Influence of different wavelengths peaks in LED units on the degree of conversion of orthodontic composites
(Elsevier B.V., 2016-12-01)
Objective: The aim of this study was to assess the influence of adding a second wavelength peak (400 nm) to a light-emitting diode (LED) unit on the degree of conversion (DC) of two commercial orthodontic composites, as ...
Examining the relation between practicing meditation and having peak experiences and lucid dreams. A cross-sectional study
(Frontiers Media, 2022)
The aim of this study was to compare meditators and non-meditators in terms of their tendency to have peak experiences and their dream lucidity, while examining the associations between these outcomes and some related ...
Effects of acetylation and acetylation-hydroxypropylation (dual-modification) on the properties of starch from Carioca bean (Phaseolus vulgaris L.)
(Springer, 2015-01-01)
Carioca bean is an important product of Brazil and its major components are protein and starch. In its native form, starch has some technological constraints and modifications can improve its properties. Acetylation ...
Enhanced dual-spectrum line interpolated FFT with four-term minimal sidelobe cosine window for real-time harmonic estimation in synchrophasor smart-grid technology
(2019-02-01)
The proliferation of nonlinear loads and integration of renewable energy sources require attention for accurate harmonic estimation along with estimation of fundamental amplitude, phase, and frequency for protection, ...
Improved dual sinc pulses to reduce ICI power and PAPR in OFDM-based systems
(Ksii-Kor Soc Internet Informationkor SCI & Technol CTR, 2020)
A newfangled family of Nyquist-I pulses is proposed and named improved dual sinc pulse
(IDSP). The IDSP is designed to improve performance in orthogonal frequency division
multiplexing (OFDM)-based systems. The IDSP is ...
Dual task interference on postural sway, postural transitions and gait in people with Parkinson's disease and freezing of gait
(2017-07-01)
Freezing of gait (FoG) is associated with less automatic gait and more impaired cognition, balance and postural transitions compared to people with PD who do not have FoG. However, it is unknown whether dual-task cost ...
The abundances and properties of Dual AGN and their host galaxies in the EAGLE simulations
(2019)
We look into the abundance of Dual AGN (active galactic nucleus) in the largest hydrodynamical simulation from the Evolution and Assembly of GaLaxies and their Environment (EAGLE) project. We define a Dual AGN as two active ...
Hand grip strength and maximum peak expiratory flow: Determinants of bone mineral density of adolescent students
(BioMed Central Ltd., 2018)
Mesospheric wind estimation with the Jicamarca MST radar using spectral mainlobe identification
(American Geophysical Union, 2019-12)
MST (mesosphere, stratosphere, troposphere) radar observations at Jicamarca use four antenna beams, one vertical, others tilted to the east, west, and south, to detect the scattered pulse returns from mesospheric heights ...
Effects on intermittent postural control in people with Parkinson's due to a dual task
Objectives: The aim of the present study was to determine the effects of performing a dual task on the sway density plot parameters in Parkinson's disease and control subjects.& nbsp;Methods: A cross-sectional design was ...
