Séminaire PMMH - Sara Puijalon (LEHNA – CNRS, Université Claude Bernard Lyon 1)
Interactions between submerged aquatic vegetation and flow : applications of ecohydraulics and biomechanics to ecological questions
Interactions between submerged aquatic vegetation and flow in rivers and streams are complex. Flowing water induces hydrodynamic stress on aquatic plants colonizing these habitats, which can, in some cases, cause mechanical failures such as breakage and uprooting. Additionally, aquatic plant beds have a significant impact on their physical habitat by deflecting flow and modifying water velocity and turbulence. This talk will present research on the interactions between aquatic vegetation and flow. It will cover hydrodynamic and biomechanical responses of plants to flow, at both the individual plant and patch scale. It will also present how aquatic vegetation modifies flow conditions and contributes to the functioning of flowing ecosystems.

Vendredi 17 mai de 11h00 à 12h00 - Salle réunion PMMH 1
What we know and don't know about the ocean circulation and ice melting around Antarctica
The Antarctic ice sheet is losing mass increasingly rapidly and could contribute several tens of centimetres of sea-level rise by 2100. In this presentation I will review our understanding of the southern ocean circulation, which (we know) is controlling ice melting around Antarctica and driving the retreat of the (...) -

Earthquake statistical properties : an explanation for the distribution of magnitude and for the existence of aftershocks
Earthquakes in nature follow several statistical properties. In particular, the distribution of energy released by an earthquake (Gutenberg-Richter's law) and the frequency of aftershocks after a large event (Omori's law) are both power-laws. By studying several earthquake models, we have shown that the (...) -

1D confinement controls cell shape and migration
Pericytes are mural cells of the microvasculature, they wrap around small vessels, support the vessels mechanically and participate in blood flow regulation. Pericytes are distinguished by two main characteristics ; first their distinct morphology, which has been likened to a “bump on a log”, as they present long (...)
The audience is composed of people with rather heterogeneous backgrounds including specialists in solids, fluids, granular flows, statistical physics... so the idea is to keep your talk understandable by people not necessarily working in your field... The seminar time slot runs from 11am to noon so the best is to make the talk last around 45 minutes to leave some time for discussion.
