INTRODUCTION The purpose of this study was to evaluate the efficacy of three methods in removal of Resilon/new Epiphany self-etch (SE) soft resin endodontic obturation system. MATERIALS AND METHODS Thirty extracted single rooted human teeth were prepared for endodontic treatment and obturated with Resilon/Epiphany SE. The roots were randomly divided into three groups; group 1 roots were retre...

AIM To assess and compare the shaping potential of manual NiTi K-files and Rotary ProTaper instruments in narrow canals using CT. OBJECTIVE To assess the shaping potential of manual NiTi K-files and Rotary ProTaper and analyzing the final outcome of shaped canals using CT and determining different variables, like • Working time • Change in volume • Change in cross-sectional area. MATERIALS ...

This paper refers to the development of new type rotary compressors suspended with twin springs in a lo~ s1de pressure shell. We compared several types of compress~rs, for example h1gh side pressure shell type, low side pressure shell type, external-suspended type, internal-suspended type, and so on, from the viewpoint of noise reduction, vibration control and transient phenomena such as start-...

Introduction: Root canal instrumentation is an important phase in root canal therapy. Since success in endodontic treatment depends on file defect and fracture, the aim of this study was to compare the evaluation of defect and fracture in rotary and reciproc files in severe curved root canals. Materials & Methods: In this experimental study, 60 mesial canals of human closed apex molars with ...

In this paper, a real-time information service platform for high-speed train was proposed and implemented. With this platform, all passengers of train will freely to get access by Wi-Fi or other wireless network to enjoy movie, music, train information and travel information. Besides, the platform was connected to a FPGA based data processing center to collect train operation data including ins...

Conversion should not be a problem. It is best to use a general accepted tool, which comes with a preprint format. Until BLUe’s format is generally accepted a BLUe script has to converted to comply with publishers’ formats to get it out. Conversion via TEX’s expansion is exercised in this note, with as result a plain TEX Convertor Assistant, in the spirit of AWK. In netland it does not matter b...

INTRODUCTION The aim of this study was to evaluate the root canal preparation in flat-oval canals treated with either rotary or self-adjusting file (SAF) by using micro-tomography analysis. METHODS Forty mandibular incisors were scanned before and after root canal instrumentation with rotary instruments (n = 20) or SAF (n = 20). Changes in canal volume, surface area, and cross-sectional geome...

This paper covers an experimental analysis on capacity estimation for undisciplined intersections/junctions. Rotary intersections are special form of at-grade intersections laid out for the movement of traffic in one direction around a central traffic island. Essentially all the major conflicts at an intersection namely the collision between through and right-turn movements are converted into m...

_ Inverted pendulum control is one of the fundamental and interesting problems in the field of control theory. This paper describes the steps to design various controllers for a rotary motion inverted pendulum which is operated by a rotary servo plant, SRV 02 Series. Nonlinear model of the rotary inverted pendulum and linear model (Upright) in the neighborhood of an equilibrium state are descri...

Transverse and rotary gallop differ in the placement of the leading hindfeet and forefeet: ipsilateral in the former gait, contralateral in the latter. We analysed 351 filmed sequences to assess the gallop type of 89 investigated mammalian species belonging to Carnivora, Artiodactyla and Perissodactyla orders. Twenty-three biometrical, ecological and physiological parameters were collected for ...
