Influence of rotational speed on torque/force generation and shaping ability during root canal instrumentation with continuous rotation and optimum torque reverse motion.

International Endodontic Journal, 2021
AIM To evaluate how different rotational speeds affect the torque/force generation and shaping ability of rotary root canal instrumentation using JIZAI (MANI, Japan) nickel-titanium instruments in continuous rotation and optimum torque reverse (OTR ...

Evapotranspiration and Water Use Efficiency of Continuous Maize and Maize and Soybean in Rotation in the Upper Midwest U.S.

Agricultural Water Management, 2019
This study examined evapotranspiration (ET) from no-till, rainfed maize and soybean during three growing seasons (May-Sep) of normal rainfall years (2009, 2010, 2011) and a drought year (2012) in Michigan, USA, based on daily soil water uptake measured ...

Continuous rotation of eccentric triboelectric nanosensor under low frequency periodic vibration

, 2020
Abnormal vibration and external impact are critical issues to mechanical structures as they can sometimes cause fatigue or even failure. An Eccentric Triboelectric Nanosensor (Ec-TENS) model has been proposed in our previous study to monitor these ...

Alternating Versus Continuous Rotation: A Comparative Study of the Effect on Instrument Life

Journal of Endodontics, 2010
ntroduction Rotary nickel-titanium instruments have multiple advantages but with the risk of more fractures because of flexure or torsion. Alternating rotation appears to be an alternative to continuous rotary movement. The objective of this study was to

A Porous Cobalt Tetraphosphonate Metal-Organic Framework: Accurate Structure and Guest Molecule Location Determined by Continuous-Rotation Electron Diffraction.

Chemistry, 2018
Single-crystal electron diffraction has shown to be powerful for structure determination of nano- and submicron-sized crystals that are too small to be studied by single-crystal X-ray diffraction.

Variations in soil aggregate distribution and associated organic carbon and nitrogen fractions in long-term continuous vegetable rotation soil by nitrogen fertilization and plastic film mulching.

Science of the Total Environment, 2022
Small changes in soil aggregates-associated organic carbon (OC) can induce huge fluctuations in greenhouse gas emissions. However, there is a knowledge gap on the responses to nitrogen (N) fertilization under plastic film mulching, especially in long ...
