On the mechanisms involved in the tensile strength of a dissimilar Ti6Al4V/316L laser welded assembly
2021
International audience; The aim of the present work is to analyze the thermomechanical behavior of dissimilar laser seams by means of FE modeling. The case of a Ti6Al4V/316L assembly with vanadium insert was considered. Effective mechanical properties of the main materials and cords were first estimated from NHT measurements. Modeling of the double pass laser welding process was performed first by considering shrinking of the two weld seams during manufacturing, to get the residual stress state in the welded assembly. Modeling of the tensile test was performed in a second step to study the assembly behavior during loading. In these modeling results, the mesh was the cross-section of the mic…
El uso político de Twitter en la campaña de las Elecciones Locales de 2015 en la ciudad de València
2020
La investigación analiza el uso político de Twitter en la campaña de las Elecciones Locales de 2015 en la ciudad de Valencia. El trabajo realiza una comparación de la presencia y de la actividad en dicha red de microblogging de las cinco formaciones políticas que obtuvieron representación en la corporación municipal (el Partido Popular, Compromís, Ciudadanos, PSPV-PSOE y València en Comú) y sus respectivos candidatos (Rita Barberá, Joan Ribó, Fernando Giner, Joan Calabuig y Jordi Peris). Lo hace mediante una metodología de análisis cuantitativo ya consolidada y que resulta especialmente conveniente para documentar la progresiva implantación de las aportaciones potenciales de la comunicación…
Microstructure impact on high temperature corrosion behavior of AISI 316L stainless steel additively manufactured by Selective Laser Melting (AM-SLM)
2019
International audience; Additive Manufacturing by Selective Laser Melting (AM-SLM) is a near-net shape method producing dense and geometrically complex materials from micrometric powders. This process involves complete melting and very high cooling rates who induce a refinement of microstructure, improving the mechanical properties of the material [1,2]. However, the impact of these new microstructures on real functioning properties, like for instance the high temperature durability, needs to be studied. In this purpose, AISI 316L is considered in this work. Samples elaborated by AM-SLM and by conventional metallurgy were oxidized under laboratory air at 900°C for periods up to 3000h. The r…
Additive manufacturing, new elaboration technique of metallic materials : impact of the microstructure on high temperature durability of AISI 316L st…
2021
Additive Manufacturing (AM) processes are able to elaborate, in a single step, metallic parts with very complex geometry, as close as possible to their final dimensions, based on 3D CAD model. Despite a very large number of studies on AM parameters, very few studies report on the high temperature behavior of the metallic materials produced by these processes. This thesis work evaluates the impact of the Selective Laser Melting (SLM) process on the high temperature durability of the austenitic stainless steel AISI 316L, commercial grade widely used in the industry. For this purpose, the reactivity of SLM samples was studied in different conditions (atmosphere, temperature, isothermal or cycl…
Organisational and individual resources as antecedents of older nursing professionals’ organisational commitment : Investigating the mediating effect…
2021
Aim and objectives To investigate how organisational and individual resources are linked to older (50+) nursing professionals’ organisational commitment, and to examine the possible mediating role of the active use of selection, optimisation and compensation (SOC) strategies. Background Many healthcare organisations need to find ways to retain their older nursing professionals due to nursing shortage. Design To test a set of hypotheses, cross-sectional survey data (n = 396) were used. Data were analysed using correlation analysis and partial least-squares structural equation modelling. STROBE Statement for cross-sectional studies has been followed in this study. Results The results exhibite…
Structure of self-rated health among the oldest old: Analyses in the total population and those living with dementia
2020
No previous study has explored the structure of self-rated health (SRH), a measure holding strong predictive value for future health events, in the oldest old or in individuals with dementia. The aim was to construct a structural equation model of SRH for oldest old in general and for oldest old with dementia, and to explore direct and indirect associations between health-related factors and SRH. Cross-sectional data from the Vitality 90+, a population-based study in the city of Tampere, Finland, was used. Data were gathered by a mailed questionnaire in 2014. Altogether 1299 nonagenarians, of which 408 had self-reported dementia or cognitive decline, were included. Structural equation model…
Un análisis de la educación familiar desde la teoría pedagógica: propuesta de bases fundamentales para un modelo integrado.
2004
Son diversas las disciplinas científicas que tienen como objeto de estudio la familia y, en particular, lo relativo al fenómeno educativo que acontece en su seno (Pedagogía, Psicología, Sociología, etc.); sin embargo, cuando se toma todo ese conjunto de aportaciones que nos ofrecen y se trata de ponerlas en común, parece no haber un cuerpo estructurado e integrado de tales conocimientos. Así, nos preguntamos: ¿existe algún modelo que explique, a la vez que norme, todo el conjunto de hechos, actuaciones y procesos que ocurren en la educación familiar?Este problema se traduce en tres objetivos: 1) revisar el conocimiento más relevante sobre educación familiar aportado por las diferentes disci…
Mental health promotion competencies in the health sector in Finland : a qualitative study of the views of professionals
2019
Aims: In this study, we aimed to investigate what competencies are needed for mental health promotion in health sector practice in Finland. Methods: A qualitative study was carried out to seek the views of mental health professionals regarding mental health promotion-related competencies. The data were collected via two focus groups and a questionnaire survey of professionals working in the health sector in Finland. The focus groups consisted of a total of 13 professionals. Further, 20 questionnaires were received from the questionnaire survey. The data were analysed using the qualitative data analysis software ATLAS.ti Scientific Software Development GmbH, Berlin. A content analysis was c…
