Furthermore, energy systems are increasingly being regarded as service providers rather than pure technical artefacts.
However, the pathological findings indicative of ischemia encountered in other stress tests support the interpretation of hypoperfusion as a potential cause of the FP results and argue against pure CMR artefacts.
It is only when the mobilisation of this resource is complete that it considers a central prerequisite of utopia as fulfilled: namely, the material reproduction of the society, which evolves from "labora!" (labour) and not from "ora!" (pray) and which therefore sees itself as a pure human artefact.
In contrast to exudation methods that are prone to contamination, phloem-feeding insects, such as aphids, enable sampling of SE sap that is often referred to as the gold standard for phloem, being purest and least subject to sampling artefacts.
Zangger Sterk pure shift methods typically produce small (a few %) artefact signals, usually in the form of weak sidebands at multiples of the F1 spectral width SW1 (i.e., the inverse of the increment in t1) used.
However, one advantage besides others is the fact that 18F is a pure positron emitter without additional prompt gamma emission, thus avoiding halo artefacts introduced by this specific effect.
This artefact of 2D-PAGE has been noted in pure culture studies and may be due to several reasons, including strain variation, differential protein processing, posttranslational modifications, and protein degradation [28], [29].
Some of the increase in referrals and admissions over the years could also be an artefact of the delayed uptake of the database rather than a pure increase in admissions.
However, using pure dsDNA as a binding substrate in an anti-dsDNA ELISA remains a laboratory artefact.
For each primer pair, a preliminary real-time assay was performed on O. sativa or M. incognita pure and mixed cDNAs samples to evaluate the amplification of non-specific products or primer dimmer artefacts.
