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 ...

Experimental and numerical investigation of the effect of different shapes of collars on the reduction of scour around a single bridge pier. [PDF]

PLoS ONE, 2014
The scour phenomenon around bridge piers causes great quantities of damages annually all over the world. Collars are considered as one of the substantial methods for reducing the depth and volume of scour around bridge piers.

Reducing Scour around Semi-Elliptical Bridge Abutments: Application of Roughness Elements

Fluids, 2023
Bridge abutments in river channels induce local scour. Recent research indicates that introducing roughness elements on the surface of the bridge abutments can influence the flow pattern around the abutment, reducing the intensity of eddies and diverting

Scour depth beneath a pipeline undergoing forced vibration

Theoretical and Applied Mechanics Letters, 2015
AbstractThis paper studies the coupling effect of the pipeline vibration on the seabed scour. A vertical two-dimensional model is applied to numerically investigate the local scour below a vibrating pipeline with different amplitudes and periods.

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Effect of Porosity on Local Scour Around Circular Array of Cylinders in Steady Currents

Shanghai Jiaotong Daxue xuebao, 2022
The local scour around a circular array of cylindrical piles through physical model was studied under the live-bed condition, concerning the effect of porosity of the structure on the local scour development.

Observations of River Topography and Flow Around Bridges [PDF]

, 2009
This investigation was motivated by the amount of river, estuarine, and coastal infrastructure that is susceptible to extreme wave and flooding events. The high velocities and resulting shear stresses associated with high flow velocities are capable of ...
