Five replica tests were made for each scaffold.
In the microarray experiments, biological and technical replica tests were carried out to gain raw data for statistical analysis.
Thus there is raised a serious question concerning the reliability of quantitative data published in bacterial mutagenicity testing where replica testing of the histidine requirement of the resulting "revertant" colonies is not routinely made.
The aim of this study was to analyze and to compare the fracture type and the stress at failure of clinically fractured zirconia-based all ceramic restorations with that of morphologically similar replicas tested in a laboratory setup.
A separate Beadchip was used to perform a technical replica experiment, testing the same pooled RNA sample with two separate arrays and to test pooled lumbar cord samples from G93A SOD1 mutant rats and from WT littermates, at 10 weeks of age, at onset and at end-stage disease.
There are a few other uncrewed satellites or robotic probes in that gallery, but they're all replicas or test hardware--the real ones burned up on reentry or are still out there in space.
Nonparametric bootstrap resampling (BT) [31] was performed with 1,000 replicas to test the robustness of the tree topology.
At least three replicas were tested at any given time, exposure, and loading conditions.
A strong influence of the microstructure on subsequent fatigue crack growth is observed from interrupted testing with replica records and SEM examination of tested samples, with cracks exhibiting significant tortuosity, at times even appearing to grow approximately parallel to the tensile axis.
Crack advancement was checked with the plastic replica technique, during test interruptions.
A model that is a replica of the test vehicle is executed – in real-time- where all hybrid power train modules are included.
