Fadiga de grampos de retenção em prótese parcial removível. Efeito de ligas, espessuras e técnicas de fusão. Parte II.
(1990-12-01)
The authors tested the T clasp of Roach in three differents proportions among width and thickness: E1-1.7; E2-2.0 and E3-2.3, with a constant length of 15 mm. These clasps were casted with three cobalt-chromium alloys ...
The determination of iron, lead, copper and zinc in the hair of children between 22 and 85 months old
(1989-09-01)
In this study the levels of Cu, Fe, Pb and Zn, determined in hair of healthy children (25-85 months), living at Araraquara (São Paulo, Brasil) are reported. Analytical determinations were carried out by using atomic ...
Optical and electrical properties of polymerizing plasmas and their correlation with DLC film properties
(Springer, 2004-03-01)
Diamond-like carbon (DLC) films were grown from radiofrequency plasmas of acetylene-argon mixtures, at different excitation powers, P. The effects of this parameter on the plasma potential, electron density, electron ...
DETERMINATION of SILICON IN LUBRICANT OIL BY HIGH-RESOLUTION CONTINUUM SOURCE FLAME ATOMIC ABSORPTION SPECTROMETRY USING LEAST-SQUARE BACKGROUND CORRECTION and INTERNAL STANDARDIZATION
(Taylor & Francis Inc, 2011-01-01)
The least-squares background correction (LSBC) and internal standardization procedures were combined to eliminate spectral interferences caused by the CS molecular band (251.602 nm) and transport effects for determining ...
Efeito do fósforo na captação de minerais e pigmentação de Azolla caroliniana Willd. (Azollaceae)
(Sociedade Botânica de São Paulo, 2004-09-01)
O bioacúmulo de minerais, a fixação de nitrogênio e a concentração de pigmentos em Azolla caroliniana foram estabelecidos sob estresse nutritivo. As culturas foram mantidas em frascos de poliestireno, utilizando gradiente ...
Fadiga de grampos de retenção em prótese parcial removível. Efeito de ligas, espessuras e técnicas de fusão. Parte I.
(1990-12-01)
The authors looked for the verification of the fatigue of retentive clasps utilized on the removable partial denture. According to this, it was idealized and built on assay machine, that through movements, simulate the ...

Mechanical and tribological properties of a-C:H:F Thin Films
(2013-07-01)
a-C:H films were grown by plasma-enhanced chemical vapor deposition in atmospheres composed by 30 % of acetylene and 70 % of argon. Radiofrequency signal (RF) was supplied to the sample holder to generate the depositing ...
Sistema TS-FF-AAS com chama acetileno-ar como alternativa em relação à chama acetileno-óxido nitroso em FAAS na determinação de estanho
(Editora Unesp, 2005-01-01)
Este trabalho propõe o desenvolvimento de um procedimento analítico para a determinação em linha de estanho em soluções analíticas empregando a técnica de espectrometria de absorção atômica com nebulização térmica em tubo ...
