When designing modern sports complexes for architects and designers, it is necessary to work out both the ideological and functional aspects of the project. To create comfortable conditions, to ensure the requirements of acoustics, noise insulation and thermal insulation of it from other rooms and the environment, the design of the sports complex's coverage becomes crucial. Bearing coating structures are the most important constructive element of sports facilities. To date, there have been developed sufficiently typical projects with frequently used spans from 18 to 36 m. Coatings with a span of more than 36 m are already considered atypical and are designed individually, based on conditions. Analyzing the existing sports facilities, it was found that a wide distribution as a covering of buildings of sports facilities with a span of up to 60 m was obtained by plane structures: arches, trusses, frames. In this paper, a comparative analysis of the plane structures of the cover for a span of 60 m in the LIRA-SAPR program complex: a truss with steel columns and a steel frame is carried out. All load sensing and effects on structures are specified in accordance with SP 20.13330.2016. The results obtained in the analysis of foreign and domestic experience in the design and construction of these structures can be used at various stages of designing large-span sports complexes.

This monograph deals with the problem of threshing and grain separation in two-phase threshing device of the combine. During combine harvesting, high-quality seeds of soya fall into the total mass of the grain, pass through the entire threshing stage by the first and second drums, cleaning, crushing into halves and small parts and sorted out after post-harvest processing. The authors conclude that with this soybean harvesting technology, more than 50% of the seeds are not receiving the natural resource of yield gain, since the different-quality seeds are not separated or collected separately during the operation of the air-screen cleaning of the combine. According to earlier studies, soybean yield losses are 2.7–3.3 dt/ha.
