The influence of the photoperiod on productive performance and survival of piabanha-of-Pardo (Brycon vonoi ), hatchery

open access: yesCiência Rural, 2018
: This research aimed to verify the influence of the photoperiod on the performance and survival piabanha-of-Pardo (Brycon vonoi) larvae. Piabanha-of-Pardo larvae 24 hours post-hatch, with body weight of 2.44 ± 0.02mg, and total length of 7.82 ± 0.46mm ...

Effects of light intensity on the distribution of anthocyanins in Kalanchoe brasiliensis Camb. and Kalanchoe pinnata (Lamk.) Pers

open access: yesAnais da Academia Brasileira de Ciências, 2012
This paper compares two medicinal species of Kalanchoe, which are often used interchangeably by the population, regarding the distribution of anthocyanins under the influence of four luminosity levels for 6 months.

Full-data Results of Hubble Frontier Fields: UV Luminosity Functions at z ∼ 6–10 and a Consistent Picture of Cosmic Reionization [PDF]

open access: yes, 2017
We present UV luminosity functions of dropout galaxies at with the complete Hubble Frontier Fields data. We obtain a catalog of ∼450 dropout-galaxy candidates (350, 66, and 40 at , 8, and 9, respectively), with UV absolute magnitudes that reach mag, ∼2 ...

The Properties and Luminosity Function of Extremely Low Luminosity Galaxies [PDF]

open access: yesThe Astrophysical Journal, 2005
We examine a sample of low redshift (10 < d < 150 Mpc) galaxies including galaxies with r-band absolute magnitudes as faint as -12.5 (for h=1), selected from the Sloan Digital Sky Survey Data Release 2 (SDSS). The sample is unique in containing galaxies of extremely low luminosities in a wide range of environments, selected with uniform and well ...

Reconsidering maximum luminosity [PDF]

open access: yesInternational Journal of Modern Physics D, 2021
The suggestion that there is a maximum luminosity (maximum power) in nature has a long and somewhat convoluted history. Though this idea is commonly attributed to Freeman Dyson, he was actually much more circumspect in his views. What is certainly true is that dimensional analysis shows that the speed of light and Newton’s constant of gravitation can ...
