However, when we forced foxi3a expression in bmp7 morphants, it was sufficient to restore both NaRC (100%, n = 62) and HRC (100%, n = 62) differentiation with high penetrance (Figure 8G).
The human HRC plasmid (pcDNA3.1-HRC) was purchased from Genechem (Guangzhou, China), and small interfering RNA (siRNA) was synthesized and purified by RiboBio (Guangzhou, China).
However, when we forced foxi3a expression in Notch-ON embryos, it was sufficient to restore both NaRC (100%, n = 74) and HRC (100%, n = 74) differentiation with high penetrance (Figure 8D).
The Ni-P-Cu-coated specimens serve as test specimens of average hardness of 42 HRc, which are held horizontally against a rotating roller coated with titanium nitride of hardness 85 HRc of 50-mm diameter × 20-mm thickness, as shown in Figure 2.

It was hardened to 60 HRC.
Additionally, the optimum cutting conditions for the materials with 50 HRC and 62 HRC was found at different levels.
A steel disc of En 31 with hardness of 60 HRC was used as the counterface.
The roller material is GCr15, and the roller surface hardness exceeds 60 HRC after quenching.
The overall objective of this study was to conduct a systematic and comprehensive experimental investigation to evaluate and quantify forged surface finish effect at several hardness levels (19 HRC, 25 HRC, 35 HRC, and 45 HRC) on fatigue behavior of a commonly used forged steel.
This paper focused on optimizing the cutting conditions for the average surface roughness (Ra) obtained in machining of high-alloy white cast iron (Ni-Hard) at two different hardness levels (50 HRC and 62 HRC).
