The phrase "a component appears" is correct and usable in written English.
It can be used when discussing the presence or emergence of a specific part or element within a larger system or context.
Example: "In the latest version of the software, a component appears that enhances user experience significantly."
Alternatives: "a part emerges" or "an element is present".
For example, molecular data loaded into a Viewer component is displayed as a static 2D Lewis structure drawing, whereas the same data in a Rotator3D component appears as a 3D rotating molecule.
- If the nodule size increases by at least 2 mm or if a solid component appears, the test is positive, and the subject is referred to a specialist [ 43 ]. - If a pure ground-glass nodule is stable, the test is indeterminate, and management is subjected to multidisciplinary discussion.
In the spectra of electrodeposited alloys a new component appears at low temperature.
In the case of three dimensional steel joints with additional plates welded to the weak axis, a new component appears.
CEMS shows that the transition from superparamagnetism to ferromagnetism in the precipitated iron nano-clusters critically depends on the implantation dose and post-annealing and that with increasing dose over 2.0×1017 ions/cm2 a ferromagnetic component appears in the Fe implanted MgO samples.
Ground-glass opacities were not considered in this study until a solid component appears.
These findings indicate that, in the wild-type mice, there is little evidence for an NR2B component in the synaptic NMDA receptors, but that an NR2B component appears in the synaptic NMDA EPSC during 20 min perfusion with magnesium-free solution; this increase in the NR2B component was not observed in P2X4−/− mice.
A strong paramagnetic component appears on samples 1 h, 1 h.Cal, and 1 h.Et.Cal which is attributed to the formation of V2O3 on sample 1 h, and secondary phases containing V+3 ions on samples 1 h.Cal and 1 h.Et.Cal.
Laboratory measurements on CO mixtures with other gases deposited on a flat substrate at low temperature have shown that the middle component occurs in mixtures dominated by non-polar molecules (CO2, O2, N2) and that a broader reddish component appears in mixtures dominated by polar molecules, such as H2O, NH3 and CH3OH (Tielens et al., 1991; Palumbo et al., 1995; Ehrenfreund et al., 1996, 1997).
Nevertheless, it comes to light that a random component appearing in an external excitation can influence significantly the effective aeroelastic stability of this system.
