Nuclear data activities at the n_TOF facility at CERN
2016
International audience; Nuclear data in general, and neutron-induced reaction cross sections in particular, are important for a wide variety of research fields. They play a key role in the safety and criticality assessment of nuclear technology, not only for existing power reactors but also for radiation dosimetry, medical applications, the transmutation of nuclear waste, accelerator-driven systems, fuel cycle investigations and future reactor systems as in Generation IV. Applications of nuclear data are also related to research fields as the study of nuclear level densities and stellar nucleosynthesis. Simulations and calculations of nuclear technology applications largely rely on evaluate…
Efeito dos aspectos trabalhistas na comunicação, inteligência emocional e empatia em enfermagem
2019
Objetivo: determinar o impacto do tipo de contrato e do tempo de serviço prestado da equipe de enfermagem nas suas atitudes em relação à comunicação, inteligência emocional e empatia. Métodos: os instrumentos que avaliam as atitudes em relação à comunicação, empatia e inteligência emocional. A amostra do estudo consistiu de 450 enfermeiras de 7 hospitais. Para avaliar o efeito das variáveis estudadas, foram realizados ANOVA unilateral, correlações de Pearson e modelos de regressão linear hierárquica múltipla, de acordo com o tipo de contrato. Resultados: há diferenças estatisticamente significativas entre as variáveis estudadas de acordo com o tipo de contrato. Mais especificamente, a equip…
Plataformas digitales y contratación electrónica: conflictos derivados y métodos de resolución
2022
El presente artículo parte de la noción de economía colaborativa en el marco del comercio electrónico; un concepto difuso que se entrelaza con otros como el de economía de plataformas y que al mismo tiempo cuenta con ciertas variantes como la de consumo colaborativo. En este entorno confuso, analizamos los sujetos implicados que participan en las formas de contratar electrónicamente dentro de dicha economía de plataformas, planteando los tipos de relaciones contractuales que existen entre ellos para posteriormente centrarnos en las formas de solucionar los conflictos que deriven de dicha situación. En este punto, prestamos especial atención a las posibilidades de aplicar distintos mecanismo…
Una intervención didáctica sobre Cambio Climático y Sostenibilidad dirigida a alumnado y profesorado de Secundaria, en el marco de los ODS
2022
En esta comunicación se presenta parte de una investigación-acción diseñada e implementada desde el año 2019 y que todavía está en progreso. La intervención tiene como objetivo general fomentar la incorporación de los principios y valores de la Sostenibilidad en la práctica docente desde una perspectiva holística con especial atención al proceso de Cambio Climático acelerado, en Educación Secundaria, trabajando de forma colaborativa con el profesorado y atendiendo a las necesidades e intereses específicos del alumnado. Tras un recorrido de casi tres cursos académicos se presenta una sinopsis de lo realizado, analizando con mayor detalle la intervención realizada en un centro educativo. This…
Attraction of egg-killing parasitoids toward induced plant volatiles in a multi-herbivore context
2015
In response to insect herbivory, plants emit volatile organic compounds which may act as indirect plant defenses by attracting natural enemies of the attacking herbivore. In nature, plants are often attacked by multiple herbivores, but the majority of studies which have investigated indirect plant defenses to date have focused on the recruitment of different parasitoid species in a single-herbivore context. Here, we report our investigation on the attraction of egg parasitoids of lepidopteran hosts (Trichogramma brassicae and T. evanescens) toward plant volatiles induced by different insect herbivores in olfactometer bioassays. We used a system consisting of a native crucifer, Brassica nigr…
INTEGRATING ONTOLOGY AND COGNITIVE LINGUISTICS FOR NATURAL LANGUAGE PRODUCTION AND UNDERSTANDING
2012
Ontologies have been designed to capture the semantic knowledge of a domain in a machine understandable form. Current standards for managing ontologies like OWL are lacking in linguistic grounding, and are not able to achieve a clear link with natural language. Bridging this gap, unskilled users could be able to infer the information described in the ontology and it would be possible either producing or parsing utterances about the represented domain automatically. Moreover, as in the case of enterprises, it could be very useful to extract information from external documental corpora that are related to the same domain. Many attempts have been made with the aim to create a natural language …
Object Recognition and Modeling Using SIFT Features
2013
In this paper we present a technique for object recognition and modelling based on local image features matching. Given a complete set of views of an object the goal of our technique is the recognition of the same object in an image of a cluttered environment containing the object and an estimate of its pose. The method is based on visual modeling of objects from a multi-view representation of the object to recognize. The first step consists of creating object model, selecting a subset of the available views using SIFT descriptors to evaluate image similarity and relevance. The selected views are then assumed as the model of the object and we show that they can effectively be used to visual…
Periodontitis and preterm delivery. A review of the literature
2005
The aim of this paper was to review the relationship between periodontitis and preterm delivery (PTD). Original papers on this subject, published in English until the first quarter of 2004, were located in the MEDLINE/PubMed database. Additional papers were obtained by searching reference lists of previously published review papers. Case control studies pointed to an association between periodontitis and increased rates of PTD of low birth-weight (LBW) infants. Longitudinal studies showed that the incidence or progression of periodontitis during pregnancy may be an independent risk factor for PTD and LBW. Microbiological, immunological and animal model studies suggested that periodontal pat…
La mémoire d’une autre réconciliation : le récit des anciens collaborationnistes au lendemain de la Seconde Guerre mondiale
2007
International audience; Fritz Taubert s’intéresse dans cet article à une autre mémoire vive des relations franco- allemandes : celle portée après la guerre par d’anciens collaborateurs. Il montre comment ces hommes ont tenté de justifier a posteriori leur action pendant l’Occupation en opérant une équivalence sémantique entre la Collaboration, le rapprochement, et la réconciliation franco- allemande. Fritz Taubert souligne que ce discours social n’est pas resté cantonné aux cercles de nostalgiques de la Collaboration. Sous la guerre froide, l’anticommunisme lui a offert une caisse de résonance de telle sorte qu’il a participé à la construction du sens en marge des récits officiels sur la co…
