En los últimos años, los investigadores han prestado cada vez más atención a los compuestos bioactivos de origen alimentario por sus propiedades antiinflamatorias y preventivas en el desarrollo de enfermedades asociadas al estrés oxidativo
The IndagApp mobile app: an inquiry-based science teaching resource: usability evaluation with pre-service teachers
No full textVirtual laboratories and simulations have emerged as innovative solutions for science teaching. However, existing resources have various limitations and constraints including cognitive load/mental burden and limited coverage of all necessary steps in scientific inquiry, focusing mainly on the experimental simulation. To bridge this gap and address these challenges, the present study introduces the design and usability evaluation of IndagApp, an innovative educational resource explicitly developed to support inquiry‑based science teaching. A convergent mixed methods design and a convenience sampling of 90 pre‑service teachers were used. The findings indicate that IndagApp exhibits a high level of technological and pedagogical usability. Feedback from the users was incorporated to improve the app, resulting in its f inal version, which incorporates best practices from existing literature on authentic inquiry‑based science teaching. IndagApp is freely accessible in the Spanish language, and compatible with Android 5.0 + smartphones and tablets, as well as PCs running Windows 7 or above operating systems. This research provides a timely and significant educational resource that may assist educators in enacting reform‑oriented teaching practices.This study has been funded by the Agencia Estatal de Investigación de España [Spanish State Investigation Agency] under the grant number PID2020‑117348RBI00

Improvement of Motor Imagination and Manual Ability Through Virtual Reality and Selective and Nonselective Functional Electrical Stimulation: Protocol for a Randomized Controlled Trial
No full textProtocoloBackground: Motor imagery (MI) is a cognitive process that has been shown to be useful in the rehabilitation process after brain injury. Moreover, functional electrical stimulation (FES) and virtual reality (VR) have also been shown to be effective interventions in many parameters, and there is some evidence of their contribution to the improvement of MI capacity. Objective: This study aimed to compare the improvements in MI parameters, grip strength, and manual dexterity obtained using VR, FES, and selective FES based on multifield electrodes in healthy people. Methods: This clinical randomized controlled trial (RCT)with 4 branches will involve 80 healthy university students, with blinded third-party assessment. Participants will be divided into 4 groups: control (no intervention), selective FES (Fesia Grasp), traditional FES (Globus Elite), and Virtual Rehab Hands (Leap Motion sensor). Each group will receive 5 daily sessions, and assessments will be conducted at baseline, postintervention, and follow-up. The Movement Imagery Questionnaire-Revised (MIQ-RS) and chronometry will be used to assess MI, strength will be measured with a digital dynamometer, and manual dexterity will be evaluated with the Nine Hole Peg Test (NHPT) and the Box and Block Test (BBT). Statistical analyses will include 2-way repeated-measures ANOVA with post hoc Bonferroni correction to compare group differences over time, with nonparametric tests (eg, Kruskal-Wallis) being used if normality or variance assumptions are violated. The study will be organized into 3 phases: preparation, data collection, and analysis. The preparation phase will involve finalizing project protocols and obtaining ethical approvals. The data collection phase will consist of recruiting participants, randomizing them into 4 intervention groups, and conducting baseline assessments, followed by intervention sessions. Finally, the analysis phase will focus on evaluating the data collected from all groups and compiling the results for presentation. Results: The study received approval in July 2023, with recruitment and data collection starting in September 2023. The recruitment phase was expected to conclude by July 2024, and the entire study, including the 2-week follow-up, was set to finish in September 2024. As of July 2024, we had enrolled 100% of the sample (N=80 students). We plan to publish the study findings by the end of 2024. Conclusions: Improvements in MI and upper limb functionality are expected, particularly in the selective FES group. This RCT will identify which intervention is most effective in enhancing these skills, with potential benefits for patients with neurological motor disorders.

Social alienation as a bridge between unemployment and support for political violence.
No full textFrom a peacebuilding perspective, understanding the factors that lead to radicalization is the first step in preventing political violence, resisting its effects, and building solid pillars for peace. Along these lines, this research aims to explore the relationship between economic factors and radicalization, particularly between unemployment and support for political violence. As previous research has shown contradictory results, we suggest the need to explore the psychological factors that mediate the relationship between unemployment and support for political violence. Particularly, we suggest social alienation and moral disengagement. Therefore, we hypothesize that (Hypothesis 1) the unemployed will present greater social alienation, (Hypothesis 2) a greater sense of social alienation will be associated with greater support for political violence, and the relationship between employment status and political violence will be mediated by (Hypothesis 3) social alienation and (Hypothesis 4) moral disengagement. A study was conducted to test these hypotheses using a sample of employed (N = 281) and unemployed (N = 285) Spanish participants in Southern Spain. Participants completed a paper questionnaire in which they reported their employment status, social alienation, moral disengagement, and support for political violence. The results showed that the hypotheses were fulfilled and that social alienation and moral disengagement mediated the relationship between unemployment and political violence. According to these results, unemployment may encourage support for violence for political purposes. For this to be the case, perceptions of rejection must be considered. This underscores the need for interventions aimed at the welfare of the unemployed as well as their integration into society.: This research was conducted as part of project PID2020-116646RB-I00 funded by MCIN/AEI/10.13039/501100011033 and as part of the project DigiPatch funded by the European Union’s Horizon 2020 Research and Innovation Programme under CHANSE ERA NET (10100450
Water transport and porosity trends of concrete containing integral additions of raw-crushed wind-turbine blade
No full textRaw-Crushed Wind-Turbine Blade (RCWTB) is a novel material from the recycling and non-selective crushing of wind-turbine blades composed of fiberglass-composite fibers and polyurethane and balsa-wood particles. This research evaluates for the first time the water-transport and porosity behaviors of concrete with RCWTB through water-penetration-under-pressure, full-immersion water-absorption, capillarity-water-absorption and mercury-intrusion-porosimetry tests. RCWTB contents of 1.5%, 3.0%, 4.5%, and 6.0% were considered. All the RCWTB concretes yielded adequate results for depth of water penetration under pressure and water-absorption rate, although this waste slightly worsened both properties. RCWTB also increased the proportion of pores between 100 and 250 nm in size, which increased total and capillary effective porosities to maximum values of 13.54% and 13.51%, respectively, and sharply decreased the compression-related mechanical properties of concrete. Capillary effective porosity included the porosity effect of balsa-wood particles on concrete mechanical performance, so it allowed estimating the compression-related mechanical properties with a deviation lower than ±10%.This research work was supported by the Spanish Ministry of Universities within the framework of the State Program for the Promotion of Talent and Employability in R + D + i, State Mobility Subprogram, of the State Plan for Scientific and Technical Research and Innovation 2021–2023 [CAS22/00013]; MICINN, AEI, EU, ERDF and NextGenerationEU/PRTR [grant numbers PID2020-113837RB-I00; PID2023-146642OB-I00; 10.13039/501100011033; TED2021-129715B–I00]; the Junta de Castilla y León (Regional Government) and ERDF [grant number UIC-231; BU033P23]; the University of Burgos [grant number SUCONS, Y135.GI]; and, finally, the University of Padova
Analysis of raw-crushed wind-turbine blade as an overall concrete addition: Stress–strain and deflection performance effects
No full textEnd-of-life wind-turbine blades undergo non-selective crushing to produce Raw-Crushed Wind-Turbine Blade (RCWTB), which can be recycled as a raw material in concrete. RCWTB contains fibers from glass fiber-reinforced polymer that can add ductility and load-bearing capacity to concrete. Concrete mixes with percentage additions of between 0.0 % and 6.0 % RCWTB by volume are produced to analyze their compressive stress–strain performance, their deflection under bending forces, and their deformability under indirect-tensile stresses. Higher RCWTB contents increased deformability in the longitudinal direction under compression, the concrete material absorbing energy levels that were up to 111.4 % higher, even though additions of only 6.0 % RCWTB were sufficient to strengthen the load-bearing capacity. RCWTB fiber stitching effect was most noticeable in the transverse direction under compression, as it reduced elastic deformability and failure strain, removed the yield step caused by vertical-splitting cracking, and increased the fracture strain by up to 94.4 %. With regard to deflection, RCWTB fibers conditioned concrete compliance at advanced ages without any dependence on the modulus of elasticity, and percentage additions from 3.0 % provided load-bearing capacity. This advantage was also noted in indirect-tensile stresses for 6.0 % RCWTB. In summary, RCWTB successfully increased the ductility and load-bearing capacity of concrete per unit strength and carbon footprint.This research work was supported by the Spanish Ministry of Universities within the framework of the State Program for the Promotion of Talent and its Employability in the R + D + i, State Mobility Subprogram of the State Plan for Scientific and Technical Research and Innovation 2021-2023 [CAS22/00013]; MICINN, AEI, EU, ERDF and NextGenerationEU/PRTR [grant numbers PID2020-113837RB-I00; PID2023-146642OB-I00; 10.13039/501100011033; TED2021-129715B-I00; FPU21/04364]; the Junta de Castilla y León (Regional Government) and ERDF [grant number UIC-231; BU033P23; BU066-22]; the University of Burgos [grant number SUCONS, Y135.GI]; and, finally, the University of Padova
Fiber-Reinforced concrete and its life cycle assessment: A systematic review
No full textConcrete is the most environmentally demanding construction material in use worldwide, so evaluating the sustainability performance of concrete is therefore essential. Fiber-Reinforced Concrete (FRC) can diminish the carbon footprint of concrete, being verified by Life Cycle Assessment (LCA). In this systematic review, using the preferred reporting items for systematic reviews and meta-analyses, 69 documents were studied to survey the existing literature on FRC, its LCA methodology and results, and the mechanical performance of the mixes. The results were then presented, and the fibers were characterized, to analyze both the environmental and mechanical performance of the selected research papers using representative indexes, mostly regarding Global Warming Potential (GWP). These indexes showed that the environmental impacts of the FRC mixes could be reduced, even reaching reductions in the GWP of FRC of up to 94 %, without hindering their mechanical performance. FRC sustainability was highly dependent upon the nature and treatment of the used fibers. Thus, steel or synthetic fibers were the most common, yet the most polluting to produce, while some recycled fibers reached high environmental impacts due to the necessary treatments to obtain adequate characteristics, as their non-optimized production procedures can result in up to 7 % increase of GWP of FRC despite of the incorporation of these sustainable raw materials. Nevertheless, those FRC mixes achieved promising LCA results, even diving by half their GWP, when these treatments and procedures were carefully designed. Further development of concrete manufacturing processes and sustainable fiber recovery and characterization are also needed for successful implementation of greener solutions.This research work was supported by the Spanish Ministry of Universities, MICINN, AEI, EU, ERDF and NextGenerationEU/PRTR [grant numbers PID2020-113837RB-I00; 10.13039/501100011033; TED2021-129715 B–I00; PID2023-146642OB-I00; FPU21/04364]; the Junta de Castilla y León (Regional Government) and ERDF [grant number UIC-231; BU033P23; BU066-22]; and, finally, the University of Burgos [grant number SUCONS, Y135.
