Learned helplessness in the rat: Effect of response topography in a within-subject design
(ELSEVIER SCIENCE BV, 2011)
Three experiments investigated learned helplessness in rats manipulating response topography within-subject and different intervals between treatment and tests among groups. In Experiment 1, rats previously exposed to ...
On the contact stiffness and nonlinear vibration of an elastic body with a rough surface in contact with a rigid flat surface
(Elsevier B.V., 2015-01-01)
The surface topography of engineering rough surfaces has an enormous influence on contact mechanics of the interface and further the dynamics of the contact system. In this paper, the force-deflection characteristic and ...

Thermal and geodynamic contributions to the elevation of the Altiplano-Puna plateau
(Elsevier Science, 2014-10)
The most remarkable feature of the Central Andes is the Altiplano–Puna plateau. This plateau is characterized by 3.5 km average elevation, approximately 70 km crustal thickness and very high heat flow. The upper mantle ...
Topografias de controle de estímulos e equivalência de estímulos : variações paramétricas do procedimento de máscaras
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-graduação em Psicologia, 2012-07-05)
Stimulus equivalence literature has shown robust data, but with some result variability between participants, with some forming classes promptly and others who do not demonstrate the expected class formation. Matching to ...
Operant serial feature-positive conditional discrimination with composite features and different topography responses
(Associação Brasileira de Divulgação Científica, 2008)
In a serial feature-positive conditional discrimination procedure the properties of a target stimulus A are defined by the presence or not of a feature stimulus X preceding it. In the present experiment, composite features ...
Numerical simulations of comminution slurries over complex topographies: Putting together CFD and pipeline integrity
The use of computational fluid dynamics gives new and interesting insights for risk analysis of crosscountry ore hydraulic transport operations. In particular, they offer the possibility to predict, with reasonable accuracy, ...
