Full textAngélique (Dicorynia guianensis Amsh.) is a tree species in French Guiana that is heavily exploited for its wood, but it is known to have variable natural durability, which can be of severe consequences for the user. In this thesis we wanted to understand the origin of the natural durability of Angelique heartwood in order to understand its variability, to beter predict it. This multidisciplinary work combines wood sciences, natural products chemistry and microbiology. First, we implemented a sampling strategy based on the architectural profile of tree individuals to understand the variability of natural durabilityn which was confirmed by biological assays. We then assessed the influence of potential natural durability factors that we measured in the wood samples. As such, the role of metabolies was investigated using targeted and untargeted metabolomics, coupled with a dereplication strategy. Lignin and infradensity have also been tested as factors of durability for Angelique heartwood. Finally, factors that are related to tree ontogeny have been taken into account and the results highlight the importance of the stage development and the environment of tree individuals. Lastly, we have proposez esasy, fast and reliable spectroscopie tools (medium and near infrared) to predict the nartural durability. These results are encouraging and suggest their potential use by the timber industry to predict durability of Angélique heartwood

Full textIn this thesis, we focus on the variations induced by different analysis methods, also known as analytical variability, in brain imaging studies. This phenomenon is now well known in the community, and our aim is now to better understand the factors leading to this variability and to find solutions to better account for it. To do so, I analyse data and explore the relationships between the results of different methods. At the same time, I study the constraints related to data reuse and I propose solutions based on artificial intelligence to build more robust studies

Full textL'approche 1D développée pour les modèles simplifiés consiste à exprimer la température en un point de la surface du sol avec relief comme une combinaison d'une température "ombre" et d'une température "soleil" du sol équivalent plat horizontal. Les phénomènes prépondérants de la variabilité de la température sont isolés par la réalisation de mesures en extérieur sur une maquette à profil sinusoïdal. Les mesures obtenues permettent de valider le code thermique 3D de référence.
Différents modèles analytiques 1D sont développés et validés par rapport à ce code. L'application de la méthode "ombre/soleil" par passage dans l'espace de Fourier conduit à une bonne concordance entre le modèle et la solution de référence 3D.

Full textThis work focuses on the study of the inter and intra specific variability of the extractives substances of the barks of Abies alba, Picea abies, Pseudotsuga menziesii, Quercus robur and Fagus sylvatica. New knowledge about the variability in chemical composition of different bark types can be used as a support decision tool for a future industrial valorization, which would bring an added value to the wood industry. Thus, the constituents of the bark are separated into two categories with the polyphenols which were analyzed mainly from the water/ethanol extracts and the biopolymers which were extracted from the bark residues from the successive extractions. For the water/ethanol extractions (1:1), 5 species with 8 trees per species and more than 10 heights per tree were extracted. An increase of extractives rates with height was observed for softwoods and from these results it appears that softwoods contain more extractives than hardwoods and that the amount of extractive increases with height. For the successive extractions with the toluene / ethanol mixture (2:1), then with the ethanol (100%), only 4 trees by essence were extracted because it was essentially a question of recovering bark devoid of extractives in view of analyze biopolymers. Subsequently, the bark extracts were studied using complementary analytical methods such as LC-UV-MS, GC-MS, IR, 1H NMR, MALDI-TOF, SEC as well as specific tests to determine the levels. total phenols, holocellulose, α-cellulose, hemicellulose, lignin, suberin and ash. The results demonstrate the existence of variability in the chemical composition of softwood bark as a function of height: the levels of polyphenols, suberin, lignin and holocellulose decrease with height while the levels of terpenes and ash increase. with height. Using the same analytical protocol, significant inter-tree variability was demonstrated for hardwood bark. Some observed differences have been explained by biological parameters such as height, age of tissues, bark storage conditions or even different allometry between trees
