Empirical Formulas to Predict the Maximum Scour Depth With Debris Accumulation Around A Single Cylindrical Bridge Pier: An Experimental Study [PDF]

Engineering and Technology Journal, 2020
The probability of debris accumulation near bridge piers during the heavy storm and river flood convert the hydraulic action of flow and increase the scour depth due to the reduction of flow area and the increase in velocity of flow.

Maximum Abutment Scour Depth in Cohesive Soils [PDF]

Scour and Erosion, 2010
Most conventional methods to predict the depth of abutment scour were developed with flume test results using cohesionless soils, and those methods have been used to the abutment scour depth prediction in cohesive soils. Generally floodplains where most abutments are located are composed of less erodible soils such as cohesive soils.

Beyond the Gold Standard: Towards Industrially Viable Electrodes for Durable Perovskite Solar Cells

Advanced Energy Materials, EarlyView.
Transparent and opaque electrode materials are mapped by raw material cost per 1 m2 electrode area and retained median device efficiency after heat–light ageing. FTO offers a lower‐cost and more stable alternative to ITO, while Cr/Al provides the lowest‐cost rear electrode investigated with Au‐like stability and substantially improved durability ...

Hydrodynamic Modeling and Comprehensive Assessment of Pier Scour Depth and Rate Induced by Wood Debris Accumulation

Hydrology
This study mainly investigates the impact of debris accumulation on scour depth and scour hole characteristics around bridge piers. Through controlled experiments with uniform sand bed material, the influence of various debris shapes (high wedge, low ...

Revisiting paravertebral muscles in European rabbits (Oryctolagus cuniculus) and European brown hares (Lepus europaeus) (Leporidae; Lagomorpha)

The Anatomical Record, EarlyView.
Abstract Domesticated European rabbits (Oryctolagus cuniculus) have long been chosen as laboratory model organisms. Despite this, there has been no definitive study of the vertebral musculature of wild rabbits. Relevant descriptions of well‐studied veterinary model mammals (such as dogs) are generally applicable, but not appropriate for a species ...

Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection

Archaeological Prospection, EarlyView.
ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...

Research on Identification Method of Scour Depth for Bridge Based on ERA and SVM

Shock and Vibration, 2015
A new damage identification method for bridge scour was proposed, in the case that it was difficult to detect bridge scour depth applying testing equipment.

Simplified analysis of dynamic response of pile-supported bridge under local scour and verification by centrifugal shaking tests

Yantu gongcheng xuebao, 2021
Scour causes the erosion of soil, changes the seismic response of site, and also influences the seismic properties of bridge. To investigate the dynamic behavior and damage potential of pile-supported bridges at local scour site, the effects of scour on ...

Scour depth downstream sharp-crested weir

Journal of Engineering and Applied Science, 2023
AbstractWeirs are hydraulic obstructions constructed across an open-channel flow causing a rise in water which is useful to convert water to the channels upstream as well as using these structures as a measuring device. There are different types, and a sharp-crested weir is one of them.

Purification of Advanced Therapeutics by Flow‐Through Pseudo‐Affinity Chromatography: Bi‐Specific mABs, Fc Fusion Proteins, and Adeno‐Associated Viruses

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Modern biopharmaceutical manufacturing requires purification platforms capable of processing structurally and functionally diverse products while addressing the challenge of removing persistent and high‐risk host cell proteins (HCPs).
