Full textThis thesis is part of the field of the characterization of wireless communication systems using antennas diversity. Indeed, such systems allow fighting against the signals fading, when the terminal is inside a strong multipath environment. The issue of such research is: to study the association of multiple antennas at transmitting and/or receiving sides to improve the link budget, and the capacity of wireless systems, (decrease of BER (Bit Error Rate), increase of throughput …). This thesis takes an interest to the electromagnetic aspect, and signal processing. In order to understand the involved phenomena, and to characterize the terminal performance, it should be placed in a controlled multipath propagation environment in time, and in space. This brings us to find measurement methodologies able to reproduce models of realistic propagation channels. As part of this thesis the method used is the reverberation chamber. In this thesis we are interested in the time aspect. Reverberation chamber (RC) is considered as a useful tool to emulate rich multipath environments. In this contribution, this device is employed to emulate multi clusters channel models (cluster is defined as a group of multipath), and evaluate performance of wireless communication systems. This evaluation is performed with real time and not-real time measurements. It remains to note that among the objectives set out in this PhD thesis is to obtain electromagnetic simulation model of the reverberation chamber based on circuit approach, in order to determine the channel transfer function versus losses quantities

Full textOne has to have the knowledge of the transepithelial absorption method for active molecules, as it is a necessity for rational formulation. Among various in vitro methods, the Ussing chamber technique stands out not only by its relative ease to implement, but mostly through the practical arrangements of the molecules through the digestive epithelium (active/passive transport, paracellular/transcellular, transport efflux, metabolic effects) and electrophysiological characteristics and viability of the tissue.Firstly, we will present the general principles of the technique, the electrical parameters used for the interpretation of physiological data. Eventually, we will suggest a methodology for evaluating the transmembrane passage of active molecules.The experimental part of the work is aimed to evaluate the contribution of this model approach when it comes to measuring the impact of the formulations of molecules (solutions or colloidal dispersions) on the flow of absorption.So initially we worked around with two molecule models, paracetamol and vitamin C, as the nature of physiological solutions implemented could have a significant effect on the electrophysiological function of the membrane, it could change its conductance, and therefore change its transepithelial permeability.Secondly, concerning the collaborative work, we used the Ussing model to characterize the absorption of molecules when they were previously associated with various colloidal systems. On the one hand, we have shown that the combination of resveratrol, a very hydrophobic molecule, has microemulsions which allow an increase by a factor from x6 to x11, the passage of transresveratrol compared to native resveratrol. Additionally, we also showed that the combination of heparin, a lower molecular weight, extremely hydrophilic and poorly absorbed, but when associated with squalene nanoparticles, makes it possible to significantly increase the absorption flow.As a conclusion, all our work shows through Ussing chamber model, that when one wants to detail the physico-chemical and biological mechanisms, the nanoparticles can indeed improve the digestive passage, for those molecules which are poorly absorbed naturally

Full textIn general, inhalation of particles is at the origin of inflammatory and oxidative reactions who are responsible of the degradation of biological cellular constituents, and could have a strong cardiovascular impact. The wood combustion is a major source of semivolatile organic compounds such as the methoxyphenols (MPs) including coniferyl aldehyde (CA), syringaldehyde (SR), or acetosyringone (AS). The MPs are however few studies into literature while toxicity of other compounds also from biomass combustion, as carbon monoxide, soot and polycyclic aromatic hydrocarbon are intensively studies.This work has shown by GC/MS that aging in simulated atmosphere (ozone + light rays) degraded CA in secondary products less cytotoxic, studies on fribroblastes culture but keep the atmospherical level of SR and AS which have a toxicity proved.A device of MPs particle production original by atomization, with a check system (height, composition, weight) and exposition flow continuous (Ø~50 nm, N~7E4 particles/cm3, m~5 µg/m3) adapted to little animals, was developed and validated, allowed the first study in vivo with these molecules. Between 1 and 3 month of exposition to rat Wistar, show modified antioxidant defences and cardiac modification (ischaemia/reperfusion) principally with AS, then CA and less SR. The adaptatives processes (remodeling) are demonstrated after 5 month of exposition.Furthermore, it is showed in vitro on lung adenocacinum cell lines (A549), CA induced a monolayer destructuration and apoptosis (caspase 3) but no effect proinflammatory (IL8, Cox-2 and iNOS).To conclude, this work contributes to study the impact of MPs in vitro and in vivo

Thesis, Université de Lorraine, 2017. http://www.theses.fr/2017LORR0123/document.
Full textThe uniqueness of Oldoinyo Lengai to emit natrocarbonatite lavas makes this volcano a natural laboratory to study the genesis of these magmas. New helium isotopic data permit to assert that the signature of the fumaroles has been constant since 1988 despite the radical morphological change of the summit crater after the last sub-Plinian eruption in 2007-2008. The alternation of the effusive and explosive eruptions does not cause major modifications in the hydrothermal system architecture, which is inferred to be deeply rooted. Cognate xenoliths that were emitted during the eruption in 2007-2008 represent a unique opportunity to document the igneous processes occurring within the active magma chamber. The comparison between the noble gas (helium) isotopic compositions of the active magma chamber and those of the other silicate volcanoes of the Arusha region indicates that both types of magmatism have similar sources, identified as being a typical sub-continental lithospheric mantle, which was previously metasomatized by asthenospheric fluids. Moreover, these isotopic signatures confirm that no crustal contamination has occurred during the magma ascent from the mantle to the surface. Detailed petrographic descriptions coupled to a thermo-barometric approach, and to the determination of volatile solubility models for a phonolite composition, allow us to identify the melt evolution at magma chamber conditions and the storage parameters. These results indicate that the magma injected in 2007 has a phonolitic composition and contains a high amount of volatiles (3.2 wt.% H2O and 1.4 wt.% CO2) as well as a temperature around 1060° C. This magma subsequently evolved in the crustal magma chamber located at 11.5 ± 3.5 km depth until reaching a nephelinite composition and a temperature of 880°C. During the differentiation in the magma chamber, the silicate magma is enriched in calcium, sodium, magnesium and iron, whereas the content of silicate, potassium and aluminum decreases. Our results support previous studies related to this eruption, and are similar to the historical products emitted during the whole volcano history, permitting the suggestion that no major modification in the plumbing system has occurred during the Oldoinyo Lengai evolution. The trace elements (REE, LILE and HFSE) measured in the minerals and melt inclusions reveal a concentration reaching 100 to 1000 times the primitive mantle composition. A preliminary experimental study based on the recharge melt composition (phonolite) and identified magma chamber conditions (P, T) permits to reproduce the immiscibility between silicate and carbonatite liquids, key processes at the origin of the Oldoinyo Lengai carbonatites. The continuation of this experimental study will lead to a better comprehension of the carbonatite genesis, thus improving our understanding of the processes that are responsible for the enrichment in trace elements
