The Nuss procedure for pectus excavatum repair has been considered an acceptable method in terms of its decreased invasiveness and excellent cosmetic results. Although a steel bar is usually used for elevating the sternum, we used a titanium alloy plate for pectus excavatum repair for the first time. The characteristics of this plate are that 1) it comes out translucently on X-rays, 2) MRI exam...

Although titanium alloys remain the preferred biomaterials for the manufacture of biomedical implants today, such devices can fail within 15 years of implantation due to inadequate osseointegration. Furthermore, wear debris toxicity due to alloy metal ion release has been found to cause side-effects including neurotoxicity and chronic inflammation. Titanium, with its known biocompatibility, cor...

The purpose of this paper is to analyze the use of the Titanium language, a high-performance Java dialect, and parallel programming practices on an application of the Immersed Boundary (IB) Method for simulating biological processes. We will compare two Titanium implementations of the IB Method in terms of performance, developer productivity, and use of Titanium features. The first implementati...

background: the present study aimed to investigate the nailfold capillaroscopy (nc) features of the patients with dermatomyositis (dm) and its correlation with their disease activity indices, physical findings, and laboratory results. methods: the present cross-sectional study was conducted on 27 dm patients above 16 years old who had referred to an(there are 3 clinics not one) outpatient rheum...

Using aMarx-oscillator standing-wave resonancemethod, we measuredthe internal friction &' of sintered titanium containing up to 26 volume-percent voids (c). The surprising &I-versus-c curve shape, an exponential increase, lead us to remeasure &I-versus-c by acoustic-resonance spectroscopy, which gave similar results. We hypothesized that both void shape and void size change with c. For the void...

The present study investigated the influence of archwire size and ligation method on the force magnitude delivered by nickel-titanium alloy archwires to 4 incisor brackets (42, 41, 31, and 32) in a simulation of mandibular right lateral incisor linguoversion. The force delivered by 0.014 and 0.016 inch nickel-titanium alloy archwires was measured using a newly developed multi-sensor measuring s...

Isotopically resolved cross sections and velocity distributions have been measured in charge-pickup reactions of 1 A GeV Pb with proton, deuterium and titanium target. The total and partial charge-pickup cross sections in the reactions Pb + H and Pb + H are measured to be the same in the limits of the error bars. A weak increase in the total charge-pickup cross section is seen in the reaction o...

Pathologic hoof changes in horses and swine can be normalized by administration of biotin. This vitamin has been given orally to women with brittle fingernails or onychoschizia. The aim of the study was to test whether the favorable clinical results could be corroborated by scanning electron microscopy. We investigated the distal ends of the fingernails from 32 persons. They were placed into th...

This letter discusses the role electrical anisotropy plays in the structural integrity assessment of polycrystalline titanium alloys from the standpoint of fatigue crack detection and the related issue of microstructural noise. In eddy current inspection of noncubic crystallographic classes of polycrystalline metals the electric anisotropy of individual grains produces an inherent microstructur...
