Summary: The mechanism of appearance of acoustic error of inercial'nogo touch-control is exposed with float zhidkostaticheskim podvesom. Built calculation charts of resilient co-operation of the mechanical systems of multiaggregate structure of navigation equipment of hypersound technologies. An analysis is conducted and nature of the diffraction phenomena of penetrating acoustic radiation is found out on the airborne equipment of flying wares in exploitation terms. Two modes are considered is a general case of influence of sound-wave in reverberation space of acoustic environment and critical case of display of features of resonant type as a wave coinciding (geometrical resonance).
Keywords: hypersonic technology, inertial sensors, penetrating acoustic radiation impedance, phase error.
Abstract. Independent power production is widely used in the US and Europe and acquires distribution in connection with the development of renewable energy sources. At this stage of technology electricity generation using wind, solar and biomass with few exceptions, is unprofitable and subsidized by the state budget. The prospect of decentralized power production involves usage of waste gasification for generating gas and using gas as a fuel for internal combustion engines, which are used as drive for power generators.
Keywords: electricity, renewable sources, biomass, waste, gasification.
Summary: We have investigated the safety and quality of the spreads, which are realized in the Ukrainian market and found that some spreads are imitations and can be dangerous for human health.
Key words: safety, quality, combined fatty products, trans-isomers, microbiological indexes.

Abstract: This article discusses the development of adaptive, сross-browser web pages for devices with different screen resolution and using different browsers to display. For the code organization, to do less error and to enhance architecture project is using technologies such as preprocessor SASS and the streaming build system Gulp.js. The publication describes the reasons for choosing these technologies and using them in project to write high quality, optimized, how don`t duplicate code and spread errors when the project will be expand.
Keywords: web development, mark-up, using preprocessor, streaming build system, code optimization.
Summary: The example of reconstruction works execution for damaged reinforced concrete constructions using advanced materials and technologies is given. The importance of adherence to building regulations ensuring workmanship quality is emphasized.
Key words: repair of reinforced concrete constructions, building regulations, repair aggregates, workmanship.
Summary: Possibility of technical realization of disguise of fire weapons of the field fortification of open type is analysed from an airspionage. It is well-proven that secrecy and limit notability of military equipment can be provided by the artificial forming of surface of obstacle to query facilities as zones of каустики in liquid part of the cylindrical module camouflage to the tunnel. Outlined terms of forming of surface of protecting from a location ray at resonant level of wave coincidence and considerable wave size of shell of the module.
Keywords: wave size, абберация, zone of каустики, wave coincidence.
Summary: Subject of interstellar flights remains actual taking into account limitedness of the terrestrial resources, overpopulation of the planet, and demographic, sociopolitical and ecological problems at the planet. A constructive solution is submitted of the construction of a spacecraft moving with acceleration resting upon electromagnetic fields of the Solar system and the Galaxy. Calculation of the current intensity within the circuit and charge value at the object's useful surface necessary for the achievement of acceleration equal to at arbitrary direction in the space is conducted.
Keywords: electromagnetic fields of the Galaxy; magnetic levitation; spacecraft; Lorentz force; dependence of mass on velocity; redistribution of charges by surface.
Summary: Basing on the results of industrial experiments, carried out on the real pipeline, the patterns of flowrate changes during unsteady processes, caused by a changing the number of working units at oil pumping stations, were established. The method of determining mean oil flowrate against time and length was developed, which allows to specify the flow capacity of the oil pipeline during unsteady processes in operation.
Keywords: unsteady hydrodynamic process, oil flowrate, flow capacity, pumping units start.
