However, the relative concentrations of the analytes in test samples may not be known a-priori, or may change from sample to sample; therefore, it is not always possible to construct QC samples that exactly mimic the relative concentrations of analytes in the test samples.
Our goal being to provide samples that will mimic real life situation as radiotherapy treatment, we irradiated our samples using the linear accelerator (LINAC).
"Work sample tests that mimic the kinds of tasks the candidate will be doing in the job" are the best "indicators of future job performance," according to Bohnet.
Through simulation studies, they tested five sampling methods that could be applied in the absence of a list sampling frame to provide samples that aimed to mimic simple random samples.
Further work will evaluate in detail the maximum depth achievable with the proposed method using tissue samples or phantoms that mimic the acoustic attenuation of tissue.
Overall these analyses show that small molecules and metabolites undergo significant time-sensitive alterations when exposed to elevated temperatures, especially those conditions that mimic sample preparation and analysis in GC/MS experiments.
To determine if samples with high artefacts contain mutations that mimic actionable mutations, we selectively examined the variant calls from samples with high artefact rates.
Susceptible phytate was determined by exposing the feed samples to conditions that mimicked the average pH of the proximal gastrointestinal tract (pH 4.5) and the optimum temperature for phytase activity (37 °C) and then measuring phytate dissolved.
A common method is the so-called T-history method [1, 16, 24, 25, 26], in which a PCM sample is studied in conditions that mimic the operational use of PCMs: its response to a changing environment is recorded.
Fig. 4 is a plot of results from model calculations that mimic the Cu and Sn deposited limestone wedge samples.
