Effects of B‐Site Nb Substitution on ORR Activity in Perovskite Cathode Materials for Solid Oxide Fuel Cells

SusMat, EarlyView.
B‐site Nb substitution in PSCF perovskite cathodes modulates oxygen vacancy formation and electronic structure, thereby tailoring oxygen adsorption and ion transport properties. A moderate Nb level (5–10%) optimizes the balance between surface activity and conductivity, enhancing ORR kinetics and SOFC performance. ABSTRACT Solid oxide fuel cells (SOFCs)

Estimation of Local Scour Dimension below Siphon Spillway with the Ski-jump Bucket Energy Dissipater Using the Group Method of Data Handling (GMDH)

علوم آب و خاک, 2018
The investigation of local scour below hydraulic structures is so complex that makes it difficult to establish a general model to provide an accurate estimation for the local scour dimension.

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.

‘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.

Numerical study on local scour characteristics around submarine pipelines in the Yellow River Delta silty sandy soil under waves and currents

Deep Underground Science and Engineering
Due to their high reliability and cost‐efficiency, submarine pipelines are widely used in offshore oil and gas resource engineering. Due to the interaction of waves, currents, seabed, and pipeline structures, the soil around submarine pipelines is prone ...

Investigation of Edge Scour and Undermining Process of Conical Structure Around a Monopile

Journal of Marine Science and Engineering
The scour protection performance of the conical structure under different slope angles, α, was investigated through numerical simulations. By solving the Navier–Stokes (N–S) equations, using the Renormalization Group (RNG) k–ε turbulence model and the ...

“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.

An Investigation into the Lateral Bearing Performance of a Single Pile Embedded at a Three-Dimensional Asymmetric Local Scour Site Using the Modified Strain Wedge Model

Applied Sciences
The scouring effect is widely acknowledged as a primary contributor to the weakening in the bearing performance of offshore piles; it often results in asymmetric scour patterns around the pile.
