Green steel from red mud through climate-neutral hydrogen plasma reduction.

Red mud is the waste of bauxite refinement into alumina, the feedstock for aluminium production. With about 180 million tonnes produced per year, red mud has amassed to one of the largest environmentally hazardous waste products, with the staggering amount of 4 billion tonnes accumulated on a global scale. Here we present how this red mud can be turned into valuable and sustainable feedstock for ironmaking using fossil-free hydrogen-plasma-based reduction, thus mitigating a part of the steel-related carbon dioxide emissions by making it available for the production of several hundred million tonnes of green steel.

A Complicated Case of Aspirin-Exacerbated Respiratory Disease With Kounis Syndrome.

Kounis syndrome is angina or acute coronary syndrome caused by mast cell degranulation and inflammatory cell activation. We present a case of a patient with underlying aspirin-exacerbated respiratory disease (AERD) and previous anaphylaxis to aspirin. The patient underwent aspirin desensitization and was then treated with high-dose aspirin.

Fundamentals of Green Steel Production: On the Role of Gas Pressure During Hydrogen Reduction of Iron Ores.

Unlabelled: Out of the multitude of researched processing routes for sustainable ironmaking, hydrogen-based direct reduction and hydrogen plasma smelting reduction (HyPSR) are currently the most promising candidates for a successful industrial application. Both processes operate under gaseous atmospheres, which turn the partial and absolute pressure of hydrogen into a relevant process parameter. Here, we present first insights into the influence of total pressure and concentration of hydrogen on the reduction of hematite, focusing on the more pressure-sensitive route (HyPSR).

International and Interprofessional Collaboration: An Innovative Week of Learning Across Three Professions, Three Universities, and One Ocean.

As the COVID-19 pandemic prevented planned international travel opportunities for students and faculty, faculty at three universities from three professions created a four-day innovative, online learning experience. Each session included presentations from each country, small-group discussions, and evaluation. The topics appealed to students regardless of profession or nationality.

Characterization of Antimicrobial Resistance Genes and Virulence Factors in the Genomes of ST69 Isolates from Preweaned Dairy Calves and Their Phylogenetic Relationship with Poultry and Human Clinical Strains.

sequence type 69 (ST69) are common causative agents of extraintestinal infections occurring in the bloodstream, cerebrospinal fluid, surgical sites, and, most frequently, the urinary tract. The objective of this study was to analyze the genomic characteristics of 45 antimicrobial-resistant ST69 strains that were isolated from 28 calves on eight dairy farms in Pennsylvania, USA. The genomes were sequenced and the antimicrobial resistance genes (ARGs), virulence factors (VFs), and plasmid replicons were identified .
