Metric describing the accelerated and rotating reference system in general relativity in the case of an arbitrary dependence of acceleration and angular velocity on time has been proposed. It is established that the curvature tensor in such metrics is zero, which corresponds to movement in the flat spaces. It is shown that the motion of test bodies in the metric accelerated and rotating reference system in general relativity is similarly to the classical motion in non-inertial reference frame. Consequently, there exist a metric in general relativity, in which the Coriolis theorem and classic velocity-addition formula are true. This means that classical mechanics is accurate rather than approximate model in general relativity. A theory of potential in non-inertial reference systems in general relativity is considered. The numerical model of wave propagation in non-inertial reference frames in the case when potential depending of one, two and three spatial dimensions has been developed. It is shown in numerical experiment that the acceleration of the reference system leads to retardation effects, as well as to a violation of the symmetry of the wave front, indicating that there is local change of wave speed
We investigate the hypothesis of a plurality of parallel and virtual worlds. It is assumed that sentient beings in each virtual world reach a stage of development that can create a virtual world to simulate the history of their own development. In this case, the virtual worlds are nested within each other, which put a severe restriction on the possible geometry of space-time. Discussed the draft geometry virtual worlds consistently displayed from one world to another. It is shown that in this case, the metric should be universal, depending only on the fundamental constants. There are examples of universal metrics obtained in Einstein's theory of gravitation and Yang-Mills theory
The article considers measuring scales as a tool for creating formal models of real objects and a tool for increasing the degree of formalization of these models to a level sufficient to implement them on computers.
It also describes the different types of measuring scales, allowing to create models of varying degrees of formalization; lists the types of transformation valid during the processing of empirical data obtained with scales of different types; develops the task of metriza-tion of the scales, i.e. conversion to the most formalized mind; it proposes 7 ways of metrization of all the types of scales, providing a joint comparable quantitative processing of heterogeneous factors measured in different units of measure due to the conversion of all scales to one universal unit of measurement in which the measurement number of information is selected. All of these methods of metrization have been implemented in the system-cognitive analysis and in the Eidos intellectual system

The article presents the results of the study of microbiological composition of biohumus and humic substances obtained by fermentation method according to the technology developed by the authors. The problem of processing livestock wastes is caused on the one hand by the occurrence of large volumes of them, and on the other hand by the addition of such important elements as nitrogen, phosphorus, potassium, etc., which can be used as bioelements. The goal of research was to develop a technology for the production of humic compounds from biohumus and to study the microbial communities that occur in them. Results of researches showed that for biohumus with high content of humic substances, bovine manure must be composted with chopped straw at the ratio of 8:1. Biocomposting of manure and crushed straw using the developed technology enables to obtain biohumus containing humic substances of 20 g/l. Among the physiological groups of biohumus microorganisms, the most numerous groups are aminoautotrophies and ammonifiers - 231.6×106 and 130.33×106 CFU/g, respectively. At the same time the grouping of cellulose-decomposer actinomycetes in biohumus was quite numerous and amounted to 0.93×103 CFU/g.
The article presents the results of the research of microflora composition of the leaf surface, the surface of fruit and flowers of Ribes nigrum, R. niveum, R . rubrum and Grossularia reclinata. The research was carried out in the seasonal dynamics from 2007 to 2014. The authors used the method of print for isolating microorganisms from plants. For convenience of calculations and contamination comparison of different environmental niches of plants the number of selected microorganisms was counted on the surface of 1 cm2. It was found out in the article that microorganisms on the surface of lamina are distributed unequally. The number of microorganisms on the bottom surface of the foliage in all periods turned out to be higher. The greatest number of microorganisms was recorded in autumn and reaches the highest value in October. The number of microorganisms on fruit surface increased with ripening and was the highest in July. The quantity on the flowers varies considerably throughout the flowering and is represented minimally compared to other plants niches. The study revealed species-specificity of microorganisms and the host plants. At the same time, long-term study of the microflora of plants belonging to one family made it possible to reveal species that are typical epiphytes

The article presents the results of studies on the effect of dietary supplements «Kumelaсt» and «Laсtumin» on the microflora of calves. Prepara-tions stimulated proliferation lactic acid microflora, which depressed proliferation of opportunistic or-ganisms, which prevents the calves from diarrhea
The obtained experimental data show that the incorporation of trace elements into the system of the sunflower crop has a positive impact on the mineral nutrition of plants, the number and quality of the crop. Foliar feeding of sunflower crops with micronutrients improves nutrition of plants with nitrogen, phosphorus and potassium, thus creating the preconditions for the formation of highly agrocenosis. The seed yield of sunflower increased by variants with application of micronutrients 1.2-3.5 t/ha or 4.4-12.9 percent. The greatest impact of treatment with boron and copper, exceeding the background option 3.1-3.5 t/ha or 11.5-12.9% respectively. The crop is least influenced by manganese and molybdenum. The examined elements positively influenced the structure of the sunflower crop. The greatest influence on the diameter of the basket, the number of seeds, weight of seeds in the basket, the weight of 1000 seeds was provided by the zinc and copper. Trace elements contributed to the improvement of quality indicators of sunflower. For husk content, the greatest positive effect was cobalt, zinc, manganese and copper, increasing the background option 10.1, 10.4, 10.5 and 10, and 6%, respectively, on the oil content of sunflower seeds had cobalt, copper and zinc. The oil content on these options amounted 55,0, with 55.1 and 55.2%, respectively, increasing this figure by 1.5 to 1.7 %. The acid number at variants with boron, manganese and zinc was the same with the background option and amounted to 1.8. The greatest influence on iodine number provided molybdenum, zinc and copper, which accounted for 170,5, 171,2 and 171,4, exceeding the background option 10.2 and 11.1
The soil by it physical and chemical properties is a
poly-dispersed heterogeneous multicomponent unique
environment for development of most microorganisms.
The soil is the richest natural substrate according
to microbial gene fund. Presence of plants and
animals in soil maintains it heterogeneous as environment
of soil microorganisms, which are main regulators
of natural gas composition of atmosphere of
Earth, including its macro- and micro-components
(including the main "greenhouse" gases - methane,
carbon dioxide, nitrous oxide). Recently, the elucidation
of these singularities of vital activity of soil organisms
has resulted in general conclusion - due to
them soil cover serves as a global bio-geo-chemical
membrane, through which the exchange of matter and
energy between pedosphere, lithosphere, atmosphere,
hydrosphere and main living inhabitants of Earth does
its work
