Comparative evaluation of bioactive cements on biomimetic remineralization of dentin
2020
Background This study was designed to quantitatively compare the presence of apatite peaks on demineralized dentin to induced bio-mimetically by bioactive commercial materials. Material and methods Dentin slice specimens (n=6) were prepared and demineralized by by17% EDTA for 2 hours. Each disks materials (Theracal, Biodentine, CPP-ACP) were freshly prepared and was maintained in close contact with a demineralized dentin specimen immersed in PBS solution during one week. To evaluation of bioactivity, cements disks (n=6) were prepared from each material and immersed in PBS solution for one week. The bioactivity and remineralization ability was evaluated using FTIR spectroscopy and Scanning E…
Nutritional Profiling and the Value of Processing By-Products from Gilthead Sea Bream (Sparus aurata)
2020
Fish processing industries generate a large volume of discards. In order to fulfil with the principles of a sustainable circular economy, it is necessary to maintain aquaculture by-products in the food chain through the production of high-value biomolecules that can be used as novel ingredients. In this study, we try to give value to the gilthead sea bream by-products, evaluating the composition and the nutritional value of the muscle and six discards commonly obtained from the fish processing industry (fishbone, gills, guts, heads, liver, and skin), which represent ≈ 61% of the whole fish. Significant differences were detected among muscle and by-products for fatty acid and amino acid prof…
Role of biological control agents and physical treatments in maintaining the quality of fresh and minimally-processed fruit and vegetables
2019
International audience; Fruit and vegetables are an important part of human diets and provide multiple health benefits. However, due to the short shelf-life of fresh and minimally-processed fruit and vegetables, significant losses occur throughout the food distribution chain. Shelf-life extension requires preserving both the quality and safety of food products. The quality of fruit and vegetables, either fresh or fresh-cut, depends on many factors and can be determined by analytical or sensory evaluation methods. Among the various technologies used to maintain the quality and increase shelf-life of fresh and minimally-processed fruit and vegetables, biological control is a promising approac…
Aplicabilidad y percepción de utilidad del European Quality Instrument for Health Promotion (EQUIHP) en un programa de promoción de la salud
2018
Resumen Objetivo: Describir los resultados de la aplicación del European Quality Instrument for Health Promotion (EQUIHP) en el Programa MIH salud y la percepción de su utilidad por el equipo ejecutor de este. Método: Estudio de evaluación aplicando EQUIHP a un programa de promoción de la salud. Autocumplimentación de EQUIHP por ocho mujeres y dos hombres del equipo MIH salud, y realización de dos entrevistas grupales con este equipo sobre la percepción de su utilidad. Resultados: El programa ha obtenido una puntuación global de calidad de 6,5 sobre 10. EQUIPH ha permitido identificar los aspectos más débiles dentro del programa, como la falta de un plan de comunicación y las propias evalua…
Validación de un instrumento de evaluación del comportamiento sexual de personas con discapacidad intelectual para padres (ECS-PA)
2019
La reciente normalización de la sexualidad y de los derechos sexuales entre las personas con Discapacidad Intelectual (DI) ha hecho que se incremente el número de iniciativas dirigidas a mejorar sus conocimientos y habilidades mediante programas de educación afectivo-sexual pero dichos programas requieren instrumentos de evaluación fiables que permitan identificar sus necesidades y puedan ser sensibles al cambio tras la intervención. En dicha valoración deben confluir sus percepciones, las de los profesionales que se ocupan de ellos y las de sus padres para asegurar la veracidad de la información obtenida, pero lamentablemente carecemos de instrumentos psicométricos válidos y fiables tanto …
How online reviews of destination responsibility influence tourists’ evaluations: an exploratory study of mountain tourism
2019
This study examines how online reviews of the economic, sociocultural and environmental dimensions of tourism destination responsibility (TDR) influence tourists’ evaluations. The effects of these ...
Relationships among residents' image, evaluation of the stay and post-purchase behaviour
2005
Scholars have approached the analysis of the host community from a supply perspective rather than a demand one. This paper focuses on the study of residents when acting as tourists in their own region. In this sense, the present work aims to fill the gap existing in the literature about residents' tourist behaviour, analysing the influence of the image of their province on their evaluation of their travel experience and their future behaviour intentions. To accomplish this objective, a path analysis is carried out to test jointly the set of relationships among image, perceived quality, satisfaction, intention to return and willingness to recommend.
Efectos organizacionales y activacionales de la testosterona sobre la asunción de riesgos en conductas económicas: una revisión sistemática
2017
Resumen El objetivo de esta revision sistematica es evaluar la influencia de la testosterona circulante (efectos activacionales) y de la exposicion prenatal a ella (efectos organizacionales) sobre la asuncion de riesgos en conductas economicas, evaluando los trabajos de investigacion existentes hasta la fecha acerca de la tematica. La base bibliografica analizada se obtuvo de distintas bases de datos especializadas en el ambito de la psicologia y las neurociencias. Los resultados obtenidos concluyen en una relacion contrastada entre la testosterona circulante y la asuncion de riesgo financiero. En lo referente a la exposicion prenatal se evidencia un estado inmaduro de la investigacion sobr…
Attention-based Model for Evaluating the Complexity of Sentences in English Language
2020
The automation of text complexity evaluation (ATCE) is an emerging problem which has been tackled by means of different methodologies. We present an effective deep learning- based solution which leverages both Recurrent Neural and the Attention mechanism. The developed system is capable of classifying sentences written in the English language by analysing their syntactical and lexical complexity. An accurate test phase has been carried out, and the system has been compared with a baseline tool based on the Support Vector Machine. This paper represents an extension of a previous deep learning model, which allows showing the suitability of Neural Networks to evaluate sentence complexity in tw…
Deep neural attention-based model for the evaluation of italian sentences complexity
2020
In this paper, the Automatic Text Complexity Evaluation problem is modeled as a binary classification task tackled by a Neural Network based system. It exploits Recurrent Neural Units and the Attention mechanism to measure the complexity of sentences written in the Italian language. An accurate test phase has been carried out, and the system has been compared with state-of-art tools that tackle the same problem. The computed performances proof the model suitability to evaluate sentence complexity improving the results achieved by other state-of-the-art systems.
