Therefore, choice of long-term display, permanent storage or repeated displays of PB artefacts in air alternated with storage in the dark to let PB recolor, should be principally motivated on the basis of the type of textile and the state of degradation of the textile.
It is quite possible that the placebo may have had little or no effect, and was simply an artefact of repeated citric acid challenge.
In the cool of the evening my muscle memory is still swaying, an artefact from the repeated left and right arc of cutting hay on the meadow bank.
It is unclear whether this represents the differential antigen processing of pathogen associated proteins experienced in vaccination in contrast to infection, or if it represents an artefact of the repeated AVP vaccinations which may have served to skew the cytokine environment present during the induction of the immune response, impacting upon the T cell epitope repertoire [ 35].
However, given that preferential amplification of the smaller product may produce data artefacts, the study was repeated using real-time PCR (with Sybr green as the reporter dye) on the MX3005P thermal cycler (Stratagene, UK).
Because its temporal and spatial characteristics are similar across repeated cardiac cycles, a commonly used pulse artefact correction method involves the computation of an artefact template by averaging the waveform at each lead across multiple cardiac cycles [Allen et al., 2000].
All participants took part in two fMRI sessions at intervals of at least one week to reduce memory artefacts occurring due to the repeated presentation of the stimuli.
To check that the density decrease between seed sites and flanks was not an artefact of the method, we repeated our SNP density analysis 1000 times by sampling 2043 random motifs of seven nucleotides and computing SNP distributions.
The electrode meets the requirements for contactless measurement, resistance to motion artefacts and possibility to make long and repeated recordings.
This was repeated with the phase-encoding direction swapped to exclude artefact.
