Gear grinding with dish wheels
(1999)
A study was conducted to analyze the possibilities for the selection of tool adjustments to reduce tooth profile errors and running distance and time during grinding of gears with dish wheels. The selection of parameters ...

Selection of geometric parameters of gear and grinding wheel to ensure maximum gear tooth profile accuracy
(2005)
An analysis of possibilities for the selection of gear and tool geometry parameters is presented to reduce tooth profile errors during the grinding of gears by double tapered wheel (Hofler or Niles method), double wheel ...
Oxidative dissolution of chalcopyrite by Acidithiobacillus ferrooxidans analyzed by electrochemical impedance spectroscopy and atomic force microscopy
(Elsevier B.V., 2004-08-01)
The microbiological leaching of chalcopyrite (CuFeS2) is of great interest because of its potential application to many CuFeS2-rich ore materials. However, the efficiency of the microbiological process is very limited ...
Electrochemical corrosion behavior of a Ti-35Nb alloy for medical prostheses
(Pergamon-elsevier Science LtdOxfordInglaterra, 2008)
Minimality in diagrams of simplicial sets
We formulate the concept of minimal fibration in the context of fibrations in the model category SC of C-diagrams of simplicial sets, for a small index category C. When C is an EI-category satisfying some mild finiteness ...

Influence of the addition of SiO2 nanoparticles to a hybrid coating applied on an AZ31 alloy for early corrosion protection
(2016-10-15)
This work aims to investigate the corrosion resistance of AZ31 magnesium alloy protected by hybrid films based on tetraethylorthosilane (TEOS) and (3-glycidoxypropyl)trimethoxysilane (GPTMS) with the addition of different ...
Characterization of bornite (Cu5FeS4) electrodes in the presence of the bacterium Acidithiobacillus ferrooxidans
(2003-10-02)
Bornite electrodes were characterized in the absence or in the presence of Acidithiobacillus ferrooxidans, which is an important microorganism involved in metal bioleaching processes. The presence of the bacterium modified ...
