Simulations of turbulent convection in rotating young solar-like stars: Differential rotation and meridional circulation

open access: yes, 2007
We present the results of three-dimensional simulations of the deep convective envelope of a young (10 Myr) one-solar-mass star, obtained with the Anelastic Spherical Harmonic code.

Harmonic moments of non homogeneous branching processes

open access: yes, 2005
We study the harmonic moments of Galton-Watson processes, possibly non homogeneous, with positive values. Good estimates of these are needed to compute unbiased estimators for non canonical branching Markov processes, which occur, for instance, in the ...

Overview of the lithium problem in metal-poor stars and new results on 6Li

open access: yes, 2008
Two problems are discussed here. The first one is the 0.4 dex discrepancy between the 7Li abundance derived from the spectra of metal-poor halo stars on the one hand, and from Big Bang nucleosynthesis, based on the cosmological parameters constrained by ...

Swimming performance of the migratory Neotropical fish Leporinus reinhardti (Characiformes: Anostomidae)

open access: yesNeotropical Ichthyology
The fishways built in Latin America were mainly based on those used in the northern hemisphere for passing salmonids upstream. However, the swimming capacity in terms of speed and endurance is a major factor concerning the design of a fishway, and this ...

ASPECTOS REPRODUTIVOS DE Leporinus piau FOWLER, 1941 (OSTEICHTHYES, ANOSTOMIDAE) DA BACIA DO RIO SÃO FRANCISCO, SUBMETIDO À DESOVA INDUZIDA REPRODUCTIVE PARAMETERS OF THE LEPORINUS PIAU FOWLER, 1941 (Osteichthyes, Anostomidae) FROM THE SÃO FRANCISCO RIVER BASIN, SUBMITTED TO INDUCED SPAWNING.

open access: yesCiência Animal Brasileira, 2009
Leporinus piau Fowler, 1941, é importante como peixe forrageiro e na pesca da bacia do São Francisco. Fêmeas dessa espécie foram submetidas à desova induzida, mediante a aplicação de duas doses de extrato bruto de hipófise de carpa-comum (EBHC) (0,5 e 5 ...

The cosmic lithium problem: an observer's perspective

open access: yes, 2012
Using the cosmological constants derived from WMAP, the standard big bang nucleosynthesis (SBBN) predicts the light elements primordial abundances for 4He, 3He, D, 6Li and 7Li. These predictions are in satisfactory agreement with the observations, except
