in this paper, the modified euler-bernoulli beam model is presented to examine the influence of surface elasticity and residual surface tension on the critical force of axial buckling of nanotubes in the presence of rotary inertia. an explicit solution is derived for the buckling loads of microscaled euler beams considering surface effects. the size-dependent buckling behavior of the nanotube d...

The characteristics of acute deterioration in truncal movements, posture and gait were studied in patients admitted with acute non-neurological disease. Reversible gait abnormalities with characteristics of a 'lower-half parkinsonism' were associated with a disorder of axial movement, disability (as assessed by an activities of daily living score), and low mental test score. There was no associ...

STUDY DESIGN Prospective experimental study on humans. PURPOSE To determine whether postural differences during a low-speed impact are observed in the sagittal and axial views, particularly in a relaxed state. OVERVIEW OF LITERATURE Three-dimensional motion capture systems have been used to analyze posture and head-neck-torso kinematics in humans during a simulated low-speed impact, yet lit...

Understanding kinematics and movement variability (MV) of the axial skeleton (head, thorax, spine, and pelvis) during scrums in Rugby Union is important from a performance and injury prevention perspective. The aim of this study was to investigate repeatability (or MV) of axial skeleton kinematics during one-man simulated scrums. Nine front row players performed scrums against a scrum machine. ...

Effect of time dependent normal transpiration on the problem of unsteady viscous flow and heat transfer in the vicinity of an axisymmetric stagnation point of an infinite circular cylinder moving simultaneously with time-depended angular and axial velocities and with time-dependent wall temperature or wall heat flux are investigated. The impinging free stream is steady with a strain rate . A re...
