The anthropological function of dialogue in political reconciliation processes: ethical analysis of Ignacio Ellacuría's thought on the 25th anniversary of his death (1989-2014)
The idea of a just and lasting peace seems to be unachievable when people are suffering a civil or international war, a violent revolutionary process or a dictatorship, or when they are immersed in a long period of structural ...
The primeval optical evolving matter by optical binding inside and outside the photon beam
Optical binding has recently gained considerable attention because it enables the light-induced assembly of many-body systems; however, this phenomenon has only been described between directly irradiated particles. Here, ...
Comparación entre diferentes procedimientos de ajuste de controladores PID. II. Márgenes de ganancia y de fase y comportamiento como regulador
La doble normalización (ganancia y tiempo) de los procesos de primer orden con tiempo muerto (First Order Plus Dead Time, FOPDT) permite el análisis sistemático de la respuesta dinámica de los sistemas controlados, por lo ...
Identificación de las principales competencias necesarias para el uso profesional de la estadística aplicada en ADE
El objetivo de este trabajo es determinar las competencias para el uso profesional de la Estadística que son más valoradas para optar a un puesto de trabajo. Para ello se ha utilizado una metodología de triangulación basada ...
Screening of ionic liquids and deep eutectic solvents for physical CO2 absorption by soft-SAFT using key performance indicators
The efficient screening of solvents for CO2 capture requires a reliable and robust equation of state to characterize and compare their thermophysical behavior for the desired application. In this work, the potentiality of ...
The external didactic transposition of mathematics at university level: dilemmas and challenges
We develop the idea that research on university mathematics education needs to more systematically address the external didactic transposition. After outlining existing research that goes more or less in this direction, ...
Reference epistemological model: what form and function in school institutions?
Many teaching problems are related with the lack in the school institutions of epistemological tools to design, manage and evaluate study processes. We propose to include within these tools the question-answer maps as a ...
Serotype-specific detection of dengue viruses in a nonstructural protein 1-based enzyme-linked immunosorbent assay validated with a multinational cohort
Background Dengue virus (DENV) infections pose one of the largest global barriers to human health. The four serotypes (DENV 1–4) present different symptoms and influence immune response to subsequent DENV infections, ...
Simulación de procesos con controladores lógico-programables (PLC’s)
La realización de prácticas en el laboratorio de control de procesos presenta como mayor dificultad el coste asociado al funcionamiento del proceso, debido al consumo de reactivos, de energía o a la generación de residuos. ...
An online course to teach ATD research praxeologies: The ICMI awardees multimedia online resources
We present some of the main elements of a project of Multimedia Online Resource addressed to international researchers willing to be initiated in the ATD. The project was launched by the executive committee of the International ...
Unconventional Optical Matter of Hybrid Metal–Dielectric Nanoparticles at Interfaces
Optical matter, a transient arrangement formed by the interaction of light with micro/nanoscale objects, provides responsive and highly tunable materials that allow for controlling and manipulating light and/or matter. A ...
Synthesis, Magnetic, and Photocatalytic Activity of Polypyrrole-Based TiO2–Fe Catalyst for Wastewater Treatment
The primary aim of this study is to investigate the degradation efficacy of the Ppy/TiO2-Fe photocatalyst for MB dye in an aqueous solution. Firstly, the direct addition of TiO2 and Fe was done to prepare Ppy/TiO2-Fe ...
El problema didáctico del álgebra elemental: Un análisis macro-ecológico desde la teoría antropológica de lo didáctico
Presentamos una visión global, sintética y actualizada de las aportaciones realizadas por la teoría antropológica de lo didáctico al problema de la enseñanza del álgebra elemental. Partimos de los primeros resultados ...
Different mechanisms that promote protein monoubiquitination
Protein monoubiquitination is a post-translational modification that consists of the conjugation of a single ubiquitin molecule to a target protein residue. Monoubiquitination regulates protein activity and localization ...
Un modèle épistémologique de référence pour la recherche sur l’algèbre élémentaire
La théorie anthropologique du didactique attribue un rôle déterminant au questionnement du savoir mathématique et propose comme outil d’analyse l’élaboration de modèles épistémologiques de référence (MER). Nous présentons ...
An overview of “bridging courses” from the ATD perspective
The presence of bridging courses in the European university panorama has evolved from a simple spontaneous proposal to being part of a consolidated resource for new students in many universities. In Spain, the tendency ...
Accurate and model-free control function for a single stage transcritical refrigerator cycle
Transcritical cycles are a successful and probed system in engineering practices, particularly in refrigeration. Therefore, their optimization is a critical factor in the design, control, and operation in order to maximize ...
Glycogenin is dispensable for normal liver glycogen metabolism and body glucose homeostasis
Glycogen is a glucose-storage polysaccharide molecule present in animals, fungi and bacteria. The enzyme glycogenin can self-glycosylate, forming an oligosaccharide chain that primes glycogen synthesis. This priming role ...
Application of flow cytometry analysis to elucidate the impact of scale-down conditions in Escherichia coli cultivations
In homogeneities appear in large-scale fed-batch bioprocesses; especially when the distribution of the feeding solution and of the oxygen is uneven. In order to study the consequences of these heterogenic conditions on the ...
Active Glycogen Synthase in the Liver Prevents High-Fat Diet-Induced Glucose Intolerance, Decreases Food Intake, and Lowers Body Weight
Many lines of evidence demonstrate a correlation between liver glycogen content and food intake. We previously demonstrated that mice overexpressing protein targeting to glycogen (PTG) specifically in the liver—which have ...
