Websequences, and the influence of subsurface soil water pressures. Of those, the role of surface roughness in soil erosion is perhaps one of the most vexing problems. The conventional wisdom has been to assume that surface roughness increases the resistance of soil to detachment by raindrop impact Moldenhauer and Kemper, 1969; Farres,Ž WebResults show that initial surface roughness has big influence on the wettability of the resulting surface, as well as inducing small variations on the orientation of the generated LIPSS. Structures generated with a higher integrated fluence have also shown to enhance cell differentiation while reducing bacterial activity, making them a great candidate for …

In fact, … WebApr 14, 2024 · The effects of varying the burial level of the mussel, the discharge through the two mussel siphons, and the bed-roughness height are investigated. Increasing the bed roughness produces significant differences in the flow field, turbulence structure, and drag force compared to a smooth bed
WebThe prediction is R t = (1 − mσλ) −½ (1 + mβλ) −½, where β is the ratio of the drag coefficient of an isolated roughness element on the surface to the drag coefficient of the substrate … WebJul 15, 2013 · The effects of H were shown to have a significant influence on the conductivity for both metallic and semiconducting films [4], [43]. Among the three surface roughness parameters (Δ, l and H), the main interplay of the roughness effect occurs for H and l. The parameter Δ has a trivial effect on the conductivity because of the form σ ∼ Δ ...
