This publication examines the relationship between the structure of molecules of complexing (descriptors of electronic structure), which are used as inhibitors of hydrogen embrittlement of the steel grade St3, and the content of absorbed hydrogen in model samples-plates made of the above steel. The form of expression of this relationship is the correlation coefficient (CC) by Pearson

substantiated in the article. The existing services that
provide similar services were analyzed, their
shortcomings and advantages of the basic principles of
operation were identified and analyzed. Functional of
own service was disclosed in comparison to existing
ones. The variants to benefit drivers and passengers
were offered
The article considers the procedure and peculiarities of formation and submission information about transac-tions between related parties for the purposes of tax control. The authors proposed a mechanism to take account of emerging objects and the characteristic of procedure and tax policy in submitting the report about the controlled transactions
The reliability of work of the technical systems significantly influences the technological losses of manufacture process. During the counting the availability ratio of the technical system it is recommended to take into the consideration implicit as well as evident breakdowns of all separate components of the whole object. There is a formula for counting technological losses depending on the availability ratio of technical object. Similar formulas for counting losses proceeding of atmosphere and water resources pollution, pollution of soils with hard matters are obtained. Introduced identities bring together reliability of the technical systems and separate components of ecological losses
The article is devoted to the development of energy-saving sowing section of bread-stuff seeding
machines of direct sowing, methods of theoretical and experimental determination of drag-out resistance of combined plow are casted.
In this article, we have presented the results based on the experimental research of effort of giving and effort of cutting on a band-saw machine for new and already worn-out saws
In the article we have studied 55 aboriginal varieties,
collected in the North Caucasus. We have described
allelic diversity and identified four haplotypes. All the
populations were closely related while being examined
using a factor of Nei's genetic distance (Dn), with the
exception of indigenous varieties of Armenia.
Maximum differences have been found between the
Uzbek population and Astrakhan, Turkmenian,
Armenian populations. The most genetically rich were
the population of Don area and Krasnodar region
This work presents main kinds of colourants and methods of painting wood particles. Based on wood structure analysis, it was revealed that hard wood, possessing tracheides and vessels as conducting elements, have the optimal capacity for coloration, in comparison with coniferous trees. A methodology was developed of cloning wooden particles, in the form of chips, with forced immersion in order to obtain established parameters of saturation and brightness. The experiments were conducted with chips of 15-50 mm long, 5-20 mm wide and 3-7 mm thick. The composition of colouring agent included water, acetic acid, and water-emulsion colourants of different types and colours (№1 – colour code (red, yellow, and brown) №2 – colorant (lilac and orange) and №3 – paint). Experience has shown the needed concentration of liquors and mass percentage of compounding ingredients. The research was undertaken to study concentration dependence on the time of allowance and saturation. In consequence of colouring experimental batches of chips, a painting saturation of 4-9 points was obtained at the allowance of 120 and 140 seconds. Dependence of brightness from solubility was determined, with high correlation between given parameters on Pearson Criteria (more than 0.9). Comparative analysis made it possible to discover that the better colouring of particles is created with the red paint. In this case maximum colouring effect is achieved with liquor of water-emulsion paint. Subsequent to the experimental results, a design of installation for colouring wooden particles was developed and patented
