Resolving the planet-hosting inner regions of the LkCa 15 disk
(2016)
LkCa 15 hosts a pre-transitional disk as well as at least one accreting protoplanet orbiting in its gap. Previous disk observations have focused mainly on the outer disk, which is cleared inward of similar to 50 au. The ...

Optical Imaging Polarimetry of the LkCa 15 protoplanetary Disk with Sphere Zimpol
(IOP Publishing, 2015)
We present the first optical (590-890 nm) imaging polarimetry observations of the pre-transitional protoplanetary disk around the young solar analog LkCa 15, addressing a number of open questions raised by previous studies. ...

This study presents the development of a quality control routine for proton magnetic resonance spectroscopy performed on the Siemens Avanto Fit 1,5 T equipment. The objective of this study is to evaluate the repeatability ...
A 3-D perspective to the internal properties of low and high-redshift galaxies
(2019)
In the present work, I study the morpho-kinematics of two moderate galaxy samples at
low- and high-redshift. I analyse the internal kinematics of these galaxies aiming to find
possible correlations between the kinematic ...

Determinação da rigidez da madeira com o emprego de imagens digitais
(Universidade Federal do Espírito SantoBRCiências FlorestaisPrograma de Pós-Graduação em Ciências FlorestaisUFES, 2011-07-05)
Amostras de madeira foram submetidas a ensaio de determinação de rigidez à flexão e à compressão paralela às fibras. A deflexão sofrida pela amostra foi medida por intermédio de relógio comparador (como na norma NBR 7190), ...
Brain mechanisms of serial and parallel processing during dual-task performance
(Society for Neuroscience, 2008-12)
The psychological refractory period (PRP) refers to the fact that humans typically cannot perform two tasks at once. Behavioral experiments have led to the proposal that, in fact, peripheral perceptual and motor stages ...
