Health Promotion Journal of Australia, Volume 36, Issue 4, October 2025.ABSTRACT Issue Addressed Health inequity for sexual minority (lesbian, gay and bisexual) people compared with heterosexual people is well documented globally. However, limited local data have been used to inform health policy and practice. This project analysed data from the New Zealand Health Survey to determine areas of inequity in health behaviours ...

Exogenous and Endogenous Displacements in 3D Porous Media
Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.Abstract Gas displacement is ubiquitous in engineering applications and natural phenomena. Compared to exogenous displacement, studies on endogenous displacement within 3D porous media remain scarce. This study investigates gas invasion and gas exsolution by depressurizing CO2‐saturated solution in specimens with distinct wettability.
