Scour Characteristics and Bearing Capacity Response of MGB Hybrid Foundations in Offshore Wind Applications

Journal of Marine Science and Engineering
Scour at offshore wind turbine foundations compromises their structural stability. This study investigates scour characteristics and their impact on the ultimate bearing capacity of a novel Monopile-Gravity-Bucket (MGB) hybrid foundation.

Tip-Bed Velocity and Scour Depth of Horizontal-Axis Tidal Turbine with Consideration of Tip Clearance

Energies, 2019
The scouring by a tidal turbine is investigated by using a joint theoretical and experimental approach in this work. The existence of a turbine obstructs a tidal flow to divert the flow passing through the narrow channel in between the blades and seabed.

Response mechanism of ice floods to scour and silting evolution in the Inner Mongolian channel and reaches of the Upper Yellow River

Shui kexue jinzhan, 2021
The alluvial river flooding problem in Inner Mongolia is prominent along the upper reaches of the Yellow River. Studying the scour and silting evolution of the river and the response mechanism of the floods can provide technical support for flood ...

Dynamic Self‐Clickable Decellularized Matrix Hydrogels for Regulating Vascularity and Enhancing Muscle Regeneration

Advanced Science, EarlyView.
Dynamic decellularized hydrogels are prepared using bovine decellularized small intestine submucosa (SIS) norbornene (dSIS‐NB). Bovine dSIS contained significant amounts of disulfide‐rich fibrillin‐I, enabling ‘self‐clickable’ thiol‐norbornene gelation and spatiotemporal tuning of hydrogel physicochemical properties.

The Spatiotemporal Genetic Architecture of Seed Vigor in Upland Cotton

Advanced Science, EarlyView.
Leveraging the semi‐automated SeedRanger platform, we profiled the germination kinetics of 356 cotton accessions at a 30‐min interval. This high‐throughput phenomic approach delineated a temporal genetic network comprising 541 stage‐specific loci. Crucially, functional validation identified FLA2 as a pivotal, auxin‐modulated regulator that orchestrates

Scour downstream of a block ramp in asymmetric stilling basins [PDF]

, 2008
Block ramps are hydraulic structures generally used in mountains rivers. In the last decades they have become more common in river restoration as they minimize the environmental impact.

Numerical Investigation of Local Scour Around Bridge Pile-Group Foundations Under Steady Flows

Infrastructures
Local scour around pile-group foundations is a predominant cause of hydraulic instability in bridge engineering. This study employs a fully coupled three-dimensional computational fluid dynamics model to investigate local scour around a 2 × 2 inline pile

Challenges and enablers in fluidization technology

AIChE Journal, EarlyView.
Abstract Gas–solid fluidized beds provide excellent heat and mass transfer for high‐throughput operations from coating to catalytic conversion and underpin emerging low‐carbon technologies. Yet industrial reliability, scale‐up, and control lag scientific understanding, particularly as finer, stickier, and more variable feedstocks increasingly challenge
