Diversity and phylogeography of Southern Ocean sea stars (Asteroidea)

2019

How is life distributed on the Southern Ocean sea floor? How can we explain species distribution patterns, their origin and the underpinning drivers? These questions are central to macroecological studies, especially in regions facing fast environmental changes. The main objective of this thesis was to describe and characterise distribution patterns of sea stars species (Echinodermata: Asteroidea) with regards to reproductive strategy (i.e. brooding versus broadcasting), a key life history trait for species dispersal. I tested whether contrasting dispersal abilities between direct developers (brooders) and species with pelagic larvae in their development (broadcasters) result in distinct di…

Infrastructures agroécologiques en droit

2017

International audience; Les infrastructures agroécologiques (IAE) sont une notion récente désignant des éléments naturels, culturels et paysagers, tels les mares, les landes, les haies, les talus, les fossés, les arbres, les bosquets, les bandes enherbées le long des cours d’eau, les murets de pierre ou encore les terrasses. Pendant des siècles, ces milieux physiques sont passés inaperçus pour le droit. Attachés au foncier, ils n’en constituaient qu’un accessoire sommé de suivre le régime juridique du principal. Ces infrastructures étaient sous l’entière maîtrise du propriétaire immobilier pouvant, à sa guise, les créer ou les faire disparaître. Leur statut a cependant c…

Droit et philosophie à la lumière de l'Encyclopédie

2015

International audience; Quelle place occupe le droit dans l’Encyclopédie de Diderot et de D’Alembert ? Quels rap­ports le mou­ve­ment ency­clo­pé­di­que et l’esprit de la Déclaration des droits de 1789 entre­tien­nent-ils ? Dans cette étude nova­trice, Luigi Delia explore les enjeux du droit dans l’entre­prise emblé­ma­ti­que des Lumières.Encadrée par la publi­ca­tion de deux ouvra­ges fon­da­men­taux – L’Esprit des lois de Montesquieu (1748) et le Traité des délits et des pei­nes de Beccaria (1765) –, l’Encyclopédie pro­pose une nou­velle concep­tion de la jus­tice en fai­sant dia­lo­guer des cultu­res juri­di­ques dif­fé­ren­tes, celle des juris­tes et celle des phi­lo­so­phes.

Coscinolactams A and B: new nitrogen-containing sesterterpenoids from the marine sponge Coscinoderma mathewsi exerting anti-inflammatory properties

2009

Abstract Investigation of the marine sponge Coscinoderma mathewsi led to the isolation of two novel nitrogen-containing cheilanthane sesterterpenoids, coscinolactams A and B, together with known suvanine. The structures were elucidated by extensive spectroscopic measurements including NOE experiments to deduce the stereochemistry. The natural compounds, as well as a semisynthetic derivative, showed moderate anti-inflammatory activity measured as their capability to inhibit PGE2 and NO production. The suvanine aldehyde derivative 4 inhibited inducible nitric oxide protein expression with an IC50 value of 7.3 μM.

Conséquences des variations de teneur en sel, sucre, et matière grasse sur les préférences et les consommations alimentaires des enfants

2011

Background: In France, the National Nutrition and Health Programme (“Programme National Nutrition Santé” or “PNNS”) is in charge of implementing the recommendations aiming at reducing salt, sugar and fat quantities in foods. However, the extent to which this might impact children’s food preferences and intake is limited. Objective: The present work aimed at understanding the impact of varying salt, sugar and fat variations in foods, on toddlers and children’s food preferences and intake. Methods: Studies were conducted in toddlers’ and children’s natural eating environment (nursery and school canteen), at their usually scheduled lunch and/or snack times. Results: Concerning sucrose, the add…

Strong Instability of Ground States to a Fourth Order Schrödinger Equation

2019

Abstract In this note, we prove the instability by blow-up of the ground state solutions for a class of fourth order Schrödinger equations. This extends the first rigorous results on blowing-up solutions for the biharmonic nonlinear Schrödinger due to Boulenger and Lenzmann [8] and confirm numerical conjectures from [1–3, 11].

Superior Fischer-Tropsch performance of uniform cobalt nanoparticles deposited into mesoporous SiC

2020

Electrochemically-derived well-crystalline mesoporous silicon carbide (pSiC) was used as a host for cobalt nanoparticles to demonstrate superior catalytic performance during the CO hydrogenation according to Fischer-Tropsch. Colloidal Co nanoparticles (9 ± 0.4 nm) were prepared independently using colloidal recipes before incorporating them into pSiC and, for comparison purposes, into commercially available silica (Davisil) as well as foam-like MCF-17 supports. The Co/pSiC catalyst demonstrated the highest (per unit mass) catalytic activity of 117 µmol.g(CO)-1.g-1(Co).s-1 at 220 °C which was larger by about one order of magnitude as compared to both silica supported cobalt catalysts. Furthe…

Les catastrophes naturelles au Moyen Âge (XIIe-XVe siècle)

2017

International audience; Catastrophe : le terme renvoie dans nos représentations contemporaines à des images de destruction, de désorganisation sociale et éventuellement de mort de masse. Les événements tels que les inondations, les tremblements de terre, les tempêtes, etc., sont inévitablement pensés sur le mode du drame et de la tragédie. Viennent à l'esprit la nécessité de comprendre l'événement à travers un bilan des pertes matérielles et surtout humaines, la détresse des populations sinistrées, le devoir gouvernemental et non-gouvernemental de développer l'aide humanitaire, et le nécessaire travail de mémoire d'un malheur collectif. C’est en considérant ce faisceau de réaction en tant q…
