Flow and Turbulence driven Water Surface Roughness and Gas Exchange Velocity in Streams
E3S Web of Conferences, 2018 Gas exchange velocity in streams and rivers controls fluxes of atmospheric gases across the air-water interface and is commonly related to the turbulence at the water side. Similarly, river flow hydraulics influences the water surface roughness, which is

Exploiting LSPIV to assess debris-flow velocities in the field [PDF]
Natural Hazards and Earth System Sciences, 2018 The assessment of flow velocity has a central role in quantitative analysis of debris flows, both for the characterization of the phenomenology of these processes and for the assessment of related hazards. Large-scale particle image velocimetry (LSPIV)

Analysis of the Velocity Distribution in Partially-Filled Circular Pipe Employing the Principle of Maximum Entropy. [PDF]
PLoS ONE, 2016 The flow velocity distribution in partially-filled circular pipe was investigated in this paper. The velocity profile is different from full-filled pipe flow, since the flow is driven by gravity, not by pressure.

Thick surface flows of granular materials: Effect of the velocity profile on the avalanche amplitude [PDF]
Physical Review E, 1999 A few years ago, Bouchaud al. introduced a phenomenological model to describe surface flows of granular materials [J. Phys. Fr. I, 4, 1383 (1994)]. According to this model, one can distinguish between a static phase and a rolling phase that are able to exchange grains through an erosion/accretion mechanism. Boutreux et al. [Phys. Rev. E, 58, 4692 (1998)

Shui kexue jinzhan, 2017 We propose a new method for reconstructing complex surface velocity field in weir flow which is notoriously difficult to measure due to its sharp drop and high fluctuation. The new method is able to map the curved flow surface by two coplanar cameras and

Effect of Crest Roughness on Flow Characteristics over Circular Weirs [PDF]
Civil Engineering Infrastructures Journal, 2013 Different construction materials with different roughness used to make circular weirs highly affect surface roughness and, in turn, flow hydraulics passing over these structures.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

FEBS Letters, EarlyView.The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...
