INTRODUCTION The purpose of this study was to assess torque and force for simulated canal preparation with a new root canal instrument, ProTaper Next. METHODS Six sets of ProTaper Next Instruments (X1-X5) were used to prepare 36 artificial canals. Files were divided into 6 groups. Different settings of rotations per minute (250, 300, and 350 rpm) and numbers of in-and-out movements to reach w...

We determined if high cadences, during a prolonged cycling protocol with varying intensities (similar to race situations) decrease performance compared to cycling at a lower, more energetically optimal, cadence. Eight healthy, competitive male road cyclists (35 ± 2 yr) cycled for 180 min at either 80 or 100 rpm (randomized) with varying intensities of power outputs corresponding to 50, 65 and 8...

The CoCuFeNi high entropy alloy (HEA) has excellent electrical, thermal, and mechanical properties. In electronic packaging technology, Sn is the major element of lead-free solders. this study, we used HEA as substrate solder investigated liquid/solid interfacial reactions Sn/CoCuFeNi system at 300, 375, 450 °C for 30, 60, 100, 150, 360, 480 min. results indicated that (Fe, Co)Sn2 phase was for...

This study offers a novel solution to deal with the complicated electronic circuitry for speed controller and too complex mechanical design of rotating mechanism an orbital shaker. The developed prototype used transformer that varies supply voltage control rotation has five levels which depend on input voltage. These speeds are 180 rpm at 12 V, 258 15 360 18 427 21 470 24 V. was tested run cont...

Ubiquitination occurs at synapses, yet its role remains unclear. Previous studies demonstrated that the RPM-1 ubiquitin ligase organizes presynaptic boutons at neuromuscular junctions in C. elegans motorneurons. Here we find that RPM-1 has a novel postsynaptic role in interneurons, where it regulates the trafficking of the AMPA-type glutamate receptor GLR-1 from synapses into endosomes. Mutatio...

The fluorescence of Intralipid and polystyrene microspheres with sphere diameter of 1 µm at a representative lipid and microsphere concentration for simulation of mucosal tissue scattering has not been a subject of extensive experimental study. In order to elucidate the quantitative relationship between lipid and microsphere concentration and the respective fluorescent intensity, the extrinsic ...

A ambição deste ensaio então, consiste em, utilizando a recente história nacional desses quase 21 anos, e poucos presidentes, de origens perfis tão diametrais, entender como estes processos alteraram - ou não o curso da história, do Estado brasileiro neste milênio. Para além disso, em continuidade, depreender, nas políticas governo adotadas cada um dos períodos investigados, se estas, foram eiv...
