Laboratory Flume Experiments on the Formation of Spanwise Large Wood Accumulations: Part II—Effect on local scour

Water Resources Research, 2019
In this second companion paper, hydraulic model tests were conducted to analyze local scour due to natural spanwise large wood (LW) accumulations. Spanwise accumulations were modeled using a vertical barrier, similar to a LW retention rack in prototype ...

Mechanics‐based model for cold joints in reinforced concrete members

Structural Concrete, EarlyView.
Abstract This study introduces a mechanics‐based numerical model to characterize the behavior of cold joints in reinforced concrete members subjected to monotonic loading. The model incorporates mechanisms such as interface slip and opening, aggregate interlock, clamping force, and dowel action of the reinforcing bars crossing the interface.

Scour Depth Around Cylinders Under Combined Effects of River Flow and Tidal Currents

Journal of Marine Science and Engineering
The safety of coastal structures is a growing global concern due to the combined effects of strong tides and river flow. In this study, the local scour around cylinders under the influence of tides combined with river flows was investigated numerically ...

Within-Event Spatially Distributed Bedload: Linking Fluvial Sediment Transport to Morphological Change [PDF]

, 2012
Maps of apparent bedload velocity are presented along with maps of associated channel change. Apparent bedload velocity is the bias in acoustic Doppler current profiler (aDcp) bottom track (Doppler sonar) due to near-bed particle motion (Rennie et al ...

A structured, behavioural science approach to the preparation of antimicrobial stewardship interventions for companion animal veterinarians

Veterinary Record, EarlyView.
Abstract Background A structured, behavioural science approach was adopted to develop antimicrobial stewardship interventions in UK first‐opinion companion animal veterinary practice. The objectives were to identify behavioural targets for intervention and to understand how practice contexts influence these behaviours.

Subaqueous “yardangs”: analogs for aeolian yardang evolution

, 2013
Landforms, morphologically similar to aeolian yardangs but formed by erosion of bedrock by currents on an estuarine rock platform, are described for the first time. The geometries of the “yardangs” are described and related to semi-lemniscate shapes that

‘Knowledge, attitudes and practices’ survey of Austrian veterinarians' antibiotic use in clinical practice

Veterinary Record, EarlyView.
Abstract Background Antimicrobial resistance (AMR) is a critical global health issue, with antimicrobial use (AMU) in veterinary medicine playing a relevant role in its emergence. This study aimed to evaluate the knowledge, attitudes and practices of Austrian veterinarians regarding AMU and AMR.

“For three of my four miscarriages I was at work…” Experiences of miscarriage, infertility and assisted fertility in veterinary workplaces

Veterinary Record, EarlyView.
Abstract Background Miscarriage, infertility and assisted fertility (MIAF) can profoundly impact physical and mental health. The aims of this study were to investigate how veterinary professionals’ work environments and employers impacted their experiences of MIAF and to identify how workplace experiences of MIAF could be improved.

Reusing health records from farm animal practices at scale: A potential complementary method of surveillance

Veterinary Record, EarlyView.
Abstract Background Disease in primary care frequently represents a surveillance blind spot, particularly for diseases affecting farm animals. Methods Electronic health records (EHRs) were collected from four farm animal veterinary practices in Wales (February 2024‒January 2025) as part of a pilot study.
