Suppressing Fermi acceleration in a two-dimensional non-integrable time-dependent oval-shaped billiard with inelastic collisions
(Elsevier B.V., 2010-03-01)
Some dynamical properties of a classical particle confined inside a closed region with an oval-shaped boundary are studied. We have considered both the static and time-dependent boundaries. For the static case, the condition ...

Coastal cooling and increased productivity in the main upwelling zone off Peru since the mid-twentieth century
(Wiley, 2011)
We reconstructed a high-resolution, alkenone-based sea surface temperature (SST) record spanning the last ca. 150 years, from a sediment core retrieved within the main upwelling zone off Peru. A conspicuous SST decline is ...
Chronology of deposition and unconformity development across the Cretaceous Paleogene boundary, Magallanes-Austral Basin, Patagonian Andes
(2019)
The Magallanes-Austral foreland basin preserves an important record of orogenesis and landscape evolution in the Patagonian Andes of Chile and Argentina. Throughout the retroarc foreland basin, a regional disconformity ...
Cellular and Molecular Mechanisms of Segmentation in Annelida: An Open Question
(CRC Press - Taylor & Francis Group, 2020)
Annelida is one of the three phyla presenting a segmented body plan, composed of repeated morphological units, and the only lophotrochozoan group with this type of organization. Furthermore, while arthropods and vertebrates ...
Effect of Coriolis acceleration on the span-wise vorticity field over a wind-turbine airfoil
(AIAA, 2022-06-30)
The rotation is known to reduce the volume of the region of separated flow on inboard sections of horizontal-axis wind turbine blades. This reduction is frequently attributed to centrifugal pumping. However, recent ...
Efeito da aceleração de Coriolis sobre o campo de vorticidade no escoamento separado em uma seção de pá de turbina eólica
(Universidade Estadual Paulista (Unesp), 2022-03-25)
A rotação é conhecida por reduzir o volume da região de escoamento separado em seções próximas à raiz de pás de turbina eólica de eixo horizontal. Essa redução é frequentemente atribuída ao bombeamento centrífugo. No ...
