Effect of Sintering Aid Composition and Porosity on the Oxyacetylene Torch Response of Silicon Nitride for RF Windows

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
Silicon nitride samples were slip cast using yttrium oxide–aluminum oxide and ytterbium oxide sintering aids to fabricate plates with up to 40% porosity and compare them to a fully dense commercial standard. Silicon nitride plates were tested with an oxyacetylene torch to investigate changes in front and back face temperature, spectral emissivity ...

Patient Involvement as Understood by Healthcare Professionals: A Multi‐Methods Study in a Danish University Hospital

Scandinavian Journal of Caring Sciences, Volume 40, Issue 2, June 2026.
ABSTRACT Aim Although patient involvement is widely promoted in healthcare policy, there is limited understanding of how healthcare professionals interpret and implement it in practice. This study explores healthcare professionals' perceptions of patient involvement and how their understanding influences interactions with patients, addressing a gap in ...

Can ERA5 Be Used to Study Mesoscale Convective System Climatological Characteristics?

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 10, 28 May 2026.
Abstract Mesoscale convective systems (MCSs) produce more than half of tropical rainfall and are central to the global hydrologic cycle. As the climate warms, environments favorable for MCSs may become more common; however, limited observational records hamper understanding of how MCSs respond to variations and changes in their environments.
