Restoring Balance: The Intersection of Management and Fishing Sustainability in Indonesia
Fisheries Management and Ecology, Volume 33, Issue 1, Page 54-68, February 2026.ABSTRACT As the world's second‐largest fish producer, Indonesia plays a crucial role in global fishing. However, overfishing, habitat degradation, population growth, and container port traffic threaten the sustainability of the fishing industry. We examined the impacts of fishing, population growth, and container port traffic on Indonesia's fishing ...

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 2, February 2026.ABSTRACT Elite performance in Olympic winter sports depends on the interplay among the athlete, equipment, and the snow or ice. This naturally evolves with temperature, humidity, wind, preparation, and contact between the equipment and its surface. Together, these factors continuously rebalance the forces of gravity, aerodynamic drag, and friction ...
