The effects of optimizing blood inflow in the pedicle on perforator flap survival: A pilot study in a rat model
2020
Background Perforator flaps have led to a revolution in reconstructive surgery by reducing donor site morbidity. However, many surgeons have witnessed partial flap necrosis. Experimental methods to increase inflow have relied on adding a separate pedicle to the flap. The aim of our study was to experimentally determine whether increasing blood flow in the perforator pedicle itself could benefit flap survival. Methods In 30 male Lewis rats, an extended posterior thigh perforator flap was elevated and the pedicle was dissected to its origin from the femoral vessels. The rats were assigned to three groups: control (group I), acute inflow (group II) and arterial preconditioning (group III) dep…
Génèse et évolution des compétences des élèves à la fin de l'école maternelle : éléments d'analyse à partir de données de panel et d'une expérimentat…
2012
We propose to study in this thesis, a key issue and relatively little discussed in the French research in educational sciences, it concerns the genesis of pupil learning and their evolution during the tuition. We mobilize a longitudinal data (Panel 1997) and the results of a musical experimentation in kindergarten to answer to these questions: How are structured the first acquisitions of pupils and how is it linked to the school context and socio-economic variables? How the cognitive abilities of students affect their academic performance? Are specific activities can improve academic skills through an increase in cognitive abilities? Implicative analysis conducted on panel data has revealed…
A music educational daily program to develop cognitive abilities among pre-school children: a way to prevent academic failure?
2011
The idea that "music makes you smarter" and promotes verbal skills (Ho et al., 2003; Forgeard and al. 2000), spatiotemporal capacities (Rauscher and Zupan 2000) or even the QI (Schellenberg 2006) has received attention from general public and researchers. In this study we examined the effects of music training on pre-school and school performance of kindergarten children, in particular the early writing skills. One main question is investigated: what are the benefits of a specific music program for the cognitive abilities development on preschooler children (age 5)? Is it a way to prevent academic failure? We test this hypothesis with a large sample of 487 French preschoolers split up into …
Does a musical program improve the development of cognitive abilities on kindergarten students: a French experience?
2011
The idea that "music makes you smarter" and promotes both cognitive skills as verbal skills (Ho et al., 2003; Forgeard and al. 2000), spatiotemporal capacities (Rauscher and Zupan 2000), school performances (Wetter et al. 2009) or even boost the IQ (Schellenberg, 2004, 2006) has received attention from researchers and general public. In this study we examined the effects of music practice on pre-school and school performance of kindergarten children, in particular concerning early writing skills. Here, one main question is investigated: what are the benefits of a specific music program in the curriculum for the cognitive abilities development on preschooler children (age 5)?
A framework for IoT service experiment platforms in smart-city environments
2016
Cities provide an excellent platform for gathering and detection of massive amount of data from cities and citizens. Emergence of new digital technologies inspires not only city governments but also city residents, researchers, companies and other stakeholders in discovering and creating new innovative solutions to solve urban challenges and improve peoples´ everyday life. Developing novel Internet of Things (IoT) solutions for cities and citizens requires facilities where IoT applications and services can be tested and experimented. The challenge for many smart-city test and experimentation platforms (TEPs), like living labs, has been the lack of sustainable value creation model. This has …
Carattere Universale. Innovazione senza Stile
2019
Il Bauhaus (1919-1933) ha segnato la storia. Questa scuola fu animata da alcuni degli artisti-progettisti più rilevanti del Novecento, da Gropius a Kandinskij, da Itten a Moholy-Nagy, non riconducibili a un approccio univoco. Eppure, l’idea del Bauhaus, che ha innervato il dibattito e la pratica del progetto in Europa e negli USA (e non solo) per decenni, si è risolta in una sorta di International Style che, nella tipografia, corrisponde al carattere Universal di Herbert Bayer (1925). Il presente articolo mira a evidenziare come il carattere universale, che raffigura per noi oggi lo ‘stile’ della Modernità, fu in principio innovazione allo stato puro: una configurazione volta all’effetto, a…
Enseñanza de Estadística en un contexto multidisciplinar: una experimentación en un instituto italiano
2019
III Congreso Internacional Virtual de Educación Estadística (CIVEEST), 21-24 febrero de 2019. [www.ugr.es/local/fqm126/civeest.html] This paper describes an experiment performed at a Vocational School in Palermo during the school year 2010-11. It was designed to teach Statistics at the Secondary level following a multidisciplinary approach. The didactic activity involved the mathematics, Italian, English language and science teachers. We adapted materials and methods from the M@t.abel E-learning program, which is planned for learning basic mathematics in a middle school, in order to use it for experimentation at a professional school. The assessment of the experimentation is based on teache…
INNOVAZIONE DEI MATERIALI NATURALI: TERRA E NANOTUBI DI ARGILLA PER UNA SFIDA SOSTENIBILE
2019
All’interno del dibattito culturale che vede la questione ambientale come prioritaria e con riferimento a studi e ricerche che negli ultimi anni hanno promosso materiali compositi a base di terra cruda, gli Autori, consapevoli della necessità che il rapporto fra Progetto e Materia debba assumere una nuova centralità supportato dalle specificità della Tecnologia dell’Architettura, illustrano le risultanze di una sperimentazione che ha l’obiettivo di migliorare le prestazioni della terra cruda con l’apporto delle nanotecnologie, sviluppando un ‘nuovo materiale’ con una ridotta embodied energy e una ridotta quantità di emissioni di CO2 in atmosfera.
