Introduction: The present study aimed to compare the cleaning efficacy of passive ultrasonic irrigation (PUI), self-adjusting file (SAF), EndoVac, and conventional syringe irrigation (CSI) techniques on Ca(OH)2 removal from the root canal. Methods: This study was conducted on the mesial roots of 36 human mandibular molar teeth. After 1 month, the Ca(...

UNLABELLED Fluorosis is one of the factors which bring about mineralisation changes in a dentinal structure leading to dentin. The purpose of the present study was to compare and evaluate the dentinal tubular changes in fluorosed and nonfluorosed teeth subsequent to the application of citric acid,strontium acetate based sodium fluoride (SAF) using scanning electron microscopy (SEM). Dentin spec...

The three-phase Shunt hybrid APF topology for harmonic mitigation in low and medium voltage power distribution systems consists of a VSI based three phase shunt active filter (SAF) and tuned passive filters (TPF) connected in parallel with the load. This chapter discusses the modelling of shunt active filter and design of filter interfacing inductor, DC bus capacitor, tuned passive filters. It ...

[1] The zone of highest geodetically defined strain rate in California does not everywhere coincide with the surface trace of the San Andreas Fault (SAF). To determine whether this reflects the pattern of long‐term, permanent deformation, we analyzed the velocity field on swaths across the transform, located so as to avoid intersections among the major fault strands. Slip rates and flexural par...

AIM To introduce a new concept, the self-adjusting file (SAF), and discuss its unique features compared with current rotary nickel-titanium file systems. THE NEW CONCEPT The SAF file is hollow and designed as a thin cylindrical nickel-titanium lattice that adapts to the cross-section of the root canal. A single file is used throughout the procedure. It is inserted into a path initially prepar...

Technology scaling has provided system designers with an exploding transistor budget, far more than what was available when the core principles behind many existing commodity microprocessors were envisioned. With this tremendous growth, however, comes a whole new set of engineering challenges involving power density, thermal efficiency, programmability and so on. In this paper, we study another...

BACKGROUND Blockade of inward-rectifier K+ channels by chloroquine terminates reentry in cholinergic atrial fibrillation (AF). However, it is unknown whether inward-rectifier K+ channels and reentry are also important in maintaining stretch-induced AF (SAF). We surmised that reentry underlies SAF, and that abolishing reentry with chloroquine terminates SAF more effectively than traditional Na+-...
