Subsoiling (SS) is an important technology in conservation tillage, but soil-disturbance characteristics the SS are rarely described. Research on during conducive to design and optimization of subsoilers, which provides a basis for reducing draft force energy consumption. This study conducted experiments at five different tillage depths field with specific situ test-rig facility, videotaping wa...

The parameters of the surface microrelief are paramount in problems frictional interaction parts, flow liquid and gas channels, ensuring required thermal conditions stress-strain state structure. solution problem optimal regime for a significant range technical products often becomes decisive design operating under high-intensity heat flows. Transit fluxes flowing through product, as well from ...

Abstract Occurrence and distribution of microplastics in different ecosystems have recently become subjects numerous studies. However, to date the research has focused mainly on marine freshwater widely neglected terrestrial environments. Only recently, first studies investigated contamination soils. Therefore, we know little about transport mechanisms soils sediments virtually nothing their su...

The article deals with an actual task of developing engineering methods for predicting the durability modern long-life machines should be based on methodology determining degree fatigue damage to materials and structural elements. In development such a methodology, work proposes use optical computer tools that allow analyzing parameters deformed surface metal structure samples and, this basis, ...

The use of digital elevation models (DEMs) that airborne-based light detection and the ranging technique (airborne-based LiDAR) to understand large-scale geological structures has become important in surveying mapping. Taking Dongao Tunnel area northeastern Taiwan as study area, this used LiDAR DEM related value-added maps interpret topographic geomorphic features identify locations for investi...

Analysis of research and development pre-sowing machines units shows that there are many trailed, semi-trailer combined with different design technical characteristics. In general, the significant disadvantages these aggregates insufficient quality flatness microreliefs fragmentation soil. Compared to basic complex use a machine, proposed unit contributes to: decrease in density soil at level 0...

The paper deals with the study of taxonomic structure floodplain and dry meadow communities Bolshaya Kokshaga State Nature Reserve Republic Mari El. dependence between meso- microrelief territory conditions plant growth is revealed. It has turned out that flora studied 12 phytocoenoses (6 6 dryland) includes 174 species vascular plants belonging to 110 genera from 36 families. leading families ...

Abstract The multifractal analysis (MFA) of the spatial microform area formed on surface steel C35 and aluminum alloy AA2024 at face milling was implemented. input information for MFA micro-images machined workpiece surface. Multifractal (MF) spectra their main parameters are calculated samples various cutting conditions. Renyi’s numbers fractal ordering were chosen as most informative MF descr...
