Damage to seeds by screw working bodies.

Seed damage caused by screw working bodies of agricultural machines reduces the seed quality and increases the total cost of crop production. This paper describes the impact interaction of a particle with screw flights when seeds are fed into the transportation zone. There are velocity dependences during the impact and reflection of seeds on the screw surface at the maximum distance of the radius from the screw rotation axis.

Despite its high prevalence, specific programs for postoperative patient rehabilitation have not yet been developed. Traditional approaches to rehabilitation are inferior and are unable to provide a complete recovery process.
