Retrospective Evaluation of Novel Synthetic Opioids and Xylazine Chronic Intake by Post‐Mortem Hair Testing

open access: yesDrug Testing and Analysis, EarlyView.
The study presents a validated UPLC‐MS/MS method applied for the detection of fentanyl, NPFs, xylazine, nitazenes in hair samples from 250 post‐mortem cases collected at the Jefferson County Coroner/Medical Examiner's Office (Birmingham, AL, USA). In 52% of the analyzed hair samples, fentanyl, its main metabolites, and related analogs were detected ...

Temperature‐dependent shear behavior and constitutive model of the rock–concrete interface

open access: yesDeep Underground Science and Engineering, EarlyView.
Shear tests were conducted to investigate the temperature‐dependent shear behavior of the rock–concrete interface, highlighting the interaction between the surrounding rock and the lining during tunnel fires. Under experimental conditions, concrete exhibited greater temperature sensitivity than rock, with the shear fracture surface transitioning from ...

Experimental study on burning rate and flame geometry in construction tunnel fires under high geothermal conditions

open access: yesDeep Underground Science and Engineering, EarlyView.
Abstract As tunnel construction advances in lengths and depths, the construction of tunnels in high geothermal environments has become increasingly common, raising significant fire risks. In this study, a 1:20 scale model tunnel test platform was constructed to investigate the effects of a high geothermal environment on fire behavior in tunnels during ...
