Although the lethal thermal limit
often decreases with extended exposures, possibly biasing this comparison toward finding lower larval tolerances, two lines of evidence suggest that this cannot account entirely for this result.
At this point, there is a cellular transition from aerobic to anaerobic metabolism; therefore, the critical thermal limit
becomes a match when the aerobic scope is close to zero.
In addition, the combination of planetary and helical-bevel gear units translates into an optimum power/weight ratio, in addition to an improved thermal limit
rating by means of a shared oil chamber.
ii) No element has violated its thermal limit
during any contingency.
Nevertheless, if the range of the fluctuation became very great, egg development should be inhibited if daytime temperatures rose to the upper thermal limit
or nighttime temperatures decreased to the lower thermal limit
For comparison among species, a thermal limit
was taken at which more than 70% of the embryos reached successfully the end-point of the experiments (see above), as a more restrictive parameter than the commonly used 50% of survival of embryos [1, 9, 20].
This same product also has an upper temperature thermal limit
of +125 deg C, which ensures that internal surfaces of pipework, tanks and vessels can be safely subject to steam or high temperature chemical cleaning without detriment to the insulation materials.
NRC regulations set a fuel thermal limit
of 2,200 degrees Fahrenheit for "peak cladding temperature" under predicted loss-of-coolant accident conditions.
A seal's thermal limit
can, however, be extended to meet almost any pump system requirements by upgrading the seal material to a thermopolymer or PTFE.
In other words, the desired power flow in the interconnection is greater than the thermal limit
. Power of overload is usually calculated for the initial operating state:
