Nanoscale mechanical characterization of polymers by AFM nanoindentations: Critical approach to the elastic characterization

2006

AFM nanoindentations show a dependence of penetration, i.e., the relative motion between the sample and the tip (indenter), on material elastic properties when using the same load. This elationship becomes visible by using of samples being homogeneous down to the scale of nanoindentation. They were prepared from materials covering a broad range of mechanical behavior: from rubbery networks to glassy and semicrystalline polymers. The elastic modulus can be obtained applying Sneddon’s elastic contact mechanics approach. To do this, some calibrations and instrumental features have to be measured accurately. All the polymers tested show that the contact between the tip and the sample is dominat…

Deposition of very thin uniform indium sulfide layers over metallic nano-rods by the Spray-Ion Layer Gas Reaction method

2013

Abstract Very thin and uniform layers of indium sulfide were deposited on nickel nano-rods using the sequential and cyclical Spray-ILGAR® (Ion Layer Gas Reaction) technique. Substrates were fabricated by electrodeposition of Ni within the pores of polycarbonate membranes and subsequent chemical dissolution of the template. With respect to the depositions on flat substrates, experimental conditions were modified and optimized for the present geometry. Our results show that nano-rods up to a length of 10 μm were covered uniformly along their full length and with an almost constant film growth rate, thus allowing a good control of the coating thickness; the effect of the deposition temperature…

Pathways between Social Capital and Oral Health from Childhood to Adolescence

2022

Author's accepted manuscript This study aimed to evaluate the theoretical pathways by which social capital can influence dental caries and oral health–related quality of life (OHRQoL) of children over time. This 10-y prospective cohort started in 2010 with a sample of 639 preschoolers aged 1 to 5 y from the southern Brazil. Community and individual social capital were assessed at baseline through the presence of formal institutions in the neighborhood and social networks, respectively. In the 10-y follow-up, the individual social capital was evaluated by social trust and social networks. Dental caries was measured by the International Caries Detection and Assessment System (ICDAS), and the …

Donner le choix du repas à l'hôpital : effets sur le gaspillage alimentaire et les représentations du patient

2018

International audience; L’hospitalisation survient comme étant une rupture dans la vie d’une personne. Projetée dans un environnement parfois inconnu, avec un rythme imposé par une organisation établie, les habitudes et rituels peuvent être bousculés lors de l’arrivée dans l’institution de santé. Le repas, qui représente une valeur forte dans notre société et un repère avec la vie précédant l’hospitalisation, est totalement redéfini. Il perd ses dimensions identitaire et commensale au profit des dimensions médicale et nutritionnelle. Les prises alimentaires peuvent alors diminuer, entrainer une diminution des apports énergétiques pouvant aller jusqu’à l’apparition d’une dénutrition. Le but …

Les sépultures de Truchtersheim "Holderacker" (Bas-Rhin) et les pratiques funéraires du Bronze A1 dans le sud de la plaine du Rhin supérieur

2023

Die Freilegung 2019 eines kleinen frühbronzezeitlichen (2030-1900 v. Chr.) Bestattungsensemblesin Truchtersheim „Holderacker“, etwa 12 km nordwestlich von Straßburg, hat uns bewegt uns mit der gesamten für das Elsassverfügbaren Dokumentation der frühbronzezeitlichen Bestattungssitten zu befassen. Dieser bisher kaum dokumentiertechronologische Horizont wurde kürzlich durch eine Reihe von Funden bereichert, die vorwiegend zwischen 2017 und 2019bei präventivarchäologischen Operationen im Vorfeld der Bauarbeiten der Westumgehung von Straßburg entdeckt wurden.Das bescheidene regionale Corpus mit 20 Gräbern erlaubt nur begrenzte Beobachtungen, es weist jedoch doch mehrere für dieFrühbronzezeit ch…

DOCS ICI, COURTS LÀ : UNE ALTERNATIVE DE DIFFUSION POUR LES FILMS REGIONAUX EN BOURGOGNE-FRANCHE-COMTÉ ?

2021

sous la direction de Christel Taillibert, Jean-Paul Aubert et de Cyril Laverger; International audience; Docs ici, courts là est un dispositif qui valorise les courts métrages et les documentaires produits et/ou réalisés en Bourgogne-Franche-Comté. À travers cette étude de cas, l’auteure rend compte de ses observations et de ses questionnements sur la portée alternative de ce dispositif qui se décline à plusieurs niveaux. Il est complémentaire ou alternatif aux modes de diffusion de films standards (salles de cinéma, festivals, télévision), lorsque les œuvres sont projetées dans des lieux « atypiques ». Mais sa portée alternative se révèle sur d’autres de ses aspects et actions qu’il met en…

Multiscale variation in drought controlled historical forest fire activity in the boreal forests of eastern Fennoscandia

2017

Forest fires are a key disturbance in boreal forests, and characteristics of fire regimes are among the most important factors explaining the variation in forest structure and species composition. The occurrence of fire is connected with climate, but earlier, mostly local-scale studies in the northern European boreal forests have provided little insight into fire-climate relationship before the modern fire suppression period. Here, we compiled annually resolved fire history, temperature, and precipitation reconstructions from eastern Fennoscandia from the mid-16th century to the end of the 19th century, a period of strong human influence on fires. We used synchrony of fires over the network…
