Composition et cognition musicales : création, perception, appréciation

2005

Ce texte est un rapport de fin de recherche issu de l'ACI cognitique.; Ce projet avait pour objet d'apporter des éléments objectifs de réflexion sur les possibilités et limites de la perception et de la compréhension des matériaux et des structures d'une oeuvre de musique contemporaine. Les buts spécifiques comprenaient l'étude : 1) des processus d'invention et de résolution de problèmes dans la composition musicale, 2) des processus de traitement perceptif et de mémorisation des matériaux musicaux, 3) du traitement perceptif et mnésique des variations ou transformations opérées sur ces matériaux et de l'intégration des matériaux et de leurs transformations dans une forme d'ensemble, 4) du …

Sphères privée et professionnelle chez les enseignants du premier degré : comment priorisent-ils ?

2019

Private and professional lives among primary teachers: how they prioritize? Being a teacher in primary school seems far from allowing the articulation of work and private life in such a comfortable manner as seen in collective beliefs. In order to deconstruct the belief considering teachers as privileged, this contribution proposes, based on empirical results (an online survey with 21,642 responses), to report, first, how primary teachers prioritize their private or professional lives. Second, this paper highlights the reasons which lead them to favour one of the two fields, notably when priority is given to private life at the expense of professional life. Referring to the issue of work-fa…

Retour en formation et parcours d'études atypiques : déterminants et valorisation sur le marché du travail

2019

Life long learning appears as a major concern for our societies. After leaving the educational system, learning can imply returning to school or continuing education. Academic careers in France seem less and less linear. Young peopleare encouraged to make the most of college breaks in order to diversify their experiences. During their career, they are to be trained to « be free to choose their professional future », as mentions a new law. This thesis, then, aims atidentifying the reasons why people go back to training and at stuying how such returns are seen by the labor market.This work includes a preliminary chapter and three other chapters, each with specific data. Based on a literature …

Family Matters : Abusing Family Refresh Tokens to Gain Unauthorised Access to Microsoft Cloud Services Exploratory Study of Azure Active Directory Fa…

2022

Azure Active Directory (Azure AD) is an identity and access management service used by Microsoft 365 and Azure services and thousands of third-party service providers. Azure AD uses OIDC and OAuth protocols for authentication and authorisation, respectively. OAuth authorisation involves four parties: client, resource owner, resource server, and authorisation server. The resource owner can access the resource server using the specific client after the authorisation server has authorised the access. The authorisation is presented using a cryptographically signed Access Token, which includes the identity of the resource owner, client, and resource. During the authorisation, Azure AD assigns Ac…

Synthesis and biological evaluation of new bicyclic fluorinated uracils through ring-closing metathesis.

2006

Two families of bicyclic fluorinated uracils have been prepared starting from a gem-difluorinated unsaturated nitrile, by means of a ring-closing metathesis reaction to form the new ring, which is fused at the C-5/C-6 or N-1/C-6 positions of the uracil moiety. The selective formation of olefin regioisomers in the metathesis process can be controlled according to the reaction conditions (catalyst, solvent, and temperature). The acaricidal activities of the resulting compounds have also been investigated.

Optimization of acetate production from citrus wastewater fermentation

2021

Abstract Citrus wastewater is a sugar-rich waste stream suitable for the recovery of energy of material from its treatment. In this study, fermentation of citrus wastewater was carried out to assess the optimal conditions to maximize the bioconversion of the organic substrate into acetate. Unbalanced nutrient (C: N: P 200:0.1:0.1) enabled the highest acetate production. The presence of the particulate organic fraction enabled to obtain a higher acetate concentration regardless the initial COD concentration. Initial pH values higher than 5 did not cause substantial differences on the maximum bioconversion of COD into acetate in Trial 3, whereas pH lower than 5 hindered the hydrolysis process…

Catalytic valorisation of Chlorella sp. algae to obtain 5-Hydroxymethylfurfural in the presence of Nb2O5 or NbOPO4

2023

Microalgae are interesting biomass able to growth in not-arable lands, in wastewaters or seawaters. There are plenty of species of microalgae and several of them find application in various industrial sectors because they are source of several products in an integrated biorefinery view. In this work two acidic heterogeneous catalysts, namely Nb2O5 and NbOPO4 have been used. Both are commercial products provided by CBMM and they have been physico-chemically characterised. The isomerisation/dehydration reactions proceed through a tandem pathway involving the Lewis and Brønsted acid sites provided by the surface of the acidic solids giving rise to the isomerization of glucose to fructose, foll…
