Thermal-electric modeling of graphite: Analysis of charge carrier densities and Joule heating of intrinsic graphite rods
(American Institute of Physics, 2017)
Graphite is a versatile material with many applications. Its intrinsic density has been extensively studied and quantified experimentally and theoretically. Experimental data suggest that the electron and hole densities ...
Evaluation of TI-6AL-4V friction surfacing coatings reinforced with carbides
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2017-12-14)
Friction surfacing is a thermo-mechanical process employed to deposit coatings in solid state resorting to friction between a rotating consumable rod and a substrate. The current work focuses on deposition of Ti-6Al-4V ...
Preliminary mechanical evaluation of two novel veterinary angle-stable-threaded interlocking nail systems
(Univ Federal Santa Maria, 2022-01-01)
The interlocking nail represents an excellent option as a surgical approach to treat fractures in long bones in veterinary medicine. However, failures were reported mainly due to a slack present in the interface of the rod ...

Influence of sealing of the screw access hole on the fracture resistance of implant-supported restorations
(2016-03-01)
The purpose of this study was to assess the influence of sealing of the screw access hole (SAH) on the fracture resistance of metal-ceramic implant-supported restorations. UCLA abutments were used to make 30 implant-retained ...
Detecção e classificação de modos de operação do bombeio mecânico via cartas dinamométricas
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia ElétricaAutomação e Sistemas; Engenharia de Computação; Telecomunicações, 2014-05-30)
The precision and the fast identification of abnormalities of bottom hole are essential
to prevent damage and increase production in the oil industry. This work presents a study
about a new automatic approach to the detection ...

Exact relativistic models of thin disks around static black holes in a magnetic field
(2014)
The exact superposition of a central static black hole with surrounding thin disk in presence of a magnetic field is investigated. We consider two models of disk, one of infinite extension based on a Kuzmin-Chazy-Curzon ...
