ISIJ International, Vol. gravity. Porosity 11 wasdetermined by vacuumpack- ing the sinter specimenwith a water-impermeablefilm, weighing the specimenin water, measuringthe apparent specific gravity of the specimen, and calculating the porosity of the specimenfrom the measuredtrue specific gravity. The shrinkage of the sinter cake was continuously measuredIn …

Since 1989, China has become the world's largest aquaculture producer through pond culture, significantly contributing to global food security but potentially posing environmental threats. However, little is known about the changes in the pond water quality at broad spatial and temporal scales, thus creating challenges in the sustainability of pond aquaculture. Herein, we …
