Char Layer Thickness Evolution During Structural Timber Fire Experiment and Final Density Profile
Fire and Materials, EarlyView.ABSTRACT This paper evaluates several non‐destructive experimental methods for determining the char layer thickness and its density profile in structural timber samples exposed to standard ISO 834 fire curve experiments. Microwave echo pulse, ultrasonic echo pulse, X‐ray computed tomography, and resistance drilling were evaluated.

Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review
Heat Transfer, EarlyView.ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that

Knowledge and Process Management, EarlyView.ABSTRACT This study examines the extent to which intellectual capital (IC) supports firms' value generation and financial resilience, and how these effects are conditioned by profitability. IC is quantified using the “modified value‐added intellectual coefficient (MVAIC)” for a panel of 103 manufacturing firms listed on the Pakistan Stock Exchange over
