Cooling Curve - an overview | ScienceDirect Topics

Depending on system or procedure used for recording the cooling curve, different analyses are possible. A large number of characteristics can be recorded or calculated, such as maximum cooling rate, temperature at which the maximum cooling rate occurs, cooling rate at 300 °C and cooling times to certain temperatures (e.g., 600, 400, and 200 °C).

Temperature and Water - USGS

2019-6-8 · Fish, insects, zooplankton, phytoplankton, and other aquatic species all have a preferred temperature range. As temperatures get too far above or below this preferred range, the number of individuals of the species decreases until finally there are none. Temperature is also important because of its influence on water chemistry.

The Influence of Temperature on the Biogas

The still common understanding assumes the existence of a mesophilic (35 – 40 °C) as well as a thermophilic (50 – 55 °C) temperature range for the biogas production. More stable biological process conditions should be enabled by the mesophilic range, the thermophilic range is said to be faster and to produce more gas. 20 []

Influence of cooling rates and plunging temperatures

The temperatures of the freezer (T(chamber)) and of the semen (T(semen)) were measured simultaneously. We first tested two-step freezing protocols with different cooling rates (-2, -5, and -10 degrees C/min) and different temperatures at plunging into liquid N2. The difference between T(semen) and T(chamber) increased with faster cooling rates.

Impact of Temperature on Intel CPU Performance

While we all know that modern processors need active cooling, there is actually very little official information on how temperature affects a CPU's performance. Do you really need a high-end liquid cooled setup to get peak performance, or is the little stock cooler that comes with most CPUs enough? In this article we will examine exactly how temperature affects CPU performance.

How Does the Cooling Rate of Igneous Rocks Affect

2020-3-27 · The crystal size in igneous rock formations is directly related to the cooling time of the magma. Therefore, crystal size can be a dependable factor in determining the conditions with which the rock was formed. For example, rocks that feature larger crystals were more likely formed at lower levels below Earth's surface.
