A mathematical model of critical jet heights causing droplets splashing in BOF steelmaking
It is important to understand the physical interaction between top-blown oxygen jet and liquid bath in basic oxygen steelmaking furnaces (BOF). In this study, cold model experiments were carried out to investigate the cavity depth, diameter and the ...

The complexity of recognizing minimally tough graphs [PDF]
A graph is called $t$-tough if the removal of any vertex set $S$ that disconnects the graph leaves at most $|S|/t$ components. The toughness of a graph is the largest $t$ for which the graph is $t$-tough.

Investigation of the effect of preload on the mechanical properties of fiber-reinforced geopolymer concrete [PDF]
Concrete may be loaded at an early age for a variety of reasons. This loading can have negative and sometimes destructive effects on the hardened properties of concrete.

Influence of boron content on the fracture toughness and fatigue crack propagation kinetics of bainitic steels [PDF]
The relatively good combination of high strength and ductility makes bainitic steels a candidate to replace many other steels in industrial applications. However, in service, ductility and strength are not up to standard requirements.
