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 ...

Study on the Mechanism of Local Scour Around Bridge Piers

Journal of Marine Science and Engineering
Local scour around bridge piers poses significant challenges to the stability and safety of bridge structures. Local scour results from the combined effects of increased longitudinal flow velocity, the direct impact of the flow in front of the pier, and ...

Theoretical georeferenced potential for biomethane production in Brazil from organic waste, including logistics and cost aspects

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract One of the challenges for biomethane production in Brazil, as well as its use, is related to transportation logistics, owing to the lack of detailed studies of the entire supply chain at a national level, which includes all the stages from waste collection to transportation for its final use.

Studying the effect of partial blockage on multi-vents bridge pier scour experimentally and numerically

Ain Shams Engineering Journal, 2018
The local scour depth at bridge supports due to partial blockage on front of multi-vents bridge pier is studied experimentally and numerically. The existence of blockage such as debris and industrial wastes, leads to increase the local scour depth around

Experimental Study on Local Scour at the Monopile Foundation of an Offshore Wind Turbine under the Combined Action of Wave–Current–Vibration

Journal of Marine Science and Engineering
Monopile foundations are the most widely used offshore wind turbine foundations. The experiments were conducted to investigate the influencing factors of local scour around the monopile under the action of wave–current–vibration.

Deformation Analysis of Large Diameter Monopiles of Offshore Wind Turbines under Scour

Applied Sciences, 2020
The displacement of monopile supporting offshore wind turbines needs to be strictly controlled, and the influence of local scour can not be ignored. Using p–y curves to simulate the pile–soil interaction and the finite difference method to calculate ...

A Green Consumer‐Based Approach to Advance Branding Strategies in Experiential Consumption Contexts. Insight From the Cruise Industry

Business Strategy and the Environment, EarlyView.
ABSTRACT Growing environmental awareness has intensified demand for sustainability and transparency, especially in cruise tourism, a high‐impact and highly scrutinised service context. This study examines how green consumption values (GCV) shape passengers' perceptions of the credibility of green marketing claims (believability) and, in turn, influence
