The phrase "admixture levels" is correct and usable in written English.
It can be used in contexts related to chemistry, biology, or any field where the combination of different substances or elements is being discussed.
Example: "The study focused on the effects of different admixture levels on the strength of the concrete."
Alternatives: "mixture ratios" or "blend proportions".
A considerable influence of oxygen addition on the formation of clusters was observed even at oxygen-to-argon admixture levels of the order of 1 1000.
One potential caveat with the African-American result lie in the fact that this population is admixed with Europeans, and that admixture levels can be variable.
We find a highly significant difference between these two means [t-test: t(478) = −13.618, p = 1.51×10−36], indicating that, on average, observers are able to estimate admixture levels from photographs better than chance.
Most of the individuals showed high admixture levels among the 3 clusters.
In which case, current admixture levels of this population are the result of earlier hybridization events.
Such an approach may allow predicting admixture levels before supplementation operations and thus significantly improves management strategies.
In addition, increasing the number of inferred clusters allowed to confirm the high admixture level and assumed origin of some populations (see above) such as West African hybrids (BOR and KUR) and zebus (ZBO and ZFU), SHK (which displayed similar characteristics as West African zebus [19]), OUL and synthetic breeds.
Of the three populations, BRATG showed the highest Southern European admixture level (~45%%) while BLCAP showed the lowest (~26%%).
This model was used to test for any differences in the condition index, between lakes and years and along the admixture level of fish.
We identified four regions that were significantly associated with a blood pressure trait at the genome-wide admixture mapping level.
The results that will be presented herein have allowed a good mechanical characterisation of the referred aggregate, in terms of the estimation of combinations of the cement content and the admixture compaction level, resulting in new correlations for design purposes.
