It is described the charge-number of pulses-converter, which was successfully applied in the ”Program-apparatus complex for investigation of gamma- and X-rays radiations, generated by relativistic electrons in crystals” [1] at Kharkiv linear electron accelerators. This device is in the condition for high energy electron (positron) beam charge measurements with accuracy 2·10−10 C and current measurements in the range of 10−10...10−8 A.

Improving of livestock industry efficiency significantly depends on quality of feed preparation, as they are in cost structure of products are 30-60% of costs. Advanced technologies that allow to fully realize genetic potential of animals, due to the lack of necessary technical support have not become widespread. The experience of using intensive full-system technologies for livestock production shows that, along with reliable and balanced provision of farms with high quality feeds, traditional feeding systems are being improved, which are aimed at the development of economically efficient mechanized feed processing technologies and the preparation of full-range and balanced feed mixtures. Existing designs of feed mixers for cattle do not fully meet the zootechnical requirements for the preparation of multicomponent balanced complete feed mixtures, have high energy costs and high specific material consumption. Therefore, research aimed at developing working bodies for feed mixers, which will ensure the creation of a highly efficient feed base at low energy and material costs are of economic importance and is an urgent scientific task. In the article on the basis of the conducted researches the basic constructive-technological scheme of the effective single-shaft two-section mixer for realization of process of preparation of balanced mixes for cattle executed in the form of the horizontally located cylindrical case with the combined mixer consisting of section of screw tapes and flat blades (left and right) direction of inclination, the working surface of which is located at an angle of 45… 500 to the axis of the shaft and is equipped with radial fingers. The purpose of experimental research was to establish identification of developed mathematical models and adequacy of research results of proposed feed mixer and determine impact of basic parameters and modes of its operation on quality process. Аchieve this goal, mutual influence of simultaneous changes in speed of agitator shaft, width of flat blade angle of blade to axis of agitator shaft and duration of feed mixing on quality process: homogeneity of mixture and drive power of mixer shaft. Theoretical studies of the process of preparation of a balanced complete ration mixture confirmed the advantage of the developed design of the combined two-section mixer and increased the quality index (homogeneity of the mixture) to 98%

We investigate the dipole moments of the tau-neutrino at high-energy and high luminosity at linear electron–positron colliders, such as CLIC or ILC through the analysis of the reaction [Formula: see text] in the framework of the [Formula: see text] model. The limits on dipole moment were obtained for integrated luminosity of [Formula: see text] and mass ranging from 0.25 to 1.0 TeV. The estimated limits for the tau-neutrino magnetic and electric dipole moments at 95% of confidence level are [Formula: see text] and [Formula: see text] improved by 2–3 orders of magnitude compared to L3 and complement previous studies on the dipole moments.
