The article is devoted to the analysis of prospects of application of geoinformation systems (GIS), methods and technologies of remote sensing of the Earth for monitoring and assessment of the state of agricultural lands. The article assesses the possibilities of specialized GIS in improving the efficiency of current crop monitoring, implementation of principles and technologies of organic agriculture. The peculiarities of the structure of perspective GIS for assessing the state and monitoring of agricultural lands are considered. The article describes the main tasks and functions of GIS data, notes the importance of an electronic map as the basis for the integration of cartographic, textual, digital and visual information. The work analyzes the geoinformation system of the region's agro-industrial complex being developed in the Republic of Tatarstan. The main directions of its development have been noted, among which special attention has been paid to the use of unmanned aerial vehicles (UAVs) and UAV-technologies, which create opportunities for the operative collection and processing of large volumes of information in the GIS environment for the purpose of solving the tasks of monitoring and assessment of land conditions, which facilitates the transition to the systems of organic and precision agriculture on the basis of a more reasonable formation of directions of application of biological means of plant protection, development of recommendations on the composition of lands, structure of sowing..

The paper presents a method for studying the process of heat and mass transfer in multiphase media by the example of constructing mathematical models.

This paper discusses the use of electro contact baking of steel powder on a bronze bushing. Its main design parameters are: taper angle of the matrix part - α, deg.; internal diameter of the matrix - D, mm; length of the cylindrical deforming belt - L, mm. To prevent melting of the surface of the restored bronze part, a special electrode was used, which made it possible to bake metal powders onto the bronze surface without melting the part to be restored. The diameter of the crimp die is defined as the difference between the outer diameter of the sleeve before compression and the sum of the wear on the inner surface of the bronze sleeve and the allowance for machining to obtain the nominal size of the inner diameter of the sleeve.

The article presents the results of studies of new electrospark coatings having an amorphous and nanocrystalline structure. The results of metallographic and X-ray diffraction studies are analyzed. The microhardness and thickness of the coatings were studied. For the formation of a nanostructure, a plasma spraying method is used, in which materials are formed upon separate solidification of particles, most often disk-shaped. When the thickness of the sprayed particles is up to 10 μm, they quench from the liquid state at a cooling rate of 108 K / s. Nonequilibrium structures in sprayed particles with a nanocrystalline and amorphous structure have high mechanical properties. However, the use of plasma spraying in some cases is not advisable, due to the relatively high cost of equipment and materials. Therefore, this article will present the results of studies on the creation of amorphous and nanocrystalline coatings using electrospark processing (ESP), which is a cheaper way to obtain them.

Annotation text: the paper presents a method for studying the process of heat and mass transfer, dividing it into three elementary types: thermal conductivity, convection and thermal radiation, as well as examples of these types occurring in reality in multiphase media.
