Example: "The new policy will allow the fixation of the company's assets in a more organized manner."

The purpose of this study was to introduce an improved customized mold consisting of 2 pieces to allow the fixation of molds to these sites.
The air tube tip of the instrument was rebuilt to allow the fixation of a mirror.
The tensioned small-diameter wires allow the fixation of small bone fragments and counteract the bending or torsional displacements that are adverse for bone healing.
First, it can allow the fixation of beneficial mutations on one copy, leading to neofunctionalization, while the other copy ensures the ancestral function [ 16, 19].
3) We cannot reject the hypothesis that other factors such as meiotic drive, a phenomenon poorly studied in bats, might have acted synergistically to allow the fixation of Tonatia rearrangements.
Under this model, relaxation of purifying selection is expected during the period of functional redundancy, and may allow the fixation of at least two complementary degenerative mutations (one in each gene).
This might have promoted rapid sympatric or allopatric speciation, and allowed the fixation of unique morphological characters in Leymus.
The scaffold design allows the fixation of the implant by suturing the scaffold lid to the surrounding periost tissue so no implant movement occurs.
Initial functional redundancy relaxed the selection on one or both of the copies of this gene, allowing the fixation of an inactivating pseudogenization event.
Smaller population size decreases the efficiency of purifying selection, allowing the fixation of insertions that otherwise would have been eliminated in a population with a large effective size.
SDR regions in plants tend to be pericentric as is the case of papaya or telomeric as seen in poplar, as these regions typically have lower rates of recombination which allows the fixation of sex-determination loci.
