Inovative Strategies Based on LCA for Wind Turbine Eco- Design: Overcoming Barriers to Enhance Sustainability
No full text[EN] The expansion of wind energy increases its global environmental impact. While academic research has assessed the potential effects
of wind turbines, it has not sufficiently addressed strategies to mitigate their impact. This study examines a leading turbine manufacturer
with a
strong
environmental

to
explore
solutions.
Life

However,
its
effectiveness
is
hindered
by
several
challenges.
Continuous

Synthesis, characterisation, and thermal degradation kinetics of lignin-based polyurethane wood adhesives
No full textPolyurethane adhesives are widely employed in a range of industrial applications due to their exceptional bonding strength, flexibility, and chemical resistance. These materials play a crucial role in wood bonding technologies, where their versatility and durability make them ideal for creating strong, long-lasting joints. In this work, Four different polyurethane wood adhesives were synthesised using ligno-based bio-polyols obtained through microwave assisted liquefaction reaction of two wood species (hardwood and softwood) using polyethylene glycol and glycerol as solvents. The reaction conditions used for the synthesis of bio-polyols were optimised in a previous work. The synthesis of polyurethanes was carried out by one-shot method using Tetrahydrofuran (THF) as solvent and MDI as diisocyanate employing different NCO:OH ratios (2.0:1, 2.5:1, and 3.0:1). The chemical structure of polyurethanes was determined through ATR-FTIR and the shear strength was analysed using Automated Bonding Evaluation System (ABES) employing beech veneer strips. Through ABES it was concluded that an NCO:OH ratio of 2.5:1 was the formulation that showed the best shear strength for a pressing time of 120 s. Employing this ratio and the same synthesis procedure, two new polyurethanes were synthesised with the bio-polyols obtained using crude glycerol instead commercial glycerol. Finally, a study of thermal degradation kinetics employing the Ozawa–Flynn–Wall (OFW) and Kissinger–Akahira–Sunose (KAS) isoconversional methods of the polyurethanes synthesised with an NCO:OH ratio of 2.5:1 was carried out. On the one hand, the Ea of each system were estimated for the different α ratios, obtaining slightly higher values for the adhesives produced using commercial glycerol than crude glycerol. In addition, the pre-exponential factor was determined, enabling an estimation of the lifetime of the polymers. This study highlights demonstrated that crude glycerol could replace commercial glycerol without compromising adhesive properties. The findings revealed that the lignin source significantly influences the adhesive's characteristics and stability, while addressing challenges in achieving industrial viability remains essential for broader application.The authors wish to acknowledge the financial support provided by the Basque Government (IT1498-22) and the national funds FCT/MCTES (PIDDAC): LEPABE, UIDB/00511/2020 (DOI: 10.54499/UIDB/00511/2020), ALiCE, LA/P/0045/2020 (DOI: 10.54499/LA/P/0045/2020) and CERNAS (UIDB/00681/2020 DOI: 10.54499/UIDB/00681/2020).

Slow Creativity. Metodología proyectual de creación, basada en el pensamiento complejo y sistémico de la creatividad, el Ashtanga Yoga y el movimiento Slow Design
No full text520 p.Esta investigación plantea la necesidad de reformular los procesos creativos en un contexto de inmediatez, estrés e hiperproductividad. A pesar de la creciente integración de la sostenibilidad en el diseño, las metodologías creativas no han evolucionado hacia prácticas más pausadas, reflexivas y alineadas con valores éticos. Desde esta perspectiva, se propone fomentar la conexión entre los procesos internos de los diseñadores/as, la intuición y la emoción, promoviendo una creación más coherente y significativa.Las preguntas de investigación se centran en cómo el Slow Design puede anticiparse a los impactos de los productos y en cómo mejorar la autoconciencia en los procesos creativos. La hipótesis plantea que la integración del Slow Design y el Ashtanga Yoga, dentro del pensamiento complejo y sistémico, evitan la estandarización y potencian creaciones genuinas.Se utilizó una metodología de Investigación Acción Participativa (IAP) con enfoque cualitativo y cuantitativo, aplicada a estudiantes y profesionales del diseño. La metodología proyectual Slow Creativity, ha demostrado un impacto transformador en los procesos creativos, con aplicaciones en múltiples sectores creativos. Su contribución radica en la generación de un marco teórico-práctico replicable que integra la meditación como herramienta clave, fomentando la autoconciencia intuitiva y reflexiva. Además, se presenta como una herramienta accesible e innovadora, alineada con los desafíos contemporáneos, permitiendo una conexión más profunda entre el creador, su obra y el entorno

Relación de las competencias emocionales del profesorado con la ansiedad, el rendimiento académico y las competencias emocionales de Educación Primaria
No full textNumerosos estudios han destacado la relevancia de las competencias emocionales en la labor docente y en el desarrollo del alumnado. Sin embargo, son pocos los que analizan cómo estas competencias en el profesorado influyen en el bienestar, el rendimiento académico y el desarrollo emocional de los estudiantes. El presente estudio evalúa las competencias emocionales del profesorado y su relación con variables clave en el alumnado de Educación
Primaria: competencias emocionales, ansiedad y rendimiento académico. La muestra incluye 118 docentes y 1676 alumnos de educación primaria de diferentes centros educativos de España. Se utilizó un diseño cuantitativo no experimental, con análisis descriptivo y comparativo-causal ex-post-facto a través del software SPSS en su versión 28.0. Los instrumentos aplicados fueron el Cuestionario de Desarrollo Emocional (CDE-A-35), el Cuestionario de Desarrollo Emocional (CDE 9-13), la Escala de Observación de Competencias emocionales, la Escala de Ansiedad en Niños (CAS), el Inventario de Ansiedad estado-rasgo
en Niños (STAIC) y el promedio global de calificaciones. Los resultados evidencian que no existen correlaciones significativas entre las competencias emocionales del profesorado y las de sus estudiantes en los cursos iniciales, mientras que en los cursos superiores de Educación Primaria sí muestran una asociación significativa. Además, las competencias emocionales del profesorado correlacionan significativamente y de manera negativa con la ansiedad del alumnado en los cursos más avanzados. A pesar de no haberse identificado una relación directa entre competencias emocionales del docente y el rendimiento académico
del alumnado, los resultados destacan la importancia de promover el desarrollo de dichas competencias tanto en docentes como en estudiantes. En conclusión, el estudio presentado ofrece un enfoque novedoso ante la escasa investigación en este ámbito y pone de relieve la necesidad de integrar la educación emocional en la formación docente y en el currículum escolar, con el fin de favorecer el bienestar y el desarrollo emocional del alumnado a lo largo de su trayectoria educativa.Esta investigación es parte del proyecto de I+D+i / ayuda RTI2018-098294-B-I00/PRE2019-091604, financiada por MCIN/ AEI/10.13039/501100011033/ FEDER «Una manera de hacer Europa»
Poly (I:C)-induced maternal immune activation generates impairment of reversal learning performance in offspring
No full textMaternal immune activation (MIA) induces a variety of behavioral and brain abnormalities in offspring of rodent models, compatible with neurodevelopmental disorders, such as schizophrenia or autism. However, it remains controversial whether MIA impairs reversal learning, a basic expression of cognitive flexibility that seems to be altered in schizophrenia. In the present study, MIA was induced by administration of a single dose of polyriboinosinic-polyribocytidylic acid (Poly (I:C) (5 mg/kg i.p.)) or saline to mouse pregnant dams in gestational day (GD) 9.5. Immune activation was monitored through changes in weight and temperature. The offspring were evaluated when they reached adulthood (8 weeks) using a touchscreen-based system to investigate the effects of Poly (I:C) on discrimination and reversal learning performance. After an initial pre-training, mice were trained to discriminate between two different stimuli, of which only one was rewarded (acquisition phase). When the correct response reached above 80% values for two consecutive days, the images were reversed (reversal phase) to assess the adaptation capacity to a changing environment. Maternal Poly (I:C) treatment did not interfere with the learning process but induced deficits in reversal learning compared to control saline animals. Thus, the accuracy in the reversal phase was lower, and Poly (I:C) animals required more sessions to complete it, suggesting impairments in cognitive flexibility. This study advances the knowledge of how MIA affects behavior, especially cognitive domains that are impaired in schizophrenia. The findings support the validity of the Poly (I:C)-based MIA model as a tool to develop pharmacological treatments targeting cognitive deficits associated with neurodevelopmental disorders.This work was supported by the Spanish Ministry of Science, Innovation and Universities and European ERDF Funds (SAF2013/48586-R and 2017/88126-R), the Basque Government (IT-1211–19; IT-1512–22; IKUR Neurobiosciences Strategy), and the CIBER-Consorcio Centro de Investigación Biomédica en Red-Instituto de Salud Carlos III

Immortalized human hair follicle-derived mesenchymal-like stromal cells for the long-term production of scalable immunomodulatory and regenerative secretome
No full textBackground: Mesenchymal stromal cells (MSCs) exert therapeutic effects primarily through their secretome, rich in bioactive factors with immunomodulatory and regenerative properties. However, clinical application of MSC-derived secretome is hindered by donor variability, limited expansion, and replicative senescence. To address these issues, we developed immortalized human hair follicle-derived mesenchymal-like stromal cells (iHF-MSCs) as a consistent and scalable source of therapeutic secretome.
Methods: HF-MSCs were isolated using a minimally invasive procedure and immortalized with lentiviral SV40 large T antigen. From 576 single-cell clones, C18 and C26 were selected based on proliferation capacity, absence of senescence, and retention of a mesenchymal-like phenotype. Characterization included RT-PCR, flow cytometry for surface markers, trilineage differentiation, and CD56 expression analysis. For immunomodulatory evaluation, cells were licensed with IFN-γ and TNF-α, and the resulting conditioned media (licensed CM) were analyzed by ELISA and cytokine arrays. PBMC proliferation and Treg induction were assessed using licensed CM, while unlicensed CM was tested for its regenerative effects on dermal and epidermal cell functions, including wound repair, tube formation assay as an indicator of angiogenic potential, and oxidative stress response.
Results: The selected clones (C18 and C26) exhibited long-term stability, rapid expansion, and preserved mesenchymal-like phenotype and multipotency. Secretome profiling revealed an enriched composition of immunoregulatory (e.g., Gal-9, IL-1Ra, TSG-6) and pro-regenerative (e.g., VEGF, PDGF-AA, EGF) factors, with enhanced responsiveness to inflammatory licensing. Notably, iHF-MSCs maintained low immunogenicity and demonstrated superior functional performance: inhibition of PBMC proliferation, Treg induction, and promotion of skin cell proliferation, migration, tube formation, and oxidative stress protection.
Conclusion: These results position iHF-MSCs as a robust and scalable platform for consistent production of therapeutic secretome, paving the way for innovative, cell-free immunomodulatory and regenerative therapies.This work was supported by Grant PID2021-122577OB-I00 funded by MCIN/AEI/ https://doi.org/10.13039/501100011033 and by “ERDF A way of making Europe”.

Conceptualising identity, nostalgia and resistance: activism by the iranian diaspora in spain (1979-2024)
No full text559 p.This thesis has analysed the discourses and strategies of resistance and solidarity of Iranians in Spain, in their transnational social and political connections with civil resistance struggles related to socio-political conflicts in Iran, from 1979 until 2024. This investigation has placed attention on three sites of concern, seeing them as interrelated: 1) the nostalgia, memory and trauma related to the Iranian political scene felt from a distance; 2) the construction and negotiation regarding home and belonging; and 3) practices of resistance and solidarity in the diaspora. This study has centred on the stories of migrants that have left Iran after the Islamic Revolution of 1979 and shows the connection of this diaspora to socio-political conflicts in the homeland. This work has included the analysis of 39 semi-structured interviews carried out to first and second-generation Iranians in Spain between 2019 and 2024. The main conclusions of this work demonstrate that 1) civil resistance struggles in Iran have shown a continuity since the XIX century until today; 2) the Iranian diaspora in the West has been supporting Iranian civil society during civil resistance struggles since the first wave of migration and; 3) the Iranian diaspora in Spain is politically fragmented, in the same way as in other countries, and supports civil resistance struggles in Iran via human rights advocacy
Exploring the pathways linking prenatal and early childhood greenness exposure to attention-deficit/hyperactivity disorder symptoms during childhood: An approach based on robust causal inference
No full textBackground
Epidemiological studies suggest that exposure to greenness during childhood may protect children from developing attention-deficit hyperactivity disorder (ADHD).
Objective
We analyzed the effect of both prenatal (pregnancy) and early childhood (4-5-year follow-up) residential greenness exposure and green space availability on ADHD symptoms during childhood (up to the age of 12 years) and further explored the potential mediating role of PM2.5 and physical activity in the association.
Methods
The study population included participants from the INfancia y Medio Ambiente (INMA) prospective birth cohort (Gipuzkoa, Sabadell, and Valencia). Average Normalized Difference Vegetation Index (NDVI) in buffers of 100-, 300- and 500-m around the residential addresses was used as an indicator of greenness, while green space availability was determined based on the presence of a major green space within 150-m from the residence. Childhood ADHD symptoms were assessed at the 6-8- and 10-12-year follow-ups using Conners Parents Rating Scale-Revised: Short Form.
Results
Although no association was found for the prenatal exposure period, increased early childhood NDVI inversely associated with the OR of clinically significant ADHD symptoms during the 6-8-year follow-up at the 100-m (OR 0.03, 95% CI: 0.003 to 0.44), 300-m (OR 0.04, 95% CI: 0.003 to 0.42) and 500-m (OR 0.08, 95% CI: 0.01 to 0.76) buffers, but exclusively in the context of direct effects. Additionally, the 10-12-year follow-up analysis found moderate to weak evidence of potential total and direct effects of NDVI at both 100- and 300-m buffers on inattention scores, as well as for NDVI at the 300-m buffer on ADHD index scores. The analysis did not reveal evidence of mediation through PM2.5 or physical activity.
Conclusions
The evidence suggests that early childhood greenness exposure may reduce the risk of developing ADHD symptoms later in childhood, and that this association is not mediated through PM2.5 and physical activity.NMA-Gipuzkoa cohort was funded by grants from Instituto de Salud Carlos III (FIS-PI06/0867, FIS-PI09/00090, FIS-PI13/02187, FIS-PI18/01142 and FIS-PI18/01237incl.
