Thus, by analyzing only data on the powder bulk density (packed density)it is not possible to make unique conclusion in order to choose the optimum processing time of the powder mixture in the PBM.
The data of the measurements are presented in the form of a histogram in fig. 2.
This fact is well consistent with numerous literature data on the treatment of powder mixtures in the PBM, and can be interpreted as the result of particle agglomeration.
Thus, using the data presented in Fig. 2, it is possible to make the following generalization: 1.
The additional comparison with data of Barkhausen noise measurement suggests that there are practically no metal particles in the composite coating.

The Ni-Cu-Mo electrodeposition process is accompanied by the hydrogenation side reaction, which leads to a certain error in the results after data processing.
Despite this, the error can still be ignored when the data obtained from the test with the total current are processed due to the addition of sodium dodecyl sulfate and other additives into the electrodeposition solution.
Based on the data collected from the single potential step curve of trisodium citrate at different concentrations, as shown in Fig. 2, the results were plotted and compared with the nucleation Models (1) and (2), as detailed in Figs. 3 and 4.
According to Figs. 3 and 4, the experimental data obtained without and with the addition of trisodium citrate are consistent with the theoretical value of transient nucleation before the current peaks (t/tm≤ 1).
(3) Based on the data of the i-t curve in Fig. 1, the im at each step potential can be determined, as shown in Tab. 1.

Jeon et al. [26] in their study evaluated the formation of σ and χ phases in ingots with the addition of alloying elements such as Cu, W, and Ce in HDSS, observing a reduction in the formation and sigma phase with the increase in the χ phase.
This work can be used as a source of data to increase operational safety in demands that require applications in severe corrosion environments. 2.
For the χ phase, a slight phase formation growth is pointed out from 60 to 180 min, with a slight reduction after this time.
The presence of precipitates promoted the decomposition of α with a reduction in the value of alloying elements essential for maintaining corrosion resistance, making this region more susceptible to corrosion.
Availability of data and material The authors confirm that the data supporting the findings of this study are available within the articles used as a reference and supplementary materials.

Modulus results show the simulation data slightly exceeded the actual data.
The predictive simulation results were inconsistent with the actual experimental data.
The sample was extracted from the lowest speed sample (2 m/min) to find the performance reduction.
The researchers submitted that the commingle yarn resulted 3 % reduction of young modulus in warp direction while 17 % reduction in weft.
A major reduction of tensile modulus capability in weft direction than warp is because the commingle yarn committed more yarn interlacing on the weave structure.

The experimental data were fitted using Pseudo-first order (PFO) (Eq. 1) and Pseudo-second order (PSO) (Eq. 2) reaction rates.
This is related to the specificity and targeted removal of the dye by Fe0-C particles compared to the Fe0 particles [14,28,29]. the reduction of the azo (N=N) bonds due to the oxidation of Fe0 likely causes the decolorization observed in the solution [30].
The PFO model fitted the RhB removal data best with an R2 value of 0.99 while the PSO model fitted the Cr (VI) removal data best with an R2 value of 0.88 [15, 35].

The former Soviet Union scholars, through sorting out plenty of survey data [6], obtained the approximate equation to calculate the allowed maximum deformation in the top of earth-body tunnel.
The statistic analysis for a large number of site-measured data obtained through investigations and the case analysis of cave collapse have proved that the sinking condition at the cave-arch top observes the same law, that is
a) Elevation drawing b) Cross section Fig. 2 Main geometric parameters According to the analysis of on-the-spot measured data, the cave span and mulching soil thickness have a dominant influence on the stressing characters of a cave structure.
In the meanwhile, the reduction of iterative times means that of required finite element analytic times so as to greatly increase the calculation effectiveness.

The
data show that the intrinsic breakdown
field for the annealed wafers is around
14MV/cm and is similar to that of the
reference wafer.
Our Ds data obtained for annealing in H2 atmosphere at reduced pressure correspond well to the literature data [9] shown on the figure 8 for the comparison, while annealing in Ar leads to surface diffusivity 3-4 times higher, which may be explained by the reduction of surface atom mobility by Si-H bonds at the surface at low temperature.

There are not enough published TEM-data about structure-phase composition of coatings deposited by plasma detonation.
According to the XRD data the material of the substrate contains a Fe -based bcc-lattice phase (cubic, Im-3m, 229) with the parameter a=2.8662 Å.
According to the XRD data the PG-19N-01 coating contains a Ni-based fcc-lattice phase with the parameter a = 3.525…3.540 Å (Table 1).
The estimated fcc-lattice parameter of CrNi3 (Fig. 3b) in the coating made a= 3.58 Å (the interplane distance is 2.05 Å), which is very close to the XRD data (Table 1).
Such an effect was observed by researchers in data [11, 12] devoted to research of nanostructure films.
