Description
The study of agronomy plants history, its distribution and use through image analysis and iconography have been presented. As an object of study, the image of wheat has been taken as the ancient culture of the world among agricultural plants. After many years, the illustrative series takes on a completely different meaning, namely, it becomes an independent resource of information. The analysis includes images of wheat in painting, sculpture, mosaic, tapestries, murals, botanical illustrations, stamps, porcelain and scientific drawings. In the work, we have made an attempt to analyze the images of wheat in the works of art in order to search for species diversity, directions of selection and genetic research, and also to present the morphological characteristics of culture. The method of analysis is a method of visual notes or sketches, which consists in comparing and searching information by image. The analysis is carried out on grounds: tall wheat, multiflorous forms of wheat, nonspreading, thickness of straw. The visual analysis of the images of wheat in works of art by the method of sketches made it possible to reveal the species diversity of culture along the ear, to see the ancient forms that were cultivated in the world before the "green revolution". The analysis included works of art from the 14th to the 21st century, the masters of painting in Italy, Germany, Russia, the Netherlands, France, the United States, and others

01.00.00 Physical-mathematical sciences
DescriptionThe article is dedicated to a numerical investigation of a plane problem of the oscillation amplitude of a buried source, depending on the frequency and motion speed in various isotropic media. Three types of the medium are considered: a two-layer package with a rigidly fixed base, a two-layer package with a mechanically free base, a half-space. The source, in the form of a stress jump simulating a rigid inclusion of small dimensions, moves in the interface plane at a constant speed. Homogeneous boundary value problems are considered in a moving coordinate system associated with a source. The solution method is based on the usage of integral Fourier transforms, the method of direct contour integration and algorithms for constructing symbols of Green's matrices. The method of direct contour integration significantly simplifies calculations in comparison with the traditional approaches to the calculation of Fourier integrals. We have presented calculations of nine amplitude-frequency and amplitude-velocity characteristics for different combinations of medium and source types, that give an exhaustive qualitative and quantitative description of the solutions for boundary value problems in a wide range of velocities and frequencies. Comparative analysis of calculations showed a primary influence of the type of an elastic medium on the investigated characteristics, as well as the large influence of the source type. Which, in turn, revealed some substantial connections between the boundary value problems with a moving source and the corresponding problems with a stationary source

Description
Currently, there is increasingly reduced number of the sites convenient for construction. In this regard there is a question of development of new territories, for various reasons which were earlier considered economically unprofitable or unsuitable for construction. Often, for construction in the mountain area it is necessary to carry out construction of objects in landslide territories. However, landslide processes constitute big health hazard and lives of people and also safety of buildings and constructions. The main objective of engineers when performing design and exploration work on landslide territories is the determination of stability of slopes and size of landslide pressure from soil and also identification of the most dangerous combination of loadings which can demand design and construction of a construction against landslide of landslide protection structures with significant load-bearing capacity. The research presented in article allows to define the most dangerous loads affecting the stability of the slope and also of the selection of a protective construction (against landslide). Dependences of change of landslide pressure and coefficient of stability of a slope are received from action of various loadings (both static, and dynamic)

PLANT HEIGHT AND LODGING RESISTANCE OF COLLECTION VARIETIES OF WINTER BARLEY
06.00.00 Agricultural sciences
DescriptionLodging resistant is a very important factor of limitation of the yield of barley. The yield of lodged crops may be decreased up to 50%. The quality of the yield also deteriorates which negatively affects brewery characteristics. The lodging resistance of a variety is determined genetically and depends on a plant height and weather conditions during dynamic vegetation. One of the main aims of breeding of the crop for lodging resistance is the selection of short-stem varieties. However, a thorough study of the basic material and determination of its adaptability to a particular soil and climatic zone and suitability of its usage as parental forms are needed. The article covers the plant height of collection varieties of winter barley in the central zone of Krasnodar region and determines the groups of the varieties based on this trait. The dynamic of plant height formation depending on the vegetative conditions during five years is studied. The examination of lodging resistance of winter barley revealed that there are many non-lodging forms of the crop. New local varieties and lines have short and strong culms. Also, some varieties from Western Europe and the USA show its good lodging resistance under these conditions

SIMULATION OF A POWER TRANSFORMER WORK WITH A HIGH LEVEL OF HIGHER HARMONICS
DescriptionThe importance of improving the quality of electrical energy was growing along with the development and wide implementation in the production of valve converters and various highperformance processing units, such as arc furnace, welding machines etc. The main causes of potential and existing non-compliances of non-sinusoidal voltages can be joining sources and non-sinusoidal reactive power sources, including resonant filters, to existing electric grids without taking into account their possible impact on the distortion of the sinusoidal voltage. Transformers are affected by the non-sinusoidal shapes of the curves of current and voltage. The effect is characterized by the fact that the harmonics of current and voltage increase transformer temperature, compared to purely sinusoidal current and voltage. The aim of this work is to study the influence of higher harmonics on power loss in power transformers. Experimental study of operation of power transformers was carried out on the developed model of the transformer substation. The experiments were conducted with different capacities of transformers that have variables in the range of 250-1000 kVA. By using programmable voltage source a sinusoidal voltage is formed containing the third, fifth, sixth, seventh, ninth and twelfth harmonics. The level of harmonics is changed in the range of 2-12 %

SOIL PRODUCTIVITY OF DRAIN AGROLANDSCAPES DEPENDING ON THEIR MELIORATIVE CONDITION
06.00.00 Agricultural sciences
DescriptionIn the soils of rice fields, eluvial gley processes develop, which are manifested in redistribution of silty particles along the profile, water-soluble humus, mobile compounds of iron and phosphorus. Most intensively, these processes are developed in meadowbog soils, confined to closed depressions of the plains plain. Meadow-black soils lying on elevated relief elements have more favorable physical, physicochemical and oxidation-reduction properties for cultivating rice and accompanying crops in crop rotation. The highest yield of rice is formed on high checks and higher at 12,4 c/ha than on low ones
