Navigating Inequality: A Student-Led Critical Study of Black First-Generation Students’ Experiences in South Africa

SAGE Open
This study draws on Schlossberg’s transition theory to explore the experiences of first-generation students (FGSs) in South African higher education. Rather than adopting a purely deficit-based framing, we examined how FGSs experience and interpret their

Biological processes and factors involved in soft and hard tissue healing

Periodontology 2000, Volume 97, Issue 1, Page 16-42, February 2025.
Abstract Wound healing is a complex and iterative process involving myriad cellular and biologic processes that are highly regulated to allow satisfactory repair and regeneration of damaged tissues. This review is intended to be an introductory chapter in a volume focusing on the use of platelet concentrates for tissue regeneration.

Collaborative Optimization of Multiport‐Integrated Energy System Based on Hydrogen‐Powered Vessel Coupling

International Transactions on Electrical Energy Systems, Volume 2025, Issue 1, 2025.
The port‐integrated energy system (PIES) presents a transformative pathway for decarbonizing port operations through multienergy synergies. Power‐to‐hydrogen technology converts surplus renewable energy into green hydrogen, which is stored and reconverted to electricity via fuel cells during supply shortages.
