W pracy przedstawiono symulacje sił wymaganych do uniesienia głowy niemowlęcia w pozycji supinacyjnej przy podciąganiu za kończyny górne. Symulację przeprowadzono dla 3-miesięcznego niemowlęcia o sile naturalnego obciążenia 47,1 N. Założono, że kąt nachylenia linii działania siły przy podciąganiu za kończyny górne do poziomu wynosi od 15°−60°, a siły mostkowo-obojczykowo-sutkowej wynosi od 5°−15°...
The hydrodynamic lubrication of the human biobearing gap in the orthogonal curvilinear coordinate jystem is described. The axisymmetrical flow in the biobearing gap between two arbitrary rotational )ithogonal curvilinear surfaces with non-monotonic generating line in the longitudinal direction and changeable height of gap is considered. As a particular case the analytical and numerical characteristics...
