Study of a sample of faint Be stars in the exofield of CoRoT
2013
International audience; Context. Be stars are probably the most rapid rotators among stars in the main sequence (MS) and, as such, are excellent candidates to study the incidence of the rotation on the characteristics of their non-radial pulsations, as well as on their internal structure. Pulsations are also thought to be possible mechanisms that help the mass ejection needed to build up the circumstellar disks of Be stars.Aims. The purpose of this paper is to identify a number of faint Be stars observed with the CoRoT satellite and to determine their fundamental parameters, which will enable us to study their pulsation properties as a function of the location in the HR diagram and to searc…

Deimatism: a neglected component of antipredator defence
2017
Deimatic or ‘startle’ displays cause a receiver to recoil reflexively in response to a sudden change in sensory input. Deimatism is sometimes implicitly treated as a form of aposematism (unprofitability associated with a signal). However, the fundamental difference is, in order to provide protection, deimatism does not require a predator to have any learned or innate aversion. Instead, deimatism can confer a survival advantage by exploiting existing neural mechanisms in a way that releases a reflexive response in the predator. We discuss the differences among deimatism, aposematism, and forms of mimicry, and their ecological and evolutionary implications. We highlight outstanding questions …
Bioethics and neuroethics
2019
Neuroethics officially appeared at the start of the 21st century due to the progress made by the neurosciences, as an applied ethics related to bioethics, but also as an independent discipline in its own right. As an applied ethics, it tackles issues bordering on bioethics. As independent neuroethics, it deals with established philosophical problems from a neuroscientific standpoint in the broader sense. It involves two central questions: the design of a framework in which to select, interpret and integrate data from neuroscience on morality and outlining the appropriate method or methods for this new branch of knowledge. In both cases, most neuroethicists curiously claim to take a naturali…
Terrorism in the Website
2020
Without any doubt, terrorism causes higher levels of anxiety and very well enhances our fears as never before. The post 9/11 context witnesses the multiplication of xenophobic expressions, such as Islamophobia or tourist-phobia, only to name a few. These expressions result from a culture of intolerance, which not only was enrooted in the ideological core of western capitalism but was accelerated just after 9/11. Some voices emphasize the needs of employing technology to make this world a safer place. This chapter goes in a contradictory direction. The authors focus on the ethical limitations of technologies when they are subordinated to the ideals of zero-risk society. Echoing Sunstein and …
Nursing Taxonomies in Spain: Research Themes Presented at the AENTDE Conferences Over a 16-Year Period
2016
Objective To identify the types of studies of nursing taxonomies and priority research themes presented at AENTDE conferences between 1996 and 2012. Method Four hundred oral communications and posters and 27 lectures presented at the AENTDE meetings were reviewed by means of a descriptive analysis of the types of studies conducted and a content analysis of priority research themes. Results The most commonly presented studies were descriptions of the implementation of nursing taxonomies, which accounted for 27.4% of the total over the 16-year period. However, their prevalence fell from 31.8% in 1996 to 9.1% in 2012. Basic research studies accounted for 17.4% of studies overall but were the m…
Antibacterial properties and reduction of MRSA biofilm with a dressing combining polyabsorbent fibres and a silver matrix
2016
Objective: This study was designed to evaluate the antibacterial activity of a wound dressing which combines polyacrylate fibres and a silver lipido-colloid matrix (UrgoClean Ag, silver polyabsorbent dressing), against biofilm of methicillin-resistant Staphylococcus aureus (MRSA). Method: Samples of silver polyabsorbent dressing and the neutral form of this dressing (UrgoClean) were applied to biofilms of MRSA formed on a collagen I-coated surface, cultured for 24 hours. Different exposure times were tested (1, 2, 4 and 7 days) without dressing change. The biofilm reduction was quantified by using culture methods and by confocal laser scanning microscopy experiments. Results: The applicatio…
Low-energy Tests of Fundamental Physics
2018
This article presents a personal perspective on why it is interesting and important to test all kinds of fundamental laws and search for as-yet-undiscovered particles and interactions using laboratory-based non-accelerator techniques. Such room-scale experiments are already spearheading discovery, and can be expected to become even more important as accelerators reach seemingly inevitable limits.
Minors and Transexuality
2020
[ES] En el ámbito de la transexualidad los poderes públicos han ejercido desde un principio una política claramente restrictiva que ha requerido de años para poder abrirse a las nuevas necesidades y a la sociedad actual. Así, la normativa en la materia era totalmente excluyente de los menores de edad, considerándolos carentes de aptitud alguna para poder decidir sobre su identidad sexual y todo lo que ello conllevaba, quizá porque como afirman algunos autores “la finalidad básica de esa prohibición es la de garantizar que la decisión de la rectificación registral sea una decisión firme y coherente, evitando así cambios arbitrarios o no fundados en el sexo” (Vázquez-Pastor, 2010).Esta idea p…
Contenidos fundamentales de la Dermatología en el grado de medicina en España. Recomendaciones del grupo de profesores de la Academia Española de Der…
2016
Antecedentes: Los problemas dermatologicos constituyen uno de los motivos de consulta masfrecuentes en atencion primaria. En los ultimos a˜nos, como consecuencia de la adaptacion alespacio europeo de educacion superior, en muchos planes de estudios se ha reducido el tiempodestinado al aprendizaje de la dermatologia.Material y metodos:Para consensuar los contenidos basicos del programa de dermatologia enel pregrado, se remitio electronicamente una encuesta a los 57 miembros de grupo de profeso-res de la Academia Espa˜nola de Dermatologia y Venereologia para establecer cuales deberianser los objetivos de aprendizaje de la asignatura en Espa˜na. Se incluyeron 131 objetivos previa-mente selecci…
