Dyad pedagogy in practical anatomy: A description of the implementation and student perceptions of an adaptive approach to cadaveric teaching

open access: yesAnatomical Sciences Education, Volume 16, Issue 1, Page 99-115, January/February 2023., 2023
Abstract Prior to the challenges imposed by the Covid‐19 pandemic, anatomy practical sessions at Trinity College Dublin involved eight to 10 students per donor station, rotating between digital learning, anatomical models/osteology, and dissection activities for three hours weekly.

When Fire Attacks: How does Concrete Stand up to Heat ? [PDF]

open access: yesarXiv
Fire is a process that generates both light and heat, posing a significant threat to life and infrastructure. Buildings and structures are neither inherently susceptible to fire nor completely fire-resistant; their vulnerability largely depends on the specific causes of the fire, which can stem from natural events or human-induced hazards.

Competitive Anion Anchoring and Hydrogen Bonding in Multiscale‐Coupling Composite Quasi‐Solid Electrolytes for Fire‐Safety and Long‐Life Lithium Metal Batteries

open access: yesAdvanced Science, EarlyView.
A novel self‐assembly fiber (SAF)/polymers/LATP composite quasi‐solid electrolytes based on TFSI‐ anchoring and intermolecular hydrogen bonding competitive and multiscale coupling effects, named SL‐CQSE, which possesses the perfect reconciliation of facilitating Li+ migration, inducing stable SEI layer construction, and strengthening mechanical ...

Unlocking Modulation Rule of Heterointerface Engineering Induced D‐Band Center on Polysulfides Conversion in Lithium–Sulfur Batteries

open access: yesAdvanced Science, EarlyView.
The homologous heterostructure of ZIF‐67‐derived CoSe2@CoSe0.25S1.75 with a behavior of semi‐coherent phase boundary is constructed to modulate the d‐band center (εd) of Co, which can be a significant descriptor for Li+ storage of S cathode. It is revealed that the adsorption and conversion ability to LiPSs and the discharge‐specific capacity describe ...

The effects of extreme weather on rural transportation infrastructure and crop prices along the Lower Mississippi River

open access: yesApplied Economic Perspectives and Policy, EarlyView.
Abstract Extreme weather events are worsening the fragile rural infrastructure in the United States, impacting trade flows of agricultural products. The Mississippi River, vital for transporting agricultural commodities, reached historic lows during the 2022 and 2023 fall harvests, increasing transportation costs and lowering crop prices.

Design of monolithic concrete foundation slabs with FRP reinforcement

open access: yesVestnik MGSU
Introduction. Over the past decade, the share of concrete structures reinforced with composite polymer reinforcement (FRP) has increased, which is due, among other things, to the development of the regulatory and technical framework in this direction ...
