Sphericity of apatite particles determined by gas permeability through packed beds
(SOC MINING METALLURGY EXPLORATION INC, 2009)
Because shape is an assessment of the three-dimensional form of a particle, it may be described in terms of sphericity (Psi), which is a measure of how closely a particle approaches a spherical configuration. In this study, ...
A PC compatible Brazilian software for obtaining thermal histories using apatite fission track analysis
(Elsevier B.V., 2001-06-01)
In this work a software developed in the Instituto de Fisica Gleb Wataghin, IFGW, UNICAMP, Campinas, SP, Brazil for obtaining thermal histories using apatite fission track analysis is presented. This software works in ...
Surface tension of flotation solution and its influence on the selectivity of the separation between apatite and gangue minerals
(SOC MINING METALLURGY EXPLORATION INC, 2009)
This work presents and discusses the influence of the surface tension (gamma(LV)) of methanol/water mixtures on the flotation response of apatite versus gangue minerals conditioned with flotation reagents (75 g/t cornstarch ...
Projected length annealing of etched Sm-152 ion tracks in apatite
(Elsevier Science BvAmsterdamHolanda, 2012)
Recognition of Cretaceous, Paleocene, and Neogene tectonic reactivation through apatite fission-track analysis in Precambrian areas of southeast Brazil: Association with the opening of the south Atlantic Ocean
(2003-01-01)
Apatite fission-track analysis was used for the determination of thermal histories and ages in Precambrian areas of southeast Brazil. Together with geological and geomorphologic information, these ages enable us to quantify ...
Projected length annealing of etched Sm-152 ion tracks in apatite
(Elsevier B.V., 2012-10-01)
Slices of apatite (cut similar to 45 degrees apart from c-axis) were irradiated with Sm-152 ions and heated at different steps in order to investigate the thermal annealing property of tracks generated by these ions. The ...
Enhanced bioactive properties of biodentine™ modified with bioactive glass nanoparticles
(2017-03-01)
Objective To prepare nanocomposite cements based on the incorporation of bioactive glass nanoparticles (nBGs) into BiodentineTM (BD, Septodent, Saint-Maur-des-Fosses Cedex, France) and to assess their bioactive properties. ...
Durango apatite fission-track dating using length-based age corrections and neutron fluence measurements by natural thorium thin films and natural U-doped glasses calibrated through natural uranium thin films
(Elsevier B.V., 2002-08-01)
In this work, we present an approach for neutron fluence measurements based on natural thorium thin films and natural uranium-doped glasses calibrated through natural uranium thin films to be used for dating with the ...
Further investigation of the initial fission-track length and geometry factor in apatite fission-track thermochronology
(2013-08-01)
The external detector method (EDM) is a widely used technique in fission track thermochronology (FTT) in which two different minerals are concomitantly employed: spontaneous tracks are observed in apatite and induced ones ...
Apatites coating in vitro on titanium - influence of the thermal treatment
(Editora Unesp, 2003-01-01)
Commercially pure titanium (cp-Ti), and some of its alloys are considered very important in the medical field because of its excellent biocompatibility and mechanical properties. Recently a simple chemical, method was ...
