8. The results of simulation modeling of the operation of the regenerative fifth wheel hitch of a timber trailer

Author

Nikonov, V O, Posmetev, V I, and Posmetev, V V

Abstract

A three-dimensional mathematical model of the movement of a timber hauler with a semi-trailer along an uneven supporting surface and a computer program developed on its basis are presented that made it possible to evaluate the possibility of equipping the fifth-wheel coupling with an energy recovery system in various driving modes and to study the effect of recovery system parameters on its efficiency.

Abstract

The distribution of bone marrow stromal cells (BMSC) is studied in a 3D poly(L,L-lactide) scaffolds. It is shown that the population of cells seeding into the scaffold with a peristaltic pump (dynamic method) allows the penetration of cells inside of the scaffold compared with the application of the cell suspension on the scaffold surface (static method). In contrast to cells seeding to scaffold by dynamic method the cells seeding by static method migrate from scaffolds in the first few days almost completely. It is found that BMSCs cultured in 3D polylactide scaffold modified by fibrin form colonies, while BMSCs cultured in 3D polylactide-scaffold modified by collagen type I distribute inside scaffold such single cells.
