Investigators produce them by performing measuring and other experimental operations and assigning symbols to perceptible results according to pre-established operational definitions (Duhem 1906, 19).
Observers may have the good fortune to obtain useful perceptual evidence simply by noticing what's going on around them, but in many cases they must arrange and manipulate things to produce informative perceptible results.
At this point, an estimate length of study to see perceptible results should be determined as well as valid control groups and an adequate analysis technique.
Taken together, these results indicate that loss of Jak2 only selectively inhibits the potency of DCs to initiate innate immune response without perceptible effect on DC-mediated adaptive immune response.
Overexpression of one of the putative orthologs, PopNAC154, resulted in a decrease in height and an increase in the proportion of bark to xylem in poplar trees, with no perceptible effect on SCW thickness [ 31].
At the hospital level, our results indicate that patient-based/casemix payment reduces the average length-of-stay by approximately 4%, and the bed-occupancy rate by 5% (with no perceptible effect on inpatient admissions).
The nonlinear dynamic introduced through this simulation is significant and perceptible in sound results for sufficiently large excitations.
Larger values of Δ would result in perceptible interference from other sources in the target source.
The morphological traits associated with race, thus, were gross aggregates of a variety of genetic changes, some of which resulted in physically perceptible characteristics, many others of which resulted in imperceptible changes.
Human influence and its impacts are perceptible in all ecosystems resulting in land transformation, changes in global biogeochemistry, climate change, and loss of biological diversity.
