Recent papers have presented correlations between the radius of curvature of the anterior lens surface and anterior chamber depth (Lowe, I972), and between the anterior lens radius and the anterior and posterior corneal radius (Lowe and Clark, I973). This paper presents measurements of anterior lens radius in relation to age, lens thickness, and axial length in two series comprising 9I normal e...

This paper reports on a dual-axial tool servo diamond turning method for the one-step fabrication of hierarchical micro-nano-structured surfaces. With respect to motion (XZ), z-axis can generate primary surface with complex shape, and x-axis is used synchronously form secondary structure via controlling residual marks. The toolpath determination algorithm developed described in detail, effect m...

OBJECTIVES To compare the biomechanical properties of a new nitinol intramedullary (IM) scaffold implant with those of volar plates for the treatment of dorsally comminuted extra-articular distal radius fractures using an established model. METHODS A dorsal wedge osteotomy was performed on a bone model to simulate a dorsally comminuted extra-articular distal radius fracture. This model was us...

Laminar fully developed ow and pressure drop in linearly varying cross -section converging-diverging microtubes have been is investigated in this work. These microtubes are formed from a series of converging-diverging modules. An analytical model is developed for frictional ow resistance assuming parabolic axial velocity pro le in diverging and converging sections. Frictional ow resistance is f...

Laevens et al. recently discovered TriangulumII (TriII), a satellite of the Milky Way. Its Galactocentric distance is 36 kpc, and its luminosity is only  L 450 . Using Keck/DEIMOS, we measured the radial velocities of six member stars within 1 2 of the center of TriII, and we found a velocity dispersion of s = + 5.1 km s v 1.4 4.0 1. We also measured the metallicities of three stars and fou...

Hydrodynamics analyses as a part of APEX (Advanced Power Extraction) study shows the possibility of applying swirling thick liquid walls to innovative confinement concepts such as Field Reversed Configuration (FRC), Spherical Torus (ST) and Heavy-Ion Fusion (HIF). This paper addresses the design and the hydrodynamic aspects of fusion relevant swirling flow including 3-D velocity distribution, v...

Constitutive models describing the arterial mechanical behavior are important in the development of catheterization products, to be used in arteries with a specific radius. To prove the possible existence of a constitutive model that, provided with a generic set of material and geometric parameters, is able to predict the radius-specific mechanical behavior of a coronary artery, the passive pre...
