To ensure the prevention of the negative impact of such waste and ensure environmental safety, the global community adopted the following hierarchy of the waste management (by priority): maximum use of feedstock and raw materials; prevention of waste generation; reduction of formation and reduction of the hazard class in the sources of their formation; processing, disposal and neutralization.
Reporting and statistical data, as well as the information received by scientists and specialists of the Federal State Autonomous Body “Research Institute” Environmental Industrial Policy Center” when developing the forecast of the development of the industry for processing, disposal, neutralization of production and consumption wastes for the period up to 2030 were used in the analysis.
A significant contribution to the research results was made by monitoring the enterprises that form the mentioned types of waste, the state of their territories and storage and accumulation areas, as well as the data obtained using geoinformation methods, methods of geometrical sounding of objects from the Earth and space [6,7].
Data on organizations that carry out neutralization and disposal of extremely and highly hazardous wastes are disaggregated in territorial schemes and regional programs for waste handling of the subjects of the Russian Federation, Information and technical reference books on HLAT: ITS 15-2016 “Waste disposal and neutralization” and ITS 9-2015 “Neutralization of waste by thermal method (combustion)”.
The gasification reactor (gas pressure reduction station) converts highly toxic inorganic components into molten slag and the organic components of the mixture of hazardous waste into synthesis gas at a temperature of 870°C, with a pressure close to atmospheric pressure, and a volume of 64 to 69 thousand Nm3 per hour.

The surface area, in turn, is directly associated with a reduction in average particle size and average crystalline size, and, thus, can be achieved by milling.
(3) If surface energy plays the predominant role in the phase transition, then the strain energy terms (V) in Eq. 3 can be neglected and the critical diameter can be calculated using the following data reported for zirconia: γ(m) = 1130 ergs/cm2 [1]; γ(t) = 770 ergs/cm2 [25]; G(t)-G(m) = 1213 cal/mol (at 28 oC) [26]; ρ(t) = 5.86 g/cm3 and ρ(m) = 5.74 g/cm3 (calculated from XRD data [27, 28]); with a result of Dc ≈ 100 Å.
The authors assumed, that with reduction of particle size, mechanical treatment also produces simultaneous structural changes which are associated with amorphisation of the crystalline network.
This work provided valuable data on the mechanism of transformation under mechanical treatment, but still does not elucidate why the produced metastable t-ZrO2 is not nucleated and transformed back to monoclinic.
This experiment revealed only amorphisation of monoclinic zirconia even after 10 hours of milling, and a particle size reduction to ~10 nm (Table 1).

All electrodes were immersed in the MB solution then measured reduction current of MB via DPV every minute for ten times.
In this work MB was utilized with two purposes; first, the specific binding with ssDNA and, second, its sensitive electrochemical detection with low reduction potential.
In a series of experiments, MB 100 mM was diluted in supporting electrolyte (20 mM Tris-HCl:NaCl (10:1 v/v) pH 7.0) and various modified ITO electrodes were immersed and collected data every one minute.
Observing data from voltammograms (data was not shown), MPA cannot block all area of bare ITO.

For example, Kasarda [8] has demonstrated that the midspan use of an AMB as a "third bearing," or magnetic damper, for the reduction of up to three modes of rotor synchronous vibration.
In jet engines, the addition of one or two AMBs as additional bearings may add enough stiffness to the system to allow for the reduction of shaft diameters resulting in weight reduction and lower surface speeds for the rolling-element support bearings (resulting in longer bearing life).
A National Instruments PXI data acquisition system is used to capture input signals from the MB 350 controller and output signals from the Bently-Nevada ® proximity probes used to monitor rotor displacements at various locations along the shaft.
The PXI system is a stand-alone chassis that can accommodate up to eight different types of data acquisition cards.
The data measured from the PXI system will then be post processed using Labview, which is a National Instruments software package.

When the outdoor temperature was greater than 30℃ and the wind velocity was less or equal to 1m/s, the reduction greenhouse temperature by the method of natural ventilation could not be satisfied the requirements of environment temperature for growing strawberry.
Figure 8 indicated that, under the working condition D, the average temperature in the greenhouse strawberry growing zone decreased with the increasing of inlet size, but the gradient of the temperature reduction was decreased.
Fig.8 Average temperature in D condition Fig.9 Average wind velocity in D condition Conclusion and recommendation The conclusion was given by the comparison between the experimental data in the wording condition F0 and the numerical simulations of indoor temperature filed and velocity field of the strawberry greenhouse as following: (1)The results of numerical simulation indicated that, the temperature stratification was appeared obviously near the “trickle film” in the setting working conditions in this study.
In the setting conditions of this study, 1) the inhomogeneity of the temperature distribution in strawberry growing zone was decreased with the increasing of inlet size opening, and the average temperature of the strawberry growing zone in the greenhouse also decreased, but the gradient of temperature reduction was dropped gradually.
(5)Through the contrast analysis of the results of the numerical simulation with the relative experimental data in the working condition F0, the errors were in the acceptable range, which helped to prove the accuracy and feasibility of the mathematical model and numerical simulation method used in this study of prediction and analysis the thermal environment of the indoor strawberry greenhouse with the method of natural ventilation.

Treatment causes some changes in the properties of the substrate such as a reduction of the % water uptake (up to 15%) as well as an increase in the elastic modulus (up to 10%). 1.
The addition of inorganic nanoparticles into silica matrix seems to contribute to the reduction of shrinkage and cracking after solvent evaporation [8-10].
The smaller increase in mass of RH, shows that the particular stone has less absorptive capacity in PMC, which also agrees with the data of % weight gain during application.
On the other hand, the rate of the water uptake for RH is less affected by the treatment where the % reduction ranges at 3-4%.
The results also showed a reduction in the average pore radius, mainly in RH, where in some cases the average pore radius was reduced from ~30 to ~8 microns.

It can be seen from this data that in general the theoretical values correspond well with the experimental results.
However the biggest discrepancy between the data sets is for the second mode.
It can also be seen from the data that the riveted joint loss factors are generally lower than those from the bolted joint.
The loss factors for the noncritical modes (3, 4, 5, 6, 8, 10) correlate well with the previous data shown in Fig. 5.
The general trend for the data is that the loss factors reduce for the higher modes.

For monitoring, real-time data were acquired by the NExT and the ERA.
This monitoring system using the EDR reduces the time of measuring and the number of data.
Then, the ERA is applied to this data, obtaining system characteristic parameters.
The data acquisition system was set up to measure CPS and coherence function.
Data acquisition system was used HP VXI 1432.

Data on daylight, ambient, and container thermal behaviour A, B and C are collected and compared with the data from the meteorological station in the district.
Thermal data aquisition Each container unit is equipped with an identical independent measuring system that collects ambient temperature and humidity data at a 10-minute interval.
Data are recorded at 10-minute intervals.
The data collected from independent devices are progressively evaluated in a four-step sequence, where filtering by relevance, sorting per circumstances, and data comparison is gradually performed.
Thermal data evaluation Data collected from independent devices are thereupon progressively evaluated in a multi-step sequence.
