Effect of Postweld Heat Treatment on Laser‐Welded Duplex Stainless Steel: Crystallographic Patterns and Fatigue Behavior

open access: yessteel research international, EarlyView.
Laser welding of duplex stainless steel disrupts phase balance, promotes nitride precipitation, and reduces fatigue resistance. Postweld heat treatment restores austenite and dissolves nitrides, but the resulting crystallography and phase morphology still impair fatigue performance.

General formulation for uniform and non‐uniform high‐strength steel slender I‐section beams

open access: yesSteel Construction, EarlyView.
Abstract The Ayrton–Perry approach is the basis of Eurocode 3 rules for buckling resistance, with distinct curves and imperfection factors depending on section type, steel grade, and other parameters. For generic members – built‐up or not, uniform or not, with complex supports or not – the code allows either the general method (clause 8.3.4 of Eurocode

Antimicrobial Residues in a Key Cerrado River: Distribution, Persistence, and Effects on Zebrafish Embryo‐Larval Development

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The current study aimed to quantify the antimicrobials amoxicillin (AMX), cefazolin (CFZ), chloramphenicol (CHL), metronidazole (MTZ), and sulfamethoxazole (SX) in effluents and surface water of an important Cerrado river, calculate their half‐lives, and analyze their ecotoxicity following single and combined exposures.

Environmentally Realistic Metal Mixture Concentration Impacts Early Development in Zebrafish Larvae

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The dispersion of metals in the environment leads to the presence of metal mixtures in impacted ecosystems, but few studies have addressed their impact on early developmental processes in fish. Here, we investigated the effect of metal mixtures reported in the Doce River basin in Brazil, including Fe, Mn, and Cd, either singly or as a mixture ...

Enterococcus faecalis and Endodontic Treatment Failure: A Qualitative Systematic Review of Its Role and Elimination Strategies

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT The aim of this study was to synthesize evidence on the influence of Enterococcus faecalis on endodontic treatment failure and strategies for its elimination. This study followed the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines and was registered in PROSPERO (CRD420251022741).
