Background: The aim of this paper is to review the major quantitative and qualitative therapeutic outcomes for gingival recession defects in the esthetic zone. Methods: PubMed and MEDLINE were searched for entries up to April, 2012. For the assessment of quantitative parameters, criteria for considering studies for this assessment was based on the most current systemic review by Chambrone publi...

This article is concerned with using the bootstrap to assign confidence intervals for rotated factor loadings and factor correlations in ordinary least squares exploratory factor analysis. Coverage performances of SE-based intervals, percentile intervals, bias-corrected percentile intervals, bias-corrected accelerated percentile intervals, and hybrid intervals are explored using simulation stud...

When the indemnity schedule is contingent on the farmer’s price and individual yield, an optimal crop revenue insurance contract depends only on the farmer’s gross revenue. However, this design is not efficient if, as is the case with available contracts, the coverage function is based on imperfect estimators of individual yield and/or price. The producer’s degree of prudence and the extent of ...

This paper presents LARES, a novel approach to the modeling of fault-tolerant systems. We introduce a formalism for describing the structure of a system which is able to express dynamic behavior such as imperfect coverage, common cause errors, failure propagation, increase of failure rates after partial system failure, and phased missions. It is designed with the intention to provide a convenie...

This study extends a deterministic mathematical model for the dynamics of tuberculosis transmission to examine impact an imperfect vaccine and other exogenous factors, such as re-infection among treated individuals re-infection. The qualitative behaviors are investigated, covering many distinct aspects disease. proposed is observed show backward bifurcation, even when Rv<1. As such, we assum...

The metal-organic frameworks (MOF) with low and medium specific surface areas (SSA) were shown to be able to adsorb hydrogen via bridged spillover at room temperature (RT) up to an amount of full coverage of hydrogen in the MOF. Anomalous small-angle X-ray scattering was employed to investigate the key relationship between the structures and storage properties of the involved materials. It was ...
