Melhoramento ético das práticas em saúde: Comitês de Bioética em Espanha e Brasil
2017
O compartilhamento solidário de experiências entre Brasil e Espanha reposiciona a importância de novos espaços democráticos de participação cidadã e debate ético-político, suscitando questões como: a participação em Comitês Bioéticos pode ir em direção às necessiades-interesses sociais presentes na singularidade da relação profissional-paciente e equipe de saúde? No Brasil, a participação dos profissionais em fóruns construídos para ampliação do controle social e debate da ética, avança como permanente desafio. A ampliação da deliberação em coletivos de debate e equipes de saúde, precisa assumir novo sentido público social na construção da relação profissional-usuário-sistema de saúde-socie…
Human DNA Telomeres in Presence of Oxidative Lesions: The Crucial Role of Electrostatic Interactions on the Stability of Guanine Quadruplexes
2019
By using all atom molecular dynamics simulations, we studied the behavior of human DNA telomere sequences in guanine quadruplex (G4) conformation and in the presence of oxidative lesions, namely abasic sites. In particular, we evidenced that while removing one guanine base induces a significant alteration and destabilization of the involved leaflet, human telomere oligomers tend, in most cases, to maintain at least a partial quadruplex structure, eventually by replacing the empty site with undamaged guanines of different leaflets. This study shows that (i) the disruption of the quadruplex leaflets induces the release of at least one of the potassium cations embedded in the quadruplex channe…
Sykepleiestudentenes kliniske praksis – om klinisk læringsmiljø og studenttilfredshet

Nurse practice – clinical learning environment and student satisfaction
 The purpose of this study was to investigate nursing students’ satisfaction with the clinical learning environment during clinical practice. A questionnaire was distributed to nursing students at a university (N=250) in Norway. Student satisfaction, task orientation, pedagogical atmosphere, supervisory relationship, and the premises of nursing on the ward were measured. Of the 250 students invited, 163 (66 %) completed the survey. Nursing students were largely satisfied with their clinical placement experiences, but they were more satisfied with hospital placements than home care placements. Supervision more than …
« Je n’abandonnerai pas tant que je n’aurai pas retrouvé Potsdamer Platz »
2012
Homer, vieillard à lunettes interprété par Curt Bois, apparaît pour la première fois dans Les Ailes du désir (Der Himmel über Berlin, Wim Wenders, 1987) au cours de la fameuse séquence filmée à la Staatsbibliothek zu Berlin. Il monte difficilement les escaliers tout en invoquant la muse de sa voix intérieure : « Raconte, Muse, le conteur, l’enfantin, l’antique. » Il est écouté par son ange, Cassiel (Otto Sander). Puis, la caméra flottante de Wim Wenders continue son exploration du Berlin cont...
Le recours aux catégories dans la gestion du choix au cours d’un repas au restaurant
2012
Ce travail, ancre dans le champ de l’Analyse Conversationnelle (Sacks, 1992), s’interesse a une question centrale a laquelle les clients sont perpetuellement confrontes lors de la prise d’un repas au restaurant : le choix. Plus precisement, nous nous interessons a son caractere situe et a son deploiement en interaction en nous basant sur un corpus audiovisuel collecte en situation « naturelle » de production, lors de repas au restaurant, afin d’etudier la parole-en-interaction telle qu’elle est localement produite et organisee par les participants (Heath, Hindmarsch & Luff, 2010). Apres avoir expose le lien entre identite et alimentation et la notion de categorisation telle qu’elle a ete de…
On the Prevalence of Addicted or Problematic Gaming in Finland
2019
Highlights • A dataset from Finland in 2015 (systematic random sampling N = 4511) suggests an (unweighted) prevalence rate of certain “addicted gaming” (videogame play) to be 0.6% among local gamers and 0.03% among the whole population. • The implied prevalence of certain “problematic gaming” (videogame play) climbs to 1.4% among local gamers and 0.6% among the whole population. • Of those “addicted” individuals to whom videogame play was a problem “almost always,” eight reported their hours of play during a week (72, 30, 10, 7, 4, 1, 1, 1), which indicate that “addicted gaming,” if understood as excessive play, might not be optimal for describing such problems.
A NEW TOOL FOR THE STUDY OF RESONANCE IN CHEMICAL EDUCATION
2014
The objective of this study is to present a computer-based project, for which our program POLAR and our version of PAPID were written for the study of the subject of resonance in chemistry. Both algorithms allow a better didactic strategy and methodological adaptation for the study of molecular properties in chemical education. Teachers will find the options of POLAR and PAPID useful for demonstrations. It is still to be explored the methodological application of these computational programs enriching the present teaching techniques. Implementing new algorithms in learning situations is technically simple, but checking their usefulness in teaching practice is extraordinarily complex and req…
Bathymetry time series using high spatial resolution satellite images
2020
The use of the new generation of remote sensors, such as echo sounders and Global Navigation Satellite System (GNSS) receivers with differential correction installed in a drone, allows the acquisition of high-precision data in areas of shallow water, as in the case of the channel of the Encañizadas in the Mar Menor lagoon. This high precision information is the first step to develop the methodology to monitor the bathymetry of the Mar Menor channels. The use of high spatial resolution satellite images is the solution for monitoring many hydrological changes and it is the basis of the three-dimensional (3D) numerical models used to study transport over time, environmental variability, and wa…
Task Planner for Robotic Disassembly of Electric Vehicle Battery Pack
2021
The rapidly growing deployment of Electric Vehicles (EV) put strong demands on the development of Lithium-Ion Batteries (LIBs) but also into its dismantling process, a necessary step for circular economy. The aim of this study is therefore to develop an autonomous task planner for the dismantling of EV Lithium-Ion Battery pack to a module level through the design and implementation of a computer vision system. This research contributes to moving closer towards fully automated EV battery robotic dismantling, an inevitable step for a sustainable world transition to an electric economy. For the proposed task planner the main functions consist in identifying LIB components and their locations, …
