Atmospheric dry deposition processes of particles on urban and suburban surfaces: Modelling and validation works
2019
Abstract Dry deposition process is one of the important pathways for the removal of particles from atmosphere. It is the result of a combination of different environmental and physical factors as atmospheric conditions, particle properties, characteristics of the canopy. For this latter factor, urban canopy represents unevenly combinations of different types of surface elements that increases the complexity of deposition process phenomena. Therefore, particle dry deposition on urban surfaces is not easy to configure and, although empirical or semi-empirical models in literature have been developed to address this aspect, there is not standardized and commonly accepted criteria, especially f…
Motorcyclists Safety System to avoid Rear End Collisions based on Acoustic Signatures
2017
International audience; In many Asian countries, motorcyclists have a higher fatality rate as compared to other vehicles. Among many other factors, rear end collisions are also contributing for these fatalities. Collision detection systems can be useful to minimize these accidents. However, the designing of efficient and cost effective collision detection system for motorcyclist is still a major challenge. In this paper, an acoustic information based, cost effective and efficient collision detection system is proposed for motorcycle applications. The proposed technique uses the Short time Fourier Transform (STFT) to extract the features from the audio signal and Principal component analysis…
Queratoconjuntivitis epidémicas en el trabajo. Reflexiones en torno a su manejo y catalogación
2019
Introducción: las conjuntivitis epidémicas presentan alto riesgo de contagio. Pueden tener etiología laboral. Objetivos: conocer datos epidemiológicos y cuantificar costes económicos; aportar información sobre manejo y catalogación. Material / Métodos: estudio descriptivo-retrospectivo de una serie de casos (contingencias profesionales) por conjuntivitis epidémica (CIE-9) durante 2014-2015 en FREMAP, que generaron procesos de incapacidad temporal. Resultados: sobre el total de patologías oftalmológicas laborales con baja, representaron el 1,6%. Mujeres 75%, sector servicios y 39 años de media. Bilateral 73% de los casos. El 46% recibió asistencia previa. Tratamiento médico 86,48% (colirios …
Science and law in the time of cholera: the mystery of the biscuits in Torroja (1865)
2018
By focussing on a case of collective poisoning in 1865, four features of forensic cultures are analysed: technologies for detection, authorized voices, regulations in action and the predominant social anxieties. Local newspapers and archival documents kept in the medical academies of Barcelona and Madrid are analysed. The analysis shows the tensions between various types of proof employed in legal medicine and the ambiguities between epidemic diseases and poisoning accidents. In the first section, I review the fears caused by the cholera epidemic in 1865, which was the first explanation of the accident. The changes of popular perception are also discussed by analysing contemporary newspaper…
Sleep apnea and its role in transportation safety
2017
Obstructive sleep apnea (OSA) is a main cause of excessive daytime sleepiness and increases the risk for driving accidents, which can be normalized by treatment with continuous positive airway pressure ventilation. Since it is estimated that OSA is not diagnosed in about 80% of cases, recognition of patients at risk for driving accidents is a problem from both medical and societal points of view. Strategies to screen and identify subjects at high risk for driving accidents are under study in order to improve safety on the road, especially for commercial drivers, who show a high prevalence of OSA.
REVIEW OF RETROSPECTIVE DOSIMETRY TECHNIQUES FOR EXTERNAL IONISING RADIATION EXPOSURES
2011
The current focus on networking and mutual assistance in the management of radiation accidents or incidents has demonstrated the importance of a joined-up approach in physical and biological dosimetry. To this end, the European Radiation Dosimetry Working Group 10 on 'Retrospective Dosimetry' has been set up by individuals from a wide range of disciplines across Europe. Here, established and emerging dosimetry methods are reviewed, which can be used immediately and retrospectively following external ionising radiation exposure. Endpoints and assays include dicentrics, translocations, premature chromosome condensation, micronuclei, somatic mutations, gene expression, electron paramagnetic re…
FACTORES HUMANOS ASOCIADOS A LOS ACCIDENTES MORTALES DE MOTOCICLETAS SCOOTER EN ESPAÑA
2017
Resumen Los accidentes de motocicleta son uno de los problemas de seguridad vial más importantes a nivel mundial. Hay una escasez de estudios específicos sobre las características de la accidentalidad de las motocicletas de tipo scooter, motivada por la falta de una definición precisa de este tipo de motocicleta y de la identificación de los distintos tipos de vehículos de dos ruedas en los registros de accidentes. El objetivo de este trabajo es determinar las características de los 293 conductores de motocicletas scooter fallecidos en España durante el periodo 2006-2011. Se realizaron análisis descriptivos y de asociación en función de la naturaleza de las variables. Los resultados de los …
Epidemiology, Physiology and Clinical Approach to Sleepiness at the Wheel in OSA Patients: A Narrative Review
2022
Sleepiness at the wheel (SW) is recognized as an important factor contributing to road traffic accidents, since up to 30 percent of fatal accidents have been attributed to SW. Sleepiness-related motor vehicle accidents may occur both from falling asleep while driving and from behavior impairment attributable to sleepiness. SW can be caused by various sleep disorders but also by behavioral factors such as sleep deprivation, shift work and non-restorative sleep, as well as chronic disease or the treatment with drugs that negatively affect the level of vigilance. An association between obstructive sleep apnea (OSA) and motor vehicle accidents has been found, with an increasing risk in OSA pati…
Dental treatment of patients with coagulation factor alterations: An update
2007
Hemostasia is a defense mechanism that protects vascular integrity, avoids blood loss, and maintains blood fluidity throughout the circulatory system. The biochemical processes leading to blood clot formation are complex, and alterations can appear at any point within the chain of events. While a range of alterations can affect the coagulation factors, some are more common than others in the general population, including congenital (hemophilia A and B, Von Willebrand’s disease) and acquired disorders (anticoagulant drugs). Such diseases require special consideration in the context of dental treatment, and therefore must be known to dental professionals. Interconsultation with the hematologi…
