The subject matter of the article represents summarized findings of the variance analysis of the
fractional factorial experiment (the Latin Matrix). The items analyzed collectively by the coauthors
include the discharge current, the pressure of the orifice gas, or the air, and the period of exposure to
the direct current of the glow discharge. The properties analyzed by the coauthors include the water
absorption capacity, the wettability, and the capillary rise of the repair vlieseline. The discharge current
range was 20-100 mA, the pressure range was 50-200 Pa and the treatment time range was
15-120. The experiment was conducted according to the Latin matrix method, and the analysis of
variance (ANOVA) was used to check the influence of the discharge current, pressure and the treatment
time onto the hydrophilic properties of the material. The coauthors have demonstrated that the
discharge parameters are an insignificant factor in comparison to the exposure period.

The authors analyze the role of self-contained heat sources in the process of replacement of organic fuel by nuclear fuel. The authors also consider alternative sources of heat supply and practical implementation of systems of nuclear heat supply.The authors argue that various technologies require a wide range of steam capacities (0.1...10 MPA) and that the distribution of its quantity is uneven: up to 60 % of steam consumed at the pressure of 0.8...1.4 MPa and up to 25 % — t the pressure of 0.5...0.8 MPa.The authors address one of major challenges of the energy consumption market — reduction of the share of fossil fuels in the fuel and energy mix of Russia. Fossil fuels may be replaced by the nuclear power if atomic sources are used not only in the production of electricity and heat supplies for end users, but also as sources of thermal power for industrial purposes.Generation of heat for industrial purposes is more complicated, particularly when steam is required as a heat carrier. One of solutions under consideration is the use of high-temperature water to extract steam for heating purposes.

The article covers the concepts, definitions and correlations of parameters of worn surfaces
within the coordinate system of relative pressures and convergences of interacting elements of
construction machines.
The authors provide their findings based on the research of microtopographic and tribological
engineering parameters of scoop hinges of construction drags and fused crushing plates of jaw
crushers. As for the drag hinges, the friction pair is to include steel 110Г1ZL and X-5 padding that
demonstrates high resistance to friction (=1.04) and low temperature of frictional heating (ƒ= 90
°C). Mobile plates of jaw crushers need electrodes VSN-9 and TsN-16 for padding purposes, as they
demonstrate the biggest frictional fatigue values (= 2.76 and 2.62, respectively) and insignificant
temperature of heating of friction surfaces (9.4 and 4.9 °C). Electrodes TsN-16, T-590 and KBKh-45
are recommended for fixed plates.
Microtopographic parameters of worn friction surfaces are used to analyze the main tribological
engineering parameters of operating elements and joints of construction machines and items of
equipment.
