Example: "In the experiment, we decided to use an alternative apparatus to achieve more accurate results."
Alternatives: "substitute device" or "replacement equipment".
Obama emerged from the campaign having assembled what was essentially an alternative apparatus to the party itself — a closely guarded, state-by-state list of more than 10 million names, many of them door-knockers, phone-bankers, letter-writers and small-dollar donors.
This increase in channel size results in a corresponding decrease in mixing intensity and so alternative apparatus designs and nucleation control techniques are required to recover control of assembly conditions.
Based on the obtained results, the statistical relations between the two alternative apparatuses were then thoroughly described.
For this reason, we have used an alternative simple apparatus, minimizing the edge effect (Figure 1).
Our data suggest that gliding motility and the formation of a moving junction (or an alternative invasion apparatus) requires machinery that is specifically adapted to breaching the enterocyte surface barrier for every cycle of replication, egress and invasion.
When months of checking the apparatus produced no alternative explanation, the scientists concluded that they had indeed found a five-quark particle.
Using a two-action apparatus, we established alternative behavioural patterns in six family groups composed of 36 individuals.
Although the Loeb edition occasionally notes a textual difficulty or an alternative reading, it provides no systematic apparatus criticus.
Furthermore, this work illustrates the advantages of using a novel analytical method, the LDTD-APCI-MS/MS apparatus, which is an alternative approach to chromatographic methods.
In the first of two experiments reported here, we tested whether female zebra finches taught one of two foraging techniques showed a preference for males with the same or the alternative technique in a mate choice apparatus.
We studied the triceps reflecting approach (TRA) with preservation of the extensor apparatus as a safe alternative giving a sufficient exposure to the elbow joint and helping to achieve anatomical fracture reduction with the intact olecranon as a template.
