Hydrogen direct reduction is one of the technological process solutions for making steel, explored in framework reducing GHG emissions from steel sector (Net-Zero steel). However, there are many other solutions, which have been since 1980s or earlier. The present paper starts by comparing all these different options terms 3 criteria: energy needs, and total production cost steel. extensive simu...

Embryogenesis in Arabidopsis thaliana is marked by a predictable sequence of oriented cell divisions, which precede cell fate determination. We show that mutation of the TORMOZ (TOZ) gene yields embryos with aberrant cell division planes and arrested embryos that appear not to have established normal patterning. The defects in toz mutants differ from previously described mutations that affect e...
