Mechanical behaviour of strain aged dual phase steels
(Materials Science and Technology, 1999-10-01) [Artigo]
Dual phase steels, characterised by good formability and excellent surface finish, are suitable for applications where processing involves cold deformation. In this context an investigation has been conducted into the cold ...
Annihilation, glueball and flavor mixing effects in pseudoscalar mesons
(European Physical Journal C, 1999-12-01) [Artigo]
The pseudoscalar mesons η(547), η′(958) and η″(1410) are studied in the gluonium-quarkonium mixing framework. The SU(3)-flavor symmetry breaking and annihilation effects are considered. Estimates of the glueball mass and ...
Time analysis for temporary gravitational capture: Satellites of Uranus
(Astronomical Journal, 2001-07-01) [Artigo]
We study the problem of gravitational capture in the framework of the Sun-Uranus-particle system. Part of the space of initial conditions is systematically explored, and the duration of temporary gravitational capture is ...
Three-dimensional reconstruction of fracture surfaces: Area matching algorithms for automatic parallax measurements
(Scanning, 1999-07-01) [Artigo]
This paper describes two solutions for systematic measurement of surface elevation that can be used for both profile and surface reconstructions for quantitative fractography case studies. The first one is developed under ...
Radiating cylindrical collapse
(Physics Letters A, 1991-07-22) [Artigo]
The junction conditions for a collapsing cylindrically symmetric source described by a viscous dissipative fluid that conducts heat and produces radiation with outgoing unpolarized radiation are studied. © 1991.
A compound model for the origin of Earth's water
(Astrophysical Journal, 2013-04-10) [Artigo]
One of the most important subjects of debate in the formation of the solar system is the origin of Earth's water. Comets have long been considered as the most likely source of the delivery of water to Earth. However, ...
Effect of commercial mouthwashes on the corrosion resistance of Ti-10Mo experimental alloy
(Journal of Materials Science: Materials in Medicine, 2007-01-01) [Artigo]
The purpose of this work was to evaluate the effect of three commercial mouthwashes on the corrosion resistance of Ti-10Mo experimental alloy. Experiments were made at 37.0 +/- 0.5 degrees C in a conventional three-compartment ...
Braneworlds scenarios in a gravity model with higher order spatial three-curvature terms
(European Physical Journal C, 2013-04-01) [Artigo]
In this work we study a Hořava-like 5-dimensional model in the context of braneworld theory. The equations of motion of such model are obtained and, within the realm of warped geometry, we show that the model is consistent ...
Classes of exact wave functions for general time-dependent Dirac Hamiltonians in 1+1 dimensions
(Physical Review A: Atomic, Molecular, and Optical Physics, 2003-05-01) [Artigo]
The construction of two classes of exact solutions for the most general time-dependent Dirac Hamiltonian in 1+1 dimensions was discussed. The extension of solutions by introduction of a time-dependent mass was elaborated. ...
A synthetic control chart for monitoring the process mean and variance
(Journal of Quality in Maintenance Engineering, 2006-04-10) [Artigo]
Purpose - The aim of this paper is to present a synthetic chart based on the non-central chi-square statistic that is operationally simpler and more effective than the joint X̄ and R chart in detecting assignable cause(s). ...
