La interpretación cinematográfica como invariante genérica
2002
El objetivo de este artículo es mostrar cómo el análisis de la interpretación actoral cinematográfica puede contribuir a la comprensión de las películas y a la del género al que se adscriben, porque la interpretación puede ser considerada como una invariante genérica, es decir, si se quiere definir un género cinematográfico se debería estudiar, aparte de otros elementos, el modelo específico de interpretación y sus papeles particulares.
The moderator effect of sex on attitude toward communication, emotional intelligence, and empathy in the nursing field
2017
Objectives: to analyze differences in the variables for the object of this study (attitude toward communication, emotional intelligence, and empathy) according to sex; verify correlations among variables between men and women and analyze regression models according to sex. Method: the ATC was used to measure attitudes toward communication; the Jefferson Scale of Empathy was used to measure empathy; and the Trait Meta Mood Scale 24 was used to measure emotional intelligence. The sample was composed of 450 nurses working in 7 hospitals located in Valencia, Spain. The t-test for independent samples was used to verify whether there were statistically significant differences, together with a pri…
Valoración, afrontamiento y ansiedad a la hora de dejar de fumar
2010
El objetivo de este estudio consiste en analizar la valoración (appraisal) cognitiva y los tipos de afrontamiento que adoptan las personas a la hora de dejar de fumar. El instrumento de evaluación utilizado en una muestra de 107 estudiantes es el Inventario de Valoración y Afrontamiento (IVA), diseñado a partir del modelo de la valoración de Lazarus y Folkman (1986). El IVA consta de tres subescalas de valoración (amenaza, desafío e irrelevante) y seis subescalas de afrontamiento (cognitivo y conductual-motor dirigido a cambiar la situación, cognitivo y conductual-motor dirigido a reducir la emoción, pasivo y evitativo). Los resultados, señalan que cuando las personas realizan una valoració…
Application of pulsed electric fields in meat and fish processing industries: An overview.
2019
The market demand for new meat and fish products with enhanced physicochemical and nutritional properties attracted the interest of the food industry and academia to investigate innovative processing approaches such as pulsed electric fields (PEF). PEF is an emerging technology based on the application of electrical currents between two electrodes thus inducing electroporation phenomena and enabling a non-invasive modification of the tissues' structure. This review provides an overview of the current knowledge on the use of PEF processing in meat and fish to enhance the physicochemical and nutritional changes, as a preservation method, as well as for improving the extraction of high added-v…
The role of the Nature of Science in citizens' education
2007
O presente trabalho tem como propósito dar uma nova contribuição para o debate que se vem desenvolvendo, já faz algum tempo, em volta do papel da natureza da ciência na educação científica e, em particular, na formação de uma cidadania para a participação na tomada de decisões. This paper aims to contribute to the debate on the role of the nature of science and technology in science education, paying particular attention to preparing citizens to participate in decision making.
A Teaching proposal for the study of eigenvectors and eigenvalues
2017
[EN] In this work, we present a teaching proposal which emphasizes on visualization and physical applications in the study of eigenvectors and eigenvalues. These concepts are introduced using the notion of the moment of inertia of a rigid body and the GeoGebra software. The proposal was motivated after observing students¿ difficulties when treating eigenvectors and eigenvalues from a geometric point of view. It was designed following a particular sequence of activities with the schema: exploration, introduction of concepts, structuring of knowledge and application, and considering the three worlds of mathematical thinking provided by Tall: embodied, symbolic and formal.

Valorization of Wastewater from Table Olives: NMR Identification of Antioxidant Phenolic Fraction and Microwave Single-Phase Reaction of Sugary Fract…
2021
The table olive industry is producing a huge amount of wastewater, which is a post-processing cost and an environmental concern. The present study aims to valorize this processing by-product to obtain a value-added product, thereby enhancing resource efficiency and contributing to achieving sustainable development goals (SDGs). In this sense, a chemical reaction-based platform was developed to obtain valuable components, such as levulinic acid (LA) and 5-hydromethylfurfural (HMF). The products were then analyzed using NMR identification of the antioxidant phenolic fraction and microwave single-phase reaction of the sugary fraction. According to the results, the highest concentration of phen…
Estudio del análisis de frecuencia de resonancia tras la colocación de 133 implantes dentales
2006
Introducción: La estabilidad primaria del implante dental está relacionada con el hueso que se encuentra en contacto con él y se puede medir mediante el análisis de frecuencia de resonancia. Material y métodos: En 133 implantes (62 en maxilar y 71 en mandíbula) se midió la frecuencia de resonancia y la fuerza de inserción para conocer la estabilidad de los implantes el día de la cirugía, y estudiar su relación con distintas variables. Resultados: El cociente de estabilidad del implante obtenido el día de la cirugía fue de 62'1 y el de la fuerza de inserción fue de 35'7 Nw. La fuerza de inserción fue proporcional al análisis de la frecuencia de resonancia, a mayor fuerza de inserción mayor c…
