A Multi‐Analytical Approach for the Compositional Characterization and Chronological Discrimination of Benin (Nigeria) Metal Sculptures

open access: yesArchaeometry, Volume 68, Issue 5, Page 1022-1036, October 2026.
ABSTRACT This study presents a multi‐analytical archaeometric approach for the compositional characterization and chronological discrimination of Benin metal sculptures in relation to the 1897 Punitive Expedition. The methodology integrates elemental composition (XRF and ICP), stable lead isotope ratios (MC‐ICP‐MS) for alloy system characterization ...

Management of Massive Post‐Tracheostomy Subcutaneous Emphysema With an Adjustable‐Length, Wire‐Reinforced Tracheostomy Tube: A Case Report

open access: yesClinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Massive subcutaneous emphysema with pneumomediastinum is a rare but potentially life‐threatening complication following tracheostomy, for which standardized management strategies are lacking. We report the case of a 67‐year‐old man who developed progressive cervicofacial and thoracic subcutaneous emphysema on postoperative Day 9 after an ...

Investigating Nucleation Inhibition in the Dehydrogenation of Perhydro Benzyltoluene

open access: yesChemical Engineering &Technology, Volume 49, Issue 9, September 2026.
Nucleation can profoundly influence mass transport and the performance of reactive systems. Building on observations from other LOHC systems, this work demonstrates that gas bubble nucleation enhances hydrogen release during perhydro benzyltoluene dehydrogenation.

Quantifying Lateral Support of Steel Girders Directly Connected to Trapezoidal Sheeting

open access: yesce/papers, Volume 9, Issue 2-3, Page 2055-2060, September 2026.
Abstract Flexural and lateral–torsional buckling (LTB) may govern the construction stage of steel and steel–concrete composite girders, when the compression flange is not yet restrained by composite action. Trapezoidal profiled steel sheeting, used as permanent formwork and often directly fastened to the top flange, can contribute to construction‐stage

Explicit FE Modelling of Cold‐formed Steel K‐Joints using Dimpled Screwed Connections

open access: yesce/papers, Volume 9, Issue 2-3, Page 1646-1651, September 2026.
Abstract Cold‐formed steel (CFS) thin‐walled structures, such as floor joists, are becoming popular in mid‐rise buildings. These joists are typically fabricated as truss systems, with unlipped channels forming the top and bottom chords and lipped stiffened channels used as diagonal web members.
