Smelting Reduction of HIsarna Slag with Methane
steel research internationalTo study the smelting reduction behavior of methane in the HIsarna process, the isothermal reduction experiments of HIsarna slag with 6 wt% of FeO were conducted at the temperatures of 1450, 1475, and 1550 °C, using 5 vol% CH4‐Ar. The effect of the gas injection flow rate on the overall reduction rate was investigated in the range of 0.5–1.5 L min−1 ...

The Fish Behind Fish Feed: Rethinking Transparency Using DNA Tools
Fish and Fisheries, EarlyView.ABSTRACT Aquaculture is now the fastest growing food sector and may be a promising solution to increasing seafood demands. Yet, carnivorous aquaculture species such as salmon and seabass continue to rely on fishmeal and fish oil (FMFO), which are derived largely from pelagic fish that are sometimes key to the food security of some coastal nations. This

Fisheries Management and Ecology, EarlyView.ABSTRACT Shore‐based observers are increasingly being used in place of at‐sea observers to monitor and sample commercial fisheries catch. However, few evaluations assess whether these programs meet their stated goals or how to optimize them, and industry data are rarely tested for accuracy despite serving as the foundation for catch accounting. Using a
