Objectives: To analyze the effect of risedronate hydrogel on enzyme alkaline phosphatase (ALP) and osteoclast/osteoblast ratio during tooth relapse movement
 Materials methods: The research design is experimental with time series. lower incisors 75 guinea pigs are distally moved using open coil spring. were divided into three groups: without (group A; n = 25); given 250 µmol/L B; 25), 500 ...

this paper presents a new method called vespiary regular hexagonal (vrh) model to calculate parasitic capacitance between conductor wire filaments of one turn of a coil and between conductor wires filament and liner and also total capacitance of n-turns having single-layers, multi-conductor wire filaments of the helix magneto cumulative generator (mcg) coil. the presented method is an analytica...

A 4-year-old boy was admitted to our hospital because of sudden-onset abdominal pain that lasted 5 hours. He had no prior history or signs of fever, vomiting, diarrhea, or currant-jelly stools. A physical examination revealed no rebounding tenderness or palpable abdominal mass. A standing plain film of the abdomen revealed no signs of intraperitoneal free air or intestinal obstruction. Intussus...

We demonstrate applications of a new actuator, the Haplug, in dynamic virtual environments. The haplug is a linear voice coil motor packaged between springs in a plug-like casing. Response and bandwidth of the haplug are optimized for haptic interactions, and tuned by the motor inertia and spring stiffness. A pair of haplugs is mounted on the hand-tracking controllers of HTC Vive and renders a ...

We query Web Image search engines with words (e.g., spring) but need images that correspond to particular senses of the word (e.g., flexible coil). Querying with polysemous words often yields unsatisfactory results from engines such as Google Images. We build an image search engine, IDIOM, which improves the quality of returned images by focusing search on the desired sense. Our algorithm, inst...

INTRODUCTION The main advantage of superelastic nickel-titanium (NiTi) products is their unique characteristic of force plateaus, which allow for clinically precise control of the force. The aims of this study were to define the mechanical characteristics of several currently available closed-coil retraction springs and to compare these products. METHODS A universal test frame was used to acq...
