Adaptation of Cedro-Vermelha, Tarumã-Azeitona, Ingá-Doce, Branquilho-Bravo and Ocotea-Guaicá Seedlings to Shading Levels

Floresta e Ambiente, 2020
As native tree species are often used for densification, enrichment and degraded areas recovery, a better understanding of the behavior of their seedlings in response to light exposure is needed. This study evaluates the growth and morphological behavior

Humic acid in the production of ornamental lawn plugs and shading levels in the development of Carpet grass

Ornamental Horticulture
The use of biostimulants has been studied as a technology that improves the cultivation of plant species and could therefore be an option for producing turfgrass seedlings.

The Stars of Low Luminosity [PDF]

Proceedings of the National Academy of Sciences, 1952
A search has been made among the faint stars with large proper motion found on the Palomar Survey plates for objects that, statistically—judging from their magnitude, color, and proper motion—would appear to be fainter than one ten-thousandth of the sun's luminosity.

EXTRAGALACTIC HIGH-ENERGY TRANSIENTS: EVENT RATE DENSITIES AND LUMINOSITY FUNCTIONS [PDF]

, 2015
Several types of extragalactic high-energy transients have been discovered, which include high-luminosity and low-luminosity long-duration gamma-ray bursts (GRBs), short-duration GRBs, supernova shock breakouts (SBOs), and tidal disruption events (TDEs ...

Higher light intensity and mat temperature attract piglets to creep areas in farrowing pens

Animal, 2019
Loose farrowing pens have been considered as alternatives to crates to enhance sow welfare. A major concern with pen systems is often higher piglet pre-weaning mortality, especially due to crushing by the sow.

The rate and luminosity function of long Gamma Ray Bursts [PDF]

, 2015
We derive, adopting a direct method, the luminosity function and the formation rate of long Gamma Ray Bursts through a complete, flux-limited, sample of Swift bursts which has a high level of completeness in redshift z (~82%). We parametrise the redshift

Simulations and experimental results of beam-beam effects in SuperKEKB

Physical Review Accelerators and Beams, 2023
The beam-beam interaction is one of the most critical factors determining the luminosity performance of colliders. As a circular collider utilizing the crab-waist scheme, multiple factors, such as beam-beam, crab waist, impedances, etc., interact to ...

Dust Absorption and the Ultraviolet Luminosity Density at z ≈ 3 as Calibrated by Local Starburst Galaxies [PDF]

, 1999
We refine a technique to measure the absorption-corrected ultraviolet (UV) luminosity of starburst galaxies using rest-frame UV quantities alone and apply it to Lyman-limit U dropouts at z ≈ 3 found in the Hubble Deep Field (HDF).

Taxas de crescimento de mudas de catingueira submetidas a diferentes substratos e sombreamentos Growth rates of catingueira seedlings submitted to different substrates and shading

Revista Árvore, 2009
A catingueira (Caesalpinia pyramidalis Tul.) é uma espécie nativa da caatinga dotada de grande resistência à seca e de grande potencial econômico. No entanto, não existem informações sobre o desenvolvimento dessa espécie em diferentes substrates e ...
