All samples were subjected to different grades of work-hardening with the use of cold-rolling (0%, 5%, 10%, 13%, 15%, 20%, 26% and 34% reduction of initial thickness of their cross-section).
The Barkhausen noise analysis equipment arrangements, in short, consisted of an electromagnet that produced the magnetic field, a spool wrapped around its core in order to serve as an indicator of the proper conjunction between the surface of the samples and the censor, a second spool containing a ferritic cylinder in its centre, positioned between the two far ends of the electromagnet, that serves as the receiver/censor, an AC generator and DAC data collecting card that is connected to a PC, receives, amplifies, processes the input of the censor and gives us measurements: the counts (number of jumps of the Bloch walls occurred at a given voltage threshold), the power of the signal of the BHN (rms) and a qualitative indication of the magnetic permeability of the samples.

The detail understanding of the statistical nature of magnetic properties’ response and their attribution to certain structure changes in microscopic level, is essential in order to commercially exploit a reliable, high sensitivity Magnetic NDE method and fill the gap of a simple, first principles derived equation of state, which quantitatively interprets the actual magnetization data.
The misorientation distribution functions reveal a critical value of reduction ratio, where plane misorientations start to distribute in space without an evident preferred orientation (magnetic degradation), an effect that becomes more intensive with increasing cold rolling deformation.

It should be noted that such way of reduction of coefficient of heat transmission is effective for new producible panels and cannot be recommended for already existing objects.
We will illustrate the received results for the panel with continuous "the cold bridge" with experimental conditions and the data of its processing provided in [2]: Results of calculation for active thermal action on joint are summarized in Tables 1 and 2.

If fs is the fraction of electrons used for cell synthesis and fe the fraction of electrons used for sulfate reduction, then the overall biochemical reaction R can be written as follows [2]:
(Eq.4) where (Eq.5)
By combining equations - , the overall biochemical reaction is written as follows:
(Eq.6)
Ignoring biomass formation (i.e. fs=0) leads to the simple chemical reaction:
(Eq.7)
In the absence of experimental data, maximum values of fs denoted as fs0 can be estimated by thermodynamic analysis [1].

In electrical engineering, rapid prototyping is used due to the continuous reduction in the size of components, which are very complicated to manufacture.
Finally, it has the advantage of very fast data retrieval for preparation and production.
