The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces

open access: yesGeophysical Monograph Series, Page 229-246., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Demixing and orientational ordering in mixtures of rectangular particles [PDF]

open access: yes, 2007
Using scaled-particle theory for binary mixtures of two-dimensional hard particles with rotational freedom, we analyse the stability of nematic phases and the demixing phase behaviour of a variety of mixtures, focussing on cases where at least one of the

Bulk inhomogeneous phases of anisotropic particles: A fundamental measure functional study of the restricted orientations model [PDF]

open access: yes, 2004
The phase diagram of prolate and oblate particles in the restricted orientations approximation (Zwanzig model) is calculated. Transitions to different inhomogeneous phases (smectic, columnar, oriented, or plastic solid) are studied through minimization ...

Collectifs logistiques et territoires dans les circuits courts alimentaires de proximité : la robustesse de la coopération analysée au prisme des communs

open access: yesDéveloppement Durable et Territoires, 2021
New collectives are identified in the short food supply chains. Their goal is to organize local products supply at a territorial scale. We consider them new because they do not lie on previous social capital and they imply new actors to collaborate with.

La localisation urbaine : atout ou contrainte pour la logistique de l’agriculture urbaine ? Etude de cas à Paris

open access: yesTerritoire en Mouvement, 2022
The strong development of urban agriculture in recent years raises many questions about the viability and sustainability of these projects. One of the issues underlying this sustainability is the distribution of food produced in the inner city.
