The hermaphroditic gastropod Lymnaea stagnalis is proposed as a candidate species for the development of OECD guidelines for testing of the reprotoxicity of chemicals, including endocrine active substances (EASs). Up to now, only a few putative EASs have been tested for their reproductive toxicity in this species. In this study, we investigate the effects of four EASs with different affinities to the vertebrate estrogen and androgen receptors (chlordecone as an estrogen; cyproterone acetate, fenitrothion and vinclozolin as anti-androgens) on the reproduction of L. stagnalis in a 21-day semi-static test. Testosterone and 17α-ethinylestradiol (EE2) were used as the reference compounds. The tested EASs had no significant effect on growth and survival at the tested concentration ranges (ng to μg/L). Classical reproduction endpoints (i.e., oviposition and fecundity) were not responsive to the tested chemicals, except for chlordecone and 17α-ethinylestradiol, which hampered reproduction from 19.6 μg/L and 17.6 μg/L, respectively. The frequency of polyembryonic eggs, used as an additional endpoint, demonstrated the effects of all compounds except EE2. The molecular pathways, which are involved in such reproduction impairments, remain unknown. Our results suggest that egg quality is a more sensitive endpoint as compared to other reproductive endpoints commonly assessed in mollusk toxicity tests. [less ▲]

Cette contribution interroge les pratiques de pédagogie multimodale instrumentée des Massive Open Online Courses au travers d’une étude énonciative. Partant du principe que la communication multimodale instrumentée utilise différentes médiations sémiotiques (vidéo, peinture, dessin à la main, graphique, schéma, sonorité, musique etc.) nous nous proposons d’observer et d’analyser ces types de modalités communicationnelles telles que mises en place par les mooc. Ce, dans l’objectif de saisir la variété des pratiques multimodales auxquelles recourent les Massive Open Online Courses. Nous tentons également de souligner ce qui définit la spécificité de ces pratiques et la manière dont l’étude sémiotique des stratégies énonciatives peut-elle contribuer aux questionnements actuels en sciences de la communication. Nous répondons à ces questions à travers l’analyse de deux mooc issus de deux plateformes différentes : The Future of Storytelling de la plateforme Iversity et Scientific Humanities de la plateforme France Université Numérique.

Cette étude porte sur l’utilisation du dispositif SDC (Studio Digital Collaboratif) dans un projet collaboratif pédagogique de conception architecturale. Dans une perspective sémiotique, nous étudions le fonctionnement de la communication médiatisée dans les ateliers de formation par projet. Dans ces ateliers, les encadrants suivent l’avancement du projet de la conception architecturale des étudiants à travers les séances hebdomadaires de correction des documents. Ainsi, nous nous focalisons sur le rôle de l’opérateur — ici une des équipes collaboratrices — en adoptant le point de vue de la sémiotique des pratiques (J. Fontanille, Pratiques sémiotiques, Paris, PUF, 2008). Une perturbation dans l’activité collaborative des étudiants pendant l’atelier est au centre de notre propos et nous permettra de problématiser la question de l’appropriation, de la désappropriation et de la réappropriation de la pratique distante et simultanée. Cette perturbation nous permettra également de valoriser le rôle de l’opérateur dans la gestion d’une activité collaborative outillée en cours d’accomplissement. [less ▲]

Clam farming in coastal provinces of Vietnam has notably developed since the last decade. It generated high income, improve socio-economic development for many local communities. However, many clam raising farms are facing difficulties of farm management, disease control, markets and systems of quality control. This research aims to study about the real situation of cost monitoring in the clam raising farms in the Northern area of Vietnam and suggest some recommendation for apply a suitable model for cost monitoring to promote the value added for farmers. The paper based on the semi-structure, standard questionnaires and PRA method to collect data from 89 clam raising farms in two coastal provinces (Nam Dinh and Thai Binh) in the Northern area of Vietnam in 2014. The findings show that clam raising provides farmers a chance of getting high income parallel with high risk. There were 32.15% surveyed farms got profit, 32.14% of them met the breakeven and 35.71% was lost. The study finds out four key factors affecting farms’ economic performance and efficiency. The first is capacity of farm cost control as the cost for clam raising was very high at 8,142 to 9,190 USD per ha. The second is the farmers’ experience, skill, technique and ability of risk control. The third is low, unstable market price and unsuitable market channel with the dominant of the traders. Final factors is the area and location of clam raising. Despite of these difficulties, 55.14% surveyed farms still want to expand their production, 25% of them will continue, and only 17.86% will stop or change to other activities. In order to promote the value added for clam raising farmers, cost control should be paid more attention, improvement of the farmers’ capacity is necessary, and market should be regarded. [less ▲]

One current challenge related to computational fracture mechanics is the modeling of ductile fracture and in particular the damage to crack transition. On the one hand, continuum damage models, especially in their non-local formulation which avoids the loss of solution uniqueness, can capture the material degradation process up to the localization of the damage, but are unable to represent a discontinuity in the structure. On the other hand cohesive zone methods can represent the process zone at the crack tip governing the crack propagation, but cannot account for the diffuse material damaging process. In this paper we propose to combine, in a small deformations setting, a non-local elastic damage model with a cohesive zone model. This combination is formulated within a discontinuous Galerkin nite element discretization. Indeed this DG weak formulation can easily be developed in a non-local implicit form and naturally embeds interface elements that can be used to integrate the traction separation law of the cohesive zone model. The method remains thus consistent and computationally e cient as compared to other cohesive element approaches. The effects of the damage to crack transition and of the mesh discretization are respectively studied on the compact tension specimen and on the double-notched specimen, demonstrating the efficiency and accuracy of the method.
