Estudo comparativo da textura superficial entre os materiais estéticos indiretos

The purpose of this study was to evaluate surface rugosity among indirect esthetic materials (Vita VMK 95, Solidex, Artglass, Targis). Ten samples of each material in the cilindric shape with dimension 6 x 6 mm were manufactured. The surface were submitted to finishing and polishing, according to manufacturer's recommendations. The samples were submitted to measuremenst, using the Hommel Tester T500 device. The average values of maxim surface rugosity among the materiais ín question, were 5, 73pm; 5, 15pm; 6, 83 j.Jm e 3, 72 j.Jm, respectively. Sample were also subjectted to variance analysis- ANOVA (5%), had detected significance. Concluded that the material Solidex did not present significant statistical differences among groups, while Targis presented significant statistical differences in relation to the Artglass and the ceramic Vita vmk95.

Using of a snap-through truss absorber in the attenuation of the sommerfeld effect

This work, considers a vibrating system, which consists of a snap-through truss absorber (STTA) coupled to an oscillator, under excitation of an DC motor, with an eccentricity and limited power, characterizing a non-ideal oscillator (NIO). It is aimed to use the absorber STTA, to establish the conditions, that we have the maxim attenuation of the jumpphenomenon (Sommerfeld Effect). Here, weare interestedin determining the conditions of the vibrating system, in which there arereduced amplitudes of the oscillator, when it passes through the region of resonance.
