POWER SOURCES OF OPERATION, CONTROL AND PROTECTION DEVICES
DescriptionCurrently operating in autonomous systems of power supply DC voltages power sources are secondary sources for operation devices, protection and control of generators, motors, stabilizers and inverters have relatively low operational performance. The work proposes to improve the weight and the size of power supplies to apply a high frequency link in their designs. We provide structural designs and the peculiarities of operation of secondary power sources with a high frequency link. This article discusses the fundamental electrical circuits of pulse regulators, converters based on resonant inverters and transformers with rotating magnetic field. The use of resonant inverters in power sources will significantly improve their weight and overall dimensions. In addition, the use of secondary sources of supply for transformers with rotating magnetic field will simplify their design and reduce the level of electromagnetic interference generated by semiconductor devices. The features of operation of pulsed regulators and prospective structuralschematics converters discussed in the article, performed on resonant inverters and transformers with rotating magnetic field, will increase the effectiveness of pre-work on the development of secondary power sources with improved operational and technical characteristics for devices of operating, control and protection

06.00.00 Agricultural sciences
DescriptionThe article presents the data of 40-year-old variety-trial cultivation of hybrid black poplar and balsamic sections, as a result of which addressed issues of selection range of appropriate varieties, their cultivation technology, aspects of agrotechnology and protection against pests. At the same time, it absorbed and non-forest land reclamation funds, in particular sandy and shell, lowhumus, floodplain soils. As a result, the five-year variety trials found that under the conditions of the Eastern Azov on humus shell rock underlain by low-mineralized groundwater on accessible depth for roots (up to 150 cm), the most highly productive and are stable clones of Euro-American poplar: Brabantika-175, Sanrau-59, a Moshnyi-236 and 195 , Bahel, ZS-33 Vernirubens, 60001/1, Caroline-162. In terms of growth, they are superior to the local Canadian poplar and other varieties of poplars. Resistance to environmental and biological factors of the environment most highly productive species and varieties of poplars are much higher than the low productivity. Culture of poplar planting might create unrooted plants directly on the silvicultural area, which reduces the cost of rooting plants at the nursery, their digging and transportation and provides a high survival rate. Culture of poplar are used for the afforestation of poor sandy forest-steppe zone arrays, often introduced as the main breed at shelterbelt afforestation

TO THE 100TH ANNIVERSARY OF THE GREAT OCTOBER REVOLUTION: THIS ETERNAL LAND QUESTION ...
DescriptionThe relevance of the causes, results and consequences study of the October Revolution in Russia is shown. The problems of modern land relations are formulated. It is concluded that one of the main reasons for the October Revolution was the unresolved land issue, which remains unresolved during the modern economic reform. The centennial anniversary of the Great Russian Revolution is an occasion to comprehend the whole complexity of land relations, to see the solution of modern land problems in the historical retrospect. The goals and objectives are formulated, the prerequisites, main provisions and results of the Russian reforms of 1861, including the Stolypin reform, are considered, the historical stages in the formation of the land property institute in Russia are shown. The organizational and economic mechanism for implementing the basic land reforms is analyzed. The mechanism included the elaboration of the main redemption operation plan provisions, the resettlement policy in newly developed areas, the activities of the Peasant Land Bank, land management. The main socio-economic results of the reforms are given. It is concluded that the Russian reforms were carried out by decision "from above," they were not completely consistent, the issue of the land ownership was not finally resolved. The reasons for the Russian peasantry active participation in the Great October Revolution are formulated: the centuries-old peasants lack of rights and oppression, their personal and economic dependence on the landlord, serfdom, lack of property, heavy redemption of the 1861 reform obligations and delay of the Stolypin reform; and on the other hand - promised will and land by the Bolsheviks. The views on the revolution results belonging to well-known economists, historians, writers are given. To create a great Russia, the expediency of country's socio-economic development in the only evolutionary way is justified, based on a clearly developed strategy

TO THE 100TH ANNIVERSARY OF N. I. VAVILOV’S RULE ON HOMOLOGICAL SERIES IN HEREDITARY VARIABILITY
06.01.05 Selection and seed production of agricultural plants (agricultural sciences)
Description100 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

TO THE ANALYSIS OF DEVELOPMENT OF PEASANT AND PERSONAL FARMS OF THE POPULATION
DescriptionSmall agrarian and personal peasant farms present an important segment of agricultural production along with other subjects. Their role is becoming more prominent with the increasing of their own production potential. Nevertheless, their resource base remains very weak, the basic means of production are worn out, and many of them are unable to improve technical equipment. In this segment, leasing options are limited, there are problems in logistics management, and small entities do not have market power in the market of production resources and in products marketing. The lack of collateral generates high cost lending and permanent bankruptcy. On the other hand, it is noted that small entities have a large diversity of organizational and legal forms, an informal control system high interchangeability of production functions, they combine the status of the owner and the manager. They significantly reduce the social tension in rural areas; they play a significant role in import substitution. Characteristic features of small agricultural farms (SAF) are high autonomy, independence, self-protection from environmental factors. They spend little money on creating jobs, have low fixed costs and independently overcome the difficulties. However, an underdeveloped industrial infrastructure of small business hinders the improvement of the technological level. They work with constant external interference, which reduces their production efficiency and market competitiveness. All of them highly depend on local production conditions, capacity of territorial markets. Low level of cooperation of participants SAF significantly limits the number of sales channels, increases the volatility realization. The analysis showed a high need for realization of the revealed reserves of efficiency growth
