Water-surfaces profiles of gradually varied flow in prismatic channels with variable slope

, 2007
The change from subcritical to supercritical linear flow in prismatic channels with constant slope is gradual and spontaneous only in the presence of a critical slope. Yet, generally, such changes occur when channel’s slope varies. When this happens, the

Continuous Sewing Machine‐Like Suture Provides Higher Failure and Yield Load Compared to Traditional Techniques for Meniscal Root Repair in a Biomechanical Porcine Model

Arthroscopy, EarlyView.
Purpose To evaluate the biomechanical performance of the sewing machine‐like suture (SMS) technique against three established techniques (two cinch‐loop (TCL), modified Mason‐Allen (MMA), and double Mason‐Allen (DMA)) for transtibial pull‐out repair of posterior medial meniscal root tear (PMMRT) in a porcine model.

Scattering of gravity waves in subcritical flows over an obstacle

, 2016
International audienceWe numerically study the scattering coefficients of linear water waves on stationary flows above a localized obstacle. We compare the scattering on trans- and subcritical flows, and then focus on the latter which have been used in ...

Engineering Biochar‐Derived Functional Materials for High‐Performance Supercapacitors: Design Principles, Mechanisms, and Scalable Strategies

Carbon Energy, EarlyView.
ABSTRACT Biochar has emerged as a useful and adaptable source of carbon for supercapacitor electrodes. Its value comes from the way biomass chemistry, thermal conversion, and activation conditions shape the resulting pore network, surface groups, and degree of carbon ordering.
