Mechanical, rheological, and durability performances of GGBS‐based concrete for potential application to prestressed structures

Structural Concrete, EarlyView.
Abstract Ground granulated blast‐furnace slag (GGBS) is a widely used clinker substitute in concrete, recognized for its potential to significantly reduce environmental impacts. However, its application in prestressed concrete remains limited in several countries, mainly due to concerns regarding early‐age mechanical performance and long‐term ...

Effective axial strength of laterally strengthened RC pier heads with post‐tensioning method

Structural Concrete, EarlyView.
Abstract This study investigates the structural performance enhancement of reinforced concrete (RC) pier heads laterally strengthened with unbonded post‐tensioning (PT) to accommodate increased design loads following a deck replacement of an existing railway bridge.

Concrete with a very high number of load cycles—Identification of stress levels for efficient investigation of fatigue behavior

Structural Concrete, EarlyView.
Abstract Fatigue stresses are receiving increasing attention in structural engineering, particularly in the design of increasingly slender structures. However, the mechanical response of concrete—particularly its fatigue behavior under very high numbers of load cycles—is still scarcely understood.

Digital Engineering Transformation as a Sociotechnical Challenge: Categorization of Barriers and Their Mapping to DoD's Policy Goals

Systems Engineering, EarlyView.
ABSTRACT Digital Engineering (DE) transformation represents a paradigm shift in systems engineering (SE), aiming to integrate heterogeneous analytical models and digital artifacts into an authoritative source of truth to improve traceability and lifecycle management.

Printing to Fight Antimicrobial Resistance Through Nano/Microstructured Platforms

The Chemical Record, EarlyView.
Additive manufacturing enables the rational design of structured antimicrobial platforms across multiple length scales, from nanofibrous scaffolds and droplet microreactors to 3D and 4D printed constructs. By engineering confinement, interfacial chemistry, and stimuli‐responsive release, these systems exert localized action through complementary ...

Modern View of Creep of Concrete

Engineering Transactions, 1967
Tematem pracy jest analiza wpływu na pełzanie betonu różnych czynników, związanych z warunkami zewnętrznymi, obciążeniem i składem betonu. Autor przeanalizował kolejno te czynniki, zwracając uwagę na ich wzajemna zależność oraz uwzględniając również takie, które rzadko uwzględniane są w związku z pełzaniem betonu, np. temperatura otoczenia.

Tensions in Fostering Student Epistemic Agency Through Sensemaking in Elementary Science

Journal of Research in Science Teaching, EarlyView.
ABSTRACT Recent reforms in science education emphasize engaging students in authentic sensemaking practices. Central to this vision is positioning students as epistemic agents who generate questions, negotiate ideas, and co‐construct scientific understanding. Yet, classroom realities reveal persistent tensions in implementing these ideals, particularly

Differences in mammal community response to highway construction across different levels of human land use

Wildlife Biology, EarlyView.
Worldwide, transportation agencies have been involved in road mitigation efforts to reduce road mortality and promote connectivity of endangered species. Baseline data on how mammals respond to highway construction, however, are rarely collected in road mitigation and monitoring studies, including in the USA.
