Desenvolvimento e análise de suporte para melhoria em ensaio de névoa salina
(Universidade Tecnológica Federal do ParanáLondrinaBrasilEngenharia de MateriaisUTFPR, 2017-05-19)
The Salt Spray test consists of an accelerated corrosion test that simulates the actual weathering conditions, aiming at the preliminary evaluation of materials, especially metallic ones, when in contact with a marine ...
The effect of endodontic materials on the optical density of dyes used in marginal leakage studies
(2008-01-01)
The aim of this study was to determine the effect of the exposure of different endodontic materials to different dye solutions by evaluating the optical density of the dye solutions. Seventy-five plastic tubes were filled ...
Sealing ability of retrograde obturation materials containing calcium hydroxide or MTA
(2011-12-01)
Newly available materials for retrograde obturation should have their sealing properties evaluated. The goal of this study was to evaluate the sealing ability of Endo CPM sealer, an MTA-based endodontic cement. Single-rooted ...

(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Construção Civil, 2012-04-12)
Concrete is the most used material in construction and better suited to resist compressive loads. Since it an indispensable material and that in its aging is subject suffering from various types of conditions and with high ...
Remarks on orthotropic elastic models applied to wood
(2006-07-01)
Wood is generally considered an anisotropic material. In terms of engineering elastic models, wood is usually treated as an orthotropic material. This paper presents an analysis of two principal anisotropic elastic models ...

The effect of locked screw angulation on the biomechanical properties of the S.P.S. Free-Block plate
(2013-03-27)
Objectives: Among the locked internal fixators is one denominated S.P.S. (Synthesis Pengo System) Free-Block, which was designed with a locking ring that allows the screw to be locked and positioned obliquely. Due to the ...
