Up to 90 % of hydrogen sulfide found in the water and gas-air environment of biosphere objects was formed microbiologically as a result of bacterial sulfate reduction (reduction of sulfur-containing compounds, mainly sulfates) [1, 3].
Using potentiometric equipment, the oxidation-reduction potential of pore moisture (Eh) on the wetted surface of concrete and the pH of concrete were determined.
Identification of mineral phases was carried out according to standard tabular data.
As can be seen from the presented data, all concrete samples were subjected to acid aggression: the pH of the concrete samples of the above-water part of the water management facilities was significantly lower than the pH of the control sample.
The content of sulfate-containing minerals in the tested concrete samples (according to X-ray phase analysis data) – gypsum dihydrate; – anhydrous sulfosilicate: 1 – sewer collector, 2 – primary sump, 3 – oil trap , 4 – control It can be noted that the concentration of sulfate-containing minerals is the highest in the first sample (the most affected by corrosion).

Integrated circuit miniaturization is driven by the demand of increased speed and low power consumption, required for future computing paradigms like cognitive computing and massive data processing.
A comparison with existing experimental data proves the outlined criteria correct without exception. 2.
Sub-micrometer size metallic wires Size reduction and speed maximization have been the major drive for the steadily growing high integration density of semiconductor devices on computer chips.
Many previous electromigration data with pure metals and dilute alloys of Al, Cu, Ag, and others point toward a superior performance of single crystalline interconnects [5].
The electron density n(r) near the surface of the jellium experiences a steep, although not abrupt reduction toward an embedded vacancy.

However, there is no data on the dissipation of the parameters of technological loads and limitations when considering the strength of equipment on the base of the probabilistic approach.
The main sources of danger for rolling equipment are rolling routes of billets with maximum dimensions and reductions, as well as with high deformation resistance due to either the basic mechanical properties of titanium alloys or a low deformation temperature in combination with preliminary hardening.
Consequently, it is necessary to relate the levels of technological loads to specific rolling routes and thereby identify the most stressful reduction patterns in terms of equipment loading.
In addition, at this stage, it is necessary to correct the results of the failure risk analysis, taking into account the statistical data accumulated at the enterprise, recorded in the repair logs for each of the rolling stands.

As authors[8] conclude, two conditions need to be considered when photocatalysts are coated onto supports: a) good adherence to the support; b) non reduction of a catalyst activity because of the coating process.
However, in all experiments with TCPG under sunlight there was blue shift of the absorption band, for example Fig. 2, constructed using the data of the previous Figure, presents hypsochromic effects for three wavelength peaks in the course of elapsed photo irradiation time.
Data taken from “Solar light + TCPG” curve of Fig. 1 The effect of initial TiO concentration (Fig. 3) revealed the optimum loading was 25 g/L.
Data of Fig. 4 photocatalytic degradation of MB followed pseudo-first-order kinetics (Fig. 4).
Reduction of photocatalyst’s activity during 15 identical runs with the same 25 g/L of TCPG TCPG photocatalytic activity reduction rates were measured by repeated experiments with the same 25 g/L of coated granules.

With the further reduction of x, the Y2O3 diffraction peaks appeared and became increasingly apparent in the XRD patterns, while the BiYO3 diffraction peaks became relatively smaller.
With a reduction of x, BixY(2-x)O3 exhibited a blue shift from Bi1.8Y0.2O3.
The band gaps determined from the equation using the data in the UV-vis spectra of BixY(2-x)O3 (x=2.0, 1.8, 1.6, 1.4, 1.2, 1.0, 0.8, 0.6, 0.4, 0.2) calcined at 750 oC for 10 h are 2.80, 2.42, 2.47, 2.48, 2.50, 2.64, 2.64, 2,68, 2.83, 3.12 eV, respectively.
The data indicates that there are at least three kinds of binding oxygen, namely, a) oxygen in the lattice (O2-) (528.8, 529.1, 529.2 eV) [13], b) oxygen in the hydroxyl group on the photocatalysts’ surface (-OH) (531.4, 531.3, 530.8 eV) [14], and c) oxygen absorbed on the surface (O-) (533.4, 533.0 533.1 eV) [14].
It can be seen from the data obtained that the photocatalytic activities of BixY(2-x)O3 are closely related to the absorbance, band gaps, and the proportions of Bi and Y.

Error bars for the hardness represent standard deviations in the respective data sets, which included at least 50 indentations per processing condition (Table 2).
The plastic strain magnitudes achieved for the chips here appear to saturate at values of a bout 2.1 and exhibited a reduction with increasing tool velocity, which was more significantly for the 20˚- than the 0˚-angle tool.
Notably, room temperature cold-rolling reductions to strains equivalent to those imparted here have been shown to result in ~30-50vol.% SIM for 316L [16].

Due to the limited field prototype observation data, the dynamic model failure tests become more effective means than numerical analysis to investigate nonlinear dynamic response and failure mechanisms of concrete dam.
To satisfy the growing demand for electricity and increasing pressure for carbon emission reduction, some high dam projects have been established and will be built in this seismically active area.
The stress-strain data for a typical uniaxial compressive test is shown in Fig. 1.
Generally speaking, the shaking table is composed of following: A movable table, a loading system with several degrees of freedom, a system generating pressurized hydraulic oil, a servo-control system, a driving system, a reaction base mat, a system of acquisition and data processing.
When gravity plays a dominant role for a structure, such as in gravity dams, the most essential one is the scaling of gravity which must be inversely proportional to the reduction in size from prototype to model to keep the stresses equal, model test can only be performed in centrifuges.

Static properties of steel C45 under tensile loading are as follows: yield limit Re = 460 MPa, tensile strength Rm = 682 MPa, resilience module E = 215000 MPa, elongation A5 = 24,3 % and reduction of area Z = 44,3 %.
ANALYSIS OF TESTS AND CONCLUSIONS Data from table 1 has been presented in fig.1 in a graphic form in order to facilitate an analysis of the results.
The above discussed data can be found in the auxiliary table in figure 2.
Data presented in table 1 and figure 2 concerning ratio λ0/λc shows a significant spread of the tests results depending on the series of parameters of a given stress program.
Omitting the steps of stress amplitude below 0,4 Sf(-1) results in significant shortening of the time necessary to perform fatigue tests as well as reduction of costs.

The flow stress was calculated from the FE data – performing a virtual measurement – using Eq. 3: (3) where F is the force at a given state.
These data show that the requirement (a) of the Watts-Ford geometry is not met during the whole test, the requirement (b) is also not met at the beginning, but by the end of measurement the w/s ratio may get into the range of 2 and 4.
The force – height reduction diagrams are shown in Fig. 8.
The grooves on the contacting surfaces kept the high viscosity lubricant (beeswax) during the test, therefore significant height reduction was possible without barreling.
