Microalgae Schizochytrium sp. in Feed for Piau Leporinus friderici [PDF]

American Journal of Animal and Veterinary Sciences, 2018
The objective of the study was to evaluate the growth of piau (Leporinus friderici) juveniles fed with diet supplemented with different levels of Schizochytrium sp. One hundred and forty juveniles of L. friderici were stocked in 20 aquariums (35 L) at the density of 0.2 fish L-1, weighing and measuring 11.80±1.08 g and 9.68±0.31 cm, respectively.

Effects of Elevated CO2 on Bean Pod Mottle Virus Infection in Both Incompatible and Compatible Interactions With Phaseolus vulgaris L

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant viruses cause significant crop losses, a situation that could worsen due to anthropogenic activities driving global climate change, one factor of which is the increase in atmospheric CO2 concentration. This study assessed the impact of elevated CO2 concentration (eCO2, 1000 vs. 400 ppm) on two genotypes of common bean (Phaseolus vulgaris

Main-Sequence and sub-giant stars in the Globular Cluster NGC6397: The complex evolution of the lithium abundance

, 2009
Thanks to the high multiplex and efficiency of Giraffe at the VLT we have been able for the first time to observe the Li I doublet in the Main Sequence (MS) stars of a Globular Cluster.

Depicting latent variables considering different pig genetics and nutritional plans in crossbred pigs

Revista Brasileira de Zootecnia, 2022
We aimed to reduce the dimensionality of quantitative traits in pigs applying factor analysis. Quantitative variables were collected, and the factor analysis extracted five factors with biological meaning related to performance, carcass quality, carcass ...

The solar energetic balance revisited by young solar analogs, helioseismology and neutrinos

, 2011
The energetic balance of the Standard Solar Model (SSM) results from an equilibrium between nuclear energy production, energy transfer, and photospheric emission.

Finite-size spherical particles in a square duct flow of an elastoviscoplastic fluid: an experimental study [PDF]

, 2019
The present experimental study addresses the flow of a Yield Stress Fluid with some elasticity (Carbopol gel) in a square duct. The behaviour of two fluids with lower and higher yield stress is investigated at multiple Reynolds numbers $Re^* \in$ (1, 200)

Stellar Hydrodynamics in Radiative Regions

, 2003
We present an analysis of the response of a radiative region to waves generated by a convective region of the star; this wave treatment of the classical problem of ``overshooting'' gives extra mixing relative to the treatment traditionally used in ...

Lithium-7 surface abundance in pre-MS stars. Testing theory against clusters and binary systems

, 2012
The disagreement between theoretical predictions and observations for surface lithium abundance in stars is a long-standing problem, which indicates that the adopted physical treatment is still lacking in some points.
