Consistency Between the Subjective Perception of Feeling Indisposed, the Decision to Drive and Driving Performance
2016
Drivers' health and fitness are essential issues in order to predict traffic crashes, taking into account that these characteristics are essential to perform this task correctly and safety. The purpose of this research was to analyze the frequency in which drivers who feel physically or emotionally unable to drive decide to perform this task, or not, under states of indisposition, as well as the perception of the effect that this indisposition had on driving. This cross-sectional study used a total sample of n=1200 (666 [56%] men and 534 [44%] women) Spanish drivers, who answered a questionnaire designed to collect data about their psychosocial characteristics, driving habits and perception…
SAFETY CONSIDERATIONS ON TEENAGE PEDESTRIAN-BUS IMPACT
2019
This work studies the impact conditions between the adolescent pedestrian and the bus focusing on head and chest injury. The injury to the head is analyzed using both the Head Injury Criterion (HIC) 36 and the HIC15 parameters as established by the most advanced legislation and comparing the risk probability Abbreviated Injury Scale (AIS3+) and AIS4+. The parameter HIC15 gives a higher probability of risk with lower values, and therefore it can be considered more conservative. Moreover, the study of chest injury is performed with two different biomechanical parameters: the Thoracic Trauma Index (TTI) and the TTI(d); the last neglects the pedestrian mass. The results indicate that the param…

Bicycle Rider Behavior and Crash Involvement in Australia.
2021
This research investigated how behaviours and attitudes of bicycle riders influence crash frequency and severity. The study recruited 1102 Australian bicycle riders for an online survey. The survey comprised questions on demographics, frequency of riding and the number and severity of traffic crashes during the last five years. The survey included the Cycling Behaviour Questionnaire and the Cyclist Risk Perception and Regulation Scale. Overall, there were low levels of errors and violations reported by participants indicating that these behaviours were on average never or rarely exhibited while riding a bicycle. Conversely, participants reported high levels of engagement in positive behavio…
Lièvre et lapin à Regourdou (Montignac-sur-Vézère, Dordogne, France) : études paléontologique et taphonomique de deux accumulations osseuses d’origin…
2015
Since the end of the nineteenth century, a great deal of work studyingsubsistence patterns of prehistoric societies in Western Europe has been done. During the Middle Paleolithic, humanswere interested in small game, particularly the Leporidae, taxa that were abundant in their territories. However,distinguishing the exact nature of their origin in an archaeological site is not an easy task, given that numerous agentscould be responsible for their accumulation (i.e., natural mortality, acquisition by humans and/or other terrestrialcarnivores, or even nocturnal or diurnal raptors). In this contribution, we put forth a new taphonomic and paleontologicalstudy of the leporids of Regourdou, a Mou…
Actividad antioxidante y biodisponibilidad mineral de zumos de frutas adicionados de minerales y/o leche
2010
En los últimos años, la industria alimentaria ha incrementado su interés en el desarrollo de alimentos funcionales, siendo el enriquecimiento de bebidas a base de zumo de frutas con vitaminas y minerales uno de los métodos empleados. Esta estrategia persigue mejorar el estado nutricional de la población, o de grupos específicos de población y/o corregir posibles deficiencias en la ingesta diaria de vitaminas o minerales, debidas a cambios en los hábitos alimentarios. No obstante, se precisa un mayor conocimiento sobre las interacciones que puedan producirse entre los compuestos bioactivos de las bebidas a base de zumo de frutas y los minerales adicionados, o viceversa. Para ello, se estudia…
La Muestra Continua de Vidas Laborales (MCVL) como fuente generadora de datos para el estudio del sistema de pensiones
2015
Esta tesis tiene como elemento fundamental de análisis la denominada Muestra Continua de Vidas Laborales (MCVL), como fuente generadora de datos para el estudio del sistema de público de pensiones de España. La MCVL es un conjunto de microdatos individuales anonimizados extraídos de los registros de la Seguridad Social de España. La MCVL se obtiene a partir de un Muestreo Aleatorio Simple (MAS) sobre la población de referencia (conjunto de personas relacionadas durante todo el año con la Seguridad Social, bien como afiliadas o bien como perceptoras de prestaciones, pero con ciertos matices en dicha relación). Los objetivos principales de esta tesis son: - Contribuir a aumentar el conocimien…
Safety Evaluation of α-Lipoic Acid Supplementation: A Systematic Review and Meta-Analysis of Randomized Placebo-Controlled Clinical Studies
2020
Alpha-lipoic acid (ALA) is a natural short-chain fatty acid that has attracted great attention in recent years as an antioxidant molecule. However, some concerns have been recently raised regarding its safety profile. To address the issue, we aimed to assess ALA safety profile through a systematic review of the literature and a meta-analysis of the available randomized placebo-controlled clinical studies. The literature search included EMBASE, PubMed Medline, SCOPUS, Google Scholar, and ISI Web of Science by Clarivate databases up to 15th August 2020. Data were pooled from 71 clinical studies, comprising 155 treatment arms, which included 4749 subjects with 2558 subjects treated with ALA an…
