BACKGROUND The increasing complexity of articulating spinal implants prohibits the use of serum-supplemented simulator fluid testing because multicomponent interfaces retain residual protein and preclude gravimetric measurement. Our original hypothesis was that simulator testing of a posterior dynamic stabilization implant that has metal-on-metal articulating bearings will not produce dramatica...

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract The Integrated Development Environment (IDE) provides many debugging tool to limit coding errors and facilitate error correction. It avoids software failure, reduce development and maintenance cost, improve customer agreement and software quality. ...

A solar eclipse provides a well-characterized reduction in solar radiation, of calculable amount and duration. This captivating natural astronomical phenomenon is ideally suited to science outreach activities, but the predictability of the change in solar radiation also provides unusual conditions for assessing the atmospheric response to a known stimulus. Modern automatic observing networks us...

Objective—To monitor the eVect of a novel nicotine delivery device that may produce fewer carcinogens (Eclipse) on cigarette smoking, carbon monoxide and nicotine concentrations, and motivation to give up smoking. The smoker’s own brand of cigarette and a nicotine replacement product (Nicotrol inhaler) were used as comparisons. Design—After baseline data were recorded, smokers were randomised t...

This study examined whether pilots operating a flight simulator completed digital or paper flight checklists more accurately after receiving postflight graphic and verbal feedback. The dependent variable was the number of checklist items completed correctly per flight. Following treatment, checklist completion with paper and digital checklists increased from 38% and 39%, respectively, to nearly...

We report on two ASCA observations of the high-mass X-ray binary pulsar OAO 1657−415. A short observation near mid-eclipse caught the source in a lowintensity state, with a weak continuum and iron emission dominated by the 6.4-keV fluorescent line. A later, longer observation found the source in a high-intensity state and covered the uneclipsed through mid-eclipse phases. In the high-intensity ...

UNLABELLED While utilizing removable dentures, regardless of whether the dentures are acrylic or fabricated of eclipse resin, the need for their filling-relining or their repair frequently arises. The purpose of this study is to display the technicalities of the procedure for rebasing and relining of removable light curing eclipse denture resin. MATERIAL AND METHODS This study presents cases ...

As the future pervasive and ubiquitous computing environment will be composed of resources from local computing, Grid, SOA and Web infrastructures, the complexity of this distributed system will increase significantly. At the same time the end user wants easy and simple access to his computing environment while he receives more responsibilities i.e. for the composition and the management of the...
