CRYSTALL SPACE METRIC

abstract 1271703072 issue 127 pp. 1010 – 1044 31.03.2017 ru 440
In the present article, we investigate the metric of the crystal space in the general theory of relativity and in the Yang-Mills theory. It is shown that the presence of a lattice of gravitational ether has observable macroscopic consequences. Earlier, the influence of the gravity of the celestial bodies of the solar system on the electrical conductivity, inductance, the rate of radioactive decay of atomic nuclei, on seismic activity, the magnetic field and the motion of the pole of our planet, and on the rate of biochemical reactions was established. In all cases, a similar behavior of the physicochemical characteristics of materials and processes is observed, depending on the universal parameters characterizing the seasonal variations of the gravitational field of the solar system. The relationship between lattice parameters and the properties of materials, elements, atomic nuclei, and elementary particles is discussed. Possible metrics of the crystal space are constructed: a metric that depends on the Weierstrass function, derived in the Yang-Mills theory and analogous metrics found in Einstein's theory. Such metrics, which have a central symmetry, can be used to justify the structure of elementary particles, the properties of atomic nuclei, atoms and matter. Periodic metrics are constructed that admit an electromagnetic field, as well as metrics associated with the assumed structure of the crystal space. These metrics are of particular interest, since the properties of the substance are related to the metric parameters. We proposed the model of electron beam as a streamer of preons

FEATURES OF THE ECOLOGY OF DRAINED SOILS OF DIFFERENT ECONOMIC USE

abstract 1471903016 issue 147 pp. 129 – 137 29.03.2019 ru 440
Slicesize soil is a kind of degradation of its changes. They are characterized by high density, hardness and other characteristics that reduce their effective fertility. Many authors have noted the progression of the process of fusion, which is associated with global warming, with over – compaction due to the unjustifiably frequent use of heavy equipment, irrigation-that is, with the direct impact of abiotic and anthropogenic factors on the pedosphere. Economic use – the strongest anthropogenic factor capable to bring the debugged mechanism of functioning of system out of action if not to observe scientifically-proved rules of agrotechnics. As a result of such intervention, the ecosystem is unable to independently neutralize negative deviations (consequences of anthropogenic impact) from the natural course of the processes of exchange of matter and energy. Therefore, the structure of agrocenoses should be as close as possible to the structure of natural biocenoses, namely: as fertilizers use more organic (manure, green fertilizers); to minimize the mechanical impact on the soil during its processing; to avoid such irrigation regime, which involves excessive soil moisture and its complete drying

TO THE 100TH ANNIVERSARY OF N. I. VAVILOV’S RULE ON HOMOLOGICAL SERIES IN HEREDITARY VARIABILITY

abstract 1602006002 issue 160 pp. 11 – 29 30.06.2020 ru 440
100 years ago, on June 4, 1920, 32-year-old Professor of the Saratov University Nikolai Ivanovich Vavilov (1887-1943) first reported at the III all-Russian selection Congress at the University of Saratov on his discovery of homological series in the study of parallelisms in the phenomena of hereditary variability by analogy with homological series of organic compounds. This discovery in genetics received the rank of law, the only one after the laws of G. Mendel. This major study was a further development of the genetic idea of C. Darwin on the origin of species. It showed the ways in which close species and genera of plants have a parallel formative process, because the crucial in the process of evolutionary development of living organisms – first of all, their genetic features. In cases where the development of a trait requires the joint and consistent action of many genes, the occurrence of homological series is inevitable, and this does not contradict the random variability of C. Darwin. In addition to its great genetic significance as a law of evolution, the law of homological series in hereditary variability is of great importance for botanists, plant breeders and breeders: it not only determines the place of each form in the plant world, but can also indicate to the breeder possible directions in his practical work. According to a number of geneticists and breeders, if G. Mendel discovered the rules of heredity, then N. I. Vavilov discovered the rules of variability

USE OF TERMS “ASU” AND “IS” IN AGRICULTURE FROM THE POINT OF VIEW OF INFORMATICS

abstract 1271703056 issue 127 pp. 803 – 823 31.03.2017 ru 439
The article deals with the issues of comparing the terms of ACS and IS with reference to automation in agriculture. In the technical literature, at conferences, in educational disciplines of higher education institutions, such terms as: information systems (IS), information technologies (IT), automated control systems (ACS) are often encountered. These terms are widely applied to the relevant objects in the subject areas under consideration. The area of coverage of the objects using these terms is very wide and in each case the definition of the applied term is either not specified at all considered self-explanatory, or the term is defined with various levels of detalization. In the latter case, the thoughtful researcher falls into some confusion or generally tries not to touch upon this question. In the article, on the basis of a review of known literary sources, it is shown which concepts are denoted by these terms when considering automation issues in agriculture. The subject of the study is the use of the terms IT, IS, ACS in works on automation in agriculture. The subject of the study is questions of comparison of the terms ACS and IS. The aim of the study is to indicate that automated IS is a more general concept than ACS

EFFECTIVENESS OF PROBIOTIC CULTURES AND THEIR CONSORTIUM ON THE MODELS OF EXPERIMENTAL INTESTINAL DYSBACTERIOSIS

abstract 1602006001 issue 160 pp. 1 – 10 30.06.2020 ru 439
The article demonstrates the results of therapeutic and preventive effectiveness of the use of lactic acid bacteria – Lactobacillus brevis and Lactobacillus parabuchneri in laboratory animals, in particular mice and rats. They were isolated from the gastrointestinal tract of a wild quail in experimental violation of the intestinal microbial background. Artificial imbalance of the intestinal microbiota of experimental animals was caused by the use of the antibiotic. As a result of tests it was established that the application of probiotic cultures improved microbial disorders of the gut, however, the use of their consortium in the probiotic promoted consistent clinical result characterized by an elevated level of representatives of the normal flora (lacto- and bifidobacteria) and reduction of the number of representatives of pathogenic and conditionally pathogenic microbiota, with subsequent achievement of a level characteristic of healthy animals

abstract 1321708083 issue 132 pp. 1066 – 1075 31.10.2017 ru 438
The article reflects modern condition of production of meat of cattle in Russia. We have analyzed the population dynamics of the cattle population and beef production and thee main problems that accompany the functioning of the beef cattle industry. We have given the measures of state support of the industry, to solve problems for which the Ministry of agriculture has developed a program to support the development of beef cattle. Considering prospects and possible risks of development of domestic the beef cattle industry, we have specified a need of such development of the branch; it has to be based, first of all, on implementation of large-scale projects on the basis of the competitive meat breeds of world level. On the basis of the findings we have identified the forecasts for the domestic producers, based on the current market dynamics. Solving the problem of providing the population with beef is possible at the expense of specialized meat cattle breeding. In order to improve economic efficiency of meat production of cattle we must not only find internal reserves and improve industrial relations economic relations, but the establishment of integration structures in the form of unions of agricultural enterprises, processing enterprises and marketing organizations, as well as large-scale economic and legislative support from the state

COLOR- SENSITIZED SOLAR ELEMENTS

abstract 1191605093 issue 119 pp. 1378 – 1389 31.05.2016 ru 437
Photovoltaic devices are a promising solution to the energy crisis, because they generate electricity directly from sunlight, without producing CO2. While color-sensitized batteries are the most studied element, mainly due to its low cost and high efficiency solar energy conversion into electricity. Until recently, the color-sensitized solar cells performance was less than 1%, however, the use of titanium dioxide as the anode material have greatly raised their efficiency. The advantages of titanium dioxide is primarily in the low cost, but its use provides high light capture efficiency, with external quantum efficiency (efficiency incident photon - charge), usually in the range of 60-90% using nanocrystal forms in comparison with
