STUDY DESIGN Retrospective case series of one institute database. OBJECTIVE To investigate the differences in the metallic strength of rods used for implant failure in the dual growing rod technique and evaluate clinical outcomes. SUMMARY OF BACKGROUND DATA The dual growing rod technique in which implanted rods extend with the growth of the spine is a useful treatment for early onset scolio...

In this paper, we present a viscoelastic rod model that is suitable for fast and accurate dynamic simulations. It is based on Cosserat’s geometrically exact theory of rods and is able to represent extension, shearing (‘stiff’ dof), bending and torsion (‘soft’ dof). For inner dissipation, a consistent damping potential proposed by Antman is chosen. We parametrise the rotational dof by unit quate...

This paper presents a tapered dielectric rod antenna excited by folded dipole coplanar waveguide operating at terahertz frequencies. The effective refractive index of the plasmonic transmission line is obtained two numerical methods, Finite Element Method and Finite-Difference Time-Domain, it used to obtain dimensions gap connected line. We examine using lengths rod. For 10 5 μm rods, impedance...

The impact of a rigid body and rod finite length made viscoplastic incompressible material moving towards each other at constant velocity is studied in the article. One-dimensional motion considered, i.e., velocity, stress, parameters are considered to be averaged over section. According model viscous-plastic material, divided into two parts: region plastic strain that moves as solid after impa...

Background. The double haul is a unique feature of single-handed fly casting and is used in both fly fishing and fly casting competition. The movement behaviour during the double haul has not been investigated in previous research. Objectives. Describe the coordination of the rod and line hauling movements during distance fly casting. Methods. Elite fly casters performed distance castin...
