Hydrogen-based reduction of iron ores is the key technology for future sustainable ironmaking, to mitigate the CO2 burden from the steel industry, accounting for ~7–8% of all global emissions. However, using hydrogen as a reductant prompts concerns about hydrogen embrittlement in steel products....
In the middle of the night, they sailed back to Troy and marched quietly to the gates, which had been thrown open by the soldiers hidden in the horse. The rest is blood and guts and a lot of drunken mayhem. Today, some scientists question the validity of the story. They argue, for ...
When the analyses were performed according to the Nutri-Score and the SAIN,LIM classes (Fig. 3), NOVA4maj marketed foods were distributed in all classes of nutrient profiles, including the healthier ones (e.g., 26% and 35% of NOVA4maj foods were in class A of the Nutri-Score and in...
As a vital piece of emerging technology, it is like the epitome of the cool tech we often see in the stunning homes of famous science fiction and superhero movies that is enough to make Elon Musk envious. Thanks to IoT devices, Iron Man’s Tony Stark can give commands to his home ...
the engines - four marinegas turbinesthat Rolls-Royce describes as the most powerful gas turbines available today - will power generators that produce a total of 80 megawatts of electricity. That electrical power will then be distributed to most of the ship's systems and the electric motors that...
A large body of epidemiological evidence demonstrates that exposure to particulate matter (PM) is associated with increased morbidity and mortality. Many epidemiology studies have investigated the health effects of PM in Europe and North America and focussed on traffic derived PM. However, elevated leve...
A supply chain includes all the raw materials and parts that are made into a product and distributed up the chain for manufacture and sale. In contrast, avalue chainencompasses all the individual steps that are taken to create a marketable product. That includes not only physical components but...
"Right now, certain companies control the way everyone thinks and what information is distributed to whom and how information is prioritized," says Hough, 21. In a generative AI world, "consumers can come to their social media networks or their search engines and be like, this is how I thi...
in the bowling alley is suffering. But if that woman is immune, then the disease stops with her, because the virus has nowhere else to go (assuming that the guy in our example didn't have contact with anyone else). By her immunity, she protected all the people on subsequent lanes, ...
In this set-up a thin metal foil is placed on the back of a non-conducting projectile. When power flows through this foil it vaporizes and becomes a plasma, which carries the current. Here's how the pieces work together: An electric current runs from the positive terminal of the power ...
