Influence du vieillissement hygrothermique sur la tenue à l'impact de stratifiés quasi-isotropes/quasi homogènes

2011

International audience; La présente étude a pour objectif de déterminer l'influence du vieillissement hygrothermique sur la tolérance à l'impact de stratifiés possédant des propriétés particulières d'isotropie. Trois stratifications de 24 plis carbone/époxy ont été étudiées. Deux d'entre elles conduisent à des propriétés d'isotropie en membrane et en flexion, la troisième est isotrope en membrane et anisotrope en flexion. Les stratifiés obtenus après cuisson suivant le cycle préconisé par le fabricant ont été découpés pour obtenir des éprouvettes carrées destinées au vieillissement et à l'impact. Le vieillissement a été réalisé grâce à une enceinte climatique à une température de 70 °C sous…

Israeli Crowdfunding: A Reflection of Its Entrepreneurial Culture

2020

AbstractCrowdfunding has its roots deep in the Israeli entrepreneurship ecosystem. Its characterizing elements of—collective individualism combined with flat social hierarchies, low degree of separation, mandatory army service that enforces innovative thinking and improvisation, Chutzpah, and finally high tolerance for failure, all provide fertile ground for entrepreneurship and facilitate innovative approaches to entrepreneurship funding such as crowdfunding. In light of this, the growth of crowdfunding in Israel is not surprising. While the equity crowdfunding leads the field, rewards and donations platforms are more known and popular, indeed the brand name of the senior rewards and donat…

Chirurgie cardiaque sous circulation extra-corporelle et ses biomarqueurs : rôle du Growth / Différentiation Factor 15 (GDF 15) : études cliniques

2016

Ischemic cardiac diseases are the most frequent and deleterious pathologies leading to important cardiovascular-related mortality worldwide. One of the alternative therapies consists to treat these patients using cardiac surgery. Cardiopulmonary bypass was developed to greatly improve this surgical procedure. However, some adverse effects can occur during cardiac surgery associated with cardiopulmonary bypass due to the inflammatory response. This phenomenon is the result of various mechanisms including oxidative stress and inflammatory cytokines which lead to multi-organ failure and then to myocardial and renal injuries occurring during the peri- and post-operative periods.The first part o…

B-type natriuretic peptide trend predicts clinical significance of worsening renal function in acute heart failure

2019

Aims In acute heart failure (AHF), relationships between changes in B-type natriuretic peptide (BNP) and worsening renal function (WRF) and its prognostic implications have not been fully determined. We investigated the relationship between WRF and a decrease in BNP with in-hospital and 1-year mortality in AHF. Methods and results The Acute Kidney Injury NGAL Evaluation of Symptomatic heart faIlure Study (AKINESIS) was a prospective, international, multicentre study of AHF patients. Severe WRF (sWRF) was a sustained increase of >= 44.2 mu mol/L (0.5 mg/dL) or >= 50% in creatinine, non-severe WRF (nsWRF) was a non-sustained increase of >= 26.5 mu mol/L (0.3 mg/dL) or >= 50% in cr…

International audience; Le propos de cet article est de caractériser, sur un plan théorique, la nature de l'expérience vécue par le consommateur lors de la consultation d'Internet, de façon à trouver le meilleur design d'un site commercial. Il compare l'expérience de consultation vécue selon que l'objectif initial poursuivi par l'utilisateur est la distraction ou la recherche d'information. Il examine les sources de gratifications et de frustrations contribuant à la valorisation de cette expérience.

Individual and shared digital repertoires : older adults managing digital services

2023

The rise of public and other non-recreational digital services is based on the idea of catering to the daily needs of the citizens cost-efficiently and with ease. Previous research has approached the use of digital services mainly from the perspective of an individual, while the significance of shared practices of use has attracted only a little attention. In this article, we (1) examine the incentives and limitations associated with the use of non-recreational digital services, which either encourage or discourage older adults to use them. Based on the first question, we then ask (2) how older adults in this study manage those non-recreational digital services they have chosen to use. Our …

Ethnic differences in utilization of online health information sources : A test of the social inequality hypotheses

2023

The goal of the current study was to understand ethnic differences in use of online health information sources. Social stratification and social diversification hypotheses were used as study’s theoretical framework. The data were obtained from the 2017 Israel Social Survey (N = 2166). Multinomial and logistic regression techniques were used for the multivariate analysis. The results suggest that Israeli Arab respondents were less likely than Israeli-born Jewish respondents to seek health information using the Health Funds’ call centers or websites, other websites, and to utilize any number of the online health information sources. The findings provide a strong support for the social strati…

Social and satisfied? : Social uses of mobile phone and subjective wellbeing in later life

2022

The current study examined the associations between socio-demographic background and engagement in social uses of mobile phone, and between the engagement in these uses and life satisfaction and health satisfaction in later life through the lens of digital divide and uses and gratifications theories. The data, collected from the retired Internet users (62 and older) residing in seven countries (N = 5713), were analyzed using logistic and linear regression models. The results show that education and age predicted the engagement in social uses in the most consistent way. A number of social uses positively related to both life and health satisfaction. Of the particular uses, e-mailing and inst…
