Orthodontic brackets removal under shear and tensile bond strength resistance tests - a comparative test between light sources
(WILEY-V C H VERLAG GMBH, 2008)
We have investigated if a new LEDs system has enough efficient energy to promote efficient shear and tensile bonding strength resistance under standardized tests. LEDs 470 +/- 10 nm can be used to photocure composite during ...
Numerical and Experimental Analysis of Wood Tensile Strength Perpendicular to the Grain
(2022-01-01)
The Brazilian Code ABNT NBR 7190 (1997) is currently under review process and one of the proposals is the change and add of some test procedures. Several specimen geometric configurations and test conditions have been ...

Effect of the Layering Technique on Bond Strength and Cohesive Resistance of a Porcelain-Zirconia System
(Quintessence Publishing Co Inc, 2014-01-01)
Purpose: To evaluate the influence of the number of porcelain layers on its cohesive strength and on bonding to zirconia.Materials and Methods: Y-TZP blocks were cut into 1 cm(3) specimens (n = 30). The feldspathic porcelain ...
Influência de diferentes agentes de fixação na resistência de união, por tração, de ligas metálicas fixadas à dentina.
(1990-12-01)
They were casted pieces using three kinds of alloy (Ni-Cr, Ag-Sn and Cu-Al) with circular and smooth surface. They were cemented to human teeth, on occlusal surface, grounded at dentin level, through three different materials ...
Dendritic microstructure affecting mechanical properties and corrosion resistance of an Al-9wt% Si alloy

Simple green approach to reinforce natural rubber with bacterial cellulose nanofibers
(2013-08-12)
Natural rubber (NR) is a renewable polymer with a wide range of applications, which is constantly tailored, further increasing its utilizations. The tensile strength is one of its most important properties susceptible of ...
Influence of EVA and acrylate polymers on some mechanical properties of cementitious repair mortars
(ELSEVIER SCI LTD, 2009)
In repair works of reinforced concrete, patch repairs tend to crack in the interfacial zone between the mortar and the old concrete. This occurs basically due to the high degree of restriction that acts on a patch repair. ...
Ação do diclofenaco de sódio, após a interrupção da peritonite estercorácea, no cólon de ratos. Estudo da resistência mecânica e do colágeno tecidual.
(1995-09-01)
The objective of the present study was to investigate changes in colon wall in rats with fecal peritonitis (Per) associated with sodium diclofenac (SD) by studying breaking strength and tissue collagen concentration. The ...
