Only few of the STP sample series were conversely removed via majority voting during the blank subtraction step, i.e., series fractions of 0.10 ± 0.06 (positive ionization mode) and 0.07 ± 0.03 (negative ionization mode).
Some of my classmates took the idea of "no blank slates" one step further.
The fable about a Japanese artist spending days staring at a blank sheet before stepping forward to inscribe a single, flowing mark on its surface comes to mind.
Just as reagent blanks are needed for assessing contamination during the analytical steps, field blanks can be used to assess potential contamination during sample collection, storage, processing, and/or transport [ National Institute for Occupational Safety and Health (NIOSH) 1994].
The exercise on 21 April saw armed police firing blank rounds on the steps of Cannes's celebrated Palais des Festivals, as a group of "terrorists" ran towards the buildings.
Reduction and control of blank data are important steps in quality control when analyzing PFCs at ultratrace levels.
The completion examples were partially worked out, with the last few problem-solving steps left blank for students to complete.
According to standard protocols for work with low quality/quantity DNA [ 17], contamination was monitored at both the extraction and PCR steps by blank controls and all post-PCR procedures were conducted in physically distant laboratories.
Through analysis, forming the ring with stepped-section blank is put forward, and a theoretical method to design the blank size is established.
Not only the influence of the connection, blank-holder force and the friction, but also the influence of the offsetting of the strain neutral layer with different radius of curvature at local area, are considered in the model, which improves the calculation precision of the blank shape at each step.
