A Comparative Study of Directed Energy Deposition‐Arc and Casting: Enhancing Mechanical and Thermal Properties of Hot‐Work Tool Steels

steel research international, EarlyView.
The study investigates the influence of DED‐Arc/M versus casting on the microstructure and material properties of X40CrMoV5‐1 (AISI H13) hot‐work tool steel. DED‐Arc/M yields finer microstructures, superior mechanical strength, and ductility, but slightly reduced thermal conductivity.

Bath Vibration During Open Eye Formation in a Physical Model of a Steelmaking Ladle

steel research international, EarlyView.
Using a physical model, this study shows that vibration measurements reliably predict open eye size in steelmaking ladles, offering a practical alternative to visual monitoring. Vessel vibrations stabilize faster than the open eye, except at high frequencies near the bottom.

Madrasa Ideologies of English in Bangladesh: Questioning ELT‐Aid and Post‐9/11 De‐Islamization

TESOL Quarterly, EarlyView.
Abstract External donors increasingly promote English as a notionally value‐neutral language of socioeconomic advancements in the Muslim South, overlooking local ideological diversities. Furthermore, national and Western forces deploy English as a tool to de‐Islamize madrasas (Islamic educational institutes) in the post‐9/11 world for global peace ...

Wildfire Ash Alters Freshwater Crustacean Behavior: Disentangling the Contributions of Suspended Macroparticles and Ash‐Induced Alkalinization

Environmental Toxicology, EarlyView.
ABSTRACT Climate change and anthropogenic ignitions are intensifying wildfire frequency worldwide, elevating the risk of freshwater contamination by ash. In water, dissolved ash releases ions and other toxic constituents that increase pH and alter physicochemical conditions, while suspended ash particles may impose mechanical stress, disrupt behavior ...

Extensive Subcutaneous Emphysema and Pneumomediastinum Following Eustachian Tube Dilation and PET Insertion: A Rare Complication

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Introduction Eustachian tube dilation (ETD) is an increasingly popular and seemingly safe method of treating ETD. We present a rare case of subcutaneous emphysema and pneumomediastinum following ETD. Methods Retrospective chart review. Patient consent was obtained for data collection, analysis, drafting, and publication of information ...
