The Church is covered with a wooden plastered ceiling which imitates the flattened dome, allowing the reduction of horizontal thrust on the enclosure walls.
Nondestructive testing in the form of thermographic camera provided data about the moisture level in the walls, as well as the hidden geometry of different elements.
As the Church is in good shape, all the recommendations here proposed are based on the further nondestructive or minor destructive tests and analysis, in order to acquire more accurate data and reduce the number of uncertainties.
Crack meters could be useful for this purpose, but it is important to store data long enough to exclude the effect of the environment.

The data which has been obtained with the help of the scanning electron microscope could confirm the results of optical microscopy.
Also the point of polymorphic transformation (1026 °C) has been determined from the data of a thermogram obtained using differential thermal analysis (DTA).
According to the data in Fig. 3, unconverted α-phase particles have a higher hardness at all quenching temperatures.
Reduction of the experimental determination process Tpt with the help of method trial hardening is achieved by decreasing of the number of samples to one.

The values of
bulk modulus are also in good agreement with experimental and calculated data.
The maximum reduction in shear modulus, almost 3 times, corresponds to the γ-TiAl - Cr(Al) system.

Experimental test has been played a crucial role in the design process of axial flow fan, and has been used in many aspects such as the determination of fan diameter, blade number, speed, blade shape, installation angle, and reduction of noise.
Although experimental assessing fan performance data can be obtained directly, long cycle and big investment are obviously the disadvantages.
Table 1 Fan performance data with different hub ratio Fan static pressure equals the whole pressure subtracting outlet dynamic pressure.
Table 2 Fan performance data with different blade number Fig. 8.

Most researchers choose empirically the choice of optimal concentration parameters by conducting a large number of experiments with subsequent analysis of experimental data.
Approximation of the experimental data given in the article [11] and in Fig. 1 by a polynomial of the form (2) where a, b, c, d are the approximation coefficients, the values of which are presented in table. 1, and the value of the coefficient of determination approaching 1, proves the same nature of the change in time of the driving force of the spreading process and the value of the dynamic contact angle, as well as the adequacy of the approach considered in this article.

The rate of reduction of the proppant pressure decreases due to insufficiently intense redox reactions leading to an increase in pressure P in the thin surface layer of the liquid between the particles.

Additional properties such as fire and ballistics resistance, signature reduction, and enhanced communications make them attractive for integrated structures.
By comparing the experimental data with the simulated ones according to the Fick’s law, the water absorption behavior of the resin casting can be described by Fick’s law accurately.
At the beginning of the immersion, the experimental data were a lower than that estimated by Fick’s law.
As the immersion time increased, the experimental data were slightly bigger than the simulated ones.

These processes have several advantages over other existing
commercial processes, such as uniformity of solute concentration, reduction of porosity and low
forming efforts.
From the temperature data, corresponding fraction of solid ( Sf ) is calculated by using non-equilibrium lever rule (or Scheil equation) [1, 2] as k LM M Sch S TT TT f − − − − −= 11 1 (4) where k is the partition coefficient of the alloy, 0C is the initial alloy composition , MT is the melting point of the pure solvent and LT is the liquidus temperature at 0C of the alloy.
Using the data given in fig. 2, the increase of viscosity with cooling rate is plotted, as shown in fig. 3.
The data for fig. 5a are extracted from those of fig. 2 and fig. 4.

The obtained results clearly show that the increase in the strain temperature from 900 to 1000°C causes the intensive reduction in the peak stress σp for FeAl alloy. 0 50 100 150 200 250 300 0 0,2 0,4 0,6 0,8 1 1,2 Strain εεεε Flow stress σσσσp, [MPa] FeAl 1000°C Fe3Al-Cr 1100°C 900°C Figure 2.
In a majority of the dependences developed so far, only data of average parameter values have been introduced, i.e. the average grain size, which resulted mainly from equipment limitations.
Data from measurement of the misorientation angles and the recrystallized grain size will be introduced into the cellular automaton model, which will facilitate a verification of the dependencies between the deformation process variables and the structure of hot deformed FeAl alloy.

Further data capture from the transducers yielded pure white
noise, with no bursts of wave forms or modulation.
One of the seal units Data Acquisition System Physical Acoustics Corporation WD transducers were employed.
With the seals at their datum positions, a 5 mm gap existed between the fin tips and the rotor.
This was due to a continuous reduction in contact pressure as the seal and rotor wore.
Several rubs were initiated before the seal was finally backed off to its datum and the test repeated for the other seals.
