INTERACTIONS OF GOLD, SILVER AND MAGNESIUM NANOPARTICLES WITH PLANTS
DescriptionThe review examines the recent years’ data pertaining to the interaction of plants with nanoparticles of noble metals (gold and silver) and with nanoparticles of magnesium as an element that has a central role in the organization of the cellular protein-synthesizing apparatus. Information is presented about the effect of gold and silver nanoparticles on plants and on possible nanoparticle phytotoxicity. It is shown that magnesium nanoparticles, as well as those of noble metals, produce various effects on the growth and productivity of plants, enabling the arsenal of biologically active substances to be expanded. Analysis is made of the involvement of magnesium nanoparticles in cryobiological reaction of the regular breakdown of plant RNA under conditions of ultra low temperatures, which is important not only for the further developments of views of the origin of life ob Earth but also for the purposes of designing new markers for the analysis of the biological peculiarities of agricultural crops on the basis of studies of magnesium in the long-lived RNA of their mature seeds. The presented critical analysis of the literature data, which are often incomplete and contradictory, suggest that a coordinated research program is needed that would detect correlation between particle parameters, experimental design, and observed biological effects

SPECIFICITY OF TRILON B INFLUENCE ON THE GERMINATION OF SEEDS OF VARIETIES OF WINTER BARLEY
DescriptionThe problem of increasing resistance of winter barley to adverse conditions of winter is the most problem in the selection area of this crop. The main component of this complex trait is the frost resistance. Laboratory methods of assessment of frost resistance are important for breeding of winter barley. These methods can effectively replace more costly method of direct freezing in the freezers. Magnesium cations (Mg++) are essential components of the protein-synthesizing system of germinating seeds. Magnesium cations determine the stability and translational activity of mRNA and rRNA. Trilon B is usually used for in vitro banding of magnesium cations in area of biochemistry of the nucleic acids. It was very interesting to verify the Trilon B influence to seed germination of winter barley varieties by experiment. Experiments showed: actinomycin D – the inhibitor of RNA synthesis – didn’t show varieties specific effect to seed growth of winter barley, while Trilon B had a varieties specific impact to length coleoptiles and roots. Research was carried out on etiolated seedlings at temperatures from 22 to 28oC, and different concentrations of Trilon B - 1,6×10-3М, 2,4×10-3М and 3,2×10-3М. The roots of 3-days old seedlings were more sensitive to Trilon B influence. It is shown the varieties of Russian origin were naturally reacted to Trilon B: the higher the frost resistance of variety, the more resistant variety to the action of various concentrations of Trilon B at different temperatures. The most optimum concentration was 3,2 × 10-3М at 22-25oC. Varieties by foreign origin deviated from this pattern. It is interesting to research the genetic essence of these differences. It will be helpful for optimization of varieties differentiation conditions to create a laboratory method of estimate of frost resistance of winter barley. The new method will be most efficient compared the direct freezing method

INFLUENCE OF COMPLEX COMPOSTS ON DEVELOPMENT OF LIVING ORGANISMS IN TOP LAYERS OF ORDINARY CHERNOZEM
DescriptionComplex compost, which is formed in the process of unification of organic and mineral colloids, the formation of new cycles of nutrients, increasing the enzymatic activity of organic matter and respiration of living organisms, the formation of gaseous compounds, increase of ecological niches and land reclamation is a new direction in practical ecology, agriculture and soil science. This line determines of creation and use of complex mixtures of different wastes household, industrial and agricultural production for enrichment soil of organic and mineral dispersed and colloidal systems and improving their physical, chemical and biological and ecological functions. Formation of complex of compost is provided by the enrichment of substrate of organic matter, comprehensive set of mineral substances and their mixed colloidal composition. Microbial communities are determined by the level of transformation of organic matter and activity of life support system and the variety of living species. Entering into the top layer of soil of complex compost contributes to the development and expansion of ecological niches. At the complex compost it is very active increases the number of actinomycetes, especially representatives of the genus Streptomyces, the population of which are accumulated in the top layer of soil in the summer. Actinomycetes series of Cinereus were encountered most often in the soil after introduction of complex compost, Violaceus and Aureus were allocated less

RESOURCE POTENTIAL IN LUTEOLIN-7- GLYCOSIDE VERONICA INCANA (SCROPHULARIACEAE) IN CENTRAL YAKUTIA
DescriptionThe article reveals luteolin-7-glucoside accumulation in the overground part of Veronica incana L. It assesses resource potential of V. incana depending on the phytocenotic conditions of coenopopulations growing in Central Yakutia. Collection of the material was carried out during V. incana flowering in 7 coenopopulations and in the collection of the Yakut Botanical Garden. Analysis of flavonoids content was performed by HPLC method. The high levels of flavonoids content in the biomass of generative plants marked in coenopopulations that are in optimal conditions, and the lowest - in coenopopulations experiencing strong anthropogenic influence. In addition, one of the factors reducing the content of flavonoids in plants is low light intensity in habitat. The highest resource potential on the luteolin-7- glucoside observed in biomass V. incana, growing in fescue grassland steppe and culture

TO THE QUESTION OF MATHEMATICAL METHODS DEVELOPMENT OF CONTROLLING
01.00.00 Physical-mathematical sciences
DescriptionOn the basis of the objective analysis it must be noted that in the arsenal of managers, especially foreign ones, there is practically no fundamentally new methods and tools of controlling. So says the executive director of Russian Association of Controllers prof. S. G. Falco. However, promising mathematical and instrumental methods of controlling actively developed in our country. It is necessary to implement them. For example, managers should be used techniques which discussed in the book by Orlov AI, Lutsenko EV, Loikaw VI "Advanced mathematical and instrumental methods of controlling" (2015). These methods are based on the modern development of mathematics as a whole - on the system interval fuzzy math (see the same named book by Orlov AI and Lutsenko EV, 2014). Considered methods are developed in accordance with the new paradigm of mathematical methods of research. It includes new paradigms of applied statistics, mathematical statistics, mathematical methods of economics, methods of analysis of statistical and expert data in management and control. In the XXI century there were more than 10 books issued, developed in accordance with the new paradigm of mathematical methods of research. The systems approach to solving specific applications often requires going beyond the economy. Very important are the procedures for the introduction of innovative methods and tools. In this article we consider the above research results in their interconnection

DescriptionThe relationship of Mathematical Statistics (wider - Mathematical methods of research) and history is multifaceted. In our opinion, the history of mathematical statistics is an integral part of this mathematical discipline. We have given a review of our works on the history of statistical methods. The role of mathematical statistics for the history is very important. In this article, we restrict ourselves to the questions of chronology. For centuries, the chronology is considered as a part of applied mathematics. The main problem is that the whole "common" concept of the Russian and the World history as a whole presented in textbooks was faked by the opponents of Russia after the collapse of the global Empire (Russian kingdom) in the early 17th century - 400 years ago. The stories about historical events are the information weapon. It was used by the new rulers to suppress the resistance of the vanquished. A new mathematical and statistical chronology of general and Russian history, which was built by a scientific team led by Academician Fomenko, has been helpful for the discussion about the current economic and political problems of relations between Russia and the West in the XXI century. In our opinion, the new chronology of the World and Russian history should be one of the foundations of state-patriotic ideology and deriving practical solutions. The purpose of this article is to give the initial idea of the new chronology from this point of view

PARTICLE DYNAMICS IN METRICS WITH LOGARITHMIC POTENTIAL
01.00.00 Physical-mathematical sciences
DescriptionParticle dynamics in metrics with logarithmic potential The work considers the problem of modeling the motion of particles in a unified field theory to 6D, in theory, supergravity in the 112D and metric galaxies. We have investigated a centrally symmetric metric in the 112-dimensional Riemannian space, which depends on the radial coordinate, time, and 110 angles. We present a system of equations describing the angular movement on a hypersphere of any dimension N. It is shown that the motion on the hypersphere depends on the 2 (N-1) of singular points. We have installed general nature of relativistic motion on a hypersphere when it is displayed on the plane and in three-dimensional space. It is shown that the motion determined by the reflection from the singular points that of motion on the plane in some cases leads to thickening of the trajectories in the neighborhood of sides of the rectangle. The 6D investigated metric describing the case of motion with two centers of symmetry. It is shown that in such a metric exists a class of exact solutions, logarithmically dependent on the gravity centers of origin. It is found that in this system there is a motion with condensation paths around the sides of the rectangle, due to scattering of test particles gravity sources. We set the general nature of angular motion on a hypersphere and radial movements in 6D in the metric of a logarithmic potential. It is proved that similar solutions with logarithmic potential exist in galaxies metric in the metric of Einstein's theory of gravity. The article also describes the connection of the solutions to the nonlinear electrodynamics, and with a theory of quark interactions and Yang-Mills theory

LOGARITHMIC LAW FOR DYNAMICAL SYSTEMS FROM QUARKS TO GALAXIES
01.00.00 Physical-mathematical sciences
DescriptionThe article discusses various examples of dynamical systems in which the motion is determined by the logarithmic law - quark systems, hydrodynamic systems, galaxies. Set the general nature of angular motion on a hypersphere in a space of arbitrary dimension and radial movement 6D in the metric of a logarithmic potential. We investigate the 6D metric describing the case of motion with two centers of symmetry. It is shown that in such a metric exists a class of exact solutions, logarithmically dependent on the gravity center coordinates. It was established that in spiral galaxies the orbital motion is due to the logarithmic potential, which is the exact solution of the field equations of Einstein's theory of gravity. The most well-known and widespread in nature case is turbulent flow over a smooth or rough surface, in which the mean velocity depends logarithmically on the distance from the wall. We derivate the logarithmic velocity profile in turbulent flow from the NavierStokes equations. An analogy of the logarithmic velocity profile and the logarithmic law in the case of erosion of materials under impacts been proposed. In electrodynamics, Ampere's law, which describes the interaction of current-carrying conductors, is a consequence of the logarithmic dependence of the vector potential of the distance from the conductor axis. There is, however, an alternative derivation of Ampere law of the Riemann hypothesis about the currents due to the motion of charges
