Mesoscopic behaviour of multi-layered graphene: The meaning of supercapacitance revisited
(2017-01-01)
The electronic density of states and its contribution to the capacitance of graphene compounds (oxidized and reduced) were investigated using an electrochemical impedance-derived capacitance spectroscopic approach. It is ...
Effect of MDP-containing silane and adhesive used alone or in combination on the long-term bond strength and chemical interaction with Lithium Disilicate Ceramics
(Quintessence Publishing Co Inc., 2017)
Purpose: To evaluate the effect of a silane and an adhesive containing MDP, used alone or combined in the same solution, on the microshear bond strength (mu SBS) to lithium disilicate ceramics immediately and after 1-year ...
Influence of the austempering time on the mechanical properties of carbide-free bainitic cast steels
(Springer, 2020-09)
Three medium-carbon, high-silicon cast steels with different alloy contents were austempered at 330 °C for different holding times in order to obtain carbide-free bainitic microstructures. Aiming at evaluating the influence ...
Llegar a ser lo que se es: el valor de la moral de esclavos en Friedrich Nietzsche
(2012)
Se parte de una lectura según la cual la obra de Nietzsche es unitaria y coherente gracias a la continuidad de una meta última relacionada a tareas determinadas. La finalidad es mostrar que la crítica a la moral de ...
Hans Jonas e a diferença antropológica : uma análise da biologia filosófica
(Universidade Federal de Minas GeraisBrasilFAF - DEPARTAMENTO DE FILOSOFIAPrograma de Pós-Graduação em FilosofiaUFMG, 2014-06-16)
This thesis offers an original interpretation of Hans Jonas’ philosophical biology. Initially we will show that jonasian philosophy is marked by the anthropological difference, from which Jonas equates the horizon of modern ...
Surface effects and the size-dependent hardening and strengthening of nickel micropillars
(PERGAMON-ELSEVIER SCIENCE LTD, 2012)
We evaluate the extent to which two mechanisms contribute to the observed size effect of the ultimate yield strength of micropillars of diameters in the range of 1-30 mu m: dislocation pile-ups, modeled by means of a ...

La escencia del ultimate a través del lente fotográfico.
(Corporación Universitaria Minuto de DiosPregrado (Presencial)Licenciatura en Educación Artística, 2020-11-19)
Sabemos que la fotografía es una forma de revolucionar la imagen, aquello que siempre fue cotidiano o hasta demorado en nuestra historia, como lo es la pintura, y el dibujo. lo cual la mayoría de los casos desaparecen o ...
Entre a matéria e a forma: o problema da objetividade dos fenômenos quânticos em Werner Heisenberg
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM FILOSOFIA, 2019-12-11)
This research seeks to problematize Werner Karl Heisenberg's (1901-1976) conceptual
interpretation around the problem of objectivity of quantum phenomena, that is, around the
ancient metaphysical problem, which goes back ...
