Epidemiology, Physiology and Clinical Approach to Sleepiness at the Wheel in OSA Patients: A Narrative Review
2022
Sleepiness at the wheel (SW) is recognized as an important factor contributing to road traffic accidents, since up to 30 percent of fatal accidents have been attributed to SW. Sleepiness-related motor vehicle accidents may occur both from falling asleep while driving and from behavior impairment attributable to sleepiness. SW can be caused by various sleep disorders but also by behavioral factors such as sleep deprivation, shift work and non-restorative sleep, as well as chronic disease or the treatment with drugs that negatively affect the level of vigilance. An association between obstructive sleep apnea (OSA) and motor vehicle accidents has been found, with an increasing risk in OSA pati…
Yksikammioisten sydänlasten motorinen kehitys 16 ja 52 viikon iässä, vertaileva tutkimus
2009
Tausta: Suomessa syntyy vuosittain noin 20 lasta, joilla on vaikea-asteisimpiin sydänvikoihin kuuluva yksikammioinen sydän, hypoplastinen vasemman kammion oireyhtymä (HLHS) tai muu yksikammioinen sydänvika (UVH). Aikaisemmin nämä lapset menehtyivät pian syntymän jälkeen. Suomessa on alettu hoitaa näitä lapsia vuodesta 1995 Norwoodin ym. 1980 kehittämän kolmivaiheisen leikkausmenetelmän avulla, jonka ansiosta suurin osa näistä lapsista jää henkiin. Näiden lasten kokonaiskehitys ja etenkin motorinen kehitys on osoittautunut olevan jäljessä verrattuna terveisiin lapsiin. Tutkimuksia, joissa yksikammioisten sydänlasten varhaista motorista kehitystä on tarkemmin kuvattu ja analysoitu ei ole löyt…
Durability of a 3D woven composite assisted by finite element multi-scale modelling
2012
International audience; The textile composite studied is a 3D woven composite. A unit cell is defined by using microscopic examinations of the microstructure. A multiscale approach assisted by the finite element method is performed in order to estimate the effective properties of the composite and then to access to local stress field. This approach allows the determination of the kind of load to which warp yarns are subjected. Moreover, detailed analysis of damaged model using different configurations of broken yarns are treated. The evolution of the stress concentration coefficient highlight the load transfers due to consecutive yarn breaks.
A Multidimensional Ethics Scale for Indian Managers' Moral Decision Making
2010
This paper analyses the role of traditional moral theories in managers’ moral decision making using the multidimensional ethics scale (MES) developed and refined by Reidenbach and Robin (1988, 1990). This study extends their work by examining the applicability of the scale to subjects from India, other than the country in which the scale was developed. The research question is: what kind of ethical dimensions do Indian managers reveal when they are making moral decisions. Factor analysis is done to investigate the role of five moral philosophies (justice, deontology, relativism, utilitarianism, and egoism) in their ethical decision-making. The results show that the scale holds for the diffe…
Analysing SET over time using multilevel multidimensional explanatory IRT models
2013
This contribution makes an attempt to analyze students' ratings of university teaching on a broad prospective, trying to adjust the final assessment from a wide range of factors which jointly may influence the process under evaluation: academic year peculiarities, course characteristics, students' characteristics and item dimensionality. From a methodological point of view, by setting complex Item Response models as special case of Generalized Linear or Mixed Models a large flexibility is introduced in the specification of ad hoc modelling approaches for the analysis of students' ratings.
Objects as artifacts: synchronic convergence in multilingual contexts
2011
In this paper, I propose a shift in analytic focus from language to artifacts – that is, to personally meaningful objects that surface in interaction and generate talk – as a means of accounting for the historical dimension of the relationship between form and meaning. Artifacts activate memories and feelings from other times and places, informing ways of speaking in the conversational here-and-now. By applying discourse analysis to a conversation recorded during fieldwork at a social center for Spanish senior citizens in Paris, I show how various timescales – that is, the microgenetic scale of unfolding talk, the “series of connected discourse events” over weeks, months or even years, and …
Predicting mechanical behaviour and damage kinetics of a 3D interlock composite materials by using a multiscale approach
2012
International audience; The present work aims to investigate the mechanical behaviour and the damage kinetics of a3D interlock woven fabric composite, especially used for natural gas tanks dedicated to thetransportation industry. On the one hand, we aim at predicting the macroscopic coefficients ofthe stiffness matrix by homogenization multiscale approach. For this, we identified a basicunit cell which represents well the composite microstructure. On the other hand, damagemechanisms are analyzed: optical microscopy examinations on damaged specimens revealedseveral types of defects. We used the same multi-scale approach to assess the impact of thesedefects on the decrease of stiffness.
Global representation and multiscale expansion for the Dirichlet problem in a domain with a small hole close to the boundary
2019
For each pair (Formula presented.) of positive parameters, we define a perforated domain (Formula presented.) by making a small hole of size (Formula presented.) in an open regular subset (Formula presented.) of (Formula presented.) ((Formula presented.)). The hole is situated at distance (Formula presented.) from the outer boundary (Formula presented.) of the domain. Thus, when (Formula presented.) both the size of the hole and its distance from (Formula presented.) tend to zero, but the size shrinks faster than the distance. Next, we consider a Dirichlet problem for the Laplace equation in the perforated domain (Formula presented.) and we denote its solution by (Formula presented.) Our ai…
