Feasibility of Red Mud Recycling via Hydrogen Plasma Smelting Reduction: Insights From Large‐Scale Laboratory Experiments

open access: yessteel research international, EarlyView.
Red mud processing in a laboratory hydrogen plasma facility, exceeding one hundred grams of input material, to evaluate the first scale‐up steps for iron recovery. This study demonstrates the feasibility of red mud reduction and the removal of harmful elements.

Experimental and Computational Investigation of Slag–Refractory Interactions Under Conditions Relevant to Hydrogen Plasma Smelting Reduction

open access: yessteel research international, EarlyView.
This study investigates how slag interacts with magnesia–carbon (MgO–C) refractories under conditions relevant to hydrogen plasma smelting reduction. High‐temperature refractory wear tests are combined with thermodynamic modeling to examine refractory dissolution into slag and slag infiltration into the refractory.

Evaluation and Interpretation of Genetic Effective Population Size of Delta Smelt from 2011–2014

open access: yesSan Francisco Estuary and Watershed Science, 2017
https://doi.org/10.15447/sfews.2017v15iss2art5Delta Smelt have collapsed demographically, but little is known about their current genetic status. We used 12 microsatellite loci to evaluate two measures of the effective population size (Ne) of Delta ...

Assessing the Health Impacts of Contaminants on Green Turtles (Chelonia mydas) Along the Southern Coast of Brazil

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Chemical pollutants pose a significant threat to marine ecosystems. Among these contaminants are trace elements and polycyclic aromatic hydrocarbons (PAH). Green turtles can be employed to evaluate the oceans' health due to their coastal habitats and exposure to multiple threats.

Environmentally Realistic Metal Mixture Concentration Impacts Early Development in Zebrafish Larvae

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The dispersion of metals in the environment leads to the presence of metal mixtures in impacted ecosystems, but few studies have addressed their impact on early developmental processes in fish. Here, we investigated the effect of metal mixtures reported in the Doce River basin in Brazil, including Fe, Mn, and Cd, either singly or as a mixture ...

Analysing policy success and failure in Australia: Pink batts and set‐top boxes

open access: yesAustralian Journal of Public Administration, EarlyView.
Abstract This article examines two Australian government programs from the Rudd/Gillard Labor government, the Home Insulation Program (HIP) and the Digital Switchover Household Assistance Scheme (HAS). Both became shibboleths of the Labor government's perceived waste and incompetence.

The effects of scientific uncertainty and values trade‐offs on flow management decisions for an endangered fish

open access: yesEcosphere
Consumptive use of freshwater is of concern in many estuarine ecosystems, and various frameworks have been used to prescribe environmental flows to benefit native species.
