In this Research Topic we report advances in fundamental and applied aspects of the perennial C4 bioenergy crop Miscanthus (Miscanthus spp.) and its role in mitigating climate change as part of the bioeconomy. Miscanthus is extremely well suited for bioenergy, biofuel and bioproduct production over a wide geographic area including Europe and North America as well as its native Asia.
Miscanthus offers a unique perspective within plant science: the challenge is to domesticate this novel crop for diverse environments and uses while simultaneously developing sustainable value chains to displace fossil fuels and contribute to climate change mitigation. Contributions to this Research Topic were offered from leading Miscanthus researchers from different parts of the world. We accepted 16 articles from 95 authors, which have generated 21,161 views at March 26 2018. Nine of the articles are the output of the European FP7 OPTIMISC project and describe multiple experiments investigating a common set of Miscanthus genotypes in Europe and Asia. These papers are complemented by seven additional articles from global authors, providing a comprehensive analysis of the state of the art of Miscanthus research and application.

The master thesis will be focused on the recycling process of data servers. In the framework of an Interreg project, the recycling process of data servers will be assessed as the environmental impacts associated to the process. The phases of dismantling and shredding will be studied, characterizing the input and output materials. During the process, data will be collected in order to carry out a screening lca study on the process to provide recommendations on the design of further servers and on the design of the process to optimize the recovery of raw materials and minimize the environmental impacts.

This master's thesis is focus on the analysis of a specific type of fertilizer, that is produced by the company Prayon on its Engis site. This company is specialized in the production of phosphoric acid. This fertilizer is called NP 12-27 for 12% of ammonia and 27% of P2O5. It is produced by using phosphoric acid, MARP (monoammonium residual phosphate, a co-ptoduct of phosphoric acid). The first two are produced by Prayon, whereas ammonia is brought at another company. These three raw materials are mix together to synthesis the fertilizer. Due to the growing preoccupation about the environment and to the population growth that increase the food need and also the demand of fertilizers, having a clear understanding of the environmental impact of the production of NP 12-27 is important. Therefore, it has been analysed using the LCA method. LCA identifies and quantifies the energy and materials used and wastes released to the environment and assesses the impact of those inputs and outputs. The results have been calculated with the CML method. This analysis was compared to another LCA performed with the ReCiPe method to check the robustness of the results. Different types of allocations were carried out on a specific type of by-product called MARP. Thanks to this LCA, it was found that the elements with the greatest environmental impact are primarily ammonia over the abiotic depletion (fossil fuel) and the global warming. This is the only elements that does not come from the company. The second element having the greatest impact is the MARP of Puurs, especially in abiotic depletion, marine ecotoxicity and eutrophication The NP 12-27 can be of great interest, because, compared to another fertiliser taken into the ecoinvent database, it has less impact over nearly all the impact category except the eutrophication where the impact is bigger. The main advantage of this fertiliser is that it enhances the value of a product which was not very useful.

Dans ce travail, l’accent va être porté sur une population lésée ainsi que sur les impacts qu’une lésion a pu avoir sur leur mémoire. On s’intéressera aux processus de segmentation, de binding et de compression temporelle. On évoquera également les limites actuelles des tests utilisés pour évaluer la mémoire épisodique. Une méthodologie incluant de nouvelles tâches plus écologiques sera au cœur de ce mémoire. Chaque année, de nombreuses personnes dans la population mondiale sont victimes d’une lésion cérébrale acquise (LCA). On constate que les LCA ont un impact sur la cognition dont la mémoire qui constituera le point central de cet écrit. La mémoire est une fonction cognitive qui permet d’encoder, de stocker et de récupérer des informations. L’encodage transforme une perception sensorielle en une trace mnésique. Le stockage peut se définir comme étant un procédé permettant le maintien d’une information en mémoire à court ou à long terme. La récupération permet à la personne de rappeler des informations précédemment encodées et stockées. La mémoire n’est pas une fonction unique mais bien un système complexe comprenant plusieurs sous-systèmes : la mémoire sensorielle, la mémoire à court terme, la mémoire à long terme comprenant la mémoire épisodique, sémantique, procédurale, le conditionnement classique et l’amorçage. Les précédents travaux et études ont permis de mettre en lumière les différentes composantes anatomiques du lobe temporal médian (ex : hippocampe). Les lobes frontaux sont essentiels dans le processus de récupération. Les impacts survenant à la suite d’une lésion sont fortement dépendants de la localisation de la lésion dans le cerveau. Trois processus sont intégrés dans la mémoire épisodique : la segmentation qui permet de diviser une activité, le binding qui regroupe plusieurs éléments épisodiques et la compression qui permet de condenser la durée réelle d’un évènement. A l’heure actuelle, les tests utilisés pour évaluer cette dite mémoire ne sont pas des plus écologiques. Une tâche va tenter de résoudre ce problème : la tâche d’évènements quotidiens utilisant une méthode innovante, l’Event Sampling Method (ESM). Lors des analyses réalisées, très peu de résultats ressortent significatifs. On peut juste évoquer un lien entre la richesse des souvenirs quotidiens et le moment où le sujet appuie pour diviser la vidéo en différentes actions ayant du sens pour lui. Suite à cette étude, on peut conclure que la méthodologie utilisée est innovante malgré quelques petits défauts à ajuster et que ce travail servira de tremplin à d’autres recherches tout aussi intéressantes sur le domaine.
