Full textTogether with geological and geometallurgical modeling, geotechnical modeling is one of the essential components for the planning and development of open pit and underground mining projects. A particular characteristic of many geotechnical variables is to be direction-dependent, i.e., the measurement of a core sample not only depends on the in-situ position of this sample but also on its in-situ orientation. To account for this characteristic, it is proposed to regionalize such variables in a five-dimensional space corresponding to the product on the three-dimensional geographical space and the two-dimensional sphere, so that each measurement is indexed by its easting, northing, elevation, azimuth, and dip. Instead of making predictions and simulations conditioned to a particular direction, this new paradigm allows geotechnical variables to be interpolated at any place in the geographic space, for any direction. The spatial correlation structure can be inferred and modeled by using separable covariances or combinations of separable covariances, under an assumption of stationarity in the geographical space and isotropy on the sphere. Also, conditional simulation can be performed by turning bands, based on products of stationary random fields in the geographic space and isotropic random fields on the sphere. The proposed methodology is illustrated with the modeling of the linear discontinuity frequency (P10), the rock quality designation (RQD), and Slope Mass Rating (SMR) in three mineral deposits

Full textThe flavor of cocoa and coffee are formed principally during roasting. The evolution of certain methylpyrazines has been studied using coupled steam distillation-microdistillation and determined by gas chromatography unsing nitrogen-phosphorus detector. The determination of methylpyrazines in cocoa beans (Ivory Coast) has shown the presence of the mono-, 2,3 di-, 2,5 di-, 2,6 di-, tri-, tri- et tetramethylpyrazine in non-roasted cocoa. During roasting, the methylpyrazines increase regularly but weakly, only the tetramethylpyrazine the most important compound reaches a maximum peak on concentration. For the coffee, the most important compound is the monomethylpyrazine. During roasting, all methylpyrazines reache a maximum peak of concentration. The composition in pyrazines for both products, particularly the value of certain report between different methylpyrazine, might provide information on flavor quality of cocoa and coffee

Full textProtein-energy malnutrition (PEM) is insufficiently investigated in pediatric wards. Since 2010, we initiated annual national then international multicentric surveys, which evaluated PEM frequency around 10%. PEM diagnosis is clinical and its severity depends on the impact on protein metabolism. It currently lacks a simple and reliable biological marker of PEM. The measurement of the hair bulk 15N natural isotopic abundance (NIA) is assessed as an index of the protein metabolism. This innovative measurement is a non-invasive method, suitable for Pediatrics.We observed a bulk hair 15N NIA systematically higher in the newborn from its mother, while amino acids come from the same source, suggesting a different protein metabolism. In diabetic nephropathy, bulk hair 15N NIA was correlated to glomerular function indices, and thus to the impact of chronic kidney disease on protein metabolism. In mice, protein restriction during gestation and/or lactation resulted in a modification of bulk hair 15N NIA at 16 months, suggesting a nutritional imprinting in adulthood. Our data in humans and animals suggest that an isotopic fractionation is linked to protein metabolism. Thus bulk 15N NIA may be a potential useful biomarker in clinical practice. Further researches in animals and cells are needed to explore the biochemical mechanisms of isotope fractionation

Full textThis thesis deals with the study of one physico-chemical property of molten fluorides media, fluoroacidity (pF which is equivalent to the pH for aprotic solvent), and its impact on the process. The fluoroacidity () of molten fluorides is presently unknown and the purpose of this work is to build a relative scale of fluoroacidity. This study was conducted in the first part using two approaches: - a kinetic study of stability of B(III) and Si(IV) ions, where the reaction leading to gaseous species (BF3(g) and SiF4(g)) is affected by the fluoroacidity. By comparing the rate constants of gas release, the different media were sorted and a relative scale of fluoroacidity was proposed. - the influence of fluoroacidity on the transport in solution, determined by measuring the diffusion coefficient and by calculating the adimensional Schmidt number (Sc=v/D) was investigated. Relationships between bridged fluorines, viscosity and fluoroacidity was evidenced, and the proposed fluoroacidity scale validated. Then, a stable reference electrode in molten fluorides was developed. Electromotive forces measurements of concentration cells were performed and the fluoroacidity impact on the potential of a redox couple was demonstrated. Thanks to this reference electrode, free F- activities ratios in different solvents were determined

Full textUse of body segment parameters close to reality is of the utmost importance in order to obtain reliable kinetics during human motion analysis. Human body is modeled as a various number of solids in the majority of human movement studies. This research aims at developing and testing two methods for the estimation of these solid masses, also known as segment masses. Both methods are based on the static equilibrium principle for several solids. The first method’s goal is to provide with limb masses using total limb centre of mass and centre of pressure, projection on the horizontal plane of the total subject’s body centre of gravity, displacements. Ratio between these displacement being the same as the ratio of limb and total body masses, the knowledge of the latter allows for the calculation of the former. The second method aims at estimation all segment masses simultaneously by resolving series of static equilibrium equations, making the same assumption that centre of pressure is total body centre of mass projection and using segment centre of mass estimations. Interest of the new methods used in this research is due to the use of individual segment centre of mass estimations using a geometrical model together with material routinely utilized in human motion analysis in order to obtain estimates of body segment masses. Limb mass estimations method performs better predicting a posteriori center of mass displacement when compared to other methods. Some of the potential causes of the second method’s failure have been investigated through the study of centre of pressure location uncertainty

Full textThe work presented in this manuscript is dealing with the synthesis of new three-dimensional molecular architectures and their evaluation as synthetic ion channels capable of promoting ion transmembrane transport. The first part aims at developing a straightforward approach to the synthesis of novel architectures based on a naphthothiophene platform, aromatic or partially hydrogenated, as well as the development of a strategy the convert 9-arylnaphthothiophene architectures into helical platforms. The properties of these molecules were studied in the solid state and were completed by theoretical calculations to highlight global topologies adopted. Theoretical calculations allowed us to understanding some reactivities observed. A second part is dedicated firstly to the functionalisation of these molecular architectures into amphiphilic molecules and secondly to study their abilities to insert themselves into a model bilayer lipid membrane by forming channels. Besides, in order to gain a better understanding of the interactions in play in the process, mass spectrometry analysis combined to theoretical calculations were set up

Full textLe mémoire présente le temps de réaction simple (TRS) chez les adolescents. Ce projet de recherche s’insère à l’intérieur d’un plus vaste projet de recherche qui visait à décrire l’état de certain déterminant des habiletés motrices, des fonctions exécutives et des paramètres psychologiques chez des adolescents. Peu d’études ont décrit le TRS chez les adolescents sains. Le but de cette recherche était de décrire l’état du TRS chez les adolescents, en fonction de l’âge, du sommeil et du percentile de l’indice de masse corporelle. L’échantillonnage comprenait 226 participants âgés entre 12 à 18 ans. Le test du TRS a été mesuré à partir d’un essai réalisé à l’ordinateur. Aucune différence significative n’a été observée entre les garçons et les filles pour le TRS. En comparant les TRS des participants (adolescents et adolescentes combinés) de deuxième secondaire au TRS des participants de 4e et 5e secondaire par une analyse de variance multivarié suivi par des tests post-hoc de type Tukey-Kramer ceci a permis d’observer des différences significatives (p<0,05). La même observation a été réalisée avec le nombre de rejets obtenus lors du test du TRS entre la 1e et la 5e secondaire. Nos résultats sont en concordance avec les résultats d’autres recherches. Le phénomène de diminution du TRS, au cours de l’adolescence, peut s’expliquer par la maturation du système nerveux (SN). L’analyse des données sur le sommeil, selon une classification en trois groupes (moins de 7h, 7h à 9h et plus de 9h) a permis de déterminer que la majorité des participants rapportent dormir le temps recommandé, soit entre 7 et 9 heures. Aucune corrélation n’a été obtenue entre le TRS et le nombre d’heure de sommeil en effectuant une corrélation linéaire de Pearson. La littérature abonde concernant l’impact de l’indice de masse corporelle (IMC) sur le temps de réaction. Nos résultats n’ont pas permis d’appuyer la littérature existante car aucune corrélation n’a été obtenue entre l’IMC et le TRS chez nos adolescents en effectuant une corrélation linéaire de Pearson. Le phénomène de diminution du TRS, au cours de l’adolescence, peut s’expliquer par la maturation du SN. D’autres études seront nécessaires pour valider l’absence de lien entre le TRS et le sommeil ainsi que l’IMC.
