At existence in soil volume of a temperature gradient (not isothermal conditions), under the influence of gradT [not equal to] 0 there are additional streams of steam, water and heat which "being imposed" on isothermal streams, make the general mass transfer more complicated.
Isothermal calorimetry measures the heat a cementitious binder generates in a cement paste or concrete specimen as an indicator for the rate of reaction, which is key to engineering properties such as workability, set time and early strength development.
As an alternative to PCR-based methods, considerable attention has been given to isothermal NATs because they do not require thermal cycling, making them ideal for point-of-care testing devices.
