An additional quality control measure, principle component analysis, indicated that mutation status of the EGFR pathway is not simply driven by population structure (Additional file 1: Figure S1).
The use of different response functions to be optimized in the frame of the use of near infrared spectrometry for quality control of active principles in agrochemical formulations has been evaluated.
Inspired by biological systems, the proposed quality control approach utilizes immunological principles as a means of developing the required mathematical framework behind the self-correcting methodology.
He plans to send Indian workers to Oppama for training in everything from how to tighten a bolt to the principles of quality control.
But even if companies had implemented the traditional principles of quality control more rigorously, it is doubtful that U.S. consumers would be satisfied today.
Indeed, there was nothing in the principles of quality control to disabuse them of the idea that quality was merely something that could hurt a company if ignored; that added quality was the designer's business a matter, perhaps, of chrome and push buttons.
Moreover, radiologists will ensure the appropriate use of equipment and quality control, and apply radiation protection principles which are particularly pertinent with the massive increase in the use of multi-detector CT [3].
In essence, we provide a guide to use the GMAP chip as well as highlight the design principles and quality control measures that may be useful for other customized microarray platforms.
These values have been used for calibration in quantitative analyses of historic glasses and to check the accuracy of the methods used, although the principles of quality control were not always sufficiently documented [ 33, 40– 40].
As a final quality control step we performed a principle component analysis and plotted the first two principle components to show that replicated samples were grouping together.
