Numerical Modeling of Vegetation Influence on Tsunami-Induced Scour Mechanisms

Journal of Marine Science and Engineering
Tsunami-induced scour around coastal embankments and nearshore structures is a primary cause of structural instability and failure. However, the hydrodynamic mechanisms by which coastal vegetation mitigates this scour remain insufficiently understood ...

Local scour at complex bridge piers [PDF]

, 2014
The prediction of scour depths at bridge piers is a necessary input to the design of the pier foundations. Local scour around bridge foundations is one of the most significant causes of bridge failures.

Scour effects on p-y curves for shallowly embedded piles in sand

, 2016
Soil scour around a shallowly embedded pile can significantly compromise its lateral response, reducing both stiffness and capacity. Estimation of the lateral pile response must take into account both the scour-hole geometry and the overconsolidation ...

Perfluorohexanone for Clean Fire Suppression: Mechanisms, System Design, Applications, and Future Directions

Safety Science and Technology, EarlyView.
Driven by halon and high GWP agent phase out, perfluorohexanone is increasingly deployed in enclosures such as data centers, marine machinery spaces, and industrial process lines. This review summarizes application performance, discharge and distribution design, material compatibility, and byproduct control and maps practical gaps for large volume and ...

SCOUR NEAR SPILL-THROUGH TYPE ABUTMENT ON CLEAR-WATER SCOUR CONDITION FOR MULTI-SECTION CHANNELS

Journal of Civil Engineering
Scour is a natural phenomenon caused by erosion due to water flow on the alluvial channel bed and channel wall. In fact, scour happened in the bridge abutment is total scour, that is a combination between local scour, general scour, and constriction ...

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.

Temporal variation of local scour at bridge piers with complex geometries

, 2012
Scour at uniform cylindrical piers founded in cohesionless sediments has received much attention over the last decades and there are extensive laboratory data for these conditions in literature.

‘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.
