From the pilot section of the gas pipeline, after ten years of operation, specimen-witnesses were seized. The gas pipeline consists of reinforced polyethylene pipes with an average adhesive reinforcing layer. The results of mechanical tests of model samples are given in the article. Investigations of the deformation-strength properties of the witness specimens show a decrease in the temperature of the viscous-brittle transition to -15 ° C. These results indicate a deterioration in the adhesion between the outer layers of PE80 and the middle technological layer. Good adhesion led to the emergence and development of a fragile crack. Stability tests at constant pressure showed satisfactory results, not a single sample collapsed. According to the research data, the reinforced polyethylene pipe did not deteriorate its deformation-strength properties for ten years of operation of the gas pipeline under pressure.

It is noted that traditional technologies do not provide removal of organic substances from water, and primary chlorination leads to the formation of highly toxic halogen organic compounds in it. The perspective of using membrane technologies for water purification of surface sources based on: micro-, ultra- and nanofiltration, reverse osmosis, allowing to solve the set task is shown. This was realized during the purification of the Don and Moscow rivers with the use of the biosorption-membrane method, which involves sorption on activated charcoal, biological oxidation of organic substances and filtration through the membrane. The obtained results give the basis for wide application of this method in treatment plants of small settlements, which is especially important for the south of the country, in particular, the Rostov region and the Republic of Kalmykia.

The article shows that for more effective planning of forest harvesting operations logging companies require a tool that would assess the amount of industrial bucked wood produced on a сutting area by size, by groups and by timber species. It is so because data available on material and monetary value cut markedly differ from the actual results of the complex harvesting machines working, which are reflected in the summary statement of wood assortments acceptance.

Providing the claimed performance characteristics of the absorber throughout its life is the most important task that ensures the correct operation of the coupler. Increasing requirements for increasing the speed of movement and the volume of freight traffic make it urgent to increase the reliability of the absorbing apparatus by improving the design of its components and components (housing, friction plates, wedge, etc.).

The crosstalk level increases with increasing degree of circuit integration. At the same time, requirements to their noise immunity increase. The increase in the amplitude of the pulse signals is a simple and effective method to improve noise immunity. The article discusses the synchronization system with the global distribution of low-voltage clock signal and a local increase in the amplitude using drivers with increasing voltage. Proposed technical solutions allow to set the amplitude of the clock signal individually for each functional unit.

The work is dedicated to the method of threshold separation of digital data, based on the use of bit masks, and evaluated the possibility of its use in the divided transmission data. According to the data split transmission scheme the sender divides the original data into several parts which are independently transmitted via various communication channels, and the receiver reconstructs the original data from parts transmitted. The split transmission can be used to increase the speed of communication or its reliability, as well as to ensure the privacy of transmitted data due to the complication of the problem of interception of multiple communications channels. The requirements for the threshold methods of data sharing for their use in the split transmission are formulated the correspondence between the bit masks method and the advanced requirements is analyzed. An algorithm for using the bit masks method for transferring confidential information in a split transmission system is developed.
