The study of issues related to the state soil on surface most constant technological track is relevant, since movement running wheels along narrow tracks determines traction and coupling properties machine-tractor units, their vibrations, stability controllability movement. рurpose this was increase efficiency process profiling microroughnesses located in areas that form a which units will move...

Abstract Copper heaters were made. On the surface of these arrays micrococoons synthesized from silicon oxide (SiO x ) nanowires with different concentrations micro/nanostructures and hence average distances between them. Boiling curves obtained for samples it was found that heat transfer enhancement during boiling occurs on them in comparison a smooth copper surface. It shown effect increases ...
