Recovery of Cs-137 from electric arc furnace dust by lixiviation
Case Studies in Chemical and Environmental Engineering, 2022 An orphan radioactive source of Cs-137 was inadvertently melted in an electric arc furnace, generating large volumes of electric arc furnace dusts contaminated with Cs-137 (137Cs-EAFD). This work proposes the Cs-137 recovery from 137Cs-EAFD by applying a

Applied Vegetation Science, Volume 26, Issue 2, April/June 2023., 2023 We studied the effect of livestock type (sheep, cattle) and grazing intensity on sand grassland vegetation. The effect of grazing intensity was much higher in the studied grasslands than that of livestock type, which is in contrast with results for saline grasslands.

Journal of Flood Risk Management, Volume 15, Issue 3, September 2022., 2022 Abstract Many urban areas at higher flood risk owing to climate change, and mitigating these risks requires a combination of structural and nonstructural adaptation measures. Previous studies assessing adaptation measures are limited in quantifying the effects of climatic and social changes.

Fuzzy‐based frequency security evaluation of wind‐integrated power systems
IET Energy Systems Integration, Volume 3, Issue 4, Page 451-463, December 2021., 2021 Abstract The transition to renewable energy‐based power systems is fast progressing. One of the main challenges in keeping a power system with high operational reliability is to maintain the system frequency. As synchronous generator units are being replaced with power‐electronic converters, the rotating mass and the system inertia are decreasing ...

Frequency security constrained control of power electronic‐based generation systems
IET Renewable Power Generation, Volume 15, Issue 10, Page 2246-2256, 27 July 2021., 2021 Abstract Power grids with high integration of power electronic converters face new issues that have not existed before. The frequency in the power system is highly related to the inertia and the rotational speed of the operational synchronous machines.

Determination of ZnO Amount in Electric Arc Furnace Dust and Temperature Dependence of Leaching in Ammonium Carbonate by Using of X-Ray Diffraction [PDF]
Archives of Metallurgy and Materials, 2018 Zinc is present in electric arc furnace dust (EAFD) mainly in two basic minerals, namely as franklinite ZnFe2O4 and/or zincite ZnO. While zincite is relatively reactive and easily treatable, franklinite is considerably refractory, which causes problems ...

IRON ORE SINTER PRODUCTION USING ELECTRIC ARC FURNACE DUST AS RAW MATERIAL [PDF]
Tecnologia em Metalurgia, Materiais e Mineração, 2013 The steel production through Electric Arc Furnaces (EAF) generates approximately 15% to 20% of Electric Arc Furnace Dust (EAFD). This waste is considered dangerous due to the presence of metals as lead and cadmium that leach in contact with water ...
