1. Mechanical behavior of yttria-stabilized tetragonal zirconia polycrystal: Effects of different aging regimens
Abstract This study aimed to characterize and compare the effect of different aging regimens on surface characteristic (topography and roughness), structural stability (phase transformation) and mechanical performance (Weibull analysis) of a Y-TZP ceramic. Discs (15 × 1.2 mm; VITA In-Ceram YZ) were prepared according to ISO 6872-2015 for biaxial flexural st

3. Efeito do envelhecimento por ciclagem mecânica ou ciclagem em autoclave na resistência à flexão de cerâmicas odontológicas / Mechanical and autoclave cycling effect on flexural strength of dental ceramics
The aims of this study were: to perform a microestrutural analysis of dental ceramics and correlate the results with the flexural strength obtained; to evaluate two aging process (mechanical cycling and autoclave cycling) on the flexural strength of the materials and to evaluate the specimen configuration (bar or disc) on the flexural strength of mechanical

4. Caracterização de sistemas cerâmicos aluminizados infiltrados por vidro, por meio de microscopia eletrônica de varredura e resistência à flexão / Characterization of glass-infused alumina-based ceramic systems by means of scanning electron microscopy and flexural strength
Objective: The purpose of this study was to characterize and compare glass-infused alumina-based ceramic systems by using X-Ray diffraction, scanning electron microscopy (SEM) and flexural strength with a three-point bending test. The ceramic systems used were: (IC)- In-Ceram Alumina (VITA), (VC)- Vitro-Ceram (Angelus) and (AG)- Alglass (Celmat). The c

6. Modeling Membrane Deformations and Lipid Demixing upon Protein-Membrane Interaction: The BAR Dimer Adsorption
We use a self-consistent mean-field theory, designed to investigate membrane reshaping and lipid demixing upon interaction with proteins, to explore BAR domains interacting with large patches of lipid membranes of heterogeneous compositions. The computational model includes contributions to the system free energy from electrostatic interactions and elastic e

7. The function of bursts of spikes during visual fixation in the awake primate lateral geniculate nucleus and primary visual cortex
When images are stabilized on the retina, visual perception fades. During voluntary visual fixation, however, constantly occurring small eye movements, including microsaccades, prevent this fading. We previously showed that microsaccades generated bursty firing in the primary visual cortex (area V-1) in the presence of stationary stimuli. Here we examine the
