The purpose of this thesis is to study magnetic reconnection in collisionless and relativistic plasmas. Such plasmas can be encountered in various astrophysical objects (microquasars, AGNs, GRBs...), where reconnection could explain high-energy particle and photon produ...

The thesis focuses on the relation to academic writing in French as a foreign and second language (FFL/SL). Our objective is to propose an approach of academic literacy in FFL/SL, to describe and to understand the relation to writing in FFL/SL of the group investigated,...

This PhD thesis focuses on issues related to the financing, the determinants and the barriers of renewable energy (RE) in the energy transition. To address these issues, we focus in Chapter 1 at identifying the determinants of solar PV capacities' deployment, and at inv...

Synthesis gas can be obtained by biomass gasification. It is composed of CO and H2 and can be used for the production of electricity, organic coumpounds and biofuels. The use of sewage sludges allows exploiting this kind of waste as biomass resources. However, sewage sl...

The first part of this thesis is dedicated to the modification of polyelectrolytes to form polyelectrolyte films with controlled and stretch responsive cell and protein adsorption properties. Poly(acrylic acid) (PAA) was modified with side phosphorylcholine groups (PC) ...

A classic understanding of neurotransmitter clearance at glutamatergic synapses is that, in order to ensure sufficient glutamate uptake on a fast timescale, it is necessary to have high numbers of glutamate transporters in the vicinity of release sites to compensate for...

Nowadays piezoelectric transformers are not only used to supply or protect electrical devices, but also to generate plasma discharges directly on their surface. The remarkable properties of these piezoelectric generators make them an interesting alternative to conventio...

Virus discovery has long depended on the observation of outbreaks, and the research to understand their pathogenicity depended on their culture. The advances of sequencing technology and molecular biology tech-niques allowed researchers to discover the ubiquity and the ...

Single-source HTTP Adaptive Streaming solutions (HAS) have become the de-facto solutions to deliver video over the Internet mostly due to their capabilities to increase end-user’s Quality of Experience (QoE) as well as their ease of deployment due to the usage of the HT...

Developed. The method is based on the two-dimensional micropolar continuum theory and makes use of the kinematic approach of limit analysis in conjunction with a rigorous homogenization technique. The method is introduced in a general way, with regard to the genericclas...
