1. Electroencephalogram Evidence for Memory Suppression: A Systematic Review
Resumo Compreender como as pessoas esquecem é um dos objetivos fundamentais da ciência da memória. Estudos recentes indicam que os humanos podem voluntariamente regular a consciência de memórias indesejadas, interrompendo o processo de recuperação que normalmente levaria experiências passadas para a consciência. A pesquisa de Potenciais Relacionados

2. Analytical Couple-stress Solution for Size-dependent Large-amplitude Vibrations of FG Tapered-nanobeams
Abstract In this paper, analytical couple-stress solution for size-dependent large-amplitude vibrations of FG (functionally-graded) tapered-nanobeams is presented. Using the modified couple-stress theory, the small scale effects are accounted for. Employing the Homotopy-Pade Analysis Method, efficient and accurate analytical expressions for the deflection an

3. Estudo teórico-experimental do efeito da flexão da ferramenta no processo de microfresamento / Theorical and experimental study on tool deflection effect in micromilling process
The tool deflection, in end milling operations, is responsible to intervene negatively on the workpiece surface quality and can also cause a premature tool failure (breakage).The present work aims at studying experimentally the effects of tool deflection when end milling with 0,8 mm diameter in microoperations. The experimental tests had intended to identify

4. Analise do complexo tensão-deformação e mecanismo de falha de pre-molares superiores com diferentes morfologias radiculares e redução sequencial de estrutura dental / Analysis of stress-strain complex and failure mecanism for maxilary premolars with different root morphology and sequential loss of dental structure
The aim of this work was to evaluate the biomechanical behavior of restored maxillary human premolar throughout stress-strain, stress distribtion analysis and fracture resistance with different root morphologies and the cavity preparation design. Forty maxillary premolars with similar coronary dimensions were selected and divided into 4 morphology categories

5. O uso de redes neurais artificiais como ferramenta para auxiliar na determinação da vida útil de pavimentos flexíveis / Using artificial neural networks as a tool to assist in the evaluation of the remaining life of flexible pavements
Este trabalho apresenta um procedimento para auxiliar na determinação da vida útil de pavimentos flexíveis através da determinação de tensões e deformações causadas pela solicitação de um eixo padrão na estrutura de pavimentos flexíveis utilizando Redes Neurais Artificiais. Para treinamento e validação das redes foram utilizadas bacias de def

6. Uma contribuição ao estudo do fresamento de aço endurecido com fresa de topo esferico
The milling of molds and dies cavities carried out on hardened steel using ball end mill presents limitations in terms of cavity depth, metal removal rates and tool life. Some milling operations on deep cavities are not possible due to the require of long tool overhang, what generates vibrations and, consequently, resulted in poor surface roughness and short

7. Ultrasonic Measurements In Brazilian Hardwood
This paper reports on a study of the application of ultrasound waves in wood with the purpose of evaluating the latter's mechanical properties. The evaluation is based on the correlation between the speed of sound, modulus of elasticity and density. The speed of transmission is sensitive to the material's quality-determining factors; hence, this technique is

8. A high-speed atomic force microscope for studying biological macromolecules
The atomic force microscope (AFM) is a powerful tool for imaging individual biological molecules attached to a substrate and placed in aqueous solution. At present, however, it is limited by the speed at which it can successively record highly resolved images. We sought to increase markedly the scan speed of the AFM, so that in the future it can be used to s
