Sentence examples for upper temperatures from inspiring English sources
Thermal cycling with upper temperatures over 500°C may also result in structural damage.
We found that carapace temperatures were greater near structures (fence or unfenced road) than away from structures; tortoises near the unfenced road had higher mean carapace temperatures, but tortoises along the fence experienced more extreme upper temperatures that approached the species' thermal limit.
The column temperature was programmed from 70°C to 280°C at a rate of 20°C /min with the lower and upper temperatures being held for 3 and 10 min, respectively.
These temperatures were chosen to represent lower, medium and upper temperatures experienced by developing grayling larvae in nature [ 52], and thus we would be able to investigate norms of reaction covering the range of temperatures that grayling may be expected to tolerate.
