Deposition of ceramic nanoparticles (dispersed in a non-aqueous suspension) on in-plane electrodes and under the influence of AC electric fields in the frequency range of 0.01 Hz - 10 kHz is investigated. Analysis of the particle response to the applied field is a difficult task due to the mutual effect of electric- and hydrodynamic force which are present in the system. In this work, however, ...

BACKGROUND AND PURPOSE The quadriceps femoris muscle angle (Q angle) is used to reflect the quadriceps femoris muscle's force on the patella in the frontal plane. We found no studies, however, that validate this assumption. The purpose of this study was to determine whether the Q angle can be used to represent the force on the patella in the frontal plane. SUBJECTS Seven lower extremities fro...

Walking, as an important transportation mode, plays a large part in urban transportation systems. This mode is of great importance for planners and decision-makers because of its impact on environmental and health aspects of communities. However, this mode is so complex in nature that makes it difficult to study or model. On the other hand, chaos theory studies complex dynamical nonlinear syste...

In joints with 3 degrees of freedom, such as the shoulder joint, the association of different movements results in changes in the behavior of the moment arm of the muscles. The capacity of torque production for the same movement can be changed when movements take place in a different plane. The objective of this study is to quantify differences between torque production and resultant force esti...

We present results from molecular dynamics simulations of a sphere moving down an inclined plane made rough by glueing other spheres to it. The moving sphere experiences an eeective friction force due to collisions with the balls on the plane, and can maintain a steady state with a constant mean velocity for a certain range of inclination angles of the plane. Although the friction force is due ...

The subject of the study is underground pipeline vibration in a vertical plane, considering inertia rotation and transverse shear. A system differential equations motion an with natural boundary initial conditions under spatial seismic loading derived article. From formulas obtained, it necessary to determine internal forces sections structure. Research methods are based on variational equation...

physical exercise would improve postural stability, which is an essential factor in preventing accidental fall among the elderly population. the aim of this study is to examine the effectiveness of treadmill walking on balance improvement among the elderly people. a total of 30 community dwelling older adults with a berg balance scale score of 36-48 and the ability to walk without aid were cons...
