In the first stage, a parent flow inside an internal cone shaped from a special dual-inflection-point generatrix is optimized for the improvements of total pressure recovery and flow uniformity.
The fixation system is made of a titanium alloy, and composed of an expandable cylinder screw with an internal cone-shaped space.
It refers to either a sleeve that inserts into the femoral head (as with the ASR XL head system) or simply to the internal cone of the head in systems not using a sleeve adaptor (such as the Pinnacle system (DePuy) that uses an "Articuleze" femoral head).
The influence of insertion depth and interimplant distances (i.e. 2 and 3 mm) at two-piece SLA-surfaced implants (internal Morse cone connection, platform-switched configuration, length: 9 mm, outer diameter 4.5 mm) was investigated by Barros et al.
The cone morphotype showing the best set of internal details is cone morphotype 2 (Fig. 1, cone 2; Figs. 4, 5), in which the seeds, cone scales, cone axis, and vascular system are visible in the digital images (Figs. 4B, 5A).
Hence, our observations argue against a major role of depolarization, voltage-activated Ca2+ influx, mitochondrial overload and Ca2+ release from internal stores in cone and rod death driven by Pde6 mutations.
Internal state of growth cone : Inside a growth cone biochemical reactions take place that determine the growth cone's dynamics (Song et al., 1998 ; Song and Poo, 1999 ).
Thus, it was generally found that among the five cone morphotypes, two display clear internal structure (Fig. 1, cones 2 and 5), two show indistinct traces of internal structure (Fig. 1, cones 1 and 3), and one is obviously a natural cast in which only the external surface of the cone is preserved (Fig. 1, cone 4).
The aim of this study was to obtain a better understanding of the internal structure of the cones and of the forming conditions under which such silicates precipitate.
In the case of the fossil conifer cones, these internal structures were primarily the seeds, vascular system, or cone scales.
