Degradation mechanisms under hydro-thermo-mechanical loads of natural fibers-reinforced biocomposites : application to the development of lightweight…
2018
With the current environmental concerns, research turns to alternative solutions to synthetic fibres. Vegetal fibers appears as good candidates, with good mechanical properties. However, their low durability is a major issue, especially when the composites are exposed to hydro(hygro)thermal loadings.The purpore of this thesis is to analyse and understand the degradation mechanisms when hydro-thermo-mechanical loadings are applied, in order to implement a predictive modelisation of the composite durability.The manufacturing process wasstudied and optimised to produce reproducible and strong composites. Two materials were produced. Their only difference is their volumetric fiber contents (37.…
L'utilisation de la musique comme support de nouveaux apprentissages dans le vieillisement normal et la maladie d'Alzheimer
2012
This thesis research aims to test the potential of music as a mnemonic support for new learning in normal elderly and Alzheimer’s disease (AD) participants. Several studies have highlighted the beneficial effects of music on cognition in aging and dementia. At the same time, in young adults, the idea that music could serve as a mnemonic support is highly debated. Yet, very few studies addressed this question in aging or dementia. In the present work, we conduct two studies in a cohort of 8 mild Alzheimer’s disease and 7 matched control participants. The first study concerns verbal memory, and compares learning and different retention delays of lyrics (unknown texts) that are either spoken o…
Macular pigment change during eye ageing : analysis from population based study, Montrachet study
2018
Given the limits of the literature on the environmental nutritional impact in ocular aging witch is partially due to the lack of data in general population notably in French elderly, first, we were interested in the relationships of diet, plasma xanthophylls and macular pigment optical density as well as its spatial distribution and second of plasma fatty acids and dry eye disease signs in the 1153 Montrachet study participants.Firstly, we reported the high consumption of squash, the high plasma lutein and zeaxanthin levels and also the high plasma lutein level, the high macular pigment optical density level in nonsmokers subjects. In addition, the macular pigment values we provided in the …
The implicit motor learning use as a therapeutic tool in frail elderly people
2016
To write, take, walk, talk is a part of our daily. Our motor ability is used to change depending on our environment and our skill, acquired thanks to our experience, learnings, and according to our age. We strive to find optimal solutions, to be more performants, more efficient. But we must be able to discern to act well and act to better discern. This « perception-action » coupling is the basis of the organization of motor control. Human can discern through several sensory systems (Visual, auditory, proprioceptive) intrinsic informations, coming from his own body, and extrinsic informations, from his environment. All of these informations are in the service of the movement and actions of d…
Estimating COVID-19-induced Excess Mortality in Lombardy, Italy.
2022
We compare the expected all-cause mortality with the observed one for different age classes during the pandemic in Lombardy, which was the epicenter of the epidemic in Italy. The first case in Italy was found in Lombardy in early 2020, and the first wave was mainly centered in Lombardy. The other three waves, in Autumn 2020, March 2021 and Summer 2021 are also characterized by a high number of cases in absolute terms. A generalized linear mixed model is introduced to model weekly mortality from 2011 to 2019, taking into account seasonal patterns and year-specific trends. Based on the 2019 year-specific conditional best linear unbiased predictions, a significant excess of mortality is estima…
Is immunosenescence infectious?
2004
Abstract Herpes viruses are endemic. Once established, the virus is never eliminated but persists throughout life. The fraction of infected individuals gradually increases with age, such that the majority of elderly people are cytomegalovirus (CMV) + , Epstein–Barr virus (EBV) + and Varicella + . Clinically relevant reactivation of Varicella causes painful shingles; CMV reactivation can cause fatal pneumonia. Overt reactivation, even in the very elderly, occurs only in immunocompromised individuals; however, the necessity for maintaining immunity to these viruses is costly. We argue that this cost is not only reflected in the requirement for continuous immunosurveillance against these virus…
Le vieillissement des personnes en situation de handicap : un regard démographique sur la Bourgogne-Franche-Comté
2018
The aging of people with disabilities has become, in the last forty years, a significant issue in the medico-social sector and also in our society. The lengthening of life is a positive phenomenon, a result of the efforts to professionalize the accompaniment of people with disabilities. Aging is a process, certainly irreversible, but natural. If a few people are the rare witnesses, in the 1980s, the phenomenon grows with time and becomes a demographic phenomenon. For the demographer, the notion of aging applies to a population and not to individuals. The observation of this process makes it possible to predict the trend of the changing needs of a population in the health, social and medico-…
Résidents et personnel en établissement d'hébergement pour personnes agées dépendantes (EHPAD) : création ou recréation de liens spécifiques en milie…
2019
This thesis studies the specific relationship that develops between the staff, the residents and their family and friends in retirement homes for dependents elderly in a rural environment.The aim is to analyse the creation process by the actors to go from an acquaintanceship network to an interdependence network and how each adapts, reorganise, more or less, among facilities where the legislator codified strongly the relational framework.The arrival to a retirement home marks, in all cases, a strong biographical break. For a little of people, it means having to accept abandoning a significant part of their past life. It forces the residents to (re)build themselves a new identity, a new stat…
Mitä mieltä, professorit?
2006
25 vuoden ikään ehtinyt Aikuiskasvatus kysyi kaikilta aikuiskasvatuksen professoreiltamme heidän näkemyksiään neljässä asiassa. Kaikkiin ei tarvinnut vastata. Tällaista kysyttiin ja näin vastasivat Yrjö Engeström ja Reijo Miettinen Helsingin yliopistosta, Anneli Eteläpelto Jyväskylän yliopistosta, Jukka Tuomisto ja Juha Suoranta Tampereen yliopistosta, Risto Rinne Turun yliopistosta, Kari E. Nurmi Lapin yliopistosta sekä vt:nä virkaa hoitava Leena Ahteenmäki-Pelkonen Joensuun yliopistosta. Vastausjärjestys on arvottu.
Luonto ja eläimet Eija-Liisa Ahtilan teoksessa Tänään
2014
Sivuttukielmassa käsitellään taiteilija Eija-Liisa Ahtilan kolmikanavaista videoinstallaatiota Tänään (1996–1997). Erityisesti pohditaan teoksesta avautuvia käsityksiä luonnosta ja eläimistä. Taustaksi tutkimukselle esitellään videoinstallaatioiden kehitystä taidemuotona 1990-luvun lopulla sekä erityisesti Eija-Liisa Ahtilan tapoja käyttää monikuvainstaalaatiota taiteensa välineenä. Myös Ahtiloan tuotannossa olennaiset käsitteet aika, paikka ja subjekti tulevat myös kytketyiksi tutkimukseen.
