The choice of the temperature range is made based on sintering temperature data under production conditions.
The data from FIZ/NIST ICSD database were used as structural models.
It can be seen, that the symmetry reduction (Fd-3, I41/amd) does not occur.
Table 2 shows the refinement data for both batches of the samples; experimental, theoretical and difference diffraction patterns are presented in Fig. 3 Figure 3.
The authors are grateful to Pavel Chizhov (Thermo Teсhno, Moscow) for help in experimental data analysis.

The observed diffraction pattern was in good agreement with the PDF-2Plus data of β-AgI (No. 01-078-1614), hence the crystal phase was identified as β-AgI.
The trajectory of the plotted data follows a semicircle.
The DC resistivity was estimated from the intersection of the data in the low-frequency region and the real axis, and DC electrical conductivity s was estimated by taking the reciprocal of the resistivity.

That is, it is concluded that this contraction is reflected in the reduction of ionic conductivity and the increase of activation energy.

Compared with conventional control strategy, the results showed that P-V-T control of precision injection molding could bring out more uniform density distribution, reduction in volume shrinkage and warpage of molded parts.
Therefore, we can modify the packing pressure according to the temperature data in the constant specific-volume packing stage.

The results show that the reduction of concentration of base solution and reaction temperature and the increase of pH value could improve the specific surface area of precipitation silica.
In this paper, in order to provide fundamental data and theoretical guidance in developmental research of new products and industrial production debugging of silica, the factors which influence the performance of precipitated silica in scaled-up reactor was studied systematically.

There are very few experimental data available for homogeneous nucleation in microcellular injection molding.
Table 4, summarizes the data for homogeneous and heterogeneous nucleation.
Homogeneous and heterogeneous nucleation data [32].
In absence of experimental data the solubility of gas may, roughly, be estimated by [43]; (43) Where, is the critical temperature of supercritical gas.
The reduction in the rate of gas diffusion to growing cell will limit its growth.

Thus, it is important to recycle and reuse such material, leading to less energy use and reduction of environmental impacts.
Their results show that there is a significant improvement on the soil strength and reduction of compressibility due to the plastic reinforcement in comparison with - pure soil.
In order to recycle the construction debris, important production steps were taken, such as selection, separation, size reduction and sieving.
At the plant, the RCA goes through selection, separation and size reduction processes and it is given out in three grain sizes.
The correction used the solver application on an EXCEL spreadsheet and all the gradation data from the sieve analysis.

Classe Apparent density (kg/m³) Energetic density (MJ/m³) E 1075.04 16298.65 P 1226.87 19414.84 Denser briquettes were obtained of the Class P residues (Table 3), possibly to the better compaction promoted by this material, which resulted in a reduction of the volume of the briquette to the same mass.
In this case, the following situations can occur as: increase of the internal electrical losses of the installation, decrease of voltage in the installation, reduction of the use of the capacity of the transformers and heated conductors [23, 25].
Table 4: Data for the determination of the direct price of briquette energy.
Considering the measures previously used in this work, the values would be 603.22 and 817.06 R$/ton, which translates into a reduction in the total cost of approximately 31 and 38%, respectively.
While using the previously used technique would have the full cost for Eucalyptus spp. would be 603.22 R$/ton and 817.06 R$/ton for Pinus taeda, which translates into a reduction of around 31 and 38%, respectively.

The satisfaction of needs of Ukraine in fuel and energy resources by means of increase of the part of own mining and decrease of external energy dependence by means of resources import reduction is one of the main purposes of the state energy policy put into action in the National energy program of Ukraine to 2010 [8].
The inadequate exploration work can result in the reduction of oil and gas production in future.
The implementation of energy supply measures, increase of produced gas volumes, use of nontraditional sources of energy, as it is planned in the National energy program [8], will enable reduction of natural gas consumption by economy and cut its import.
As the first-priority measures of energy saving provision the following measures should be considered: · development of State complex program of energy saving; · technical retooling of production; · creation of national non-budgetary fund for energy saving; · strict stocktaking and control of energy consumption of all branches of production; · motivation of energy saving technology implementation; · structural reconstruction of economy by means of reduction of share of energy consuming industries; · use of nontraditional and renewable sources of energy.
Industrial implementation of high-performance fully controlled power converters made it possible to control electric drive data and traditional indicators of power quality (reactive power compensation, minimization of higher harmonics levels, voltage stabilization and balancing) in an independent and separate way for the systems with reactive high-variable and nonlinear load (including high-power thyristor electric drives of rolling mills etc.) [10…12].

(a) W/B=0.35 (b) W/B=0.50 (c) W/B=0.70 Fig. 1 Total pore volume of concrete at various ages It can be found from the figures that the total pore volume of concrete decreases with the reduction of water-to-binder ratio and the growth of age.
The result is primarily due to the reduction of cement content.
When the age reaches 91 days (Fig. 2b), no matter what the pore size is, the corresponding intruded volume of all concretes have a obvious reduction, especially for the volume whose pore diameter is bigger than 0.1μm.
The pozzolanic reaction of fly ash has occurred at this age, but the 20% substitute ratio will cause a strength reduction.
In Fig. 6b, it is seen that the data distribution of gel pore volume versus strength are very scattered.

Liu et.al [11] have been shown that ZnO–graphene composites synthesized by microwave exhibit an enhanced photocatalytic performance in the reduction of Cr(VI) exposed to ultraviolet (UV) light irradiation.
Previous literatures [11-13] have been focused on optimizing the weight percentage of graphene in the composite, finding an appropriate post-treatment for reduction of graphene oxide and making heterojunctions between semiconductor-graphene components.
Lack of any peaks relating to GO at lower angles could be attributed to both the inconsiderable concentration of GO in the composites and complete reduction of GO to rGO after hydrothermal synthesis [21].
The preferred growth of ZnO nanoparticles can be estimated from X-ray data by comparing the relative intensity of (0 0 2) peak to the sum of intensities of other peaks of ZnO [22].
