Turbulence Intermittency Effects on the Initiation Threshold of Sediment Motion in Natural Waters

Water Resources Research
The initiation threshold of sediment motion, a key component in quantifying sediment transport, has potential link to intermittent turbulence bursts. Here, we elaborated in situ experiments on coastal sea bottom covered with cohesive sediments, to obtain

Investigating the corrosion mechanism of AZ31 alloy bimodal microstructure by the quasi-in-situ EBSD characterization and DFT calculation

Journal of Materials Research and Technology
The grain characteristic and orientation were analyzed using the electron backscatter diffraction (EBSD) for AZ31 hot-rolled alloys. The corrosion initiation of the bimodal microstructure is revealed for the hot-rolled AZ31 alloys obtained by the quasi ...

Influence of Inhomogeneous Plastic Strain and Crystallographic Orientations on Fatigue-Induced Dislocation Structures in FCC Metals

Metals
Owing to the differences in crystallographic orientations among individual grains, dislocation structures in polycrystals are inherently inhomogeneous from grain to grain.

Developing a partcipatory approach to seed production and varietal selection [PDF]

, 2006
The performance of UK winter wheat varieties was tested under organic conditions involving farmer participation. Three breadmaking varieties (Hereward, Solstice and Xi19) and their mixture (1:1:1) were grown at 19 UK farms in 2003/04 and 2004/05.
