But there were two competing graphs – Mann's hockey stick and another, by Phil Jones, Keith Briffa and others, which sought to ascertain temperatures over the past millennium using, among other things, tree rings, ice cores and coral.
Acid base properties of these catalysts were ascertained by temperature-programmed desorption (TPD) of NH3 and CO2.
Thus, a mother suspecting her child is feverish may use a thermometer, in which case she ascertains his temperature by looking at the thermometer, rather than by directly touching his head.
To ascertain whether temperature transcriptionally influenced NRKe and 9RKe, we comparatively analyzed the expression of NRKe and 9RKe in wild-type plants at different temperatures.
Finally, we ascertained the local temperature changes of the film samples upon laser heating as a function of the global temperature, demonstrating significant differences in the heating process, suggesting that heat evacuation efficiency depends type of the film, its thickness and global temperature.
We were unable to ascertain the temperatures with the heated lid closed, but based on comparisons water bath measurements, the temperatures with the lid closed slightly exceeded the indicated temperatures.
Attachment is a complex process and the limited number of strains and conditions used in this study along with the level of variation recorded make it difficult to ascertain precise temperatures for minimizing attachment.
For each SIDS case, the researchers ascertained the maximum temperatures on the day of and the day before death.
To ascertain the conditions under which these substitutions are adaptive, fitness was measured by a variety of methods for several bacterial hosts growing at two temperatures, the control temperature of 37°C and the selective temperature of 42°C.
Furthermore, we ascertained the optimal annealing temperature of 32 sets of primers.
