The fish fauna in the fish passage at the Ourinhos Dam, Paranapanema River
(SOC BRASILEIRA ICTIOLOGIASAO PAULO, 2012)
The composition and abundance of the fish assemblage were evaluated in the fish ladder of Ourinhos Dam, the newest dam (closed in 2005) in the cascade of dams constructed on the Paranapanema River. Samplings were carried ...
Ladder Operators for the Spherical 3D Harmonic Oscillator
(Sociedade Brasileira de Física, 2020-12-21)
The Schrödinger equation for an isotropic three-dimensional harmonic oscillator is solved using ladder operators. The starting point is the shape invariance condition, obtained from supersymmetric quantum mechanics. ...
Fish ladders select fish traits on migration - still a growing problem for natural fish populations
(Taylor & Francis Ltd, 2009-01-01)
We investigated the potential selective effect of fish ladders on physiological and morphological profiles of the curimbata, Prochilodus lineatus, during reproductive migration in Brazil. We registered sex, body weight and ...

Convergent validation study of the Contemplation Ladder for application via telephone in tobacco users
(Instituto de Psiquiatria da Universidade Federal do Rio de Janeiro, 2009-01-01)
OBJECTIVE: This work was designed to validate the Portuguese version of the Contemplation Ladder, whose purpose is to assess the motivational phase to quit smoking among tobacco users using a telephone service. METHOD: A ...
Antiparticle Contribution in the Cross Ladder Diagram for Bethe-Salpeter Equation in the Light-Front
(Springer/plenum Publishers, 2009-11-01)
We construct the homogeneous integral equation for the vertex of the bound state in the light front with the kernel approximated to order g(4). We will truncate the hierarchical equations from Green functions to construct ...
