The needles were inserted through the spinal cord parenchyma to reach the ventral aspect of the vertebral canal and this position was ascertained using fluoroscopy and observing cerebrospinal fluid dripping from the needle hub (and, in some cases, injections of radiographic contrast agent were used to ascertain correct positioning within the vertebral canal).
In between each set of samples two standards of a 5 Angio mix peptides (Michrom Bioresources, Inc., Auburn, CA) were run to ascertain column performance, and observe any potential carryover that might have occurred.
In between each sample, a standard of a 5 Angio mix peptides was eluted (Michrom BioResources, Auburn, CA, USA) to ascertain column performance, and observe any potential carryover that might have occurred.
Comparative morphological analyses within a phylogenetic framework help to unravel the complex patterns of skeletal morphological evolution [ 8- 10] and are essential for 1) assessing evolutionary trends [ 10, 11], 2) inferring changes in rates of evolution [ 12], and 3) ascertaining whether observed similarities result from common descent or are acquired independently [ 8, 13].
Thus this rate can be ascertained and projected.
They checked, corrected, ascertained and re-ascertained the data.
Calibration ascertains the concordance between the model's predictions and observed outcomes, which we evaluated using a calibration plot.
In order to ascertain if our design was effective, we collected and analysed student feedback (through interviews and questionnaires) and behaviour (self-reported through feedback and questionnaires and observed by the researchers).
Hence, the performance of the system can only be ascertained by observing the results by probing the exposed interfaces which include the globe system performance and the external resources.
For Rorty, warrant is a "sociological matter, to be ascertained by observing the reception of [a speaker's] statement by her peers" (1993: 449).
