A QM/MM Approach Using the AMOEBA Polarizable Embedding: From Ground State Energies to Electronic Excitations

2016

International audience; A fully polarizable implementation of the hybrid Quantum Mechanics/Molecular Mechanics approach is presented, where the classical environment is described through the AMOEBA polarizable force field. A variational formalism, offering a self-consistent 1 relaxation of both the MM induced dipoles and the QM electronic density is used for ground state energies and extended to electronic excitations in the framework of Time-Dependent Density Functional Theory combined with a state specific response of the classical part. An application to the calculation of the solvatochromism of the pyridinium N-phenolate betaine dye used to define the solvent ET30 scale is presented. Th…

Integrated signaling network involving calcium, nitric oxide, active oxygen species but not mitogen-activated protein kinases in BcPG1-elicited grape…

2006

We have already reported the identification of the endopolygalacturonase 1 (BcPG1) from Botrytis cinerea as a potent elicitor of defense responses in grapevine, independently of its enzymatic activity. The aim of the present study is the analysis of the signaling pathways triggered by BcPG1 in grapevine cells. Our data indicate that BcPG1 induces a Ca2+ entry from the apoplasm, which triggers a phosphorylation-dependent nitric oxide (NO) production via an enzyme probably related to a NO synthase. Then NO is involved in i) cytosolic calcium homeostasis, by activating Ca2+ release from internal stores and regulating Ca2+ fluxes across the plasma membrane, ii) plasma membrane potential variat…

Soil Solarization and Calcium Cyanamide Affect Plant Vigor, Yield, Nutritional Traits, and Nutraceutical Compounds of Strawberry Grown in a Protected…

2019

Soil solarization is a hydrothermal procedure of disinfesting soil of soilborne diseases and pests. Solarization can be combined with many other chemical or non-chemical alternatives to afford integrated pest and diseases management or improve plant yield. Calcium cyanamide (CaCN2) is a fertilizer used in agriculture sector and is also effective in suppressing soilborne pathogens. The present study assessed the influences of different pre-plant CaCN2 dosages on strawberry grown on solarized or non-solarized soil. Soil solarization and 500 kg ha&minus

Extracellular matrix composition defines an ultra-high-risk group of neuroblastoma within the high-risk patient cohort

2016

Background: Although survival for neuroblastoma patients has dramatically improved in recent years, a substantial number of children in the high-risk subgroup still die. Methods: We aimed to define a subgroup of ultra-high-risk patients from within the high-risk cohort. We used advanced morphometric approaches to quantify and characterise blood vessels, reticulin fibre networks, collagen type I bundles, elastic fibres and glycosaminoglycans in 102 high-risk neuroblastomas specimens. The Kaplan-Meier method was used to correlate the analysed elements with survival. Results: The organisation of blood vessels and reticulin fibres in neuroblastic tumours defined an ultra-high-risk patient subgr…

Intérêt du growth differentiation factor 15 (GDF15) comme biomarqueur pronostique après la survenue d'un Accident Vasculaire Cérébral ischémique (AVC)

2018

Introduction Le GDF15 est un biomarqueur de mauvais pronostic dans certaines pathologies cardiovasculaires comme le syndrome coronarien aigu. Son interet dans le domaine de AVC n’a ete que peu etudie a ce jour. Objectifs Notre travail consistait a l’evaluation des taux de GDF15 chez des patients hospitalises a la phase aigue d’un AVC ischemique traites par fibrinolyse et/ou thrombectomie. L’objectif principal etait d’evaluer l’association entre les taux de GDF15 et la recuperation fonctionnelle a 3 mois. Methodes Au total, 174 patients ont ete inclus entre le 16/01 et le 30/09/2017. Le consentement etait recueilli oralement. Des prelevements biologiques ont ete realises a l’admission du pat…

Efficacité interne de l'enseignement primaire aux pays de la Communauté Economique des Pays des Grands Lacs (CEPGL) : question approfondie sur le Rwa…

2011

This PhD study has been achieved with objective to carry out the level of internal efficiency of the primary education in the CEPGL countries and the progress reaches toward the education for all after the period of ethnic and armed conflicts. In addition, specifically for Rwanda, to underline the individual, families and school factors explanatory of the repetition and drop-out in the primary schools. The data of our analysis come from different reports of ministries, international organizations and publications of researchers. The analysis of the primary education inside CEPGL countries, by the indicators that document education supply and demand, show that, after the period of conflicts,…

L'adolescent face à la relation d'emprise scolaire : entre adaptations secondaires et arrangements ordinaires

2009

L’article etudie l’hypothese d’un desir d’emprise au cœur de toute relation pedagogique, et la relation d’emprise, quelle que soit la modalite qu’elle revet, represente une veritable formation defensive, permettant d’occulter le manque devoile par la rencontre de l’autre. De ce scenario, se degagent des regles communes a toutes les relations d’emprise : l’instrumentalisation de l’autre et l’impossibilite pour celui-ci de rompre le cycle d’echange dans lequel il donne plus qu’il ne prend, la rupture etant construite comme de l’ordre de l’injustifiable et supposant un passage en force, un acte de rebellion ou de violence. Comment les adolescents se maintiennent-ils comme sujets desirants dans…

La scolarisation féminine à Djibouti

2012

A la croisée de la sociologie du genre, de la sociologie de l'éducation et de l'anthropologie politique, cette recherche s'intéresse à la complémentarité des approches disciplinaires et méthodologiques au travers d'une étude sur les élèves de Djibouti pour sortir d'une "lecture en négatif" sur la scolarisation des filles limitée en contexte africain. A la suite de ce travail d'immersion sur lequel a reposé cette recherche, ce sont cependant les angélismes qui se cachent derrière la promotion de l'éducation des filles africaines qu'il convient d'interroger et qui donnent à mieux comprendre la persistance des thèses "afropessimistes" dans les rapports d'experts ou la littérature scientifique.

Larisa Maksimova on Implication, Interpolation, and Definability

2018

This edited volume focuses on the work of Professor Larisa Maksimova, providing a comprehensive account of her outstanding contributions to different branches of non-classical logic. The book covers themes ranging from rigorous implication, relevance and algebraic logic, to interpolation, definability and recognizability in superintuitionistic and modal logics. It features both her scientific autobiography and original contributions from experts in the field of non-classical logics. Professor Larisa Maksimova's influential work involved combining methods of algebraic and relational semantics. Readers will be able to trace both influences on her work, and the ways in which her work has influ…
