Optimum control strategies for maximum thrust production in underwater undulatory swimming

Autor: fu, L., Israilov, S., Rodriguez, J. Sanchez, Brouzet, C., Allibert, G., Raufaste, C., Argentina, M.

Fishes, cetaceans, and many other aquatic vertebrates undulate their bodies to propel themselves through water. Swimming requires an intricate interplay between sensing the environment, making decisions, controlling internal dynamics, and moving the

Taylor-like vortices in the shear-banding flow of giant micelles

Autor: Fardin, M. A., Lasne, B., Cardoso, O., Gregoire, G., Argentina, M., Decruppe, J. P., Lerouge, S.

Using flow visualizations in Couette geometry, we demonstrate the existence of Taylor-like vortices in the shear-banding flow of a giant micelles system. We show that vortices stacked along the vorticity direction develop concomitantly with interfaci

Interface dynamics in shear-banding flow of giant micelles

Autor: Lerouge, S., Fardin, M. A., Argentina, M., Gregoire, G., Cardoso, O.

We report on a non trivial dynamics of the interface between shear bands following a start-up of flow in a semi-dilute wormlike micellar system investigated using a combination of mechanical and optical measurements. During the building of the bandin

Interface instability in shear banding flow

Autor: Lerouge, S., Argentina, M., Decruppe, J. P.

We report on the spatio-temporal dynamics of the interface in shear-banding flow of a wormlike micellar system (cetyltrimethylammonium bromide and sodium nitrate in water) during a start-up experiment. Using the scattering properties of the induced s

Outcomes from a Zoonotic Disease Prioritization workshop using One Health approach in Mozambique, 2018 to 2023

Publikováno v: One Health Outlook, Vol 6, Iss 1, Pp 1-9 (2024)

Abstract Introduction Around 75% of (re)emerging infections are of zoonotic origins. The risk of zoonotic transmission in Mozambique is high because approximately 81% of the country’s labor force is involved with agriculture, which represents a vul
