Results and discussion
In present paper the experimental data is presented on the catalytic activity of catalysts for the process of aromatization of n-paraffins from the zeolite deposit of Shankanay field, which is based on the selective recovery of transition metal ions at low temperatures under the influence of mechanical treatment.Taking into account, that the low temperature recovery is very selective resulting in the formation of surface low-coordinated ions, we can expect interesting catalytic properties in such systems.
Table 1 shows the experimental data on the influence of the degree of dispersion on the acidic properties of zeolite catalysts modified by nickel, copper and zinc.
Apparently, Zn2+ cations are localized mainly within the zeolite channels, forming acid-base pairs of the type Zn2+-O2- [56].Whereas, the preliminary grinding of the zeolite leads to reduction of the possibility of penetration of zinc cations into the zeolite channels, and therefore a smaller number of protons of strong acid OH groups are replaced by Zn2+.

Apparently, the almost fourfold reduction of the size of coherent-scattering regions D, as seen from the last column of the table 1, influences the Нc growth upon the upsetting.
The results of the TEM analysis are in agreement with the XRD data.
Data on the phase structure, volume fraction, lattice parameters, coherent-scattering region D for tetragonal Р4/mmm (P), I4/mmm (I) and cubic Fm-3m (fcc) phases and in traditional fct – representation (given in parentheses).

Shah and Kobayashi [4] performed FEM simulation to analyze the head of screw forming, the results to compare the experimental data to verify the acceptance of simulation.
The results show the half die angle and reduction ratio really affects the head forming and forging force, and the forging force has the influence to dies life.
Weronski [14] reports to realize that the simulation data can feedback to the realistic forming to improve the product defect.

The measurement data obtained is graphed with the relationship of Load Mass & cut angle with roughness and amplitude value.
The purpose of this research is to find out the effect of passive mass reduction and the cutting angle of AISI 1045 Steel on the roughness and amplitude values.

Data was collected with 256 data points per line.
Data represents the mean percentage of HES cell colonies from eight plates that stained positive throughout for high alkaline phosphatase activity +/-SEM (note: data for "textured" substrate refers to a mean percentage of cells staining positive for AP on all six patterned surfaces).
Data represents the mean percentage of HES cell colonies from nine plates that stained positive throughout for high alkaline phosphatase activity +/-SEM (note: data for "textured" substrate refers to a mean percentage of cells staining positive for AP on all three patterned surfaces).
Discussion These data show that topographical features of the nanoscale level impact HES cells profoundly.
Our data suggest that surface topography represents a fundamental and important parameter that can be exploited in the culture of human embryonic stem cells.

Remember the data for nickel diffusion in silver measured by Bernardini group.
Bokstein: All these data are tracer data?
You obtained extraordinary data on iron grain boundary diffusion in copper.
Divinski: There are some data from Cermak group.
Really, the most of the simulations data are for very special grain boundaries, for very obvious reasons.

Reduction in Fe3O4 and Fe2O3 is accordingly observed.
Apparently from data in Fig.2, the fine-grained structure is formed mainly in the processes, which have been carried out in zero electrical fields.
It corresponds to data in Fig.3 where the coercive force value is large in the absence of the field, and noticeably decreases with field strength.
XRD data showed clear differences between the metallic and non-metallic parts.
Furthermore, we can infer from the X-ray data that the reaction proceeds via intermediate phases.
