVIDIA and AMD GPUs simultaneously while offering higher-level abstractions for data and task management. This paper evaluates SYCL’s performance and development effort using the Finite Time Lyapunov Exponent (FTLE) calculation as a case study. We compare SYCL’s AdaptiveCpp (Ahead-Of-Time and Just-In-Time) and Intel oneAPI compilers, along with different data management strategies (Unified Shared Memory and buffers), against equivalent CUDA and HIP implementations. Our analysis considers single and multi-GPU execution, including heterogeneous setups with GPUs from different vendors. Results show that, while SYCL introduces additional development effort compared to native CUDA and HIP implementations, it enables multi-vendor portability with minimal performance overhead when using specific design options. Based on our findings, we provide development guidelines to help programmers decide when to use SYCL versus vendor-specific alternatives.This work was supported in part by the Spanish Ministerio de Ciencia e Innovación and by the European Regional Development Fund’s “A Way of Making Europe” (NATASHA project, Grant PID2022142292NB-I00, funded by MCIN/AEI/10.13059/501100011033), by Junta de Castilla y León FEDER Grant VA226P20 (PROPHET-2 Project), EuroHPC Joint Undertaking for awarding us access to LUMI at CSC, Finland (project EHPC-DEV-2024D07-079), and by Grant TED2021-130367B-I00, funded by MCIN/AEI/10.13039/501100011033, and by Next Generation EU – Plan de Recuperación, Transformación y Resiliencia

No full textProducción CientíficaCombinatorial double auctions provide an efficient mechanism for resource allocation, maximizing social welfare without requiring private information from participants. However, depending on specific auction conditions, the number of rounds required for convergence can be significantly high. In this work, we extend a previously developed DEVS-based auction model to study the dynamics of social welfare evolution throughout the auction process. While the original model identifies the allocation that maximizes social welfare, our extension enables tracking the proportion of the optimal social welfare achieved at each round. This analysis provides insights into the auction's convergence behavior and serves as the foundation for developing an approach that helps auctioneers select appropriate parameters to achieve a sufficiently good outcome within a reasonable number of rounds in real-world scenarios.The authors wish to acknowledge MCIN/AEI, Spanish Government, and /10.13039/501100011033/FEDER UE, European Union, for the partial support through the PID2022-137948OA-I00 Research Project
Experimental investigation on heat transfer to supercritical CO2 in a microtube up to 30 MPa for application in the NET Power cycle
No full textProducción CientíficaMicrotube heat exchangers represent a high-performance alternative to conventional printed circuit designs for
the thermal recuperator of the innovative oxy-combustion NET Power cycle, offering potential improvements in
both system efficiency and compactness. To support this technology transition, this study presents an experi-
mental investigation of heat transfer in CO2 at supercritical pressures up to 30 MPa. Experiments were conducted
using a 1700 mm long, 0.88 mm inner diameter, uniformly heated horizontal microtube designed to replicate the
operating conditions of a microtube heat exchanger. An experimental setup was built to measure local heat
transfer coefficients of CO2, with a parametric analysis performed to evaluate the influence of mass flux, heat
flux, inlet temperature, buoyancy, and flow acceleration. Tests were conducted at pressures of 10, 15, 20, 25 and
30 MPa. Results show that the heat transfer improves with increasing mass flux. At 10 MPa, the heat transfer
coefficient exhibits a peak near the pseudo-critical temperature, followed by a deterioration and subsequent
recovery. With increasing thermal input, the peak is attenuated, while heat transfer performance improves at
higher pressures. Raising inlet temperatures enhances heat transfer in the thermal inflow region, reduces the
peak value at 10 MPa, and causes the heat transfer coefficients to converge across different pressures. Buoyancy
effects are most pronounced at 10 MPa and become weaker as pressure increases. Moreover, a new deep neural
network model was developed to predict heat transfer coefficients, demonstrating an average deviation of 6.34
%. The present study substantially expands the existing experimental database, provides new physical in-
terpretations of key phenomena, and translates these findings into a predictive tool applicable to engineering

Influence of biomilking on methanotrophs cultivation during biogas conversion into ectoines
No full textProducción CientíficaEctoine is one of the most profitable value chains for biogas valorisation. This study assessed the long-term
effects of biomilking for ectoine (Ect) and hydroxyectoine (Hy) extraction on upstream methane bioconversion
into ectoines using a halotolerant methanotrophic consortium cultivated in a Taylor-Flow bioreactor. After a
control stage (S-I), fractions of the culture broth volume of 10 %, 50 %, 30 % and 60 % (S-II to S-VI) were
subjected to biomilking before a final control (S-VII). No adverse effects were observed at 10 %, while higher
fractions led to salt depletion, a ~10 % reduction in CH4 bioconversion efficiency, and a loss of dominant ectoine
producers, mainly Methylomicrobium. A decrease in intracellular Ect was also observed. Restoring salt levels (S-
VI) recovered Methylomicrobium dominance and Ect content in the culture broth. Enhanced biomilking yielded up
to 27.2 g-Ect + Hy per inlet kg of CH4, supporting its feasibility for sustainable biogas valorisation at a com-
mercial scale.Esta investigación fue financiada por el proyecto Horizonte CHEERS de la UE, financiado por el programa de Investigación e Innovación Horizonte Europa de la Unión Europea bajo el Acuerdo de Subvención No 101060814Proyecto Horizonte Europa CHEERS cuentan con el apoyo de las subvenciones UKRI número 10050977 Earthwatch EuropeJunta de Castilla y León (Consejería de Educación) y la Unión Europea a través del Fondo Europeo de Desarrollo Regional (FEDER) (Referencia: CLU-2025-2-06

FROM CONCEPT TO PRAXIS: THE SEMIOTICS OF SUSTAINABILITY IN MANAGERIAL COMMUNICATION AND CORPORATE STRATEGY
No full textLa obra propone una lectura filológico-estratégica de la sostenibilidad empresarial, combinando la semiótica del discurso organizacional con los principios de la dirección estratégica. Tras un metaanálisis bibliométrico de 221 publicaciones (2000-2024) sobre sostenibilidad corporativa en Europa del Este, el libro identifica vacíos conceptuales y formula un modelo de “transferencia semiótica” que vincula la conciencia directiva, los imperativos normativos y la orientación al liderazgo con el rendimiento reputacional y financiero de la empresa. El modelo se contrasta empíricamente mediante 45 entrevistas en profundidad y una encuesta a 312 directivos de los sectores energético y de bienes de consumo en Rumanía y España. Los resultados revelan tres estrategias semióticas —legitimadora, dialógica y transformacional— que, cuando se alinean con la planificación estratégica, generan ventajas competitivas duraderas y reducen hasta un 12 % la brecha de percepción entre stakeholders internos y externos. Además, se ofrece un protocolo operativo para auditar la sostenibilidad desde la perspectiva del lenguaje organizacional, con indicadores transferibles a sistemas de reporting ESG. Con ello, la monografía aporta una herramienta pionera para investigadores y profesionales interesados en traducir la narración sostenible en valor tangible
