River Research and Applications, EarlyView.ABSTRACT As ecosystem engineers, beavers (Castor canadensis) modify river corridor form through dam building. When beavers are removed from a river corridor, their unmaintained dams wash out, altering the stream's hydrologic regime. The assumption that beaver dams increase floodplain connectivity is frequently presumed but has not been directly ...

Review of Zeeman Effect Observations of Regions of Star Formation
Frontiers in Astronomy and Space Sciences, 2019 The Zeeman effect is the only observational technique available to measure directly the strength of magnetic fields in regions of star formation. This chapter reviews the physics of the Zeeman effect and its practical use in both extended gas and in ...

Redistributive effects of unsteady flow regimes downstream of reservoirs
River, EarlyView.Abstract Understanding unsteady flow regimes in river channels downstream of a reservoir, is essential for predicting and regulating water level and flow velocity in the lower basin. Using hourly observations of discharge and water level at Xiangjiaba Station from 2018 to 2022, an evaluation indicator was proposed to analyze unsteady flow regimes ...

Numerical Investigation on a Flash Flood Disaster in Streams with Confluence and Bifurcation
, 2022 On 20 August 2019, a flash flood occurred in Sanjiang Town, Sichuan, China, and caused great damage to people living there. The town lies at the junction of five streams, with streams A, B, and C combining at the town and further dividing into streams D ...

Improving fatigue resistance of translucent 4Y‐PSZ zirconia through glass gradation
European Journal of Oral Sciences, EarlyView.Abstract To evaluate the effect of graded glass infiltration on the fatigue behavior and mechanical reliability of translucent 4Y‐PSZ zirconia before and after hydrothermal aging, disc‐shaped specimens were fabricated by uniaxial pressing and divided into control and glass‐graded groups (n = 36/group).
