Comparative cutting effectiveness of an ultrasonic diamond tip and a high-speed diamond bur.
(2009-03-01)
AIM: The aim of this in vitro study was to compare an ultrasonic diamond tip to a high-speed conventional diamond bur regarding the cutting effectiveness in enamel and dentin of human teeth. METHODS: Twenty permanent molars ...
Fluid description of the cooperative scattering of light by spherical atomic clouds
(Cambridge University PressCambridge, 2013-08)
When a cold atomic gas is illuminated by a quasi-resonant laser beam, light-induced dipole-dipole correlations make the scattering of light a cooperative process. Once a fluid description is adopted for the atoms, many ...
Scattering of intersecting spherical particles in the Rayleigh-Gans approximation
(Elsevier, 2011-02-01)
In this work a novel semianalytical procedure to calculate the exact scattering behavior of complex particles made of intersecting spheres in the Rayleigh-Gans approximation is presented. Pickering emulsions, Janus ...
Construção, caracterização e aplicação de eletrodos para descarga por arco de cátodo oco
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia de MateriaisProcessamento de Materiais a partir do Pó; Polímeros e Compósitos; Processamento de Materiais a part, 2008-06-27)
The system built to characterize electrodes and, consequently, deposited fine films are constituted by a hollow cathode that works to discharges and low pressures (approximately 10-3 to 5 mbar), a source DC (0 to 1200 V), ...
Endohedrally confined hydrogen atom with a moving nucleus
(IOP Publishing, 2016-11-16)
We studied the hydrogen atom as a system of two quantum particles in different confinement conditions; a spherical-impenetrable-wall cavity and a fullerene molecule cage. The motion refers to the center of spherical cavities ...
