Principales resultados del estudio. Proyecto: ACCCES: Traducción, aplicación y análisis de la adaptación inicial del Cuestionario de Comportamientos …
2004
Este proyecto tiene como objetivo principal la adaptación del DBQ (Driving Behaviour Questionnaire) a la población de conductores españoles y la subsiguiente consecución de datos empíricos relativos al error humano en la conducción de vehículos en nuestro país. Las aportaciones esenciales resultantes del desarrollo de este proyecto de investigación pueden resumirse en dos categorías: (1) Desde un punto de vista instrumental, la adaptación a la población española del cuestionario DBQ, un instrumento internacionalmente reconocido y utilizado en la investigación en el campo de la seguridad vial. (2) Desde un punto de vista aplicado, la profundización en el conocimiento de las dimensiones condu…
¿Es posible implantar programas de prevención en el medio escolar?
2003
Los profesores de un centro de formación profesional específica, entendiendo que su trabajo no tiene otra meta que la educación integral, asumen en su trabajo la preven¬ción para dotar a los educandos con capacidades, recursos y habilidades para la toma de sanas decisiones.En este artículo explican cómo desarrollan esta acción preventiva, que entienden cons¬ciente, sistemática, organizada y participativa, señalando las implicaciones de su incor¬poración a la red de las escuelas promotoras de salud.
Construcción y validación de un sistema de detección precoz de trastornos de desarrollo (SDPTD) en niños de 18, 24, y 36 meses
2013
En esta tesis se pretende contruir una herramienta de detección precoz que detecte cualquier alteración que se produzca en el desarrollo del niño como una medida preventiva de posibles trastornos posteriores más graves. En esta investigación se ha diseñado una herramienta basada en web y apoyada en videos para facilitar a las familias la administración. El sistema esta compuesto de 7 cuestionarios pero en esta tesis estan validados los 3 cuestionarios (18 meses, 24 meses y 36 meses). Los cuestionarios se pueden encontrar en: https://cudap.uv.es/ProyectoC/
Effects of an incremental maximal endurance exercise stress-induced cortisol on cognitive performance
2019
Exercise; Cognitive functions; Cortisol Ejercicio físico; Funciones cognitivas; Cortisol Exercici físic; Funcions cognitives; Cortisol Objectives: It can be hypothesized that cognitive performance decreases after fatigue protocol when it coincides with the maximum peak of cortisol. The first aim of this study was to elucidate the effects of a single bout of high intensity exercise on behavioural (i.e., attention and memory) and physiological (i.e., salivary cortisol) responses. The second objective was to evaluate the effect of the performance of the cognitive tasks on cortisol levels. Methods: Thirty-four physically active men (at least 5 days/week of physical activity practice) 38.11 (1.5…
On the Detection of Distributed Roughness on Ball Bearings Via Stator Current Energy: Experimental Results

Transcranial direct current stimulation preconditioning modulates the effect of high-frequency repetitive transcranial magnetic stimulation in the hu…
2012
Experimental studies emphasize the importance of homeostatic plasticity as a mean of stabilizing the properties of neural circuits. In the present work we combined two techniques able to produce short-term (5-Hz repetitive transcranial magnetic stimulation, rTMS) and long-term (transcranial direct current stimulation, tDCS) effects on corticospinal excitability to evaluate whether and how the effects of 5-Hz rTMS can be tuned by tDCS preconditioning. Twelve healthy subjects participated in the study. Brief trains of 5-Hz rTMS were applied to the primary motor cortex at an intensity of 120% of the resting motor threshold, with recording of the electromyograph traces evoked by each stimulus o…

In this paper mathematical modeling of a vehicle crash test based on a single-mass is studied. The model under consideration consists of a single-mass coupled with a spring and/or a damper. The parameters for the spring and damper are obtained by analyzing the measured acceleration in the center of gravity of the vehicle during a crash. A model with a nonlinear spring and damper is also proposed and the parameters will be optimized with different damper and spring characteristics and optimization algorithms. The optimization algorithms used are interior-point and firefly algorithm. The objective of this paper is to compare different methods used to establish a simple model of a car crash an…
Renewable polyol obtained by microwave-assisted alcoholysis of epoxidized soybean oil: Preparation, thermal properties and relaxation process
2019
[EN] The soybean oil polyol (SOP) use as feedstock in the polyurethane industry has been recently emphasized due to its excellent resistance to hydrolysis, which is also applicable in coatings and thermal insulation. In this article, the SOP was obtained by a very fast microwave-assisted alcoholysis of epoxidized soybean oil (ESO). The preparation method, thermal properties, and relaxation process were evaluated. High yields as opening and consumption epoxy group and selectivity of 99.8 mol%, 985 mol%, and 71.2 mol% were obtained. Through titrations, nuclear magnetic resonance and gel permeation chromatography were identified parameters as 0.32 mg KOH.g(-1) acid number, 190 mg KOH.g(-1) hyd…

Avoiding accidents at the champagne reception: A study of joint lifting and balancing
2017
Using a lifting and balancing task, we contrasted two alternative views of planning joint actions: one postulating that joint action involves distinct predictions for self and other, the other postulating that joint action involves coordinated plans between the coactors and reuse of bimanual models. We compared compensatory movements required to keep a tray balanced when 2 participants lifted glasses from each other’s trays at the same time (simultaneous joint action) and when they took turns lifting (sequential joint action). Compared with sequential joint action, simultaneous joint action made it easier to keep the tray balanced. Thus, in keeping with the view that bimanual models are reu…
