Interfacial integrity of low-shrinkage composite restorations related to the filling technique and consistency
(Taylor & Francis Ltd, 2014-09-01)
Purpose: To evaluate the influence of filling techniques and consistency of low-shrinkage composites on the bond strength and internal gap formation in Class I bonded restorations. Two low-shrinkage restorative systems ...
Análise do comportamento da microestrutura de materiais endurecidos retificados com rebolos de CBN
(ABM, ABC, ABPol, 2000-10)
CBN grinding wheels are superabrasive tools, with cutting ability higher than the conventional ones, specially used for grinding DTG (Difficult to Grind) materials. Due to the higher hardness and thermal conductivity of ...
Galerkin finite element method for incompressible thermofluid flows framed within the bond graph theory
(ELSEVIER SCIENCE BV, 2009)
In this paper a bond graph methodology is used to model incompressible fluid flows with viscous and thermal effects. The distinctive characteristic of these flows is the role of pressure, which does not behave as a state ...
Unfolding Ubiquitin by force: water mediated H-bond destabilization
(Pontificia Universidad Javeriana, 2018)
Theoretical aspects of binary and ternary complexes of aziridine⋯ammonia ruled by hydrogen bond strength
(Brasil, 2012)
B3LYP calculations, ChelpG atomic charges, and quantum theory of atoms in molecules (QTAIM) integrations were used to investigate the binary (1:1) and ternary (1:2) hydrogen-bonded complexes formed by aziridine (1) and ...
PRICING VIA ANTICIPATIVE STOCHASTIC CALCULUS
(APPLIED PROBABILITY TRUST, 1994)
The paper proposes a general model for pricing of derivative securities. The underlying dynamics follows stochastic equations involving anticipative stochastic integrals. These equations are solved explicitly and structural ...
Interfacial fracture of dentin adhesively bonded to quartz-fiber reinforced composite
(Elsevier B.V., 2011-05-10)
The paper presents the results of an experimental study of interfacial failure in a multilayered structure consisting of a dentin/resin cement/quartz-fiber reinforced composite (FRC). Slices of dentin close to the pulp ...

Comparing bond strength and marginal integrity with direct bulk-fill resin composites and indirect compositesComparación de la fuerza de unión y la integridad marginal con compuestos de resina de relleno masivo y compuestos indirectos
(2019-04-01)
Introduction: The clinical longevity of tooth restoration -whether directly or indirectly using composites- greatly depends on the quality and stability of the marginal adaptation. Even today, dental restoration failure ...
Retroalimentación de estado de sistemas singularmente perturbados en un enfoque de Bond Graph
(Universidad Michoacana de San Nicolás de Hidalgo, 2014-08)
This thesis proposes the construction of modeling singularly perturbed systems with state feedback on Bond Graph. Taking advantage of the property that have singularly perturbed systems be separable into two subsystems in ...
