Validación y propiedades psicométricas del “Cuestionario de valores de vida” (VLQ) para población española
No full textEl objetivo de este trabajo es presentar la adaptación española del
“Cuestionario de valores de vida” (VLQ; Wilson et al., 2010), aportando datos
sobre sus propiedades psicométricas. Se aplicó el cuestionario a 531 participantes
de entre 18 y 70 años (M= 28,73), siendo el 70% mujeres universitarias. El análisis
factorial exploratorio mostró tres factores principales: comunidad, cercanía y
obligaciones, cuyos niveles de consistencia interna fueron de 0,70, 0,71 y 0,68,
respectivamente, mientras que para la puntuación total fue de 0,71 que resultaron
similares a los del original. En cuanto a la validez concurrente, el VLQ mostró
correlaciones moderadas con el “Cuestionario de valores personales” (Schwartz,
1992) (r= 0,47) y con el “Cuestionario de instantánea vital” (Ruiz-García et al.,
2021; Tsai et al., 2023) (r= 0,65). Se discute la utilidad del VLQ para evaluar y hacer
seguimiento a los procesos clave involucrados en los cambios clínicos, así como
para mejorar y evaluar los valores personales íntimamente relacionados con la
calidad de vida, el sentido de la vida y el bienestar de la comunidad.The aim of this paper is to present the Spanish adaptation of the “Life Values
Questionnaire” (VLQ; Wilson et al., 2010), providing data on its psychometric
properties. The questionnaire was administrated to 531 participants aged between
18 and 70 years (M= 28.73), 70% of whom were female university students. The
exploratory factor analysis showed three main factors: community, closeness and
obligations, whose internal consistency levels were .70, .71 and .68, respectively,
while the total score was .71, which was similar to that of the English original
version. In terms of the concurrent validity, the VLQ showed moderate correlations
with the “Personal Values Questionnaire” (Schwartz, 1992) (r= .47), and with the
“Life Snapshot Questionnaire (Ruiz-García et al., 2021; Tsai et al., 2023) (r= .65).
The usefulness of the VLQ for assessing and tracking key processes involved in
clinical change, as well as for enhancing and assessing personal values intimately
related to quality of life, meaning in life and community well-being is discussed

White Wine Pomace Mitigates Hyperglycemia-Induced Cell Damage and Oxidative Stress in Caco-2 Cells
No full textComunicación presentada en: The 4th International Electronic Conference on Foods 2023, durante los días 15-30 de octubre de forma online.Hyperglycemia is a significant risk factor in metabolic syndrome, contributing to the development of cardiovascular diseases and diabetes mellitus. Hyperglycemia increases ROS (reactive oxygen species) production via glucose oxidation and protein glycosylation, leading to cell damage. Our previous studies have highlighted the antioxidant properties of wine pomace products (wWPPs), a co-product of winemaking, and their ability to modulate oxidative stress. The objective of this study was to evaluate the protective effect of wWPPs against oxidative stress in hyperglycemic Caco-2 cells. They were treated with 1.5 μg GAE/mL of wWPP bioaccessible fractions, obtained from gastrointestinal digestion (WPGI) and colonic fermentation (WPF), under normoglycemic or hyperglycemic (35 mM glucose) conditions. After 24 h of treatment, cell viability, oxidative stress biomarkers and the expression of transcription factors and enzymes involved in cellular oxidation balance were evaluated. Hyperglycemia induced a 30% reduction in cell viability, which was restored to normoglycemic levels by WPF treatment. The bioaccessible fractions were able to counteract hyperglycemia-induced oxidative stress in intestinal cells, as evidenced by significant decreases in carbonyl groups and MDA levels (10 and 40%, respectively). Furthermore, hyperglycemia-induced NF-κB overexpression was also significantly reduced by WPGI and WPF pre-treatment (between 15 and 53%), modulating the redox activity. In conclusion, the bioaccessible fractions of wWPP, particularly WPF, demonstrated significant potential in mitigating hyperglycemia-induced oxidative stress and enhancing cell viability in Caco-2 cells.This research was funded by the Ministry of Science, Innovation and Universities, Spanish State Research Agency and the European Regional Development Fund (Project PGC2018-097113-B-I00)
Design Optimization of Self-compacting Concrete with Residues for Different Scenarios
No full textComunicación oral presentado en: Building for the Future: Durable, Sustainable, Resilient (fib symposium) 2023, celebrado en Estambul (Turquía) durante los días 5-7 de junio.There is a need to promote high performance and sustainable construction materials such as Self-Compacting Concrete (SCC) made from various wastes. In concrete manufacturing, there is a general tendency to worsen the workability and mechanical behavior when working with wastes instead of natural raw materials. It is therefore necessary to use multi-criteria algorithms to analyze the impact of using sustainable materials, and to balance the increase in sustainability with the deterioration of certain performances, such as flowability and strength. In addition, it is also necessary to include a cost analysis in the study, which allows us to find the most suitable products for varied real-life applications.
In this research, 19 SCC mixes have been manufactured, where conventional materials (CEM I, natural aggregates, and limestone filler) are progressively substituted by more sustainable ones (Ground Granulated Blast Furnace Slag -GGBFS- replacing cement, and Recycled Concrete Aggregate -RCA- in coarse, fine and filler sizes of the aggregate). The designed mixes are analyzed based on different criteria: mechanical criteria (flowability, compressive strength and modulus of elasticity), sustainability (carbon footprint) and cost. Five different scenarios are proposed for different priorities or situations, which are evaluated using three multi-criteria algorithms.
Some of the conclusions of the study show that coarse RCA and limestone fines perform adequately in most scenarios. Fine RCA rates above 50% were not recommended in any of the scenarios. A versatile design would be an SCC with RCA coarse aggregate, limestone fines, GGBFS and 0% fine RCA.This research work was supported by the Spanish Ministry of Universities, MICINN, AEI, EU, ERDF and NextGenerationEU [grant numbers PID2020-113837RB-I00; 10.13039/501100011033; TED2021-129715B-I00]; the Junta de Castilla y León (Regional Government) and ERDF [grant number UIC-231]; and the University of Burgos [grant number SUCONS, Y135.GI]
Una refundición moretiana de una comedia de Claramonte: El valiente justiciero y El rey don Pedro en Madrid
Get PDFAgustín Moreto is one of the most outstanding authors of our Golden Theatre, because he was, in addition to Calderón, the main exponent of a form of composition that, together with collaborative writing, constitutes one of the most common dramaturgical modalities among secular poets: the rewriting. In this sense, the dramatic production of Agustín Moreto includes numerous motifs and arguments that were already present in the previous theater, especially in that of Lope de Vega. However, he was not the only playwright whom he took as a model, because he also consulted works by authors such as Tirso de Molina, Mira de Amescua, Guillén de Castro or Andrés de Claramonte. This work presents a rewriting of Moreto, El valiente justiciero, which starts from a text by Andrés de Claramonte, El rey don Pedro en Madrid y el infanzón de Illescas. Throughout the article, the most prominent similarities and differences between both comedies will be analyzed and it will be shown that the technique used by Moreto in his rewritings is very similar regardless of who the author of the source comedy is.Agustín Moreto es uno de los autores más destacados de nuestro teatro áureo, ya que fue, además de Calderón, el principal exponente de una forma de composición que, junto con la escritura en colaboración, constituye una de las modalidades dramatúrgicas más habituales entre los poetas auriseculares: la reescritura. En este sentido, la producción dramática de Agustín Moreto recoge numerosos motivos y argumentos que ya estaban presentes en el teatro anterior, especialmente en el de Lope de Vega. No obstante, no fue el único dramaturgo al que tomó como modelo, ya que también consultó obras de autores como Tirso de Molina, Mira de Amescua, Guillén de Castro o Andrés de Claramonte. En este trabajo se presenta una refundición moretiana, El valiente justiciero, que parte de un texto de Andrés de Claramonte, El rey don Pedro en Madrid y el infanzón de Illescas. A lo largo del artículo se analizarán las similitudes y divergencias más destacadas entre ambas comedias y se demostrará que la técnica empleada por Moreto en sus refundiciones es muy similar independientemente de quién sea el autor de la comedia fuente.Open Access funding provided thanks to the CRUE-CSIC agreement with Springer Nature
Exploitation of indoor illumination for typical flat dwellings in the Mediterranean area
Get PDFThe 2018/844 Energy Performance of Buildings Directive (EU) has widened the scope of appropriate design of buildings from a pure energy performance and carbon emissions perspective to a wider scope that includes indoor comfort, and indoor air quality among others. To this effect, external parameters, especially solar energy, have a strong impact on the energy performance of buildings in Mediterranean regions, which requires careful consideration when it comes to benefiting from natural lighting while avoiding solar overheating. This paper addresses the considerations of natural lighting in the deep renovation of a housing block in the Mediterranean climate of the Republic of Malta, comparing some of the usual illuminance ranges to achieve optimal conditions based on international recommendations. DesignBuilder v7.0.0.102 has been the selected software to model the building that has been calibrated through experimental measurements. The model enabled the natural lighting conditions in the building evaluated and the effectiveness of suggested improvements to be determined. Results pointed out that the building under study satisfies the international standards about the prevention of visual discomfort only. Increasing the size of windows in identified zones, especially the first floor, was found to help improve other natural lighting characteristics. One of the proposed designs (Model 6) that replaces single-glazed with double-glazed windows that include an external spectrally-selective coating would significantly improve access to natural light bringing the building closer to the recommended levels of Annual Sunlight Exposure and reducing artificial lighting usage by up to five times. The relocation of room spaces could also reduce the use of artificial lighting.The Spanish Ministry of Science & Innovation (Ref.

Addressing Practical Use of Viologen-Derivatives in Redox Flow Batteries through Molecular Engineering
Get PDFIn practical scenarios, viologen-derivatives face an accelerated degradation in the unavoidable presence of traces of oxygen in large-scale redox flow batteries. Herein, we confirm the primary degradation mechanism and propose a straightforward, cheap, and fast method to evaluate the stability of viologen-derivatives toward this degradation. Considering that the cleavage of the N-substituent is the main proposed pathway for viologen degradation, a new viologen-derivative, bearing an alkylsulfonate chain with a secondary carbon center joined to the N atom, is synthesized to illustrate how molecular engineering can be used to improve stability.The authors acknowledge the financial support by the Spanish Government (Ministerio de Ciencia e Innovación, Grants PID2021-124974OB-C22 and PID2020-115789GB-C21) and Ramón y Cajal award (RYC2018-026086-I) as well as the MeBattery project.

Main anatomical characteristics of the hominin fossil humeri from the Sima de los Huesos Middle Pleistocene site, Sierra de Atapuerca, Burgos, Spain: An update
Get PDFSome of the Sima de los Huesos (SH) humeri have been previously studied and described elsewhere. Here we present an updated inventory and a review of the specimens recovered to the present day. The morphological key traits of the adult and subadult specimens are described, discussed, and illustrated. The SH humeri share with Neandertals many traits usually considered to be Neandertal specializations, thus, most of this morphological pattern is not exclusive to them. The variation found within fossil samples stresses the frequential nature of all these traits and in the specific case of the SH humeri, most of the traits considered as phylogenetically relevant are retained by their descendants, the Neandertals. Some traits are plesiomorphic for the entire genus Homo or are present in European hominins since the early Pleistocene. Finally, some other traits display high variability within the SH sample or different hominin samples and are of uncertain phylogenetic value. Altogether, this evidence is consistent with the hypothesis based on the overall cranial and postcranial morphology that the SH hominins are a sister group to the later Neandertals.The Atapuerca research project is financed by Ministerio de Ciencia, Innovación y Universidades grant number PID2021-122355NB-C31 financed by MCIN/AEI/10.13039/501100011033/FEDER, UE.

Valorization of brewer’s spent grain by furfural recovery/removal from subcritical water hydrolysates by pervaporation
Get PDFThis work is focused on the development of a sustainable process for the valorisation of the main by-product
generated in the brewing industry, the brewer’s spent grain (BSG). A two-step process combining subcritical
water treatment and pervaporation (PV) was proposed to hydrolyse the hemicelluloses fraction of this lignocellulosic biomass and further removal/recovery of some of the degradation products of sugars by using two
different organophilic membranes, polydimethylsiloxane (PDMS) and polyoctilmethylsiloxane (POMS) membranes. Specifically, furfural is the dehydration product of pentoses and it is one of the top biomass-based
chemicals being an important platform chemical. For synthetic binary mixtures, lower total permeation flux
but higher enrichment factors for furfural were determined for POMS. When dealing with subW hydrolysates,
POMS membranes yielded the highest furfural recovery, 94.1 %, with permeate concentrations as high as 40 g⋅L1
. Furthermore, it was assessed that PV is a suitable detoxification method that yielded a retentate nearly free of
furfural allowing its use as growth media in the opposite to the subW hydrolysate with inhibitory furfural
concentrations for microbial bioprocesses.This work was supported by the Agencia Estatal de Investigacion ´ [Grants No PID2019-104950RB-I00 / AEI / 10.13039/501100011033, TED2021-129311B-I00 and PDC2022-133443-I00] and the Junta de Castilla y Leon ´ (JCyL) and the European Regional Development Fund (ERDF) [grant number BU050P20].
