‘I think your child might be autistic’: A qualitative survey study examining how school staff broach initial interactions with parents whose children may be autistic

British Journal of Special Education, Volume 53, Issue 1, Page 41-50, March 2026.
Abstract Recognising and understanding that a child might be autistic is an important first step in the autism diagnostic pathway. For many families, this process involves working alongside school staff and, in England, this tends to be led by the Special Educational Needs Coordinator (SENCO). Existing research highlights the importance of how and when

Characterization of As-Welded Microstructure in a P91 Steel

Welding Journal
The microstructure of the heat affected zone (HAZ) and fusion zone (FZ) in the as-welded condition of a single-pass weld performed by the flux-cored arc welding (FCAW) process was studied in a P91 steel using microhardness measurements, field-emission scanning electron microscopy, transmission electron microscopy, and x-ray diffraction.

Cyclic hardening and softening of high-strength steels

Journal of Mechanical Engineering and Sciences
316L and P91 steels, commonly used for high-temperature applications in power plants, experience low-cycle fatigue. In this work, the cyclic stress-strain behaviour of 316L and P91 materials was analyzed. Experimental data from the material's hysteresis
