INTRODUCTION The purpose of this investigation was to determine the effect that apical preparation size and preparation taper had on the volume of irrigant delivered to the working length of a root canal preparation in a clinically relevant amount of time. METHODS Forty intact human single-rooted teeth were randomly distributed into 2 separate phases. The first phase aimed to determine the sm...

BACKGROUND Methadone is often prescribed as a taper schedule to prevent/treat opioid abstinence syndrome (OAS) or neonatal abstinence syndrome (NAS). OBJECTIVE The objective of this study was to determine the percentage of children discharged home on methadone tapers and to develop, assess, and implement an instrument for measuring the complexity of the methadone regimens. METHODS This stud...

OBJECTIVES The use of ceramic femoral heads in total hip arthroplasty (THA) has increased due to their proven low bearing wear characteristics. Ceramic femoral heads are also thought to reduce wear and corrosion at the head-stem junction with titanium (Ti) stems when compared with metal heads. We sought to evaluate taper damage of ceramic compared with metal heads when paired with cobalt chromi...

background: with the aim of developing methods that could increase the fracture resistance of structurally compromised endodontically treated teeth, this study was conducted to compare the effect of three esthetic post systems on the fracture resistance and failure modes of structurally compromised and normal roots. materials and methods: forty five extracted and endodontically treated maxillar...

Abstract The form-factor for the stem surface area is directly proportional to square root of volume, i.e., law form-factor. Although addresses stems coniferous trees, nature coefficient has not been discussed. In this study, we demonstrated that indicates taper; therefore, it named “Taper Index based on Form-Factor (TIFF).” We also examined relationship between culm and apparent volume 570 cul...

Simulation of phenomena like climate often deals with large datasets. A process to extract the most salient features is needed to assist in the understanding of the dataset. The Morse-Smale (MS) complex is a topological structure defined on scalar functions which extracts critical points of the function and the links between them. Furthermore, it encodes a hierarchy between critical points, and...

In this work, we develop a simulation method based on supermode theory and transfer matrix formalism, and then apply it to the analysis and design of taper couplers for vertically integrated As2S3 and Ti: LiNbO3 hybrid waveguides. Test structures based on taper couplers are fabricated and characterized. The experimental results confirm the validity of the modeling method, which in turn, is used...

A numerical study is presented of the influence of plate curvature and taper on the transport of ultrasound guided wave signals for nondestructive evaluation (NDE) and structural health monitoring (SHM) applications. Model formulations for transmission at sharp transitions in plate curvature and thickness taper are summarized. Results are presented showing that transitions in plate curvature an...
