Abstract This study proposes a novel method for predicting the microcrack propagation in composites based on coupling the local and non-local micromechanics. The special feature of this method is that it can take full advantages of both the continuum micromechanics as a local model and peridynamic micromechanics as a non-local model to achieve composite fracture simulation with a higher level of accuracy and efficiency. Based on the energy equivalence, we first establish the equivalent continuum micromechanics model with equivalent stiffness operators through peridynamic micromechanics model. These two models are then coupled into a closed equation system, More >

Abstract Objectif : Le décès brutal d’un jeune parent malade du cancer affecte profondément le conjoint et les enfants. La famille doit alors s’adapter à l’absence du défunt et se réorganiser pour élever au mieux les enfants. Les très jeunes enfants sont particulièrement vulnérables car ils n’ont généralement pas la possibilité d’exprimer leur souffrance. Pour leur donner la parole, nous avons conçu un dispositif innovant, La Petite Fille aux Allumettes, qui s’inscrit dans une démarche de démocratie en santé. Méthode : Nous avons évalué les effets de leur participation au groupe pour une population de huit enfants et leur… More >

Abstract An innovative microcrystalline cellulose (MCC) natural fibre powder-reinforced PLA biocomposite was investigated using the hand lay-up technique. The polymer matrix composite (PMC) samples were prepared by varying the weight percentages (wt.%) of both PLA matrix and MCC reinforcement: pure PLA/100:0, 90:10, 80:20, 70:30, 60:40 and 50:50 wt.%, respectively. From the results obtained, MCC powder, with its impressive aspect ratio, proved to be an ideal reinforcement for the PLA, exhibiting exceptional mechanical properties. It was evident that the 80:20 wt.% biocomposite sample exhibited the maximum improvement in the tensile, flexural, notched impact, compressive strength and hardness… More >

Abstract Background: Exercise procrastination is prevalent among college students, causing decline in physical fitness. It is imperative to investigate the mechanism affecting college students’ physical activity behaviors. This study was aimed at investigating the effect of procrastination on college students’ physical exercise behavior, and the chain mediation effects of exercise commitment and action control (AC), to provide a theoretical basis for interventions targeting physical exercise behavior among college students. Methods: A questionnaire survey was conducted using convenience sampling. The General Procrastination Scale, Exercise Commitment Scale, Action Control Scale, and Physical Activity Rating Scale-3 questionnaires were used.… More >

Abstract Handwritten character recognition is considered challenging compared with machine-printed characters due to the different human writing styles. Arabic is morphologically rich, and its characters have a high similarity. The Arabic language includes 28 characters. Each character has up to four shapes according to its location in the word (at the beginning, middle, end, and isolated). This paper proposed 12 CNN architectures for recognizing handwritten Arabic characters. The proposed architectures were derived from the popular CNN architectures, such as VGG, ResNet, and Inception, to make them applicable to recognizing character-size images. The experimental results on three More >

Abstract Objective: The importance of good sleep for energy recovery and overall physical and mental health cannot be overstated. However, the increasing competitiveness of society, diversifying lifestyles, and the rapid spread of the internet and electronic devices have significantly impacted people’s sleep patterns, particularly through bedtime procrastination. Therefore, this study aims to investigate the relationship and underlying mechanisms between sleep determination, anxiety, and bedtime procrastination among the Chinese population. Method: The study utilized data from a national survey—the China Residents’ Sleep Condition Survey (November 2021, with 6,037 participants). By constructing mediation and moderation models, it analyzed the… More >

Abstract Microcrystalline cellulose (MCC) is one of the cellulose derivatives produced as a result of the depolymerization of a part of cellulose to achieve high crystallinity. When implemented in other polymers, high crystallinity correlates with greater strength and stiffnes, but it can reduce the water-holding capacity. The acid concentration and hydrolysis time will affect the acquisition of crystallinity and water absorption capacity, both of which have significance as properties of hydrogel filler. The study aimed to evaluate the properties and select the MCC generated from varying the proportion of hydrochloric acid (HCl) and the appropriate hydrolysis… More > Graphic Abstract

Abstract Cet article vise à partager une expérience innovante d’organisation et de financement de la recherche ayant impliqué les premiers concernés : les patients. Le groupe de travail « ECLAIR » du Cancéropôle Lyon Auvergne-Rhône-Alpes (CLARA) a été créé en fin d’année 2020 dans le but de contribuer à l’élaboration d’un appel à projets portant sur l’expérience patient en cancérologie, ouvert en janvier 2021. Constitué au départ de 8 membres dont 7 patients, coordonné par un chef de projets du CLARA, le groupe de travail ECLAIR a activement contribué à l’écriture du cahier des charges de… More >

Abstract Cet article présente l’histoire et les enjeux de la diplomation des patients en la posant comme un dispositif de soutien de l’engagement des patients et des usagers du système de santé. Un ensemble de lois relatives aux droits des malades et à la qualité du système de santé permettent l’intégration des patients dans le système de santé mais elles se heurtent à la non-préparation des institutions à ce nouveau champ de pratiques. La diplomation des patients nécessite des transformations dans les modes d’accueil et de financement des universités et aussi dans les méthodes pédagogiques qui More >
