Desarrollo tecnológico para determinar de forma cuantitativa, durante el tratamiento alcalino en NaOH (cocido) de aceitunas verdes al estilo sevillano, el porcentaje de penetración de la sosa en la pulpa y predecir el momento óptimo para finalizar el proceso. El sistema combina un protocolo de toma de muestras y acondicionamiento del fruto (corte, marcado con fenolftaleína y captura de imagen con iluminación constante) con algoritmos de visión artificial que calculan el porcentaje de cocido. A partir de la serie temporal de medidas, un interpolador estima el instante en el que se alcanzará un umbral objetivo (p.ej., 2/3 o 3/4 de penetración). Incluye además una aplicación web para gestión y trazabilidad del proceso (cloud computing) y evidencia de implantación industrial (TRL 9)., Estructura principal: - Cocido_aceitunas.docx: memoria descriptiva del desarrollo tecnológico (objetivo, descripción, impacto, evidencias). - Cocido Aceitunas.pptx: presentación técnica (metodología y resultados de ensayos). - Patente/3_ES-2394821_B2.pdf: patente antecedente (OEPM) ES-2394821 B2. - Contrato/CONTRATO.pdf: evidencia contractual FIUS–Pymesuma S.L.

There is vast amount of research that links implicit theories of intelligence with several learning-relevant variables in both learners and teachers alike. However, there is a gap in the literature, as there is almost no research done with university teachers. Furthermore, most scientific research polarizes incremental and fixed views of intelligence in spite of data that show there is heterogeneity in participants’ views. This study explores the implicit theories of intelligence of university teachers. The sample comprised 20 university teachers (10 men and 10 women) from the University of Seville. Four participants were selected from each field of knowledge, according to the category system in place at the university in question, namely: Arts and Humanities (A&H), Sciences (S), Health Sciences (HS), Social and Legal Sciences (S&LS), and Engineering and Architecture (E&A). Also, the selection process ensured that half the participants had less than 15 years' teaching experience at the university and the other half more than 15 years' experience. A semi-structured interview called "Views on Intelligence within the Educational Field" was designed. Participants were asked to express their opinión about several small vignettes regarding intelligence. The instrument comprises short cases or vignettes, highlighting different dimensions of intelligence. We identified 12 relevant dimensions in which a view on intelligence could be expressed and contextualized. They were: Control, Heredity, Effort, Culture, Training, Critical Period, Context, Expectations, Associated Qualities, People, Gender, and Diversity of Intelligence. Data from interviews were analysed employing a category system designed to capture heterogeneity. The utterances were segmented and analyzed using a coding manual. From the units of meaning extracted from the participant’s responses, we constructed 116 different categories related to intelligence. These categories were later organized into 18 different topics, as several themes arose from the interviews. These topics were: Effort, Genetic Influence, Development in Non-Specific Terms, Global Environment, Formal Education, Culture, Activities, Teacher Influence, Parental Influence, Developmental Characteristics, Motivational and Emotional Influence, Others’ Expectations Influence, Own Expectations Influence, Other Personal Characteristics Influence, Characteristics Associated to Intelligent People, Gender, Presence of Intelligence in Activities Outside Academic Fields, and Social and Emotional Intelligence. Finally, an upper-level hierarchical categorization was developed, where different categories were put together taking into account different criteria in order to obtain global results. These categories are Global Influences of Change (all categories that relate to modifiability of the intelligence), Specific Influences of Change (all categories that expresses the relation of something specific on intelligence), Non-Specific Influences of Change (all categories that expresses that intelligence can or cannot be modified, but not telling how), Individual Influences of Change (all categories related to the individual’s actions and characteristics linked to intelligence malleability), Environmental Influences of Change (all categories related to the environment that may or may not affect the development of intelligence), and Total Genetic Influence (all categories related to genetic influence)., - Base de Datos Concepciones de Inteligencia - Manual de Codificación Concepciones de Inteligencia

Post-translational modifications and naturally occurring mutations of cytochrome c have been recognized as a regulatory mechanism to control its biology. In this work, we investigate the effect of such in vivo chemical modifications of human cytochrome c on its redox properties in the adsorbed state onto an electrode. In particular, tyrosines 48 and 97 have been replaced by the non-canonical amino acid p-carboxymethyl-L-phenylalanine (pCMF), thus mimicking tyrosine phosphorylation. Additionally, tyrosine 48 has been replaced by a histidine producing the natural Y48H pathogenic mutant. Thermodynamics and kinetics of the interfacial electron transfer of wild-type cytochrome c and herein produced variants, adsorbed electrostatically under different local interfacial electric fields, were determined by means of variable temperature cyclic film voltammetry. It is shown that non-native cytochrome c variants immobilized under a low interfacial electric field display redox thermodynamics and kinetics similar to those of wild-type cytochrome c. However, upon increasing the strength of the electric field, the redox thermodynamics and kinetics of the modified proteins markedly differ from those of the wild-type species. The mutations promote stabilization of the oxidized form and a significant increase in the activation enthalpy values that can be ascribed to a subtle distortion of the heme cofactor and/or difference of the amino acid rearrangements rather than to a coarse protein structural change. Overall, these results point to a combined effect of the single point mutations at positions 48 and 97 and the strength of electrostatic binding on the regulatory mechanism of mitochondrial membrane activity, when acting as a redox shuttle protein., File name: Otras-figuras_Ms_BBA-Bioenergetics.docx Description: A Word file with the figure images File name: Raw_data.zip Description: .nox files with the raw data of voltammetry File name: Fig_2+3+6.jnb Description: A sigmaplot file with figures 2+3+6 File name: Fig_5.jnb Description: A sigmaplot file with figure 5

Surface reconstituted metal-organic frameworks (MOFs) offer appealing properties for electrocatalysis due to their unique structural and compositional advantages. In this work, a controlled potential-induced reconstruction of a two-dimensional cobalt metal-organic framework for boosting oxygen evolution reaction in alkaline media is reported. The current MOF is shown to undergo a partial structural transformation that generates a heterogeneous system, where the original MOF coexists with an oxyhydroxide phase. In fact, the potential-induced stabilization of Co(III) metal centers in the MOF is crucial for delaying its full degradation in alkaline media. This partial retention of the Co(III)MOF phase in the so-derived heterogeneous catalyst has been demonstrated to be decisive for boosting the alkaline electrocatalytic oxygen evolution reaction (OER), displaying superior OER activity in terms of both thermodynamic and kinetic merits compared to the benchmark IrO2 and RuO2 electrocatalysts and the prototypical cobalt (oxy)hydroxides, with a Tafel slope of 52 mV dec−1 and a turnover frequency (TOF) of 6.8 s−1 at 450 mV. Remarkably, the generated final product is stable, exhibiting high robustness and long durability for long-term OER electrolysis. This work provides new insight into the impact of the reconstruction of a MOF for alkaline OER under typical electrochemical conditions, which ultimately benefits the rational design of MOF-based catalysts with high electrocatalytic activity for oxidation reactions., File name: Otras-figuras_Ms_Catalysis-today.docx Description: A Word file with the figure images File name: Raw_data.zip Description: .nox files with the raw data of voltammetry File name: Fig_4.jnb Description: A sigmaplot file with figure 4.
