Toward the Application of Multiaxial Failure Criteria: Mean Stress Sensitivity of Carbide‐Rich, High‐Alloy PM‐HIP Tool Steels Under Axial and Torsional Cyclic Loading

steel research international, EarlyView.
This study quantifies axial and torsional long‐life fatigue (LLF) behavior of three carbide‐rich PM‐HIP tool steels, correlating LLF strength with intrinsic defect size and cleanliness, thereby extracting material‐specific mean stress sensitivities and Haigh diagrams.

Woven Eutectic Lamellar Structures Lead to Ultrahigh Strength and Energy Absorption Capacity in Additively Manufactured Lattice Structures

Small Structures, Volume 6, Issue 5, May 2025.
Herein, AlCoCrFeNi2.1 is selected to produce lattice structures by selective laser melting. The as‐printed lattice structures consist of numerous colonies of nanosized eutectic lamellar structures which are bent and interwind with each other to form a woven microstructure. The unique microstructure leads to unprecedented effective metal strength, yield

Critical Multilingual Language Awareness, Antiracism, and Raciolinguicized Subjectivities in Teacher Education

TESOL Quarterly, EarlyView.
Abstract Race and language collaborate in structuring educational inequities, creating urgency for teacher education to equip all teachers to equitably serve racialized multilinguals as antiracist language educators. Emphasizing the inseparability of racial and linguistic justice, this article examines teacher candidates' (TCs') learning journeys ...

Standardised Innovation Management Systems: Modelling the Antecedents of Certification and Maintenance Benefits

Creativity and Innovation Management, EarlyView.
ABSTRACT The literature lacks a comprehensive model examining the performance impact of certifying and maintaining standardised innovation management systems (SIMS) or clarifying the advantages of standardisation. This study addresses that gap by analysing the key determinants of the benefits associated with SIMS certification and maintenance.

Noise Exposure in a Dental Teaching Hospital: Investigations and Recommendations for Dental Personnel

European Journal of Dental Education, EarlyView.
ABSTRACT Introduction Exposure to excessive noise is a highly preventable occupational risk, with irreversible side effects that may negatively impact an individual's quality of life, such as noise‐induced hearing loss and tinnitus. Dental personnel may be at particular risk due to their exposure to high levels of noise from dental equipment.

Knowledge, Attitudes, and Perceptions of Evidence‐Based Dentistry Among Final‐Year Dental Students: A Multinational Study Across 6 Countries and 8 Universities

European Journal of Dental Education, EarlyView.
ABSTRACT Introduction Evidence‐based dentistry (EBD) refers to the use of the best available evidence in combination with clinical expertise and patient values to guide clinical decision‐making. Whilst evidence‐based medicine (EBM) is widely adopted in medicine, EBD is much less frequently used in dentistry. Research into dental students' views towards
