Schmidt hammer exposure dating for brick masonry

Geochronometria, 2020
This research investigates the validity of the Schmidt hammer exposure dating (SHED) technique as a complementary means to date monuments according to the evaluation of the brick decay from masonry exposed to climatic conditions. The degree of surface weathering, I₅ (%) is calculated as an indicator of the ageing effect and ...

Phase Transformation Behavior of Continuously Cooled Fe–C–V–(Mo) Alloys

steel research international, EarlyView.
Additions of vanadium and molybdenum microalloying are shown to reshape phase transformations in clean low‐carbon steels. By tracking microstructural shifts during continuous cooling, the work uncovers the correlation between transformation kinetics, ferrite morphology, and hardness.

Experimental analysis on partial replacement of cement with brick powder in concrete

Case Studies in Construction Materials, 2021
The aim of this research is to interrogate the feasibility of using Waste brick powder (WBP) successfully in concrete as a substitute of cement. The replacement levels were kept at 5% and 10%, compared to the reference concrete.

Vision language models for bridge inspections: A review of applications in image‐based damage documentation

Structural Concrete, EarlyView.
Abstract Automating bridge inspections requires more than detecting individual damage instances. It demands systems capable of describing, contextualizing, and interpreting damage in an inspection‐relevant manner. Conventional computer vision approaches, such as object detection and segmentation, primarily address visual recognition tasks and are ...

Secularism, Gender and Masculinity in Nineteenth‐Century Cremation in Europe and the USA

Gender &History, EarlyView.
ABSTRACT This essay explores, from transnational perspectives, the early history of modern cremation, which developed in the long nineteenth century with secularist connotations. I argue that the beginnings of modern cremation were shaped by bourgeois men who claimed certain identifiers for themselves in a gendering and Othering way.
