The phrase "axis of the alignment" is correct and usable in written English.
It can be used in contexts related to geometry, design, or any field where alignment and orientation are discussed.
Example: "The axis of the alignment must be carefully measured to ensure the structure is stable."
Alternatives: "line of alignment" or "center of alignment".
In both cases the symmetry axis of the alignment is along the polarization vector, e, of the exciting light.
In the case of protein-DNA complexes aligned by negatively charged phage, it has been shown that alignment is dominated by the electrostatic properties of the DNA and that, providing the DNA is minimally distorted (i.e B-form and not significantly bent), the long axis of the DNA is approximately parallel to the principal axis of the alignment tensor[13].
As the loop residues between residues 22 and 32 exhibit the largest 1HN/15N chemical shift perturbations upon DNA binding, we orientated the protein so that these loop residues face the DNA major groove while keeping the z axis of the alignment tensor along the long axis of the DNA.
3B and C), together with knowledge that the principal axis (i.e. the z axis) of the alignment tensor is approximately parallel to the long axis of B-form DNA, enables one to orient the protein on the DNA and obtain a crude model of the MA/DNA complex (Fig. 6).
In any case, an attempt is made to see that the trees cut along the axis of the alignment fall toward the outside of the road reserve.
The most time-consuming procedure was the mechanical axis of the stifle joint alignment with the mechanical axis of the testing device.
Before and after that date, a slow shift in Earth's axis skewed the alignment of the two stars with the celestial pole ever so slightly.
For Experiment 1, pair members were chosen so that the axis of alignment for the pair was either predominantly vertical or horizontal.
Aligned scaffolds displayed significantly increased expression of tenomodulin compared to nonaligned scaffolds and exhibited aligned collagen fibrils throughout the full thickness, the presence of which may account for the increased yield stress and Young's modulus of cell-seeded aligned scaffolds along the axis of fiber alignment.
The reason might be due that the growth orientation of the LT-GaN columns is not ideally align along c-axis, and the alignment of the subsequently grown InN nanorods is further worsen.
Over time, anisotropic growth along one of the <100> axes would rotate the [100] axis of elongation into alignment with the chain axis [100], so that the [100] fiber orientation should become more pronounced with time.
