Análisis preliminar de las tobas cuaternarias del río Ebrón (Castielfabib, Valencia, Cordillera Ibérica)

In this paper the Alpine cleavage affecting the Permo-Triassic series of the Espadan Range (Castellón) is studied. Cleavage affects to argillites and sandstones in Saxonian and Buntsandstein facies. At cartographic scale it is linked with the Espadan box anticline with constant ONO-ESE trend. At microscoscopic scale it constitutes a “spaced cleavage” with a predominance of pressure solution and passive rotation mechanisms. At outcrop scale the cleavage characterizes by a sigmoidal geometry linked both the post-cleavage flexural slip as a cleavage-related flexural flow mechanism. The proposed kinematic model to explain its origin includes three main stages: 1) incipient development of cleavage linked to layer-parallel shortening, 2) buckling and increasing of cleavage penetrativity and 3) folfing amplification and layer-parallel shear. RESUMEN Se estudia la esquistosidad alpina que afecta a la serie Permo-Triásica de la Sierra de Espadán, (Castellón). La esquistosidad afecta a los tramos argilíticos y areniscosos en facies Saxoniense y Buntsandstein, con distinto grado de penetratividad. A escala cartográfica se asocia al anticlinal de Espadán con geometría en cofre y orientación ONO-ESE. A escala microestructural se clasifica como esquistosidad espaciada con predominio de los mecanismos de disolución por presión y rotación mecánica de filosilicatos. A escala de afloramiento destaca la geometría sigmoidal de las superficies de esquistosidad atribuida tanto a un mecanismo post-esquistoso de flexodeslizamiento en las capas competentes como a flexofluencia sin-esquistosa en capas incompetentes. El modelo cinemático para su génesis contempla tres estadios: 1) desarrollo incipiente de esquistosidad en relación a acortamiento paralelo a las capas, 2) buckling e incremento del grado de penetratividad y 3) amplificación de los pliegues y cizalla simple paralela a las capa

Evaluation of rice straw ash as a pozzolanic addition in cementitious mixtures

[EN] Rice husk ash is one of the most widely studied biomass ashes used in pozzolanic addition. Given its lower silica content, rice straw ash (RSA) has been explored less often, despite the fact that, according to the United Nations Food and Agriculture Organization (FAO), rice straw (RS) production is estimated at 600 million tons/year. In this work, RSA was physically and chemically characterized, and its pozzolanic properties were assessed. A controlled conditioning, burning, homogenization and grinding procedure was carried out to obtain RSA from RS. Chemical composition, insoluble residue, reactive silica, chloride content and particle size distribution were assessed for ash characterization. To determine RSA pozzolanicity, Frattini, electrical conductivity and pH measurements in an aqueous suspension of hydrated CH/RSA mixtures were obtained. Portland cement (PC) mortars with 15% and 30% RSA substitutions evaluated. The mechanical tests showed specimens with a strength activity index up to 90% and 80% with 15% and 30% RSA, respectively, after 3 days, and these values grew to 107¿109% after 90 curing daysThis research was funded by the Spanish Government and FEDER funds (MINECO/FEDER-Project RTI2018-09612-B-C21).Hidalgo, S.; Soriano Martinez, L.; Monzó Balbuena, JM.; Paya Bernabeu, JJ.; Font, A.; Borrachero Rosado, MV.

Promoción de parentalidad positiva en Polígono Sur. Diseño de un programa para familias en situación de riesgo psicosocial

Las recomendaciones nacionales e internacionales en materia de promoción de parentalidad positiva reconocen la necesidad de apoyar a las familias para un ejercicio adecuado de sus funciones educativas, particularmente a aquellas que se encuentran situaciones de riesgo psicosocial. Estas recomendaciones sitúan a los servicios municipales como las instituciones idóneas para garantizar dicho apoyo. En este trabajo se presenta el Programa de Promoción de Parentalidad Positiva en Polígono Sur (5P’s), una iniciativa de carácter psicoeducativo y comunitario que surge, fundamentalmente, por la necesidad de disponer de materiales y recursos específicos para familias que, por su situación de particular vulnerabilidad, por sus propios valores culturales, así como por las particularidades del barrio en el que habitan (una zona de necesidad de transformación social), no se beneficiarían de otros programas ya existentes. A lo largo de este trabajo se describen los contenidos del programa, su estructura y el diseño de evaluación previsto y se discuten sus fortalezas y retos futuros.Both national and international recommendations on positive parenting recognize the need for supporting families in their childrearing tasks, particularly in psychosocial-risk situations. These recommendations highlight local services as the best source to support families. In this paper, the Program for Promoting Positive Parenting in Polígono Sur (5P’s) is described. 5P’s is a psycho-educational and community initiative starting from the need for specific materials for vulnerable families because of: (1) their psychosocial profile, (2) their cultural values; (3) living in a neighborhood with at-risk conditions. The contents, the format and the evaluation design of the program are introduced. Strengths and future challenges are discussed

Role of age and comorbidities in mortality of patients with infective endocarditis

[Purpose]: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. [Methods]: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. [Results]: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39–1.88),and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. [Conclusion]: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group

Olive pomace oil improves the oxidative stability and nutritional value of oil-based cakes with anise essence, a traditional confectionery product in Spain

8 Páginas.-- 3 Figuras.-- 2 TablasRefined olive pomace oil (OPO) was studied as an alternative to sunflower oil (SO) in oil-based cakes with anise essence, a traditional confectionery baked product in Spain. Partial and total oil replacements in cakes obtained at an industrial level were evaluated. The influence of processing and storage on the oxidation extent and the contents of oil bioactive components was investigated. Results showed a low oxidative impact of the processing, which was significantly lower for OPO. Oxidation was however considerably high in SO at the end of the shelf-life (6 months), presenting peroxide values higher than 150 meq/kg oil, and very low in OPO, with peroxides close to the limit for fresh refined oils (5 meq/kg). Oil blends containing 25 or 50 wt% OPO exhibited intermediate results. Bioactive oil components practically remained unchanged in the processing, but significant losses of α-tocopherol were detected after 6-month storage, with 30–50% losses for SO and ∼15% for OPO. The levels of squalene also remained high in OPO (90%) and no significant changes were found for sterols, triterpenic alcohols or triterpenic acids. A consumer panel test showed no differences between the fresh samples, but clear preferences for the new OPO-containing products were found during storage.This work was funded by ORIVA through project with reference 20214171 and by MCIN/AEI/10.13039/501100011033 through project with reference PID2020-119304RB-I00.Peer reviewe
