Le principal site de production d’eau potable via des eaux souterraines d’Eau du Morbihan est situé à Beignon, dans le Nord-Est du Morbihan [A. Le Gal et al., 2015]. Les recherches d’eau réalisées ont permis de mettre en service en 2011 trois forages (FE3, FE4 et FE7), pour un débit total de 125 m3/h. Ces forages sont situés à proximité d’un cours ...
The use of space through satellites is more and more important for nations, companies, and individuals. However, since the first satellite was sent up in 1957, mankind has been polluting space with debris (i.e., artificial objects with no function), especially in low orbits (between 100 and 2000 km). The current situation is such that: 1/ space age...

The integrated life cycle assessment (LCA), life cycle cost assessment (LCC) and laboratory-based experimental assessment were applied to provide insight for early stage decision-making on the valorization of the dredged sediments. The objective was to find a viable and sustainable solution for the valorization of the dredged sediment in concrete, ...
In the field of Deep Learning, the long short-term memory (LSTM) networks lie in the category of recurrent neural network (RNN) architectures. The distinctive capability of the LSTM is learning non linear long term dependency structures. This makes the LSTM a good candidate for prediction tasks in non linear time dependent systems such as predictio...
Plastic food packaging represents 40 % of the plastic production worldwide and belongs to the 10 most commonly found items in aquatic environments. They are characterized by high additives contents with >4000 formulations available on the market. Thus they can release their constitutive chemicals (i.e. additives) into the surrounding environment, c...

Crop losses from pests threaten global food security and safety. In the last six decades, pest control using chemical pesticides has resulted in important yield gains per unit area, worldwide. However, the long-term sustainability of chemical pest control has been increasingly thrown into doubt due to the negative impact on human health, biodiversi...

Vermiculite and micaceous minerals are relevant Cs+ sorbents in soils and sediments. To understand the bioavailability of Cs+ in soils resulting from multi-cation exchanges, sorption of Cs+ onto clay minerals was performed in batch experiments with solutions containing Ca2+, Mg2+, and K+. A sequence between a vermiculite and various micaceous struc...
Lors de crues morphogènes, des volumes importants de bois peuvent être transportés par les flots et engendrer des accumulations (embâcles) au niveau de verrous hydrauliques (ponts, barrages, sections étroites). Ces embâcles peuvent entraîner un risque lorsqu’ils ont lieu au droit de zones à enjeux. Pour réduire ce risque, les modes de gestion les p...
Pedagogies in higher education, stimulated by various theoretical and philosophical schools of thought, have gradually changed the landscape, integrating, over the last 20 years, Virtual exchange (VE) on the one hand and Challenge-based learning (CBL) on the other. The present study focuses on the “Virtual Environmental Challenge” (VEC) which was l...
